“adb install” returns error: protocol fault (no status)

Question

I have created and ran a couple of android emulators, now I\'d like to install application on them. Here is the story of me trying it a couple of times:

$ ad         


        

Answer 1

I ran into it because there was more than one ADB device connected.

Disconnecting all but the device I was working with worked for me.

Answer 2

“adb install” returns error: protocol fault (no status) :

Solution is

Goto \platform-tools using Terminal and execute below commands

set ADB_TRACE=1
adb start-server

To remove emulator from list of ADB Devices :

Open "Android Virtual Device Manager" -> Select the Emulator which you want to delete -> click on Delete button.

Answer 3

For me it turned out to be an outdated ADB service (outdated Platform-tools).
It still could be an outdated driver, but since the drivers aren't updated most of the time, make sure you've installed the latest version of your Android SDK Platform-tools via the SDK Manager:

I also read that the problem could appear, when you install the Android Studio. Then you have to disable the ADB integration via "Tools -> Android" (uncheck). After that, restart you adb server by using adb kill-serveror simply restart your computer.
