内部文件自动删除？

Question

我的应用程序将外部捕获的照片复制到内部存储器。后来或立即将文件上传到在线世界中的服务器。在某些情况下，要上载的文件不存在导致FileNotFoundException。 78％的病例发生在小米设备中。

这是因为任何内存更清洁的应用程序？或任何相关的许可？ 即使是可能出现问题的指示性想法也将受到赞赏。

传输文件方法

  public File transferFile(File file) {
    FileOutputStream fos = null;
    FileChannel inChannel = null;
    FileChannel outChannel = null;
    try {
        File transferredFileTo = new File(file.getName());// have the original name as the name in internal memory
        inChannel = new FileInputStream(file).getChannel();
        fos = context.openFileOutput(transferredFileTo.getName(), MODE_PRIVATE);
        outChannel = fos.getChannel();
        inChannel.transferTo(0, inChannel.size(), outChannel);
        return transferredFileTo;
    } catch (FileNotFoundException e) {
        e.printStackTrace();
        Crashlytics.logException(e);
    } catch (IOException e) {
        e.printStackTrace();
        Crashlytics.logException(e);
    } finally {
        try {
            if (inChannel != null && fos != null) {
                inChannel.close();
                fos.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
            Crashlytics.logException(e);
        } finally {
            //ultimately delete the file from gallery
            deleteLatestFile();
            deleteFileFromTempFolder(file);
        }
    }
    return null;
}
