I have created a table with 2 rows in it. Each row has 5 TextViews with a default text of 0. There is also a button outside of the table. I am trying to figure out how to update each of the TextViews in each row on each successive press of the button. So on the first press of the button the first TextView in the first row should update to 1. On the second press of the button the second TextView in the first row should update to 2...etc. I can't figure out how to do this programmatically without having to code it all - is it possible? Basically I guess I need to build up the ID of the TextView dynamically. So if the TextViews have ids as item1, item2, item3 etc. Then I need to build up the findViewById(R.id.item + i); Obviously this is not possible but is there a way to do this?

I have a Windows web server already set up with a website (unlimited application pools) and I want to be able to access a database on that server via the Android app I'm developing. How can I do this? Can someone point me to a tutorial or give code example of how this cross-platform (Android/Java to ASP.NET/C#) communication can be done? (I'm trying to create a leader board or global scoreboard for my Android game on my server.)

I have a problem using adb shell on my Google IO phone. I get shell access, I can type cd /data/data, but then when I type "ls" it says "opendir failed, Permission denied". Same when I type "sqlite3". I didn't think I'd need to root my phone, but what setting did I miss to get access to data on the phone?
View 3 Replies View RelatedI am developing an application with TripIt integration and I make a call to their API and I get all my data in JSON format and save it in an object ListTripResponse. This object contains all the data I need over all the application. What I do now, I write this object to a text file (i serialize my object and save it as a file with ObjectOutputStream) and in every activity I read this file. But this file is pretty long and it takes a while to read it. And i have to use and read this object in every activity! Isn't there a better way to do this? I cannot save this file in a database because the structure is to complex.

View 9 Replies View RelatedI am experiencing a problem where when the android device wake up from sleep, the Activity would take forever to get redrawn(and have to terminate it most of the time). I am not sure why, but when I comment out the code below where it retrieves an object from the database based on id stored in the bundle, the problem goes away.
Not sure why the db transaction is causing an issue.
secondly, is it better to store the object in bundle instead of storing its id and retrieving it from db in onCreate?

I have an idea about using an old phone to tell me the temperature at a remote location. I need to know when a greenhouse or any remote location approaches freezing by sending an alarm to my computer or another Android phone. I thought about something similar to remote GPS locating but getting the temperature data instead of the GPS data. I could just leave my old Android phone in the Greenhouse. I know absolutely nothing about App development, I started to look at the SDK but first I needed to know Java, BASIC is as far as I ever got on a BBC.

I have a Samsung Galaxy S2 which I dropped and can no longer use the screen. The phone boots up but the screen remains black. I cannot access the files via usb, and debugging is not on so I assume I cannot use adb.

View 1 Replies View RelatedI am writing a program where I have to access some static data, and now I am looking for the best method of how to include them into the project.Reading in the data by parsing an XML is *slow* (even using the SAX parser). 2. Reading the data by parsing a CSV file is faster than loading an XML, but again is too slow. 3. Putting the data into a Java file directly (e.g. by defining an array) fails because Dalvik says it is too large. 4. Reading in the data using serialization is slow. The funny thing here is: It takes a bit longer than loading the XML file. 5. Reading in the data from a SQLite database is the fastest method until now. But a bad workaround is needed: A SQLite DB can not yet be read directly from the resources, but instead has to be copied to the cache or to the SD card - even for read-only access. Right now I am using method 5, but I would really like to use a more simplified and faster solution.
What I found out: Unserialization in Java is *fast* (reading a HashMap with 5000 integers and strings in 79ms on my PC), while the same action on my G1 takes over 13500ms. I know that I can not compare a PC to a mobile device. But still, there seems to be a big difference here. I think that the JRE directly copies the serialized data to RAM, while Dalvik seems to read every object step by step. Is this going to change in the future? And, most interestingly: what do you do to access lots of static information?
