Current portal design doesn't support multiple binaries per app management although it is possible to submit multiple binaries. Only the most recent submitted binary is visible. There are multiple families of devices supported and multiple target SDKs so this requires full support for multiple binaries. Check it out how Google does it on Google play dev Console. thanks
Hi Anatolyl, Yes, it is possible to upload multiple binaries for your app. As you update your existing app, when you reach the Binary File(s) tab, and have uploaded your first APK with selected targeting, click save and add another binary. Then, upload your second binary and select the second binary targeting. Click save and add another binary until you have the number of desired binaries and respective device targeting selected for each. Be sure to follow the versionName and versionCode requirements in your manifest.
