I have a strange issue I'm experiencing when developing an app for Android. I'm trying to debug my application using my phone (a Oneplus One), Android Studio and ADB. Everything works as normal except that when I start an activity that already has a breakpoint set in Android Studio, it crashes with no log output. This happens both when the activity is the launch activity and when I'm starting one with an intent.
As you can imagine, this is incredibly irritating since I have a bug in my onCreate() method that I want to break in.
I have tried adding the line Debug.waitForDebugger() to the bit of code above the breakpoints but this doesn't help.
I haven't added any code to this question because this error is independent of the code. It happens with multiple projects and Activities. I don't have another Android phone to test it on so can't check that. Has anyone else experienced this and/or found a fix?
Thanks in advance.
EDIT: Added an example of code. This code does not crash when a breakpoint is not set, neither does the breakpoint need to be in this bit of code for the crash to occur. This is just the code I'm trying to debug, behaviour of which would be impossible to fix without knowledge of my server back-end, so I'm not asking for help with that.
