Java FileNotFoundException打开失败：在三星设备上载任何类型的文件时Enoint（没有此类文件或目录）

我想通过从文件管理器中选择文件将文件上载到服务器，因此我已使用此代码单击按钮打开文件管理器

 button_upload_attachment.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String[] galleryPermissions = {android.Manifest.permission.READ_EXTERNAL_STORAGE, android.Manifest.permission.WRITE_EXTERNAL_STORAGE};

            if (EasyPermissions.hasPermissions(CIBILCaptureandUPLOAD.this, galleryPermissions)) {

                Intent intent = new Intent();
                intent.setType("*/*");
                intent.setAction(Intent.ACTION_GET_CONTENT);
                startActivityForResult(intent, 1);
        } else {
                EasyPermissions.requestPermissions(this, "Access for storage",
                        101, galleryPermissions);
            }
        }
    });

在activityresult方法中，我做了类似的事情来获取文件的路径，并使UploadToserver函数用于上传

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    //ImagesData = data;
    try {
        // When an Image is picked
        if (requestCode == RESULT_LOAD_IMG && resultCode == RESULT_OK
                && null != data) {

            Uri contentUri=data.getData();
            Log.e("bbbbbbbbbbbbbb", contentUri.toString());

            if(contentUri.toString().endsWith(".png")||contentUri.toString().endsWith("jpg") ||
                    contentUri.toString().endsWith(".pdf")){

                photoFile= new File(contentUri.getPath());

                if (photoFile.exists()) {

                    Log.e("photoFile", "File Exists");
                }
                if (photoFile != null) {
                    new AsyncTask<String, String, File>() {
                        ProgressDialog pd;

                        @Override
                        protected void onPreExecute() {
                            pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Compressing...");
                            Log.e("PreExecute", "Compressing");
                        }

                        @Override
                        protected File doInBackground(String[] params) {
                            return photoFile;
                        }

                        @Override
                        protected void onPostExecute(File result) {
                            pd.dismiss();
                            if (result != null) {
                                new CIBILCaptureandUPLOAD.UploadFileToServer().execute(result);
                            }
                        }
                    }.execute("");
                }

            }else {
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                Cursor cursor = getContentResolver().query(contentUri,
                        filePathColumn, null, null, null);
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String filePath = "";
                if (cursor.moveToFirst()) {
                    filePath = cursor.getString(columnIndex);
                }
                Log.e("PATH", filePath);

                photoFile = new File(filePath);

                if (photoFile.exists()) {

                    Log.e("photoFile", "File Exists");
                }
                if (photoFile != null) {
                    new AsyncTask<String, String, File>() {
                        ProgressDialog pd;

                        @Override
                        protected void onPreExecute() {
                            pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Compressing...");
                            Log.e("PreExecute", "Compressing");
                        }

                        @Override
                        protected File doInBackground(String[] params) {
                            return photoFile;
                        }

                        @Override
                        protected void onPostExecute(File result) {
                            pd.dismiss();
                            if (result != null) {
                                new CIBILCaptureandUPLOAD.UploadFileToServer().execute(result);
                            }
                        }
                    }.execute("");
                }
            }
        }

我的上传代码是

私有类UploadFileToServer扩展异步任务{ 私有静态最终字符串TAG=“UploadFileToServer”

查看

contentUri.getPath（）

的值，确定它不是有效的文件系统路径

相反，您应该为获得的uri打开一个InputStream，并从流中读取文件内容

InputStream is = getContentResolver().openInputStream(contentUri);

---

你有一个if-else语句，但没有告诉问题是在if还是else块中。你应该只发布该块，而不让我们猜测。我可以在哪里做这件事？然后如何使用InputStream的这个“is”对象你应该使用它来上传你的图像。但是你没有发布图像上传代码…

entity.addPart（“图像”），new FileBody（sourceFile））；

。看起来你好像运气不好。这将是你必须更改的唯一语句。但恐怕它无法接受输入流。

    // private ProgressBar progressBar;
    // private String filePath = null;
    // private TextView txtPercentage;

    private ProgressDialog pd;
    long totalSize = 0;

    @Override
    protected void onPreExecute() {
        // setting progress bar to zero
        // progressBar.setProgress(0);
        pd = ProgressDialog.show(CIBILCaptureandUPLOAD.this, "", "Loading...");
        super.onPreExecute();
    }

    @Override
    protected void onProgressUpdate(Integer... progress) {
        // Making progress bar visible
        // progressBar.setVisibility(View.VISIBLE);
        // updating progress bar value
        pd.setMessage("Loading..." + progress[0]);
        // progressBar.setProgress(progress[0]);
        // updating percentage value
        // txtPercentage.setText(String.valueOf(progress[0]) + "%");
