Android获取唯一设备ID解决方案

Android 获取唯一设备ID的方法挺多。但是都不完美，要不就是有的会随着恢复出厂设置改变。要不就是不是唯一，再或者取不到。这里把Android_id,SerialNumber和UniquePsuedoID结合在一起写了一个工具类。暂未发现取不到或者不唯一的情况
另包含获取设备常用信息的方法

直接上代码

public class CarOnlyIdUtils {
    public static String getANDROID_ID(Context context){
        String ANDROID_ID="";
        try {
            ANDROID_ID = Settings.System.getString(context.getContentResolver(), Settings.System.ANDROID_ID);
            if(TextUtils.isEmpty(ANDROID_ID)){
                return "";
            }
        }catch (Exception e){
            return "";
        }

        return  ANDROID_ID;
    }


    public static String getSerialNumber(){

                return "";
            }
