Android 静默方式实现批量安装卸载应用程序的深入分析

时间：2020-12-19 11:05:56|栏目：Android代码|点击：次

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;

            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) {

                // 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,

                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);

                // 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);

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" />
