我可以在 alpha 测试通道的生产中使用较低版本的代码吗

Question

I need to publish my application first at alpha testing channel at play developer console and then to production. Lets say that I publish the application at alpha with version code 1.0.0. After testing it, I need to publish updates of the application so I increase the version code to 1.0.1, 1.0.2, etc.

1. After I finish testing, can I upload a new apk to production with an initial version code 1.0.0? I don't want to promote the apk published at the alpha channel that will have an increased version code ie 1.0.5. Will that cause any issues?

2. Do you have any other recommendation how to handle this case?

Thanks,

Lupe

Answer 1

In Android, application versioning consists of two things.

1. android:versionCode - An integer value that represents the version of the application code, relative to other versions.
2. android:versionName — A string value that represents the release version of the application code, as it should be shown to users.

What is visible to the users is the second one . So you can have for example a version in alpha where android:versionName is "1.0.0" and android:versionCode is 1 (integer), then do your testing and fixes and when you are ready to deploy in production keep android:versionName to "1.0.0" but have android:versionCode increased by 1 from the last value it had in alpha, eg android:versionName="1.0.0" , android:versionCode=5 (the production is the 5th update from your initial aplha deploy). Of course you can change "1.0.0" to whatever you like, you can lower it too eg "0.9.0" , it's android:versionCode that always should be incremented by 1 .

Answer 2

Version codes need only to be unique. As per document system does not enforce that new apk should have a greater version code.

Though a device, having installed an apk with a higher version code (17 in your case) will neither get update notification from play store nor play store will show that an update is available, because apk has a lower version code (10 in your case). It does not matter that v10 is uploaded after v17.

Yes! Just yesterday I had versionCode 701 in the Alpha lane and wanted to publish a Beta from a different branch. The Alpha includes some features that are only available to our team, and the beta is a public Beta that doesn't have all the Alpha features merged in yet.

I hadn't used versionCode 700 yet, so I pushed that to the beta lane and it was accepted by the play store.

So, now, versionCode 700 is available for download to Beta testers, while versionCode 701 is in Alpha, and the Alpha version (701) was uploaded BEFORE the Beta version (700).

It seems like what matters is if the versionCode has been used yet. Hopefully that helps!
