首先是一个简易的activity

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
	android:background="@android:color/holo_orange_dark" >

    <ProgressBar
        android:id="@+id/pb_bar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:translationY="-50dp"
        android:layout_marginTop="152dp" />

    <TextView
        android:id="@+id/tv_editin"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@android:color/white"
        android:layout_centerInParent="true"
        android:text="版本：" />
    <TextView
        android:id="@+id/tv_editin_edit"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="@android:color/white"
        android:layout_centerVertical="true"
        android:layout_toRightOf="@+id/tv_editin"
        android:text="122.1" />

</RelativeLayout>

下载与安装的工具类，在这个类中要注意的是intent.addCategory("android.intent.category.DEFAULI");这个方法。有时用它会出现找不到intent的现象，可酌情使用

package cnjoanthan.updata;

import java.io.File;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.net.Uri;
import android.os.Environment;
import android.util.Log;
import android.widget.Toast;

/*

 */
public class MyUtils {
	/*
	 * 获取版本号
	 * return 版本号
	 */
	public static String getVersion(Context context){
		PackageManager manager = context.getPackageManager();//PackageManager可以获取文件的信息
		Log.i("VersionUpdateUtils", "manager：" + manager);
		
		try {
			PackageInfo packageInfo = manager.getPackageInfo(context.getPackageName(), 0);
			Log.i("VersionUpdateUtils", "packageInfo：" + packageInfo);
			return packageInfo.versionName;
		} catch (Exception e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
			Log.i("VersionUpdateUtils", "MyUtilsTryAbnormal ：" + e.getMessage());
			return "";
		}
	}
	
	/*
	 * 安装新版本
	 */
	 public static void installApk(Activity activity){
		Log.i("VersionUpdateUtils", "install activity："+activity);
		try {
			String path = Environment.getExternalStorageDirectory().getAbsolutePath()+ File.separator+"mobilesafe"+File.separator+"mobilesafe.apk";
//			String path = "/sdcard/mobilesafe/mobilesafe.apk";
			Intent intent = new Intent();
			
			intent.setAction(Intent.ACTION_VIEW);
			//添加默认分类
//			intent.addCategory("android.intent.category.DEFAULI");
			//设置数据类型
			intent.setDataAndType(Uri.fromFile(new File(path)), "application/vnd.android.package-archive");/* Uri.fromFile(new File(path))*///Uri.parse("file://"+path)
			intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			
			activity.startActivity(intent);
//			activity.startActivityForResult(intent, 0);
			
		} catch (Exception e) {
			// TODO: handle exception
			Log.i("VersionUpdateUtils", "install Excepyion："+e.getMessage());
		}
		
	}	
	 
	

}
