Android 静默方式实现批量安装卸载应用程序的深入分析

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;
    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

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:

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
