爱华网因为应用程序的安装与卸载模块在android系统中已经写好了，所以我们只需要激活就行了
注意：
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");这一句话中,第一个参数是要安装的apk的路径,第二个参数是apk所对应的类型。可以砸tomcat的安装目录下的conf目录下的web.xml中找到
程序运行截图：
代码实现如下：
1、main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="安装" android:onClick="install" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="卸载" android:onClick="uninstall" /> </LinearLayout>
2、MainActivity
package com.njupt.install;import java.io.File;import android.net.Uri;import android.os.Bundle;import android.os.Environment;import android.app.Activity;import android.content.Intent;import android.view.Menu;import android.view.View;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);}public void install(View v){Intent intent = new Intent();intent.setAction(Intent.ACTION_VIEW);File file = new File(Environment.getExternalStorageDirectory(),"HtmlUI1.apk");intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");startActivity(intent);}public void uninstall(View v){Intent intent = new Intent(); intent.setAction(Intent.ACTION_DELETE); intent.setData(Uri.parse("package:com.njupt.htmlui1"));startActivity(intent);}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}
