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

まず tns test android と usesCleartextTraffic=false を使って問題を再現し、次に pull request #30 で参照されている AndroidManifest.xml の変更を調査して、アプリケーションのマニフェストの動作と比較します。usesCleartextTraffic=true を本番アプリケーションで必要とせずに Android テストが実行できれば完了です。
