How To Finish Activity From Service Class In Android?

I am developing one application in that i want to get data from server in background.I am getting data in background using service.Now i want to handle network exception,if no netw

Solution 1:

In line

((Activity) mContext).finish();

the mContext is from new InitialRequestData(InitialRequestService.this).execute();

it is the InitialRequestService, not Activity,so u get a ClassCastExcetption.

You need to pass the Activity instance to Service. But I perfer to send a BroadcastReceiver to Activity like this in your InitialRequestService:

alert.setButton("OK", newDialogInterface.OnClickListener() {

    publicvoidonClick(DialogInterface dialog, int which) {

        alert.dismiss();
        // modify hereLocalBroadcastManagerlocalBroadcastManager= LocalBroadcastManager
                .getInstance(InitialRequestService.this);
        localBroadcastManager.sendBroadcast(newIntent(
                "com.durga.action.close"));
                }
            });

in Activity which you want to close:

publicclassYourActivityextendsActivity{

    LocalBroadcastManager mLocalBroadcastManager;
    BroadcastReceivermBroadcastReceiver=newBroadcastReceiver() {

        @OverridepublicvoidonReceive(Context context, Intent intent) {
            if(intent.getAction().equals("com.durga.action.close")){
                finish();
            }
        }
    };

    protectedvoidonCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mLocalBroadcastManager = LocalBroadcastManager.getInstance(this);
        IntentFiltermIntentFilter=newIntentFilter();
        mIntentFilter.addAction("com.durga.action.close");
        mLocalBroadcastManager.registerReceiver(mBroadcastReceiver, mIntentFilter);
    }

    protectedvoidonDestroy() {
        super.onDestroy();
        mLocalBroadcastManager.unregisterReceiver(mBroadcastReceiver);
    }
}

Hope it helps.

Solution 2:

I think you have to pass simple intent from service like following.

IntentmyIntent=newIntent(First.this,Secound.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
BundlemyKillerBundle=newBundle();
myKillerBundle.putInt("kill",1);
myIntent.putExtras(myKillerBundle);
getApplication().startActivity(myIntent);

Then in Secound.class

onCreate(Bundle bundle){
if(this.getIntent().getExtras().getInt("kill")==1)
    finish();
}

Otherwise go with the BroadcastReceiver.see the example below.
