 **Table 1** Ability call APIs
 |API|Description|
 |:------|:------|
-|Promise<Caller> startAbilityByCall(want: Want)|Obtains the caller interface of the specified ability and, if the specified ability is not running, starts the ability in the background.|
-|void on(method: string, callback: CalleeCallBack)|Callee.on: callback invoked when the callee registers a method.|
-|void off(method: string)|Callee.off: callback invoked when the callee deregisters a method.|
-|Promise<void> call(method: string, data: rpc.Sequenceable)|Caller.call: sends agreed sequenceable data to the callee.|
-|Promise<rpc.MessageParcel> callWithResult(method: string, data: rpc.Sequenceable)|Caller.callWithResult: sends agreed sequenceable data to the callee and returns the agreed sequenceable data.|
-|void release()|Caller.release: releases the caller interface.|
-|void onRelease(callback: OnReleaseCallBack)|Caller.onRelease: registers a callback that is invoked when the caller is disconnected.|

 3. Send agreed sequenceable data.
 
-The sequenceable data can be sent to the callee with or without a return value. The method and sequenceable data must be consistent with those of the callee. The following example describes how to invoke the **Call** API to send data to the callee. The sample code snippet is as follows:
