Cannot run the android example on Android 5.1.1#74

The android example APK can be successfully compiled and installed (except that adb -g option is not recognized), however, at launch it shows "Failed" without showing any camera view.

Device is a Nexus 6 with Android 5.1.1.

This is what I have in WORKSPACE

# Uncomment and update the paths in these entries to build the Android demo.
android_sdk_repository(
    name = "androidsdk",
    api_level = 22, 
    build_tools_version = "22.0.1",
    # Replace with path to Android SDK on your system
    path = "/home/victor/Android/Sdk/",
)
#
android_ndk_repository(
    name="androidndk",
    path="/home/victor/Downloads/android-ndk-r10e",
    api_level=21)

    Had a similar issue but was related to the fact that the example is looking for a specific 480x320 camera preview size, see:
    https://github.com/tensorflow/tensorflow/blob/master/tensorflow/examples/android/src/org/tensorflow/demo/CameraConnectionFragment.java#L231

    Just changed that line to: if (option.getHeight() > 320 && option.getWidth() > 480) and it worked.

    Yes, the intention was to pick a size larger, but not too much larger (for performance reasons), than the 224x224 input of the Inception model bundled with the demo. There's a fix incoming that will pick a size dynamically.
