Android - 从其对象启动服务

Question

我正在开发一个应用程序，通过某些方法将文件上传到 Firebase存储。为此，我使用后台服务以避免中断这可能会导致一些错误。

问题是我的服务类应该获得一些对象，例如

public  StorageReference stoageRefer;
public  Uri fileUri;
public UploadFinishedListener uploadFinishedListener;

要使用这些对象我创建了setter，它将帮助我修改它们。

 public void setStoageRefer(StorageReference stoageRefer) {
    this.stoageRefer = stoageRefer;
}

public void setFileUri(Uri fileUri) {
    this.fileUri = fileUri;
}

public void setUploadFinishedListener(UploadFinishedListener uploadFinishedListener) {
    this.uploadFinishedListener = uploadFinishedListener;
}

从我的活动类开始，我将启动此服务并将其设置在我的服务对象上：

    UploaderService uploaderService = new UploaderService();

    uploaderService.setFileUri(fileUri);
    uploaderService.setStoageRefer(stoageRefer);
    uploaderService.setUploadFinishedListener(new UploadFinishedListener() {
        @Override
        public void OnUploadFinished(Uri Uri) {
            UserModel.setmImageUri(Uri.toString());
            mDatabase.child("Users").child(firebaseAuth.getCurrentUser().getUid()).child("DailyStory").setValue(UserModel);
            finish();
        }
    });

实际上，我尝试 赢得有用的方式。所有设置对象都是 null ;

  

startService（new Intent（this，uploaderService.getClass（）））;

我的整个服务类代码：UploaderService.class

public class UploaderService extends Service {


public StorageReference stoageRefer;
public Uri fileUri;
public UploadFinishedListener uploadFinishedListener;
Notification notification;

public void setStoageRefer(StorageReference stoageRefer) {
    this.stoageRefer = stoageRefer;
}

public void setFileUri(Uri fileUri) {
    this.fileUri = fileUri;
}

public void setUploadFinishedListener(UploadFinishedListener uploadFinishedListener) {
    this.uploadFinishedListener = uploadFinishedListener;
}


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

@Override
public void onCreate() {
    super.onCreate();


    startToUpload();

}

public void NotificationProgress(int progress) {

    Integer notificationID = 100;

    NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);


    Notification.Builder notificationBuilder = new Notification.Builder(getApplicationContext());
    notificationBuilder.setOngoing(true)
            .setContentTitle("File is uploading")
            .setContentText("It may take a while...")
            .setSmallIcon(R.mipmap.clagra_logo)
            .setProgress(100, progress, false);


    notification = notificationBuilder.build();
    notificationManager.notify(notificationID, notification);

}

public void cancelNotification(Context ctx, int notifyId) {
    String ns = Context.NOTIFICATION_SERVICE;
    NotificationManager nMgr = (NotificationManager) ctx.getSystemService(ns);
    nMgr.cancel(notifyId);
}

public void startToUpload() {

    UploadTask uploadTask = stoageRefer.putFile(Uri.fromFile(new File(fileUri.getPath())));


    uploadTask.addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception exception) {

            Log.d("uploadFail", "" + exception);

            Toast.makeText(UploaderService.this, "Something went wrong", Toast.LENGTH_SHORT).show();

            stopSelf();

        }
    }).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

            Uri downloadUrl = taskSnapshot.getDownloadUrl();

            uploadFinishedListener.OnUploadFinished(downloadUrl);

            cancelNotification(getApplicationContext(), 100);

            stopSelf();

        }
    }).addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {

            double progress = (100.0 * taskSnapshot.getBytesTransferred()) / taskSnapshot.getTotalByteCount();

            NotificationProgress((int) progress);

            Log.v("TAgTAG", progress + "");

        }
    });


}


public final IBinder mBinder = new LocalBinder();

public class LocalBinder extends Binder {
    public UploaderService getService() {
        return UploaderService.this;
    }
}

}

现在我想知道有没有办法从它的对象启动Start或Service。 提前谢谢......
