捕獲的圖像不會保存到某些 android 設備上的存儲

Question

我正在使用 java 構建一個 android 應用程序。https://github.com/skydragon1115/Android_Camera

但圖像不會保存到以下設備的存儲中。

Galaxy Feel2 SC-02L 操作系統：Android 10

dtab Compact d-01J 操作系統：Android 7.0

這個 function 正在處理其他的。

 try {
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            String fileName = timeStamp + ".jpg";

            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DISPLAY_NAME, fileName);
            values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpg");
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                values.put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/Camera/");
                values.put(MediaStore.MediaColumns.IS_PENDING, 1);
            } else {
                File directory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
                File file = new File(directory, "Camera/" + fileName);
                values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
            }

            Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            try (OutputStream output = getContentResolver().openOutputStream(uri)) {
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, output);
            }
        } catch (Exception e) {
        }

我找到了原因。

        try {
            String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
            String fileName = timeStamp + ".jpg";

            ContentValues values = new ContentValues();
            values.put(MediaStore.Images.Media.DISPLAY_NAME, fileName);
            values.put(MediaStore.Images.Media.TITLE, fileName);
            values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpg");
            values.put(MediaStore.Images.Media.DESCRIPTION, "captured image");

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                final String relativeLocation = Environment.DIRECTORY_DCIM + File.separator + "Camera" + File.separator;
                values.put(MediaStore.MediaColumns.RELATIVE_PATH, relativeLocation);
                values.put(MediaStore.MediaColumns.IS_PENDING, 0);
            } else {
                File directory = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);
                File file = new File(directory, "Camera/" + fileName);
                values.put(MediaStore.MediaColumns.DATA, file.getAbsolutePath());
            }

            Uri uri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            try (OutputStream output = getContentResolver().openOutputStream(uri)) {
                bitmap.compress(Bitmap.CompressFormat.JPEG, 100, output);
            }
        } catch (Exception e) {
        }
