我正在尝试将位图保存到Pictures目录中.这是代码

            File path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);

            File file = new File(path,"test1.PNG");
            try { 
                   path.mkdirs();
                   OutputStream out = new FileOutputStream(file);
                   mBitmap.compress(Bitmap.CompressFormat.PNG,90,out);
                   out.flush();
                   out.close();

            } catch (Exception e) {
                   e.printStackTrace();
                   Log.w("ExternalStorage","Error writing " + file,e);
            }

但是执行卡在OutputStream out = new FileOutputStream(file);
我用调试器和完整路径返回mnt / sdcard / Pictures / test1.PNG,是mnt /罪魁祸首为什么我无法通过OutputStream out = new FileOutputStream(file);？因为我只能在我的文件目录中看到sdcard /.

谢谢！
