Android Studio – app keeps stopping error on Android Studio

I’m designed an application on Figma and I get the assets via using extension for Android Studio. After that, I’m created a "no activity" from Android Studio, using API 33.

Whatever, Figma plug-in that is "export kit" created a zip file. It contains a java folder, a res folder and "AndroidManifest.xml". When I open the project and follow the "res > layout > login_page_activity.xml" it comes as layout to right side panel. But when I run the application with emulator; the application builded but after start process it suddenly stopped and there was a crash like "Weesi keeps stopping". I can’t get the view that I designed on figma. Can anyone help? I’m sharing codes and screenshots.

package exportkit.figma;

import android.app.Activity;
import android.os.Bundle;


import android.view.View;
import android.widget.ImageView;

public class login_page_activity extends Activity {

    
    private View _bg__login_page;
    private ImageView vector;
    private ImageView vector_ek1;
    private ImageView vector_ek2;
    private ImageView vector_ek3;
    private ImageView vector_ek4;
    private ImageView vector_ek5;
    private ImageView vector_ek6;
    private View rectangle_1;
    private ImageView mask_group;
    private ImageView vector_ek7;
    private ImageView mask_group_ek1;
    private ImageView vector_ek8;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.login_page);

        
        _bg__login_page = (View) findViewById(R.id._bg__login_page);
        vector = (ImageView) findViewById(R.id.vector);
        vector_ek1 = (ImageView) findViewById(R.id.vector_ek1);
        vector_ek2 = (ImageView) findViewById(R.id.vector_ek2);
        vector_ek3 = (ImageView) findViewById(R.id.vector_ek3);
        vector_ek4 = (ImageView) findViewById(R.id.vector_ek4);
        vector_ek5 = (ImageView) findViewById(R.id.vector_ek5);
        vector_ek6 = (ImageView) findViewById(R.id.vector_ek6);
        rectangle_1 = (View) findViewById(R.id.rectangle_1);
        mask_group = (ImageView) findViewById(R.id.mask_group);
        vector_ek7 = (ImageView) findViewById(R.id.vector_ek7);
        mask_group_ek1 = (ImageView) findViewById(R.id.mask_group_ek1);
        vector_ek8 = (ImageView) findViewById(R.id.vector_ek8);
    
        
        //custom code goes here
    
    }
}

This usage generates error. So I’m adding the following package;

import "com.example.weesi.R";

It solves. But in this sittuation the big problem is when I click the run on emulator, It gives error that is in the picture;

enter image description here

This is logcat error.

    I think you are not registering Activity in AndroidManifest.xml

    Please add your Activity in your AndroidManifest.xml

    try this code,

    <activity
    android:name="com.example.weesi.login_page_activity"
    android:configChanges="orientation|keyboardHidden|screenSize"
    android:label="@string/app_name"
    android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
</activity>

    Update activity tag in your manifest.

    You should add your activities to the "AndroidManifest.xml" file. Add like this

    <activity android:name="YOUR_ACTIVITY" android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
    <meta-data android:name="android.app.lib_name" android:value=""/>
</activity>

    Then run app again. Then your problem will be solved!
