Describe the bug && Reproduction
I'm experiencing the same issue outlined in #4119.

Run tns test android with usesCleartextTraffic=false, the test app shows "no reachable hosts". Setting usesCleartextTraffic=true allows the tests to execute.

I don't want to set usesCleartextTraffic to true with my production application, so I'm wondering how I get around this.

Expected behavior
I expect the tests to run 😄

Additional context
This was supposed to be resolved with this pull request. I see that there is an AndroidManifest.xml file in those changes, and I'm wondering if that is supposed to override the settings in my application's manifest

package.json

先使用 tns test android 和 usesCleartextTraffic=false 重現問題，接著檢查 pull request #30 中參照的 AndroidManifest.xml 變更，並將其與應用程式的資訊清單行為進行比較。當 Android 測試不需要在正式應用程式中要求 usesCleartextTraffic=true 即可執行時，即表示完成。
