Official documentation defines Context as such: Such classes and abstractions can be called “context-related”. You can read more on the getting started page.Īndroid SDK is full of classes that have Context as a parent class. This helps developers dramatically reduce OutOfMemoryError crashes. With its vast knowledge of the Android Framework internals, LeakCanary has a unique ability to narrow down the cause of each leak. You should check all the resources and Context-related variables used in classes that you see on the crash stack. This is a 100% proven indicator that you have a memory leak. You can check them on Google Play Consoles or read more here. Some of ANR (“Application Not Responding”) may be caused by big heap allocating and UII freezes for more than 50 – 100ms. You can read more on the getting started page.
This CI tool helps you find possible null pointer exceptions and resource leaks, as well as annotation reachability, missing lock guards, and concurrency race conditions. Infer is a static analyzer tool made by Facebook. If you notice that memory is allocated but doesn’t get deallocated in a short period of time, this is probably what we are looking for. Memory heap will be increasing and decreasing depending on the actions that the application does at the moment.
You can see how much memory your app has allocated at the moment. One such tool is the Memory Monitor. Open the bottom tab in Android Studio while the app is running on a device or emulator. Android Studio provides handy tools for profiling the performance of your app.
