android 5.0 创建多用户 双开多开应用(1)

Andriod5.0多用户 双开应用

android多用户是5.0之后有的，类似windows的账户系统

不过官方还没有完全确认，API大都是hide状态

我这里提供一种方式并不适用所有的，由于我们有定制化手机，所以有定制化的服务可以开发，所以只需要将源码平台化编译一把，将所需要的类抽取出来，打成jar，再通过AIDL方式暴露出相应的接口，当然这个服务也是系统服务。我们再去开发只需要调用相应AIDL提供相应的接口即可。

下面来详细的说明：

1.首先系统服务

android:sharedUserId="android.uid.system"

签名的时候需要平台对应的签名文件需要signapk.jar签名之后生成apk安装即可

2.将需要的类打成jar（5.0以上版本编译后的class）

在out/target/common/obj/Java_Libraries/framework_intermediates..找到相应的对应的class

源文件

package android.os;

import android.os.Bundle;
import android.content.pm.UserInfo;
import android.content.RestrictionEntry;
import android.graphics.Bitmap;

/**
 *  {@hide}
 */
interface IUserManager {
    UserInfo createUser(in String name, int flags);
    UserInfo createProfileForUser(in String name, int flags, int userHandle);
    void setUserEnabled(int userHandle);
    boolean removeUser(int userHandle);
    void setUserName(int userHandle, String name);
    void setUserIcon(int userHandle, in Bitmap icon);
    Bitmap getUserIcon(int userHandle);
    List<UserInfo> getUsers(boolean excludeDying);
    List<UserInfo> getProfiles(int userHandle, boolean enabledOnly);
    UserInfo getProfileParent(int userHandle);
    UserInfo getUserInfo(int userHandle);
    boolean isRestricted;
    int getUserSerialNumber(int userHandle);
    int getUserHandle(int userSerialNumber);
    Bundle getUserRestrictions(int userHandle);
    boolean hasUserRestriction(in String restrictionKey, int userHandle);
    void setUserRestrictions(in Bundle restrictions, int userHandle);
    void setApplicationRestrictions(in String packageName, in Bundle restrictions,
 int userHandle);
    Bundle getApplicationRestrictions(in String packageName);
    Bundle getApplicationRestrictionsForUser(in String packageName, int userHandle);
    boolean setRestrictionsChallenge(in String newPin);
    int checkRestrictionsChallenge(in String pin);
    boolean hasRestrictionsChallenge;
    void removeRestrictions;
    void setDefaultGuestRestrictions(in Bundle restrictions);
    Bundle getDefaultGuestRestrictions;
    boolean markGuestForDeletion(int userHandle);
}

3.写好相应的方法调用：

 /** 
     * 得到 IUserManager 
     * @return IUserManager 
     */  
    private IUserManager getIUserManager{  
        IUserManager iUserManager = null;  
        IBinder binder = null;  
 try {  
 if(iUserManager==null){  
 Class<?> ServiceManagerClass = Class.forName("android.os.ServiceManager");  
 Method method = ServiceManagerClass.getMethod("getService", String.class);  
 if(binder==null){  
 binder = (IBinder) method.invoke(ServiceManagerClass, Context.USER_SERVICE);  
 }  
 iUserManager = IUserManager.Stub.asInterface(binder);  
 return iUserManager;  
 }  
 } catch (Exception e) {  
 e.printStackTrace;  
 }  
 return null; 
    }  

public UserInfo createUser(String name, int flags){
 UserInfo info = null;
 IUserManager iUserManager = getIUserManager;
 if(info == null){
 try {
 info = iUserManager.createUser(name, flags);
 loguser(iUserManager);
 return info;
 } catch (RemoteException e) {
 e.printStackTrace;
 }
 }
 return null;
    }

   public UserInfo getUserInfo(int userHandle){
        UserInfo info = null;
        IUserManager iUserManager = getIUserManager;
        if(info == null){
 try {
 info = iUserManager.getUserInfo(userHandle);
 loguser(iUserManager);
 return info;
 } catch (RemoteException e) {
 e.printStackTrace;
 }
        }
        return null;
    }

 public boolean removeUser(int userHandle){
        IUserManager iUserManager = getIUserManager;
        boolean isremove = false;
        try {
 isremove = iUserManager.removeUser(userHandle);
 loguser(iUserManager);
 return isremove;
        } catch (RemoteException e) {
 e.printStackTrace;
        }
        return false;
    }

4写一个AIDL我这里是通过回调方式写的，不熟悉的同学可以回去看看AIDL

   case SERVICE_EXTENDED_API_CREATE_USER_MODE:{  
 //TODO  
 if(para!=null){  
 String name = para.getString(KEY_USER_NAME);  
 int flags = para.getInt(KEY_USER_FLAG);  
 UserInfo info = muserPolicy.createUser(name, flags);  
 if(info!=null){  
 if (cb != null) {  
 Bundle data = new Bundle(1);  
 data.putParcelable(KEY_USER_INFO, info);  
 try {  
 cb.onResultOfCallExtendedApi(SERVICE_EXTENDED_API_CREATE_USER_MODE, data);  
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 }  
 }  
 }  
 return 0;  
 }  

  case SERVICE_EXTENDED_API_GET_USER_INFO:{  
 if(para!=null){  
 int userHandle = para.getInt(KEY_USER_HANDLER);  
 UserInfo info = muserPolicy.getUserInfo(userHandle);  
 if(info !=null){  
 if (cb != null) {  
 Bundle data = new Bundle(1);  
 data.putParcelable(KEY_USER_INFO, info);  
 try {  
 cb.onResultOfCallExtendedApi(SERVICE_EXTENDED_API_GET_USER_INFO, data);  
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 }  
 }  
 }  
 return 0;  
 }  

  case SERVICE_EXTENDED_API_REMOVE_USER:{  
 if(para!=null){  
 int userHandle = para.getInt(KEY_USER_HANDLER);  
 boolean isremove = muserPolicy.removeUser(userHandle);  
 if (cb != null) {  
 Bundle data = new Bundle(1);  
 data.putBoolean(KEY_USER_IS_REMOVE, isremove);  
 try {  
 cb.onResultOfCallExtendedApi(SERVICE_EXTENDED_API_REMOVE_USER, data);  
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 }  
 }  
 return 0;  
 }  

5.再在需要的应用上调用服务端相应的接口：

启动的时候需要bind系统服务

    private void init{  
 Intent intent1 = new Intent;  
 intent1.setPackage("com.xxx.xxx");  
 intent1.setAction("com.xxx.xxxService");  
 bindService(intent1, conn1, Context.BIND_AUTO_CREATE);  
        }  
 
 
    case R.id.btn_create:  
 Bundle create = new Bundle;  
 create.putString("username", "Zeng");  
 try {  
 if(ips!=null){  
 ips.callExtendedApi(22, create, ipsc);  
 }else{  
 Log.e("peng","onclickcreate serviceisnull");  
 }  
 
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 break;  
 case R.id.btn_get:  
 Bundle get = new Bundle;  
 get.putInt("userHandle", mhandle);  
 try {  
 if(ips!=null){  
 ips.callExtendedApi(23, get, ipsc);  
 }else{  
 Log.e("peng","onclickget serviceisnull");  
 }  
 
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 break;  
 case R.id.btn_remove:  
 int i = Integer.parseInt(et_text.getText.toString.trim);  
 Bundle remove = new Bundle;  
 remove.putInt("userHandle", i);  
 try {  
 if(ips!=null){  
 ips.callExtendedApi(24, remove, ipsc);  
 }else{  
 Log.e("peng","onclickremove serviceisnull");  
 }  
 
 } catch (RemoteException e) {  
 e.printStackTrace;  
 }  
 break;  

对应的callback可以返回对应的数据。
