By declaring the OpenGLĮS 2.0 API as a requirement in your manifest, you can use that API version as a default, checkįor the availability of the 3.x API at run time and then use OpenGL ES 3.x features if theĭevice supports it. The OpenGL ES 3.x API is backwards-compatible with the 2.0 API, which means you can be moreįlexible with your implementation of OpenGL ES in your application. If your application is exclusively forĭevices that support OpenGL ES 3.0, you can also specify this in your manifest: Installed on devices that do not support OpenGL ES 2.0. OpenGL ES, you must declare that requirement by adding the following settings to your manifest asĪdding this declaration causes Google Play to restrict your application from being
OPENGL 4.3 AND CARDS ANDROID
Starting with Android 5.0 (API level 21). Version 3.0 is available starting with Android 4.3 (API level 18). android.opengl - This package provides the interface to the OpenGL ES 3.0/3.1.Interface to OpenGL ES 2.0 and is available starting with Android 2.2 (API level 8). android.opengl - This package provides a static interface to the OpenGL ESġ.0/1.1 classes and better performance than the package.Once you have established a container view for OpenGL ES using GLSurfaceView and GLSurfaceView.Renderer, you can beginĬalling OpenGL APIs using the following classes: Respond to changes in the GLSurfaceView container. This method when the device changes from portrait to landscape orientation.
onSurfaceChanged(): The system calls this method when the GLSurfaceView geometry changes, including changes in size of the GLSurfaceView or orientation of the device screen.Use this method as the primary execution point forĭrawing (and re-drawing) graphic objects. onDrawFrame(): The system calls this method on each redraw of the GLSurfaceView.Use this method to performĪctions that need to happen only once, such as setting OpenGL environment parameters or Method once, when creating the GLSurfaceView. onSurfaceCreated(): The system calls this.The GLSurfaceView.Renderer interface requires that you implement the
Separate class and attach it to your GLSurfaceView instance using You must provide an implementation of this interface as a GLSurfaceView.Renderer This interface defines the methods required for drawing graphics in a GLSurfaceView. Implement the touch listeners, as shown in OpenGL training lesson, Touch screen events, you should extend the GLSurfaceView class to This class by creating an instance of GLSurfaceView and adding your OpenGL API calls and is similar in function to a SurfaceView.
GLSurfaceView This class is a View where you can draw and manipulate objects using
OPENGL 4.3 AND CARDS HOW TO
Understanding how to implement these classes in an activity should be your first objective. If your goal is to use OpenGL in your Android application, Graphics with the OpenGL ES API: GLSurfaceView and There are two foundational classes in the Android framework that let you create and manipulate This topic focuses on the Android framework interfaces. If you are familiar with J2ME JSR239 specification, be alert forĪndroid supports OpenGL both through its framework API and the Native Development The specific API provided by the Android framework is similar to the J2ME JSR239 OpenGL ES API,īut is not identical. To see what version of OpenGL the device supports. Want to use 3.0 features if they're available, you should check at run time If you specify that a lower-level version is required but you OpenGL ES 3.0 is required, you can be sure that that version will be present Implementation of this graphics pipeline. The OpenGL ES 3.0 API unless the device manufacturer provides an Regardless of the Android platform version, a device cannot support
