Using Android Studio to enable Video recording

Viewed 32

I am using Android studio to make a small App. In one screen, there is a button (button 1) is used to enable the cell phone to start record video. And after recording an AlertDialog is used to replay the video. However, every time when I run on emulator, the app just automatically stopped. Java script of this screen is copied here:

import static android.provider.MediaStore.*;

import androidx.activity.result.ActivityResultCallback;
import androidx.activity.result.ActivityResultLauncher;
import androidx.activity.result.contract.ActivityResultContract;
import androidx.activity.result.contract.ActivityResultContracts;
import androidx.annotation.Nullable;
import androidx.appcompat.app.AppCompatActivity;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.VideoView;

public class Screen3 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_screen3);


        Button button1 = findViewById(R.id.button1);
        Button button2 = findViewById(R.id.button2);


        button1.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View view) {
                Intent intent1 = new Intent(ACTION_VIDEO_CAPTURE);
                intent1.putExtra(EXTRA_DURATION_LIMIT, 5);

                startActivityForResult(intent1, 1);
                }
        }

            );


        button2.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(Screen3.this, MainActivity.class);
                startActivity(intent);
            }

        });

    }


    @Override
    protected void onActivityResult (int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK && requestCode == 1) {
           AlertDialog.Builder builder = new AlertDialog.Builder(this);
            VideoView v1 = new VideoView(this);
            v1.setVideoURI(data.getData());
            v1.start();
             builder.setView(v1).show();
        }

    } 

}

And here is my manifest xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.example.cse535projectpart1">

    <uses-feature android:name="android.hardware.camera" android:required="true" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application
        android:allowBackup="true"
        android:dataExtractionRules="@xml/data_extraction_rules"
        android:fullBackupContent="@xml/backup_rules"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.CSE535ProjectPart1"
        tools:targetApi="31">
        <activity
            android:name=".Screen3"
            android:exported="false" />
        <activity
            android:name=".Screen2"
            android:exported="false" />
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Hopefully someone can give some suggestions how to resolve described issue. Thank you !
