Bàn phím Android (AOSP) liên tục dừng với trình giả lập Android O

Question

Tôi đang gặp sự cố này khi sử dụng bàn phím Android với trình giả lập Android O. Nó luôn luôn mang lại cho tôi những lỗi nói

"Bàn phím Android (AOSP) đã ngừng"

khi tôi đang cố gắng để bấm nút "? 123" từ bàn phím Android, và sau đó là bàn phím tự đóng.

Sự cố này chỉ xảy ra khi tôi đang sử dụng trình mô phỏng với API 26 (Android O) trong Android Studio 3.0 Canary 7. Dán thông báo lỗi vào phần sau.

Đây có phải là lỗi từ phía Android O không?

Answer 1

Đây là lỗi trong phương thức nhập LatinIME trong AOSP 8.0 (có thể họ không phát hiện ra nó vì bàn phím AOSP không được sử dụng trong Android mang thương hiệu).
