java - Saving on sql using active android not actually saving -

everyone i've using activeandroid library in android avoid doing sql coding reason isn0t working

here code:

this manifest:

<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.read_external_storage" />  <application     android:name=".myapplication"     android:allowbackup="true"     android:icon="@mipmap/ic_launcher"     android:label="@string/app_name"     android:theme="@style/apptheme">      <meta-data         android:name="aa_db_name"         android:value="knownfiles2.db"/>      <meta-data         android:name="aa_db_version"         android:value="5"/>      <activity         android:name=".mainactivity"         android:label="@string/app_name" >            <intent-filter>             <action android:name="android.intent.action.main" />              <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity> </application> 

this myapplication class

    public class myapplication extends application { @override public void oncreate() {     super.oncreate();      activeandroid.initialize(this); } 

}

this folders model

    @table(name="folders") public class folder extends model implements serializable{ @column(name="path") public string path;  @column(name = "showallimages") public string showallimages;  folder() {     super(); }  folder(string path, string showallimages) {     super();      this.path = path;      this.showallimages = showallimages; }  @override public string tostring() {     return "path: "+path+             " showallimages "+showallimages; } 

}

this servers model

    @table(name = "servers")     public class server extends model implements serializable{  @column(name = "ip") string ip;  @column(name = "folder") folder folder;  server() {     super(); }  server(string ip, folder folder) {     super();     this.ip = ip;      this.folder = folder; }  @override public string tostring() {      return "ip: "+ip+" folder: "+folder.tostring(); }  public list<server> getserver() {     return getmany(server.class, "ip"); } 

}

and code i'm trying working:

       folder folder = new folder("private/secret/","show-all-images.php");                  folder.save();                  server server = new server("192.168.1.191",                         folder);                 server.save();                  log.v("mytag",server.getid()+"");                  log.v("mytag",server.tostring());                  log.v("mytag","added");                  arraylist<server> data = new select()                         .all()                         .from(server.class)                         .execute();                  log.v("mytag", data.size()+"");                 (server serverloop:data) {                     log.v("mytag", serverloop.tostring());                 } 

the log should return elements in database, doesn't because says size of arraylist carrying data 0

here log: 04-09 22:59:30.824 27608- 27608/com.example.mariomarhuendabeltran.photokeeper v/mytag﹕ 5 04-09 22:59:30.824 27608-27608/com.example.mariomarhuendabeltran.photokeeper v/mytag﹕ ip: 192.168.1.191 folder: path: private/secret/ showallimages show-all-images.php 04-09 22:59:30.824 27608-27608/com.example.mariomarhuendabeltran.photokeeper v/mytag﹕ added 04-09 22:59:30.824 27608-27608/com.example.mariomarhuendabeltran.photokeeper v/mytag﹕ 0

as can see adding successful, list empty. 5 reveals element added fifth in database

help please!! in advance

you need define models in manifest well,

in manifest add this:

<meta-data     android:name="aa_db_name"     android:value="knownfiles2.db"/>  <meta-data     android:name="aa_db_version"     android:value="5"/>  <meta-data         android:name="aa_models"         android:value=".yourmodel1, .yourmodel2" /> 

i hope helps. other parts of code seems fine me
