2.1 # SystemServer.java
/** 291 * The main entry point from zygote. 292 */ 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();
