前段时间做了一个批量安装卸载应用程序的小应用，由于安装卸载应用程序的部分API是隐藏的，所以必须在ubuntu下下载Android系统源码，并编译之后使用MM命令编译生成APK文件，其实也难。思路是这样的，在XX/packages/apps目录下有一个PackageInstaller的应用程序，Android机器中安装卸载都是由这个应用程序完成的。但是它没有批量安装和卸载的功能，如果要在自己的应用程序中添加批量安装和卸载的功能，其实很简单，只需要参考PakcageInstaller里面的安装卸载代码加个循环就可以了。但值得注意的是在编译的过程中必须复制PackageInstaller里面的Android.mk文件，修改文件为工程目录名。好了，废话不再多说，下面是关键代码

1、 Android.mk文件

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(call all-subdir-java-files)

LOCAL_PACKAGE_NAME := PackageInstaller

LOCAL_CERTIFICATE := platform

include $(BUILD_PACKAGE)

2、PakcageInstaller.java文件（关键代码）

package cn.ceadic.apkmgr;

import java.io.File;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import android.content.Context;

import android.content.Intent;

import android.content.pm.PackageInfo;

import android.content.pm.PackageManager;

import android.content.pm.PackageManager.NameNotFoundException;

import android.net.Uri;

import android.util.Log;

import android.content.pm.IPackageInstallObserver;

import android.content.pm.IPackageDeleteObserver;

import android.os.FileUtils;

public class PackageInstaller {

private File mTmpFile;

private final String TMP_FILE_NAME = "tmpCopy.apk";

private final static String TAG = "PackInstaller";

private Context mContext;

public PackageInstaller(Context context) {

mContext = context;

}

public void install(String path,String packageName){

Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.fromFile(new File(path)),

"application/vnd.android.package-archive");

mContext.startActivity(intent);

}

public void instatllBatch(String path, String packageName) {

Log.i(TAG, "path=" + path);

int installFlags = 0;

PackageManager pm = mContext.getPackageManager();

try {

PackageInfo pi = pm.getPackageInfo(packageName,

PackageManager.GET_UNINSTALLED_PACKAGES);

if (pi != null) {

installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;

}

} catch (NameNotFoundException e) {

}

if ((installFlags & PackageManager.INSTALL_REPLACE_EXISTING) != 0) {

Log.w(TAG, "Replacing package:" + packageName);

}

// Create temp file before invoking install api

mTmpFile = createTempPackageFile(path);

if (mTmpFile == null) {

// Message msg = mHandler.obtainMessage(INSTALL_COMPLETE);

// msg.arg1 = PackageManager.INSTALL_FAILED_INSUFFICIENT_STORAGE;

// mHandler.sendMessage(msg);

return;

}

Uri mPackageURI = Uri.parse("file://" + mTmpFile.getPath());

String installerPackageName = mContext.getIntent().getStringExtra(

Intent.EXTRA_INSTALLER_PACKAGE_NAME);

PackageInstallObserver observer = new PackageInstallObserver();

pm.installPackage(mPackageURI, observer, installFlags,

installerPackageName);

}

private File createTempPackageFile(String filePath) {

File tmpPackageFile = mContext.getFileStreamPath(TMP_FILE_NAME);

if (tmpPackageFile == null) {

Log.w(TAG, "Failed to create temp file");

return null;

}

if (tmpPackageFile.exists()) {

tmpPackageFile.delete();

}

// Open file to make it world readable

FileOutputStream fos;

try {

fos = openFileOutput(TMP_FILE_NAME, MODE_WORLD_READABLE);

} catch (FileNotFoundException e1) {

Log.e(TAG, "Error opening file " + TMP_FILE_NAME);

return null;

}

try {

fos.close();

} catch (IOException e) {

Log.e(TAG, "Error opening file " + TMP_FILE_NAME);

return null;

}

File srcPackageFile = new File(filePath);

if (!FileUtils.copyFile(srcPackageFile, tmpPackageFile)) {

Log.w(TAG, "Failed to make copy of file: " + srcPackageFile);

return null;

}

return tmpPackageFile;

}

private class PackageInstallObserver extends IPackageInstallObserver.Stub {

public void packageInstalled(String packageName, int returnCode) {

// Message msg = mHandler.obtainMessage(INSTALL_COMPLETE);

// msg.arg1 = returnCode;

// mHandler.sendMessage(msg);

Log.i(TAG, "====INSTALL_COMPLETE");

}

}

private class PackageDeleteObserver extends IPackageDeleteObserver.Stub {

public void packageDeleted(boolean succeeded) {

// Message msg = mHandler.obtainMessage(UNINSTALL_COMPLETE);

// msg.arg1 = succeeded?SUCCEEDED:FAILED;

// mHandler.sendMessage(msg);

Log.i(TAG, "====UNINSTALL_COMPLETE");

}

}

public void uninstall(String packageName){

Uri packageURI = Uri.parse("package:" + packageName);

Intent uninstallIntent = new Intent(Intent.ACTION_DELETE,

packageURI);

mContext.startActivity(uninstallIntent);

}

public void uninstallBatch(String packageName) {

PackageDeleteObserver observer = new PackageDeleteObserver();

mContext.getPackageManager().deletePackage(packageName, observer, 0);

}

}

3、别忘记添加权限

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.INSTALL_PACKAGES" />

<uses-permission android:name="android.permission.DELETE_PACKAGES" />

<uses-permission android:name="android.permission.CLEAR_APP_CACHE" />

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />

以上代码在Android2.1的SDK中编译通过，并正确批量安装卸载应用程序
