App Crashes After The Splash Screen Is Loaded

Question

As soon as I am launching my application , the splash screen appears but after 4 seconds the app crashes , I don't know what is the problem . I have already tried and tested other solutions but nothing worked for me. If any of you could tell me the solution then it would be of great help.

Splash.java

package com.example.myapplication;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.os.Handler;
import android.view.WindowManager;

import androidx.annotation.RequiresApi;

import com.example.myapplication.MainActivity;
import com.example.myapplication.R;

public class Splash extends MainActivity {
public static int splashTimeout=2000;
    @RequiresApi(api = Build.VERSION_CODES.P)
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

        new android.os.Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent=new Intent(Splash.this,MainActivity.class);
                startActivity(intent);
                finish();
            }
        } ,splashTimeout );
    }
}

Have you read the stack trace? I presume your theme *isn't* a `NoActionBar` theme and then you're trying to set another one with your `Toolbar`. So you can either do what it tells you to, or use a `NoActionBar` theme if you're using an app compat or material theme. — Henry Twist, Jun 28 '21 at 12:18

You are trying to set action bar with activity twice. remove below line from code or if you do not want to remove below line disable default action bar from activity using theme.

setSupportActionBar(binding.toolbar);

Your logs has your solution.

Add this line

 <item name="windowActionBar">false</item>

to your theme declaration inside of your app/src/main/res/values/styles.xml.

Also, if you're using AppCompatActivity support library of version 22.1 or greater, add this line:

<item name="windowNoTitle">true</item>

Your theme declaration may look like this after all these additions:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>
