一 System Server

     上篇分析了Zygote创建SystemServer的流程,本篇则分析SystemServer的实际工作内容。

1.0 main

public static void main(String[] args) {
    new SystemServer().run(); // 先new一个SystemServer对象,然后调用它的run()方法
}

Java中start方法与run方法的区别:
调用start方法会创建一个新线程,并且run方法中的代码在新的线程上运行。
调用run方法的不会创建新线程,run方法中的代码继续在当前线程上运行。

1.1 run

private void run() {
    try {
        Trace.traceBegin(Trace.TRACE_TAG_SYSTEM_SERVER, “InitBeforeStartServices”); // 启动Systrace追踪InitBeforeStartServices
        // If a device’s clock is before 1970 (before 0), a lot of
        // APIs crash dealing with negative numbers, notably
        // java.io.File#setLastModified, so instead we fake it and
        // hope that time from cell towers or NTP fixes it shortly.
        if (System.currentTimeMillis() < EARLIEST_SUPPORTED_TIME) { // 类UNIX系统时间最早从1970开始计算
            Slog.w(TAG, “System clock is before 1970; setting to 1970.”);
            SystemClock.setCurrentTimeMillis(EARLIEST_SUPPORTED_TIME);
        }



        // If the system has “persist.sys.language” and friends set, replace them with
        // “persist.sys.locale”. Note that the default locale at this point is calculated
        // using the “-Duser.locale” command line flag. That flag is usually populated by
        // AndroidRuntime using the same set of system properties, but only the system_server
        // and system apps are allowed to set them.
        //
        // NOTE: Most changes made here will need an equivalent change to
        // core/jni/AndroidRuntime.cpp
        if (!SystemProperties.get(“persist.sys.language”).isEmpty()) {
            final String languageTag = Locale.getDefault().toLanguageTag(); // 本地化



            SystemProperties.set(“persist.sys.locale”, languageTag); // persist.sys.locale=zh-CN



            SystemProperties.set(“persist.sys.language”, “”);
            SystemProperties.set(“persist.sys.country”, “”);
            SystemProperties.set(“persist.sys.localevar”, “”);
        }



        // Here we go!
        Slog.i(TAG, “Entered the Android system server!”);
        EventLog.writeEvent(EventLogTags.BOOT_PROGRESS_SYSTEM_RUN, SystemClock.uptimeMillis()); // Android时间日志



        // In case the runtime switched since last boot (such as when
        // the old runtime was removed in an OTA), set the system
        // property so that it is in sync. We can’t do this in
        // libnativehelper’s JniInvocation::Init code where we already
        // had to fallback to a different runtime because it is
        // running as root and we need to be the system user to set
        // the property. http://b/11463182
        SystemProperties.set(“persist.sys.dalvik.vm.lib.2”, VMRuntime.getRuntime().vmLibrary()); // 虚拟机库文件 // VMRuntime_vmLibrary返回libart.so



        // Enable the sampling profiler.
        if (SamplingProfilerIntegration.isEnabled()) {
            SamplingProfilerIntegration.start(); // 启动SamplingProfilerIntegration进行性能统计
            mProfilerSnapshotTimer = new Timer();
            mProfilerSnapshotTimer.schedule(new TimerTask() {
                    @Override
                    public void run() {
                        SamplingProfilerIntegration.writeSnapshot(“system_server”, null);
                    }
                }, SNAPSHOT_INTERVAL, SNAPSHOT_INTERVAL); // 每隔1小时调用一次,将结果保存到/data/snapshots/system_server
        }



        // Mmmmmm… more memory!
        VMRuntime.getRuntime().clearGrowthLimit();   // 清除虚拟机运行时内存增长上限



        // The system server has to run all of the time, so it needs to be
        // as efficient as possible with its memory usage.
        VMRuntime.getRuntime().setTargetHeapUtilization(0.8f); // 设置虚拟机运行时的内存堆的利用率为0.8



        // Some devices rely on runtime fingerprint generation, so make sure
        // we’ve defined it before booting further.
        Build.ensureFingerprintProperty(); // 设置ro.build.fingerprint属性值



        // Within the system server, it is an error to access Environment paths without
        // explicitly specifying a user.
        Environment.setUserRequired(true); // 设置必须指定用户后才可以访问环境变量



        // Ensure binder calls into the system always run at foreground priority.
        BinderInternal.disableBackgroundScheduling(true); // 确保binder系统调用,总是运行在前台优先级



        // Prepare the main looper thread (this thread).
        android.os.Process.setThreadPriority(
            android.os.Process.THREAD_PRIORITY_FOREGROUND); // 设置system_server进程的优先级为前台优先级
        android.os.Process.setCanSelfBackground(false); // 禁止system_server自行将自己设为后台进程
        Looper.prepareMainLooper(); // 创建主线程Looper



        // Initialize native services.
        System.loadLibrary(“android_servers”); //加载android_servers.so动态库



        // Check whether we failed to shut down last time we tried.
        // This call may not return.
        performPendingShutdown(); // 获取sys.shutdown.requested属性,判断是否需要关机或重启,如果是的话则执行相应操作



        // Initialize the system context.
        createSystemContext(); // 初始化系统上下文



        // Create the system service manager.
        mSystemServiceManager = new SystemServiceManager(mSystemContext); // 创建系统服务管理对象
        LocalServices.addService(SystemServiceManager.class, mSystemServiceManager); // //将mSystemServiceManager添加到本地服务的ArrayMap中
    } finally {
        Trace.traceEnd(Trace.TRACE_TAG_SYSTEM_SERVER); // 停止Systrace追踪InitBeforeStartServices
    }



    // Start services.
    try {
        Trace.traceBegin(Trace.TRACE_TAG_SYSTEM_SERVER, “StartServices”); // 启动Systrace追踪StartServices
        startBootstrapServices(); // 启动引导服务
        startCoreServices(); // 启动核心服务

        throw ex;
    } finally {
        Trace.traceEnd(Trace.TRACE_TAG_SYSTEM_SERVER); // 停止Systrace追踪StartServices
    }



    // For debug builds, log event loop stalls to dropbox for analysis.
    if (StrictMode.conditionallyEnableDebugLogging()) { // 严格模式,用于调试
        Slog.i(TAG, “Enabled StrictMode for system server main thread.”);
    }



    // Loop forever.
    Looper.loop(); // 一直循环,获取并处理消息
    throw new RuntimeException(“Main thread loop unexpectedly exited”);
}




1.3 createSystemContext

private void createSystemContext() {
    ActivityThread activityThread = ActivityThread.systemMain(); // 创建ActivityThread对象
    mSystemContext = activityThread.getSystemContext(); // 创建并获取ContextImpl
    mSystemContext.setTheme(android.R.style.Theme_DeviceDefault_Light_DarkActionBar); // 设置系统主题
}


1.4 startBootstrapServices

private void startBootstrapServices() {
    // Wait for installd to finish starting up so that it has a chance to
    // create critical directories such as /data/user with the appropriate
    // permissions.  We need this to complete before we initialize other services.
    Installer installer = mSystemServiceManager.startService(Installer.class); // 启动Installer系统服务,并等待和installd建立socket连接

    // Activity manager runs the show.
    mActivityManagerService = mSystemServiceManager.startService(

    mActivityManagerService.setSystemServiceManager(mSystemServiceManager); // 设置ActivityManagerService的SystemServiceManager
    mActivityManagerService.setInstaller(installer); // 设置ActivityManagerService的Installer

    // Power manager needs to be started early because other services need it.
    // Native daemons may be watching for it to be registered so it must be ready
    // to handle incoming binder calls immediately (including being able to verify
    // the permissions for those calls).
    mPowerManagerService = mSystemServiceManager.startService(PowerManagerService.class); // 启动PowerManagerService系统服务

    // Now that the power manager has been started, let the activity manager
    // initialize power management features.
    Trace.traceBegin(Trace.TRACE_TAG_SYSTEM_SERVER, “InitPowerManagement”);
    mActivityManagerService.initPowerManagement(); // 初始化PowerManagement
    Trace.traceEnd(Trace.TRACE_TAG_SYSTEM_SERVER);

    // Manages LEDs and display backlight so we need it to bring up the display.
    mSystemServiceManager.startService(LightsService.class); // 启动LightsService系统服务

    // Display manager is needed to provide display metrics before package manager
    // starts up.
    mDisplayManagerService = mSystemServiceManager.startService(DisplayManagerService.class); // 启动DisplayManagerService系统服务

    // We need the default display before we can initialize the package manager.
    mSystemServiceManager.startBootPhase(SystemService.PHASE_WAIT_FOR_DEFAULT_DISPLAY); // 等待Display有默认显示 // 调用DisplayManagerService的onBootPhase方法

    // Only run “core” apps if we’re encrypting the device.
    String cryptState = SystemProperties.get(“vold.decrypt”); // 当设备正在加密时,仅运行核心应用程序
    if (ENCRYPTING_STATE.equals(cryptState)) {

    Trace.traceEnd(Trace.TRACE_TAG_SYSTEM_SERVER);

    // Initialize attribute cache used to cache resources from packages.
    AttributeCache.init(mSystemContext); // 初始化属性缓存

    // Set up the Application instance for the system process and get started.
    mActivityManagerService.setSystemProcess(); // 先将ActivityManagerService注册到ServiceManager,然后向SystemManager注册几个其他服务,最后创建了一个代表system_server的ProcessRecord对象

    // The sensor service needs access to package manager service, app ops
    // service, and permissions service, therefore we start it after them.
    startSensorService();  // 启动传感器系统服务
}

1.5 startCoreServices

private void startCoreServices() {
    // Tracks the battery level.  Requires LightService.
    mSystemServiceManager.startService(BatteryService.class); // 启动BatteryService系统服务,用于统计电池电量信息

    // Tracks application usage stats.

    mPackageManagerService.getUsageStatsIfNoPackageUsageInfo();

    // Tracks whether the updatable WebView is in a ready state and watches for update installs.
