Xin chào, tôi sử dụng đăng nhập Google trong ứng dụng của tôi, nó hoạt động tốt nhưng bất cứ khi nào tôi đăng xuất, tôi đã thử nhiều giải pháp để đăng xuất nhưng không hoạt động đối với tôi và nếu tôi nhấp thêm trên nút đăng nhập Google sau đó ứng dụng gặp sự cố.Lỗi khi đăng nhập lại bằng Google sau khi đăng xuất trong Android
Đây là mã của tôi cho nhập

Bây giờ tôi cần phải signout từ khác sử dụng hoạt động mã này

Phương pháp này doesnt làm việc cho tôi. Thậm chí nếu tôi có sở thích rõ ràng và thử đăng nhập mới với google thì sự cố ứng dụng.
Logcat Lỗi
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.google.android.gms.common.ConnectionResult.hasResolution()' on a null object reference
Cám ơn trả lời. Nhưng nó không làm việc cho tôi. Tôi nghĩ rằng nếu tôi sử dụng các hoạt động khác để đăng xuất, đó là lý do tại sao nó xảy ra. Tôi đã cập nhật mã đăng xuất của mình với toàn bộ hoạt động mà tôi áp dụng mã của bạn ... Có ổn không? – Sam
có đó là tốt ... –
Nhưng nó doesnt làm việc cho tôi, bất cứ khi nào tôi bấm vào nút đăng nhập sau khi đăng xuất sau đó ứng dụng tai nạn với lỗi được xác định ở trên ... – Sam
