注意：
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");這一句話(huà)中,第一個(gè)參數(shù)是要安裝的apk的路徑,第二個(gè)參數(shù)是apk所對(duì)應(yīng)的類(lèi)型。可以砸tomcat的安裝目錄下的conf目錄下的web.xml中找到
程序運(yùn)行截圖：
代碼實(shí)現(xiàn)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="安裝"
android:onClick="install"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="卸載"
android:onClick="uninstall"

</LinearLayout>
2、MainActivity

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.setAction(Intent.ACTION_DELETE);
intent.setData(Uri.parse("package:com.njupt.htmlui1"));
startActivity(intent);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {

getMenuInflater().inflate(R.menu.main, menu);
return true;
