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:

   private static NotificationManager manager;    private static final int UPDATE_ID = "0";    /**     * 检查更新     *     * @param context     * @return     */    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);                } else {//不强更                    showUpdateDialog(false, context);                }                return true;// 只要找到对应的版本号，即有更新，结束循环            }        }        return false;//无更新    }    /**     * 显示更新对话框     *     * @param isForceUpdate 是否强制更新     */    public static void showUpdateDialog(final boolean isForceUpdate, final Context context) {        // 获取更新日志        String update_log = MobclickAgent.getConfigParams(context, "update_log");        // 最新版本        String new_version = MobclickAgent.getConfigParams(context, "new_version");        // 获取下载地址        final String download_path = MobclickAgent.getConfigParams(context, "new_version_path");        if (TextUtils.isEmpty(update_log) || TextUtils.isEmpty(download_path) || TextUtils.isEmpty(new_version)) {            return;        }        LogMessage.e("monkey", "更新日志--> " + update_log + " 最新版本--> " + new_version + " 下载地址--> " + download_path);        //弹框提示        final AlertDialog mAlertDialog = new AlertDialog.Builder(context).create();        mAlertDialog.show();        mAlertDialog.setCancelable(false);        Window window = mAlertDialog.getWindow();

               mAlertDialog.dismiss();            }        });        notNow.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                mAlertDialog.dismiss();

                       ToastUtil.show(context, "正在下载……");                        //创建通知栏下载提示                        builder = new NotificationCompat.Builder(context);                        builder.setSmallIcon(R.drawable.ic_launcher)                                .setOngoing(true)                                .setContentTitle("猴菇先生");                        manager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);                    }                    @Override                    public void onLoading(long total, long current, boolean isUploading) {                        super.onLoading(total, current, isUploading);                        LogMessage.e("monkey", "--> total " + total + " current " + current);                        int cur = (int) (current * 100 / total);                        LogMessage.e("monkey", "cur--> " + cur + "%");                        builder.setProgress(100, cur, false)//更新进度                                .setContentText(cur + "%");                        manager.notify(UPDATE_ID, builder.build());                    }                    @Override                    public void onSuccess(ResponseInfo<File> responseInfo) {                        manager.cancel(UPDATE_ID);//取消通知栏下载提示                        //下载成功后自动安装apk并打开                        File file = responseInfo.result;

3.更新弹框布局文件dialog_update.xml:

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <RelativeLayout        android:layout_width="310dp"        android:layout_height="wrap_content"        android:layout_centerInParent="true"        android:background="@color/base_white"        android:paddingBottom="20dp">        <TextView            android:id="@+id/title"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_centerHorizontal="true"            android:layout_marginBottom="20dp"            android:layout_marginTop="20dp"            android:text="发现新版本"            android:textSize="20sp" />        <View            android:id="@+id/line"            android:layout_width="match_parent"            android:layout_height="1dp"            android:layout_below="@+id/title"            android:background="#4a7acd" />        <TextView            android:id="@+id/log_head"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_below="@+id/line"            android:layout_marginLeft="20dp"            android:layout_marginTop="20dp" />        <TextView            android:id="@+id/msg_tv"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_below="@+id/log_head"            android:layout_centerHorizontal="true"            android:layout_marginLeft="32dp"            android:layout_marginRight="32dp"            android:text="更新日志"            android:textSize="16sp" />        <LinearLayout            android:layout_width="match_parent"            android:layout_height="35dp"            android:layout_below="@+id/msg_tv"            android:layout_marginTop="30dp"            android:orientation="horizontal">            <Button                android:id="@+id/yes_btn"                android:layout_width="0dp"                android:layout_height="35dp"                android:layout_marginLeft="20dp"                android:layout_marginRight="20dp"                android:layout_weight="1"                android:background="#4a7acd"                android:gravity="center"                android:text="立即更新"                android:textColor="@color/base_white"                android:textSize="16sp" />            <Button                android:id="@+id/no_btn"                android:layout_width="0dp"                android:layout_height="35dp"                android:layout_marginRight="20dp"                android:layout_weight="1"                android:background="#4a7acd"                android:gravity="center"                android:text="以后再说"                android:textColor="@color/base_white"                android:textSize="16sp" />        </LinearLayout>    </RelativeLayout></RelativeLayout>
