This is the drawing part. Beware of texture uniform. It looks a bit strange but otherwise causes some error. With "glUniform1i(loc_myTex, texID);" instead of "glUniform1i(loc_myTex, 0);", no texture is seen. void MyObject::draw() { // glBi…

Full screen mode for example, ANativeActivity_setWindowFlags(app->activity, AWINDOW_FLAG_FULLSCREEN, 0); where app is the ptr to struct android_app defined in android_native_app_glue.h.This function is the NDK version of android.view.Windo…

You have to adjust both project property and AndroidManifest.xml.

(1) put in AndroidManifest.xml(2)put android:settingsActivity="com.foo.FooSettings" in tab in foo.xml under @xml(3)write foo_settings.xml and string.xml then put them into @xml and @value respectively.(4)write Java codes using addPreferenc…

EGL is only supported after android-9, that is, OS 2.3.1 Gingerbread.

glEnable(GL_LIGHTING); glEnable(GL_LIGHT0); consumes 64Kbytes more than glDisable(GL_LIGHTING); glDisable(GL_LIGHT0); in top RSS. The difference looks very small. :)

The order of gl-functions in loadTex is critical. typedef struct TextureInfo_ { int width; int height; int pixelSize; int colorType; // int algnType; // 0=unsigned char, 1=uint32_t void* pPix; int id; const char* fileName; } TextureInfo; v…

You can find only 3 formats in android/native_window.h. enum { WINDOW_FORMAT_RGBA_8888 = 1, WINDOW_FORMAT_RGBX_8888 = 2, WINDOW_FORMAT_RGB_565 = 4, }; But actually, it has others. When you set up the attributes like this const EGLint attri…

getBuffer returns the pointer to the mmapped image of the asset. openFileDescriptor returns the file descriptor to the mmapped image of the asset. fdopen(file descriptor) returns the pointer to the WHOLE package(.apk).
