@nativescript/google-signin Configure Placement

From the comment and past experiences I figured the configure method needed to be called in main.ts.

Also be sure you have called configure in main.ts (or app.ts depending on project type), eg:

import { GoogleSignin } from '@nativescript/google-signin';

GoogleSignin.configure();

This results in a error
GoogleSignin configuration error: Error: java.lang.NullPointerException: Parameter specified as non-null is null: method kotlin.jvm.internal.Intrinsics.checkNotNullParameter, parameter activity

and a GoogleSignin.signIn() error of
.signIn Error: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.content.Intent.migrateExtraStreamToClipData(android.content.Context)' on a null object reference

Putting the configure in a component or service after main.ts, still ensuring it's called only once, fixes this but it conflicts with @NathanWalker's recommendation

Issue に記載されているエントリポイント main.ts/app.ts と @nativescript/google-signin の configure および signIn 呼び出しから始めます。壊れている例をリンク先の動作する pull request と比較し、推奨されるエントリポイントから設定することで Android エラーが発生しなくなり、signIn が成功することを確認します。
