# android.useDeprecatedNdk 过期：

```c
The option 'android.useDeprecatedNdk' is deprecated.
```



# local.properties：ndk.dir过期：
```
NDK was located by using ndk.dir property.
This method is deprecated and will be removed in a future release.
If you delete ndk.dir from local.properties and set android.ndkVersion to [22.1.7171670]
then NDK at
/Users/tmk/Library/Android/sdk/ndk/22.1.7171670 will be used.
