OnHandleIntent() not called in IntentService

阅读更多关于 OnHandleIntent() not called in IntentService

I know this question has been asked before, but I've been over all of the answers I could find and still haven't been able to solve the problem. The issue is that when by BroadcastReceiver starts the IntentService onHandleIntent() isn't called. Weirdly enough the constructor does run (as I can see by the Log output). This is my code: NoLiSeA.class (This class contains the BroadcastReceiver that starts my service) public void toProcess(StatusBarNotification sbn) { LocalBroadcastManager.getInstance(this).registerReceiver(notificationForwarder, new IntentFilter("to_forward")); Intent intent = new

In other words, how can I keep my service running even if my app is closed from recent apps?

阅读更多关于 Native crash in /system/lib/libart.so

I have an app on the Play Store, it has an IntentService that does some work when the app starts, and it's causing native crashes on Android 5.0. This service just scans the assets folder for app updating purposes. Specifically, this crash seems to happen on Samsung S5 after the ugrade to Lollipop, but I don't know if it's strictly related to that device, as it's an Italian app and here that's still the only widely diffuse (i.e. that I know of) device that's getting Lollipop. However, I tried it on the emulator, with stock Android 5, and it's working fine. I'm attaching the stack trace, any
