I am new for android. Recently upload an apk as alpha version on play store. now complete all testing in alpha .Now i want final alpha version as a production apk. It is possible?
Sign your app with a release key, check the Manually sign an APK for instruction. Anyway's the step-by-step instruction to finally publish it in Google play is found in Launch checklist.

my apk is 1.4MB but error is "This APK results in unused code and resources being sent to users. Your app could be smaller if you used the Android App Bundle. By not optimizing your app for device configurations, your app is larger to download and install on users' devices than it needs to be. Larger apps see lower install success rates and take up storage on users' devices."
how to fix this error
It's only a warning, not an error.
For an app that small I wouldn't worry.
It's not something that's made its way into the Ionic ecosystem yet but I heard that if you open up your project in Android Studio and then do the build through there you can create an app bundle.
I'm not totally sure that its fully tested for Ionic so you might have issues with this, but Android have published a full guide:
https://developer.android.com/guide/app-bundle#get_started
This is what they say:
Download Android Studio 3.2 or higher—it's the easiest way
to add dynamic feature modules and build app bundles.
Add support for Dynamic Delivery
by including a base module, organizing code and resources for configuration
APKs, and, optionally, adding dynamic feature modules.
Build an Android App Bundle using Android Studio.
If you're not using the IDE, you can instead build an app bundle from the
command line.
Test your Android App Bundle by using it to generate APKs that
you deploy to a device.
Enroll into app signing by Google Play.
Otherwise, you can't upload your app bundle to the Play Console.
Publish your app bundle to Google Play.
Here is the versions I am using
The problem is the project I created using react-native init AddisMereja is of size 20MB.
It does not have anything.
I believe you are talking about the size of the apk file that is generated. If so you can try using app bundle and submit the app bundle to google play store which will handle it according to users device as the apk that is generated by default contains apps for different architectures but you will end up using only one of them.
This blog post by Krzysztof Magiera explains the process better.
Your app size is descries after make a release apk Or sign apk.
I published my first app to AppStore last night.
I just want to know if there is code change in my app,
Should I have to re-build and upload .ipa file to itunes connect again?
(Currently, I do not use CodePush and I build app with exp)
Thanks.
Expo comes with a built in CodePush equivalent.
Whenever you publish to expo (using exp publish, the XDE etc), expo builds new JS bundles and uploads them to their servers.
Users who downloaded the app from the stores will get those updates - while iOS users will get them as soon as they open the app, Android users will get them in the second time (iOS is does this syncly while Android asyncly).
Note that this does not apply to changes in the app config (app.json), including sdk upgrades or any other configuration changes.
Yes, you will need to rebuild the release version of your app and upload to the App Store as a new version.
I have used expo to create a simple barcode scanner .When I generated the apk for the same .The apk size is extremely large compared to android studio.
this is explained in this expo documentation.
At the moment, expect the smallest APK to be ~25MB.
Ok, I have a problem with expo build. Please let me know if you need more details. Basically, the project I am working on is NOT detached. It is just using Expo.
So I publish it. Let's say the javascript bundle version is 0.17, and I am publishing a breaking change to 0.18.
When I load the app from Hockey App, the javascript bundle is clearly not 0.18 because I don't see my breaking changes. Then, I close the app and re-open it, and the JS bundle is updated.
The build script is:
exp build:android
[exp] Android:
[exp] APK: [AWS LINK] apk has been generated, it took 0 seconds
Then, I get an AWS link to the APK, which I download and upload to Hockey Apps.
How should I diagnose this problem?
Exp version is 44.0.0
It is the way it works in Android. First time you open your app after you publish, the code is downloaded in background. Next time it will run the new code.
Quoting the documentation:
Updates are handled differently on iOS and Android. On Android, updates are downloaded in the background. This means that the first time a user opens your app after an update they will get the old version while the new version is downloaded in the background. The second time they open the app they’ll get the new version. On iOS, updates are downloaded synchronously, so users will get the new version the first time they open your app after an update.
