如何解决Imagine SDK android图像处理过程中的“内存不足”问题

因为我正在为我们的应用程序实现OCR和Imagine SDK，所以我需要你的帮助来解决这个问题。

我有一个像下面这样的方法。

public void ImageProcessing(View v) {

        try {

                 MIContext _miContext = MIContext.getInstance();
                _miContext.clearAll();
             Uri _imageUri = Uri.fromFile(GetImageFile("form.jpg")); // GetImageFile() will return a file
            ImageOperation  _imageOperation = ImageOperation.AUTO_ENHANCE;
            OperationController _operationController = _imageOperation.getController();
                _miContext.loadSourceImage( _imageUri, this );
                final FineOperation fineOperation = _operationController.createOperation();
                _miContext.run( fineOperation );
        } catch (Exception e) {
                Log.v("mango", e.getMessage());
        }

}

当我执行它时。它返回“内存不足：堆大小= 7943KB，分配= 4113KB，位图大小= 24888KB，限制= 32768KB”

下面是我的logcat输出。

我做错了什么？麻帮帮我们

答案 0 :(得分：0)

您可以尝试增加应用程序的已分配内存。在android中，每个应用程序都会分配一大块内存。但在图像处理应用的情况下，它很可能没有那个记忆。 还可以尝试手动清理应用中的内存。 android垃圾收集器通常有位图图像内存泄漏。 你可以通过以下链接得到一个很好的阅读 bitmap memory managment

在Manifest文件的应用程序标记中使用它。

android:largeHeap="true"
