Build error

Hi @samtstern I was trying to build the project so that I could convert the newly added snippets to Kotlin but the project build fails with the following message :

The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[15.0.2,15.0.2], [16.0.0,16.0.0]], but resolves to 15.0.2. 

Any ideas as to what might be causing the trouble here?
Looked up on stackoverflow and the answers suggested updating google-services and dependencies to the latest version (which is already done).

Other Details

google-services version : 4.0.1
gradle plugin : 3.1.3

Kotlinize snippets for AuthActivity

Hi @samtstern
Would love to convert the snippets of Auth module to Kotlin, lmk if I can go ahead.

Add SDKs for Firebase products that you want to use

how to share the deep link to a specific application on the device.

@OverRide
public void sendInvite(Context context) {
super.sendInvite(context);
Toast.makeText(context, "TODO: TODO: Implement social sending", Toast.LENGTH_SHORT).show();
}
In the function, how to share the data to a specific application on the device? like facebook.

StartActivityForResult is an outdated method for doing this

snippets-android/auth/app/src/main/java/com/google/firebase/quickstart/auth/kotlin/GoogleSignInActivity.kt

Line 100 in 7268f81

startActivityForResult(signInIntent, RC_SIGN_IN)

It was misleading to some of my developers when they went from firebase docs to here and ended up using this for grabbing a result. It shows up as a deprecated library in android studio, and is considered the outdated way to do this. This likely needs to be updated.

Links for new way:
https://developer.android.com/training/basics/intents/result
https://stackoverflow.com/questions/62671106/onactivityresult-method-is-deprecated-what-is-the-alternative

The documentation recommends logging SCREEN_VIEW in the `onResume` method

The documentation recommends logging SCREEN_VIEW in the onResume method. Which one is more appropriate?

Firebase.auth appears as unresolved reference

I'll try to use the Firebase auth reference on my project, but it won't works.

Replace use of "whitelist" in code snippets with "access list" or "allow list"

Our public style guide forbids use of the term "whitelist" in favor of more neutral terms like "access control list", "access list", or "allow list". Samples from this repo containing those terms are included in pages on firebase.google.com and need to be updated to comply with our updated style guide.

what is need to be done here basically ?

We can use viewBinding in the code which is updated version and also recommended by the Google.
So please update the code

Who are you ?

What do you want ?

I am getting com.google.android.gms.common.api.ApiException: 4: 4:

I am using Firebase auth to signin user with Google, and I have setup the Firebase project with proper configuration and google-services.json and add that to my android project. I have added below dependencies in my

Add Snippets for measure ad revenue

Add in snippets for measure ad revenue for various mediation networks.

Align documentation and code sample on how to manually track screens

The Google Analytics documentation, under Manually track screens, says:

You can manually log screen_view events whether or not automatic tracking is enabled. You can log these events in the onAppear or viewDidAppear methods for Apple platforms and onResume for Android. When screen_class is not set, Analytics sets a default value based on the UIViewController or Activity that is in focus when the call is made.

The code sample, however, does it inside onCreate.

Looking at the lifecycle, having it in onResume would mean that after the device wakes from sleep, another event would be sent.

Dont mUse Hungarian notation in kotlin snippets

In reference to what @SUPERCILEX mentioned here, we should avoid hungarian notation in our Kotlin snippets.

Kotlinize dynamic-links, firebaseoptions, storage and tasks

I saw #5 and #12 and the resulting Kotlin Activities (looks great btw). So I was wondering if I could do the same for the dynamic-links, firebaseoptions, storage and tasks code snippets.
Just let me know and I'll start working on a PR

Firebase.database.getReference(".info/connected") disconnect after a minute

This reference tends to change value after a minute to false, so it blocks my access to Firebase, please tell me any solution or alternative, I just want to detect if the device has a connection to the database to make changes with the internet or just local

As the title says, the MyFirebaseMessagingService.java file is missing the sendNotification() example method which I should add to my main java Please inform me about this. Thank you

Region Tag: run_task_executor

Hi folks,
A few region tags prefixed with run_ should be changed to something like firebase_run_task_executor.

This is messing up the snippet tracker, as it assumes run_ samples associate with Cloud Run.

Can we just change the region tag or do we need to do some internal config changes too?

Convert database snippet to kotlin

Hi @samtstern
As discussed here, I would like to convert the database code to Kotlin.
Could you tell me the structure I should follow?
Should i create a new project for database in Kotlin or create a kotlin file for each java file in the current project?

Not

Docs: Code snippet for City class does not match Java version

Environment details

Documentation on https://firebase.google.com/

Steps to reproduce

1. Open the Add data to Cloud Firestore page in the docs.
2. Compare the "Java" and "Java Android" code snippets under Custom objects
3. Notice that there a significant inconsistencies, and that both versions only show part of the class.

Get prediction values from tensorflow lite android

Describe the current behavior
I want to get values from output tensor with input an image to predict the eye region landmarks.
I have predicted image from frozen graph model and Tensorflow lite using python script and it works fine.
The problem is with the Android platform, I got false and different values compared to values from python script

Describe the expected behavior

Code to reproduce the issue
Python script

data = np.asarray( img, dtype="float32" ) 

# Inference on input data normalized to [0, 1]
inputImg = np.expand_dims(data,0).astype(np.float32)
input_details = interpreter.get_input_details()
interpreter.set_tensor(input_details[0]['index'], inputImg)

interpreter.invoke()

output_details = interpreter.get_output_details()
output_data = interpreter.get_tensor(output_details[0]['index'])
print(output_data)

Phone Authentication Firebase

From 22nd January Android Play Services is unable to detect the Auto-Complete for the OTP.
Is there any guide which needs to be followed like SMS API in case of Firebase Phone Auth?

Gradle Version needs to be updated for the Android version

I get the following error when trying to build the Android Analytics Snippets
Minimum supported Gradle version is 7.0.2. Current version is 6.5.1.

It appears that this should be updated to build correctly for new users.
