Question

我的android项目出错，我无法解决。

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，我有一个xml和一个文件夹drawable：

choice_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>

choice_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出现。

如果我将我的虚拟设备的最大VM应用程序堆大小设置为48，则此应用程序可以工作。但这太多了。有什么方法可以让程序占用更少的内存？

请帮帮我

Answer 1

我认为崩溃的原因在于：

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

您可能需要缩小图像。

Answer 2

@Michaeldcooney说什么，你也应该检查内存泄漏。此外，虚拟设备的VM内存大小（应用程序可用的内存大小，而不是设备总内存大小）是什么？
