Android 版本升级实现

项目中版本更新是不可或缺的功能

0x00配置Config

这里主要配置的是4个final属性 还有的就是获取新版信息的路径,返回的是一个json 如

{"version":{"apkname":"Tjrac_lib.apk","appname":"Tjrac_lib","verCode":"2","verName":"1.0.1"}}

然后存放新版apk在UPDATE_APKNAME路径上~

import com.tjrac.R;

import android.content.Context;
import android.content.pm.PackageManager.NameNotFoundException;
import android.util.Log;

public class Config {
private static final String TAG = "Config";
/**
 * 服务器存放的apk路径
 */
public static final String UPDATE_SERVER = "http://192.168.0.101:8080/NFC_Library/";

/**
 * 新版apk存在服务器的路径和名称
 */
public static final String UPDATE_APKNAME = "Tjrac_lib.apk";

/**
 * 获取版本信息的访问路径
 */
public static final String UPDATE_VERJSON = "LIB/LIB_AndroidUser_Version_Update";

/**
 * 保存在sdk内的新版apk名称
 */
public static final String UPDATE_SAVENAME = "Tjrac_lib.apk";

public static int getVerCode(Context context) {
    int verCode = -1;
    try {
        verCode = context.getPackageManager().getPackageInfo(
                "com.tjrac", 0).versionCode;
        System.out.println("版本号为 : "+verCode);
    } catch (NameNotFoundException e) {
        Log.e(TAG, e.getMessage());
    }
    return verCode;
}

public static String getVerName(Context context) {
    String verName = "";
    try {
        verName = context.getPackageManager().getPackageInfo(
                "com.tjrac", 0).versionName;
        System.out.println("版本名称为 : "+verName);
    } catch (NameNotFoundException e) {
        Log.e(TAG, e.getMessage());
    }
    return verName;
}

public static String getAppName(Context context) {
    String verName = context.getResources().getText(R.string.app_name)
            .toString();
    return verName;
}
}

0x01 更新操作类 Update

getServerVerCode():获取新版本信息 Select_Version():比较新旧版本号 notNewVersionShow():版本号一致无需更新 doNewVersionUpdate():更新版本 downFile(final String url):下载新版本 down():下载完成,取消提示框 update():安装新版本

调用更新方法

在当前的activity中

Update update =new Update(Sy_Activity.this);
update.getServerVerCode();
