The reason is simple: in res/layout/ directory, main.xml file is defined. You may encounter some errors while compiling the application with Ant: Compile and install the final San Angeles application.Īs this application uses OpenGL ES 1, AVD emulation will work, but may be somewhat slow!.Go to the San Angeles sample directory. ![]() To test this demo, you need to follow the same steps: Have a go hero – compiling san angeles OpenGL demo You can find more information by visiting one of the author’s page. It has been later ported to OpenGL ES and reused as a sample demonstration in several languages and systems, including Android. San Angeles is a coding demo created in 2004 for the Assembly 2004 competition. HelloJni sample is a little bit… let’s say rustic! So what about trying something fancier? Android NDK provides a sample named San Angeles. A simple bash script with Ant is enough to make it work! HelloJni is the main Activity class name concatenated to the main package.īecause Android SDK, NDK, and their open source bricks are not bound to Eclipse or any specific IDE, creating an automated build chain or setting up a continuous integration server becomes possible. Command parameters passed in step 8 come from the Android manifest: is the package name and. JNI is a standard framework that allows Java code to explicitly call native C/C++ code with a dedicated API.įinally, we have launched HelloJni on our device from an Android shell ( adb shell) with the am Activity Manager command. Both sides of the application, the native and the Java one, communicate through Java Native Interface. This library simply returns a character string to the Java part of the application on request. We have also compiled our first native C library (also called module) using the ndk-build command. We have compiled, packaged, and deployed an official NDK sample application with Ant and SDK command-line tools. Finally, look at your development device. ![]() Command parameters come from the Android manifest: Command am allows to start Android activities, services or sending intents (that is, inter-activity messages) from command line. To do so, use am, the Android Activity Manager.
