在Android Studio中运行我的代码时出错

当我尝试在Android studio中运行代码时，我会遇到很多错误

错误，如“要在进程中运行dex，Gradle守护程序需要更大的堆。它当前大约有247 MB。要更快地生成，请将Gradle守护程序的最大堆大小增加到2048 MB以上。”

其他错误如“错误：拾取的JAVA选项：-Xmx256M”和“错误：未捕获的转换错误：JAVA.util.concurrent.ExecutionException:JAVA.lang.OutOfMemoryError:超出GC开销限制”

我可以知道我的项目出了什么问题吗？谁能帮我一下吗(

这是来自我的android studio消息选项卡的消息

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 247 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
For more information see https://docs.gradle.org/current/userguide/build_environment.html

这可能是因为项目中的gradle.properties中未设置内存量。请转到根项目目录，找到此文件并添加此行：

org.gradle.jvmargs=-Xmx4536m

这是我认为的最大金额。通常设置为1536

打开android studio，转到文件/其他设置/默认设置

在搜索“heap”之后，您可以找到最大堆大小并对其进行更改

如果上述解决方案无效，请尝试以下方法：

另一个解决方案可以是编辑build.gradle（模块）文件并添加以下行：

android {
....

dexOptions {
    javaMaxHeapSize "2g"
}

...

}

可能重复：另外：@Kuffs谢谢，但它对我不起作用..在

gradle.properties

文件中，只需注释这一行

#org.gradle.jvmargs=-Xmx1536m

它对我不起作用。我试过了，但问题仍然是一样的。你确定编辑了正确的文件吗？它应该在文件的第一行有一些内容比如“#项目范围的渐变设置”。还要确保首先执行clean Project。我找到了它，并将堆大小更改为2000。但它仍然不起作用。
