Set up ADB environment in Mac OSX

  • Open Terminal
  • Type cd ~ this will take you to your home directory
  • Type touch .profile this will create a hidden file named profile
  • Type open -e .profile this will open the file you just created in TextEdit
  • In the file, type exportPATH=${PATH}:/pathToTheAndroidSdkFolder/android-sdk-mac_86/platform-tools
  • Save file, close TextEdit, Quit Terminal, and Relaunch Terminal
  • NOTE: By creating an environment variable you won't need to cd to the Android/tools folder every time you want to run ADB

Play video inside OpenGL ES by using MediaCodec

In Android 4.1 (API 16) and above, MediaCodec is introduced by Android. By using MediaCodec, we can easily decode video without using Android NDK, like creating video playback application, etc. In game development, video is also needed to make the game environment more realistics, like when you are playing a racing game with video banner around the track. In here, I'll introduce of how to decode the video and render it into OpenGL ES. Firstly, we prepare some stuffs to decode the video, like MediaExtractor and MediaCodec. private boolean initExtractor() { extractor = new MediaExtractor(); try { extractor.setDataSource(mFilePath); } catch (IOException e) { return false; } // get video track for (int i = 0; i < extractor.getTrackCount(); i++) { MediaFormat format = extractor.getTrackFormat(i); String mime = format.getString(MediaFormat.KEY_MIME); if (mime.startsWith("video/")) { ...

Android, OpenCL, GPU

GPU, Graphics Processing Unit , is the master of the graphics performance on our Android device.It plays an important role when playing games, playing high quality video (HD), and even showing smooth UI. Therefore, it needs to support many rendering libraries, like OpenGL ES, OpenCV, OpenVG, etc. It seems that GPU on our Android device is performing the same role as our VGA on PC. But, Android is just growing faster recently, so do all GPUs device support all those libraries? After investigating by reading lots of articles, etc, I figured out that GPU on our Android device are still limited. Few GPUs supports OpenCL library. And what does OpenCL really do? OpenCL, Open Computing Language , is recently used for non-graphical computing, like image processing, vector computation, matric computation, etc. See sample from Nvidia for more details by clicking here . Here are Android GPUs that support OpenCL. Qualcomm (Adreno 300 series) References: https://developer.qualcomm.com/...

Check OpenGL ES capability on Android

There are lots of Android devices around the world. And when you want to create one application that need OpenGL ES, you would think (what I thought) if the user's device can run smoothly by checking the OpenGL ES version because this is important. So how to check the OpenGL ES version? By using SystemService. This is the simplest one. You don't need to create any OpenGL ES component. final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE); final ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo(); final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x30000; By using glGetService . By doing this, you can get more information, like the vendor, chip, shading version, etc. But, you need to have GL context first. String glVersion = GLES20.glGetString(GLES20.GL_VERSION); String glRenderer = GLES20.glGetString(GLES20.GL_RENDERER); String glVendor = GLES20.glGetString(GLES20.GL_VENDOR); String g...
