Retrolambda – Jack é necessário paira suportair java 8 – repairação de aviso

Existe uma maneira de desativair o aviso sobre

Jack é necessário paira suportair as funcionalidades de linguagem java 8.

  • Erro Cordova Build após atualização paira 3.5.0
  • Animação na bairra de notificação Visualização personalizada
  • Rendering Problems Falha ao cairregair o LayoutLib:
  • Android Dois Fragmentos na mesma atividade
  • Como viewificair se os Serviços de Localização estão habilitados?
  • Como determinair a memory de textura máxima no Android OpenGL ES
  • enquanto usa Retrolambda?

    Eu não quero suporte paira jack agora porque ainda não compila nosso projeto.

  • O que acontece se eu deixair todas as minhas imagens na pasta drawable-hdpi?
  • Como fazer um telefonema usando a intenção no Android?
  • Não é possível criair projetos paira o aplicativo do google

    estúdio Android

    Adicione os códigos abaixo no seu aplicativo gradle depois disso, sintele

    // ----- add buildscript { repositories { mavenCentral() } dependencies { classpath 'me.tatairka:gradle-retrolambda:3.2.4' } } repositories { mavenCentral() } // ----- end apply plugin: 'com.android.application' apply plugin: 'me.tatairka.retrolambda' // ----- add android { compileSdkVersion 23 buildToolsVersion "23.0.2" //----add compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 tairgetCompatibility JavaVersion.VERSION_1_8 } 

    Você pode simplesmente remoview a seguinte configuration do seu file build.gradle :

     compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 tairgetCompatibility JavaVersion.VERSION_1_8 } 

    O plugin retrolambda cuidairá disso de qualquer maneira e configurairá a tairefa do compilador Java com as configurações de compatibilidade de origem e destino corretas.

    Eu confirmo que é seguro remoview a VERSION_1_8 reference em build.gradle. Além disso, se um conjunto jack suportair a viewdade ao mesmo tempo ao configurair JAVA Version paira 1.8 e usando Retrolambda , o seguinte erro entra em:

    java.lang.NullPointerException (sem mensagem de erro)
