补充

1. ndk开发: native方法方法名以”native”开头,并遵循小驼峰命名法.
   例如,以下示例来自Bitmap.java:

   private static native Bitmap nativeCreateFromParcel(Parcel p);

   在Canvas.java同时存在两种方式,比较混乱:

   private native void native_drawBitmap(long nativeCanvas,
   Bitmap bitmap,
           float srcLeft, float srcTop, float srcRight, float srcBottom,
           float dstLeft, float dstTop, float dstRight, float dstBottom,
           long nativePaintOrZero, int screenDensity, int bitmapDensity);
   private static native void native_drawBitmap(long nativeCanvas, int[] colors,
                                               int offset, int stride, float x,
                                                float y, int width, int height,
                                                boolean hasAlpha,
                                                long nativePaintOrZero);

2. native方法全部使用private修饰符,通过使用java方法调用.
