我的 android 项目有一个我无法解决的错误。

我在一个 xml 中有一个游戏菜单布局：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RootView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/gamemenu_background"
    android:orientation="vertical" >

    <Button
        android:id="@+id/gaveup_button"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/gaveup_button">

    </Button>

    <Button
        android:id="@+id/choice_a_button"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/choice_a_button">   

    </Button>

    <Button
        android:id="@+id/choice_b_button"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/choice_b_button"/>

</RelativeLayout>

因此，对于每个按钮，我在可绘制文件夹中都有一个 xml 和一个图像：

选择a_button_xml.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/choice_a_button"></item>
</selector>

选择_b_button_xml.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:drawable="@drawable/choice_b_button"></item>
</selector>

在eclipse de layout的布局管理器中很好但是当我在虚拟设备上运行应用程序时出现错误并且应用程序无法启动：

那里发生了什么？此错误仅在具有大屏幕的虚拟设备中发生。

如果我将虚拟设备的最大 VM 应用程序堆大小设置为 48，则此应用程序有效。但这太多了..有什么方法可以让程序消耗更少的内存？

请帮我

我认为崩溃是由于以下内容造成的：

Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

您可能需要缩小图像。

@Michaeldcooney 说了什么，您还应该检查内存泄漏。此外，您的虚拟设备的 VM 内存大小（即应用程序可用的内存大小，而不是设备总内存大小）是多少？
