build.gradle - All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes)

Just installed Android Studio for the first time on this new machine and was trying to import a project that used to work without any errors a year ago on another machine.
Had to fix plenty of errors by just downloading and installing updates (recommendations).
The one error that's left is in the title.
This is my build.gradle source:
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
repositories {
mavenCentral()
}
defaultConfig {
applicationId "com.test.testaa"
vectorDrawables.useSupportLibrary = true
minSdkVersion 19
targetSdkVersion 24
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})

Android API 26 Platform not found, package not available for download

This occurred after I upgraded my android studio. I've attempted all similar answers on stack overflow, and a few other obscure forums, but I'm not getting anywhere with this error and I've been at it for 6 hours. I've monkeyed around with the sdk tools manager as well, but I'm not getting anywhere. Oh, and that maven thing is new, tried it from a similar answer.
Here is my gradle file:
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "com.loredylore.lorebuilder"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {

use version 25.0.3, you may have to recast some views to text views when if you have to migrate backward from version 26 android to 25.

compile appcompat v7:26.+ error when adding play services for fusion location provider

I have an issue and have looked at possible duplicate questions and answers and I think this one is not answered by the others so asking it here.
I updated my play services to make use of the fused location provider and now the appcompat in my gradle is showing an error.
So I created a new project and checked the build.gradle on the new project and have exactly the same appcompat but my project is showing an error.
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "au.com.itmobilesupport.sqltwo"
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support:recyclerview-v7:26.+'
compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services-maps:11.0.0'
compile 'com.google.android.gms:play-services:11.0.1'
}
Its this line that is showing the error:
compile 'com.android.support:appcompat-v7:26.+'
But in a new project its fine. Why am I getting the error?
UPDATE:
If I remove these two lines then the error goes away:
compile 'com.google.android.gms:play-services-maps:11.0.0'
compile 'com.google.android.gms:play-services:11.0.1'
But I need them so still have the error.

Add these lines to your build.gradle file to get libraries that you don't have based on Google site.
allprojects {
repositories {
jcenter()
maven {
url "https://maven.google.com"
}
}
}
Caution: Using dynamic dependencies (for example, palette-v7:23.0.+) can cause unexpected version updates and regression incompatibilities. We recommend that you explicitly specify a library version (for example, palette-v7:25.4.0).

Finally solved the issue with the help of ZeroOne's answer to a similar question.
What led me to look at ZeroOnes answer was Google giving me the reason but not as an error. My issue was that the following line is too encompassing and a lot of extra dependencies were added that would have made the app unnecessarily larger.
compile 'com.google.android.gms:play-services:11.0.1'
I simply needed to be more specific and the error disappeared.
Here is the final gradle.
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "au.com.itmobilesupport.sqltwo"
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support:recyclerview-v7:26.+'
compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
testCompile 'junit:junit:4.12'
compile 'com.google.android.gms:play-services-maps:11.0.1'
compile 'com.google.android.gms:play-services-location:11.0.1'
}
And this is the specifc line I change the above to:
compile 'com.google.android.gms:play-services-location:11.0.1'
Hope it helps someone who comes across the same issue.

Being more specific using compile 'com.google.android.gms:play-services-location:11.0.1' rather than compile 'com.google.android.gms:play-services:11.0.1' saved my project as well, tks a lot guys.

}
apply plugin: 'com.google.gms.google-services'
This is the error I am getting:

You are using mismatching library versions. com.android.support:animated-vector-drawable is version 25.3.1 while your com.android.support:recyclerview-v7 is version 25.1.1. Using mismatched versions could cause your app to crash/errors. FirebaseUi must be using version 25.1.1.
Add the below to your apps gradle:
compile 'com.android.support:recyclerview-v7:25.3.1'

You can suppress the warnings on Android Studio.
Analyze > Inspect Code find the warning the you want to suppress and click it then Alt+Enter find suppress warning on the menu.
