Capturing clicks on Android

Foreground/background notifications are inconsistent at the moment (a common theme for all multi-platform push notification libraries).

On iOS, receiving a remote notification in foreground immediately triggers the onNotification event handler with foreground: true. If the app is in background when the notification arrives, clicking the notification will trigger the onNotification handler with foreground: false.

On Android, foreground notifications work the same. But in background, when the notification arrives, the onNotification handler triggers immediately with foreground: false. Clicking the notificiation opens the app of course, but doesn’t trigger the event handler again.

My goal is to execute some code if and only if the user clicks on a certain notification. Are there any plans to homogenize the behavior across platforms, or is there another way to determine when notifications are clicked on Android?

@osungjin @Dean177 it seems there’s a clean, permanent solution on the way https://github.com/zo0r/react-native-push-notification/issues/183, I came up with a hack until then.

After onNewIntent went away in RN 0.30, my workaround is adding the INFO intent to our MainActivity in AndroidManifest.xml. Like so:

<activity
  android:name=".MainActivity"
  android:label="@string/app_name">
  <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.INFO" />
  </intent-filter>
</activity>
<activity
  android:name=".SplashActivity"
  android:theme="@style/SplashTheme">
  <intent-filter>
      <action android:name="android.intent.action.MAIN" />
      <category android:name="android.intent.category.LAUNCHER" />
  </intent-filter>
</activity>

This makes getLaunchIntentForPackage return MainActivity, but still launches the app with SplashActivity. It could very well have catastrophic side effects, but we haven’t experienced any yet.

I forgot to say, in my original issue I wrote:

Clicking the notificiation opens the app of course, but doesn’t trigger the event handler again.

This was a bug in my setup, because our app has two activities (one for a first-time splash screen, and a different MainActivity) so onNewIntent in MainActivity.java was never called. Clicking the notification meant that onCreate in our SplashActivity.java was called instead. Thought I’d mention it it in case someone googles their way in here.
