The application is installed but not running or visible on virtual device

Issue

[2013-05-17 03:56:29 - beginner] Android Launch!
[2013-05-17 03:56:29 - beginner] adb is running normally.
[2013-05-17 03:56:29 - beginner] No Launcher activity found!
[2013-05-17 03:56:29 - beginner] The launch will only sync the application package on the device!
[2013-05-17 03:56:29 - beginner] Performing sync
[2013-05-17 03:56:29 - beginner] Automatic Target Mode: using existing emulator 'emulator-5554' running compatible AVD 'wlah'
[2013-05-17 03:56:30 - beginner] Application already deployed. No need to reinstall.
[2013-05-17 03:56:30 - beginner] \beginner\bin\beginner.apk installed on device
[2013-05-17 03:56:30 - beginner] Done!

I don't know why this is happening. The AVD was running my apps a few days ago. But now it's just displaying this message on the Console but the application is not actually installed in the AVD (or the emulator).

Solution

Application installed but you didn't mention the launcher activity
Modify Your Manifest File :-

  <application android:icon="@drawable/icon" android:label="@string/app_name">
            <activity android:name=".YourActivity">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
            </activity>
    </application>

Update:

This :

<action android:name="android.intent.action.SPLASHACTIVITY" />

To:

<action android:name="android.intent.action.MAIN" />
