Error: No Launcher activity found!
The launch will only sync the application package on the device!
Android emulator not showing the app
Workaround:
Check AndroidManifest.xml for MAIN and LAUNCHER. MyActivity.java is first Activity what will opened if .apk is installed.

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