This is the Class that have error

public static final String herokuLink = "https://mongodev.herokuapp.com/api/";

private static Retrofit getRetrofit(){
    return new Retrofit.Builder()
            .baseUrl(herokuLink)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
}

This method have interface class.

public static routerHeroku getService(){
    return getRetrofit().create(routerHeroku.class);
}

This error caused by atempt to use java 8 features witout adding it to project, as since version 2.7.0 Retrofit require java 8. So try to add this to your module-level build.gradle

  android {
    compileOptions {
        targetCompatibility = "8"
        sourceCompatibility = "8"
    }
}
