title: generated signed apk according to the documentation of react-native but it does not appear on my device
body: <p>I've developed my first RN application and generated the apk as the react-native's documentation says and everything is fine, it does not show me any error, but when I install the apk in an emulator or on my smartphone the application does not appear anywhere, if I get into all applications to uninstall my application previously installed it is there but when I'm going to use it does not appear any icon or whatever. Any idea why I can not see my app? I used <em>detach</em> (Expo SDK)</p>
