内存不足错误：Android Studio 上的 Java 堆内存

编译安卓项目时如何修复？java.lang.OutOfMemoryError: Java heap space

我在升级到Android Studio的版本1后得到了这个。但是，我不认为这是问题所在。最有可能的是当我开始将我的应用程序升级到SDK 21时（在此之前是SDK 20）。但我也不是那么确定。

我已经在谷歌上搜索了一些修复程序，但找不到一个有效的修复程序。大多数修复程序都是针对 Eclipse IDE 的。

这是我在编译时收到的完整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罐子库（zip4j）吗？我确实尝试删除它，但仍然发生OOM错误。任何想法如何解决这个问题？

编辑：

我还编辑了 gradlew 文件以增加 -Xmx 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：

也做了这个修复，但也忍不住：

请尝试以下操作：

Ctrl + Alt + S-> 编译器 -> Gradle

在字段写入中：VM Options

-Xmx2048m -XX:MaxPermSize=512m

答案 1

更新2022;DSL 元素“dexOptions”已过时，应将其删除。它将在 Android Gradle 插件的 8.0 版中删除。
使用它没有任何效果，AndroidGradle插件会自动优化dexing。

我测试了，使用Gradle ，在下面提到的选项增加是我们所需要的。7.0+org.gradle.jvmargs

原始答案

我在Android Studio 2.3.3上遇到了类似的问题。APK打包在从Android Studio构建并尝试处理300MB .so库时会失败。在我的情况下，需要两件事来修复它。你应该包含这样的东西：Java heap spacebuild.gradle

android {
    dexOptions {
        javaMaxHeapSize "4G"
    }
}

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

# 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

答案 2

这是旧的，但只需将其添加到构建文件中

dexOptions {
    javaMaxHeapSize "2g"
}
