As mentioned in the Javadocs, the method should be used only with a valid license
/**
* check if document can be modified or saved.<br/>
* this always return false, if no license actived.
* @return true or false.
*/
public boolean CanSave()
{
return canSave( hand_val );
}
So for testing purposes, you can either use the demo project (which is activated with premium license) or give your project "com.radaee.reader" as package name. (Eclipse:Right click you project -> Android Tools -> Rename Application package)
