Execution failed for task ':app:compileDebugJavaWithJavac'. > Compilation failed

Hello guys this is the error which I faced while I was running the app. I am fresher to android so I cant get the results.I already gone through some tech websites it suggested to change versions (compile SDK version and Build tools version ) yet I cant solve this. Can any one help me to solve this ?.
Error Message :
Error:Execution failed for task ':app:compileDebugJavaWithJavac'.

Make sure android sdk localtion is set correctly
ANDROID_HOME = home/user/android_sdk/ "this is correct location"
ANDROID_HOME = home/user/android_sdk/tools "wrong path"
or
downgrade your gradle version

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:

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:

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.

Android NoClassDefFoundError after adding constraint layout

I've started getting java.lang.NoClassDefFoundError: for random class and that class changes on my every teammates machine and it's only happening for 5.x devices, we tested on 6.0 and 7.0 but everything is working fine there.
This started happening after adding 'com.android.support.constraint:constraint-layout:1.0.2'
We decide to start using constraint layout in app and since then we're getting this error

Update:
I've removed constraint layout from xml's and removed this line:
compile 'com.android.support.constraint:constraint-layout:1.0.2'
And now app is working fine.

Four reasons are generate NoClassDefFoundError in android:
1) The class is not available in Java Classpath.
2) You might be running your program using jar command and class was not defined in manifest file's ClassPath attribute.
3) Any start-up script is overriding Classpath environment variable.
4) Because NoClassDefFoundError is a subclass of java.lang.LinkageError it can also come if one of it dependency like native library may not available.
Before build apk clean your project.

Android studio build issue Google sign in and Firebase latest version 10.2.4

Android studio build issue Google sign in and Firebase latest version 10.2.4
google sign in was working fine until I have put firebase jar in gradle and its throwing "Error:(149, 28) The type com.google.android.gms.common.internal.safeparcel.AbstractSafeParcelable cannot be found in source files, imported jack libs or the classpath"

Looks like you skipped this step
apply plugin: 'com.google.gms.google-services' line be at the bottom of your app/build.gradle file
https://developers.google.com/android/guides/google-services-plugin
Sidenote: You have Glide and Picasso, two-way gif drawable libraries, and two shaped imageview libraries. Each pair do the same thing. Clean out your dependencies to reduce your app size and chances of errors

I had a similiar problem with firebase yesterday and this worked for me:
Just add this to gradle file and rebuild it:
android {
....
dexOptions {
// Prevent OutOfMemory with MultiDex during the build phase
javaMaxHeapSize "4g"
}
}
