Timber log is not printing in debug console or Logcat

Question

Log.i("Test", "Hello, Log")
Timber.i("Hello, Timber")

I can see the Log.i log in Debug console and Logcat, I don't see the Timber log in anywhere.

I/Test: Hello, Log

I'm building in stagingDebug mode. (I have 4 options, production debug and release and staging debug and release)

What I'm missing?

Make sure that you have initialised Timber in Application class. Following code might help :-

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        // This will initialise Timber
        if (BuildConfig.DEBUG) {
        Timber.plant(new Timber.DebugTree());
        }
   }
}

I'm not sure if the `new` keyword is necessary, this worked for me: `Timber.plant(Timber.DebugTree())` – claytonjwong Oct 03 '20 at 22:28

@claytonjwong that's Java code, new not required for Kotlin – Rohan Kandwal Oct 06 '20 at 11:13
In java you need to add new.But in ktx, it is to requires – Sambhav Khandelwal Jan 01 '22 at 13:54

If you're initializing Timber like this:

if (BuildConfig.DEBUG) {
    Timber.plant(Timber.DebugTree())
}

Be sure, that you're imported BuildConfig from your app package, and not something like BuildConfig's from 3rd party libraries like this: import org.koin.android.BuildConfig. I strugled with this a few times.

initialization Timber in Kotlin

class ExampleApplication : Application(){

    override fun onCreate() {
        super.onCreate()
        // init timber
        if (BuildConfig.DEBUG) {
            Timber.plant(Timber.DebugTree())
        }
    }
}

and don't forget write android:name of Application in Manifest.xml:

<application
        android:name=".ExampleApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.PostMakerMassive">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

In my case, I imported the incorrect BuildConfig. You can check if that is the issue with yours as well.

Try to add tag in Timber. It should be set (automatically) based on the information in the Manifest, but it does not always happen (e.g. for custom devices with custom OS)

So first of all plant it:

// Java
Timber.plant(new Timber.DebugTree());

// Kotlin
Timber.plant(Timber.DebugTree())

and next set tag:

// custom tag
Timber.tag("your custom tag");

// or
Timber.tag("trolololololo");

// or something (more serious) from strings:
Timber.tag(getString(R.string.app_name))

Timber log is not printing in debug console or Logcat
