Camera open capture video and show video view in android java

To open the camera, capture video, and show the video view in Android Java, you can follow these steps:

1:Add necessary permissions to the AndroidManifest.xml file:

xml
<uses-permission android:name="android.media.action.VIDEO_CAPTURE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

3. 
   
4. Create a layout for the video view in XML:

xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="@color/white"
    tools:context=".videocpaturecode">
<Button
    android:layout_width="match_parent"
    android:id="@+id/btn_open_camera"
    android:layout_gravity="center"
    android:textSize="20dp"
    android:gravity="center"
    android:layout_height="wrap_content"
    android:text="open Camera"/>

<VideoView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/Captire_video_show"/>
</LinearLayout>

4. In your activity or fragment, set up the camera and start the capture session:
