MyAppConverter is a powerful service that helps developers convert native iOS mobile apps instantly to native Android app, it's not focused mainly on the look and feel, and UI interaction of your app. That means we don't replicate your application as it is. Instead, MyAppConverter make all changes to make a project suitable for the development of an Android application. MyAppConverter currently support only iOS to Android conversion and objective-c to swift.

6. As Developers, why would you care?
• Total freedom to develop on your favourite platform without limiting
yourself to other platforms
• Your converted code is fully documented & readable
• Being platform and technology agnostic, we guarantee the
scalability of your code
• Enabling open source mapping will allow developers to benefit from
all the technologies and market innovation across all platforms
• You will be part of an active, vibrant and global community of
developers across borders and technologies
• You want to create mobile apps that can be available to anyone,
anywhere no matter what the smartphone is and with the best UX

8. Ios Applications Lifecycle
An iOS application goes through a set of states as it runs.
As an app moves through the states of its lifecycle, the state of the app is defined by
its level of activity such as Not Running, Active or Suspended.

9. Generated Android Lifecycle
The generated android application is event driven and goes
throw a set of the following set of events

10. The native structure of the mobile
applications :IOS
• The Ios application structure follow a model view Controller pattern .

11. The native structure of the mobile
applications :IOS
• The UIApplicationMain function in the project sets up several key objects and starts the app
running.
• At the heart of every iOS app is the UIApplication (AppDelegate) object, whose job is to
facilitate the interactions between the system and other objects in the app.
• The AppDelegate start the initial view controller and load its UI elements from the
main.storyboard or the equivalent .xib file.
• Using MyAppConversion service gets you an android studio project that have an almost
equivalent structure.

12. The native structure of the mobile
applications :Android
• The resulted android app process start by instantiating the Application object, and
then start the LauncherActivity.
• The LauncherActivity uses the Application instance to start the initial view
controller, and load its view and finally add it to the LauncherActivity view

13. Mappings method signatures
• The generated java method name the concatenation of iOS
method name and the aliases
• The first letter of each alias is capitalized.
• The types of the parameters in iOS are converted to their
mapped equivalent.

14. MyAppConverter language Syntaxes
Mappings
• Classes
• Categories
• Enums
• Structs
• Pointers
• Memory management
• Blocks
• Protocols
• Primitive types
• Data structures
• Casting
• Typedef
• Macros
When converting objective c to java MyAppConverter takes care of all the
following aspects of the language. The Mapping knowledge base provide an
implementation for each element of the following in the target platform

15. MyAppConverter Mapping Platform
differences
• Density-independent pixels (dp) and design in
vector at 1x
– On Android, the key unit of measure is the
density-independent pixel
– When converting from Ios MyAppConverter
transforms points on iOS and CSS pixels to DPs.
– Measuring and sizing things in DPs ensures your
designs have a consistent physical size across
devices of varying density.

16. MyAppConverter Mapping Platform
differences
• The system Back button
Android phones have a back button, which can be used to return to previous screens
in the app.
iPhones don’t have this button, this is
usually done by a “back” chevron in the top
left of the screen, MyAppConverter
Convert itto a back button and mapps the
android back button to the same event

17. MyAppConverter Mapping Platform
differences
• Bottom tabs
– On iOS, it’s common to use a bottom tab bar to switch between views in the
app. Android’s platform convention is to display tabs for view control at the
top of the screen instead. In addition, Android apps may use bottom bars to
display actions.
• Gestures
– Offering touch gestures to operate your app is a great way to make the
experience fast, fluid and delightful. You should always be mindful of user
expectations for gesture-based interaction on a platform. On Android, most of
the common gestures have very standardized behaviors, so users will expect
your app to support those. There’s an entire section in the material design
guidelines covering gestures, but it’s most important to get a couple of the key
gestures right.
