catch all types of errors from whole application Android

Question

I have a big Android application and I have a requirement to log all types of errors that could happen in my Application including "Out of memory" etc. Is it possible to accomplish?

I can use

try {

} catch(throwable t) {

}

but adding a whole code to try/catch sounds bad. And how can I catch an errors like "out of memory"?

If it is out-of-memory how does Android throws an Exception? ;) — Enzokie, Jan 26 '17 at 06:22
Actually my first comment is sarcasm. Btw all necessary Exceptions are defined in the Class/Methods therefore you know what to catch. And yeah using a generic exception e.g. `catch(Exception e)` is a bad idea. — Enzokie, Jan 26 '17 at 06:31

To tracking crash reports best way is using 3rd party libraries like Fabric or firebase(google). If you cannot use like this libraries, you can try this.

public class MyActivity extends Activity implements Thread.UncaughtExceptionHandler{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {
        if(ex.getClass().equals(OutOfMemoryError.class))
        {
            try {
                android.os.Debug.dumpHprofData(fileName);
            }
            catch (IOException e) {
                e.printStackTrace();
            }
        }
        ex.printStackTrace();
    }
}

Why not simple replace `e.printStackTrace();` with `FirebaseCrash.report(e);` ie — Vlad, Dec 13 '17 at 20:10

yes exactly it is possible. You can write a parent activity and handle exceptions globally like in this example. After that You can use Google analytics, Crashlytics to view your daily reports of crashes etc

So I need to create a parent to each activity and it will catch all types of exceptions? Can I do it once in Application class for example? – Rainmaker Jan 26 '17 at 06:37
possible in application class, or you need only one parent activity, all other activities in your app would be inherited from that parent or base activity. – Junaid Hafeez Jan 26 '17 at 06:38

Best way is to include analytics.

please refer this. crashlytics is a library that can notify almost all problems. Try it.

Looks like a good way, but I can not use another libraries in my App. – Rainmaker Jan 26 '17 at 06:31
