Android :: Any Database Of Different Device Configurations?
Sep 16, 2010
Is there a database anywhere that has all of the different devices that use the android operating system and what their technical specs are. Mainly screen size, screen density, internal storage, external storage, memory, etc.
You know that layout editor in the Android ADT plugin that lets you design the layout for ADP1, ADP2 and Nexus One, has anyone created other device configurations? It requires device information such as the x-dpi and y-dpi, which can be difficult to find out. I'm just wondering if anybody has added more device configurations they're willing to share? Perhaps together we could compile a huge devices.xml containing many of the devices out there. I'm fully aware the layout editor has many faults and cannot be relied upon but it is sometimes useful to rapidly preview how the layout might look on a wide variety of devices without switching between emulators.
I am using a db file and trying to access that file thru emulator it works perfectly fine but when i run the same app on device i get the error of no such table when i checked the path also it gives the right path and also the status of database open flag it returns true not able to guess what i am i doing wrong i have changed the permissions of database folder also for the emulator still no luck for that reason i wanted to check the folder of device are the db files present ...
I need to view the contents of my app's database on my device.I have read you can copy the database off the phone using 'adb pull' but I really have no idea how to issue this command, or where to find the database on the phone.
I have a app in development. It write data to a SQLite database. I've tested the app on my NexusOne over the weekend and have a bunch of data now in the database. I'd like to copy the database off of the phone and onto my dev machine.
I've tried to use adb pull <path to mydatabase> <path to my local machine> but it gives me a Permission Denied error.
How can I view the contents of my databases on the actual phone? I have followed the docs, using the adb and sqlite commands, but while these work fine on an emulator when I'm connected to the device I get a permissions error.
My plan is to prepopulate a database on a virtual device and then include database in the distribution of my app.However, I can't find the database file.Is it on my hard disk some where?How do I get it?I tried connecting using adb, I did an "ls" and then got really scared by this obscure list of directories.
I have an SQL lite database that I am trying to copy to the device. I was able to copy it to the emulator easily using DDMS however with the protection in the device, I cannot access the database files from the DDMS perspective.
I read many attempts here but couldn't find an easy solution.
Is there any way to attach the database (let's say named 'proj') and replace the currently created database proj in he device files?
The database file is identified by Dalvik when I insert it via the Dalvik Debug Monitor Server (DDMS), but when I add the database to the project assist it doesn't even upload to the device (as I can see through the DDMS). How to fix it?
I need to store and retrieve data from database when the device is in offline.When i run my application when the device have internet it fetches data and shows it user,but i also need the same output when the device is in offline by saving previously obtained data in database,anyone help me to implement it in my application.
I have trouble with finding my SQLite Database. As we can access the SQLite databases on a running emulator like below: adb -s emulator-5554 shell sqlite3 /data/data/package_name/databases/database_name But what if I am testing my application on real device(HTC Here-Android) ? where does i find my database?
I'm supposed to develop an app which behave like that: The User starts the app and can select between different configurations. Depending on the selection there are different colors, drawables and strings (e.g. urls for webservice-calls) to display. All the code-stuff is the same.
My first intention to do so was themes.... - is it possible to include somehow strings in themes? - what shall I do with styles which are referenced in some layout-xml (which are the same for all configs) and should use different colors. can't define colors or styles multiple times and don't want to change that manually (when user selects by code).
We want to store credentials for a user to a web service so the user doesn't have to repeatedly login, but we're concerned about security. We can't store a hash on the database, but we could probably use JCE encryption locally.
Is the content in SharedPreferences secured on the Android device?
I have a issue about spinner. I have many images in spinner when I select some image it shows the image and if I change the orientation like change to landscape its selected item list starts pointing the top one in the list. How shall I prevent to do that?
I just wanted to quickly bring up a topic that I had noticed lately. This comes to my attention for two reasons, firstly someone had posted that he had a user that reported a vague error message like "deleted all my pics", and the dev's were not able to reproduce it. Secondly, I myself have seen bug reports that really may not be relevant to my application. I had recommended to that first dev to just ignore the error for now since there was not enough info to reproduce it, and also for a second reason, there is no way to know what the user is truly running. For example, I've had a few bug reports, where a user says of my app "Doesn't work on HTC hero", but then another user will post "Works fine on Hero". I also had found a posting on the internet in a forum where a user had tried to use some of my software on a custom ROM, and he was having problems.
I guess the issue I'm bringing up here is that with the android market being somewhat "limited" in functionality, it makes it very hard on us developers to handle any customer issues such as bugs, etc. Especially since they could be using a custom ROM, or have ROOT access which also may even be affecting the software. My point is that developing for android in a professional manner is really not an easy task, and possibly it's just starting to be worth it (with market 1.6 at least there are some improvements) to develop paid apps. Basically Google needs to work harder though to improve this situation - and if users expect better apps (there are lots of complaints about the market being full of junk) then they need a way to report issues better, etc. And really it's not even up to a dev to try to match up with a custom ROM, technically it's not supported! (It's up to the dev of course if they want to investigate and try to support it).
What seems is going to happen is android is not only going to have multiple configs (which fortunately for us seems that the market will help filter them out if you app does not support them), but also we never can really know what is on a user's system. They may have some custom stuff, and they see a bug, but it could really not be our bug, but rather, in the system itself. This is why I still recommend that bug reports have to be weighed carefully as to whether they may really be a problem or not. It's an investment in time and while makers of free apps no doubt may not mind, those of us who develop paid apps don't want to multiply our costs by going down blank pathways.
I don't think I see any resolution to the situation in the near future, but I just wanted to make it clear that if a user reports a bug in their comments and gives you one star, it's not the end of the world. If you can reproduce it quickly and fix it, then that is great. But if not, move on - there is no way you can know exactly what they are talking about. I think some devs get too anxious about that one bad report. There is no way we are going to avoid that report! Because they may be using an untested ROM or such anyway, and it may not be worth your time to look at it in the long run. I've had few low stars here and there as well, and trust me, just keep improving your app and you will rise back up. As devs we need to encourage one another and I just want to try and help devs not get anxious about things that are really beyond their control.
I am trying to create a Video recorder but it looks like the video resolution is limited to 320 x 240. I tried changing it through MediaRecorder.setVideoSize() to something higher (e.g. 640 x 480) but gives me the same result. Is there a way to record video at higher quality? Also, when I try using the CAMERA as VideoSource instead of DEFAULT, the app force closes. MediaRecorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT) Which is the best configuration (encoding options?) to give the best video quality?
Android should become more like Windows. Android should be able to detect and recognize the different hardware configurations and adjust itself accordingly. This way, you hit two birds with one stone. No more fragmentation. No more differences in the UI, Custom UI will be entirely optional.
All the manufacturer has to do is make the hardware and provide the hardware drivers to Google. Simple as that. Everything will be so much easier. Phone manufacturers will be able pump out devices like crazy without any worries. Software developers won't have to worry about device compatibility. Come on Google, lets do it.
I'm typically asking for the best speed settings such as kernals. OC widgets. Nightlies. I'd like to hear the best scenarios and apply them to my hero. JIT enabled? overclocked to 768? JIT disabled? Did a lot of reading from the CyanogenMod-6 for Hero V6.0.0 - RC1 thread. I know what is best so far, but flashing collins battery tweak on top of the uncapped kernal is a benefit or a negative? Some say you don't need to flash it but why not when it's making the battery last longer?
I'm having some trouble with my Uni's WiFi in that it needs to use a manual proxy address to access properly. I've had a wee fiddle with many things and had a look on the marketplace but there doesn't seem to be anything that can help? (I'm still running 2.1 un-rooted btw) Heres what I'm dealing with - Web Proxy - University of Strathclyde
ive been looking for a week now i need some help connecting to a remote database...i want my app to get data out of the database and update the database.ive tried this http://www.helloandroid.com/tutorials/connecting-mysql-database but i dont understand it.
I'm trying to deploy an application with an existing SQLite database.I've been reading though the examples that are posted but they are always missing some part of the class. I feel like I'm trying to bake muffins but no one told me to use baking powder.Can someone post a full database helper class for depoying an SQLite database on Android? Edit : Delete old code because it doesn't work.
I'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?
I want to build my own cloned databases of all or some of the Android native databases like Contacts, Calllogs, Mediastore, Settings, etc. I want to know wheher it is possible and How I can know the database schemas of these databases? Is there any documentation on this?
Can someone explain a couple of very simple concepts to me - I'm interested in mobile devices running android and how they are identified over networks. Some scenarios: Device is connected over WiFi - presumably the device has a standard IP address as with any host and can communicate with any other android host over TCP/IP (assuming it knows the participating device's IP? device is connected over bluetooth - how are devices identified in this case? device is connected over mobile operator's network - this is the one I'm interested in and confused by - is there anyway for two or more devices to discover each other and communicate via the mobile operator's network? How does a device communicate with a backend server in this scenario? In other words, how do apps and devices communicate when not connected to a WiFi network?
I have developed and tested my app on the emulator, and now want to install it on my HTC device. the apk installs successfully, however my database is not going with it. I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem
