Right-click on the project name and choose Android tools > Add Native Support.

Uncheck Create activity and click Finish.

Uncheck Create custom launcher icon and click Next.

Change the Minimum Required SDK to API 9: Android 2.3 (Gingerbread).

Pick an Application Name (in this tutorial we are using SimpleNativeGL as a name).

Create a new Android application ( File > New > Android Application Project).

Finally click OK.įrom the Java perspective, let's create the new project: As a general rule, you should always be extremely cautious when using this option, since Eclipse does not move the project to the trash, but rather deletes it completely. If you copied the files into the workspace when importing the project, in the next window check the box Delete project contents from disk (cannot be undone), and verify that you're deleting the correct project. If you imported the project already, right-click on the project name in the Project Explorer pane, and click delete.

To learn how to create a project from scratch, let's go through the steps necessary to create the project we imported in the previous section. Try tapping the device display, and slide your finger along the display the solid color that is displayed should vary depending on the touch location. In the Android tab, make sure that the version selected is at least Android 4.0.3 (API 15):īuild the project (right-click SimpleNativeGL > Build Project), and run it on your device (right-click SimpleNativeGL > Run As > Android Application). In the Project Explorer, right-click on the project folder and choose Properties. Sometimes the project might be imported with the wrong Android version. Select Project Type to be Makefile project and Toolchain to be Android GCC.

The files and folders within the red rectangle are the ones you just imported, others were generated during the Import operation.Īs this is a native project, select the C/C++ perspective.īy default all Android projects are Java projects, let's convert ours to native by right-clicking the project in Package Explorer and selecting New > Convert to C/C++ Project. Open the project in the Package Explorer. In this case, we'll use the name SimpleNativeGL. Its location may vary depending on the operating system, could be under Refactor). then you should rename the project (right-click the project and find the Rename option.

Start by importing /tutorials/SimpleNativeGL project. Let's start the first GL application by importing an existing project to Eclipse. For the latter, we will follow similar steps to those described in Creating a NativeActivity, in case you need a more in-depth overview. We first show how to import an existing native GL project into your workspace, and then we show you how to create the same project from scratch. We also cover how to handle various Android events in a native program. From now on, we'll use GL as a shorthand for OpenGL ES 2.0. For 3D graphics, there are other tutorials available, as well as the NativeGlobe example provided in CodeWorks for Android. In this section, we only cover 2D graphics using OpenGL ES 2.0. OpenGL ES provides a fast way to display the camera images, possibly after some image processing, and allows building simple user interfaces.
