Android app crashes when trying to connect a debugger

Question

Some of them, only some of my applications are broken, when I try to connect the Android Studio debugger, I get this error:

Disconnected from the target VM, address: 'localhost:8602', transport: 'socket'

I tried restarting Windows and Android Studio and My Nexus, nothing works.

I am using the latest version of the Android SDK, Build Tools, ...

Part of the log after this failure:

Answer 1

I had the same issue on Android Studio 3.0 on Mac. The solution got this answer , basically you need to disable Instant Run (although I haven't used it):

On Mac OS X:

• Android Studio
• Preferences
• Assembly, execution, deployment
• Instantrun
• " " "...".

Answer 3

I solve the same problem a few months ago using this, please try once:

Switch to

• Tools
• Android
• enable adb integration, this must be checked when you are in debugging. try to remove and check again.
• finally restart android studio or add the moibile plug-in device.

Hope this works.
