Starting a process when the phone turns on and Keep it running when the app closes. Android

Question

I am new to android and I am trying to learn by doing some basics projects. The current app I am working on requires me to use BroadcastReceiver, but I need it to run when the phone starts and when the app closes.

I need it to receive all the incoming SMS, even when the app is not running.

Currently I have a startForeground which uses a notification to run. Is there a way to make the app run without the notification?

Please help. Here is my code:

public class IncomingSMS extends Service {
    // Get the object of SmsManager
    final SmsManager sms = SmsManager.getDefault();

    //get audioManager
   AudioManager aud;

    public void onCreate(){
        Log.i("MyActivity",  "aaa");
        IntentFilter filter = new IntentFilter();
        filter.addAction("android.provider.Telephony.SMS_RECEIVED");
        filter.addAction(android.telephony.TelephonyManager.ACTION_PHONE_STATE_CHANGED);



        registerReceiver(receiver, filter);

registerReceiver(receiver, filter);
    Notification notification= new Notification();
    startForeground(1, notification);


    }

    public void onDestroy(){
        unregisterReceiver(receiver);
        Log.i("MyActivity",  "Destroyed");
    }
    public int onStartCommand(Intent intent, int flags, int startId){
        return START_STICKY;
    }


    private final BroadcastReceiver receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            // Retrieves a map of extended data from the intent.
            Log.i("MyActivity",  "aaa");
            final Bundle bundle = intent.getExtras();
            aud = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

            try {


                if (bundle != null) {
                    Log.i("MyActivity",  "Bundle");

                    final Object[] pdusObj = (Object[]) bundle.get("pdus");

                    for (int i = 0; i < pdusObj.length; i++) {

                        SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);

                        String message = currentMessage.getDisplayMessageBody();
                        Log.i("MyActivity",  message);
                         //Some Code



                    } // end for loop
                } // bundle is null




            }catch (Exception e) {
                Log.e("SmsReceiver", "Exception smsReceiver" + e);
                Log.i("MyActivity",  "bbb");
            }
        }
    };


    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
}

And AndroidManifest.xml:

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="pi.sum.nesbtesh.SARA" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="......"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
       <service android:name="......">
           <intent-filter>
               <action android:name="android.intent.action.BOOT_COMPLETED"/>
               <action android:name="android.provider.Telephony.SMS_RECEIVED" />
           </intent-filter>
        </service>


        <meta-data android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <activity android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />
    </application>
    <uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>
    <uses-permission android:name="android.permission.READ_SMS" />
    <uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
</manifest>

What you want is a BroadcastRceiever to run on phone startup, here you go. Basically you start your service in its callback.

For when the app closes, I wouldn't say that's quite possible because most of the times when you close an app, it just stats in Stopped but isn't destroyed. So I'd suggest you create a BaseActivity which is an Activity subclass that override onStop() or onPause() and start your service in this method.

Then every other Activity in your app are subclass of BaseActivity

Hi Christopher, thank you for your answer, BroadcastReciver stops running after a few minutes of startup. – user3527318 Feb 08 '15 at 18:42

BroadcastReceiver isn't supposed to run undefinitely. It just receive a broadcast from the android system and execute code. Then, in that code you start up your Service. – Christopher Francisco Feb 08 '15 at 22:02
