                 if(_active) {
                     waited += 100;
                 }
              }

              // do nothing
           } finally {

               finish();
               startActivity(new Intent("next activity"));
               stop();
           }
        }
     };
     splashThread.start();

Answer 1

It's because you call finish(); before the startActivity(new Intent("next activity"));

Swap finish(); with startActivity(new Intent("next activity"));

Answer 2

Try using this:

SplashScreen.this.finish();

where SplashScreen is the name of the Activity.

Answer 3

It is working in my application

public class Splash extends Activity {
protected boolean _active = true;
protected int _splashTime = 3000;
Thread splashTread;
private boolean stop = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    splashTread = new Thread() {
        @Override
        public void run() {
            try {
                int waited = 0;
                while(_active && (waited < _splashTime)) {
                    sleep(100);
                    if(_active) {
                        waited += 100;
                    }
                }

            } catch(InterruptedException e) {
                // do nothing
            } finally {

                if(!stop){
                    startActivity(new Intent(Splash.this,Home.class));
                    finish();
                }
                else
                    finish();
            }
        }

    };
    splashTread.start();

}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK)) {

        if(splashTread.isAlive())
            this.stop = true;
    }
    return true;
}

}

Answer 4

this solution only solves the problem for the back-button. If users press the home-button the unwanted behavior will still occur. Wouldn't it be easier to overwrite the onStop method and do your thing in there?

@Override
public void onStop(){
    super.onStop();
    if(splashTread.isAlive())
       this.stop = true;
}

Answer 5

public class SplashActivity extends Activity {

    Handler handler;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash_screen);

        handler=new Handler();
        handler.postDelayed(() -> {
            Intent intent=new Intent(SplashActivity.this, Home.class);
            startActivity(intent);
            finish();
        },3000);
    }
}

AndriodManifest.xml

    <activity
        android:name=".SplashActivity"
        android:theme="@style/AppTheme"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
