来自异步子类的Android应用程序finish（）

Question

I am using an Async Class as a subclass. After the success successful completion, I want to go to an activity, suppose ListActivity.

But after reach ListActivity, When I click on "back" it coming back to the previous activity itself. So I tried "finish()". But I am getting an error.

My code looks like.

protected void onPostExecute(String result) {

        if(flags.equals(1)){
            Intent homepage = new Intent(GCMIntentService.this, ListActivity.class);
            homepage.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(homepage);
            finish();
        }
        else {

Can any one have any idea about how to use finish() in Async Subclass ?

Thanks in advance

Answer 1

Delete your current activity after start the intent, calling currentActivity.this.finish();

    protected void onPostExecute(String result) {

        if(flags.equals(1)){
            Intent homepage = new Intent(GCMIntentService.this, ListActivity.class);
            homepage.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            startActivity(homepage);
            currentActivity.this.finish()
            ...
         }

YourClassName.this.finish() where YourClassName is the name of the class that contains the AsyncTask .

EDIT: GCMIntentService is actually an instance of GCMBaseIntentService , not an Activity . Therefore it has no finish() method. The correct way to stop a service is by calling stopSelf() (doc here ). So, to stop your service you should call GCMIntentService.this.stopSelf() . You probably don't need to do this because Android will most likely take care of it for you when you start the new Activity .

NOTE: GCMBaseIntentService has been deprecated, and it's better now to use Google Cloud Messaging API .
