java - 如何修复 minSdkVersion 21 中的 DEX 64K 方法限制？

Question

我在创建 APK 文件时遇到了这个错误:

Error:The number of method references in a .dex file cannot exceed 64K. Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html

我引用了这个tutorial解决这个问题，但我仍然收到这个错误。

我在我的项目中使用了 MultiDex，如下所示:

在用于 sdk 16 的 biuld.gradle 中:

apply plugin: 'com.android.application'

repositories {
    jcenter()
    mavenCentral()
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "com.saly.test"

        minSdkVersion 16
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"

        multiDexEnabled true

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile project(':volley')
    compile 'com.android.support:multidex:1.0.1'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'
    compile 'com.android.support:recyclerview-v7:24.0.0'
    compile 'com.android.support:cardview-v7:24.0.0'
    compile 'com.android.support:support-v4:24.0.0'
    compile 'com.google.android.gms:play-services:9.2.1'
    compile 'com.google.android.gms:play-services-location:9.2.1'
    compile 'com.google.android.gms:play-services-gcm:9.2.1'
    compile 'com.google.android.gms:play-services-maps:9.2.1'
    compile 'com.onesignal:OneSignal:2.+@aar'
}

在 sdk 16 的 list 中:

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...>

    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">

        ...

    </application>
   </manifest>

现在我得到了新的错误:

Error:UNEXPECTED TOP-LEVEL ERROR: Error:java.lang.OutOfMemoryError: GC overhead limit exceeded Error: at com.android.dx.cf.cst.ConstantPoolParser.parse0(ConstantPoolParser.java:289) Error: at com.android.dx.cf.cst.ConstantPoolParser.parse(ConstantPoolParser.java:150) Error: at com.android.dx.cf.cst.ConstantPoolParser.parseIfNecessary(ConstantPoolParser.java:124) Error: at com.android.dx.cf.cst.ConstantPoolParser.getPool(ConstantPoolParser.java:115) Error: at com.android.dx.cf.direct.DirectClassFile.parse0(DirectClassFile.java:491) Error: at com.android.dx.cf.direct.DirectClassFile.parse(DirectClassFile.java:406) Error: at com.android.dx.cf.direct.DirectClassFile.parseToInterfacesIfNecessary(DirectClassFile.java:388) Error: at com.android.dx.cf.direct.DirectClassFile.getMagic(DirectClassFile.java:251) Error: at com.android.dx.command.dexer.Main.parseClass(Main.java:772) Error: at com.android.dx.command.dexer.Main.access$1500(Main.java:85) Error: at com.android.dx.command.dexer.Main$ClassParserTask.call(Main.java:1700) Error: at com.android.dx.command.dexer.Main.processClass(Main.java:755) Error: at com.android.dx.command.dexer.Main.processFileBytes(Main.java:723) Error: at com.android.dx.command.dexer.Main.access$1200(Main.java:85) Error: at com.android.dx.command.dexer.Main$FileBytesConsumer.processFileBytes(Main.java:1653) Error: at com.android.dx.cf.direct.ClassPathOpener.processArchive(ClassPathOpener.java:284) Error: at com.android.dx.cf.direct.ClassPathOpener.processOne(ClassPathOpener.java:166) Error: at com.android.dx.cf.direct.ClassPathOpener.process(ClassPathOpener.java:144) Error: at com.android.dx.command.dexer.Main.processOne(Main.java:677) Error: at com.android.dx.command.dexer.Main.processAllFiles(Main.java:569) Error: at com.android.dx.command.dexer.Main.runMultiDex(Main.java:366) Error: at com.android.dx.command.dexer.Main.run(Main.java:275) Error: at com.android.dx.command.dexer.Main.main(Main.java:245) Error: at com.android.dx.command.Main.main(Main.java:106) :app:transformClassesWithDexForDebug FAILED 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 3

然后我将我的最小 sdk 更改为 21 以修复此错误，但它不起作用。

这是我的 build.gradle for sdk 21:

apply plugin: 'com.android.application'

repositories {
    jcenter()
    mavenCentral()
}

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "com.saly.test" 

        minSdkVersion 21
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    productFlavors {
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile project(':volley')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'
    compile 'com.android.support:recyclerview-v7:24.0.0'
    compile 'com.android.support:cardview-v7:24.0.0'
    compile 'com.android.support:support-v4:24.0.0'
    compile 'com.google.android.gms:play-services:9.2.1'
    compile 'com.google.android.gms:play-services-location:9.2.1'
    compile 'com.google.android.gms:play-services-gcm:9.2.1'
    compile 'com.google.android.gms:play-services-maps:9.2.1'
}

我该如何修复这个错误？

提前致谢。

只需添加这些行

dexOptions {
    javaMaxHeapSize "4g"
}

在你的gradle脚本里面的任何地方

android { 
....

dexOptions {
    javaMaxHeapSize "4g"
}

....
}
