Question

我试图对我的位图图像进行居中裁剪，但是一段时间后在我的后续函数中它抛出OOM错误，结果应用程序崩溃了。我可以在以下功能中进行哪些更改以处理中心作物？

private Bitmap cropBitmap(Bitmap bitmap) {
    Bitmap bmp;
    if (bitmap.getWidth() >= bitmap.getHeight()) {
        bmp = Bitmap.createBitmap(
                bitmap,
                bitmap.getWidth() / 2 - bitmap.getHeight() / 2,
                0,
                bitmap.getHeight(), bitmap.getHeight());
    } else {
        bmp = Bitmap.createBitmap(
                bitmap,
                0,
                bitmap.getHeight() / 2 - bitmap.getWidth() / 2,
                bitmap.getWidth(), bitmap.getWidth());
    }
    return bmp;
}

这是我的错误日志

Answer 1

您的位图太大。这是显而易见的。
在清单中的android:largeHeap="true"标签下尝试application。
也许会起作用。
