JAVAlang.RuntimeException:无法传递结果ResultInfo需要安卓。准许读取外部存储器或grantUriPermissio

Question

我正在跟随一个教程，在这个link上从安卓上传视频到服务器。但当我执行这个活动时，它给了我运行时异常。根据例外情况，我在manifest文件中添加了权限。但还是会出错。这是我的活动文件

public class UploadActivity extends AppCompatActivity implements View.OnClickListener {
    private Button buttonChoose;
    private Button buttonUpload;
    private TextView textView;
    private TextView textViewResponse;
    private static final int SELECT_VIDEO = 3;
    private String selectedPath;
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upload);
        report = getIntent().getStringExtra("report");
        buttonChoose = (Button) findViewById(R.id.buttonChoose);
        buttonUpload = (Button) findViewById(R.id.buttonUpload);
        textView = (TextView) findViewById(R.id.textView);
        textViewResponse = (TextView) findViewById(R.id.textViewResponse);
        buttonChoose.setOnClickListener(this);
        buttonUpload.setOnClickListener(this);
    }
    private void chooseVideo() {
        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select a Video "), SELECT_VIDEO);
    }
    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            if (requestCode == SELECT_VIDEO) {

                Uri selectedImageUri = data.getData();
                selectedPath = getPath(selectedImageUri);
                textView.setText(selectedPath);
            }
        }
    }
    public String getPath(Uri uri) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();
        cursor = getContentResolver().query(
                安卓.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        String path = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DATA));
        cursor.close();
        return path;
    }

    private void uploadVideo() {
        class UploadVideo extends AsyncTask<Void, Void, String> {
            ProgressDialog uploading;
            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                uploading = ProgressDialog.show(UploadActivity.this, "Uploading File", "Please wait...", false, false);
            }
            @Override
            protected void onPostExecute(String s) {
                super.onPostExecute(s);
                uploading.dismiss();
                textViewResponse.setText(Html.fromHtml("<b>Uploaded at <a href='" + s + "'>" + s + "</a></b>"));
                textViewResponse.setMovementMethod(LinkMovementMethod.getInstance());
            }

            @Override
            protected String doInBackground(Void... params) {
                UploadFile u = new UploadFile();
                String msg = u.uploadVideo(selectedPath);
                return msg;
            }
        }
        UploadVideo uv = new UploadVideo();
        uv.execute();
    }

    @Override
    public void onClick(View v) {
        if (v == buttonChoose) {
            chooseVideo();
        }
        if (v == buttonUpload) {
            uploadVideo();
        }
    }
}

我正在棉花糖上测试它
多谢各位

Answer 1

试试这个

    private static final int REQUEST_STORAGE = 112;

    @Override
        public void onClick(View v) {
        if (v == buttonChoose) {
            if (Build.VERSION.SDK_INT >= 23) {
                String[] PERMISSIONS = {android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE};
                if (!hasPermissions(mContext, PERMISSIONS)) {
                    ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_STORAGE );
                } else {
                      chooseVideo();
                }
            } else {
                chooseVideo();
            }
        }
        if (v == buttonUpload) {
            uploadVideo();
        }
    }

获取权限结果

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case REQUEST_STORAGE: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                   chooseVideo();
                } else {
                    Toast.makeText(mContext, "The app was not allowed to write to your storage.", Toast.LENGTH_LONG).show();
                }
            }
        }
    }

检查棉花糖的权限

    private static boolean hasPermissions(Context context, String... permissions) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
            for (String permission : permissions) {
                if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                    return false;
                }
            }
        }
        return true;
    }

显示

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