Android-Runtime

Contains the source code for the NativeScript's Android runtime. The android-runtime is a main component used in NativeScript.

Main Projects

The repo is structured in the following projects (ordered by dependencies):

• android-metadata-generator - generates metadata necessary for the Android Runtime.
• android-binding-generator - enables Java & Android types to be dynamically created at runtime. Needed by the extend routine.
• android-runtime - contains the core logic behind the NativeScript's Android Runtime. This project contains native C++ code and needs the Android NDK to build properly.
• android-runtime-testapp - this is a vanilla Android Application, which contains the tests for the runtime project.

Helper Projects

• android-static-binding-generator - build tool that generates bindings based on the user's javascript code
• android-binding-generator-tester - contains the tests for the binding-generator project.
• build/project-template - this is an empty placeholder Android Application project, used by the NativeScript CLI when building an Android project.

Build Prerequisites

Following are the minimal prerequisites to build the runtime package.

• Install the latest Android Studio .
• Install Android API Level 22, 23, 24, 25 from Android Studio -> Tools -> Android -> SDK Manager
• Android NDK 12b - NDK Archives
• Download Android Support Repository through the Android SDK Manager
• Download Build Tools 25.0.2 through the Android SDK Manager.

How to build

• Run command

  Windows:

  gradlew createPackage

  Mac/Linux:

  ./gradlew createPackage

• The build process includes building of the runtime package (both optimized and with unstripped v8 symbol table), as well as all supplementary tools used for the android builds: metadata-generator, binding-generator, metadata-generator, static-binding-generator

• The result of the build will be in the dist folder.

  Note: To cut the build time in half and package only the optimized (stripped) version of the runtime package comment out 'tasks.generateRuntimeAar.execute()' in the build.gradle script.

How to run tests

• Go to subfolder test-app after you built the runtime.

• Start an emulator or connect a device.

  Note: Keep in mind the device or emulator needs to have an sdcard mounted.

• Run command

gradlew runtest
