permissions

问题 I am working on an app in which I want to continuously listen to location and battery permissions. Sample scenario: The user opens the app Grants permission access Goes to settings and revokes the permissions Opens the app again The app displays a snackbar that informs the user that permission has been revoked. I am a beginner and I am using the flutter-permissions-handler and the piece of code below shows my usage. _listenForLocationPermission() { Future<PermissionStatus> status =

问题 I'm trying to learn how to get a pretty animate graphic using R and gganimate, and I encounter some issue. When I try to animate my graphics, R seems to edit few PNG files, but then fail to render them. Here is an example of the code I use (tidyverse, gganimate, and gifski were loaded first): p <- ggplot(iris, aes(Sepal.Length, Petal.Length)) + geom_point() p + transition_states(Species) R run the first line without issue. When it comes to the second line, console prints "rendering ----> etc.

问题 I have the following build codes. What I need is for the first loading to ask for the permission only after the page is completely loaded. But what I notice the is that the permission comes out even before the page is loaded and causes very bad view cause its like stuck between the previous page and current page. How to avoid is this ? I have tried even this SchedulerBinding.instance .addPostFrameCallback((_) Widget build(BuildContext context) { WidgetsBinding.instance .addPostFrameCallback((

问题 I have an application that reads SMSs. The app works fine when debugging but when testing it using android instrumented test it throws the following error java.lang.SecurityException: Permission Denial: reading com.android.providers.telephony.SmsProvider This is my test case @RunWith(AndroidJUnit4.class) public class SmsFetcherTest { @Test public void fetchTenSms() throws Exception { // Context of the app under test. Context appContext = InstrumentationRegistry.getContext(); // Fails anyway.

问题 I'm developing an application for our company that eventually will have lots of ways of restricting users to particular sections/modules. While the application is still small, I'd like to move to a new method of storing permissions that, as the application grows, will remain easy to maintain and query. Currently in our MySQL database we have a table called "user" which stores the user's ID, username and password. In a separate table called "user_acl" is the following: user_acl_id acl_root acl

问题 I created a build definition for our nightly build server. After building the project (a windows service), I need to execute a Powershell script to install and start the service. So I added a build step to run the specific Powershell script. Then I installed a TFS Build Agent & Visual Studio at the (soon to be) nightly build server. After running the build script I got an 'exit code 5' which seems to be related to missing administratior permissions. If I start the script as admin on the

问题 I'm using the intent action ACTION_GET_CONTENT . Intent intent = new Intent(Intent.ACTION_GET_CONTENT); intent.setType("image/*"); startActivityForResult(i, 3); I need to use the URI in onActivityResult for copying the image that a user chooses and compress the copied image. But I'm getting this error even after taking uri permission using takePersistableUriPermission(uri, Intent.FLAG_GRANT_READ_URI_PERMISSION) in onActivityResult. This works well when I use the Intent action ACTION_OPEN

问题 I created an index.js, index.html and package.json file and I wanted to add express. When I write 'npm install express' in the terminal, I'm getting the error below. So far, I tried 'sudo npm install -g express', deleting node and npm completely and re-install. I also went through other questions over here but none of them worked out for me. Whatever I write with npm I get the same error. (I'm using macOS) Do you have any suggestions? This is the error I am getting: Error: EROFS: read-only
