Process 'command '**/ndk-build.cmd'' finished with non-zero exit value 1

What went wrong:
Execution failed for task ':library:compileReleaseNdk'.
> com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'E:\android-ndk-r10e\ndk-build.cmd'' finished with non-zero exit value 1

在ndk编译的时候出翔了，调用ndk_build.com 失败，看看你的ndk里面有没有这个ndk_build.cmd.
解决方法：下个最新的ndk就好了。
