我的应用程序有能力选择照片从库。正是我想从这个选择文件的路径。

My app has ability to select photo from library. Exactly I want file path from this selection.

这是在code创建的意图来选择照片：

This is the code to create intent for selecting photo:

    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK,
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, INTENT_REQUEST_CODE_SELECT_PHOTO);

这是在code，它会从URI文件路径：

This is the code that gets file path from URI:

    Cursor cursor = null;
    String path = null;
    try {
        String[] projection = { MediaStore.Images.Media.DATA };
        cursor = context.getContentResolver().query(contentUri, projection, null, null, null);
        int columnIndex = cursor.getColumnIndexOrThrow(projection[0]);
        cursor.moveToFirst();
        path = cursor.getString(columnIndex);
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
    return path;

在谷歌照片应用程序的一切昨日的更新完全正常工作。 解析URI后现在路径为空。

Before yesterday's update of Google Photos app everything worked perfectly fine. Now path is null after parsing URI.

URI是与此类似： content://com.google.android.apps.photos.contentprovider/0/1/content%3A%2F%2Fmedia%2Fexternal%2Fimages%2Fmedia%2F75209/ACTUAL

URI is similar to this: content://com.google.android.apps.photos.contentprovider/0/1/content%3A%2F%2Fmedia%2Fexternal%2Fimages%2Fmedia%2F75209/ACTUAL

我也试图创造意图与Intent.ACTION_GET_CONTENT行动 - 没有运气

I also tried to create intent with Intent.ACTION_GET_CONTENT action - no luck.

推荐答案

下面code为我工作，以获取内容的URI在谷歌最新的照片，以及。 我曾尝试是写入临时文件，并返回临时图像URI，如果它有权力的内容URI。

Below code is working for me to get content URI on latest Google Photos as well. What i have tried is writing to temp file and return temp image URI, if it has authority in content URI.

您可以尝试相同的：

public static String getImageUrlWithAuthority(Context context, Uri uri) {
    InputStream is = null;
    if (uri.getAuthority() != null) {
        try {
            is = context.getContentResolver().openInputStream(uri);
            Bitmap bmp = BitmapFactory.decodeStream(is);
            return writeToTempImageAndGetPathUri(context, bmp).toString();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }finally {
            try {
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
    return null;
}

public static Uri writeToTempImageAndGetPathUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}
