Is there any way to increase Firebase Analytics upload rate for logged events on android? Currently it uploads them every hour and it is too slow for testing purposes.
No, the application can not control the upload cadence for Firebase Analytics. On Google Play devices the uploading is done by Google Play Services and there is no application code involved in the process. On non Google Play devices the uploading is done from the application process. Accelerated uploading is common request and and it might be supported in future release.
