I have a problem I hope someone can help me.
I have several activities
Main Activity, Activity 1, Activity 2, Activity3
Primal Activity let's say it's a list and activities 1 to 3 are forms, in activity3 when a save ends I need to return to the main activity, but if I use finish only return to the previous one, I do not want to use startActivity because when they give it with the "return" phone button, we would return to Activity 3.
Thank you.
To achieve what you want first you have to indicate that your main activity will have only one instance using the android:launchMode attribute in the manifest.xml .
For example:
<activity
android:name="..."
android:launchMode="singleTask"
/>
Then when you need to return to your activity, you invoke it using the method startActivity :
Intent intent = new Intent(context, MyActivity.class );
intent.setFlags( Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity( intent );
FLAG_ACTIVITY_CLEAR_TOP what it does is eliminate the stack of active activities.
