You need to either be an Android Device Retailer (selling smartphones / tablets / Android TV boxes) or you need to be an Android developer. The people that make the most money combine their devices with some form of development.
That’s where we come in. We have produced popular Android products in the 2 biggest growth sectors of Android. All you do is send in your company details and we make the app yours. That’s it. Then you can install your software on the devices you sell or you can distribute online or on the Play Store.
