Didn't find class "android.security.NetworkSecurityPolicy" on path: DexPathList

Hi

Getting this on Android 5.1.1, 3.4.2. Removing the handler and reverting to the built in version works.

Didn't find class \"android.security.NetworkSecurityPolicy\" on path: DexPathList[[zip file

Any ideas?

Same problem here.

Looks like is related with isCleartextTrafficPermitted use in OkHttp (https://github.com/square/okhttp/issues/3772).

OkHttp team fix it in 3.12 version but this release requires Android >= 23 so it's nood good solution for us.

Same problem here. Team OkHttp fixed this issue. Some of our devices under API 23 cannot use currently ModernHttpClient. We would love to see this fix as soon as possible in ModernHttpClient.

I had this error too on android 5. I used the commit #61 provided by @SlyNet and the problem solved (tested with android versions 4.4, 5, 7.1 and 9).

Square.OkHttp3 version 3.12.x supports older android versions and they'll continue to update it until 31/12/2020 as they say on their readme.

The OkHttp 3.12.x branch supports Android 2.3+ (API level 9+) and Java 7+. These platforms lack support for TLS 1.2 and should not be used. But because upgrading is difficult we will backport critical fixes to the 3.12.x branch through December 31, 2020. From 3.13.+ it only supports android 5+.

I tried modernhttpclient with updated reference of OKHttp to version 3.12.6 and it worked fine on android versions 4.4, 5, 7.1 and 9.

@alexrainman whenever you have time, please take a look on #61 Thanks

[alexrainman]

Will do.

[jded76]

Are you planning releasing the new version on nuget so I can tested it?

[alexrainman]

Yes.
