I implemented a splash screen to launch before my main activity. Before I put the Splash Screen, it worked. I am not sure where I am going wrong or what I missed.

This is my code

 Splashscreen.java : package pens.pensnews;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.view.Window;import android.view.WindowManager; public class Splashscreen extends Activity { //Set waktu lama splashscreen private static int splashInterval = 2000; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.activity_splashscreen); new Handler().postDelayed(new Runnable(){ @Override public void run() { // TODO Auto-generated method stub Intent i = new Intent(getApplicationContext(), MainActivity.class); startActivity(i); // menghubungkan activity splashscreen ke main activity dengan intent //jeda selesai Splashscreen finish(); } }, splashInterval); }} MainActivity.java package pens.pensnews;import android.os.Bundle;import android.support.design.widget.FloatingActionButton;import android.support.design.widget.Snackbar;import android.support.v4.app.FragmentManager;import android.support.design.widget.NavigationView;import android.support.v4.view.GravityCompat;import android.support.v4.widget.DrawerLayout;import android.support.v7.app.ActionBarDrawerToggle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.Menu;import android.view.MenuItem;import android.view.View; public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle( this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); drawer.setDrawerListener(toggle); toggle.syncState(); NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); FragmentManager manager = getSupportFragmentManager(); Kampus kampus = new Kampus(); manager.beginTransaction().replace(R.id.MainLayout, kampus).commit(); Akademik akademik = new Akademik(); manager.beginTransaction().replace(R.id.MainLayout, akademik).commit(); Nonak nonak = new Nonak(); manager.beginTransaction().replace(R.id.MainLayout, nonak).commit(); Beranda beranda = new Beranda(); manager.beginTransaction().replace(R.id.MainLayout, beranda).commit(); } @Override public void onBackPressed() { DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); if (drawer.isDrawerOpen(GravityCompat.START)) { drawer.closeDrawer(GravityCompat.START); } else { super.onBackPressed(); }} @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.

Answer 1

Add This line in your AndroidManifest.xml

android:theme="@style/AppTheme.NoActionBar"

after adding this line your file look like this..

 <activity
            android:name="pens.pensnews.Splashscreen"
    android:label="@string/app_name"
            android:theme="@style/Splashscreen"
    android:theme="@style/AppTheme.NoActionBar"
            android:noHistory="true">
            <intent-filter>
    <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
    </activity>

Shiena if this code is work for you then mark this question as your answer.
