我在我的Android应用程序中运行两个AsyncTask任务,这些任务来自同一个类但具有不同的参数.例如:

new myAsynckTask(a,b,c).execute();
new myAssyncTask(a,d,e).execute();

它们是并行执行还是按顺序执行？我问这个是因为当第一个开始时,显示执行的进度,当完成时我看到第二个需要更多时间才能完成但我看不到进度(我能看到矩形但进度条)没有显示20%..等等).这就像冻结但结果还可以.

我想要做的是按顺序运行它们,并能够看到它们中的两个进度.我在Android Jelly Bean 4.2.2 API Level 17上运行应用程序

我正在尝试创建一个简单的"Hello"Web服务,我收到以下错误:

type Exception report

你能解释一下在Tesseract ocr引擎上有什么立方体模式和立方体数据文件吗？使用它们有什么好处？

我如何训练希腊的tesseract获得更好的结果？

我正在尝试使用Tesseract TessbaseApi,我想使用两种语言,以便我可以识别例如英语和希腊字符.我在互联网上搜索,我发现Tesseract 3.02支持识别多种语言(合并两个OCR训练数据).但我如何在Android中使用它？可能吗？谢谢!
