Xamarin Forms Android .APK vs .AAB (Bundle)

Question

Xamarin Forms Android .APK vs .AAB (Bundle)

Ogero Ovie 1

I am having issues with a cross-platform Xamarin Forms app I created using Visual Studio 2019 and 2022. I use SQLite in the app.

Basically, when I set the property Android Package Format to apk and run the app on Android device or Emulator everything works fine.

But when I set the property Android Package Format to bundle (that produces .aab file), I get SQLite exception saying "Cannot Create Table Without Columns ... Does (Models.TableName) Contains Public Properties?"

I have tried different App properties for Android including Link Sdk and Users Assemblies with no luck.

Does anybody know why SQLite works in .apk package but not in bundle(.aab)?

Many thanks

BTW, all the columns in the table contains are set to public.

Hello,

Welcome to our Microsoft Q&A platform!

when you generate the .aab file, do you publish this aab file to the Google play store? Or you install it directly in your android device or emulator. For the aab file, you need to upload it the google play store then download and install your device.

And try to set the Linker to none, then make a test.

Best Regards,

Leon Lu

Many thanks Leon,

.AAB build cannot be installed on a device. To answer your question, I built the app with the property Android Package Format set to bundle (this produce .aab file). I then uploaded the .aab file to Google Play Store via a web browser. .AAB is the only format Google will accept. .APK can no longer be uploaded.

Google then process the app for download. When I download the resulting .APK from Google App store I get SQLite exception that saying "Cannot create table without columns. Does (Models.TableName) contains public properties?"

The table class is set to public, and all columns for the table are set to public too.

Setting the Linker to none was how I started.

There are lots of app on Google app store and I can assume that some of them will have be built using Xamarin Forms.

Please help.

Can you share code about creating table. if you create a table with _database.CreateTableAsync<Piece>().Wait();, if so, please remove the Wait() method.

Leon,

I owe you a great gratitude. You are right. I set the Linking to none and it worked. I uploaded it, downloaded the app and everything works fine now.

You are a genius and I appreciate your help beyond works can express.

Thank you very much.
