Running android emulator on travis-ci and Push .apk file

I have a problem to push apk file on emulator Android with travis.

This is my config file.

script:
 - adb install -r $TRAVIS_BUILD_DIR/last-app-version/myapp.apk

Travis start the process to install apk and i get this in console.

[100%] /data/local/tmp/myapp.apk

/home/travis/build/last-app-version/myapp.apk: 1 file pushed. 3.7 MB/s (10766791 bytes in 2.768s)

pkg: /data/local/tmp/app-staging-release.apk

After awhile i get this error.

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself. Check the details on how to adjust your build configuration on: http://ift.tt/1Z1UeL8 The build has been terminated
