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

复制代码代码如下:

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)

复制代码代码如下:

    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）

复制代码代码如下:

    package cn.ceadic.apkmgr; 

    import java.io.File; 
    import java.io.FileNotFoundException; 
    import java.io.FileOutputStream; 
    import java.io.IOException; 

    import android.content.Context;

        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); 

        } 
    }  

复制代码代码如下:

    package cn.ceadic.apkmgr;  

    import java.io.File;  
    import java.io.FileNotFoundException;

                if (pi != null) {

                }

            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()) {

            }

                return null;  
            }  

            File srcPackageFile = new File(filePath);

            PackageDeleteObserver observer = new PackageDeleteObserver();  
            mContext.getPackageManager().deletePackage(packageName, observer, 0);  

        }  
    }  

3、别忘记添加权限

复制代码代码如下:

    <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" />  

复制代码代码如下:

    <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
