Local reproduction

Can it be reproduced on your own Mac/PC by following our local debug guide? Please follow at least the first section (“Testing with a full clean git clone”) to make sure to test the state of the code what bitrise.io will get when it does a git clone in the clean environment! If possible please note which sections you tried.

Clean git, local build is successful.

Local reproduction: Linux / Android (docker based) stack builds

Can it be reproduced by running the build locally, after doing a new git clone of the repository into the /tmp directory and running the build from there with the Bitrise CLI ( Bitrise CLI )? If no, can it be reproduced with Docker (using the same docker images / environment we use on bitrise.io)? Related guide: Redirecting… .

We have resolved this issue by explicitly including the installreferrer AAR in our project.

Download the AAR from Maven: https://mvnrepository.com/artifact/com.android.installreferrer/installreferrer

Copy the AAR file into your Droid project somewhere, e.g. a lib/ directory in the project root.

Then, in the Droid csproj:

<ItemGroup>
  <Folder Include="lib\" />
</ItemGroup>
<ItemGroup>
  <AndroidAarLibrary Include="lib\installreferrer-1.1.2.aar" />
</ItemGroup>
