I provide the source code :
this is the main_page

<div class="grid2">
<div class="first" id="search_btn">
<div>
<img src="images/loupe.jpg"/>
<div>
</div>Search for a Spot</div>
</div>
<div class="second" id="submit_spot_btn">
<div>
<img src="images/spot.jpg"/>
</div>
<div>Submit a spot</div>
</div>
</div>
<ul style="margin:0 auto;" class="spaced_list" style="widht:280px;" >
<li><input type="button" data-role="none" value="Account info" class="btn" style="margin:0 auto;" id="main_page_account_info"/></li>
<li><input type="button" data-role="none" value="Log Out" class="btn" style="margin:0 auto;"id="main_page_log_out"/></li>
</ul>
</div>
here is the first_map page is named spot_page
<div data-role="page" id="spot_page" data-theme="b">
<div data-role="header" style="overflow:hidden;">
<img class="logo_icon" src="images/logo_icon.png">
</div><!-- header -->
<div class="clear"></div>
<div id="search_form_holder" style="margin:0px 25px" >
<p class="center" style="font-size:16px;font-weight:bold;">
Search for a Spot
</p>
<ul class="some_space" style="margin:0 auto;
margin-left:auto;
margin-right:auto;
align:center;
text-align:center;
width:280px;">
<li><input type="text" id="address_zip" class="field black" placeholder="Address/Zip Code"/></li>
<li id="to"></li>
<li><input type="button" data-role="none" style="width:200px;margin:15px auto;" id="search_spot_btn" class="btn" value="Search for a Spot"></li>
</ul>
<div id="hidden_scroller" style="display:none">
<select id="distance" name="Within">
<option value="1">1 Mile</option>
<option value="3">3 Miles</option>
<option value="5">5 Miles</option>
<option value="10">10 Miles</option>
</select>
</div>
</div><!-- search form -->
<div id="first_map" style="width: 100%;
height: 247px;border:1px solid black;margin:0 auto">
</div>
</div><!-- split view -->
and finally the second map here :
<div data-role="page" id="nearby_page">
<div data-role="header" style="overflow:hidden;">
<img class="logo_icon" src="images/logo_icon.png">
</div><!-- header -->
<div class="clear"></div>
<div class="second_header">Spots nearby</div>
<div id="map" style="width: 100%;
height: 398px;border:1px solid black;margin:0 auto">
</div>
</div>
As you can see the pages are separate from each other.
I have a last question could a navigation plugin help to fix the problem like jquery history plugin and thanks for your help.

Answer 1

Make sure to have your pages on different separate pages. If not these kind of errors will occur. Mostly, you will encounter abnormal navigation error. That is what I have experienced in my experience.
BTW, you should show more of your code for people here to help you out.
Update
PhoneGap and Android's back button do behaves odd. What I have done in my application is disabled the back button and given the soft back button on the top header. Simple history.back() will do the magic for back buttons.
You can disable as follows.
$(function(){
document.addEventListener("deviceready", onDeviceReady, false);
})
// PhoneGap is loaded and it is now safe to call PhoneGap methods
//
function onDeviceReady() {
// Register the event listener
document.addEventListener("backbutton", onBackKeyDown, false);
}
// Handle the back button
//
function onBackKeyDown() {
console.log("Back button pressed but nothing happened");
}
Anyway this is my approach. You may choose to be different.
