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). ACRA is a great help for Android developers. ACRA's notification systems are clean. If a crash occurs, your application does not add user notifications over existing system's crash notifications or reporting features. By default, the "force close" dialog is not displayed anymore, to enable it set alsoReportToAndroidFramework to true. The user is notified of an error only once, and you might enhance the perceived quality of your application by defining your own texts in the notifications/dialogs.

LeakCanary is a reliable memory leak detection library for Android. It effectively detects leaks and narrows down the cause of each leak through its in-depth knowledge of the internals of the Android Framework. This helps developers avoid and dramatically reduce OutOfMemoryError (OOM) crashes. A memory leak is a programming error that can cause an OutOfMemoryError crash. It’s often caused by bugs related to the lifecycle of objects, and can occur fairly often in Android applications. LeakCanary helps to find and fix those leaks during development so you never have to experience another OOM crash.
