内存不足错误:Android Studio 上的 Java 堆内存

新手上路,请多包涵

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 后得到了这个。但是,我不认为这是问题所在。最有可能是在我开始将我的应用程序升级到 SDK 21 时(在此之前是 SDK 20)。但我也不太确定。

我在谷歌上搜索了 一些 修复 方法,但找不到有效的方法。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 大小。

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

没有什么变化。


编辑 2:

也做了 这个 修复,但也无能为力:

尝试以下操作:

Ctrl + Alt + S -> 编译器 -> Gradle

VM Options 字段中写入:

 -Xmx2048m -XX:MaxPermSize=512m

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

不过这个问题是由Google Play服务引起的,只需将其更改为特定库即可解决。

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

2022 年更新; DSL 元素 dexOptions ”已过时,应将其删除。它将在 Android Gradle 插件的 8.0 版本中被删除。

使用它没有任何效果,AndroidGradle 插件会自动优化 dexing。

我测试了 Gradle 7.0+ ,增加了下面提到的 org.gradle.jvmargs 选项是我们所需要的。

原始答案

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 打包会失败并 Java heap space 。在我的例子中,需要两件事来修复它。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
