即使应用程序被杀死，如何继续在前台启动的上传过程？

Question

我正在进行一个需要将文件上传到服务器的项目。要上传大文件，将花费很多时间。为了避免这种情况，我想到了从后台上传文件。为了从后台上传文件，我在该服务内部使用了服务，而我正在使用异步任务来上传文件，问题是上传开始时，如果删除该应用程序意味着终止该服务也将停止。如何解决这个问题。请在下面找到我到目前为止的代码片段

public class BackgroundService extends Service {

ProgressRequestBody.UploadCallbacks callbacks = new ProgressRequestBody.UploadCallbacks() {
    @Override
    public void onProgressUpdate(int percentage) {
        Log.i("percentage", "" + percentage);
    }

    @Override
    public void onError() {

    }

    @Override
    public void onFinish(int finished) {

    }
};


@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    String filePath = intent.getStringExtra("filePath");
    final int studentId = intent.getIntExtra("studentId", 0);
    int documentType = intent.getIntExtra("type", 0);
    uplodeBackground uplodeBackground = new uplodeBackground();
    uplodeBackground.execute(filePath, String.valueOf(documentType), String.valueOf(studentId));
    return START_STICKY;
}

class uplodeBackground extends AsyncTask<String, Void, Void> {
    @Override
    protected Void doInBackground(String... strings) {


        ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
        File file = new File(strings[0]);
        //RequestBody progressRequestBody = RequestBody.create(MediaType.parse("multipart/*"), file);
        ProgressRequestBody progressRequestBody = new ProgressRequestBody(file, callbacks);
        MultipartBody.Part[] part = new MultipartBody.Part[2];
        part[0] = MultipartBody.Part.createFormData("file", file.getName(), progressRequestBody);
        part[1] = MultipartBody.Part.createFormData("documentTypeId", strings[1]);
        RequestBody mStudendId = RequestBody.create(MediaType.parse("text/plain"), /*String.valueOf(studentId)*/strings[2]);
        Call<JsonObject> call = apiInterface.uploadFile(part, mStudendId);
        call.enqueue(new Callback<JsonObject>() {
            @Override
            public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
                if (response.isSuccessful()) {
                    if (response.body().get("status").getAsInt() == 200) {
                        Log.i("test", "Uploaded successfully..........");

                    }
                }
            }


            @Override
            public void onFailure(Call<JsonObject> call, Throwable t) {
                Log.i("test", "Failed successfully..........");
            }
        });
        return null;
    }
}

}

您在forground服务中调用您的AsyncTask类。只有在应用程序在后台运行时，forground服务才会被杀死。
