Requirements

The following dependencies are required to build the library from source.

• Windows

  • Android Studio.

• Android

  • Termux
  • Android SDK
  • Android NDK

Building

• Android

  Download the Android SDK and Android NDK.

  # install openjdk-17
  pkg install openjdk-17
  
  # install gradle
  pkg install gradle

  Add a local.properties file to the root of the project as below

  # modify the local.properties file
  # although ndk.dir has been deprecated, but it still works
  sdk.dir=/path/to/android-sdk
  ndk.dir=/path/to/android-ndk
  # for example:
  sdk.dir=/data/data/com.termux/files/home/android-sdk
  ndk.dir=/data/data/com.termux/files/home/android-ndk-r23b

  Execute the gradle build command to start building the android app, when building for the first time, the below error will occur. this is because the gradle plugin will download a corresponding version of aapt2-7.0.3-7396180-linux.jar, we need to replace it.

  

  Replace the aapt2 in aapt2-7.0.3-7396180-linux.jar with aapt2-7.0.3-7396180-linux.jar or Making AGP jar file you need sdk-tools/build-tools/aapt2

  # aapt2 is inside the jar file(aapt2-7.0.3-7396180-linux.jar)
  # because the aapt2 is x86_64 architecture not aarch64, so we need to replace it
  # execute the find command to search aapt2-xxx-linux.jar, then replace it
  cd ~/.gradle
  find . -type f -name aapt2-*-linux.jar
  cp /path/to/aapt2-7.0.3-7396180-linux.jar /the/output/from/find/command

  

  If an error occurs during the build app, this may be a network problem, please execute the gradle build again or execute the gradle build --info for more information.
