360Replugin插件启动Activity慢导致ANR的问题

0x01. classloader

打印classloader

        try {            ClassLoader loader = getClassLoader();            if (loader != null) {                LogUtils.e(TAG, ">>><<< loader:" + loader.toString());                loader = loader.getParent();                if (null != loader) {                    LogUtils.e(TAG, ">>><<< loader:" + loader.toString());                }            }        } catch (Exception e) {            e.printStackTrace();        }

Replugin的classloader信息:插件信息,插件so库信息,系统库信息.

启动插件中的Service:

    // 启动插件Service。说明见PluginServiceClient的定义    ComponentName startServiceLocked(Intent intent, Messenger client) {        intent = cloneIntentLocked(intent);        ComponentName cn = intent.getComponent();//        ProcessRecord callerPr = retrieveProcessRecordLocked(client);        final ServiceRecord sr = retrieveServiceLocked(intent);        if (sr == null) {            return null;        }        if (!installServiceIfNeededLocked(sr)) {            return null;        }        sr.startRequested = true;        // 加入到列表中，统一管理        mServicesByName.put(cn, sr);        if (LOG) {            LogDebug.i(PLUGIN_TAG, "PSM.startService(): Start! in=" + intent + "; sr=" + sr);        }        // 从binder线程post到ui线程，去执行Service的onStartCommand操作        Message message = mHandler.obtainMessage(WHAT_ON_START_COMMAND);        Bundle data = new Bundle();        data.putParcelable("intent", intent);        message.setData(data);        mHandler.sendMessage(message);        return cn;}

这里如果第一次启动Service是从工作线程则直接延迟6秒!!!

    // 判断是否已加载过Service对象，如无则创建它    private boolean installServiceIfNeededLocked(final ServiceRecord sr) {        if (sr.service != null) {            return true;        }        try {            Boolean result = ThreadUtils.syncToMainThread(new Callable<Boolean>() {                @Override                public Boolean call() {                    return installServiceLocked(sr);                }            }, 6000);//这里如果不是从主线程启动的service则延迟6秒            if (result == null) {                return false;            }            return result;        } catch (Throwable e) {            if (LOG) {                LogDebug.e(PLUGIN_TAG, "pss.isinl e:", e);            }            return false;        }}
