How to make Firebase Invites work on emulator?

Question

I am testing Firebase Invites from an emulator based on tutorial from official site.

implementation 'com.google.firebase:firebase-invites:16.0.4'

Emulator used:

CPU/ABI: Google Play Intel Atom (x86)

Target: google_apis_playstore [Google Play] (API level 28)

Skin: pixel_2

I try to call activity for result like this.

private void onInviteClicked() {
    Intent intent = new AppInviteInvitation.IntentBuilder(getString(R.string.invitation_title))
            .setMessage(getString(R.string.invitation_message))
            .setDeepLink(Uri.parse(getString(R.string.invitation_deep_link)))
            .setCustomImage(Uri.parse(getString(R.string.invitation_custom_image)))
            .setCallToActionText(getString(R.string.invitation_cta))
            .build();
    startActivityForResult(intent, REQUEST_INVITE);
}

But in activityOnResult I always get Activity.RESULT_CANCELLED as a result code.

if (requestCode == REQUEST_INVITE) {
    if (resultCode == RESULT_OK) {
        // Get the invitation IDs of all sent messages
        String[] ids = AppInviteInvitation.getInvitationIds(resultCode, data);
        for (String id : ids) {
            Log.d(TAG, "onActivityResult: sent invitation " + id);
        }
    } else {
        // Sending failed or it was canceled, show failure message to the user
        // ...
    }
}

It turns out that it is because there is a crash in invites library:

This happens only on emulator and not on physical device.

Anyone knows how to make Firebase Invites work also on emulator?

Answer 1

WindowManager.LayoutParams constant 2003 is TYPE_SYSTEM_ALERT, deprecated in API level 26. either build against API 25 (which may be that physical device) or use TYPE_APPLICATION_OVERLAY instead. with a single line from the build.gradle it's difficult to understand against which API the code even runs.

hint: make sure you run this on an emulator image with Play Services installed.
