Can you publish an app made with android studio to iOS platforms? Is there a compiler that lets you compile your Android Studio app to and iOS platform working app?
It is not practical to run Android apps on iOS or the other way round.
Each operating system of each platform has different native components. The native Android or iOS app development requires using different programming languages, design interface, navigation, integration process.
The Android system uses the instruction set of the Java virtual machine called ByteCode. iOS, on the other hand, implements the compiled code.
Running Android apps on iOS is not possible because of the following factors:
Different lifecycle of apps in the system.
Different lifecycle of app screens within the app itself.
Different approaches regarding data access.
It is misleading to be told to use some kind of service or program to transfer your app to another platform with just a few clicks. Online tools like an Android to iOS converter do not work.
The only exception is the case if your app has been developed cross-platform from the beginning. There are some web-based libraries and frameworks which can help you develop hybrid apps. You can also have a look at flutter & xamarin but the app must be all done in that framework.
As far as I know, there is no something that can do that. Android is very different from IOS. If you want, there are a lot of tools that you can develop with them apps for both Android and IOS, with one codebase.
Some of these tools:
React Native
Flutter
Xamarin
PhoneGap
Apache Cordova
But if you will use one of these tools, instead of Android Studio for Android and XCode - It will not have the same performance as if it was written with Android Studio and XCode.
The reason for that is because the platform-specific tool (Android Studio / XCode) can talk directly with the Operating System, while the cross-platform tool (React Native / Fultter etc.), cannot talk directly with the Operating System.
Hope I helped you!
You can do this with Flutter.
https://flutter.dev/
They are different from writing standard android apps, and use Dart rather than Kotlin/Java.
It does have a good tight integration with Android Studio however.
I just finished a course on php and java-script and I want to go into Android app development with pythons kivy but I want to know if it is possible to access native functionality geolocation,camera,vibrator,gallery,flash light and other android native features with kivy and how easily can I do it ..
i want to know if it is possible to access native functionality
Yes. Accessing a lot of native functionality is possible with Plyer - a library for accessing features of your platform's hardware.
Kivy does not have GPS functionality or Notifications, but since Kivy uses Python, you can import any Python library or framework into it.
Here's another link showing what functionalities and supported APIs you can get out of Plyer on each of the various platforms (Android, iOS, Mac, Windows, Linux).
kivy vs android studios vs hybrid which works best for beginners
It depends on the beginner. I would make a list of recommendations based on their background.
No background:
Learn Java (or Kotlin) and use Android Studio.
Any C-based background or OOP background:
Android Studio
Xamarin (C#) in Visual Studio
Any web or javascript background:
React Native
Android Studio
Iconic
PhoneGap
Any scripting background:
Kivy which can be setup in various IDEs.
Android Studio.
At the end of the day, my final recommendation would be to use Android Studio because it's the official IDE for Android app development.
Note: I currently use Android Studio, so I'm slightly biased towards it.
I am new to Xamarin, and ios apps, and a bit less new (however far from veteran) to Android apps.
Therefore, I would like to start developing my app for Xamarin.Android using Xamarin (also, that's my only phone, and the only thing I can test for at the moment), and be able to migrate the app sometime in the future to Xamarin's cross platform development.
Is this possible?
How is migrating an android only app to cross platform done?
Thanks
The recently launched react native features just iOS app example and docs.
Yes.
React Native for Android was released September 14th, 2015.
Docs: http://facebook.github.io/react-native/
No. You can't build Android apps with this release.
Facebook has indicated that they are working on an Android version, and famously said "give us 6 months", which some people have taken as a promise. I wouldn't base any important business decisions on the illusion that it will be unveiled when the 6 months is over, but you can at least take some hope in the fact that they're serious about making it production-ready before they give us access to it, and that it's not just a pie-in-the-sky hope.
Also, as others have pointed out, Facebook has already release apps that they've built with the Android version of React Native. So at least parts of it are ready for prime time.
UPDATE
Early support for React Native for Android has been pushed to GitHub!
As noted, there are several things that are currently not working if trying to port an application from iOS. But it's worth checking out.
https://github.com/facebook/react-native/commit/42eb5464fd8a65ed84b799de5d4dc225349449be
It is not aiming to be a cross platform, write-once run-anywhere, tool. It is aiming to be learn-once write-anywhere. -Colin Eberhardt, from Raywenderlich
Good news is that React Native for Android is finally here. (https://code.facebook.com/posts/1189117404435352)
while you can't do it right now, it shouldn't take that long.
The first React Native Android App has been published about two weeks ago in the play store as tweeted by the reactjs twitter account:
https://twitter.com/reactjs/status/615638361328349185
Great news! Now its possible!

I've tried out Facebook react native on Android and it really worked.
Simple Ubuntu install guide can be found here
Simple js files: link
Yes , We can now developed android apps too in react-native.
and some of the apps are already developed in react-native for android
suchs as:
1)F8
2)Facebook ads manager
3)Squad
4)Discovery VR
5)Ziliun etc..
and many more still counting.
Developers from around the world now opting react-native for mobile app development because of easy of use of JSX syntax.
and also it is commonly noted as simply the V in MVC.
Since React makes no assumptions about the rest of your technology stack, it's easily embeddable within an existing non-React Native app.
TLDR; Yes,
Detailed answer (As of November 2017)
React Native android application development is very stable and a good number of Android applications have been already built and used in production using React-Native.
You can find a showcase of applications here. Most of them have both IOS and Android versions.
You can also easily integrate your native Android java code to react-native. Refer here
As a developer who is building Android app using react-native with a lot of native java code dependencies, react-native runs stable and I found the documentation and community support is adequate.
Yes, it works for both the platforms ios and android, be sure to mention code entry points in app.js if it uses different code for different platforms. However native functions like native events or location manager need to be coded in native languages and then exported using RCT_EXPORT, you can find more about it in the docs
Sure,
Using React Native you can build real mobile app. real app means close to platform or simply can say 99% native app.react native provide easy way for building native android app using javascript for lucrative design.You have basic knowledge of android studio and error fixing in android studio related native module integration and good understanding of react.js then you can build android app using react native.
Basic Requirement for android app
1. Configure android studio please follow below link and avoid installation of python.
https://facebook.github.io/react-native/docs/getting-started .
2. for UI you will learn flex-box from official documentation.
I thing that is enough
Yes, not just with android but also with iOS using XCode
Yes, you can make real-world mob application with React-Native. React-Native is used to create a hybrid mobile application. In this, we write code in javascript which gets converted to swift for ios and java for android.
Yes, You can build the Android app using React Native. For this, you have to install Android Studio with all the required SDKs. You can run your React Native app in Android simulator by using Android Studio and command line both.
For command line, run the following command:
react-native run-android
Otherwise you can open the android project in Android Studio which is created by React Native in android folder and run the project from there.
Happy Coding.. :)
Yes, you can definitely build android apps using react-native.This is one of the great benefits of React Native. Before Facebook created it, you had to build your app twice and with different code : one for iOS using Swift or Objective-C and one for Android using Java or Kotlin.
Hello everybody I learn phonegap framework and I have few questions. I want to write app for android and ios. In android I write using Java and JavaScript so If I want to run it on other platform (like ios where is object-C) do I have to depend mostly on JS, move that code to MAC and build ios app??? I dont understand how to use my code in android and iOS... Do I need MAC? Do I need to know xcode?
If you are using cordova you have to use javascript/HTML/Jquery/Jquery Mobile/CSS, everything that you would use for the web.
Regarding the compilation if you have to work with IOS, you must have a MAC and then compile the project using xCode, but you do not need to know him well, you just need to know the process of publication.
For Android, you can instead use Ecplise.
If you want to develop cross-platform on an Android IDE, such as Eclipse then there is no need for a Mac & Xcode outside of testing. However, if you're saying that you already use Xcode and write in Obj-C then have a look at this tutorial to get you started:
