Detailed Description

Core of Learn Spellings template.

Definition at line 43 of file learnspellingscore.h.

Member Function Documentation

TemplateCore::GenerationResult LearnSpellingsCore::generateMobileApplication ( const QString &  input_apk_file, QString &  output_file  )

virtual

Generates APK file from current project with active settings.

Returns

Returns true on success, otherwise returns false.

Warning

This is used only if template can actually generate mobile application, so that editor of the template must contain sufficient data for doing so.

Implements TemplateCore.
