1. Version: May 2019
Pros & Cons of exiting Cross
Platform Frameworks

2. ReactNative

3. Advantages
3
 Time Efficiency
– hot reloading
 Performance
- Native API’s , separate thread from UI
 Growing Community
- Opensource and more developer community
 Third party plugin support
- some components are not in the main
framework.
 Save Money
- Short team size
 Reliable and Stable Apps
- allowed components will be upgraded.
 Target Multiple OS
-Less Native Code
 Supported Versions
-Android 4.1 (API 16) or newer and iOS 9.0

4. Dis - Advantages
4
 Ready made components
– Small collection
 Native code required
- to access device hardware
 App performance
- advanced functionality
 Component quality
- 3rd party libraries
 Steep Learning curve
- JSX (html +js).
 Low Security
- Java script based library
 Memory management
- Not suited for computation intensive apps
 Larger App Size
- Basic “hello world” app is 7 MB in size  than java(539 KB)
and Kotlin (550 KB)

5. Xamarin

6. Advantages
6
 Performance
–close to Native
 Native user experiences
- converts UI components at runtime using
Xamarin. Forms tool
 Hardware Support
- Plugin support available with little overhead
 Open source Technology with Corporate support
-SDK , Forms and Mono runtime are opensource on GitHub
 Xamarin. Forms
- Simple apps and Prototypes , Live Player
 Build Native apps
- Xamarin / Xamarin. Android
 Xamarin University
- e-Learning portal
 Supported Versions
- Android 4.0 (API 16) or newer and iOS 6.0

7. Dis - Advantages
7
 Slightly delayed support
– impossible for 3rd party tools to provide immediate support
for the latest iOS and Android releases.
 Limited access to Opensource Libraries
- payment services,beacons,wearable integration etc..
 Xamarin Ecosystem Problems
- Community is 10% of the global mobile society
 Basic Knowledge of Native Languages Required
- Platform specific layer of code
 Not Suitable for Apps with Heavy Graphics
- no rich UI or complex animations
- not suitable for the development of graphically-intensive
apps.
 Larger App Size
- Basic “hello world” app is 16 MB in size  than java(539 KB)
and Kotlin (550 KB)
 Compatibility Issues with Third-Party Libraries and
Tools
- Xamarin compliance might not be provided by the vedor.
-

8. Flutter

9. Advantages
9
 Speeds up coding and prototyping
–Hot Reload
 Great performance
- No JavaScript bridge for reactive views
 No compatibility issues
- Widgets are rendered part of the app , not the platform
 Open source
-Customization is available
 Ready-made and custom widgets
- fast UI coding
 Dart language
- AoT and JIT compilation,no JS bridge and no XML files
 Supported Versions
-Android Jelly Bean, v16, 4.1.x or newer, and iOS 8 or
newer.

10. Dis - Advantages
10
 Lack of third-party libraries
- Relatively new (released (V1.0) on Dec 4, 2018)
 Larger App Size
- Basic “hello world” app is 6.7MB in size  than java(539
KB ) and Kotlin (550 KB)
 Issues with iOS
- Delay in the latest release features, app store publishing
issues
 New Language
- Less community support

11. Cordova

12. Advantages
12
 Familiar with the web technologies
–HTML, JavaScript and CSS
 Plugin Support
- using JavaScript Wrapper
 Build Management
- it own config file
 Open source
-No licensing costs
 Community Support
- it has a huge and vibrant community
 Provides a layer
- Interface to the native code conversion
 Supported Versions
-Android 4.4.x or newer, and iOS 9 or newer.

13. Dis - Advantages
13
 Plugins
- In many cases, developers that have chosen to work with PhoneGap have done
so to avoid having to work with native-specific attributes
 Performance
 - Issues may sometimes arise if there are too many graphics or complex elements
in the app’s architecture, causing the app to become non-responsive or even crash
 Not suitable for hardware intensive apps
 Memory Loss
- Because PhoneGap lacks cache/memory management capabilities, loss of
memory is often an issue.
‾ Larger App Size
>8MB
