Unable to run "ANY" react native example project

Question

I am trying to run the UIExplorer project on Ubuntu 14.04. I have installed SDK and NDK. I am able to run usual projects of react native(the one's I create), but not the Examples from Official Repo.

export ANDROID_NDK=/home/bozzmob/android-ndk-r10e/

I am getting the following error-

Execution failed for task ':ReactAndroid:buildReactNdkLib'.

Process 'command '/home/bozzmob/android-ndk-r10e/ndk-build'' finished with non-zero exit value 2

Logs look like-

root@purvotara:~/ReactJS/native/react-native# ./gradlew :Examples:UIExplorer:android:app:installDebug
.

Seems like you're having problems with compiling native (c++) sources of react-native android. In order to start new project you should not be required to do that (no NDK setup is required) and therefore you can just try creating sample project with react-native init (see this for instructions). After that you can just copy sample app JS files to your newly created project.

If you'd still like to build framework code from source, I'd need some more details in order to help you. I'd suggest enabling verbose mode for ndk-build, then you can get back here with the output. In order to enable verbose mode you'd need to modify this file: ReactAndroid/build.gradle and add 'V=1' to args so that the code fragment I linked to looks like this:

    commandLine getNdkBuildFullPath(),
        'NDK_PROJECT_PATH=null',
        'V=1',
        "NDK_APPLICATION_MK=$projectDir/src/main/jni/Application.mk",
        'NDK_OUT=' + temporaryDir,
