This is regarding PSLab app update in Fdroid. We have recently created two flavors to support openstreet maps and Google maps. We use fdroid flavor with openstreet maps to publish in Fdroid. Once the flavors were added (in v2.0.17), Fdroid build failed for obvious reasons and I updated the metadata file. When I try to build it, it seems building successful, but fails eventually with the following error log.

Gradle may disable incremental compilation as the following annotation processors are not incremental: realm-annotations-processor-5.8.0.jar (io.realm:realm-annotations-processor:5.8.0), butterknife-compiler-8.8.1.jar (com.jakewharton:butterknife-compiler:8.8.1).
Consider setting the experimental feature flag android.enableSeparateAnnotationProcessing=true in the gradle.properties file to run annotation processing in a separate task and make compilation incremental.

Description: |-
Pocket Science Lab hardware device provides an array of sensors for doing
science and engineering experiments. It provides functions of numerous
experimental devices such as an oscilloscope, a waveform generator, a frequency
counter, a programmable voltage & current source and a data logger. This app
exposes all the functionalities of device along with using Audio Jack as
Oscilloscope and Wave Generator. The app has built-in support for experiments
covering areas like electronics, electrical and physics etc.

fdroid lint -v io.pslab doesn’t output anything either.
What could be the possible reason for “Wrong package ID”? 
I’ll close this thread now and update the merge request…
