Android WebView Post Request with Custom Headers

Question

I could see there are two separate methods in Android docs to post the data and add the headers.

For setting Headers
public void loadUrl (String url, Map

        

Answer 1

It seems that the framework does not provide these features together.

Looking at the source code of WebViewCore (https://android.googlesource.com/platform/frameworks/base/+/eclair-release%5E2/core/java/android/webkit/WebViewCore.java, line 889), additional headers are processed only in the loadUrl call and never in the postUrl.
