1. eXtreme eXception eXpectation

4. Crashes suck!

5. IT´S DANGEROUS TO GO
ALONE! TAKE THIS!

6. What what, what, what?

7. It ain’t nuthin’ but a code thang
Thread.setDefaultUncaughtExceptionHandler(new ExceptionHandler());

8. public class ExceptionHandler implements Thread.UncaughtExceptionHandler {
@Override
public void uncaughtException(Thread thread, Throwable ex) {
// Do things with the thread and the exception here
Troidolytics.defaultHandler.uncaughtException(thread, ex);
}
}

9. But what happens when internet
go boo boo?

10. Cache and Carry
Crash reporters cache the exception reports and send them
the first time your app is opened with internet access.

11. But da app sux!!!!1!!!!1!!!11!
What if your crash disappoints the user and they
never start the app again?

12. public class ConnectivityBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
ConnectivityManager cm = (ConnectivityManager)context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if(netInfo != null && netInfo.isConnected()){
// Send the reports here, you should probably start a service
Troidolytics.sendReports(); // #inspired
}
}
}

13. <receiver android:name="zg.troido.crashme.ConnectivityBroadcastReceiver"
android:enabled="true"
android:exported="true"
android:label="ConnectivityChange">
<intent-filter>
<action android:name="android.net.conn.CONNECTIVITY_CHANGE"
/>
</intent-filter>
</receiver>

14. It’s not only your app
that’s not responding

15. compile 'com.github.anrwatchdog:anrwatchdog:1.1.+'

16. if (!BuildConfig.DEBUG) {
new ANRWatchDog().start();
}

17. WHY DO WE NEED THIS?

18. SUPERPOWERS
grouping crashes
os version
device model
ram / cpu

19. What what, what, what?

20. Log EVERYTHING
caught exceptions,
custom messages,
variable states
} catch (Exception e) {
Crashlytics.logException(e);
ACRA.getErrorReporter().handleException(e);
}
And if you are special and want
custom logging?

21. Exporting crashes

22. WTF is... ACRA?

23. init
@ReportsCrashes(
formUri = "http://www.backendofyourchoice.com/reportpath",
formKey = "" // This is required for backward compatibility but not used
)
public class AcraApplication extends Application {
...
}

24. init
public void onCreate() {
super.onCreate();
ACRA.init(this);
}

25. WTF is Crashlytics?

26. init
get fabric plugin
include crashlytics

27. TAKEOUT
know your app
Plan-Do-Check-Adjust
stability matters
