華為题暖、VIVO、小米梆暮、和其他

• 判斷是否是華為和是否是鴻蒙系統(tǒng)

fun isHuawei():Boolean{
    return ("huawei".equals(Build.BRAND, ignoreCase = true)
                || "huawei".equals(Build.MANUFACTURER, ignoreCase = true))
}

fun isHarmonyOS(): Boolean {
        try {
            val clz = Class.forName("com.huawei.system.BuildEx")
            val method = clz.getMethod("getOsBrand")
            return "harmony" == method.invoke(clz)
        } catch (e: java.lang.Exception) {
            Log.e(
                "TAG",
                "the phone not support the harmonyOS"
            )
        }
        return false
}

• 是否是VIVO

fun isVivo():Boolean{
    return ("vivo".equals(Build.BRAND, ignoreCase = true)
                || "vivo".equals(Build.MANUFACTURER, ignoreCase = true))
}

• 是否是小米

fun isXiaoMi():Boolean{
    return ("xiaomi".equals(Build.BRAND, ignoreCase = true)
                || "xiaomi".equals(Build.MANUFACTURER, ignoreCase = true))
}
