04-28 08:25:35.699: e/androidruntime(11113): fatal exception: thread-775 04-28 08:25:35.699: e/androidruntime(11113): java.lang.nullpointerexception 04-28 08:25:35.699: e/androidruntime(11113): @ com.ritvik.weaselyclock.gcmintentservice.handlemessage(gcmintentservice.java:69) 04-28 08:25:35.699: e/androidruntime(11113): @ com.ritvik.utils.httputils$1.run(httputils.java:48) 04-28 08:25:35.699: e/androidruntime(11113): @ java.lang.thread.run(thread.java:838) edit: issue isn't methods aren't being called handler not being initialized properly.
any appreciated. thanks.
