AppWidget crashes launcher after configuration activity finish (Xiaomi and Huawei only)

I'm trying to display an AppWidget on device home. I can't figure why, only on Xiaomi and Huawei devices it doesn't work.

When I drag the widget on the home screen, it nicely open my config activity. I close that activity using :

private void saveConfig() {
    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(this);

    ComponentName thisAppWidget = new ComponentName(getPackageName(), 
        ConfigActivity.class.getName());

    Intent updateIntent = new Intent(this, ConfigActivity.class);

    int[] appWidgetIds = appWidgetManager.getAppWidgetIds(thisAppWidget);

    updateIntent.setAction(ACTION_APPWIDGET_UPDATE);
    updateIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds);

    setResult(RESULT_OK, updateIntent);

    finish();
}

After that, the launcher seems buggy : screen become black, recent app drawer is open, I'm not on the same page I was...

There is nothing special in the LogCat.

Everything is fine one other devices like Samsung's or OnePlus.

Does someone had similar problem ?

Any help would be gladly appreciate

EDIT If I remove the config activity from the android:configure attribute of the apwidget-provider, appwidget does appear on the home screen. It let me think that the problem is in the intent sent in the result of my config activity

You are passing an array of widgets IDs. Try to change your code to:

In onCreate add

Intent intent = getIntent();
    Bundle extras = intent.getExtras();
    if (extras != null) {
        mAppWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,
        AppWidgetManager.INVALID_APPWIDGET_ID);
    }

then do:

private void saveConfig() {

    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context);
    ConfigActivity.updateAppWidget(context, appWidgetManager, mAppWidgetId);

    Intent updateIntent = new Intent();
    updateIntent .putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId);
    setResult(RESULT_OK, updateIntent);

    finish();
}
