Wiko

We are using Java mostly to develop Android Apps and customise some part of the AOSP. Currently Kotlin is not pushed by Google for device manufacturer development, that why today ours apps are exclusively developed with Java language.

Python is a great language to develop tests automation. At Wiko we had develop a homemade solution to tests each software release. The tool check if requirements are well implemented, if there is no security issues (included user privacy). This tool use adb driver to communicate with tested Smartphone via USB.

We use Google Datastudio because with this reporting tool it's so easy to create reports from Firebase Analytics. You simply need to export your data analytics from Firebase to BigQuery, and then connect Google BigQuery to your Google Data Studio.
