Nativescript: HTTP failure response for unknown URL

问题

I have a situation, I have pulled the latest changes from my branch and trying to run the application using tns run android command. The app is launched successfully but the API call is restricted throwing an error as soon as the app starts.

I have also gone through this answer but that's not the problem it seems. Because for other team members it is working fine. :/

回答1:

Starting with Android 9.0 (API level 28), cleartext support is disabled by default.

Update your manifest file with the android:usesCleartextTraffic flag.

<application ... android:usesCleartextTraffic="true" ...>

回答2:

Go to: your-project\App_Resources\Android\src\main\AndroidManifest.xml

Update your manifest by adding android:usesCleartextTraffic="true" to existing rules in <application></application> tag, like as seen bellow

<application
    ...
    ...
    android:usesCleartextTraffic="true">
    ...
    ...
</application>
