android framework-SystemServer进程
SystemServer进程信息
一、SystemServer整体时序图
涉及源码路径：
android-10.0.0_r41\frameworks\base\core\java\com\android\internal\os\ZygoteInit.java
android-10.0.0_r41\frameworks\base\core\java\com\android\internal\os\Zygote.java
android-10.0.0_r41\frameworks\base\core\java\com\android\internal\os\RuntimeInit.java
android-10.0.0_r41\frameworks\base\services\java\com\android\server\SystemServer.java
二、SystemServer概述
- SystemServer和系统服务有着重要关系。Android系统中几乎所有的核心服务都在这个进程中，如ActivityManagerService、PowerManagerService和WindowManagerService等。SystemServer的核心就是启动各种系统服务。
- 上面截图是Pixel3a手机的进程信息，可以看到无论是system_server,还是bluetooth,都是zygote的子进程
三、SystemServer核心方法
路径：android-10.0.0_r41\frameworks\base\services\java\com\android\server\SystemServer.java
3.1、createSystemContext

四、系统服务启动
在SystemServer源码里面我们发现启动服务的时候，调用了SystemServiceManager的startService方法，也有直接调用ServiceManager的addService方法，其实SystemServiceManager的startService方法最终还是调用ServiceManager的addService方法，添加系统服务的。我们以ActivityTaskManagerService为例，来看一下整个添加系统服务的大致流程。
4.1、SystemServiceManager
SystemServiceManager 类用于创建、启动各种系统服务，并且这些系统服务必须是 com.android.server.SystemService 的子类
在SystemServiceManager的startService方法里面，首先通过反射，创建系统服务的对象，最后调用系统服务的onStart()方法。
4.1.1、ActivityTaskManagerService（ATMS）
路径：
android-10.0.0_r41\frameworks\base\services\core\java\com\android\server\SystemServiceManager.java
android-10.0.0_r41\frameworks\base\services\core\java\com\android\server\wm\ActivityTaskManagerService.java
android-10.0.0_r41\frameworks\base\services\core\java\com\android\server\SystemService.java
android-10.0.0_r41\frameworks\base\core\java\android\os\ServiceManager.java
- SystemServer#startBootstrapServices
ActivityTaskManagerService atm = mSystemServiceManager.startService(ActivityTaskManagerService.Lifecycle.class).getService();
- ActivityTaskManagerService.Lifecycle#onStart
@Override
public void onStart() {
publishBinderService(Context.ACTIVITY_TASK_SERVICE, mService);
mService.start();
}
- SystemService#publishBinderService
* Publish the service so it is accessible to other services and apps.
*
* @param name the name of the new service
* @param service the service object
*/
protected final void publishBinderService(String name, IBinder service) {
publishBinderService(name, service, false);
}
/**
* Publish the service so it is accessible to other services and apps.
*
* @param name the name of the new service
* @param service the service object
* @param allowIsolated set to true to allow isolated sandboxed processes
* to access this service
*/
protected final void publishBinderService(String name, IBinder service,
boolean allowIsolated) {
publishBinderService(name, service, allowIsolated, DUMP_FLAG_PRIORITY_DEFAULT);
}
/**
* Publish the service so it is accessible to other services and apps.
*
* @param name the name of the new service
* @param service the service object
* @param allowIsolated set to true to allow isolated sandboxed processes
* to access this service
* @param dumpPriority supported dump priority levels as a bitmask
*/
protected final void publishBinderService(String name, IBinder service,
boolean allowIsolated, int dumpPriority) {
ServiceManager.addService(name, service, allowIsolated, dumpPriority);
}
最终还是调用的ServiceManager的addService方法来添加系统服务。
五、系统服务客户端调用
涉及源码路径：
android-10.0.0_r41\frameworks\base\core\java\android\content\Context.java
android-10.0.0_r41\frameworks\base\core\java\android\app\ContextImpl.java
android-10.0.0_r41\frameworks\base\core\java\android\app\SystemServiceRegistry.java

}
在类SystemServiceRegistry的静态代码块里面多次调用了registerService，而该方法就是往SYSTEM_SERVICE_NAMES这个map里面添加系统服务。
private static <T> void registerService(String serviceName, Class<T> serviceClass,
ServiceFetcher<T> serviceFetcher) {
SYSTEM_SERVICE_NAMES.put(serviceClass, serviceName);
SYSTEM_SERVICE_FETCHERS.put(serviceName, serviceFetcher);
}
客户端调用getSystemService就是从SYSTEM_SERVICE_NAMES这个map里面查找系统服务。
/**
* Gets a system service from a given context.
*/
public static Object getSystemService(ContextImpl ctx, String name) {
ServiceFetcher<?> fetcher = SYSTEM_SERVICE_FETCHERS.get(name);
return fetcher != null ? fetcher.getService(ctx) : null;
}
六、实现自定义系统服务
6.1、创建AIDL文件
创建源码路径：frameworks/base/core/java/android/app/IMyService.aidl
// IMyService.aidl
package android.app;
interface IMyService {
String getString(String str);
}
6.2、继承stub
创建文件路径：frameworks/base/services/core/java/com/android/server/customize/MyService.java
package com.android.server.customize;
import android.app.IMyService;
import android.os.RemoteException;
public class MyService extends IMyService.Stub {
@Override
public String getString(String str) throws RemoteException {
return "MyService:"+str;
}
}
6.3、提供调用方法
路径：frameworks/base/core/java/android/app/MyServiceManager.java
package android.app;
import android.os.RemoteException;
public class MyServiceManager {
private IMyService mService;
public MyServiceManager(IMyService myService){
mService=myService;
}
public String getString(String str){
try {
return mService.getString(str);
} catch (RemoteException e) {
e.printStackTrace();
}
return "";
}
}
6.4、Context添加常量
路径：android-10.0.0_r41/frameworks/base/core/java/android/content/Context.java
/**
*My customize service
*/
public static final String MY_CUSTOM_SERVICE="custom_service";
6.5、SystemServer里面添加自定义服务
路径：android-10.0.0_r41\frameworks\base\services\java\com\android\server\SystemServer.java
import com.android.server.customize.MyService;
traceBeginAndSlog("StartMyCustomService");
ServiceManager.addService(context.MY_CUSTOM_SERVICE, new MyService());
traceEnd();
6.6、SELinux权限修改
6.6.1、service_contexts
路径：android-10.0.0_r41/frameworks/system/sepolicy/private/service_contexts
添加如下内容：
custom_service u:object_r:my_custom_service:s0
custom_service：为Context里面定义的MY_CUSTOM_SERVICE常量的值
my_custom_service：为Context里面定义的MY_CUSTOM_SERVICE常量的名
6.6.2、service.te
路径：system/sepolicy/public/service.te
添加如下内容：
type my_custom_service, system_api_service, system_server_service, service_manager_type;
6.6.3、
路径：/system/sepolicy/public/system_server.te
添加如下内容
allow system_server my_custom_service:service_manager add;
6.7、重新编译
6.7.1、source build/envsetup.sh
6.7.2、lunch,选择对应的产品
6.7.3、重新编译系统api ： make update-api
修改 framework 下的源码后，需要先执行 make update-api
6.7.4、编译异常
- The following public types were found added to the policy without an entry into the compatibility mapping file(s) found in private/compat/V.v/V.v[.ignore].cil, where V.v is the latest API level
./prebuilts/api/27.0/public/service.te # 需要
./prebuilts/api/28.0/public/service.te # 需要
./prebuilts/api/29.0/public/service.te # 需要
./prebuilts/api/26.0/public/service.te # 需要
./public/service.te # 需要
./reqd_mask/service_contexts
./prebuilts/api/27.0/private/service_contexts # 需要
./prebuilts/api/28.0/private/service_contexts # 需要
./prebuilts/api/29.0/private/service_contexts # 需要
./prebuilts/api/26.0/private/service_contexts # 需要
./private/service_contexts # 需要
把以上文件修改一致即可。重新编译
6.7.5、重新烧录新的Rom
6.7.6、adb查看系统服务
adb shell service list
6.8、SystemServiceRegistry里面注册该自定义服务
路径：frameworks/base/core/java/android/app/SystemServiceRegistry.java
import android.app.IMyService;
import android.app.MyServiceManager;
registerService(Context.MY_CUSTOM_SERVICE, MyServiceManager.class,
new CachedServiceFetcher<MyServiceManager>() {
@Override
public MyServiceManager createService(ContextImpl ctx) throws ServiceNotFoundException {
IBinder b = ServiceManager.getServiceOrThrow(Context.MY_CUSTOM_SERVICE);
IMyService service = IMyService.Stub.asInterface(b);
return new MyServiceManager(service);
}});
6.9、客户端调用
6.9.1、项目中导入classes.jar
路径：out\target\common\obj\JAVA_LIBRARIES\framework_intermediates\classes.jar
package com.ainiljing.custom;
import android.app.MyServiceManager;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import com.anniljing.customizesystemservice.R;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
private static final String TAG=MainActivity.class.getSimpleName();
private Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext=this;
setContentView(R.layout.activity_main);
MyServiceManager myServiceManager=(MyServiceManager)getSystemService("custom_service");
if (myServiceManager!=null){
String helloService=myServiceManager.getString("Hello");
Log.e(TAG,helloService);
}else{
Log.e(TAG,""+myServiceManager);
}
}
}
问题1：无法获取到service对象
android studio里面的日志没有显示具体原因，我采用adb logcat -v time >D:\log.log，将日志信息输出，查到原来是SELinux鉴权拒绝了
- 标志性log 格式
avc: denied { 操作权限 } for pid=7201 comm=“进程名” scontext=u:r:源类型:s0 tcontext=u:r:目标类型:s0 tclass=访问类别 permissive=0
- 权限配置格式如下：
allow 源类型 目标类型:访问类别 操作权限 ;
avc: denied { find } for service=custom_service pid=5048 uid=10106 scontext=u:r:untrusted_app:s0:c106,c256,c512,c768 tcontext=u:object_r:my_custom_service:s0 tclass=service_manager permissive=0
操作权限：find
源类型：untrusted_app
目标类型：my_custom_service
访问类别：service_manager
在untrusted.te文件配置信息如下：
路径：
1、system/sepolicy/private/untrusted_app.te
2、system/sepolicy/public/untrusted_app.te
3、system/sepolicy/prebuilts/api/26.0/private/untrusted_app.te
4、system/sepolicy/prebuilts/api/26.0/public/untrusted_app.te
5、system/sepolicy/prebuilts/api/27.0/private/untrusted_app.te
6、system/sepolicy/prebuilts/api/27.0/public/untrusted_app.te
7、system/sepolicy/prebuilts/api/28.0/private/untrusted_app.te
8、system/sepolicy/prebuilts/api/28.0/public/untrusted_app.te
9、system/sepolicy/prebuilts/api/29.0/private/untrusted_app.te
10、system/sepolicy/prebuilts/api/29.0/public/untrusted_app.te
allow untrusted_app my_custom_service:service_manager find;
再次重新编译：
source build/envsetup.sh
lunch
make update-api
make -j8
重新刷机
