Where is the SimpleLock.apk for uWeave on nRF51/52?

[karanvt]

In libuweave project there is an example demonstrating communication between nRF51/52 and android client app. The Android client application is named SimpleLock.apk. But I'm not able to find it anywhere. Can anyone please share the apk or point out the path from where I can download?

git clone weave.googlesource.com/.../weave_playground_android

It is giving me error of INSTALL_FAILED_CONFLICTING_PROVIDER while installing the application to device.
