Huawei, logcat not showing the log for my app?

OK, logcat is showing system logs but it is not showing application log on my Huawei Ascend. If I switch to another device such as my Galaxy Nexus or Nexus 7 then for the same app (same APK even) log is displayed.

The Huawei Ascend is running Android 4.1.1, it has USB debugging switched on in developer options. This occurs for logcat run from either the command line or from IntelliJ. And I'm making sure that the correct device is selected - in fact I'm only plugging a single device in at a time. I've tried restarting adb, clearing it's buffer etc

I can see that the app is starting on the Huawei, I even get system logs showing that the Activity has started. But unlike on the other devices I get no app log in the Activity#onCreate (or from anywhere else).

08-08 20:55:44.050: INFO/WindowManager(431): Switching to real app window: Window{41ae8780 au.com.xandar.wirelesstiming.timekeeper/au.com.xandar.wirelesstiming.timekeeper.TimeKeeperActivity paused=false}
08-08 20:55:44.180: INFO/ActivityManager(431): Displayed au.com.xandar.wirelesstiming.timekeeper/.TimeKeeperActivity: +387ms

How can the application log not be getting delivered?

OK, since I had another Huawei Ascend I ran into the same problem. This time I have the exact answer. Follow these instructions (from denispyr's answer on Why doesn't logcat show anything in my Android?)



and you will see a hidden menu. Go Project Menu / Background Setting / Log setting and define the log availability (log switch) and level (log level setting).

And then make sure you restart your phone.

Please note this probably only applies to Huawei phones.
