I'm not sure what version of Android you were using but there has been a behavior change to all apps that target Android 9 Pie and above. By default Http requests don't work. Because the request is not made to Log v does not appear in the Logcat. In order to make http network requests you have to specify it in the Android Manifest file. In the application tag add android: usesCleartextTraffic="true". See stack overflow:
