Android Studio - failed to start adb

Question

I recently started learning android programming using android studio but every time I open the emulator and drag an apk to the emulator it says:

failed to start adb - Check settings to verify your chosen adb path is valid

as shown in the link below.

How can I fix this?

PS: Sorry for my English.

Answer 1

Step1 : Goto your Emulator settings

Step2 : General -> "Use detected ADB location" option , disable this option and select folder path for adb.exe which is ideally (windows) is c:\users"loginuser"\AppData\Local\Android\sdk\platform-tools\

This option worked for me !!

Answer 2

I got the same error, and for me, it occured because I was trying to install an APK built for ARMv7 on the emulator, which requires an x86 build. Does your build process create separate builds as well? If so, just check if you're installing the APK meant for the correct architecture!
