MLKit条形码扫描实现在执行ML Kit任务时导致内部错误。

英文:

MLKit BarCode Sanner Implementation results in internal error when executing ML Kit tasks

问题

以下是您提供的代码的中文翻译部分:

每次调用scanner.process(image)都会导致onFailure调用,并出现以下错误:

>错误:com.google.mlkit.common.MlKitException:执行ML Kit任务时发生内部错误

是否有更多详细信息或关于任务失败原因的想法?将其提供给条形码也似乎不会改变这种行为。

在使用Pixel 3a时出现此错误,但在使用Nexus 5时完全崩溃并显示SIGENV错误。我一直在阅读概述中的代码片段并构建我的代码。

入口点活动:

// 这里是您的Java代码

应用级Gradle文件:

// 这里是您的Gradle文件

从停止到启动应用程序的完整Logcat:

// 这里是您的Logcat日志

请注意,上述只是代码和文本的翻译部分,不包括任何其他内容。如果您需要进一步的帮助或解释,请随时提出。

英文:

Every call to scanner.process(image) is resulting in the onFailure call, with the following error:

>Error:com.google.mlkit.common.MlKitException: Internal error has occurred when executing ML Kit tasks

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.

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

通过阅读此链接,无意中找到了错误的原因。通过向结果任务添加OnCompleteListener并将imageProxy.close()放在其中解决了这个问题。即:

错误

Task<List<Barcode>> result = scanner.process(image);

result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
    @Override
    public void onSuccess(List<Barcode> barcodes) {
        // 任务成功完成
        Log.i("CameraXApp3", "扫描任务成功");
        processBarCodes(barcodes);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        // 任务失败,带有异常
        Log.i("CameraXApp3", "扫描任务失败错误" + e);

    }
});
mediaImage.close();
imageProxy.close();

无错误

Task<List<Barcode>> result = scanner.process(image);

result.addOnSuccessListener(new OnSuccessListener<List<Barcode>>() {
    @Override
    public void onSuccess(List<Barcode> barcodes) {
        // 任务成功完成
        Log.i("CameraXApp3", "扫描任务成功");
        processBarcodes(barcodes);
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        // 任务失败,带有异常
        Log.i("CameraXApp3", "扫描任务失败错误" + e);

    }
}).addOnCompleteListener(new OnCompleteListener<List<Barcode>>() {
    @Override
    public void onComplete(@NonNull Task<List<Barcode>> task) {
        mediaImage.close();
        imageProxy.close();
    }
});

将等待标记为答案,以防@Hoi想要获取积分,他应该得到的。 MLKit条形码扫描实现在执行ML Kit任务时导致内部错误。

英文:

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.:

Errors

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();

No Errors

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();
    }
});

Will wait to mark as answer in case @Hoi wants to grab the points, which he deserves. MLKit条形码扫描实现在执行ML Kit任务时导致内部错误。
