I found many topic but no case fit for my question. The first my app working smooth, it is always startup with device by code bellow:
In AndroidManifest:
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
and receiver:
<!-- start when module start broadcast -->
<receiver android:name=".StartOnBoot"
android:exported="true">
<intent-filter >
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<!-- listen messenger received -->
<receiver
android:name=".Phone.SmsListener"
android:exported="true">
<intent-filter android:priority="1000">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
And class StartOnBoot
public class StartOnBoot extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)){
Intent serviceIntent = new Intent(context, MainActivity.class);
serviceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(serviceIntent);
}
} }
And now I added 2 broadcast to listen state of SD card and SIM card. But when I finish, My app can not start when my device restarted. And I don't know, where is problem, nothing clue.
<!-- broad cast SDCard receive-->
<receiver android:name=".Peripheral.SDCardListener">
<intent-filter>
<action android:name="android.intent.action.MEDIA_EJECT" />
<action android:name="android.intent.action.MEDIA_MOUNTED" />
<data android:scheme="file" />
</intent-filter>
</receiver>
<receiver android:name=".Phone.SimCardReceiver">
<intent-filter>
<action android:name="android.intent.action.SIM_STATE_CHANGED"/>
</intent-filter>
</receiver>
And 2 classes receiver:
public class SDCardListener extends BroadcastReceiver {
//restart app when SD card mounted
@Override
public void onReceive(Context context, Intent intent) {
Log.d("TAG","SDcard state : " + intent.getAction());
if (intent.getAction().equals(Intent.ACTION_MEDIA_EJECT)){
//sdcard eject
}else if (intent.getAction().equals(Intent.ACTION_MEDIA_MOUNTED)){
SDCard.getInstance().SDCardMounted();
}
}
}
for sim state:
public class SimCardReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Log.d("TAG", "Sim state :" + intent.getAction());
}
}
My device target is only Android 7.1, SDK lv 25. Some methods I tried but not work:
- I removed SimCardReceiver
- I added "android:priortity to StartBoot" like this:
<intent-filter android:priority="1000">
But still not working, Remember, my app always work without 2 broadcast SDCardListener and SimCardReceiver Extra question:
- How many broadcast are available to use in one app. How many is good ? one or not limit
- Could I merge all receiver to one broadcast
