Android 无法启动活动java.lang.RuntimeException

我的android应用程序由于某种原因无法启动该活动，该活动的名称是Caperucita，但我看不出问题所在，还有一个类似的活动运行perfecty，它是Ricitos。也许你能帮我

logcat中的错误：

看起来你的背景文件太大了。尝试删除下面相对布局中的背景属性，然后查看是否出现崩溃

 <RelativeLayout
    android:id="@+id/rootRL"
    android:layout_width="match_parent"
    android:layout_height="262dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:layout_weight="0.83"
    android:background="@drawable/caperucita_roja"
    android:orientation="vertical" >

要解决这个问题，您需要更多的内存，或者需要更少的内存。获取更多内存实际上是不可能的，但可以指定更大的堆大小。在清单中，使用largeHeap属性：

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:largeHeap="true" >

要减少所需的内存量，需要减小背景图像的大小。我会考虑缩小图像的大小。如果无法减小尺寸，请使用类似的程序优化图像，这样可以帮助减小文件大小而不影响图像质量
 您需要减少图形文件对内存的影响。从堆栈跟踪可以清楚地看出，系统在加载
caperucita_roja
背景时内存不足。（该文件的大小为480x3969，特别大。未压缩的内存将占用超过7MB。在许多设备上，这相当于应用程序可用总内存的一小部分。）请记住，Android设备的可用内存非常有限

这篇培训文章提供了一些有助于实现这一点的策略。
你能给我们展示一下你活动中的布局文件吗？我刚刚发布了它@RenatoLochettiCan你能发布Caperucita.java吗？这就是人@这就是问题所在，但是为什么它在Caperucita.java中不起作用，而在Ricitos.java中却起作用呢@Flynn81@Whady-背景图形文件有多大？问题是，系统在加载Caperucita.java中的这个layout.480x3969和ricitos.java@TedHoppKeep中的480x2461时内存不足。请记住，如果您的第一个活动在后台，而第二个活动在前台，那么为第一个活动的可绘制部分分配的内存将不会被垃圾收集。因此，即使加载一次，第二次加载图像似乎会使你的应用程序崩溃。@Whady我用两条建议更新了答案。当然可以尝试使用largeHeap属性，在遇到内存不足异常时，我在这方面运气不错。
