Why Android Studio says "Waiting For Debugger" if am NOT debugging?

I've ran into this issue in the past and again today. In my case the problem is resolved by a device reboot. After a clean boot I can again run the application and the "Waiting for Debugger" prompt does not appear.

You can fix this issue without re-booting your device. Just go to "Android device"->"Settings"->"Developer Options"->"Select app to be debugged" / "Select debug app". It will likely be pointing to your application. Just select the option and then select "None".

Note: As mentioned, even if "None" is already selected, re-selecting "None" appears to correct the problem.

Note #2: In newer Android devices, the settings location / name might be a bit different. I.e., in my case (Android 11, Samsung) the "None" option is shown as "Nothing" instead.

Just to be clear: This is on the device, not in Android Studio (cf. very helpful comment from Regis_AG).

faster than rebooting is Just go to developer options and switch it off and on again (dont forget to check usb debugging option too), worked for me(Neuxs5).

Please try this command to disable it.

adb shell am clear-debug-app

Without restarting the device, I was able to fix this issue by going to "Developer Options" and then first "disabling" and then "enabling"-

After 8 hours on this problem I feel obliged to share the cause. My /etc/hosts was bad.

Make sure you can ping localhost and that it is defined to 127.0.0.1. AS expects to connect to localhost:8600.

1) Clear android studio cache memory from file->Invalid cache/restart.

2) After restarting the android studio please restart android emulator.

I uninstalled the app with which this issue was occurring.

Then I installed the app with debug mode.

It solved the problem. Now it is working fine.

I have the same problem. In my case I have two development environments open in the same time: Android Studio and Eclipse. After I close Eclipse and run the debug process again works well. Hope this help!

You may want to check your debugging setting in Dev Setting on your AVD. Take a look at the following picture:

I had this problem; In Android Studio I accidentally hit Run > 'Debug App' instead of Run> Run 'App' . I solved the problem. In my case I had to get the application to launch successfully in DEBUG mode. Here were my steps-

1) The android device needs to be able to connect to the development PC on port 8600. This connection was being disallowed by my firewall configuration. I turned off the firewall. Once confirmed I created a firewall rule to allow connectivity between the devices on port 8600.

2) To validate that the port is available, you can go into Android Studio, Run > Attach debugger to Android Process. This will cause the android device application launched in DEBUG mode to connect to your Android Studio development PC.

3) Once the app has launched once, you can go back and Run > Run 'App' and you will no longer get the annoying screen 'WAITING for DEBUGGER'.

4) And you can also Run> Debug 'App'. The device will say "Waiting for Debugger" for a moment and then Android Studio will start up a Debugger Console and help you debug your android device app remotely!

Good luck

My PC was running low on memory and this problem appeared quite often. Fix was to free up more memory by deleting old files/apps. I notice that running emulators like Android TV tend to need a lot of memory for them to run predictably

I have already solve this problem by reboot my device. It is a device issue not android studio issue.

I fixed it by making duplicate Virtual device after wiping existing Virtual device.

Click on AVD Manager. From device actions option select "Cold Boot Now" Doing a cold boot in the emulator worked for me.

Clic and hold the Emulator's power button for 5 seconds, then clic restart.

Try again, the error should be gone

Save everything using ctrl+s or "File" -> "Save all". Go to your project directory and delete the .gradle folder then refresh window using F5. After this step, open project in Android Studio and run the application using Shift+F10 or Run -> "Run app". Then it should run in normal mode.

In my case the debug was stuck and didn't advance. So I remove the ".lldb" folder in the path "C:\Users{user}.lldb" and now is working.
