Android 13 USB调试加密

介绍

客户需要开发者模式开启时，打开USB调试需要加入密码显示，我们的思路是在打开USB调试时弹出的弹框下方加入输入密码框。

效果展示

修改

字符串资源

路径：vendor/mediatek/proprietary/packages/apps/MtkSettings/res/values/strings.xml

    <string name="student_password_error">wrong password</string>
    <string name="student_hint_passwork">Please enter your password</string>

路径：vendor/mediatek/proprietary/packages/apps/MtkSettings/res/values-zh-rCN/strings.xml

    <string name="student_password_error">密码错误</string>
    <string name="student_hint_passwork">请输入密码</string>

我们通过相关字符串找到了弹框出现的代码?onCreateDialog

实际上代码中的布尔值studentSwitch 是动态的来开关这个功能 如果不需要可以默认写成true

String password 实际上就可以自定义成自己想要的密码
