Empower your users to upload photos and videos to your iOS or Android application with the Media Picker in .NET MAUI.

Nowadays, it’s common to allow users to upload photos or videos to your apps. For example, banking applications let users upload essential documents for processing, saving them the time of going to a physical office. Providing this kind of experience to your apps adds a lot of value to the user experience. In this article, we’ll show you how to implement Media Picker with .NET MAUI in a straightforward way.


First, you’ll need to add some platform settings.

Android settings On Android

To make sure that your app runs smoothly on different versions of Android, you need to implement some general permissions as well as version-specific ones.

You have two ways to do that:

1. Assembly-Based Permissions

Go to Platform > Android > AndroidApplication.cs and set the following permissions:

  • You need CAMERA as general permission.
[assembly: UsesPermission(Android.Manifest.Permission.Camera)]
  • If your app targets Android 12 or lower, add the READ_EXTERNAL_STORAGE and WRITE_EXTERNAL_STORAGE permissions.
[assembly: UsesPermission(Android.Manifest.Permission.ReadExternalStorage, MaxSdkVersion = 32)]

[assembly: UsesPermission(Android.Manifest.Permission.WriteExternalStorage, MaxSdkVersion = 32)]
  • If your app targets Android 13 or higher, add the READ_MEDIA_IMAGES, READ_MEDIA_VIDEO and READ_MEDIA_AUDIO permissions.
[assembly: UsesPermission(Android.Manifest.Permission.ReadMediaAudio)]

[assembly: UsesPermission(Android.Manifest.Permission.ReadMediaImages)]

[assembly: UsesPermission(Android.Manifest.Permission.ReadMediaVideo)]
  • Additionally, you can include the following properties to filter out devices without cameras. If necessary, set them to False to make them optional.
[assembly: UsesFeature("", Required = true)]

[assembly: UsesFeature("", Required = true)]

2. Updating the Android Manifest

Go to Platform > Android > Android Manifest.cs and set the following permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="32" />
<!-- Required only if your app needs to access images or photos that other apps created -->
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
<!-- Required only if your app needs to access videos that other apps created -->
<uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
<!-- Required only if your app needs to access audio files that other apps created -->
<uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />

⚠ Note that these permissions comply with the same conditions explained in the first form, depending on the Android version.

  • If your project targets Android 11 (R API 30) or higher, add the following query/intent nodes in the manifest node to update the manifest queries that use the Android package visibility requirements:
    <action android:name="" />

iOS settings On iOS

On iOS/Mac Catalyst, go to Platform > iOS or MacCatalyst > Info.plist and set the following permissions:

<string>This app needs access to the camera to take photos.</string>

<string>This app needs access to microphone for taking videos.</string>

<string>This app needs access to the photo gallery for picking photos and videos.</string>

<string>This app needs access to photos gallery for picking photos and videos.</string>

✍️ To request permissions, it’s vital to consider the description attached to each one. These descriptions will be presented to the user during the request process.

🚧 For Windows, you don’t need any additional configuration.

How Does Media Picker Work?

Media Picker’s capabilities are made possible by the IMediaPicker interface, which enables users to capture or select photos and videos on their devices. The Microsoft.Maui.Media namespace contains the default implementation of the IMediaPicker interface, which you can access through the MediaPicker.Default property.

IMediaPicker includes a set of methods that return a FileResult. These include the following:

📷 For photos

  • PickPhotoAsync: Allows users to open the media browser and select a photo from the available options.
  • CapturePhotoAsync: Responsible for opening the camera to take a photo.

🎥 For videos

  • PickVideoAsync: Allows users to open the media browser to select a video.
  • CaptureVideoAsync: Responsible for opening the camera to take a video.

⚠ To ensure that permission checks and requests are handled automatically by .NET MAUI, all methods should be called on the UI thread.

📝 Optionally, all of the aforementioned methods receive a MediaPickerOptions parameter that allows you to add a title to the dialog to be displayed. Note that this only works on some operating systems.

Now Let’s Code

It’s time to translate everything you’ve learned so far into code. The following graphic demonstrates the structure you’ll use to organize each detail in the code.

Demonstrating the MediaPickerOptions

⭐ Now let’s implement the code, which allows you to open the Media Picker. This example uses the PickPhotoAsync() method.

Working with XAML

Let’s create a button and add an image control to display the selected photo.

Adding a button

<VerticalStackLayout Spacing="25" Padding="30,0" VerticalOptions="Center">
  <Image x:Name="myImage" 
  HorizontalOptions="Center" />
  Text="Pick a picture"
  HorizontalOptions="Center" />

Creating the Method

Let’s create an asynchronous method called TakePhoto for this example. The following code allows the user to tap a button and select a photo from a dialog. You’ll achieve this with the PickPhotoAsync method.

✍️ Note that all of this will be saved in the Photo variable, which is a FileResult. Later, you’ll use this variable to obtain information about the selected image (which you can see in the next step).

private async void TakePhoto(object sender, EventArgs e)
  FileResult photo = await MediaPicker.Default.PickPhotoAsync(new MediaPickerOptions
    Title = "Select your photo"
  // Here, add the code that is being explained in the next step.

Please keep in mind that adding the title with MediaPickerOptions is not mandatory.

Showing the Image

As mentioned previously, the photo variable provides access to information such as the file name or full path among other details. This example uses the OpenReadAsync method to retrieve the image.

In the previous blog section’s code, where it says // Here, add the code that is being explained in the next step, insert the following code:

if (photo != null)
  var stream = await photo.OpenReadAsync();
  myImage.Source = ImageSource.FromStream(() => stream);

And that’s all! 😍 Let’s see the result!

Gif of the final MediaPicker

Want to take a new photo instead of selecting an existing one? Add the code presented below. This example uses the CapturePhotoAsync method to capture the photo.

private async void TakePhoto(object sender, EventArgs e)
FileResult photo = await MediaPicker.Default.CapturePhotoAsync();
  if (photo != null)
    // Getting the file result information
    using Stream sourceStream = await photo.OpenReadAsync();
    // Saving the file in your local storage
    string localFilePath = Path.Combine(FileSystem.CacheDirectory, photo.FileName);
  await sourceStream.CopyToAsync(File.OpenWrite(localFilePath));


I hope this article about using Media Picker to enable your users to upload photos and videos to your app was beneficial to you! I encourage you to implement these tips into your next project. 💚💕
