No debuggable processes in logcat when phone detected by Android studio

Question

Everyone!

I got so confused by android studio. when I plug in my phone to debug apps, logcat can detect my phone, but I can not choose process. It said "no debuggable processes",not common "no debuggable applications".

My phone is samsung s5 (android 6.0),rooted.

Any ideas?

Thanks!

Solution 1

I had a similar issue, when I was building an app, I could select the device in Logcat, but not the process. (same message, "No Debuggable Processes")

The reason: I was building my app in release, then, when I changed the build variants to debug, I was able to select the process.

Solution 2

You need to enable adb integration, just go to Tools-->Android-->Check Enable ADB Integration

It was a default feature a few versions ago but now it's disabled by default

Solution 3

In my case, using Android Studio 3.1.3, I had to enable "Use libusb backend" checkbox at File-->Settings-->Build, Execution, Deployment-->Debugger

Solution 4

This happens time to time, try these three options in any order:

1. Restart Android Studio ( preferably with invalidated caches as well )
2. Restart your phone
3. Deactivate and reactivate usb debugging

Solution 5

one of the reasons is that your application is marked as not debuggable in the build.gradle file

buildTypes{
    release{
        debuggable false
    }
}

another reason maybe you did not allow ADB integration. You should have Tools->Android->Enable ADB Integration active

What about the cable ? There are cables out there, that have only power transfer capability..

[kimichang]

I can use adb in cmd console with the same cable,it works well.so.... I don't know the root cause about this phenomenon.

[DzefersonS]

I don't know then. Maybe you didn't do 1 important thing - when you plug your phone in, when you pull down that little menu in it you should see usb file transfer. If not yet done, select "transferring media files" so it works.

[kimichang]

I can transfer file correctly.because of my reputation on this web,i can not upload picture. or you can see the phenomenon.

[DzefersonS]

That is pretty sad. If you could explain what you did overall I could try helping you a bit more.

[kimichang]

I got the answer,maybe it can only debug the app that in your project.i want to debug others' app via attache process. Thanks a lot! you are so kind!

"Restart Android Studio" worked like a charm for me.

[E J Chathuranga]

this should be the answer. +1

[Louis]

Indeed this was not re-enabled by default for me as well

[Hong]

Great tip. I found that I had to use Task Manager to kill process monitor.exe running in the background to restore the normality.

[Zinc]

Yes, they removed it in last Android Studio version. Go to File-->Settings-->Build, Execution, Deployment-->Debugger and ensure that the Logcat output options are checked

Worked for me using a Google Pixel 2. Thanks!

[Adam]

This setting is not where it is specified above. I have 3.1.3 installed and the setting does not exist in that window.

[Antonio Papalillo]

After reading this answer I set "debuggable true" in a custom signed debug variant and it worked. Thanks!

[haggy]

This was exactly my issue. Thanks!

[Aman Goyal]

after tried all these solutions its not working for me.

[JohnyTex]

Note that debuggable may be set to true in release as well. Optional but maybe not recommended depending on you application.

[Miller Go Dev]

You saved my life! A little update to this answer, on newer versions of Android Studio, you should go to: Android Studio -> Preferences -> Build, Execution, Deployment -> Debugger

[aB9]

Doesn't work on mac though. Will give you an error when you try to debug the app. stackoverflow.com/questions/57770464/…

[JCarlosR]

Great! I didn't know I have to set debuggable true explicitly in the build.gradle file.

[Cedriga]

Best answer. It works for me. Thanks

[FerDensetsu]

Sweet! Thank you

[abbasalim]

wooooow this worked for me, after One week search :x
