I am wanting to start a service (CheckTime) when the phone finishes booting. This appears to work, but my app immediately crashes. I get the following error "java.lang.RuntimeException: Unable to start receiver com.example.alarmtest.MyReceiver: java.lang.UnsupportedOperationException: Not yet implemented". I have been unsuccessful in my attempts to solve this problem. I am unsure if I have left something out of the manifest or not (I am fairly new to developing for android).
This is my code for MyReceiver. (the log.d for this appears)
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
#Override
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, CheckTime.class);
context.startService(startServiceIntent);
Log.d("evan alarm", "Started on Launch, android autostart");
throw new UnsupportedOperationException("Not yet implemented");
}
}
and the code for CheckTime (the log.d for this never appears)
public class CheckTime {
public void loglab(){
Log.d("evan alarm", "We are now in CheckTime");
}
}
and finally the manifest.

That's the last line of your receiver. You're throwing it yourself.
remove this line
throw new UnsupportedOperationException("Not yet implemented");

I try to launch a service at boot, but it never starts the service. I added <action android:name="android.intent.action.ACTION_POWER_CONNECTED"/> to the intent-filter of the receiver, but when I connect my android 8.0 phone to power, it also doesn't work.

Toast.makeText(context, "received", Toast.LENGTH_LONG).show(); //this never shows up when connecting to power
Intent i = new Intent(context, MainService.class);
context.startService(i);
}
}
MainService:
public class MainService extends Service {
public static boolean isRunning = false;
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
isRunning = true;
Toast.makeText(this, "Service started", Toast.LENGTH_LONG).show();
ConnectionChecker.run(this); //when device has wifi connection, this will run connected() method
}
#Override
public void onDestroy() {
isRunning = false;
}
public void connected() {
//things to do when it has wifi connection
}
}
In my MainActivity class, I start this service using the same way as in my StartAtBoot class, and there it works fine when I open the application. So the service is working fine, its just that the StartAtBoot class doesn't run the code.
ACTION_POWER_CONNECTED is not a listed exception to the limits on implicit Intent broadcasts. Your app cannot register for it in the manifest.
If your goal is to do work periodically, but only if the device has power, use JobScheduler or WorkManager.
I'm trying to add in-app purchases and when I call OpenIabHelper::launchPurchaseFlow function:
I see Google Play purchase window
onStop and onDestroy are executed in my main activity without calls to onActivityResult
So in the end I left with GooglePlay window and my dead app
I tried to start another activity via startActivityForResult and it worked fine
(nothing was destroyed and onActivityResult was called), so it seems that problem is with OpenIAB library
Therefore there's my question:
What can possibly force my activity to be destroyed after calling OpenIabHelper::launchPurchaseFlow ?
It doesn't seem to be system because it has enough memory and as I said startActivityForResult works fine.
Also there's no exceptions being trown so I'm puzzled
Any help would be appreciated

m_bOpenIabInitialized = result.isSuccess();
}
});

Have you tried changing the activity's launchMode? Maybe the singleTop launch mode will preserve your activity:
<activity
android:name=".MyActivity"
android:label="#string/app_name"
android:theme="#style/AppTheme.NoActionBar"
android:configChanges="orientation|screenSize|keyboardHidden|screenLayout"
android:launchMode="singleTop">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
You can find more about launch modes here:

I have a BroadCastReceiver and since I don't want it to keep working when the application is uninstalled so I removed the declaration of the receiver from the manifest . By doing this the receiver will only work when the application is running . That's good so far but I have a little problem which is if the user clicks "home" button on his device to get back to his device's main screen the receiver works in the background , but when he clicks "back" button the receiver will stop working . I want it to work either the user clicked home button or back button. So how to solve this problem and thanks in advance.
**Note : I'm activating/deactivating the receiver using this code :
private BroadCastReceiver myBroadcastReceiver = new BroadCastReceiver();
#Override
public void onStart() {
super.onStart();
registerReceiver(myBroadcastReceiver, new IntentFilter(Telephony.Sms.Intents.SMS_RECEIVED_ACTION));
}
#Override
public void onDestroy() {
super.onDestroy();
unregisterReceiver(myBroadcastReceiver);
}
&& my manifest is :

*Update 1 :
public void onBackPressed() {
registerReceiver(myBroadcastReceiver, new IntentFilter(Telephony.Sms.Intents.SMS_RECEIVED_ACTION));
}
The problem is only with android 2.3.6 .
With 4.x, there isn't any problem, the receiver it's ok.
I have received the registration ID with 2.3.6 but the messages are never received.

startWakefulService(context, (intent.setComponent(comp)));

GooglePlayServicesUtil.getErrorDialog(resultCode, this,
PLAY_SERVICES_RESOLUTION_REQUEST).show();
} else {
finish();
}
return false;
}
return true;
}
Check the Google play services version number and there is a pretty defined method to check Google play services a availability
Latest release of gcm using google play is very easy to implement and can be used for longer time.
See this tutorial. Hope it might help.

Hi I am working on BroadCastReciver. There are two way to define BroadCastReciver.First one is using Java code and Second one is define in AndroidManifest.xml using . In my code second one is don't work properly.please tell where am i goes wrong.
public class HotelReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
String dActionName = intent.getAction();
Log.i("My Rceiver ", intent.getAction());
if (dActionName.equals(Intent.ACTION_SCREEN_ON)) {
Toast.makeText(context, "SCREEN ON", Toast.LENGTH_SHORT).show();
} else if (dActionName.equals(Intent.ACTION_SCREEN_OFF)) {
}
}
}

I think your reciever should read
<receiver
android:name="HotelReceiver">
<intent-filter>
<action android:name="android.intent.action.SCREEN_ON"/>
</intent-filter>
</receiver>
no dot "."
Just use this code inside of onCreate() for your activity,
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
HotelReceiver mReceiver = new HotelReceiver(this);
registerReceiver(mReceiver, filter);
