How to create an Object with private creator (like EGLContext) under PIE?

问题

This class is defined under Android:

public abstract class EGLObjectHandle {
    private final long mHandle;

    protected EGLObjectHandle(long handle) {
        mHandle = handle;
    }


    public long getNativeHandle() {
        return mHandle;
    }

}

and also

public class EGLContext extends EGLObjectHandle {
    private EGLContext(long handle) {
        super(handle);
    }

} 

now my problem is that I want to create an EGLContext with my handle. How to do this? before I do it with the function below but it's not working anymore on PIE

  private android.opengl.EGLContext createSharedEGLContextObj(long handle) throws ClassNotFoundException, InstantiationException, IllegalAccessException, NoSuchMethodException, InvocationTargetException {
    Class<?> classType =Class.forName("android.opengl.EGLContext"); 
    Class<?>[] types = new Class[] { long.class };
    Constructor constructor=classType.getDeclaredConstructor(types);
    constructor.setAccessible(true);     
    Object object=constructor.newInstance(handle);
    return (android.opengl.EGLContext) object;
  }

I need an EGLContext because I need to pass it to a procedure who require an EGLContext parameter, like for example: createEgl14( android.opengl.EGLContext sharedContext)

回答1:

You pretty much can't. According to Android Restrictions they have restricted JNI and reflection to only SDK interfaces.

I think your final option is request a new feature where they will change the constructor visibility to public.
