Just return the className. The old code didn't work with activity aliases. For example, when launching with `<activity-alias android:name=".SplashActivity" android:targetActivity=".MainActivity" />`, the old code would try to get the class for `SplashActivity` which threw `ClassNotFoundException`.

by just adding a key called picture to  the notification payload, we can
display image on android notification.

This reverts commit c9ea7147.

* Support bitmap urls in large-icon

* feature(android): add support for badge count (#1)

Using Leolin's ShortcutBadger we are able to support any badge counts that are sent as part of the notifications data-payload.

* refactor(android): expand badge support (#3)

Android notification + data push notifications when the app is in the foreground only passes the data packet through, this changes it to pass the notification data too

Prevent NullPointerException if application activity is singleTop and minimized/restored from launcher icon. (#108)

In that case activity is reused and intent.getExtras() returns null.
