Description
This app is an Android version of QL, a Domain Specific Language for QuestionnairesA DSL for auto-generated interactive questionnaire sheets. Questionnaires are characterized by conditional entry fields and (spreadsheet-like) dependency-directed computation. It reads from a text file the content(source code), conducting lexical and syntactic analysis, and auto-generates interactive Android UI Views. The application allows the user to export in PDF format the results of the filled form, and view them via the default PDF Viewer app of the smartphone device. ANTLR java parser and the java programming languages is used for the implementation of this project.
Example
The following example presents a possible textual representation of a simple questionnaire.
form Box1HouseOwning {
hasSoldHouse: “Did you sell a house in 2010?” boolean
hasBoughtHouse: “Did you by a house in 2010?” boolean
hasMaintLoan: “Did you enter a loan for maintenance/reconstruction?” boolean
if (hasSoldHouse) {
sellingPrice: “Price the house was sold for:” money
privateDebt: “Private debts for the sold house:” money
valueResidue: “Value residue:” money(sellingPrice - privateDebt)
}
}
This simple form should generate into a GUI.

Syntax
QL consists of questions grouped in a top-level form construct. First, each question identified by a name that at the same time represents the result of the question. In other words the name of a question is also the variable that holds the answer. Second, a question has a label that contains the actual question text presented to the user. (Note that technically this is a presentation issue that could be in a separate language for layout and styling, but to make QL standalone we need it here. See below for more on the layout language.) Third, every question has a type. Finally, a question can optionally be associated to an expression: this makes the question computed. A questionnaire consists of a number of questions arranged in sequential and conditional structures, and grouping constructs. Sequential composition prescribes the order of presentation. Conditional structures associate an enabling condition to a question, in which case the question should only be presented to the user if and when the condition becomes true. The expression language used in conditions is the same as the expressions used in computed questions. Grouping does not have any semantics except to associate a single condition to multiple questions at once. For expressions we restrict ourselves to booleans (e.g., && , || and ! ), comparisons ( < ,> , >= , <= , != and == ) and basic arithmetic ( + , - , * and / ). The supported types are:boolean, string, integer,and money/currency.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
