Android NDK: Could not find application project directory

ndk-build時錯誤：

Android NDK: Could not find application project directory !    
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.    
/opt/android-ndk-r10b/build/core/build-local.mk:148: *** Android NDK: Aborting    .  Stop.

解決方法：

cd 到jni目錄下（Android.mk和Application.mk在該目錄下），再ndk-build，ok

如果不行，可以試試其他方法。
