Android 6.0: Get package name of current activity [duplicate]

Answer 1

Get the package name:

getApplicationContext().getPackageName();

Refer to this as well: Get package name.

Answer 2

This code is unnecessary:

//get package name of current running application.
ActivityManager mActivityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
packageName = mActivityManager.getRunningAppProcesses().get(1).processName;

Try this:

grdPhoto.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        //get package name of current running application.
        Log.e("Package name:===========      ", "Package name     " + getApplicationContext().getPackageName());
           }
});

If that doesn't work, you know there's a problem with your ontemclicklistener, so try this in your oncreate method or as a log to show proof that getApplicationContext().getPackageName() will get the correct application package name.
