AsyncTask安卓中的致命信号6 (SIGABRT)
AsyncTask安卓中的致命信号6 (SIGABRT)
提问于 2020-01-14 19:00:53
我正在异步任务中压缩Bitmap，并通过Bundle将其发送到另一个活动，我得到了这个崩溃。我在我的代码中调用Bitmap.recycle()。有时它会正常工作，下面是我的Logcat输出。

这个位图似乎已经被回收了。你不能使用回收的位图。您需要确保位图不会被回收，这是在compressImage中传递的。现在，您可以检查位图是否被回收以避免错误。
if(!bitmap.isRecycled()){
//bitmap is not recycled
}else {
//bitmap is recycled, use a default placeholder
