This quickstart guide shows how to build and debug a simple Android App with a native library.<\/p>\n

Before you begin, please install VisualGDB 2.0<\/a> or later (ensure that “Android Edition” is checked in the installer). If you are not familiar with VisualGDB, please first go through the Android Quickstart tutorial<\/a>.<\/p>\n

\u00a0Warning! The Android Emulator does
\nnot support OpenGL. You will need a real device for this
\ntutorial.<\/span><\/p>\n

    \n
  1. Start Visual Studio. Select File->New project->VisualGDB->Android Project Wizard.\"01-newproject\"<\/a><\/li>\n
  2. Select the directory for the project, enter a project name (e.g. GL2Wrapper<\/strong>) and press OK.<\/li>\n
  3. Select “Clone a sample from NDK”:\"02-clone\"<\/a><\/li>\n
  4. Select the hello-gl2<\/strong> project from the list:\"03-gl2\"<\/a><\/li>\n
  5. Select a platform for the newly created project (in this example we select Android 2.3.3):\"04-platform\"<\/a><\/li>\n
  6. When done, press the Finish<\/strong> button. A new Visual Studio project will be created. Select Build->Build Solution to build the project:\"05-project\"<\/a><\/li>\n
  7. Plug in your Android Device. Do not use the Android emulator as it does not support OpenGL.<\/strong> Enable USB debugging and install the USB driver if needed. See this guide <\/a>for more details.<\/li>\n
  8. Put a breakpoint on the line containing the glClearColor()<\/strong> call inside the renderFrame()<\/strong> function.<\/li>\n
  9. Start debugging by selecting Debug -> Start Debugging with GDB in VIsual Studio.<\/li>\n
  10. The app will be automatically deployed and launched and the breakpoint will be hit:\"07-bkpt\"<\/a><\/li>\n
  11. Hover the mouse over the glTriangleVertices<\/strong> definition above renderFrame(). Then click on the “+” symbol. Finally, click on the “0.5” value so that Visual Studio starts editing it.<\/li>\n
  12. Replace “0.5” with “1” and press Enter:\"08-change\"<\/a><\/li>\n
  13. Remove the breakpoint and press F5 to continue running the App.<\/li>\n
  14. Observe that the triangle shape has changed after we have modified glTriangleVertices<\/strong>:\"09-triangles\"<\/a><\/li>\n
  15. When done, press Shift+F5 to stop the debugging session.<\/li>\n<\/ol>\n
