Splash screen at the beginning of app

Question

I need some help. I have a problem with my app. I want to put a splash screen at the beginning. I have done it before. I have made the code, the layout, and all works perfectly in a new project! When I put the code I run it on my phone and the layout in my application, the application runs perfectly without any errors. But when I open it on my phone, it stops and it doesn't open it!!! Can you suggest something??

my android manifest.xml:

        android:name=".activities.SplashScreenActivity"
        android:label="@string/splash">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

Answer 1

Assuming you want to launch Main activity from your SplashScreenActivity.

In your SplashScreenActivity's onCreate():

Intent intent = new Intent(SplashScreenActivity.this, MainActivity.class);
startActivity(intent);
finish();

The first 2 lines launch Main activity through an Intent, and the 3rd line kills SplashScreenActivity so you cannot go back to it from MainActivity.

Answer 2

public class SplashScreenActivity extends AppCompatActivity {
private  int SLEEP_TIMER = 3;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    setContentView(R.layout.activity_splash_screen);

    View imageView = findViewById(R.id.imageView);

    Animation animation = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.fade);

    imageView.startAnimation(animation);
    getSupportActionBar().hide();
    LogoLauncher logoLauncher = new LogoLauncher();
    logoLauncher.start();


}

private class LogoLauncher extends Thread {
    public void run() {
        try {
            sleep(1000  * SLEEP_TIMER);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        Intent intent = new Intent(SplashScreenActivity.this,LoginActivity.class);
        startActivity(intent);
        SplashScreenActivity.this.finish();
    }
}
