换3.1试试，输入法已完全重写

[qingqingcaoyuanlin]

已经切换了3.1.0版本，跑用例遇到个异常，adbutils版本是2.7.2，以下日志是pytest打印出来的：
2024-06-05 12:00:02 api.py:40 [WARNING]: broadcast ADB_KEYBOARD_CLEAR_TEXT failed: error:Attempt to read from field 'java.lang.CharSequence android.view.inputmethod.ExtractedText.text' on a null object reference, retrying in 1 seconds...

感觉好像是在空的输入框内调用了clear_text，下方是一些一些错误日志：
