Android Studio 运行时异常：dex 写入线程中出现意外异常

androidandroid-studiogradleandroid-gradle-plugindex
21

我今天一整天都在遇到这个奇怪的错误 - 有人知道这里出了什么问题吗？

据我所知，我已经正确地使用了multidex库（以下是从app.gradle文件中获取的）：

defaultConfig {
    applicationId "com.example.simon"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    /*Enabling multidex*/
    multiDexEnabled true
}

dependencies {
    /*    Enabling multidex*/
    compile 'com.android.support:multidex:1.0.1'
}

我的顶层 gradle 文件非常基础:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.3.0'
        classpath 'com.google.gms:google-services:1.3.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

错误：

你尝试过使用--info或--debug运行以获取更多信息吗？如果没有其他办法，你可以尝试找到并手动运行gradle正在运行的确切命令，以查看其输出和失败原因。 - JesusFreke
嗨，我今天稍后会运行它并回复你 - 抱歉回复慢了。 - Simon

在谷歌搜索一段时间后，我发现问题是dex写入器分配的堆空间不够。

我通过在我的应用gradle.build中添加以下内容来解决它:

android {
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
    }
}

这个选项也成功地显著加速了我的 gradle 编译。

使用 Gradle（Android Studio）编译时间极长

细节：dexOptions {} 应该放在 build.gradle 的 android {} 块内。 - tarkeshwar

“incremental true”已被弃用，但“javaMaxHeapSize "4g"”非常好用！谢谢！ - sagus_helgy

将以下内容添加到我的项目级gradle.properties中有所帮助 -

org.gradle.jvmargs=-Xmx1536m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

将您的清单更改为以下内容。
defaultConfig 
{
    applicationId "com.example.simon"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
    /*Enabling multidex*/
    multiDexEnabled true
}
android {
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
    }
}

dependencies {
    /*    Enabling multidex*/
       compile 'com.android.support:multidex:1.0.1'
}

这个问题在添加“:”时出现。
/*Enabling multidex*/
    multiDexEnabled true

大多数情况下。如需更多信息，请告诉我您不理解的确切内容。
