android.view.InflateException：二进制XML文件行＃3：错误充气类<unknown>

Question

我试图把启动图像4.41 KB，我和我的三星S4设备制造到我的应用程序，但我得到下面的时候我的错误将它存储在这个目录下drawable-hdpi。我甚至试图将它存储在ldpi，mdpi，xhdpi和xxhdpi中，在这种情况下，我得到的是没有图像的白色背景。

我从具有800×600像素大小和494 KB互联网上下载的图像。我把它放在drawable-hdpi目录中，它工作正常（图像显示为飞溅），但我想把我自己的S4设备图像作为背景。我该如何解决它？

XML文件：

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" 
    android:background= "@drawable/splash_background" 
    > 

</LinearLayout> 

错误：

Answer 1

你正试图把可能有一个高分辨率的图像。这似乎是OutOfMemoryError的主要原因。

您可以使用Android资产Studio为各种屏幕密度的图像。 https://stackoverflow.com/questions/10754523/is-there-any-tool-which-can-a-resize-png-image-into-a-image-for-ldpi-mdpi-hdp

Answer 2

如果你想避免OutOfMemoryError，你可以做一件棘手的事情。

转到您的AppManifest.xml，并在应用程序代码，补充一点：

android:largeHeap="true"

这段代码会尽量避免您从OutOfMemoryError异常。它增加了您的应用程序优先级当任何用户打开了许多应用程序时，这将尝试从其他应用程序中清除一些内存，为应用程序腾出更多空间。但仍尝试缩小图像的文件大小，因为这样做肯定会更好。检查这个链接。我总是使用该工具：http://www.compresspng.com

还要确保你已经在你的AppManifest.xml中注册了你的新活动。即使是最好的开发者有时也会忘记这么做。

如果你仍然面临的OutOfMemoryError然后尝试做像什么Amey Shirke说。
