Implementation of the onActivityResult method required if you use ADAL's acquireToken with a signature that receives an activity as a parameter.

onActivityResult.java

/**
 * This activity gets notified about the completion of the ADAL activity through this method.
 * @param requestCode The integer request code originally supplied to startActivityForResult(),
 *                    allowing you to identify who this result came from.
 * @param resultCode The integer result code returned by the child activity through its
 *                   setResult().
 * @param data An Intent, which can return result data to the caller (various data
 *             can be attached to Intent "extras").

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.i(TAG, "onActivityResult - AuthenticationActivity has come back with results");
    super.onActivityResult(requestCode, resultCode, data);
    AuthenticationController
            .getInstance()
            .getAuthenticationContext()
            .onActivityResult(requestCode, resultCode, data);
}
