使用平板电脑布局文件夹使我的应用程序崩溃

Question

我正在为手机和平板电脑制作一个具有不同布局的应用程序。对于平板电脑布局，我使用文件夹 layout-sw600、layout-sw600-land、layout-sw720 和 layout-sw720-land。但是当我在平板电脑或 avd 平板电脑上打开应用程序时，它会立即崩溃。当我在手机上运行它时，布局正常工作。可能是什么问题呢 ？我必须在清单中指定一些东西吗？请帮忙。 我粘贴 logcat 错误：

这是平板电脑的布局。它的所有drawables。

Answer 1

可能是什么问题？

您的内存不足：

08-16 22:30:13.234: E/AndroidRuntime(894): Caused by: java.lang.OutOfMemoryError

这个特定的OutOfMemoryError 是由加载可绘制资源引起的，可能作为布局中某些内容的背景。

无论出于何种原因，您正在测试的环境只为您的进程分配了 16MB 的堆空间，这在现代标准中是相当低的。平板电脑应该有更大的堆大小，专门用于处理更大的背景图像。如果您在模拟器上进行测试，请确保您的模拟器是真实的（例如，Android 4.x 用于平板电脑大小的模拟器图像）。
