I just tried the steps outlined in Getting Started twice. Both times I can walk through the whole thing, but ant debug install generates an error:

$ ant debug:

/home/j/Development/clojure/neko/build.xml:46: sdk.dir is missing. Make sure to generate local.properties using 'android update project' or to inject it through an env var

Total time: 1 second

local.properties contains a valid path to sdk.dir, I verified that.

The change introduced to keyword->static-field with commit fc4dae4 breaks neko.context/get-service because the function signature does not fit anymore.

with the most recent neko Snapshot, menu generation fails with

Assert failed: (and (keyword? widget-kw) (map? attributes))

at menu generation. The unmodifed code runs fine with beta6

How to reproduce:

• Create a standard lein-droid application, including splash screen as a MAIN category activity and a central DEFAULT activity
• Start app and central activity; The activity needs to i.e. call neko.data/get-shared-preferences which uses the global ref to neko.context/context
• Leave app by switching launcher
• Start a couple of memory-hungry processes to force activity destruction
• Launch the activity, make sure that in your test case the splash screen isn't shown again, if neccesary repeat.
• Activity will crash as soon as neko.data/get-shared-preferences is called with a RuntimeException:

clojure.lang.Var$Unbound cannot be cast to android.content.Context

It seems that the SplashActivity's static firstLaunch field is still in its previous state, causing the splash activity to directly proceed(), without calling neko.init/init again.

I'm filing this against neko rather than lein-droid, because I'd like to propose that the use of neko.context/context should be completely removed from the library. It appears to me that the current solution is neither idiomatic for Clojure nor for Android ...

Update 2014-03-14: You may have to implement a sticky service that's restarted once the starting activity is destroyed to reproduce.

The text-size trait uses the setTextSize (float size) method, which according to the API docs takes a size in scaled pixels, that is :sp

However the trait applies to-dimension, which yields px, resulting in overall larger text than intended.

Proposed Fix: Use setTextSize (int unit, float size) directly, skipping the manual conversion.

About a week ago I could run lein droid jar on the 4.0 branch just fine, but today I tried again after pulling and got this:

/home/artur/Git-Projects/neko/src/java/neko/App.java:17: error: cannot find symbol
        DalvikDynamicClassLoader.setContext(this);
                                ^

  location: class DalvikDynamicClassLoader

Hi,

First of all, thanks a lot for your work! I'm currently playing with the combo lein-droid/neko and I think that it could be awesome to have some more examples (like how to interact with a web-view in a layout. I looked at the documentation and there https://github.com/sattvik/Clojure-Android-Examples/blob/master/basic/src/clojure/com/sattvik/android/clojure/basic/ClojureBrowser.clj, but the latter seems to be outdated).

;;;;;;; this gives IllegalArgumentException while compiling
(def ui (make-ui [:linear-layout {}
                  [:text-view {:text "doh"}]]))

(defactivity foo.bar.MainActivity
  :def a
  :on-create
  (fn [this bundle]
    (on-ui
     (set-content-view! a
      (make-ui [:linear-layout {}
                [:text-view {:text "Hello from Clojure!"}]])))))
;;;;;; ^^ this does not - what's the deal??

This does not occur when I disable aot for the given namespace.

PS. I'm not really sure whether it's really a neko issue, or whether maybe it belongs to lein-droid or whether is it beyond the scope of clojure-android, I was just unable to figure out the cause and I decided to report it here.

First of all, thanks for the great and constant work you put in neko. I wanted to get in touch with android development in clojure. But after creating a project as described, using:

$> lein droid new clojuroid org.stuff.clojuroid :activity MyActivity :target-sdk 19 :app-name ClojureMeetsAndroid

I try to build it with lein droid build and get an OutOfMemory exception:

I tried different neko versions, increasing jvm memory, cleaned up my profiles.clj. I even tried those steps on different machines. Non of my actions could prevent this from happening.

What am I doing wrong?

I use:
java 1.7.0_21,
neko 3.x
lein-droid 0.2.3
leiningen 2.2.0

I am having a terrible time trying to get neko to work in release mode. In development mode it works perfectly. In release mode, Big Trouble.

I'm first of all able to get it to fail spectacularly with the bare minimum template hello world app from

lein droid new release-crash-test  test.crash

I'm using [lein-droid "0.2.0"] and javac 1.7.0_03.

Trying to build the example provide by lein-droid's new template, without any changes, and using "lein droid release", I get this assplosion:

What the... why? What? That's weird.

OK OK, maybe my stubborn clinging to javac 1.7 is a problem. I update-alternatives and set javac and java to 1.6.0_45.

And yes, I'm remebering to run "lein clean" before each of the above compilations, just to make sure.

So, at this point I have to give up on trying to make an app with lein-droid and neko. Sadly, I had a working app already finished and ready for testing, but only when built as debug. If release builds crash in bizarre and inexplicable ways then I guess there's no point in continuing the project. Oh well. It was fun for a while though. Could be very promising in the future.

Is this project defunct?

Hi,

So I've been experimenting with references and watches, and I came with idea of a trait that allows you to hook to the reference and alter the widget when reference value changes:

(deftrait :ref-text [^android.widget.TextView wdg {:keys [ref-text]}]
  (add-watch ref-text nil
             (fn [_ _ o n] (post wdg (.setText wdg n)))))

This helped me to refrain from fetching widgets by ids/vars and just allowed to focus on the values prepared for them:

(def txt (atom nil))

(def ui [:linear-layout {:id-holder true}
         [:text-view {:text "Hello from Clojure!!!"}]
         [:edit-text {:text "Initial text" :ref-text txt}]])

(reset! txt "Some other text")

There is one issue here: I haven't hooked to the widget destroy event to release the reference that watcher holds (I haven't yet found the way to do it, am not very knowledgeable in android SDK ;) ), but I'm pretty sure it can easily be done.

Real question is, do you think it would be feasible to alter existing traits to work this way if the value specified is a reference (just additional case)? Many traits would benefit from such thing, and it would give neko that 'reactive' feel (possibility of using dataflow programming a'la javelin for example, is so tempting). Or whether it's better as an 'add-on' (like I did in my code)?

Does ref-adapter work?

I'm trying to use ref-adapter, looks very cool, but explodes at runtime with, among other things, the following:

E AndroidRuntime(7164)        Caused by: java.lang.ClassNotFoundException: neko.ui.adapters.InterchangeableListAdapter

It's unclear from the stacktrace where exactly the failure is, but it happens at the SplashActivity, and the code which calls ref-adapter is:

(defn schedule-adapter []
  (adapters/ref-adapter
   (fn [] [:text-view {}])
   (fn [_ view _ show]
     (on-ui
      (.setText view (format-show show)))) 
   schedule/schedule
   :future))

My versions of things are:

Leiningen 2.3.4 on Java 1.7.0_03 OpenJDK 64-Bit Server VM

And Android SDK 22.3.

And some project stuff:

And I'm building with lein-droid doall.

I've tried cleaning with lein clean, and wiping out the old APK on the device.

The device is a TF101 running CM 9.1.

Indeed, I looked into the classes.dex and if I am reading it correctly the class is not in there, though it is referenced:

  source_file_idx   : 15306 (adapters.clj)

And, looking in target/classes, there's nothing there either.

find target/ -name '*InterchangeableListAdapter*'
$

So, it looks like this class is not getting compiled at all? Why would that be? Is there something wrong with my toolchain, is there something I have misconfigured, or is something missing from neko?

It's possible that I've done something wonky, but I have image-buttons being defined in an adapter for a GridView, and for the most part working properly. However, calling a function defined elsewhere in the same file in the onClick procedure is causing "java.lang.RuntimeException: Unable to resolve symbol: in this context, compiling:(NO_SOURCE_PATH:0:0)" errors, even though the same exact call can be run, successfully, in the REPL.

In fact, what it's doing is looking up an entry in a predefined map, 'function-name, and eval-ing that to call function-name, which it isn't finding. Am I missing something here, or is the onClickListener having issues with either the scope or the quoting somehow?

Hi there,

I'm looking to create a custom drawing as part of a component. In the Android API it seems I'd subclass view and implement onDraw to draw directly on the canvas. I'm not sure in neko if it's possible to do this without writing my custom component in Java - it seems custom elements need a classname.

Any pointer much appreciated,
Cheers,
Dean

My problem is that I'm not getting get-service to work with :location, but instead get "object is not an instance of the declaring class" exception. (get-service :alert) leads to "Unable to find static field: ALERT_SERVICE in class android.content.Context". Any ideas what I am doing wrong?

how to get phone camera access using neko?

Hello and thank you for the great library.

I haven't been able to figure out the best way to interface directly with the android API, specifically I need to access the Bluetooth functionality. (http://developer.android.com/reference/android/bluetooth/package-summary.html)

Looking through your documentation I don't see any sensor interfacing (could be missing it). So I assume that Neko doesn't have built in Bluetooth interaction.

Is it possible to do this via direct interop? If so how would you suggest I start?

Thanks,
-Boris

I got this to work on lollipop as the issue on clojure-android/clojure but nrepl doesn't start because when I try to connect I get a connection refused error. Is this just temporary or is this an issue? Here's my project.clj https://gist.github.com/rhg/b03df0b3c1f6bd92731f

Issue by osbert from Tuesday Jul 09, 2013 at 22:38 GMT
Originally opened as #3

I'd like to deploy my own releases/snapshots to clojars to be able to make my own changes to neko and/or experiment with neko.ui.menu given that 3.0.0-SNAPSHOT is currently a bit old, but can't seem to find any documentation on how to build a neko jar suitable for deployment to clojars. I've tried:

lein jar - Fails because it cannot find symbols like android.view.View, android.widget.BaseAdapter when trying to compile InterchangeableListAdapter.java.

ant -Dsdk.dir=$ANDROID_HOME release - This seems to call into the android build system which also fails due to the error message, "Unable to resolve project target 'android-7'.

Please advise. Thanks.

I'm trying to use an image in an :image-view which lives in /res/drawable-*/dummy_image.png.

When I try to reference that image using android.R$drawable/dummy_image I see the following exception: Caused by: java.lang.RuntimeException: Unable to find static field: dummy_image in class android.R$drawable

I tried to use :constructor-args with a View class that has a constructor with two arguments, the second beeing a primitive int.

[:my-view {:constructor-args [256]}
results in following error
java.lang.NoSuchMethodException: <init> [class android.content.Context, class java.lang.Long]

[:my-view {:constructor-args [(int 256)]}
results in following error
java.lang.NoSuchMethodException: <init> [class android.content.Context, class java.lang.Integer]

I believe the only way to support this case, is to add some kind of special syntax or metadata to :constructor-args.

Besides the weight layout param, could you also add gravity for linear-layouts?

Providing a vector to :layout-height or :layout-width such as [10 :dp] leaks the Activity because eventually to-dimension is called with an Activity Context as a parameter ((.getContext wdg)), which then calls get-display-metrics if it gets a vector. get-display-metrics is memoized, so it keeps a reference to its parameter, the Activity, which then prevents the Activity from getting garbage collected after it finishes.

To reproduce:

1. Create two activities with relative-layouts or linear-layouts in them
2. Use vector dimensions in the layout-width and/or layout-height
3. Go back and forth between the activities
4. Use a memory profiler to view the memory usage, filter by the activity names
   Result: You should see multiple instances of each activity kept in memory
   Expected result: You should only see at most one instance of each activity

To fix, either:

1. Use (.getApplicationContext (.getContext wdg)) instead in various parts in traits.clj.
2. Stop memoizing get-display-metrics.

Note: For any users out there reading this, it remains safe to provide a vector to :text-size since it doesn't call to-dimension.

I'm using 3.2.0, but looking at the latest source the issue should still happen.

neko.ui/traits.clj references static fields of android.widget.RelativeLayout, such as (among others) ALIGN_PARENT_END, which have only been introduced in API 17.

This breaks neko for all target APIs < 17.

Here is the exception stacktrace whis is helpful as they are https://www.refheap.com/77772

from what I gather something is trying to define a class java.lang.XXX, but what?

Hi Alex,

There are two misspellings in neko.init:

• https://github.com/clojure-android/neko/blob/master/src/clojure/neko/init.clj#L26
• https://github.com/clojure-android/neko/blob/master/src/clojure/neko/init.clj#L64

"::start-nrepl-sever" should be "::start-nrepl-server"

I detect this when hacking TBNL (https://github.com/pw4ever/tbnl) to make REPL work in release mode :)

Wei.

If I specify a :on-editor-action in a text-view's map like the following, I get an exception saying there's no such method .setOnEditorAction.

[:edit-text {:on-editor-action
                 (fn [view _action _event] ...)}]

I tried :on-editor-action-listener, but I get the same problem.

Env:

• neko 3.0.1
• Ubuntu 13.04 x86_64
• Android 4.0.3 (not emulator)

I want to execute initialization logic in MyApplication.onCreate().

• load configuration from database

I wrote clojure.lang.Var.invoke() in onCreate() like this:

  public void onCreate() {
    Log.v(TAG,"--- onCreate() in ---");

    Symbol APPLICATION = Symbol.intern("myapp.application");
    REQUIRE.invoke(APPLICATION);

    Var ON_CREATE = RT.var("myapp.application", "app-on-create");
    ON_CREATE.invoke(MyApplication.this);
  }

and got error: java.lang.ClassCastException: clojure.lang.Var$Unbound cannot be cast to clojure.lang.Var

app-on-create calls neko.data.sqlite/get-database, and it calls neko.data.sqlite/create-helper function.
But neko.context/context is unbound at that time. It causes the error.

So, I fixed app-on-create like this:

(defn app-on-create
  [this]
  (do
    (if (not (bound? #'neko.context/context))
      (alter-var-root #'neko.context/context (constantly this)))
    ; and my code...

This code works...but the solution is correct?

Using 3.0.0-beta5. I get a NullpointerException when using this (stripped down from your more elaborate example on http://clojure-android.blogspot.de/).

In case it's relevant: MainActivity expands an XML Layout, and it works like a charm when run from
:on-create-options-menu in defactivity.

(defn MainActivity-onCreateOptionsMenu [this menu]
  (make-menu
   menu [[:item {:title "First"
                 :show-as-action :never}]
         [:menu {:title "Submenu"
                 :show-as-action :never}
          [:item {:title "Second"}]]
         [:group {:id :not-important}
          [:item {:title "Third"
                  :show-as-action :never}]
          [:item {:title "Four"
                  :show-as-action :never}]]]))

I wrote tests years ago, but now they are all disabled. We need to develop a strategy to get them working again.

As it says in the title, I changed my app to use API level 10 and my previously fully working splash stopped changin 'Application Name' to the app's name. As an example on my account there is github.com/rhg/sandbox which displays the bug. Thank you for saving me from the horrors of java (well partly).

Looks like marginalia docs are missing, the link to http://alexander-yakushev.github.io/neko/ gives me 404. Tried to generate them myself but that failed with missing android.* packages.

Hello, I'm trying to use neko(3.1.0-SNAPSHOT / 3.0.2) on emulator/real device Nexus 5 with latest stable version of Android KitKat. On dalvik runtime my application with neko loads just fine, but on ART runtime I get an error that is posted in the end of the post. I did a little bit of searching and it seems that function neko.compilation.clear-cache is rejected by Android verifier because 'it is too complex'. Any response to this would be highly appreciated. Thanks, Martin.

The following crashes my activity during start up:

  (ns mynamespace.main
    (:use [neko.ui.adapters :only [ref-adapter]])

Getting:

E/AndroidRuntime(  680): java.lang.ExceptionInInitializerError
E/AndroidRuntime(  680):    at java.lang.Class.classForName(Native Method)
E/AndroidRuntime(  680):    at java.lang.Class.forName(Class.java:251)

From cider doing without the line that crashes it:

(use '[neko.ui.adapters :only [ref-adapter]])

gives:

java.lang.ClassNotFoundException: neko.ui.adapters.InterchangeableListAdapter

I have been trying to follow some tutorials on android clojure development, mainly this one:
https://github.com/alexander-yakushev/events/blob/master/tutorial.md

However I can't get the *a macro to work correctly. At the moment I try to work directly from a "lein droid repl" in the console as I had some problems with cider before so I want to make sure that my problems with the *a macro is unrelated to that.

Am I doing something wrong here? What?
Should *a evaluate to nil?

When I evaluate the on-ui form I get the following error on the phone:
java.lang.AssertionError: Assert failed: (instance? Activity activity)

Any suggestions on what I should do to solve this problem?

This is what I do:

rm -Rf events3/
lein new droid events3 org.stuff.events :activity MainActivity :target-sdk 15 :app-name EventsListing
cd events3/
lein droid doall

At this point I get the default application on my connected phone (Galaxy Note 3 android 5.0) and everything looks good. I start the repl:

lein droid repl

  (debug/safe-for-ui
   (view/find-view (debug/*a) ::playing-button))

returns nil

but the view that is set at onCreate time definitely has an element with that id, and I can see it displayed. When run from inside the program (rather than the repl), using this instead of (debug/*a), it also returns nil.

Interestingly, in attempting to debug this, I tried this from a REPL:

  (debug/safe-for-ui
   (activity/get-decor-view (debug/*a)))

And got a strange

#object[com.android.internal.policy.impl.PhoneWindow$DecorView 0xa104b800 "com.android.internal.policy.impl.PhoneWindow$DecorView@a104b800"]

returned instead of my view.

I'm not sure what's going on here.

Hi,

When using this dependency which is laid down by the droid template [org.clojure-android/tools.nrepl "0.2.10"], I would get the following error:

Could not transfer artifact org.clojure-android:tools.nrepl:pom:0.2.10 from/to clojars (https://clojars.org/repo/): Connect to clojars.org:443 [clojars.org/38.0.60.2] failed: Connection timed out
This could be due to a typo in :dependencies or network issues.
If you are behind a proxy, try setting the 'http_proxy' environment variable.

Using this other dependency resolved the problem: [org.clojure-android/tools.nrepl "0.2.6-lollipop"]

Let me know if you need some more info. I'm unsure of what could be causing this problem. I could always be doing something dumb :)

Callum

I am currently looking into adding better content provider support into Neko. It would be nice if the Cursor support could be more generic so that it can support all Cursor objects, regardless of source.

Came across this as I was going through Kris's tutorial. Here is the code in question:

(declare ^android.widget.LinearLayout mylayout)
(declare add-event)

(defn get-elmt [elmt]
  (elmt (.getTag mylayout)))

(defn set-elmt [elmt s]
  (on-ui (config (elmt (.getTag mylayout)) :text s)))

(defn add-event []
  (set-elmt ::listing "TEST SETTING TEXT"))

(def main-layout [:linear-layout {:orientation :vertical,
                                  :id-holder :true
                                  :def `mylayout}
                  [:edit-text {:hint "Event name",
                               :id ::name}]
                  [:edit-text {:hint "Event location",
                               :text "Partay Town!"
                               :id ::location}]
                  [:button {:text "+ Event"
                            :on-click (fn [_] (add-event))}]
                  [:text-view {:text @listing
                               :id ::listing}]])

Calling add-event in the activity crashes the app, with the error:
java.lang.ClassCastException: android.view.ViewGroup$LayoutParams cannot be cast to android.widget.LinearLayout$LayoutParams

The ref-adapter example use case, with (make-ui [:text-view {}]) as the view-creation function breaks with

android.view.ViewGroup$LayoutParams cannot be cast to android.widget.AbsListView$LayoutParams

It seems that make-ui defaults to setting ViewGroup$LayoutParams on views created without container or with an unknown container, which makes them unattachable to Listviews subsequently?

I'm having problems using the TextClock widget with neko/lein-droid. Using the older, deprecated DigitalClock works fine. The code compiles but when I run it I get a ClassNotFoundException. I've looked at issue #29 and tried changing the JDK version but that doesn't work. I've also tried fiddling with the Clojure version.

Here's the code:

(ns org.stuff.clockradio.main
  (:use [neko.activity :only [defactivity set-content-view!]]
        [neko.threading :only [on-ui]]
        [neko.ui.mapping :only [defelement]]
        [neko.ui :only [make-ui]])
  (:import [android.view View]
           [android.widget TextView]
           [android.widget TextClock]
           android.app.Activity ))

(defelement :digital-clock
  :classname android.widget.TextClock
  :inherits :text-view
  )

(def clock-layout [:linear-layout {:orientation :vertical}
                   [:digital-clock {:text-size 40} ]])

(defactivity org.stuff.clockradio.MainActivity
  :def a
  :on-create
  (fn [this bundle]
    (on-ui
      (set-content-view! a
        (make-ui clock-layout)))))

I create a lein droid project by lein new droid project your.project, then run lein droid doall success create apk and install apk to my Android.
So i open the repl lein droid repl , and test (on-ui (neko.notify/toast "Hello")) , my Android will notify "Hello" ok .
But I use Emacs Cider connect the repl (localhost:9999) , then run C-c C-k , it will Erro :

I don't know how to do, i try import VoiceInteractor class , but it's failed.

Thanks :-)

the tabs will be appended in the bar whenever the setup-aciton-bar is evaluated instead of rerender in the REPL?

Is it an issue?
