now Im using Gradle 3.2.1 in local Please help me :(

Answer 1

Use gradle 3.1.2 , not 3.2.1 , unless you absolutely have to have 3.2.1 .

When I tried to build with gradle 3.2.1, it failed, saying this:

Could not find com.android.tools.build:gradle:3.2.1.

Answer 2

Looks like you're using a version of Gradle lower than 4.1. Change the distribution URL in your gradle-wrapper.properties as follows:

distributionUrl=https\\://services.gradle.org/distributions/gradle-4.8-all.zip

To locate the gradle-wrapper.properties file, press ctrl + shift + N in Android Studio and type gradle-wrapper

Change the dependencies as follows:

dependencies {
    classpath 'com.android.tools.build:gradle:3.1.3'

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

Answer 3

Currently Android studio 3.2 is not in stable state. Its in canary release state. So its gradle plugin is in alpha state

classpath 'com.android.tools.build:gradle:3.2.0-alpha17'

This version of gradle plugin is available in Android Studio 3.2 Canary17

If you want to use stable version then download Android Studio 3.1.3
