Intent Service Do Not Get Started When Called From A Broadcast Receiver

I am working on an app in which on receiving a message i need to start a service. But my Intent service is not running. Here is what I am doing: Broadcast Receiver: public void onR

Solution 1:

My first question would be: Is your broadcast receiver working? Is the toast in your broadcast receiver being displayed? Second question: Did you declare your intent service in manifest? You can do so the following way:

<serviceandroid:name="yourPackage.ResponseService" >

Solution 2:

The exception, java.lang.InstantiationException really solved my problem. I was missing a zero argument public constructor. I just changed

public ResponseService(String name) 
        {
        super(name);
        // TODO Auto-generated constructor stub
    }

Into:

public ResponseService() 
        {
        super("ResponseService");
        // TODO Auto-generated constructor stub
    }

And now it's working really well. Hope it might help others as well.

You should use a WakefulBroadcastReceiver:

A WakefulBroadcastReceiver is a special type of broadcast receiver that takes care of creating and managing a partial wake lock for your app. It passes off the work of processing the SMS to a your ResponseService (IntentService), while ensuring that the device does not go back to sleep in the transition, so your Intent Service will run correctly.

publicclassYourReceiverextendsWakefulBroadcastReceiver {
    @OverridepublicvoidonReceive(Context context, Intent intent) {
        // Explicitly specify that ResponseService will handle the intent.ComponentNamecomp=newComponentName(context.getPackageName(),
                ResponseService.class.getName());

        this.con=context;
        Toast.makeText(context,"Broadcast received", Toast.LENGTH_LONG).show();

        Bundlebundle= intent.getExtras();
        Object[] messages = (Object[])bundle.get("pdus");
        SmsMessage[] sms = newSmsMessage[messages.length];

        for(int i=0;i<messages.length;i++)
        {
            sms[i] = SmsMessage.createFromPdu((byte[]) messages[i]);
        }

        StringsmsFrom= sms[0].getDisplayOriginatingAddress().toString();

        Intent in= newIntent(context, ResponseService.class);
        in.putExtra("sender",smsFrom)
        // Start the service, keeping the device awake while it is launching.
        startWakefulService(context, (intent.setComponent(comp)));
        setResultCode(Activity.RESULT_OK);
    }
}

And your IntentService will be like:

@OverrideprotectedvoidonHandleIntent(Intent intent) {
        Bundleextras= intent.getExtras();


        if (!extras.isEmpty()) {  

            //Do something

        }
        // Release the wake lock provided by the WakefulBroadcastReceiver.
        YourReceiver.completeWakefulIntent(intent);
    }

I have done alarms before but you can easily forget to declare it along your wakefulbroadcastreceiver in your manifest.xml.
