推荐答案

仿真器工作正常。你用什么一块code存储位图PNG？

The emulator works fine. What piece of code did you use to store the bitmap as png?

细下工作在模拟器中：

Bitmap bitmap = createYourBitmap();
OutputStream stream = new FileOutputStream("/sdcard/test.png");
/* Write bitmap to file using JPEG or PNG and 80% quality hint for JPEG. */
bitmap.compress(CompressFormat.PNG, 80, stream);
stream.close();
