I use Install Android Package Option in Build Step

Before running the installer, I did adb devices and it's showing the emulator

+ /tmp/jenkins/tools/android-sdk/platform-tools/adb devices
15:50:37 List of devices attached
15:50:37 localhost:49651 device
15:50:37
15:50:37 [android] Installing APK file 'EM_Runtime.apk'
15:50:37 $ /tmp/jenkins/tools/android-sdk/platform-tools/adb -s localhost:49651 install -r Runtime.apk
15:50:47 729 KB/s (7369965 bytes in 9.870s)
15:50:50 pkg: /data/local/tmp/Runtime.apk
15:51:27 - waiting for device -

It's supposed to show "Succeed" which is not. I tried to run this again:
+ /tmp/jenkins/tools/android-sdk/platform-tools/adb devices

It would just restart adb.

Is it a known issue? Anyway that I could resolve it?
