java.lang.OutOfMemoryError：无法分配带有16777216个空闲字节的571401228字节分配和直到OOM的495MB

我的android应用程序出错了。 我想使用viewPager作为android图像滑块，为此我得到了我的AndroidImageAdapter.java，但是当涉及方法instantiateItem时，应用程序中止，我不知道如何修复它。 我已经查看了失败并添加了

android:hardwareAccelerated="false" android:largeHeap="true" 

我的清单，但它仍然存在。 这是完整的错误代码：

Answer 1

571401228字节相当于11952 x 11952像素图像。 这太大了。

最有可能的问题是双重问题：

• 可绘制资源的分辨率本身就太大了

• 您将图像放在res/drawable/ ，因此它会根据您的实际设备密度进行升级，因此它比您开始时的尺寸大4倍或8倍

不要将位图放在res/drawable/ ，这是res/drawable-mdpi/的同义词。 要么为各种密度创建可绘制的密度相关版本，要么将此drawable放在res/drawable-anydpi/ 。 此外，请确保分辨率合理。
