I have a "normal" Android app, made in Eclipse/java, published in Play Store, already at version 3.x, all works fine.
Now I am thinking to move the project to Xamarin/c#, and make the 4.0 there.
My question, what should I take care/be aware, that this change should be a natural continuation of the 3.x from Google Play/Users perspective?
So that I could simple upload the APK made by Xamarin to Dev Console as a new version upgrade, and not as a new App.
Like:
Existing signing key should be reused in Xamarin?
Package name (java <> xamarin c#) must be the same?
???
Thanks
There is absolutely no difference for google what language you natively used to write an app. By the way Xamarin will be compiled to java before packaging into apk.
Also Xamarin uses the installed Android SDK and installed Java SDK you have used before to sign the apk and compile the app. It also is going to use same keys so sign the apk.
So no worries, keep same package name and you're good for the update.

i have just finished coding of my android app and it is time to built it's apk but i want to create it's iOS version ipa to. i know i have to work on XCode on MAC for getting it's ipa output but i don't have any iOS device. nothing about Apple. so i want to use alternative ways like CodeMagic but i am new on development so it seems creating an ipa output will take a long time for me. in addition i didn't make any stuffs needs to be done for an iOS app can launch. for example i am using Firebase services but i only made it's android settings, didnt set anything about it's iOS version. so i have to do lots of things for creating my flutter project's iOS version and need time. at this point i have a question:
Can i built my app's iOS version after creating it's android version without make any settings for iOS? i want to built it's android apk or appbundle as soon as possible and i want to do it's iOS settings and built it's ipa later. is that possible? thaks for your helps.
Based on my experience... you'll have to setup the iOS separately to successfully build it.
For example when using firebase you'll need to add the GoogleServices file using Xcode.. or when using google maps you'll also need to add the api key on the appdelegate file.
I have a native app. I write it on JAVA. My apps is shared on google play store so, if i going to write my app again with flutter and i give same package_name this new flutter app. Can i update my app or i musn't change it to flutter ?
You can upgrade as long as it is signed with the same key and has a larger version number than your native app. Do not forget to keep compatibility with the file system of your current app, since if you use a database, for example, it should be accessed in the same way in your Flutter app.
To be sure, try an upgrade by uploading an alpha version of Google Play and upgrading to your own device.
I am still a beginner and I really don't know much and am working on my first app on android studio.
So is it possible to publish android studio project on iPhone App Store? If not is there any other way to do that?
You cannot publish a packaged compiled .apk Android Package file to an IOS app store. But an IPA file to IOS store
Google Play: - For Google play store you need to register for a Google play dev console account, plus a stock & rooted version of Android latest OS build phone
See this
Apple Store: - You need to have a Mac, plus an Apple developer license. A code editor like XCode, a know-how of programming language like Swift 3, an SDK toolkit & an iPhone
See Link1 and Link2.
android application is mainly build based on java program. ios application is build based on objective C.Its not because of programming language but rather due to final package its get compressed.
You can try learning xamarin cross platform native app development.
or
use ionic 2 framework. App Development based on HTML5,jss,css. Which use simple webview to display the content. That can be converted to any platform.
There is no way to do it as both have platform specific. So use their respective platform so audience can reach easily.
Mixing up of different platform caused confusion so follow each website rules.
I have an Android app on the Play Store, built in Xamarin. I'm going to rewrite using Java and Android Studio - is there anything stopping me from updating/switching language on my already-published app?
You just need to make sure to use:
the same Package Name
the same signature you signed the old one with
a bigger Version Code than the previous one.
I am a newbie to Android programming and i started putting together an application using Google Maps using Eclipse with KitKat SDK. I developed a simple app to display Google Maps in the Emulator by installing com.android.vending(4.6.16) and com.google.android.gms(4.3.25) apks. I downloaded these APKs from different sites(not sure how authentic they are).
I am making use of the command aapt dump badging to determine the version.
The map opens but i was repeatedly getting a message that "Unfortunately Play Services has stopped"
Objective is to ensure that I am using the right set of APKs with the emulator
The trouble that i am facing is there seems to be no clear directives on where i can find the authentic version of these APKs. I tried Google Play and when i give a search for com.google.android.gms, it yields a result of applications. I was expecting a URL to download the recent version of the APK. Correct me if i am wrong
1. How to download just the recent version of APKs from Google Play ? Am i looking at the correct site
2. Second is there any authorized site from where i can download these APKs?
I was looking for a listing of the APKs with the version number against it. So that i can download the version that i need. I am not sure of the dependencies of the APKs on the Android platform.
3. Finally is there any dependency between com.google.android.gms.apk and the com.android.vending.apk on the basis of the version or the SDK platform used?
Thanks

I have a suggestion, Try to use Genymotions for testing maps/places app. it is faster than emulator and you can build and check maps application.
