ACRA is a library enabling Android applications to automatically post their crash reports to a report server. It is targeted to android applications developers to help them get data from their applications when they crash or behave erroneously. A crash reporting feature for android apps is native since Android 2.2 (FroYo) but only available through the official Android Market (and with limited data).
Annotation-triggered method call logging for your debug builds
Hugo is a small Android library (and annotation processor plugin) that automatically logs method calls, parameters, return values, and execution time for methods annotated with @DebugLog. Instead of manually adding logging statements everywhere, you simply annotate a method and Hugo injects the logging at compile-time in debug builds, keeping release builds clean.
