this is my build.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:3.4.2' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } ``` } allprojects { repositories { google() jcenter() ``` } ``` } task clean(type: Delete) { delete rootProject.buildDir } this is my logs: - Exception is: org.gradle.api.tasks.TaskExecutionException: Execution failed for task

Please degrade gradle to 3.3.2, I had degrade to 3.3.2 then its working. But it is not the right solution. ---

Hi there, i already solve my problem by downgrade the firebase. My problem occur because of the firebase library. //The firebase the one that has problem implementation ‘com.google.firebase:firebase-core:17.0.1’ implementation ‘com.google.firebase:firebase-database:18.0.0’ implementation ‘com.google.firebase:firebase-messaging:17.3.4’ implementation ‘com.firebaseui:firebase-ui-database:1.2.0’ //I have downgrade it to this version implementation ‘com.firebaseui:firebase-ui-database:1.2.0’ implementation ‘com.google.firebase:firebase-messaging:17.3.4’ implementation ‘com.google.firebase:firebase-auth:16.0.5’ implementation ‘com.google.firebase:firebase-database:16.0.4’ implementation ‘com.google.firebase:firebase-storage:16.0.4’ I’m not sure either this one can help you guys or not. I’m still new in programming world. ---
