Question

我在保存后找到照片时遇到问题。这是我如何创建Intent从相机拍摄照片并将filePath保存到它。

private void takePhoto(int position)
{
    Meter meter = adapter.getItem(position);
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File storageDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
    File tempFile = createTempFile(meter.id, JPEG_FILE_SUFFIX, storageDir);
    if(tempFile != null)
    {
        lastPhotoPath = tempFile.getAbsolutePath();
        Log.d(TAG, "temp picture path=" + lastPhotoPath);
        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
            Uri.fromFile(tempFile));
        try
        {
            startActivityForResult(takePictureIntent, TAKE_PHOTO_REQUEST);
            lastPhotoPosition = position;
        }
        catch(ActivityNotFoundException exc)
        {
            Log.e(TAG, "activity to take photo not found");
        }
    }
}

然后我想将此图像上传到服务器。我是这样做的。

public void compose(OutputStream out) throws DataStorageException
{
    Log.d("MainMenuActivity", "file not found in path " + path);
    InputStream in = null;
    try
    {
        in = new BufferedInputStream(new FileInputStream(path));

        // TODO: there is a better way
        byte[] buf = new byte[8192];
        while(true)
        {
            int length = in.read(buf);
            if(length < 0)
                break;
            out.write(buf, 0, length);
        }
    }
    catch(FileNotFoundException exc)
    {
        throw new DataStorageInternalErrorException("FileNotFoundException, FileRequestComposer compose");
    }
    catch(IOException exc)
    {
        // TODO: probably network error
        throw new DataStorageInternalErrorException("IOException, FileRequestComposer compose");
    }
    finally
    {
        if(in != null)
        {
            try
            {
                in.close();
            }
            catch(IOException exc)
            {
                // FIXME
            }
        }
    }
}

我从save和filePath检查filePath以保存它们完全相同：

temp picture path=/mnt/sdcard/Pictures/19520983731349.jpg

file not found in path /mnt/sdcard/Pictures/19520983731349.jpg

方法compose()

中抛出了异常

FileNotFoundException, FileRequestComposer compose

我做错了什么想法？

P.S。我无法在/ mnt / sdcard / Pictures mb中看到此文件。他迷路了还是像这样？请提出任何想法。

Answer 1

问题可能在于您创建文件的方式。而不是createTempFile尝试常规构造函数：

File tempFile = new File(storageDir,  meter.id + JPEG_FILE_SUFFIX);

通常，您还需要确保您的storageDir文件夹存在，并根据需要使用mkdirs创建。

Answer 2

添加此路径以在sdcard上存储图像。

final String uploadFilePath = "/mnt/sdcard/";

上传Photo时出现Android FileNotFoundException
