jquery mobile - Phonegap android project works on emulator and in some devices but not in a 2.2 android device -

im making phonegap application (phonegap 2.9 + jquery 1.8.3 + jquery mobile 1.3.1) works in: -4.3 android device. -4.0 android device. -2.2 android virtual device.

the problem im having issues when install in android 2.2.2 device. of api calls work , others dont.

for example, call works:

$.ajax({     data:   {museum_id:'1'},     url:    url+'index.php?r=api/listallcuriosities',     type:   'get',     success:  function (response) {         var resultado = response['data'];         var listadohtml = '';         (var i=0;i<resultado.length;i++){             listadohtml += '<ul data-role="listview" data-theme="b" class="titulos"><li>'+resultado[i]['title']+'</li></ul>'                         +'  <p>'+ resultado[i]['description']+'</p>';         }          $('#listcuriosities').html(listadohtml);         $('#listcuriosities').trigger('create');     },     error: function() {         //something went wrong, handle error , display message         alert('se ha producido un error en la llamada al servidor');     } }); 

but other doesn't

$.ajax({     data:   {museum_id:'1'},     url:    url+'index.php?r=api/listmasterpieces',     type:   'get',     success:  function (response) {         var visitedlist = json.parse(window.localstorage.getitem("visited"));         var resultado = response['data'];         var listadohtml = '<div>';         var author = '';           (var i=0;i<resultado.length;i++){             var item = '';             var isvisited = 'data-theme="a"';              if(visitedlist!=null && resultado[i]['id'] in visitedlist && visitedlist[resultado[i]['id']]==1){                 isvisited = 'data-theme="b" data-icon="check"';             }              if(resultado[i]['authorname']!=author){ // en caso de que el autor haya cambiado se insertará una nueva línea                 item += '<ul data-role="listview" data-theme="b"><li>'+resultado[i]['authorname']+'</li></ul>';                 author = resultado[i]['authorname'];             }             var id = resultado[i]['id'];             item += '<p><a href="detalle.html?id='+id+'" id="enlace-'+id+'" data-role="button" data-ajax="false" data-prefetch="false" '+isvisited+'>'+resultado[i]["name"] + '</a></p>';              listadohtml += item;         }         listadohtml += '</div>';           $('#listamasterpieces').html(listadohtml);         $('#listamasterpieces').trigger('create');     },     error: function() {         //something went wrong, handle error , display message         alert('se ha producido un error en la llamada al servidor');     } }); 

i think can be: -because of a permissions problem (as can see store information in device) -because jquery doesnt work (i dont see alert of error ajax-method)

i attach manifest:

<supports-screens android:largescreens="true" android:normalscreens="true" android:smallscreens="true" android:resizeable="true" android:anydensity="true" />   <uses-permission android:name="android.permission.read_phone_state" />  <uses-permission android:name="android.permission.internet" />  <uses-permission android:name="android.permission.write_external_storage" />  <uses-sdk     android:minsdkversion="8"     android:targetsdkversion="17" />   <application     android:allowbackup="true"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme" >     <activity         android:name="com.museum.prado.mainactivity"         android:label="@string/app_name"          android:configchanges="orientation|screensize" >         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>  </application> 

thanks in advance

thanks @raoul george discovered problem.

when make:

var visitedlist = json.parse(window.localstorage.getitem("visited")); 

in android 4 nothing happens, if work android 2.2 need sure window.localstorage.getitem("visited") has value.
