How to debug app when it's killed

Question

My app has a bug on certain activities: when it restarts (when it\'s killed and then opened again with multitasker), it crashes. I assume it has something to do with my sing

Answer 1

You can add the following code to the onCreate() method of your main activity:

    android.os.Debug.waitForDebugger();

This will pause your app till a debugger is attached to the process.

Then :

• Run your app
• Put your app in background (say, with the home button)
• Kill the process or use an app like MemoryPump to fill the RAM and have your app killed by Android
• Switch back to your app with the multitask pan (the app will start and wait for the debugger)
• Attach your android studio debugger to you app (icon in the Android Studio toolbar somewhere between the 'run app' icon and the 'stop application' icon)
• Debug your app
