Error: Gradle: Execution failed for task ‘:mytask’ > A problem occurred starting process ‘command ‘jni/ndk-build.cmd”
这是win7打开android程序出现的问题，解决方法：打开build.gradle，找到“commandLine”这行，把commandLine ‘ndk-build’, ‘-C’, file(‘jni’).absolutePath改为commandLine ‘cmd’, ‘-C’, file(‘jni’).absolutePath。
打开android程序出现问题：can’t start Git.解决办法，file->setting->Version Control->Git.在Path to Git executable中写入：C:\Users\hongbinwang\AppData\Local\GitHub\
