How do I fix "Could not connect to remote process" while trying to debug the application?

Question

I am making a android studio project and I try to debug my application.

Running the application works fine, but when I try to debug it I get this error:

Could not connect to remote process. Aborting debug session.

What can I do to fix the issue?

Solution 1

You need to restart the ADB.

kill adb.exe process.

how to restart ADB manually from Android Studio

Solution 2

Sometimes this happens when two Android-capable IDEs are opened, e.g. Android Studio and IDEA. Shutdown one of the two (or disable Android plugin in IDEA) helps.

In My case, For some reason I disabled Instant run and it has changed the Launch value from "Default Activity" to "Nothing" in "Run/Debug configurations". So always it says "Could not connect to remote process. Aborting debug session" and I was not able to debug. I enabled Instant and changed the Launch value from "Nothing" to "Default Activity" in "Run/Debug configurations" and it worked. Hope this will help some one.

(to get Run/Debug configurations, click "app" drop down and click Edit Configurations)

Check if you have selected the right Build Variant, usually "release" comes with debuggable false

Example:

 buildTypes {
        release {
            debuggable false
            ....
        }
    }

is not recommendable change release to debuggable true, just change the right variant

   debug {
        debuggable true
        ....
    }
