If geny doesn't start under Ubuntu

If you use Linux, make sure that the dkms package is installed and that it compiles VirtualBox kernel modules each time a new kernel update is available. To do so, run 
sudo /etc/init.d/vboxdrv status
You should get the message VirtualBox kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) are loaded. 
If not, force VirtualBox kernel modules compilation by running
sudo /etc/init.d/vboxdrv setup 
Make also sure that you are part of the "vboxusers" group. If not, run 
sudo usermod -a -G vboxusers <login>

Выполнение AsyncTask - onPostExecute не выполняется

Интересный случай.
AsyncTask запускается внутри View.
Фоновая работа проходит успешно, но метод onPostExecute или выполняется через неприлично долгое время или вообще не выполняется.
Решение - создавать и запускать AsyncTask в методе post объекта android.os.Handler, полученного в Application.
Вынести создание таска в активити.

Start server from point where you have right to write.
For example you can create folder for database in home folder (for me it's /home/alxr):

Now you can run:

Leave this window alone. Server works, any further movements you should do in other  windows.

Ormlite single quote issue solution

Correct way to implement com.j256.ormlite.stmt.Where<T, ID>:

you should use com.j256.ormlite.stmt.SelectArg object instead of using Object
SelectArg arg = new SelectArg();
titleArg.setValue(value);
Where<T, ID> where = where.eq(fieldName, arg);

Using this way you will avoid this issue http://stackoverflow.com/questions/26254896/android-ormlite-selectarg i.e. if  String value contains single quote.
