MediaPicker | 多媒体选择器，仿WeChat风格，目标：集拍照，相册，视频，录像，文件选择一体

I'm using Xam.Plugin.Media to capture a photo from the camera and I want to use the stream from the image to print it on a pdf. I tried so many ways to do this but no one is working and always is printed a gray rectangle with the "Image could not be read" on the center. Anyone have an ideia how to fix this ?

here is my code

im developing a Xamarin Forms App where the User can take Videos and save them to the public external storage. Im currently saving the filename of the created video. My way of saving the video:

Is it possible to take a photo using Xamarin Essentials with Android 11 - Api 30 and save it to the device? I have used Xam.Media.Plugin in the past to do this. But I would prefer to only use Xamarin Essentials. I currently have my App taking photos and then programmatically uploading each photo to Azure (which is working well). However, I also want to save a copy of the photo to the device as a backup when internet connectivity is poor, as is regularly the case for my users. The below code doesn't catch and display both alerts below, however nothing is saved to my device. My code is included below:

Hi Xamarin GODS and GODDESSES. I am trying to find the solution to bind images selected with Media Picker (capture photo) and Media Gallery (pick photos), in order to save them on the local SQLite database and display them on the List View later on. I have two buttons event handlers for taking photos from a camera and picking photos from a gallery. They are both similar methods (Also, is there a better method for those two methods to avoid stream?). However, I am unsure how to bind their results and display them in my List View and SQLite database. There is a save button on the page that saves all inputs made by users such as Title, experience, location, and images (which I am struggling with, how to save images?). When the save button is clicked, changes are presented in List view and SQLite. It is quite easy to do that for text entry. However, how to do it for images???? I assume it should be somehow converted into bytes and arrays. But how? Please help!!!! Below is my code with mentioned methods and how I am displaying it to the List View. So basically, what I want to do is, have user's input in terms of EXPERIENCE, TITLE, LOCATION and IMAGE. Have it in my model Post class, save it to the SQ and display it in the list view.

For an android phone.

In .net MAUI, I want to customize a window with a "Take Photo" button, once this button is clicked I want to take a photo.

I know in Xamarin, I can install package Xam.Plugin.Media and then call Plugin.Media.CrossMedia.Current.TakePhotoAsync method to take a photo but I don't know how to do it in MAUI. I don't know if I need to install any packages for MAUI.

I know in MAUI, I can use Microsoft.Maui.Essentials and call MediaPicker.CapturePhotoAsync() to take a photo, but this method calls the default Camera app of the mobile device.

Getting application info from package manager leads to app crash, why this has occurred and how to fix it?

I am developing a barcode reader with Xamarin.Forms. And I'm trying to scan the image on Android device.

First I select the image from the gallery with Xamarin.Essentials MediaPicker and from the path of this image I get an RGBLuminance with the Dependency class.

Then I am trying to decode this RGBLuminance with the Decode() method of the ZXing BarcodeReaderGeneric class. However, the result always returns null.
