android 禁止第三方apk安装和卸载的方法详解

需求是这样的，客户要求提供系统的接口来控制apk的安装和卸载，接口如下

boolean setAppInstallationPolicies(int mode, String[] appPackageNames)mode：应用名单类型0：黑名单(应用包名列表中的所有项都不允许安装)；1：白名单(只允许安装应用包名列表中的项)。appPackageNames：应用包名列表。当appPackageNames为空时，取消所有已设定的应用。成功返回true；失败返回false。String[] getAppInstallationPolicies()返回值为当前应用安装管控状态string[0]：功能模式，参见setAppInstallationPolicies方法的mode参数。string[1]至string[n-1]：应用包名列表。 boolean setAppUninstallationPolicies(int mode, String[] appPackageNames)mode：应用名单类型0：黑名单(应用包名列表中的所有项均强制卸载)；1：白名单(应用包名列表中的所有项禁止卸载)。appPackageNames：应用包名列表。当appPackageNames为空时，取消所有已设定的应用。成功返回true；失败返回false。String[] getAppUninstallationPolicies()返回值为当前应用卸载管控状态string[0]：功能模式，参见setAppUninstallationPolicies方法的mode参数。string[1]至string[n-1]：应用包名列表。

android版本为9.0，首先想到的是在系统里面添加一个自己的service,分别在frameworks/base/core/java/android/app/添加IPolicyManager.aidl，frameworks/base/services/core/java/com/android/server/添加PolicyManagerService.java，在frameworks/base/添加policy/java/ga/mdm/PolicyManager.java，内容如下

package android.app; /** {@hide} */interface IPolicyManager{boolean setAppInstallationPolicies(int mode,inout String[] appPackageNames);String[] getAppInstallationPolicies();boolean setAppUninstallationPolicies(int mode,inout String[] appPackageNames);String[] getAppUninstallationPolicies();}

package com.android.server; import android.content.Context;import android.content.Intent;import android.content.IntentFilter; import android.os.ServiceManager;import android.os.SystemProperties;import android.provider.Settings;import android.util.Slog; import java.lang.reflect.Field;import java.util.ArrayList; import android.app.IPolicyManager;import android.net.wifi.WifiManager;import android.content.pm.PackageManager;import android.app.ActivityManager;import android.content.pm.IPackageDataObserver; public class PolicyManagerService extends IPolicyManager.Stub {private final String TAG = 'PolicyManagerService';private Context mContext;private String[] mAppPackageNames = null;private String[] mAppUninstallPackageNames = null; public PolicyManagerService(Context context) { mContext = context; }@Overridepublic boolean setAppInstallationPolicies(int mode, String[] appPackageNames){if(mode==0){Settings.System.putInt(mContext.getContentResolver(),'customer_app_status', 0);}else if(mode==1){Settings.System.putInt(mContext.getContentResolver(),'customer_app_status', 1);}else{return false;}mAppPackageNames = appPackageNames;return true;}@Overridepublic String[] getAppInstallationPolicies(){return mAppPackageNames;}@Overridepublic boolean setAppUninstallationPolicies(int mode,String[] appPackageNames){if(mode==0){Settings.System.putInt(mContext.getContentResolver(),'customer_appuninstall_status', 0);}else if(mode==1){Settings.System.putInt(mContext.getContentResolver(),'customer_appuninstall_status', 1);}else{return false;}mAppUninstallPackageNames = appPackageNames;return true;}@Overridepublic String[] getAppUninstallationPolicies(){return mAppUninstallPackageNames;}}

package ga.mdm; import android.util.Slog;import android.os.RemoteException;import android.content.Context;import android.app.IPolicyManager; public class PolicyManager {private final String TAG = 'PolicyManager';Context mContext; private final IPolicyManager mService; public PolicyManager(Context context,IPolicyManager mService) {mContext = context; this.mService = mService; } public boolean setAppInstallationPolicies(int mode,String[] appPackageNames){try { return mService.setAppInstallationPolicies(mode,appPackageNames); } catch (RemoteException ex) { ex.printStackTrace();return false; } }public String[] getAppInstallationPolicies(){try { return mService.getAppInstallationPolicies(); } catch (RemoteException ex) { ex.printStackTrace();return null; } }public boolean setAppUninstallationPolicies(int mode,String[] appPackageNames){try { return mService.setAppUninstallationPolicies(mode,appPackageNames); } catch (RemoteException ex) { ex.printStackTrace();return false; } }public String[] getAppUninstallationPolicies(){try { return mService.getAppUninstallationPolicies(); } catch (RemoteException ex) { ex.printStackTrace();return null; } }}

同时在frameworks/base/policy/添加Android.mk

这里为什么将PolicyManager.java单独出来，因为PolicyManager.java是提供给客户用的，单独生成一个jar包，客户只需要使用policy.jar就可以调用，同时需要添加

这样就行了，烧录重新开机使用adb shell service list可以看到添加的service

policy: [android.app.IPolicyManager]

在outtargetcommonobjJAVA_LIBRARIESpolicy_intermediates找到classes.jar，这就是提供给客户用的jar

具体的禁止和卸载方法如下：

禁止安装可以修改PackageManagerService.java，在handleStartCopy方法中添加下面的代码

public void handleStartCopy() throws RemoteException { int ret = PackageManager.INSTALL_SUCCEEDED; // If we’re already staged, we’ve firmly committed to an install location if (origin.staged) {if (origin.file != null) { installFlags |= PackageManager.INSTALL_INTERNAL; installFlags &= ~PackageManager.INSTALL_EXTERNAL;} else { throw new IllegalStateException('Invalid stage location');} } final boolean onSd = (installFlags & PackageManager.INSTALL_EXTERNAL) != 0; final boolean onInt = (installFlags & PackageManager.INSTALL_INTERNAL) != 0; final boolean ephemeral = (installFlags & PackageManager.INSTALL_INSTANT_APP) != 0; PackageInfoLite pkgLite = null; if (onInt && onSd) {// Check if both bits are set.Slog.w(TAG, 'Conflicting flags specified for installing on both internal and external');ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION; } else if (onSd && ephemeral) {Slog.w(TAG, 'Conflicting flags specified for installing ephemeral on external');ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION; } else {pkgLite = mContainerService.getMinimalPackageInfo(origin.resolvedPath, installFlags, packageAbiOverride);//add by juemePolicyManager policyManager = (PolicyManager)mContext.getSystemService('policy');String[] appNames = policyManager.getAppInstallationPolicies();if(appNames!=null && appNames.length>0){int app_status = android.provider.Settings.System.getInt(mContext.getContentResolver(),'customer_app_status', -1);Slog.w(TAG,'app_status '+app_status);if(app_status==0){for (int i = 0; i < appNames.length; i++) {Slog.w(TAG,'appNames 0 '+appNames[i]);if (pkgLite.packageName.equals(appNames[i])){ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;break;}}}else if(app_status==1){for (int i = 0; i < appNames.length; i++) {Slog.w(TAG,'appNames 1 '+appNames[i]);if (pkgLite.packageName.equals(appNames[i])){ret = PackageManager.INSTALL_SUCCEEDED;break;}else{ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;}}}}//add end

这样在安装时候就会报安装位置不对的信息。

接着是禁止卸载，在PackageInstallerService.java的uninstall添加下面的方法。

@Override public void uninstall(VersionedPackage versionedPackage, String callerPackageName, int flags,IntentSender statusReceiver, int userId) throws RemoteException {//add by juemePolicyManager policyManager = (PolicyManager)mContext.getSystemService('policy');String[] appNames = policyManager.getAppUninstallationPolicies();if(appNames!=null && appNames.length>0){int appuninstall_status = android.provider.Settings.System.getInt(mContext.getContentResolver(),'customer_appuninstall_status', -1);Slog.w(TAG,'appuninstall_status '+appuninstall_status+' mInstallerPackageName '+versionedPackage.getPackageName());boolean isUninstall = true;//默认都是可卸载if(appuninstall_status==0){for (int i = 0; i < appNames.length; i++) {if (versionedPackage.getPackageName().equals(appNames[i])){isUninstall = true;break;}else{isUninstall = false;}}if(!isUninstall){return;}}else if(appuninstall_status==1){//应用包名列表中的所有项禁止卸载for (int i = 0; i < appNames.length; i++) {if (versionedPackage.getPackageName().equals(appNames[i])){isUninstall = false;break;}else{isUninstall = true;}}if(!isUninstall){return;}}}//add end
