我在我的Android应用程序中运行后台服务.我使用从登录活动中获取的IdToken在后端服务器上进行身份验证.该服务正在START_STICKY模式下运行,因此即使应用程序关闭,该服务仍会在后台运行以从后端服务器获取任何通知.我面临的问题是当IdToken过期时,我无法在服务中更新它.如果令牌已过期,则回调函数不会收到任何结果.如果令牌尚未过期,它会立即获得结果.

这是signIn函数和handleSignIn函数的代码.

private void signIn() {
        new Thread(new Runnable() { public void run() {
        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

                .build();
        GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(context)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                .build();

        OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn
                (mGoogleApiClient);
        if (opr.isDone()) {
            // If the user's cached credentials are valid, the OptionalPendingResult will be "done"

            // and the GoogleSignInResult will be available instantly.
            Log.d(TAG, "Got cached sign-in");
            GoogleSignInResult result = opr.get();
            handleSignInResult(result);
        } else {
            // If the user has not …
