android - Android如何在OREO的第一个运行时运行权限

问题描述

我希望用户在第一次打开应用程序时应该询问而不是第二次。这个错误是在 oreo 版本上

if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            // only for gingerbread and newer versions

            Dexter.withActivity(getActivity())
                    .withPermissions(
                            Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE,
                            Manifest.permission.CAMERA, Manifest.permission.CALL_PHONE
                    )
                    .withListener(new MultiplePermissionsListener() {
                        @Override
                        public void onPermissionsChecked(MultiplePermissionsReport report) {
                            // check if all permissions are granted
                            if (report.areAllPermissionsGranted()) {
                                // do you work now

                            }

                            // check for permanent denial of any permission
                            if (report.isAnyPermissionPermanentlyDenied()) {
                                // permission is denied permenantly, navigate user to app settings
                            }
                        }

                        @Override
                        public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                            token.continuePermissionRequest();
                        }
                    })
                    .onSameThread()
                    .check();
        }

解决方案

我正在使用从 6.0 到 9.0 的这段代码，它可以工作。内部onCreate()方法。添加这个。

笔记 PERMISSION_REQUEST_CODE == 1

这只是运行时权限的示例代码。你可以改变它

    if (ContextCompat.checkSelfPermission(Login.this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(Login.this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, PERMISSION_REQUEST_CODE);
    }

    if (ContextCompat.checkSelfPermission(Login.this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(Login.this, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_CODE);
    }
    if (ContextCompat.checkSelfPermission(Login.this, Manifest.permission.READ_PHONE_STATE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(Login.this, new String[]{Manifest.permission.READ_PHONE_STATE}, PERMISSION_REQUEST_CODE);
    }
