list<task> contactTask=new list<task>();
list<contact> consList=[select id,name,(select id from applications__r) from contact where id=:contactId];
    list<Task> tsk=[select id,whoId from task where whoId=:consList[0].id];

<aura:component implements="flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes"
access="global" controller="ContactActivityHistory">

<aura:attribute name="recordId" type="Id"/>

<aura:attribute name="newTask" type="Task" default="{'sobjectType':'Task'}"/>
<aura:attribute name="tasks" type="Task[]"/>
<aura:handler name="init" value="{!this}" action="{!c.doInit}" />

<aura:iteration items="{!v.tasks}" var="item">

Js.
({

doInit : function(component, event, helper)
{
console.log('Test activity');
var action = component.get("c.getContactTask");
console.log('Test Activity @@@@');
// var action=component.get('v.recordId');
console.log(component.get("v.recordId"));
action.setParams({
ContactId : component.get('v.recordId')
});

console.log('Test my contact record activity ' +component.get('v.recordId'));
action.setCallback(this, function(response) {
var state = response.getState();
if(state === "SUCCESS"){
// var records = response.getReturnValue();
// console.log('Server-> ' + JSON.stringify(records));
alert("From server: " + response.getReturnValue());
var newItems=[];
for (var i=0; i< records.length; i++)
{
var record = records[i];
console.log('record-> ' + JSON.stringify(record));

// var Item = {title: record.Name, id: record.Id, status: "Unassigned"};
// console.log('Item-> ' + JSON.stringify(Item));

newItems.push(record);
console.log('newItems-> ' + JSON.stringify(newItems));
}
component.set("v.tasks", newItems);


}
else if (state === "ERROR") {
var errors = response.getError();
if (errors) {
if (errors[0] && errors[0].message) {
console.log("Error message: " +
errors[0].message);
}
}

}

});
$A.enqueueAction(action);


}
})
