Apps Return to activity when third party app completes action

[geekyhawkes]

I am launching some MP4 videos from within my application using the following INTENT (in activity B):

if (v == image5) {
File file = new File(Environment.getExternalStorageDirectory()
+ "/.intro/Resources/Res5.mp4");
if (file.exists()) {
Uri path = Uri.fromFile(file);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "video/mp4");
//intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

try {
startActivity(intent);
overridePendingTransition(R.anim.zoom_enter,
R.anim.zoom_exit);
} catch (ActivityNotFoundException e) {

}
}
}

When the video completes I would like android to return to the activity that launched the intent (Activity B), but it doesnt, instead it shows the launcher activity for my app (Activity A). I have tried `FLAG_ACTIVITY_NEW_TASK` but this made no difference.

How do I set the launching activity INTENT to ensure that when the video completes Activity B is shown?

When I select the imagebutton for the video to play (with defaults reset for which video application to use) then Activity A displays behind the dialog asking which app to play the video with.

Question 2: Why does the intent listed above launch activity A?

I have tried removing and re-installing the app, but the behavior is the same.

I have checked the developer options, &quot;Don&#39;t keep activities&quot; is not enabled.

I have installed the APK on 2 different android tablets and my S4 and the behavior is the same on all devices. I also tried with a full clean and refresh from Eclipse.

I have tried removing the animation and also tried FLAG_ACTIVITY_PREVIOUS_IS_TOP and still get the same behavior. I have also tried changing the intent to launch a PDF file using code that I know works from my Activity A (main) class file. I am really confused what is going on here.

Thanks;
