[Android][.Net 4.6] HTTPClient.GetAsync fails to get address with unable to find libc error



To reproduce:

1. Download and open attached "" project.
2. Enter play mode and notice Debug.log statements printed out.
3. Exit play mode.
4. Build and run with android device connected.
5. Use logcat to see application logs.
6. Notice that logs differ. Connection error appears.

Expected result: Everything works the same as in the editor. Connection to client address succeeds.
Actual result: "Unable to find libc" error appears. Connection doesn't succeed.

Reproduced with: 2017.3.0a2, 2017.2.b5, 2017.1.0p2.

Devices under test:

Samsung SM G925F (Galaxy S6 Edge)*, OS:7.0, CPU:arm64-v8a, GPU:Mali-T760,

Google Nexus 6*, OS:6.0.1, CPU:armeabi-v7a, GPU:Adreno (TM) 420,

Sony C6603 (Xperia Z)*, OS:5.1.1, CPU:armeabi-v7a, GPU:Adreno (TM) 320,

Notes: Feature works only with .Net 4.6. On standalone everything works correctly. On iOS some of the logs seems to be missing but no there are no errors printed.

Verified with: 2018.2.0a1, 2018.1.0b7, 2017.3.1p1, 2017.2.1p4

For fix to work, in Player settings "Internet Access" property must be set to Require. Also "Unable to find libc" error can still be seen in the logcat, thus the initial problem that connection did not succeed was fixed.
