Feature Request: Allow json to be printed to a different log level

Relates to #28

Is there a way to allow the json string to be logged into a different log level?

Suggestion: Make the API compatible with android.util.Log

Consider making the API compatible with android.util.Log so that switching to this library doesn't involve making too many changes to existing code. For example, consider adding the following even if you don't use the tag parameter:

public static void d(String tag, String message);

Of course one might argue that users of this library should wrap the call to Logger.d() within their own utility class if they want to seamlessly switch to it from android.util.Log. But maybe it is easier if the library provides this out of the box.

As an example, take a look at this Logging library that can be used just by changing the import statements and no other code changes.

Add checkstyle

I must init tag firstly, is that right?

I must init tag firstly, is that right?
Logger.init("TAG");

Or, I will get exception of java.lang.NullPointerException

Making a Jar

Hi Orhan,

Thats a great project. Cong. I am trying to import this project as jar. Is it possible? Can you provide a jar for lastest version?

Thanks.
Good luck

Is there any switch can close the log info when publish ?

How to output Logger.e to console when running junit test in android studio

Hi there,
The title is pretty obvious. I am be able to print log to console with e.printStackTrace() when running unit test in android studio but Logger.e(JsonUtils.class.getName(), jsonString, e).

Thanks in advance!

Suggestion: Handle Varargs in message

Hi,

I want to suggest a feature I would like before I completely agree on migrating to Logger. I think you could implement varargs feature in message string. For example, in Timber, I used to do something like that:

Timber.d("Data: %d %d %d %d %s", left, right, top, bottom, input);

Remove the hardcoded method count for t("")

For the t("") function it should use the the user defined value and not the default value of 2

How to integrate to the Timber?

I'm using https://github.com/JakeWharton/timber, then I have a question.
The log :
RequestListener.onRequestSuccess (RequestListener.java:46)
║ Timber.d (Timber.java:23)
║ Timber$1.d (Timber.java:136)
║ Timber$Tree.d (Timber.java:245)
║ Timber$Tree.prepareLog (Timber.java:319)
║ PrettyDebugTree.log (PrettyDebugTree.java:33)

How to get rid of :
║ Timber.d (Timber.java:23)
║ Timber$1.d (Timber.java:136)
║ Timber$Tree.d (Timber.java:245)
║ Timber$Tree.prepareLog (Timber.java:319)
║ PrettyDebugTree.log (PrettyDebugTree.java:33)

I just want : RequestListener.onRequestSuccess (RequestListener.java:46)

Logger call shown as last method call

Just experimenting with this library for the first time and I am seeing the Logger.d calls as on of the method calls. It seems like form your examples that should not be the case. Am I doing something wrong or is there a bug here?

Does it only work in AndroidStudio?

Getting Logger to print the name of the instance class instead of the base class

I'm getting an issue where, because a lot my classes extend some base class, most of my logs from Logger are reported with the base class name, which is not very helpful.

Please let me know if there's any easy way around this

Json can't output

    /**
     * Formats the json content and print it
     *
     * @param json the json content
     */
    @Override
    public void json(String json) {
        String tag = getTag();
        int methodCount = getMethodCount();

        if (TextUtils.isEmpty(json)) {
            d(tag, "Empty/Null json content", methodCount);
            return;
        }
        try {
            if (json.startsWith("{")) {
                JSONObject jsonObject = new JSONObject(json);
                String message = jsonObject.toString(JSON_INDENT);
                d(tag, message, methodCount);
                return;
            }
            if (json.startsWith("[")) {
                JSONArray jsonArray = new JSONArray(json);
                String message = jsonArray.toString(JSON_INDENT);
                d(tag, message, methodCount);
            }
        } catch (JSONException e) {
            d(tag, e.getCause().getMessage() + "\n" + json, methodCount);
        }
    }

break 4000 words limit

please, sometimes the json and xml can be loooooooong

Set log tag file name

Please update the documentation concerning "Use Soft Wraps"

To inform the users that to get the same pretty output, they need to disable "Use Soft Wraps". I spent a few minutes wondering why I had some an awful formatting.
With "Use Soft Wraps" enabled:

Disabled:

Optional filter for stack trace

For the stack trace on the logs I would love to be able to filter them by package (or a substring of the package)

I am thinking a very simple setting call like setStackTraceFilter("org.example.app") then only show stack trace items that contain that string.

Suggestion: Change the TAG only in one log

First of all, congratulations for the library, veeeery awesome :)

Can you add an option to change the TAG only for one log? Something like:

Logger.e("TAG", "Message");

Thank you!

1.5 does not work

I updated to 1.5, in our gradle files (since we need the stack-trace crash fix), but it does not recognise the classes from the library.

Even if I put the .aar locally in the project it does not work.

1.4 works perfectly, something wrong with the build that were uploaded to mavenCentral?

Please support log out list

As you know, some user really need print the list directory, please add this feature.

LoggerPrinter.logMethod may throw ArrayIndexOutOfBoundsException

code below in LoggerPrinter.logMethod throws ArrayIndexOutOfBoundsException when methodCount + stackOffset == trace.length

if (methodCount + stackOffset > trace.length) {
      methodCount = trace.length - stackOffset - 1;
}
...
builder.append("║ ")
    .append(level)
    .append(getSimpleClassName(trace[stackIndex].getClassName())) // ArrayIndexOutOfBoundsException
    .append(".")
    .append(trace[stackIndex].getMethodName())
    .append(" (")
    .append(trace[stackIndex].getFileName())
    .append(":")
    .append(trace[stackIndex].getLineNumber())
    .append(")");

possible solution

methodCount + stackOffset > trace.length

may be

methodCount + stackOffset >= trace.length

Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = ','

这句代码导致的
private String createMessage(String message, Object... args) {
return args.length == 0 ? message : String.format(message, args);
}

v1.12 Logger.json cause nullpoint exception but v1.11 is OK

public void getBonusData() {
        String url = HttpUrl.CLIST;
        Map<String, String> args = new HashMap<>();
        args.put("type", "1");
        HttpRequest httpRequest = new HttpRequest("CLIST_BONUS");
        httpRequest.postRequest(url, args, new HttpResponse() {
            @Override
            public void onSucceedResponse(String response) {
                Logger.json(response);
            }

            @Override
            public void onErrorResponse(VolleyError error) {
                Logger.t("CLIST_BONUS").d(error.toString());
            }
        });

how is this thread safe?

I see that there's a single printer instance saved on a static member in logger.java
so when i do this simultaneously from 2 threads:
thread1 - logger.t("tag1").i("log1")
thread2 - logger.t("tag2").i("log2")

it seems very likely that logs will be written with wrong tags.

or am i missing something?

Min SDK

Can you make min sdk to 1? Thanks!

Timber support

Love the look of this library. Would be awesome to use with @JakeWharton's Timber library https://github.com/JakeWharton/timber.

Nothing printed in logs when using .json()

I'm using the method call Logger.t("tag", 0).json(jsonString) but nothing prints in the logcat.

In case it helps I'm using the following JSON

{"coord":{"lon":-121.49,"lat":38.58},"sys":{"message":0.007,"country":"United States of America","sunrise":1432039821,"sunset":1432091674},"weather":[{"id":803,"main":"Clouds","description":"broken clouds","icon":"04n"}],"base":"stations","main":{"temp":279.79,"temp_min":279.79,"temp_max":279.79,"pressure":1018.82,"sea_level":1031.88,"grnd_level":1018.82,"humidity":91},"wind":{"speed":1.51,"deg":167.501},"clouds":{"all":64},"dt":1432033881,"id":5389489,"name":"","cod":200}

the android studio 1.3.2 didn't show the thread message. so how can i setting it?

i setting it in application oncreate method
Logger.init("MeetingPac"); // default PRETTYLOGGER or use just init()
Logger.d("testa");

the show just is : "09-17 17:15:19.276 11859-11859/com.sqlview.meetingpac D/MeetingPac﹕ ║ testa"

so the thread message?

write log to a file

Hi thanks very much for this library.

is it possible to write all log to a file along with the standard output?

Thanks

No t() method

Damn thank you!!!!

thank you for this lib!

this makes logcat 1000000x better.

is there anyway I can get this same look and feel remotely?

thanks man!

Cannot add lib to project

2 Suggestions: Debug vs Prod and Logger call

Yes, I agree this is a really cool logger. Before I can make the switch I would love to see something like Jake Wharton's Timber's approach:
if (BuildConfig.DEBUG) {
Timber.plant(new Timber.DebugTree());
} else {
Timber.plant(new CrashReportingTree());
}

The other suggestion is kind of silly, like most of us I am very lazy and typing
L.v("test2"); or even
Lg.v("test2"); is faster/simpler than typing
Logger.v("test2");

Thanks Emre
