I have an issue with my app that when I log in, the app crashes and I get the error:

java.lang.NoSuchMethodError: No static method metafactory(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite; in class Ljava/lang/invoke/LambdaMetafactory; or its super classes (declaration of 'java.lang.invoke.LambdaMetafactory' appears in /apex/com.android.runtime/javalib/core-oj.jar)

I have tried to mess with the gradle and change variables. The issue seems to stem from this package:

import retrofit2.Retrofit;
import retrofit2.converter.scalars.ScalarsConverterFactory;

public class RetrofitClient {
    private static Retrofit retrofit = null;

    public static Retrofit getClient(String baseURL)
    {
        if(retrofit == null)
        {
            retrofit = new Retrofit.Builder()
                         .baseUrl(baseURL)
                         .addConverterFactory(ScalarsConverterFactory.create())
                         .build();
        }
        return retrofit;
    }
}

It then gives to another reference to:

import com.example.usub.Remote.IGoogleAPI;
import com.example.usub.Remote.RetrofitClient;

public class Common {
    public static  final String baseURL = "https://maps.googleapis.com";

    public static IGoogleAPI getGoogleAPI()
    {
        return RetrofitClient.getClient(baseURL).create(IGoogleAPI.class);
    }
}

Here is my gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29
    defaultConfig {
        applicationId "com.example.usub"
        minSdkVersion 26
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.2.0-alpha01'
    implementation 'com.firebase:geofire-android:2.1.2'

    implementation 'com.google.android.gms:play-services-location:17.0.0'
}

apply plugin: 'com.google.gms.google-services'

How can I find the method to fix the error?

  • I had already added the Java 8 options in build.gradle and still had the issue. What worked for me is to move .addConverterFactory( ) before calling baseUri() – png Mar 09 '21 at 17:49

Try to switch to Java 8 compatibility mode, for proper de-sugaring of some library:

android {

    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

    kotlinOptions {
        jvmTarget = "1.8"
    }
}

Besides, Google JSON API might rather need the GsonConverterFactory.

    According to documentation https://square.github.io/okhttp/upgrading_to_okhttp_4/ it's also recommended to add android { kotlinOptions { jvmTarget = "1.8" } } – Mikhail Sharin Mar 20 '20 at 07:55

    @MikhailSharin This only applies when trans-piling from Kotlin to Java byte-code; so that's only required for Kotlin projects (or mixed projects), but it's not required for pure Java projects. Thanks for noticing, because I'm sure this may eventually help someone. – Martin Zeitler Apr 02 '20 at 17:11

    Man, I know that it's unprofessional but I Love You! I've been struggling with it for few hours now, and at first I didn't saw the compileOption in my gradle so I added it, and it works Perfect, Thank you! – Lidor Eliyahu Shelef Dec 13 '20 at 16:56
  • In my case, I was importing a new android library, my android library was compatible with java 8 but my main project wasn't. My solution was to make both compatible with java 8. – Luis Muñoz Aug 13 '21 at 21:42
  • I had to do a clean build after implementing these changes to get it working. – oziomajnr Sep 23 '21 at 17:08

You can resolve this error by setting compileOptions in build.gradle(app) file.

android {
    ...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

In my case, it was not for retrofit. I was using a local library module (named Android XML to PDF generator) that was using Java version 1.8 (for using Rx Java), but my app level Java version was less than 1.8.

So I simply added in the following lines in my app level build.gradle -

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

Then it worked for me!

Try to refactor the Retrofit dependencies.

Write this:

implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.squareup.retrofit2:converter-gson:2.2.0'

I just changed my dependencies to below and cleaned project. I was using latest version of retrofit library before but failed with same error. It worked for me.

implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-gson:2.3.0'
