使用这个类

import android.os.Build;

/**
 * Created by MOMANI on 2016/04/14.
 */
public class AndroidVersionUtil {
    public static int getApiVersion() {
        return android.os.Build.VERSION.SDK_INT;
    }

    public static boolean isApiVersionGraterOrEqual(int thisVersion) {
        return android.os.Build.VERSION.SDK_INT >= thisVersion;
    }
}

使用这种方法:

 public static String getAndroidVersion() {
        String versionName = "";

        try {
             versionName = String.valueOf(Build.VERSION.RELEASE);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return versionName;
    }

if (Build.VERSION.SDK_INT >= ApiHelper.VERSION_CODES.HONEYCOMB_MR2) {
//do anything you  like.
}

你可以在Build.VERSION中找到Android版本。

文档建议您检查Build.VERSION。SDK_INT对应Build.VERSION_CODES中的值。

这很好，只要你意识到Build.VERSION。SDK_INT只在API Level 4中引入，也就是Android 1.6 (Donut)。所以这不会影响你，但如果你想让你的应用在Android 1.5或更早的版本上运行，那么你必须使用已弃用的Build.VERSION.SDK。

使用这个类

import android.os.Build;

/**
 * Created by MOMANI on 2016/04/14.
 */
public class AndroidVersionUtil {
    public static int getApiVersion() {
        return android.os.Build.VERSION.SDK_INT;
    }

    public static boolean isApiVersionGraterOrEqual(int thisVersion) {
        return android.os.Build.VERSION.SDK_INT >= thisVersion;
    }
}

如果你的android设备上有bash，你可以使用这个bash函数:

function androidCodeName {
    androidRelease=$(getprop ro.build.version.release)
    androidCodeName=$(getprop ro.build.version.codename)

    # Time "androidRelease" x10 to test it as an integer
    case $androidRelease in
        [0-9].[0-9]|[0-9].[0-9].|[0-9].[0-9].[0-9])  androidRelease=$(echo $androidRelease | cut -d. -f1-2 | tr -d .);;
        [0-9].) androidRelease=$(echo $androidRelease | sed 's/\./0/');;
        [0-9]) androidRelease+="0";;
    esac

    [ -n "$androidRelease" ] && [ $androidCodeName = REL ] && {
    # Do not use "androidCodeName" when it equals to "REL" but infer it from "androidRelease"
        androidCodeName=""
        case $androidRelease in
        10) androidCodeName+=NoCodename;;
        11) androidCodeName+="Petit Four";;
        15) androidCodeName+=Cupcake;;
        20|21) androidCodeName+=Eclair;;
        22) androidCodeName+=FroYo;;
        23) androidCodeName+=Gingerbread;;
        30|31|32) androidCodeName+=Honeycomb;;
        40) androidCodeName+="Ice Cream Sandwich";;
        41|42|43) androidCodeName+="Jelly Bean";;
        44) androidCodeName+=KitKat;;
        50|51) androidCodeName+=Lollipop;;
        60) androidCodeName+=Marshmallow;;
        70|71) androidCodeName+=Nougat;;
        80|81) androidCodeName+=Oreo;;
        90) androidCodeName+=Pie;;
        100) androidCodeName+=ToBeReleased;;
        *) androidCodeName=unknown;;
        esac
    }
    echo $androidCodeName
}
