Android工作室错误：任务执行失败：app：transformClassesWithDexForDebug

Question

我在 android studio 中遇到了这个错误

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: 

com.android.ide.common.process.ProcessException:java.util.concurrent.ExecutionException:com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException:

Process 'command 'C:\Program Files\Java\jdk1.8.0_66\bin\java.exe'' finished with non-zero exit value 1

build.gradle 文件是

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }

Answer 1

dexOptions {
    incremental true
    javaMaxHeapSize "4g"
}

将以上行放在 gradle 中的 android 括号中，并将以下行放在您的 LAUNCHER Activity 的 onCreate 开头。

    MultiDex.install(this);

然后从 Build -> Clean Project 中清除您的项目。

这会解决你的问题。
