Create a true splash screen

Question

How can I make a true splash screen in Android? I don\'t want timers or delays. Just a splash screen that is shown until your application has loaded.

Answer 1

The best way to do a splash screen is:

1. if the user press back, you need to go fast to the main screen.
2. no animation.

I arrived in this good solution:

import android.app.Activity; import android.content.Intent; import android.os.AsyncTask; import android.os.Bundle; import android.view.WindowManager; import br.eti.fml.android.sigame.R;

import java.util.concurrent.atomic.AtomicBoolean;

public class LauncherActivity extends Activity {
    private AsyncTask goingToNextScreen;
    private AtomicBoolean alreadyShown = new AtomicBoolean(false);

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.launcher);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

        //noinspection unchecked
        goingToNextScreen = new AsyncTask() {

            @Override
            protected Object doInBackground(Object... objects) {
                try {
                    Thread.sleep(1500);
                } catch (InterruptedException e) {
                    // ignores
                }

                return null;
            }

            @Override
            protected void onPostExecute(Object o) {
                goNext();
            }
        }.execute();
    }

    @Override
    public void onBackPressed() {
        if (goingToNextScreen != null) {
            goingToNextScreen.cancel(true);

            goNext();
        }
    }

    private void goNext() {
        if (alreadyShown.compareAndSet(false, true)) {
            startActivity(new Intent(LauncherActivity.this, HomeActivity.class));
            overridePendingTransition(0, 0);
            finish();
            overridePendingTransition(0, 0);
        }
    } }
