Its value should be the root of the Android SDK. The Android NDK must also be installed under the root, in the default `ndk-bundle` subdirectory. 13 | - Run `ant compile-templates`. This will take 1-2 minutes. 14 | - Run `ant aar`. This will produce an `lwjgl.aar` file in the `bin/android/` folder. 15 | - Copy `lwjgl.aar` to the `android-test` repository, in the `lwjgl` folder. 16 | 17 | Build instructions for the Android demos: 18 | 19 | - Open the root in Android Studio. 20 | - Wait for gradle synchronization and indexing to complete. 21 | - Build the project. 22 | - Connect a platform 24 compatible device, either via USB or Wi-Fi. 23 | - Launch either the `gears` or `hellovulkan` run configurations. (shortcut: `Alt+Shift+F10`) 24 | 25 | Installation of Vulkan validation layers: 26 | 27 | - Create a JNI library folder for the target architecture. For example: 28 | * `hellovulkan/src/main/jniLibs/arm64-v8a/` or 29 | * `hellovulkan/src/main/jniLibs/armeabi-v7a/` 30 | - Copy the shared libraries from the corresponding folder in the Android NDK. For example: 31 | * `/ndk-bundle/sources/third_party/vulkan/src/build-android/jniLibs/arm64-v8a/` or 32 | * `/ndk-bundle/sources/third_party/vulkan/src/build-android/jniLibs/armeabi-v7a/` 33 | - Set the `VALIDATE` variable to `true` in `HelloVulkan.java:53` 34 | -------------------------------------------------------------------------------- /gears/src/main/java/org/lwjgl/demo/android/gears/MainActivity.java: -------------------------------------------------------------------------------- 1 | package org.lwjgl.demo.android.gears; 2 | 3 | import android.opengl.*; 4 | import android.os.*; 5 | import android.support.v7.app.*; 6 | 7 | import org.lwjgl.egl.EGL; 8 | import org.lwjgl.egl.*; 9 | import org.lwjgl.opengles.*; 10 | import org.lwjgl.system.*; 11 | 12 | import java.lang.reflect.*; 13 | 14 | import javax.microedition.khronos.egl.EGLConfig; 15 | import javax.microedition.khronos.opengles.*; 16 | 17 | import static org.lwjgl.egl.EGL10.*; 18 | import static org.lwjgl.opengles.GLES20.*; 19 | import static org.lwjgl.system.APIUtil.*; 20 | 21 | public class MainActivity extends AppCompatActivity { 22 | 23 | private Gears gears; 24 | 25 | private GLSurfaceView glView; 26 | 27 | @Override 28 | protected void onCreate(Bundle savedInstanceState) { 29 | super.onCreate(savedInstanceState); 30 | 31 | glView = new GLSurfaceView(this); 32 | glView.setEGLContextClientVersion(2); 33 | glView.setRenderer(new GLSurfaceView.Renderer() { 34 | @Override 35 | public void onSurfaceCreated(GL10 gl, EGLConfig config) { 36 | GLES.createCapabilities(); 37 | 38 | /*APIUtil.APIVersion version = apiParseVersion(eglQueryString(eglGetCurrentDisplay(), EGL_VERSION)); 39 | EGLCapabilities caps = EGL.createDisplayCapabilities(eglGetCurrentDisplay(), version.major, version.minor); 40 | 41 | System.out.println(caps); 42 | Field[] fields = caps.getClass().getDeclaredFields(); 43 | for (Field field : fields) { 44 | try { 45 | if (field.getType() != Boolean.TYPE || !field.getBoolean(caps)) 46 | continue; 47 | System.out.println(field.getName()); 48 | } catch (IllegalAccessException e) { 49 | e.printStackTrace(); 50 | } 51 | }*/ 52 | 53 | gears = new Gears(MainActivity.this.getResources()); 54 | } 55 | 56 | @Override 57 | public void onSurfaceChanged(GL10 gl, int width, int height) { 58 | gears.reshape(width, height); 59 | } 60 | 61 | @Override 62 | public void onDrawFrame(GL10 gl) { 63 | float sin = (float) Math.sin(System.currentTimeMillis() / 1000.0); 64 | 65 | glClearColor(0.2f, 0.4f, sin * sin, 1.0f); 66 | glClear(GL_COLOR_BUFFER_BIT); 67 | 68 | gears.draw(); 69 | gears.idle(); 70 | } 71 | }); 72 | 73 | setContentView(glView); 74 | } 75 | 76 | } 77 | -------------------------------------------------------------------------------- /.idea/misc.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | 6 | 7 | 19 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 46 | -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @if "%DEBUG%" == "" @echo off 2 | @rem ########################################################################## 3 | @rem 4 | @rem Gradle startup script for Windows 5 | @rem 6 | @rem ########################################################################## 7 | 8 | @rem Set local scope for the variables with windows NT shell 9 | if "%OS%"=="Windows_NT" setlocal 10 | 11 | @rem Add default JVM options here.
