本文介绍了MLKit BarCode Sanner实施在执行ML Kit任务时导致内部错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
每次调用scan.process(image)都会导致onFailure调用，并出现以下错误:
Every call to scanner.process(image) is resulting in the onFailure call, with the following error:
有关任务失败原因的更多详细信息或想法吗?用条形码显示它似乎也不会改变这种行为.
Any further details or ideas as to why the task is failing? Presenting it with a barcode does not seem to change this behavior either.
使用Pixel 3a时会显示此错误，但由于SIGENV错误而使Nexus 5完全崩溃.在阅读总览
This error is shown when using a Pixel 3a, but totally crashes a Nexus 5 with a SIGENV error. I've been building my code from snippets while reading through the overview

推荐答案
通过阅读此.将OnCompleteListener添加到结果Task中，然后将imageProxy.close()放在其中，即可解决此问题.即:
Inadvertently found the cause of the error by reading this. Adding an OnCompleteListener to the result Task and placing the imageProxy.close() inside, resolved this. i.e.:
Task<List<Barcode>> result = scanner.process(image);
result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
@Override
public void onSuccess(List<Barcode> barcodes) {
// Task completed successfully
Log.i("CameraXApp3", "scanner task successful");
processBarCodes(barcodes);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Task failed with an exception
Log.i("CameraXApp3", "scanner task failed. Error:" + e);
}
});
mediaImage.close();
imageProxy.close();
没有错误
Task<List<Barcode>> result = scanner.process(image);
result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
@Override
public void onSuccess(List<Barcode> barcodes) {
// Task completed successfully
Log.i("CameraXApp3", "scanner task successful");
processBarCodes(barcodes);
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
// Task failed with an exception
Log.i("CameraXApp3", "scanner task failed. Error:" + e);
}
}).addOnCompleteListener(new OnCompleteListener<List<Barcode>>() {
@Override
public void onComplete(@NonNull Task<List<Barcode>> task) {
mediaImage.close();
imageProxy.close();
}
});
@Hoi想要抓住他应得的点时，将等待标记为答案.:)
Will wait to mark as answer in case @Hoi wants to grab the points, which he deserves. :)
