如何解决android.content.ActivityNotFoundException错误中的致命异常

Question

I'm trying to guide my users to the battery optimizations activity and it seems to be working for most except for some Samsung phones with Android 6 where I get

Fatal Exception: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.IGNORE_BATTERY_OPTIMIZATION_SETTINGS }

This error Showed in OPPO F3 Mobiles, This is what I am using to launch it

Intent intent = new Intent("android.settings.IGNORE_BATTERY_OPTIMIZATION_SETTINGS");
startActivity(intent);

Any idea what I should be launching on those phones?

Thanks.

On some devices this activity may not exist, because of custom firmware.

You can check your intent by using this method:

private static boolean isIntentAvailable(@NonNull Context context, @NonNull Intent intent) {
    return context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY).size() > 0;
}

And when you do startActivity do this:

Intent intent = new Intent("android.settings.IGNORE_BATTERY_OPTIMIZATION_SETTINGS");
if (isIntentAvailable(this, intent)) {
     startActivity(intent);
} else {
     // Do something else
}

Or catch your exception. Or find these custom activities on problem devices and call them.
