I'm making an app that shows a notification each time the screen is unlocked. To that purpose, I have made a BroadcastReceiver that starts a Service. Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="android.example.example">
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="example"
android:largeHeap="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:hardwareAccelerated="true"
android:label="example" />
<receiver android:name=".RestartNotifications"
android:enabled="true"
android:exported="true">
<intent-filter>
<category android:name="android.intent.category.DEFAULT"/>
<action android:name="android.intent.action.USER_PRESENT"/>
</intent-filter>
</receiver>
<service
android:name=".NotificationService"
android:enabled="true"
android:exported="true"/>
</application>
</manifest>
The broadcast receiver is really simple and looks like this:
public class RestartNotifications extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "Hello World!", Toast.LENGTH_LONG).show();
Intent i = new Intent(context, NotificationService.class);
context.startService(i);
}
}
I have added a Toast to check if the error is due to not receiving the broadcast or due to an error in the service. When I install the app, it works fine and the notification appears every time I unlock the phone even if another app is opened and mine is stopped. However, if I kill my app, when I unlock the phone, the notifications don't appear anymore.
