Upgraded to 14.04 reboot fail

Question

I have a working splashscreen activity. However, if user hits back button, and after resume the application again, i don't want to show splashscreen. How can I do that ?

SplashScreen.java

public class SplashScreen extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        Thread t = new Thread() {
            public void run() {
                try {
                    int time = 0;
                    while (time < 4000) {
                        sleep(100);
                        time += 100;
                    }
                }
                catch (InterruptedException e) {
                    // do nothing
                }
                finally {

                    Intent i = new Intent(SplashScreen.this, MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }
        };
        t.start();

    }
}

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    <activity android:name=".MainActivity"
            android:label="@string/app_name"
            android:launchMode="singleInstance"
            android:alwaysRetainTaskState="true"
            android:icon="@mipmap/ic_launcher"
            android:screenOrientation="portrait"
            android:theme="@style/AppTheme">
        </activity>

    </application>

</manifest>

Solution

I had the same problem this morning, after my 13.10 to 14.04 upgrade last night. My setup is a dual boot with Windows, using the windows boot manager.

I found the solution here: same issue with Win 8

The precis is:

1. When I select Ubuntu from the boot manager, I hold the shift key
2. This brings up Grub manager
3. With the first line selected, hit "e" (for edit)
4. Hunt down through the boot instructions to a long command line that includes options "ro quiet splash"
5. Change the "ro" to "rw" (readonly to read-write)
6. ctl-x to save and run

This brought me right up in 14.04 LTS. The disclaimer is that I don't have any idea why it worked. I then edited /boot/grub.cfg to make this same change permanent (suggestions on the correct way to do this appreciated).

This solved the problem, I see the desktop but it keeps loading without entering Ubuntu environment

store your splash screen state in shared pref and check it in onCreate of the spalsh screen and if user already visited it simply navigate to homescreen

well dang, I have no idea how you figured that out, but it works! I was on wubi if that makes any difference...

Tried both of the methods, it still shows the splash :/
