NotificationLog

Use an expanded notification as a makeshift Android log output console.

The design goals of this project are as follows:

• Provide an on-device view of explicit log output during app development.
• Do not disrupt the normal lifecycle of the app (no app switching).
• Transparent implementation (using the same API as android.util.Log, easily disabled).
• Minimal setup.

This library does not currently output the system LogCat, only messages explicitly logged within the app. The status of this project should be considered "experimental".

Usage

Include the jar file (run ant jar to build from source, or download it here) in your project. NotificationLog has the same API as android.util.Log. You should switch your imports to com.readystatesoftware.notificationlog.Log.

By default, NotificationLog behaves exactly the same as android.util.Log. To enable the additional notification logging, you must first initialize the class for notifications. You might want to do that in your Application class like so:

@Override
public void onCreate() {
    super.onCreate();
    if (BuildConfig.DEBUG) {
        Log.initialize(this);
    }
}

Once initialized, the Log.v(), Log.d(), Log.i(), Log.w(), Log.e() and Log.wtf() methods will write to the notification. This can be enabled or disabled at any time using the Log.setNotificationsEnabled() method.

Advanced Integration

To display a more detailed view of the log buffer and provide additional filter, level and clear actions, you must add the following to your manifest:

<activity 
    android:name="com.readystatesoftware.notificationlog.LogActivity" 
    android:exported="true"
    android:launchMode="singleTop" />

Toasts

You can have log messages additionally appear as Toasts by using the Log.setToastsEnabled() method. This is disabled by default and should not be enabled during any performance critical code. Toast notifications will not appear when the Log methods are called off of the main thread.
