Android Device not found by ADB tool

Question

I want to deploy android app on device. But when run 'cordova run android --device' throws error as,

ERROR: Failed to launch application on device: ERROR: Failed to install apk to device: ERROR: Failed to deploy to device, no devices found. Error: /home/inkilab/golang/src/github.com/okpatil4u/android/platforms/android/cordova/run: Command failed with exit code 8 at ChildProcess.whenDone (/usr/lib/node_modules/cordova/node_modules/cordova-lib/src/cordova/superspawn.js:135:23) at ChildProcess.emit (events.js:98:17) at maybeClose (child_process.js:756:16) at Process.ChildProcess._handle.onexit (child_process.js:823:5)

When I enlist adb devices output is as

List of devices attached emulator-5554 device

I have enabled USB debugging on my android device. So, what is the problem now?

Answer 1

it looks like you have connected only emulator. please connect or disconnect the device and you should confirm security question. Check usb cable.

Answer 2

You have to pass your device identifier in your command line like this :

cordova run android --device=emulator-5554

See, in your error trace, it try to install apk on the 'device :' <- void identifier
