Tapping a notification in the notification centre can result in app being relaunched!

To reproduce:

1. Send an Android notification that does not contain a data element while the app is running in the background.

2. Tap on the notification in the notification centre.

3. Repeat a few times.

What I noticed is that when tapping the notification my app appeared to re-launch itself even though it was already running. After trying a couple of times I realised that the app was launching multiple copies of itself - each tap resulted in a new instance of the JS app… but only 1 runtime - so I have multiple apps running side by side with a single UI!

It does not appear to happen if the push notification contains a data element.

@npomfret @mikelambert thanks for your answers. I fixed my problems with an attribute in my AndroidManifest.xml. I added android:launchMode="singleTop" to the main activity element.

<activity
   android:name=".MainActivity"
   android:label="@string/app_name"
   android:launchMode="singleTop"
   android:configChanges="keyboard|keyboardHidden|orientation|screenSize">
   ...
</activity>

Maybe this helps s.b. else!

The deep linking docs recommend "singleTask" - https://facebook.github.io/react-native/docs/linking.html -

I havent tried the push notification module yet. But does anyone know how that compares to with @jk94 approach above of android:launchMode="singleTop"?
