Android camera application tutorial: only supports the front camera function

In this tutorial, I will show you how to remove the rear camera support in the Android camera application, leaving only the front camera functionality. We will use the Java programming language and the Android camera API to achieve this.

Step 1: Create a new Android project
First, let's create a new Android project. Open Android Studio and select "Create New Project". Follow the wizard's instructions to create a new project.

Step 2: Set camera permissions
In the AndroidManifest.xml file, make sure to add camera permissions. Add the following permissions under the label:

<uses-permission android:name="android.permission.CAMERA" />

Step 3: Set the layout file
Open the res directory and find the activity_main.xml file. In this file, we will add a preview view to display the image from the front camera.
