293    public static void main(String[] args) {
294        new SystemServer().run();
295    }

上面是SystemServer的主函数。

private void run() {

// Start services.
427        try {
428            traceBeginAndSlog("StartServices");
429            startBootstrapServices(); // 在这个里面启动PMS
430            startCoreServices();
431            startOtherServices();
432            SystemServerInitThreadPool.shutdown();
433        } catch (Throwable ex) {
434            Slog.e("System", "");
435            Slog.e("System", " Failure starting system services", ex);
436            throw ex;
437        } finally {
438            traceEnd();
439        }

}

private void startBootstrapServices(){

...

traceBeginAndSlog("StartPackageManagerService");
628        mPackageManagerService = PackageManagerService.main(mSystemContext, installer,
629                mFactoryTestMode != FactoryTest.FACTORY_TEST_OFF, mOnlyCore);
630        mFirstBoot = mPackageManagerService.isFirstBoot();
631        mPackageManager = mSystemContext.getPackageManager(); 

...

}
