Relaunch your Android app when it crashes
public class App extends Application {
@Override
public void onCreate() {
super.onCreate();
//if you have a DEFAULT activity defined
Frankenstein.register(this);
}
}If you do not have a default activity defined:
//specific the intent you want to relaunch when the app crashes
Frankenstein.register(this, new Intent(this, LaunchActivity.class));Make sure to call this after setting up any crash reporting software such as Fabric. Now later, if your app crashes, your LaunchActivity will be launched
Android Studio clears LogCat when the app is restarted, so, you might want to surround the registration with a non-debug check:
if (!BuildConfig.DEBUG) {
Frankenstein.register(this);
}It is great to keep things mostly stateless in an Android app, but there are times when you need to load something important when the app launches, and keep a reference to that thing throughout the life of the app. If you application crashes, you will lose all static memory, which is typically where these things reside. There are of course other ways of handling this problem, such as checking the overall state of the app in the onResume of a base activity, or something similar, but this is a quick solution to this issue and allows you to not have to care about the base activity.
Only use this if you really do need it
It is important to note that if the app were to crash in the background, it would relaunch into the foreground, which could be frustrating for your user. The sample shows how to counteract this using another library, Lifeline. All this setup takes place in the App class.
