H類處理的message是從哪傳遞回來的呢？
case?LAUNCH_ACTIVITY:?{
????????????????????Trace.traceBegin(Trace.TRACE_TAG_ACTIVITY_MANAGER,?"activityStart");
????????????????????final?ActivityClientRecord?r?=?(ActivityClientRecord)?msg.obj;
????????????????????r.packageInfo?=?getPackageInfoNoCheck(
????????????????????????????r.activityInfo.applicationInfo,?r.compatInfo);
????????????????????handleLaunchActivity(r,?null);
????????????????????Trace.traceEnd(Trace.TRACE_TAG_ACTIVITY_MANAGER);
????????????????}?break;

我覺得應該是ActivityManagerService傳遞過來的吧，我自己的感覺是ActivityManagerService遠程控制了整個過程。我也同樣疑惑，只是說出自己的理解罷了，希望能和大家討論下
