New Unity Build problem MAC (URI scheme must start with a letter ...)

Please help!
I am trying to build APK for a game (Android) I have. I've tried both Build, and Build and Run, none works for me.
When I use "Build" I get these 2 problems. The first problem is that it says build succeeded while it doesn't/there isn't any build/APK. The second problem is, well, I don't know much about it. It's down below.
1. Build completed with a result of 'Succeeded' UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)
Although it says build completed with a result of Succeeded, it's wrong. I mean there is NO build at all. There is no APK in the folder which it builds. I've tried changing the folder, it still doesn't work.
2. UriFormatException: URI scheme must start with a letter and must consist of one of alphabet, digits, '+', '-' or '.' character.... System.Uri.Parse (UriKind kind, System.String uriString) System.Uri.ParseUri (UriKind kind) System.Uri..ctor (System.String uriString, Boolean dontEscape) System.Uri..ctor (System.String uriString) System.Xml.XmlResolver.ResolveUri (System.Uri baseUri, System.String relativeUri) System.Xml.XmlUrlResolver.ResolveUri (System.Uri baseUri, System.String relativeUri) Mono.Xml2.XmlTextReader.GetStreamFromUrl (System.String url, System.String& absoluteUriString) Mono.Xml2.XmlTextReader..ctor (System.String url, System.Xml.XmlNameTable nt) System.Xml.XmlTextReader..ctor (System.String url, System.Xml.XmlNameTable nt) System.Xml.XmlTextReader..ctor (System.String url) UnityEditor.AndroidXmlDocument..ctor (System.String path) UnityEditor.Android.PostProcessor.Tasks.PrepareAPKResources.PatchStringsXml () UnityEditor.Android.PostProcessor.Tasks.PrepareAPKResources.Execute (UnityEditor.Android.PostProcessor.PostProcessorContext context) UnityEditor.Android.PostProcessor.PostProcessRunner.RunAllTasks (UnityEditor.Android.PostProcessor.PostProcessorContext context) UnityEditor.Android.PostProcessAndroidPlayer.PostProcess (BuildTarget target, System.String stagingAreaData, System.String stagingArea, System.String playerPackage, System.String installPath, System.String companyName, System.String productName, BuildOptions options, UnityEditor.RuntimeClassRegistry usedClassRegistry, UnityEditor.Build.Reporting.BuildReport report) UnityEditor.Android.AndroidBuildPostprocessor.PostProcess (BuildPostProcessArgs args, UnityEditor.BuildProperties& outProperties) UnityEditor.PostprocessBuildPlayer.Postprocess (BuildTargetGroup targetGroup, BuildTarget target, System.String installPath, System.String companyName, System.String productName, Int32 width, Int32 height, BuildOptions options, UnityEditor.RuntimeClassRegistry usedClassRegistry, UnityEditor.Build.Reporting.BuildReport report) (at /Users/builduser/buildslave/unity/build/Editor/Mono/BuildPipeline/PostprocessBuildPlayer.cs:285) UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)**

However,
when I use "Build and Run", I get below 4 errors.
