我不知道这是否仍然相关，但只是想分享对我有用的东西。

做完了。

通过设置这个选项，稍微增加堆的大小

运行→运行配置→参数→虚拟机参数

-Xms1024M -Xmx2048M

Xms—用于最小限制

Xmx -表示最大限制

如果您确定程序中没有内存泄漏，请尝试:

增加堆的大小，例如-Xmx1g。 启用并发低暂停收集器-XX:+UseConcMarkSweepGC。 在可能的情况下重用现有对象以节省内存。

如果需要，可以通过在命令行中添加-XX:-UseGCOverheadLimit选项来禁用限制检查。

在Netbeans中，设计最大堆大小可能会有所帮助。执行命令Run =>设置项目配置=>自定义。在弹出窗口的运行中，进入虚拟机选项，填写-Xms2048m -Xmx2048m。它可以解决堆大小的问题。

试试这个

打开构建。gradle文件

  android {
        dexOptions {
           javaMaxHeapSize = "4g"
        }
   }

I'm working in Android Studio and encountered this error when trying to generate a signed APK for release. I was able to build and test a debug APK with no problem, but as soon as I wanted to build a release APK, the build process would run for minutes on end and then finally terminate with the "Error java.lang.OutOfMemoryError: GC overhead limit exceeded". I increased the heap sizes for both the VM and the Android DEX compiler, but the problem persisted. Finally, after many hours and mugs of coffee it turned out that the problem was in my app-level 'build.gradle' file - I had the 'minifyEnabled' parameter for the release build type set to 'false', consequently running Proguard stuffs on code that hasn't been through the code-shrinking' process (see https://developer.android.com/studio/build/shrink-code.html). I changed the 'minifyEnabled' parameter to 'true' and the release build executed like a dream :)

简而言之，我必须改变应用程序级别的“构建”。Gradle文件来自: / /……

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.sign_config_release
    }
    debug {
        debuggable true
        signingConfig signingConfigs.sign_config_debug
    }
}
