1 Development Environment Setup Mobile Visual Computing

2 Development Environment Setup Copy VCDevEnv to C:\ Install driver for your device C:\VCDevEnv\drivers Run C:\VCDevEnv\startEclipse.bat

3 Check device Command line %adb% device C:\VCDevEnv\examples\01-ogles2Tut01\shader>%adb% devices List of devices attached 0149CC device %adb% commands push pull...

4 Example programs Run program... Build Run Device tap kill restart Logging log tab

5 Own project Create new Android project Create Java classes for main types Activity oncreate onpause onresume ExampleActivity oncreate onpause onresume GLSurfaceView setrenderer Renderer onsurfacecreated onsurfacechanged ondrawframe ExampleView setrenderer ExampleRenderer onsurfacecreated onsurfacechanged ondrawframe

6 interface GLSurfaceView.Renderer public class ExampleRenderer implements Renderer { public void onsurfacecreated(gl10 gl, EGLConfig config){ // called once at setup public void ondrawframe(gl10 arg0) { // called to redraw the view public void onsurfacechanged(gl10 gl, int width, int height){ // called when geometry changes

7 integration in Activity public class GL2Ex1Activity extends Activity { private GLSurfaceView glview; /** Called when the activity is first created. public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); glview = new GLSurfaceView(this); glview.seteglcontextclientversion(2); glview.setrenderer(new ExampleRenderer()); setcontentview(glview); protected void onpause(){ super.onpause(); glview.onpause(); protected void onresume(){ super.onresume(); glview.onresume();

8 Setup OpenGL ES 2.0 Add to AndroidManifest.xml <uses-feature android:glesversion="0x " android:required="true" /> Enable 2.0 in GLSurfaceView glview = new GLSurfaceView(this); glview.seteglcontextclientversion(2);

9 JNI - Java Native Interface Extending Java with native (C/C++) code NDK Create a Java class with native methods directory jni example.cpp C++ source file Android.mk build file Setup builder for compilation

10 Java class with native methods package com.android.gl2ex1; public class Example { static { // name of native shared library System.loadLibrary("gl2ex1"); public static native void onsurfacecreated(); public static native void ondrawframe(); public static native void onsurfacechanged(int w, int h);

11 example.cpp C++ source file extern "C" { JNIEXPORT void JNICALL Java_com_android_gl2ex1_Example_onSurfaceCreated (JNIEnv * env, jobject obj) { printglstring("version", GL_VERSION); printglstring("vendor", GL_VENDOR); printglstring("renderer", GL_RENDERER); printglstring("extensions", GL_EXTENSIONS); glclearcolor(0, 0, 1, 1); JNIEXPORT void JNICALL Java_com_android_gl2ex1_Example_onDrawFrame (JNIEnv * env, jobject obj) { glclear( GL_COLOR_BUFFER_BIT); JNIEXPORT void JNICALL Java_com_android_gl2ex1_Example_onSurfaceChanged (JNIEnv * env, jobject obj, jint width, jint height) { glviewport(0, 0, width, height); Naming convention package_package_class_method

12 Android.mk build file LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := gl2ex1 # library name LOCAL_CFLAGS := -Werror LOCAL_SRC_FILES := example.cpp # source files LOCAL_LDLIBS := -llog -lglesv2 -lstdc++ include $(BUILD_SHARED_LIBRARY) setup builder...

13 Implement Renderer in native code public class ExampleRenderer implements Renderer { public void onsurfacecreated(gl10 gl, EGLConfig config){ // called once at setup Example.onSurfaceCreated(); public void ondrawframe(gl10 arg0) { // called to redraw the view Example.onDrawFrame(); public void onsurfacechanged(gl10 gl, int width, int height){ // called when geometry changes Example.onSurfaceChanged(width, height);

14 Adding menus Create a menu resource res/menu/menu.xml as Android xml Add menu items Load menu & handle events public class GL2Ex1Activity { public boolean oncreateoptionsmenu(menu menu) { MenuInflater inflater = getmenuinflater(); inflater.inflate(r.menu.menu, menu); return true; public boolean onoptionsitemselected(menuitem item) { switch (item.getitemid()) { case R.id.hello: Log.i("menu", "got hello"); return true; case R.id.test: Log.i("menu", "got test"); return true; default: return super.onoptionsitemselected(item);
