Android Studio provides a debugger that lets you do the following and more:
- Select a device to debug your app on.
- Set breakpoints in your Java, Kotlin, and C/C++ code.
- Examine variables and evaluate expressions at runtime.
Application Process (Java) Debugging
Flash your build to a device or emulator.
Set breakpoints in your Java or Kotlin code.
Click Run > Attach Debugger to Android Process. Uncheck Native
Debugger.
Select your device, select the process, and click Attach.
Hit the breakpoint in your code.
System Process (C++) Debugging
Flash your build to a device or emulator.
From inside path/to/repo/checkout, run adb root. Only one emulator
or device can be running.
Set breakpoints in your native code.
Click Run > Attach Debugger to Android Process.
Check Show system processes.
Select your device, select the process, and click Attach.
