Glide 仅在某些设备上返回位图

Question

我正在使用 Glide 从 URL 中提取位图并将其显示在 ImageView 上，并通过函数（Firebase ML 套件模型）运行显示它。但是，在某些设备上这不起作用，我相信不会返回有效的位图。我知道它适用的一些设备是 Pixel 3 XL、Pixel 3a 和 Samsung S10e。但是，它不适用于 OnePlus 6 或三星 A5。

在一个 Activity（MainActivity）中，我启动相机应用程序，然后将 url 传递给另一个 Activity（PredictionResultActivity ).以下函数的前两个将捕获的图像保存到 url，第三个函数将 url 传递到 PredictionResultActivity：

// Function to call when diagnose plant button clicked
    public void capturePlant(View view) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        // Ensure that there's a camera activity to handle the intent
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            // Create the File where the photo should go
            File photoFile = null;
            try {
                photoFile = createImageFile();
            } catch (IOException ex) {
                // Error occurred while creating the File
            // TODO: error handling
            }
            // Continue only if the File was successfully created
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this,
                        "com.sproutleaf.android.fileprovider",
                        photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
                startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
            }
        }
    }

    // Create image file of captured plant
    private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "JPEG_" + timeStamp + "_";
        File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(
                imageFileName,  /* prefix */
                ".jpg",         /* suffix */
                storageDir      /* directory */
        );

        // Save a file: path for use with ACTION_VIEW intents
        mCurrentPhotoPath = image.getAbsolutePath();
        return image;
    }

// On result of activity launched from intent
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // If requestCode = camera app launched
        if (requestCode == REQUEST_TAKE_PHOTO && resultCode == RESULT_OK) {
            // Send path as intent
            Intent intent = new Intent(this, PredictionResultActivity.class);
            intent.putExtra("capturedPhotoPath", mCurrentPhotoPath);
            startActivity(intent);
        }
    }

并且在 PredictionResultActivity 的 onStart 方法中：

 Intent intent = getIntent();
        mCapturedPhotoPath = intent.getStringExtra("capturedPhotoPath");
        Glide.with(this)
                .asBitmap()
                .load(mCapturedPhotoPath)
                .into(new CustomTarget<Bitmap>() {
                    @Override
                    public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                        mCapturedImageView.setImageBitmap(resource);
                        try {
                            runInference(resource);
                        } catch (FirebaseMLException e) {
                            e.printStackTrace();
                        }
                    }

                    @Override
                    public void onLoadCleared(@Nullable Drawable placeholder) {
                    }
                });

在正常运行的设备上，位图显示正常，runInterference(resource)正常工作。在不工作的设备上，不会显示位图，也不会调用来自 runInterference(resource) 的回调。如果有人对为什么这在某些设备上不起作用有任何想法，我将非常感激。谢谢！

问题实际上是某些设备在相机意图期间破坏了 activity。我遵循了以下答案并且有效：

这是我的代码：

 @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        if (mCurrentPhotoPath != null) {
            outState.putString("cameraImageUri", mCurrentPhotoPath);
        }
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        if (savedInstanceState.containsKey("cameraImageUri")) {
            mCurrentPhotoPath = Uri.parse(savedInstanceState.getString("cameraImageUri")).toString();
        }
    }
