How to Set -Source 1.7 in Android Studio and Gradle

Gradle version 1.8 is required. Current version is 1.6

I am not sure if this will help you but here is what fixed it for me:

Open up this file in your project:

<Project>/gradle/wrapper/gradle-wrapper.properties

Edit the distributionUrl line and set it too:

distributionUrl=https\://services.gradle.org/distributions/gradle-1.8-all.zip

Rebuild your project.

Update: You might want to use gradle-2.8-all.zip now.

Android studio compile takes forever

Try set org.gradle.jvmargs setting in gradle.properties like the following:

org.gradle.jvmargs=-Xmx3g

Please pay attention that the first build of a big project after cleanup can take up to 10 mins or even a little more.

Some other tips:

update Android Gradle Plugin to the latest stable version (currently 7.1.3) and Gradle Version (currently 7.2). Refer to this document.
update Kotlin version to 1.6.10 or later.
update Android Studio and Build-Tools.

use JavaVersion.VERSION_11 for sourceCompatibility and targetCompatibility:

compileOptions {
   sourceCompatibility JavaVersion.VERSION_11
   targetCompatibility JavaVersion.VERSION_11
}

kotlinOptions {
    jvmTarget = "11"
    ...
}

set android.enableJetifier=false in grade.properties.

Using Android Studio with Java 1.7

I went to Java SE Downloads and downloaded Java 7 again. The method mentioned above worked for Eclipse.

Running the installer from this manual download placed the JDK in /Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home, which was accepted by Android Studio.

Gradle version 1.6 is required. Current version is 1.8-20130730220035+0000

I managed to fix my project through some combination of invalidating Android Studio cache, deleting .idea and .gradle directories and .iml files, restarting Studio, and reimporting the project:

Invalidate Cache confirm

on Mac OSX using Homebrew, brew install gradle then pick local gradle distribution and point to /usr/local/Cellar/gradle/1.7/libexec for gradle home:

Gradle sync failed in android studio 3.6

Please update the class path to latest version and check

dependencies {
        classpath 'com.android.tools.build:gradle:2.2.3'
    }

buildscript {
    repositories {
        google()       //add here
        jcenter()
        maven { url "https://jitpack.io" }

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.2'
    }
}

allprojects {
    repositories {
        google()      //and here also
        jcenter()
        maven { url "https://jitpack.io" }

    }
}

Latest Android Studio - Problem adding Google Service Gradle plugin to build.gradle file

paste code for your build-script class file in project-level gradle.build file, here is an example :

    /**
     * project-level - build.gradle file -- make sure buildscript is before 
     * plugins
    **/
    buildscript {
        repositories {
            mavenCentral()
        }
        dependencies {
// your classpath
            classpath 'com.google.dagger:hilt-android-gradle-plugin:2.41'
        }
    }
    
    // Top-level build file where you can add configuration options common to all sub-projects/modules.
    plugins {
        id 'com.android.application' version '7.1.3' apply false
        id 'com.android.library' version '7.1.3' apply false
