FileNotFoundException 打开失败：ENOENT（没有这样的文件或目录），同时通过三星设备上传任何类型的文件

Question

我想通过从文件管理器中选择文件来将文件上传到服务器所以我使用此代码单击按钮打开了文件管理器，

 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);
            }
        }
    });

和 onActivityResult 方法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("");
                }
            }
        }

它在其他设备上运行良好，但在三星设备上我有

 java.io.FileNotFoundException: /document/primary:Xender/other/When Strangers Meet_ 3 in 1 Box - John Harker.pdf: open failed: ENOENT (No such file or directory)

我的上传代码是

Answer 1

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

查看 contentUri.getPath() 的值，发现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);
