Killing the activity when user clicks the home button

Question

Okey, this is weird. I have two activities (well, more than two, but they don't matter) - AppActivity and PopupActivity. AppActivity is my main application activity and it contains my app's settings. PopupActivity is a dialog that gets opened when user clicks the button in the notification (it's a RemoteViews notification). Well, it works. Works great. But only if user closed the AppActivity by clicking the back button. If they clicked home, PopupActivity opens after a few seconds after clicking the button. Same thing happens when user closes the PopupActivity with a home button. Clicking the button in the notification doesn't open the PopupActivity instantly, but it takes a few seconds to kill the previous activity that still exists somewhere in the background.

I've tried calling finish() in the onStop and onPause methods, but it doesn't fix my problem.

Edit: Here's the code I have:

Manifest:

    <activity
        android:name="cc.lupine.quicksocial.AppActivity"
        android:label="@string/app_name"
        android:configChanges="orientation|screenSize" android:noHistory="true" android:clearTaskOnLaunch="true" android:finishOnTaskLaunch="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity 
        android:configChanges="orientation|screenSize" 
        android:excludeFromRecents="true" 
        android:showOnLockScreen="false" 
        android:theme="@android:style/Theme.Holo.Light.Dialog.NoActionBar.MinWidth" 
        android:name="cc.lupine.quicksocial.PopupActivity" 
        android:noHistory="true"
        android:launchMode="singleInstance"
        android:taskAffinity="" 
        >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
        </intent-filter>
    </activity>
    <service android:name="cc.lupine.quicksocial.ShareService"></service>

ShareService.java (just a function that gets called when user clicks a button in the notification):

public static void startSharing(Context ctx, int n) {
    Log.d("sn", "startsharing called in shareservice");
    if(n == 1 || n == 2)
    {
        Intent i = new Intent(ThisApplication.getAppContext(), PopupActivity.class);
        i.putExtra("shareType", n);
        i.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY|
                  Intent.FLAG_ACTIVITY_CLEAR_TOP|
                  Intent.FLAG_ACTIVITY_SINGLE_TOP|
                  Intent.FLAG_ACTIVITY_CLEAR_TASK|
                  Intent.FLAG_FROM_BACKGROUND|
                  Intent.FLAG_ACTIVITY_NEW_TASK);
        ctx.startActivity(i);
    } else if(n == 3) {
        // doesn't matter for now
    }
}

PopupActivity.java (fragments):

public class PopupActivity extends Activity implements OnDataPass {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d("sn", "oncreate called in popupactivity");
        super.onCreate(savedInstanceState);
        instanceOfPopupActivity = this;
        setContentView(R.layout.activity_popup);

        ShareFragment sfrag = new ShareFragment();
        Bundle args = new Bundle();
        Bundle extras = getIntent().getExtras();
        try {
            //doesn't matter
        } catch(Exception e) { e.printStackTrace(); finish(); }
        sfrag.setArguments(args);
        FragmentManager fragmentManager = getFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.contFragment, sfrag);
        fragmentTransaction.commit(); 

    }
    @Override
    public void onPause()
    {
        Log.d("sn", "onpause called in popupactivity");
        finish();
        super.onPause();
    }
    @Override
    public void onStop() {
        Log.d("sn", "onstop called in popupactivity");
        super.onStop();
    } 
    @Override
    public void onDestroy() 
    {
        Log.d("sn", "ondestroy called in popupactivity");
        super.onDestroy();
    }

}

And if I open the popup for the first time:

05-26 14:37:14.149: D/sn(7218): startsharing called in shareservice
05-26 14:37:14.179: D/sn(7218): oncreate called in popupactivity

But when I close the popup with a home button and try to open it again:

05-26 14:38:11.620: D/sn(7218): startsharing called in shareservice
05-26 14:38:14.103: D/sn(7218): oncreate called in popupactivity

It takes a lot of time for onCreate to be called. And now, what's the reason?

Answer 1

I think you are focusing on the wrong problem (killing the activity) instead of focusing on the real problem (10 seconds to start it again).

First you need to understand WHY it is taking 10 seconds to open it if you exited the other acitivty with the home key!

If you posted more details (with source code) it would have been easier to understand and help you!

Answer 2

call finish() when you want to close app. Call finish() on both activities and watch out popup window has to be focusable to handle click.
