本文介绍了LocationManager中的sendExtraCommand方法，该方法允许向位置提供者发送额外命令，以支持特定于提供者的LocationManager API扩展。文章提供了使用此方法进行快速定位及冷启动等操作的具体示例。

研究LocationManager发现方法：

public boolean sendExtraCommand (String provider, String command, Bundle extras)

Added in API level 3

Sends additional commands to a location provider. Can be used to support provider specific extensions to the Location Manager API

Parameters

provider	name of the location provider.
command	name of the command to send to the provider.
extras	optional arguments for the command (or null). The provider may optionally fill the extras Bundle with results from the command.

Returns

true if the command succeeds.

示例：

LocationManager locationmanager = (LocationManager)context.getSystemService("location");
        Bundle bundle = new Bundle();
        locationmanager.sendExtraCommand("gps", "force_xtra_injection", bundle); //快速定位command
        locationmanager.sendExtraCommand("gps", "force_time_injection", bundle);
        locationmanager.sendExtraCommand("gps", "delete_aiding_data", bundle); //冷启动
