在没有Android的情况下从Java使用android.graphics.Bitmap

Question

I need to use android.graphics.Bitmap in my Java project without Android platform. The problem is that I want to process the picture which comes to the server from Android device as a Bitmap. So, I need some methods that use native code. How can I get these native methods? I tried to find them at http://androidxref.com but if I have, for example,

static int Bitmap_width(JNIEnv* env, jobject, SkBitmap* bitmap) {return bitmap->width();}

clicking width() refers to the new search where there are lots of classes contating different width() .

Answer 1

You shouldn't do that. The android libraries are not meant to be used for non android applications. Especially the native code.

As long as you send a bitmap image, any non-android library will be able to read it.

You can event send the image raw pixels. It's like sending a list of bytes. Any language will be able to read incomming bytes.

Answer 2

I managed to do this. Now the server gets only width, height of the image and array of pixels derived by bitmap.getPixels(...) on the device and builds the picture as described here
