设备检测工具类

蓝牙检测，需要用到以下权限：

    <!-- 如果需要访问蓝牙设备，可能需要以下权限 --><uses-permission android:name="android.permission.BLUETOOTH" /><uses-permission android:name="android.permission.BLUETOOTH_ADMIN" /><!-- 对于 Android 12 及以上，可能需要声明使用蓝牙扫描的权限 --><uses-permission android:name="android.permission.BLUETOOTH_SCAN" /><uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

调用示例：

 private fun showCompatibilityDetails() {val deviceChecker = DeviceChecker(this)if (deviceChecker.isDeviceCompatible()) {Toast.makeText(this, "设备满足所有要求", Toast.LENGTH_LONG).show()} else {Toast.makeText(this, "设备不满足要求，请检查硬件和软件配置", Toast.LENGTH_LONG).show()// 可选：显示具体哪些不满足val details = StringBuilder()details.append("设备兼容性详情:\n")details.append("CPU: ${if (deviceChecker.isCpuCompatible()) "满足" else "不满足"}\n")details.append("RAM: ${if (deviceChecker.isRamCompatible()) "满足" else "不满足"}\n")details.append("ROM: ${if (deviceChecker.isRomCompatible()) "满足" else "不满足"}\n")details.append("蓝牙: ${if (deviceChecker.isBluetooth4Supported()) "满足" else "不满足"}\n")details.append("屏幕尺寸: ${if (deviceChecker.isScreenSizeCompatible()) "满足" else "不满足"}\n")details.append("屏幕分辨率: ${if (deviceChecker.isScreenResolutionCompatible()) "满足" else "不满足"}\n")details.append("Android 版本: ${if (deviceChecker.isAndroidVersionCompatible()) "满足" else "不满足"}\n")// 显示详情（例如通过对话框）// 这里简单使用 Toast，实际项目中建议使用 AlertDialog 或自定义布局Log.w("caowj", "判断结果：$details")}}
