致命异常：android.graphics.BitmapFactory.nativeDecodeStream上的main java.lang.OutOfMemoryError(本地方法)

运行我的应用程序时,我一直收到此错误.该应用程序可以正常编译,一旦我开始与它进行交互(ImageSlider),有时它会崩溃并显示该消息.

评论

我看到了其他一些线程,但是它们对我的情况没有帮助,或者至少无法实现.

知道如何解决这个问题吗？

解决方法:

如果Google文档没有帮助(他们有一些巧妙的技巧),作为最后的选择,您可以尝试添加
android：largeHeap =“ true”到< application> AndroidManifest.xml中的代码.但实际上,不得已.
