我正在尝试将手机上的图片上传到我在服务器上创建的数据库。

那是我得到的错误信息。
这是我用来检查 getAbsolutePath(); 的代码。
if (requestCode == READ_REQUEST_CODE && resultCode == RESULT_OK) {
// The document selected by the user won't be returned in the intent.
// Instead, a URI to that document will be contained in the return intent
// provided to this method as a parameter.
// Pull that URI using resultData.getData().
//Uri uri = null;
if (data != null) {
//super.onActivityResult(requestCode, resultCode, data);
Uri selectedImageURI = data.getData();
File myFile = new File(selectedImageURI.getPath());
//File myFile = new File(data.getData().toString());
//File imageFile = new File(getRealPathFromURI(selectedImageURI));
//new UploadFileAsync().execute(myFile.getAbsolutePath().toString());
new UploadFileAsync().execute(myFile.getAbsolutePath().toString());
//Log.i(TAG, "Uri: " + selectedImageURI.toString());
//showImage(uri);
}
}
