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
IuserMannager.aidl
packageandroid.os;
importandroid.os.Bundle;
importandroid.content.pm.UserInfo;
importandroid.content.RestrictionEntry;
importandroid.graphics.Bitmap;
/**
* {@hide}
*/
interfaceIUserManager {
UserInfocreateUser(in String name, int flags); //创建User
UserInfocreateProfileForUser(in String name, int flags, int userHandle);
voidsetUserEnabled(int userHandle);
booleanremoveUser(int userHandle); //移除User
voidsetUserName(int userHandle, String name);
voidsetUserIcon(int userHandle, in Bitmap icon);
BitmapgetUserIcon(int userHandle);
ListgetUsers(boolean excludeDying); //得到Users
ListgetProfiles(int userHandle, boolean enabledOnly);
UserInfogetProfileParent(int userHandle);
UserInfogetUserInfo(int userHandle);
booleanisRestricted();
intgetUserSerialNumber(int userHandle);
intgetUserHandle(int userSerialNumber);
BundlegetUserRestrictions(int userHandle);
booleanhasUserRestriction(in String restrictionKey, int userHandle);
voidsetUserRestrictions(in Bundle restrictions, int userHandle);
voidsetApplicationRestrictions(in String packageName, in Bundlerestrictions,
intuserHandle);
BundlegetApplicationRestrictions(in String packageName);
BundlegetApplicationRestrictionsForUser(in String packageName, intuserHandle);
booleansetRestrictionsChallenge(in String newPin);
intcheckRestrictionsChallenge(in String pin);
booleanhasRestrictionsChallenge();
voidremoveRestrictions();
voidsetDefaultGuestRestrictions(in Bundle restrictions);
BundlegetDefaultGuestRestrictions();
booleanmarkGuestForDeletion(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。
