Android-保留Bitmap到SDCard

public void saveMyBitmap(String bitName, Bitmap mBitmap) throws IOException {        File f = new File("/sdcard/" + bitName + ".png");        f.createNewFile();        FileOutputStream fOut = null;        try {                fOut = new FileOutputStream(f);        } catch (FileNotFoundException e) {                e.printStackTrace();        }        mBitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);        try {                fOut.flush();        } catch (IOException e) {                e.printStackTrace();        }        try {                fOut.close();        } catch (IOException e) {                e.printStackTrace();        }}
