我在捕获图像并从图库中获取图像时收到此错误。

【问题讨论】：

您能指出导致此崩溃的代码行吗？
压缩后检索到Bitmap.compress(Bitmap.CompressFormat.JPEG, 90, stream);
你的retrievedBitmap已经被回收了，但是我不知道为什么在你提供的代码中，请像调用commonImageToFile的方法一样发布更多代码

标签： android bitmap image-compression

【解决方案1】：

您将回收的位图传递给您的commonImageToFile 方法。您可以检查您的位图是否被回收：

if (retrievedBitmap.isRecycled()) { 
    // do your error handling here
    return; 
}

这必须在您致电retrievedBitmap.compress(...) 之前完成。如果您捕获布局并想保存它，这个问题可能会对您有所帮助：Can't compress a recycled bitmap
