二、Service not registered 解决方案

一、Service not registered 异常导致手机重启

1.重启 的部分Log如下：

Service not registered 重启异常

二、Service not registered 解决方案

从 Log 中分析发现异常信息，并尝试进行如下修改。

1.修改ContextImpl类

文件路径如下：
\frameworks\base\core\java\android\app\ContextImpl.java文件

优化unbindService方法实现如下：

@Overridepublic void unbindService(ServiceConnection conn) {if (conn == null) {throw new IllegalArgumentException("connection is null");}if (mPackageInfo != null) {IServiceConnection sd = mPackageInfo.forgetServiceDispatcher(getOuterContext(), conn);try {ActivityManager.getService().unbindService(sd);} catch (RemoteException e) {throw e.rethrowFromSystemServer();// add for Service not registered unbindService() triger reboot exception} catch (IllegalArgumentException e) {//com.google.android.gms.ui Service not registered Crashandroid.util.Log.e("wjwj","---ContextImpl GMS Crash---");e.printStackTrace();}// add for Service not registered unbindService() triger reboot exception} else {throw new RuntimeException("Not supported in system context");}}

2.修改 TransportManager 类

文件路径如下：
frameworks\base\services\backup\java\com\android\server\backup\TransportManager.java 将异常捕获，防止重启。

优化unbindService方法实现如下：

void onPackageRemoved(String packageName) {// Package removed. Remove all its transports from our list. These transports have already// been removed from mBoundTransports because onServiceDisconnected would already been// called on TransportConnection objects.synchronized (mTransportLock) {Iterator<Map.Entry<ComponentName, TransportConnection>> iter =mValidTransports.entrySet().iterator();while (iter.hasNext()) {Map.Entry<ComponentName, TransportConnection> validTransport = iter.next();ComponentName componentName = validTransport.getKey();if (componentName.getPackageName().equals(packageName)) {TransportConnection transportConnection = validTransport.getValue();iter.remove();if (transportConnection != null) {/* 360OS begin *//* unbindService() triger reboot exception,* catch it && add log to find out witch package do it. */try {Slog.d(TAG, "onPackageRemoved trace, componentName:"+ componentName.toString(), new Throwable());mContext.unbindService(transportConnection);} catch (IllegalArgumentException e) {Slog.e(TAG, "unbindService fail.", e);}/* 360OS end */log_verbose("Package removed, removing transport: "+ componentName.flattenToShortString());}}}}}
