Unsupported method: BaseConfig.getApplicationIdSuffix()

First, open your application module build.gradle file.

Check the classpath according to your project dependency. If not change the version of this classpath.

from:

classpath 'com.android.tools.build:gradle:1.0.0'

To:

classpath 'com.android.tools.build:gradle:2.3.2'

or higher version according to your gradle of android studio.

If its still problem, then change buildToolsVersion:

From:

buildToolsVersion '21.0.0'

To:

buildToolsVersion '25.0.0'

then hit 'Try again' and gradle will automatically sync. This will solve it.

Alright I figured out how to fix this issue.

• Open build.gradle and change the gradle version to the recommended version:
  classpath 'com.android.tools.build:gradle:1.3.0' to
  classpath 'com.android.tools.build:gradle:2.3.2'
• Hit 'Try Again'
• In the messages box it'll say 'Fix Gradle Wrapper and re-import project' Click that, since the minimum gradle version is 3.3
• A new error will popup and say The SDK Build Tools revision (23.0.1) is too low for project ':app'. Minimum required is 25.0.0 - Hit Update Build Tools version and sync project
• A window may popup that says Android Gradle Plugin Update recommended, just update from there.

Now the project should be runnable now on any of your android virtual devices.

For Android Studio 3 I need to update two files to fix the error:--

1. app/build.gradle

buildscript {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

2. app/gradle/wrapper/gradle-wrapper.properties
