谷歌游戏机不接受Android11抢占存储manage_external_storage权限

Question

我的应用程序在10版以下运行良好，但Android11及更高版本不支持外部存储。我的选取器没有选取任何文档文件。但在清单中授予manageexternalstorage权限后，googleplaystore没有批准我的应用程序。如果您知道所有文件访问权限的替代解决方案，请提供帮助。

Answer 1

像下面这样尝试。根据需要创建全局变量或根据需要重构。这是在Android 11上测试的。

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />



private void OpenCamera() {

        try {
            Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            File photoFile = null;
            try {
                photoFile = createFile();
            } catch (Exception ex) {
                // Error occurred while creating the File
            }
            // Continue only if the File was successfully created
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(getActivity().getApplicationContext(), getActivity().getApplicationContext().getPackageName() + ".fileprovider", photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, 3);
            }
            //   }
        } catch (Exception e) {
        }

    }

 private File createFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_" + timeStamp + "_";
        File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(imageFileName,  /* prefix */".jpg",         /* suffix */storageDir      /* directory */);

        // Save a file: path for use with ACTION_VIEW intents
        ImageLoc = image.getAbsolutePath();

        return image;


    }



// Open Gallery
    private void OpenGallery() {

        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Image"), 1);
    }




// onActivityResult handles gallery pics, camera pics and pdf.
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1) {
            if (resultCode == Activity.RESULT_OK) {

                if (data.getData() != null) {

                    try {
                        Uri imageUri = data.getData();
                        File file = new File(Path_from_Uri.getPath(getActivity(), imageUri));

                    } catch (Exception e) {
                        Toast.makeText(getActivity(), "Please Select Image from Gallery", Toast.LENGTH_LONG).show();
                    }

                }

            }
        } else if (requestCode == 3) {

            try {
                File file = new File(ImageLoc);
              
            } catch (Exception e) {
                Log.d("TAG", e.toString());
            }
        }


    }
