Preview images or videos with Camera Preview on Android

Many applications such as social media, retail, and banking apps use the built-in device camera to preview the camera content and do further processing. The Camera Preview feature of App Live enables you to preview the camera content in your app and test the related scenarios.

With Camera Preview, you can inject an asset (image or video) into your app and view the injected asset in the camera preview. You can use Camera Preview to test scenarios such as:

• Manually capturing an image by clicking the camera shutter button.
• Automatically capturing an image by detecting the face liveliness.

Supported devices and APIs

• Supported devices: Devices running Android OS 9 and higher.
• Supported APIs: Apps using the Camera X API.

Prerequisite

The Camera Preview feature only works with image and video injection. Ensure that you enable either Image Injection or Video Injection, or both. If both image and video injection settings are disabled, Camera Preview is automatically disabled.

Enable the Camera Preview setting for your app

To enable the Camera Preview setting:

1. Log in to the App Live dashboard.
2. Upload your app from the Select Source panel.
3. After your app is uploaded, click the configuration icon next to the file name of your app.
4. Under App Configurations, enable Camera Preview.
   

After the Camera Preview setting is enabled, select your device from the list of available devices in the device listing to launch your test session.

Upload an asset and test your app by injecting the asset

To upload an asset and inject into your app:

1. Log in to the App Live dashboard.
2. Select your app and a device to launch a test session.
3. On the App Live vertical toolbar, click Files & Media.
4. On the Files & Media prompt, click the Gallery tab.
   A sample asset is available on the device and injected into your app. You can use the sample asset or upload your own asset to inject into your app.
5. To upload an asset, click Upload asset, select the asset that you want to upload from your system, and click Open.
   The Files & Media prompt displays the following:
   • The progress bar while the asset is being uploaded. Click Cancel if you want to cancel the current upload and upload another asset.
   • A preview of the asset after the upload is complete.
   • Gallery that displays the uploaded asset.
     You see a message on the dashboard that the asset is uploaded and injected into your app. The latest uploaded asset is injected into your app by default. However, you can select another asset from the gallery to be injected into your app, and click Inject this asset.

In your app, trigger the camera workflow. The injected asset is shown in the camera preview.
