 Android
 =======
 
 Prerequisites
 -------------
 
 _Currently we only support building Skia for Android on a Linux or Mac host! In addition,
  we only use the Mac build for local development. All shipping variants are compiled on
  Linux for performance reasons._

 The -d option enables the build system to target the build to a specific
 architecture such as MIPS (generic), x86 (generic) and ARM (generic and device
 specific flavors for Nexus devices). This in turn allows Skia to take
 advantage of specific device optimizations (e.g. NEON instructions).
 
 Generate build file from GYP
 ----------------------------
 
-We use the open-source gyp tool to generate build files from our multiplatform
-"gyp" files. While most other platforms enable you to regenerate these files
-using `./gyp_skia` it is recommend that you do NOT do this for Android.  Instead
-you can rely on it being run automatically by android_ninja.

 Faster rebuilds
 ---------------
 
 You can use ccache to improve the speed of rebuilding:
 
-  # You may want to add this export to your shell's .bash_profile or .profile
-  export ANDROID_MAKE_CCACHE=[ccache]
+    # You may want to add this export to your shell's .bash_profile or .profile
+    export ANDROID_MAKE_CCACHE=[ccache]
 
 Build and run executables on the device
 ---------------------------------------
 
 The build system packages the Skia executables as shared libraries.  As such,
 in order to run any executable on the device you must install the library and
 a launcher executable on your device.  To assist in this process there is a
 script called `android_run_skia` that is located in the
 `platform_tools/android/bin` directory.
