creating an app which showing splash screen 45sec after then movite acitivity

I'd be glad to help you create code for an Android app that displays a splash screen for 45 seconds before transitioning to the main activity. Here's a breakdown using Kotlin, which is the recommended language for modern Android development:

write java code shown in image in mainacititi.java

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent">

<ImageView

android:id="@+id/splash_image"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerInParent="true"

android:src="@drawable/your_splash_image" /> <TextView

android:id="@+id/app_name"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_below="@id/splash_image"

android:layout_centerHorizontal="true"

android:text="@string/app_name"

android:textSize="24sp"

android:textStyle="bold" />

</RelativeLayout>

3. Update Android Manifest:

In your AndroidManifest.xml file, set the android:screenOrientation attribute of the SplashScreenActivity to portrait or landscape to control the splash screen orientation if needed.
Optionally, you can also set the android:theme attribute to a custom theme for the splash screen if you want to apply different styles compared to your main activity.
<manifest ... >
<application ... >
<activity
android:name=".SplashScreenActivity"
android:screenOrientation="portrait"> <intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
