How do I make a splash screen? [closed]

Answer 1

How about a super-flexible launch screen that can use the same code and is defined in the AndroidManifest.xml, so the code will never need to change. I generally develop libraries of code and do not like customizing code because it is sloppy.

Then the SpashActivity itself looks up the meta-data for "launch_class" to then make the Intent itself. The meta data "duration" defines how long the splash screen stays up.

public class SplashActivity extends Activity {

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.activity_splash);

    ComponentName componentName = new ComponentName(this, this.getClass());

    try {
        Bundle bundle = null;
        bundle = getPackageManager().getActivityInfo(componentName, PackageManager.GET_META_DATA).metaData;
        String launch_class = bundle.getString("launch_class");
        //default of 2 seconds, otherwise defined in manifest
        int duration = bundle.getInt("duration", 2000);

        if(launch_class != null) {
            try {
                final Class c = Class.forName(launch_class);

                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        Intent intent = new Intent(SplashActivity.this, c);
                        startActivity(intent);
                        finish();
                    }
                }, duration);

            } catch (ClassNotFoundException e) {
                e.printStackTrace();
            }
        }
    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
  }
}
