当我将位图图像插入文件目录时,它显示文件未找到异常,它显示的是一个目录.

这是我的代码:

            File mFolder = new File(getFilesDir() + "/sample");

            if (!mFolder.exists()) {
                mFolder.mkdir();
            }
             FileOutputStream fos = null;
             try {
                 fos = new FileOutputStream(mFolder);
                 bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);

                 fos.flush();
                 fos.close();
              //   MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
             }catch (FileNotFoundException e) {

                 e.printStackTrace();
             } catch (Exception e) {

                 e.printStackTrace();
             }

logcat的:
