java - MLKit BarCode Sanner Implementation 在执行 ML Kit 任务时导致内部错误

转载作者：行者123 更新时间：2023-12-05 00:09:42

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

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

关于任务失败的原因的任何进一步细节或想法？用条形码出示它似乎也不会改变这种行为。

此错误在使用 Pixel 3a 时显示，但在 Nexus 5 上完全崩溃并出现 SIGENV 错误。在阅读 overview 时，我一直在从 fragment 构建我的代码

最佳答案

无意中通过阅读this找到了错误原因.将 OnCompleteListener 添加到结果任务并将 imageProxy.close() 放入其中，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) {
        // 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();
    }
});

将等待标记为答案，以防@Hoi 想要获得他应得的积分。 :)
