java.lang.OutOfMemoryError BitmapFactory.nativeDecodeAsset()

Question

您好，我正在创建一个关于交通标志的应用。交通标志为 .png 格式。其中一些我在horizo​​ntalscrollview 中显示。但是当尝试打开活动时，我从 android 市场错误报告中得到这个错误。这是我的错误报告：

谁能帮帮我？

Answer 1

“位图大小超出VM预算”错误实际上是在原生图形库（Skia）中。这有点令人困惑，因为问题实际上是 Skia 已用完本机堆中用于位图数据的内存。有关背景，请参阅BitmapFactory OOM driving me nuts。 为了解决这个问题，您必须仔细查看您的位图使用情况

• 确保不要让位图引用浮动
• 在空闲的位图/null onn 位图变为可用时进行回收（这似乎有帮助）。

Answer 2

使用采样读取位图。可能是由于内存泄漏而发生的错误。

BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 4;

Bitmap bitmap=BitmapFactory.decodeFile(path,options);
