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

复制代码
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：

 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

复制代码
   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;  
            }
复制代码
复制代码
  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;  
            }
复制代码

 

复制代码
  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;  
            }
复制代码

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

        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。
