即使进行了正确的检查，我仍然不赞成使用API​​警告 [英] I keep getting deprecated API warning even with correct check

问题描述

我正在开发一个Android项目，在代码中的某个点上，我需要获取设备序列号。

I'm working on a Android project, and at some point in my code I need to get the device serial number.

为了获得它，我使用了使用 Build.SERIAL （自Android O 开始不推荐使用）。为了避免出现问题，我开始使用 Build.getSerial（），并创建了一个包装操作系统版本检查的小方法：

In order to get it I used to use Build.SERIAL which has been deprecated since Android O. To avoid problems I started using Build.getSerial(), and created a little method that wraps up the OS version check:

private static String getSerial() throws SecurityException {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.O) {
        return Build.SERIAL;
    }

    return Build.getSerial();
}

注意：我不是在检查权限 READ_PHONE_STATE （ getSerial（）方法要求），因为我从一开始就在做，并确保已经拥有<

Note: I'm not checking for the permission READ_PHONE_STATE (required by the getSerial() method) to be granted because I'm doing it at the start and make sure I already have it before getting to this method.

问题是，无论我如何写下Android OS检查，我都会不断收到过时的API警告。

The problem is that, no matter how I write down the Android OS check I keep getting the deprecated API warning.

我尝试了以下操作，对于所有可能的版本，我都会在 Build.SERIAL

I tried the following and for all possible versions I keep getting the warning on Build.SERIAL

private static String getSerial() throws SecurityException {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        return Build.getSerial();
    }
    return Build.SERIAL;
}

private static String getDeviceUDI() throws SecurityException {
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        return Build.getSerial();
    } else {
        return Build.SERIAL;
    }
}

private static String getDeviceUDI() throws SecurityException {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.O) {
        return Build.SERIAL;
    } else {
        return Build.getSerial();
    }
}

推荐答案

您需要这样的东西：

@SuppressLint("HardwareIds")
@SuppressWarnings("deprecation")
private static String getSerial() throws SecurityException {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.O) {
        return Build.SERIAL;
    }
    return Build.getSerial();
}
