Resume Application from a Notification

I have created a notification when user opens an activity, if user put app in background and touch up in notification, app tries to re-open activity, but in fact a new activity is opened and last data is lost.

Can anyone help me?

So for me this worked;

<activity android:name=".YourActivity" android:launchMode="singleTop">

Single task like suggested in the approved answer does work as well, but it's not recommended;

"singleTask and singleInstance — are not appropriate for most applications, since they result in an interaction model that is likely to be unfamiliar to users and is very different from most other applications."

You can try making the Activity as a single task by adding android:launchMode="singleTask" to your AndroidManifest.xml. Something like this:

<activity
    android:name=".YourActivity"
    android:launchMode="singleTask">

Then you need to handle the new data via onNewIntent(), something like this:

public class YourActivity extends Activity {

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity);
    ...
    processExtraData();
  }

  @Override protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent);
    processExtraData();
  }

  protected void processExtraData() {
    Bundle extras = getIntent().getExtras();

    ...
    // process the extra here.
  }
}
