打开文件选择器的代码

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
activity.startActivityForResult(Intent.createChooser(intent, "Open CSV"), READ_REQUEST_CODE);

重现问题的步骤

1）打开画廊供挑选照片

2）从幻灯片菜单中选择ES File Explore

3）现在一些文件URI正常工作，一些文件崩溃了

注意：-FileProvider已经实施

问题似乎出在Nougat（7.1.1）nexus（已测试！）

解决方法

  

从您的代码调用 getFilePathFromUri（this，uri）

public static String getFilePathFromUri(Context context, Uri _uri) {
    String filePath = "";
    if (_uri != null && "content".equals(_uri.getScheme())) {
        //Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
        //context.revokeUriPermission(_uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
        Cursor cursor = null;
        try {
            cursor = context.getContentResolver().query(_uri,
                    new String[]
                            {
                                    MediaStore.Images.ImageColumns.DATA,
                                    MediaStore.Images.Media.DATA,
                                    MediaStore.Images.Media.MIME_TYPE,
                                    MediaStore.Video.VideoColumns.DATA,
                            }, null, null, null);
            cursor.moveToFirst();
            filePath = cursor.getString(0);
        } catch (SecurityException e) {
            //if file open with third party application
            if (_uri.toString().contains("/storage/emulated/0")) {
                filePath = "/storage/emulated/0" + _uri.toString().split("/storage/emulated/0")[1];
            }
        } finally {
            if (cursor != null)
                cursor.close();
        }

    } else {
        filePath = _uri.getPath();
    }
    return filePath;
}
