錯誤字節碼轉換到DEX在真實設備whilte運行

Question

我歌林更新版本1.1.4-2然後我開始運行我的實際設備項目，但它顯示這個錯誤 - >

模塊：應用程序build.gradle文件我添加了上次的依賴目標兼容性，但它根本不工作。每當我跑在我的設備它上面顯示錯誤 - >

請告訴我如何解決這個問題。

Answer 1

錯誤清楚地告訴您在庫的子模塊中將target和source兼容性更改爲1.7。爲什麼不能改變這一點？

我認爲它可能要求您更改 此：

compileKotlin { 
kotlinOptions { 
    jvmTarget = "1.8" 
} 
} 
compileTestKotlin { 
kotlinOptions { 
    jvmTarget = "1.8" 
} 
} 

這樣：

compileKotlin { 
kotlinOptions { 
    jvmTarget = "1.7" 
} 
} 
compileTestKotlin { 
kotlinOptions { 
    jvmTarget = "1.7" 
} 
}
