Question

我之前可以将图像上传到存储中，但是当我添加以下代码时，它现在无法存储。帮帮我。谢谢。

public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data)  {super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1 && resultCode == RESULT_OK && data != null) {
        imageuriOne = data.getData();

        CropImage.activity(imageuriOne)
                .setAspectRatio(1,1)
                .setMinCropWindowSize(400,400)
                .start(getContext(),this);
        if(requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE){
            CropImage.ActivityResult result = CropImage.getActivityResult(data);
            if(resultCode == RESULT_OK) {
                Uri resultUri = result.getUri();

                File compressFilePath = new File(resultUri.getPath());

                if (compressFilePath.exists()) {
                    try {
                        Bitmap compressUri = new Compressor(this.getActivity()).setMaxWidth(800)
                                .setMaxHeight(600)
                                .setQuality(75)
                                .setCompressFormat(Bitmap.CompressFormat.WEBP)
                                .setDestinationDirectoryPath(Environment.getExternalStoragePublicDirectory(
                                        Environment.DIRECTORY_PICTURES).getAbsolutePath())
                                .compressToBitmap(compressFilePath);
                        ByteArrayOutputStream baos = new ByteArrayOutputStream();
                        compressUri.compress(Bitmap.CompressFormat.JPEG, 100, baos);
                        byte[] compress_byte = baos.toByteArray();
                        //require api level26 (error), current is 23
                        String finalByte = Base64.getEncoder().encodeToString(compress_byte);
                        Uri finalUri = Uri.parse(finalByte);
                        dpOne.setImageURI(finalUri);
                        numap.put(1, "" + finalUri);
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                }
            }
        } earlier code...public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1 && resultCode == Activity.RESULT_OK && data != null) {
        imageuriOne = data.getData();
        dpOne.setImageURI(imageuriOne);
        numap.put(1,""+imageuriOne);

    }
}
