Unable to install APK to device

I want to build my game, to see how it works on my phone. I tried so often to build with other player settings, but it my phone doesnt want to install my game. Unity has the correct SDK path and USB-Debugging is enabled on my phone. If I build and run, this comes out:

CommandInvokationFailure: Unable to install APK to device. Please make sure the Android SDK is installed and is properly configured in the Editor. See the Console for more details.
