我正在尝试在Ubuntu中“制作”一个项目，我的.bashrc（在我的主目录中）包含有效的NDK和SDK路径：
export PATH=${PATH}:/home/user/Downloads/android-sdk-linux/tools
export PATH=${PATH}:/home/user/Downloads/android-sdk-linux/platform-tools
export PATH=${PATH}:/home/user/Downloads/android-ndk-r10e
export ANDROID_HOME=/home/user/Downloads/android-sdk-linux
export ANDROID_EMULATOR_FORCE_32BIT=true
...但是Ubuntu仍然显示 'Could not find ndk-build. Please install Android NDK' and Could not find android. Please install android SDK
有谁知道如何解决这个问题？任何输入都表示赞赏 .
