Is it possible to display the log messages (which I print using android.util.Log) on screen in an Android application?
Is there any other better method
Like others have suggested, you can use log cat. If you are using the emulator or debugging a device, you can use adb logcat to view the messages. In Eclipse debug perspective, there is a window that will do that for you.
Another way, without a debugger attached, is to use the CatLog - Logcat Reader application.
