Is it possible to preserve file-persisted data when upgrading an app? For example my app stores data under /data/data/mypkg/store. I would like the store directory to be preserved when user upgrades my app.

Android :: Preserve Data In Views When Switches Between Landscape And Portrait?

Feb 9, 2009

1) Does Google think there will only be one screen size on Android phones? The reason I ask is because I haven't been able to find anything on "variable" layouts in Android? I would like to create a layout with 2 webviews, one 80% of screen height and the other 20%. Is this even possible, or do I need to assign the height of each as a static "px" value?

2) How do I preserve the data in my views when someone switches between landscape and portrait? I doubt it's hard, but I've not been able to find it. Can someone post an example?

Android :: Storing Data On SD Card In Froyo - Files Deleted When Upgrading

Jul 24, 2010

I have an application which resides on the phone memory but downloads large data to the SD card on first launch (the app needs to be able to work without an internet connection most of the time) When using the recommend directory given in Froyo it seems all files on the SD card are deleted when I install a newer version of the .apk. I'd preferably like the files removed on uninstall, but not on upgrade since the files on the SD card aren't going to change between application versions, and forcing the user to re-download a large file that is independent of the application version does not seem reasonable. At the moment it seems I'm forced to use a different directory to the recommended one in order to stop Froyo deleting all the files when the application is upgraded. Am I doing something wrong, or is this how it is supposed to work (I'm guessing it is)?

Android :: Upgrading To Sdk 1.5

Jun 13, 2009

I run into problems when creating the AVD. It says do this: Open a command-line (e.g.,"Command Prompt" application on Windows, or "Terminal" on Mac/Linux) and navigate to your SDK package's tools/ directory. First, you need to select a Deployment Target. To view available targets, execute: android list targets

From the terminal, I navigate into the directory of the SDK on a Mac and I call the command listed above: myMac:Mobile jaredfurgal$ cd android-sdk-mac_x86-1.5_r2 myMac:android-sdk-mac_x86-1.5_r2 jaredfurgal$ cd tools myMac:tools jaredfurgal$ android list targets -bash: android: command not found..........

Android :: Best Way To Store Application Data / When Data Stored / Data Format Could Change In Future Versions?

Mar 4, 2010

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

Android :: Adding To A ROM And Upgrading?

May 6, 2010

I have a couple of questions for any Rom developers/experts on here regarding things that can be done with Android ROM's.

1) Is a parser Rom upgrade possible? So is it possible to change a small part of a ROM and then allow users to upgrade their ROM easily?

So can I change a part of a ROM and then a customer can upgrade to the newer ROM without having to be technically savvy and needing to root and flash their devices?

2) Can a change be burnt into a ROM so that when a user selects "Restore Factory Settings" that it doesn't remove the upgrade to the ROM?

3) So essentially I want to know if its possible (with a device manufacturers permission) to add to a ROM some small additional parts and then give this new ROM version as a firmware upgrade to the device so that a user only has to "upgrade" and not go through the process of rooting and flashing there device?

Android : Backup Before Upgrading To 2.2

Nov 22, 2010

A few weeks ago, I received a notification saying I could upgrade to 2.2 but that I should backup my phone first. I did not upgrade at that time because I didn't know (and still don't know) how to backup my stuff. I cleared the notification and have not seen it since. 1. Ideally, I would like to backup my applications, music, and mail accounts so that I can easily reinstall them after upgrading to 2.2. What is the best way to do that, keeping in mind that I am a relative beginner at this stuff? 2. Since I cleared the notification, I do not see a way to upgrade to 2.2. I looked through "Settings" and a few other places, but haven't had any luck. What would I have to do to upgrade to 2.2? To be clear, what I'm trying to do is upgrade to 2.2 and not have to rebuild my list of applications, mail setup, etc.

HTC Desire :: Upgrading To Android 2.2 Error

Oct 25, 2010

I was trying to upgrade from Android 2.1 to 2.2 with the following guide
Droid Den - Phone Guide: How To Install Rooted Android 2.2 On Your HTC Desire - Droid Den

Once the phone was done flashing DeFrost, with ROM manager, I restarted it. However, the phone will not boot. When powered on, all I can see if the green HTC logo against a white background.

What do i do now?


I managed to got past the HTC Logo screen where it would show a Red/Green/Yellow/Blue X and then boot into Android 2.2. I did this by clearing the storage data in the bootloader and restarting.

I would have no phone reception and is unable to get wifi connection. and would get an error message saying Process system is not responding at start up. Further, the phone keeps restarting by itself.

Also, SD card not detected and i would get horizontal line noise on the screen.

2.1 Update :: Problem After Upgrading To Android 2.1

Nov 19, 2010

After upgraded my X10 Mini Pro to Android 2.1, when I tried to connect my phone to PC Companion 2.0, after selecting USB connection on my phone, my phone automatically re-started! After restarted, my phone was locked (i.e. no response whatever I touched the screen or pushed the keyboard), there was an error message on my phone that there was no SIM card in my phone (in fact, I had not taken out the SIM card). The phone resumed to work only after I disconnect the USB cable from my phone.

I tried to switch off the phone (even took off the battery) several time and tried again, the same occured. Before upgrading, everything worked fine. What should I do? I can't downgrade it back to Android 1.6.

So I recently bought a Droid, and I haven't bought any apps yet, but I've been using the free trail of Eray, and I really like the functionality of it so I'm thinking of purchasing it. My question is, what happens when there is eventually an upgrade for an app you have paid for? Are those upgrades free, or do have to pay for the upgrades?

Android :: Upgrading To 1.5 - Radio's Signature Error

Jun 6, 2009

My phone was updated to 1.5 this week. I have been waiting to update my development environment, until the phone was upgraded. The ide started out smoothly, I even updated my new Colorthon program library and posted the compiled version on the marketplace.

Next I decided to upgrade Radio's Exercise Buddy. Got a signature error. I worked around it by giving it a new namespace, but this is far from ideal, because now my users will have to use a migration tool, to bring their data over. Is there a better way to do this? Also, If I change the namespace, can I still have my paid users get a free upgrade? Also, I know that many developer's have upgraded earlier, but I wanted to wait until I had the updated phone. If this is a common problem, please refer me to the thread to read.

Android :: Users Have Trouble Upgrading My App In Market

Oct 12, 2009

I've had more than one user say they have trouble when they "upgrade" new versions of my app in Android Market. One woman says it takes her several "days" to successfully do it (I presume that means multiple attempts spread out over time).Can this be on my end? I upgrade my database on each rev - basically I retreive the user data and stick it in the new database that ships with my app. But I think the complaint is about something different. Has anyone else received comments about anything similar? I am concerned people uninstall my app just because of this issue,
