 ### Android
 
 Run:
 
 ```bash
-$ source ./android-configure NDK_PATH gyp
+$ source ./android-configure NDK_PATH gyp [API_LEVEL]
+$ make -C out
+```
+
+The default API level is 24, but a different one can be selected as follows:
+
+```bash
+$ source ./android-configure ~/android-ndk-r15b gyp 21
 $ make -C out
 ```
 
 Note for UNIX users: compile your project with `-D_LARGEFILE_SOURCE` and
 `-D_FILE_OFFSET_BITS=64`. GYP builds take care of that automatically.
