General :: Unable To Access Application Data From SD Card After Factory Reset

Mar 2, 2013

Yesterday I tried to install a custom ROM on my device (HTC Evo 3D GSM Europe) for the first time and it took close to 12 hours to get it from ICS 4.0.4 to ICS 4.0.3 (when my intention was actually JB 4.2). Let's just say that forgot to backup his Shipped ROM, then installed JB, was incompatible with the boot loader, tried desperately to find a compatible shipped RUU that worked with the CID, spent countless hours searching in xda-developers and then finally settled for a custom ICS ROM until some time in the future.

Now on to my problem. Prior to my Factory Reset, I had moved all applications to the SD card. A simple look-over in the file system indicates all the data is still there, but reinstalling the applications and even moving them back to the SD card doesn't seem to give them access to the prior data (saved games, stored profiles, lists and anything else I might have done). It's as if the app has been installed for the first time.

Is there any way to "link" the data back to the apps (after yesterday's endeavor I ended up with a rooted phone, at least)?

HTC Droid Eris : Sd Card Folders - Access Other Folders With Saved Data

Feb 17, 2010

I usually view email with attachments from my pc because I usually lack the time to download the attachment. Today, I had some spare time so I tried to download an attachment. It downloaded fine but when I went to view it, I received a pop-up box to save it to the sd card. After pressing ok, I was told the save was successful but now I can't find it. Aside from pics and videos, how do I access other folders with saved data?

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.)

Android :: Way To Get Access To Data On Phone?

Jul 9, 2009

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?

Android :: Offline Access To Data

Nov 30, 2009

I 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.

Android :: Mounted SD Card Access

Oct 4, 2009

Can an Activity still have read/write access to an SD card after it has been mounted to USB storage (connecting USB and selecting Mount from the resulting notification screen). In other words, does mounting the SD card lock out system access until USB is disconnected. I need to create a live channel between an application and an external USB device and I'm running out of options.

Android :: Why Do I Get Access Denied To Data Folder When Using Adb?

Android :: Data Passing And Database Access

Sep 23, 2009

I 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?

CODE:...............

Android :: Want To Access Temperature Data Remotely

Sep 23, 2010

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.

Android :: High Performance Access On Static Data

Nov 24, 2009

I 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?
