database - Downgrading DB on Android -


मैंने परीक्षण किया है कि एंड्रॉइड के पास newVersion & lt; पुराने संस्करण से SQLiteOpenHelper.onUpgrade () विधि, यानी। यह एप्लिकेशन को अपने डेटाबेस डाउनग्रेड करना चाहता है

मैं इस मामले को संभाल नहीं करना चाहता, हालांकि मैं किसी भी तरह से उपयोगकर्ता को सूचित करना चाहूंगा कि मेरे आवेदन का एक नया संस्करण मौजूद है (जिसे उन्होंने जाहिरा तौर पर पहले स्थापित किया था) और यही वह होना चाहिए का उपयोग कर।

कोई भी विचार यह हासिल करने का सबसे अच्छा तरीका क्या होगा? टोस्ट ? अलर्टडायलॉग (लेकिन किस संदर्भ में)?

वास्तव में, आप उसे कॉल कर सकते हैं "पुराने" संस्करण से छोटा एक "नया" संस्करण के साथ विधि, लेकिन यह कब कभी नहीं होगा?

जब तक आप अपने उपयोगकर्ताओं को मैन्युअल रूप से अपने ऐप को पुनर्स्थापित करने की उम्मीद नहीं करते हैं, तो इसे पहले एपीके के साथ लिखा जा रहा है, कोई ज़रूरत नहीं है इस बारे में सोचने के लिए।

This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
