Android静默方式实现批量安装卸载应用程序

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

[plain] view plain copy

LOCAL_PATH:=$(callmy-dir)
include$(CLEAR_VARS)
LOCAL_MODULE_TAGS:=optional
LOCAL_SRC_FILES:=$(callall-subdir-java-files)
LOCAL_PACKAGE_NAME:=PackageInstaller
LOCAL_CERTIFICATE:=platform
include$(BUILD_PACKAGE)

2、PakcageInstaller.java文件（关键代码）

[java] view plain copy

packagecn.ceadic.apkmgr;
importjava.io.File;
importjava.io.FileNotFoundException;
importjava.io.FileOutputStream;
importjava.io.IOException;
importandroid.content.Context;
importandroid.content.Intent;
importandroid.content.pm.PackageInfo;
importandroid.content.pm.PackageManager;
importandroid.content.pm.PackageManager.NameNotFoundException;
importandroid.net.Uri;
importandroid.util.Log;
importandroid.content.pm.IPackageInstallObserver;
importandroid.content.pm.IPackageDeleteObserver;
importandroid.os.FileUtils;
publicclassPackageInstaller{
privateFilemTmpFile;
privatefinalStringTMP_FILE_NAME="tmpCopy.apk";
privatefinalstaticStringTAG="PackInstaller";
privateContextmContext;
publicPackageInstaller(Contextcontext){
mContext=context;
}
publicvoidinstall(Stringpath,StringpackageName){
Intentintent=newIntent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(newFile(path)),
"application/vnd.android.package-archive");
mContext.startActivity(intent);
}
publicvoidinstatllBatch(Stringpath,StringpackageName){
Log.i(TAG,"path="+path);
intinstallFlags=0;
PackageManagerpm=mContext.getPackageManager();
try{
PackageInfopi=pm.getPackageInfo(packageName,
PackageManager.GET_UNINSTALLED_PACKAGES);
if(pi!=null){
installFlags|=PackageManager.INSTALL_REPLACE_EXISTING;
}
}catch(NameNotFoundExceptione){
}
if((installFlags&PackageManager.INSTALL_REPLACE_EXISTING)!=0){
Log.w(TAG,"Replacingpackage:"+packageName);
}
//Createtempfilebeforeinvokinginstallapi
mTmpFile=createTempPackageFile(path);
if(mTmpFile==null){
//Messagemsg=mHandler.obtainMessage(INSTALL_COMPLETE);
//msg.arg1=PackageManager.INSTALL_FAILED_INSUFFICIENT_STORAGE;
//mHandler.sendMessage(msg);
return;
}
UrimPackageURI=Uri.parse("file://"+mTmpFile.getPath());
StringinstallerPackageName=mContext.getIntent().getStringExtra(
Intent.EXTRA_INSTALLER_PACKAGE_NAME);
PackageInstallObserverobserver=newPackageInstallObserver();
pm.installPackage(mPackageURI,observer,installFlags,
installerPackageName);
}
privateFilecreateTempPackageFile(StringfilePath){
FiletmpPackageFile=mContext.getFileStreamPath(TMP_FILE_NAME);
if(tmpPackageFile==null){
Log.w(TAG,"Failedtocreatetempfile");
returnnull;
}
if(tmpPackageFile.exists()){
tmpPackageFile.delete();
}
//Openfiletomakeitworldreadable
FileOutputStreamfos;
try{
fos=openFileOutput(TMP_FILE_NAME,MODE_WORLD_READABLE);
}catch(FileNotFoundExceptione1){
Log.e(TAG,"Erroropeningfile"+TMP_FILE_NAME);
returnnull;
}
try{
fos.close();
}catch(IOExceptione){
Log.e(TAG,"Erroropeningfile"+TMP_FILE_NAME);
returnnull;
}
FilesrcPackageFile=newFile(filePath);
if(!FileUtils.copyFile(srcPackageFile,tmpPackageFile)){
Log.w(TAG,"Failedtomakecopyoffile:"+srcPackageFile);
returnnull;
}
returntmpPackageFile;
}
privateclassPackageInstallObserverextendsIPackageInstallObserver.Stub{
publicvoidpackageInstalled(StringpackageName,intreturnCode){
//Messagemsg=mHandler.obtainMessage(INSTALL_COMPLETE);
//msg.arg1=returnCode;
//mHandler.sendMessage(msg);
Log.i(TAG,"====INSTALL_COMPLETE");
}
}
privateclassPackageDeleteObserverextendsIPackageDeleteObserver.Stub{
publicvoidpackageDeleted(booleansucceeded){
//Messagemsg=mHandler.obtainMessage(UNINSTALL_COMPLETE);
//msg.arg1=succeeded?SUCCEEDED:FAILED;
//mHandler.sendMessage(msg);
Log.i(TAG,"====UNINSTALL_COMPLETE");
}
}
publicvoiduninstall(StringpackageName){
UripackageURI=Uri.parse("package:"+packageName);
IntentuninstallIntent=newIntent(Intent.ACTION_DELETE,
packageURI);
mContext.startActivity(uninstallIntent);
}
publicvoiduninstallBatch(StringpackageName){
PackageDeleteObserverobserver=newPackageDeleteObserver();
mContext.getPackageManager().deletePackage(packageName,observer,0);
}
}

3、别忘记添加权限

[html] view plain copy

<uses-permissionandroid:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permissionandroid:name="android.permission.INSTALL_PACKAGES"/>
<uses-permissionandroid:name="android.permission.DELETE_PACKAGES"/>
<uses-permissionandroid:name="android.permission.CLEAR_APP_CACHE"/>
<uses-permissionandroid:name="android.permission.READ_PHONE_STATE"/>
<uses-permissionandroid: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
