## 5.2.1 Android platform cross-compiling
|

|

Compiling the Android library requires the ndk environment, and the default script is compiled using android-ndk-r10d.
|
||||
Compiling the Android library requires the ndk environment, and the default script is compiled using android-ndk-r16b. Both android-ndk-r16b and android-ndk-r25c are verified. The former applies to sdks below android 14, and the latter applies to sdks above android 14.
|
||||
|
||||
The download path for r10d ndk can be found in the build/android/ndk_links.md file in the source directory.
|
||||
Take the r16b ndk for example:
|
||||
|
||||
Unzip the downloaded ndk to /home/pub/ndk/android-ndk-r10d, or manually modify the ANDROID_NDK variable path of the env_setup.sh script in the build/android/ directory.

The download path for r16b ndk can be found in the build/android/ndk_links.md file in the source directory.

|
||||
|
||||
Go to the build/android/arm/ directory, run the make-Android.bash script to generate the Makefile for compilation, and run make –j16 to compile.
