Output example.java

//Calling from from MainActivity's onCreate like so:

@Override
protected void onCreate(Bundle savedInstanceState) {

	super.onCreate(savedInstanceState);

	setContentView(R.layout.activity_main);

	LogUtil.v("test v");
	LogUtil.d("test d");
	LogUtil.i("test i");
	LogUtil.w("test w");
	LogUtil.e("test e");
}

//Would cause the following log:

11-18 00:16:16.304 21659-21659/? V/MY_TAG: T:1 | MainActivity , onCreate() | test v
11-18 00:16:16.308 21659-21659/? D/MY_TAG: T:1 | MainActivity , onCreate() | test d
11-18 00:16:16.308 21659-21659/? I/MY_TAG: T:1 | MainActivity , onCreate() | test i
11-18 00:16:16.308 21659-21659/? W/MY_TAG: T:1 | MainActivity , onCreate() | test w
11-18 00:16:16.308 21659-21659/? E/MY_TAG: T:1 | MainActivity , onCreate() | test e
