某些進程延遲啓動

每個進程的啓動都會經過startProcessLocked 這個函數。爲了加快啓動速度，某些應用可以後續再啓動

 if (NWD_SPEED_UP) {
            final String pkgName=app.info.packageName;

                mOtherAppProcessInfos.add(procInfo);
                return;
            }
        }

    }

 

 

再systemReady準備完成後，需要註冊和發送廣播。

 

 IntentFilter filter = new IntentFilter();
filter.addAction("start.other.app.service");
filter.addAction(Intent.ACTION_UI_BOOT_FINISH);
 mContext.registerReceiver(new BootCompletedReceiver(), filter);

sendBootCompletedBroadcast();
