My app worked fine but after running it a few times I got a problem with the gradle build. (Android Studio: failed to complete gradle execution, cause is empty) i've restarted my computer and before trying to fix the issue it showed me that I have an update for a few thing in android studio. After the update it asked me to update some versions of implementation in the gradle and then the "com.google.gms:google-services" version in the project gradle. After doing so I get an error saying "IDE error occured" when trying to do a build. The exception is occuring in the Android Support Plugin.

The exception details:

null

Project gradle:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.2.1' // google-services plugin


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }

        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Module gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'
    defaultConfig {
        applicationId 'com.example.elaymac.randochat'

            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

I solved the problem thanks to Severiano Jaramillo Quintanar's answer!

I faced the exact same problem, I was afraid I broke something... I fixed it by cleaning and rebuilding the project (I had disabled instant run as suggested here before but I guess that was not necessary as I enabled it again after cleaning and rebuilding the project and worked just fine...).

Build -> Clean Project

Build -> Rebuild Project

I am not sure if rebuilding would be necessary, I did both steps and it worked fine, maybe just cleaning the project would have been sufficient.

Hope that helps!!

EDIT

Nice, one more thing. When I solved the problem depicted here I found another problem, when I clicked run the apk was not being created and I solved it with my answer on that other thread:

The APK file does not exist on disk

In Android Studio:

  1. Go to File / Invalidate caches.. /
  2. Then select both options and restart
  3. After restarting of Android Studio your problem is solved out
