Android

Note: At this moment, our publication is being reviewed by Maven. Once published, source code dependency will be changed to AAR dependency.

• Add bridge specification dependency
• Download gcanvas source, add below line to your build.gradle: compile project (':android:bridge\_spec')
• Implement IGBridgeModule interface. The interface should build bridge between GCanvas C++ rendering engine and your Javascript runtime environment. Check comments of the interface for more details. You can extend from an abstract class named 'AbsGBridgeModule'. We strongly recommend implements your bridge by composite implementation.
• Implement interfaces with prefix IJSCallbackXXX. These interfaces are used for data communicating between Javascript and native.
• Inherit from GTextureView. This stage is optional, depending on how your runtime communicates between native and Javascript, but an OpenGL-renderable view is necessary.

• Add Cocoapods dependency Add this pod to your Podfile and run pod install to install: pod 'GCanvas'
• Export module and methods of GCanvas
  • Implement protocol GCanvasModuleProtocol in your bridge which you used, such as Cordova
  • Implement protocol GCanvasViewPortocol in your bridge as a component which contains a GLKViewas display view of OpenGL ES.
  • Export module to Javascript in your custom bridge For export module, Weex and ReactNative supply the method WX\_PlUGIN\_EXPORT\_MODULE and RCT\_EXPORT\_MODULE()
  • Export method to Javascript in your custom bridge For export method, Weex and ReactNative supply the method.
    • Weex WX\_EXPORT\_METHOD\_SYNC, synchronous method WX\_EXPORT\_METHOD, asynchornous method
    • ReactNative RCT\_EXPORT\_BLOCKING\_SYNCHRONOUS\_METHOD , synchronous methodRCT\_EXPORT\_METHOD, asynchornous method

There may be different ways in bridges. But your bridge must support export asynchornous and synchronous method both for javascript call native method. And you must implement Export method list to ensure GCanvasworks well with your bridge.
