Gradle Errors when building game for Android

My console error says this:
UnityEditor.BuildPlayerWindow+BuildMethodException: 3 errors
at UnityEditor.BuildPlayerWindow+DefaultBuildMethods.BuildPlayer (BuildPlayerOptions options) [0x0020e] in /home/builduser/buildslave/unity/build/Editor/Mono/BuildPlayerWindowBuildMethods.cs:181

at UnityEditor.BuildPlayerWindow.CallBuildMethods (Boolean askForBuildLocation, BuildOptions defaultBuildOptions) [0x00065] in /home/builduser/buildslave/unity/build/Editor/Mono/BuildPlayerWindowBuildMethods.cs:88

UnityEngine.GUIUtility: ProrocessEvent(Int32, IntPtr)

The crazy thing is the Android SDK can communicate with my cell phone. I can create applications with android SDK and push them out to my phone. But I can't get the Unity Remote to work with the unity on my Ubuntu computer neither can I get Unity to build an android game.
