编译我的 android 项目时如何修复 java.lang.OutOfMemoryError: Java heap space

我在升级到 Android Studio 版本 1 后得到这个。但是,我不认为这是问题所在。最有可能在我开始将我的应用程序升级到 SDK 21 时(之前是 SDK 20)。但我也不太确定。

我用谷歌搜索了somefix,但找不到合适的。大多数修复都是针对 Eclipse IDE 的。

这是我在编译时得到的完整 logcat 错误:

warning: Ignoring InnerClasses attribute for an anonymous inner class
(net.lingala.zip4j.unzip.Unzip$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

是因为我使用了一个 jar 库(zip4j)吗?我确实尝试将其删除,但仍然出现 OOM 错误。知道如何解决这个问题吗?

编辑:

我还编辑了 gradlew 文件以增加 -Xmx 的大小。

GRADLE_OPTS="$GRADLE_OPTS \"-Xdock:name=$APP_NAME\" \"-Xdock:icon=$APP_HOME/media/gradle.icns\" \"-Xmx2048M \"-XX:MaxPermSize=512M\" \"-XX:ReservedCodeCacheSize=512M\""

没有任何变化。

编辑 2:

this 也进行了修复,但也无能为力:

尝试以下方法:

Ctrl + Alt + S -> 编译器 -> Gradle

VM Options字段写入:

-Xmx2048m -XX:MaxPermSize=512m

【问题讨论】:

检查堆转储...你也可以添加 android:largeHeap="true" @Prachi 没有任何帮助。我什至无法编译和运行它,我想如何检查堆转储? 已编辑。添加了我在 gradlew 文件中所做的修复。 我试过这个Solution,它对我有用。 如果有人遇到此问题并且在 Mac 上使用 AS 3.5+,您可以尝试this GitHub 解决方案。在关于 SO 的众多不同答案中,这对我有用(以及许多其他人的评论反应)。 【参考方案1】:

您更改了错误的参数,您应该将 -XX:MaxPermSize=512M 的大小增加到 -XX:MaxPermSize=2048M 左右:) 因为 android 模拟器使用大量 RAM。

【讨论】:

同样的错误 :( 我应该向 maxperm 添加更多内存吗? 是的,这样做,看看会发生什么 :) 顺便说一句:你的机器上有多少 RAM? 这是不正确的,XX:MaxPermSize是用来存储“虚拟机描述对象所需的数据,这些对象在Java语言级别不具备等价性。例如描述类和方法的对象是存储在永久代中。” (oracle.com/technetwork/java/javase/gc-tuning-6-140523.html) 我几乎想不出任何场景,AimanB 的代码和 Android Studio 需要超过 512MB 的 RAM 来存储类(not 对象)和方法。问题出在其他地方 你说得有道理。也许现在最好的办法是用 jvisualVM 创建一个转储(它在你 jdk 的 bin 文件夹中),然后用 MAT 分析它,它是免费的,更适合分析转储。 在你启动模拟器之前启动jvisualVM,你可以在jvisualVM的窗口左侧看到活动进程,然后启动模拟器,你会在JVM中看到模拟器的进程并打开监控选项卡,您将看到将为该进程分配多少堆。在您的 java android 进程崩溃后,使用 JVM 创建一个转储,然后使用 MAT 打开该转储并调查所有泄漏。【参考方案2】:

我终于通过在 gradle 依赖中限制 Google Play 服务解决了这个问题。

不过问题是由 Google Play 服务引起的,只需将其更改为特定的库即可解决。

 com.google.android.gms:play-services-base:6.5.87

更新

【参考方案3】:

这是旧的,但只需将其添加到构建文件中

dexOptions 
    javaMaxHeapSize "2g"

【讨论】:

格雷姆谢谢! 'gradle.properties' 中的参数由于未知原因总是被忽略。这很有帮助! 如果从命令行使用dx,你需要传递标志-JXmx2gdx -JXmx2g --dex ... 修改为“4g”,内存不足的错误时有发生。【参考方案4】:

以上答案适用于 gradle 构建(或通用 -Xmx)。如果有人来这里是为了一个非 gradle 项目,我通过在 android studio 设置中增加 DEX 的最大堆大小来解决这个问题 => 构建、执行、部署 => 编译器 => Android 编译器

【讨论】:

我在 File -> other Settings -> Default Settings -> Build, Execution, Deployment -> Compiler -> Android Compilers 中找到了这个配置【参考方案5】:

在项目的 gradle.properties 文件中为 Gradle 分配更多内存。例如:

org.gradle.jvmargs=-Xmx1024m

【讨论】:

重申一下,这需要放在gradle.properties 文件中,而不是build.gradle【参考方案6】:

我使用的是 Windows 操作系统。我通过将 _JAVA_OPTIONS 更新为 '-Xmx1024m' 解决了这个问题

    Win + X,选择系统 选择“高级系统设置” 选择“环境变量” 创建/编辑名为“_JAVA_OPTIONS”的变量 将变量值更新为 -Xmx1024m

【讨论】:

解决了我的问题。 bundletool 报告内存错误 +1。【参考方案7】:

我在 Android Studio 2.3.3 上遇到了类似的问题。当从 Android Studio 构建并尝试处理 300MB .so 库时,APK 打包会失败说 Java heap space。在我的情况下,需要两件事来解决它。您的 build.gradle 应该包含类似的内容:

android 
    dexOptions 
        javaMaxHeapSize "4G"
    

在项目的根目录下,您需要有一个名为 gradle.properties 的文件,其中包含以下内容:

# That's needed for java to be able the create the APK with our 300MB native  library
# Basically we grant java a 4GB heap.
org.gradle.jvmargs=-Xmx4608m

【讨论】:

重要的是不要错过答案的第二部分;)【参考方案8】:

构建 => 清理项目

然后

构建 => 重建项目

当我这样做时,它总是为我解决问题。

【讨论】:

我在很多问题中都看到了这个建议,而且重建确实可以解决大部分问题。困扰我的是为什么我们必须先清洁?重建不是自动清理吗?【参考方案9】:

这就是我所做的:

第一步:在您的应用程序中,转到 GRADLE SCRIPTS -> GRADLE.PROPERTIES -> 将 org.gradle.jvmargs=-Xmxm 更改为 org.gradle.jvmargs=-Xmx4G

第二步:在您的应用程序中,转到 GRADLE SCRIPTS -> build.gradle -> 在 安卓

//添加这一行:

dexOptions 
   javaMaxHeapSize = "4G"
   

【讨论】:

【参考方案10】:

使用 Proguard 的调试版本也可能会出现此问题。要解决它,请将 minifyEnabledshrinkResources 更改为 false。

android 
...
buildTypes 
    release 
        minifyEnabled true
        shrinkResources true
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    

    debug 
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    
   

【讨论】:

【参考方案11】:

只需将其添加到 gradle 文件中:

android
testOptions 
        ....
        unitTests.all 
            jvmArgs "-Xmx2g" // to avoid outOfMemory exception
        
        ....
    

【讨论】:

【参考方案12】:

没有一个答案对我有用,但最后我发现了一些对我有用的东西:

自动管理分页文件大小

在窗口中:

    在“高级系统设置”下 高级选项卡 性能部分,设置... 高级选项卡 虚拟内存...更改... 选择自动管理所有驱动器的分页文件大小

我不记得为什么我没有选中它,但这在我的 gradle 构建中造成了麻烦(有颤动)。

【讨论】:

【参考方案13】:

在项目的根目录中打开 gradle.properties 文件

注释掉: # org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

是的!只需删除行前的# 哈哈哈哈!

【讨论】:

【参考方案14】:

您可以使用 Android Studio 中的 UI 来完成此操作,with friendly defaults

【讨论】:

【参考方案15】:

关闭模拟器,然后编译。默认不允许我同时使用两者

【讨论】:

【参考方案16】:

只需将其添加到您的 gradle.properties 文件中,即可避免此错误。

但仔细研究每一行。

【讨论】:

【参考方案17】:

经过大量研究,我找到了这个解决方案,我也遇到了同样的问题。 你可以通过改变这个来解决这个问题。转到 gradle.properties 并更改

org.gradle.jvmargs=-Xmx500m

org.gradle.jvmargs=-Xmx2048m
