1. NDK development: The method name of the native method starts with "native", and follows the small camel case nomenclature, and does not contain '_' in the name.

   For example, the following example is from Bitmap.java:

   private static native Bitmap nativeCreateFromParcel(Parcel p);

   CanvasThere are two ways at the same time, which are confusing :

   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. nativeThe methods all use privatemodifiers by using java method calls.
