由于友盟更新即将下线，我们就修改了更新逻辑，自己检查更新、下载、安装，但是检查更新还是要依赖于友盟中的在线参数：
1.MainActivity.java:
public class MainActivity extends BaseActivity{
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
CheckUpdateUtil.checkUpdate(this);//检查更新
}
}2.CheckUpdateUtil.java:
package com.monkey.monkeymushroom.util;
import android.app.AlertDialog;
import android.app.NotificationManager;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Environment;
import android.support.v4.app.NotificationCompat;
import android.text.TextUtils;
import android.view.Gravity;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;

import android.widget.TextView;
import android.widget.Toast;
import com.lidroid.xutils.HttpUtils;
import com.lidroid.xutils.exception.HttpException;
import com.lidroid.xutils.http.ResponseInfo;
import com.lidroid.xutils.http.callback.RequestCallBack;
import com.umeng.analytics.MobclickAgent;
import java.io.File;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
/**

public class CheckUpdateUtil {

private static final int UPDATE_ID = "0";
/**

*/
public static boolean checkUpdate(Context context) {
// 获取友盟在线参数（要更新的版本号）
String force_version = MobclickAgent.getConfigParams(context, "version");
if (StringUtils.isEmpty(version)) {
version = "1.0";
}
// 版本号转换为数组
String[] mUpdateVersionArray = version.split(",");
String curr_version_name = SysInfoUtils.getVersionName(context);
for (int i = 0; i < mUpdateVersionArray .length; i++) {//循环获取在线参数上设置的版本号
if (curr_version_name.equals(mUpdateVersionArray [i])) {//如果有，代表要更新
if ((mUpdateVersionArray .length > i + 1) && ("Y".equals(mUpdateVersionArray [i + 1]))) {//判断是否强更
showUpdateDialog(true, context);

//弹框提示
final AlertDialog mAlertDialog = new AlertDialog.Builder(context).create();
mAlertDialog.show();
mAlertDialog.setCancelable(false);
Window window = mAlertDialog.getWindow();
window.setGravity(Gravity.BOTTOM);
window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);

/**

//创建通知栏下载提示

3.更新弹框布局文件dialog_update.xml:
