how to check which Intent started the activity?

Question

I have many activities. Each one of them has an intent which refers to the same activity. Is there a way to find out which intent started the activity?

Answer 1

I found a solution that doesn't involve passing data from one Activity to another.

Use startActivityForResult in your calling activity to start the activity:

ActivityCompat.startActivityForResult(this, new Intent(this, MyActivity.class), 0, null);

In the callee Activity, you can use the following code to detect the calling activity.

    if (getCallingActivity() != null) {
        Log.d(TAG, getCallingActivity().getClassName());
    }

Hope this helps. Cheers.
