问题 I have an Android service that in onDestroy() method I'm sending a broadcast to restart my service. It's work on sony and samsung rom! but not work in Xiaomi or Huawei rom. How do I handle this? This is my code. Manifest: <receiver android:name=".Receiver.AppStartReceiver" android:enabled="true"> <intent-filter> <action android:name="example.app.start" /> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> Service: public class NotificationsService

问题 (NOTE that at the end of this Question I have an EDIT in which I have replaced one method with what the Answer said to do in order to fix the problem of onReceive never getting called and added onDestroy to fix a new problem that cropped up after fixing first problem. ) Here's how I attempted to capture the broadcast data, but onReceive never gets called since Log.w never displays anything: public class MatchesActivity extends Activity implements DatabaseConnector.DatabaseProcessListener {

问题 I have two Xamarin Android apps -- let's call them "Archy" and "Mehitabel". Archy has some persistent state information (which, let's say for the sake of argument, is in a SQLite DB). If a certain thing happens to Mehitabel, she needs to know a piece of that state information. To accomplish this feat, I have Mehitabel send an intent to Archy. Archy has a broadcast receiver that hears it, gathers the necessary state, and fires a different intent back to Mehitabel. Here's the code from Archy:

问题 I know there are dozens of similar threads on SO about this topic but I just couldn't find one that really solves the problem / or identifies the root cause. First of all, I'm targetting SDK 22 (Android 5.1) which means I could use the AlarmManager + WakefulBroadcastReceiver + IntentService even if this is not the latest way of doing things. I'm not interested in the JobScheduler etc solutions, I just want to understand what is happening and why. The phone I'm testing on has Android 8.0, but
