Issue

Explain your issue. Add any relevant code or stacktraces here.
For some unknown reason Google decided to change the field name but still not fix the patch issue:
https://android.googlesource.com/platform/libcore/+/2496a68/luni/src/main/java/java/net/HttpURLConnection.java#265

    private static final String[] PERMITTED_USER_METHODS = {
        "OPTIONS",
        "GET",
        "HEAD",
        "POST",
        "PUT",
        "DELETE",
        "TRACE"
        // Note: we don't allow users to specify "CONNECT"
     };

    /* valid HTTP methods */
    private static final String[] methods = {
        "GET", "POST", "HEAD", "OPTIONS", "PUT", "DELETE", "TRACE"
    };

Apparently the breaking change by Google is only temporary:
https://android.googlesource.com/platform/libcore/+/refs/heads/master/ojluni/src/main/java/java/net/HttpURLConnection.java#519

    private static final String[] methods = {
        "GET", "POST", "HEAD", "OPTIONS", "PUT", "DELETE", "TRACE"
    };

At some point Google reverted their breaking change.

A try catch must be used rather than checking the Android version since later versions still use the correct method field.
