Download specific fields of download/install stats from Google Play Developer Console
Google provides statistics on the number of downloads/installs/uninstalls for your Android apps, which you can view on Google Play Developer Console. They also allow you to export those numbers in a CSV file at a push of a button.
Sometimes though, you may want to select only some fields that you are interested in, and be able to specify a date range too. All of them are actually defined as query strings in the following URL format:
https://play.google.com/apps/publish/statistics/download?package=<your_app_package_name>&sd=<start_yyyymmdd>&ed=<end_yyyymmdd>&dim=overall&met=current_device_installs,daily_device_installs,daily_device_uninstalls,total_user_installs,daily_user_uninstalls
NOTE: Obviously, you need to be already logged in to access the information. Otherwise, you may wish to come up with a secure way to pass your login credentials, so that you can write a script to automate the process.
