A wired issue of MediaPlayer on Android

-
Background Our application needs to play mp3 files served by our server. What we used to do is just using MediaPlayer to play that URL. However, there are more and more customers complaint about Music playing being cut off quite frequently. So I had to dig into legacy codes to find out the reason. Reproduce From existing codebase, I could tell our app respects MediaPlayer's   OnErrorListener   and if MediaPlay throw out any Error, app will try to catch them and recover. Unfortunately, we did not receive any exceptions for this part according to our Fabric crashlytics report. Besides that, this bug is not really easy to reproduce.   I knew it must be caused by user's network issue. So I tried Charles proxy and using its throttling feature.

So when we found "Hooks" folder what we can get is like this:    ONLY ONE "UPDATE" . If you open it you will found quite simple codes:    So check GitlabUpdate in ../lib/  And if you change the codes to exit with "1", all the push request will be rejecte...

Problem when using Jackson json parser in Android.

-
I really like to use Jackson library to parse json string. Just now met a problem org.codehaus.jackson.JsonParseException: Illegal unquoted character ((CTRL-CHAR, code 10)): has to be escaped using backslash to be included in string value The reason is my string contains some newline symbols. Then actually the string is not "valid" or "formatted" Json .  Finally I found one quick solution . try { JSONObject b = new JSONObject ( decodedPayload ); decodedPayload = b . toString (); } catch ( JSONException e ) { e . printStackTrace (); } That JSONObject can formatted that unformatted json string . Might be there are some other better solution.
