I had this problem with Android Studio 2020.3.1, which I ran in debug mode on my phone. After a lot of test and research I realized the Android Studio 2020.3.1 has bugs and finally I installed Android Studio 4.1.3 and my problem was solved.

So if you tried all the ways :

  • Invalidate Cashes and Restart Android Studio
  • Clean Project
  • Rebuild Project
  • Kill and restart ADB
  • ...

Then it's time to change your Android Studio Version.

Try set Debugger type to "Java Only"

You can follow this way:

Run -> Edit Configuration -> Android App -> Your app module -> debugger -> set "Java Only" enter image description here

It's caused by broken Android SDK Platform-Tools 29.0.3

To solve this issue you should download platform tools 29.0.2 from (mac, win, linux). Extract it and replace platform tools inside Android SDK.

UPD: This issue has been hotfixed with platform-tools 29.0.4: https://issuetracker.google.com/140369526 Now you can update to the latest version, instead of a downgrade.

I also have same bug. No need to do rebuild,clean, restart or uninstall. Just change Run --> Edit Configuration --> Debug Type --> Change to Java. Even for Native build application change to Java. This bug is due to the latest update of lldb server.

I have the same bug, but my project doesn't have C++ code. I went to Run -> Edit Configurations -> Debug -> Debug type and set it to "Java" instead of "Auto". Maybe if you chose "Native" it will fix the problem for you.
