In an given Android activity, I would like to start a new activity for the user at some point. Once they leave the first activity and arrive at the second, the first activity is stale and I want to remove it completely so it can not be accessed again from the back button.
How is the best way to accomplish this? How do I kill or destroy this activity immediately after the user has launched the new activity?
This question is related to
android
Finally, I got a solution!
My Context is:- I want disconnect socket connection when activity destroyed, I tried to finish() activity but it didn't work me, its keep connection live somewhere.
so I use android.os.Process.killProcess(android.os.Process.myPid());
its kill my activity and i used android:excludeFromRecents="true"
for remove from recent activity .
Yes, all you need to do is call finish() in any Activity you would like to close.
You can also add android:noHistory="true"
to your Activity
tag in AndroidManifest.xml
.
<activity
...
android:noHistory="true">
</activity>
Add this attribute to you activity in manifest file. android:noHistory="true"
You just need to use below code when launching the new activity.
startActivity(new Intent(this, newactivity.class));
finish();
you can use:
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
Write this in each "new activity" after you initialized your new intent->
Intent i = new Intent(this, yourClass.class);
startActivity(i);
finish();
Setting android:noHistory="true"
on the activity in your manifest will remove an activity from the stack whenever it is navigated away from. see here
