Android :: Can I Download An SQLite Db On / Sdcard And Access It From Droid App
Jun 28, 2009
I already found out that there is no way to bundle files in an .apk and have them on /sdcard, the best option so far being to download the large files upon first run. I came accross a tutorial saying how to bundle an sqlite db with the apk and then copy it so that it can be accessed with SQLiteDatabase (thus doubling the space needed, and not using /sdcard at all).
http://developer.android.com/guide/topics/data/data-storage.html#db says all databases MUST be in /data/data/package_name/databases.
Is that really so? Is there a way to trick the framework into opening a database that is placed on the /sdcard partition? Is there a way to use another SQLite java wrapper/framework to access such databases?
If the answer to the above is 'No', what other options do I have? My data is very well represented in a relational model, but is just too big, plus, I want to be able to update it without the need to reinstall/upgrade the entire app.

So far we have developed apps in android that create database on runtime. We like to know how can we access a pre-built or existing database/sqlite file in our android app?

I use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?

I have an application with several tables, each being updated by AsyncTask fired by different Activities and used by UI with SimpleCursorAdapter. Though i am not developping a game, I would like to avoid to interrupt the user as mush as possible. Has SQLite is not multiaccess proof, what is the best way of handling such situation?
- I consider adding lock from each DB open and to each close sequence but this seems quite subject to bugs - The solution i am using now is that each DB access (read/write) is done in UI thread (when AsyncTask completes, DB write is done typically in onPostExecute), but that means user is blocked for several seconds during the DB write.
Is there any better solution for that? Should i use a ContentProvider? when i read "Content providers store and retrieve data and make it accessible to all applications", this does not seems to be what i need. Any idea?

I have a database that I have already populated locally. I want to bundle it with my applications and access it at runtime (never want to re-write it anywhere, nor write to the database, simply read). What is the path of a file that I have added to the bundle? And, can i use that path with a SQLiteDatabase.openDatabase ?

I'm developing an Android application with a database. That database will have more than three tables. Now I'm working on a class called DBAdapter to access the SQLite Database. DBAdpater will have five methods for every table on database (insertEntry, removeEntry, getAllEntries, getEntry and updateEntry). So, if I have five table, DBApadter will have more than twenty-five methods. I think is so huge. How may DBAdapter classes should be?

I know there are already alot of apps to protect the phones and its contents BUT is there anything stopping a thief from simply taking out the sdcard and putting it in another phone or reader to view and access the contents of the sdcard? If you plan on storing personal info on the card, whether it'd be photos / files etc It would be really good to know that even if the sdcard is taken they still cannot access the info. I would've thought this is a pretty common request. something like trycrypt or storage crypt for the microsd card would be really good.

I am using a mt6582m device with kitkat 4.4.2 with supersu. I can use root to write to system, data and cache using es file explorer, can also read and write to any sd card, but apps like titanium backup, online android backup, ram expander can't read/write to sd card.
Eg.1: ti backup read backups, can do all operation except backup and restore.
I had read a lot, changing backup path didn't worked nor any odex file is there. Using v6.1.5.6.
Eg. 2: ram expander can create swap file on sd but can read it saying 'not found'. Swap can be used with cache partition.
Eg. 3: online nandroid backup says pat not vaild.
I had tried, sd fix app, manually editing platform.xml, xposed module to 'handel external storage', change permissions using es file explorer, editing ramdisk.
There is storage/sdcard0 and 1
Also mnt/sdcard and mnt/sdcard2 (symlinked)
Also mnt/media_rw/sdcard0 and 1 (not readable even in es file explorer)

I have seen other posts similar to this one but none of the solutions listed work for me. When I use the following command: adb pull /data/data/com.mydomain.myappname/databases/MyDatabase.db / home/me the following error results. failed to copy '/data/data/com.mydomain.myappname/databases/ MyDatabase.db' to '/home/me/MyDatabase.db': Permission denied I have no problems with the emulator. I am using a Dev Phone 2.

I want to add a big feature to an application i am developping, but as this feature interest few people and is quite independant from the main part, I would like to put that in a seperate "plugin" application.Does anyone knows any design patterns, snippets, "reference" examples about such design?In particular that separate plugin application should be able to access some tables in the main application DB. Is it possible to do that without broadcast receiver? - the main application uses a TabActivity: is it possible that a the tabactivity instanciates an Intent Activity that is part of the plugin? - does the plugin can access main application preferences (not sure this would be necessary, but better to anticipate the question!) is it possible from the plugin to access main applications ressources?At least the 2 first points are mandatory for me.

I replaced my original sdcard with a sandisk 16gb card. Everything went well until I started getting these blasted read on errors. Earlymon suggested a fix from another board but I don't have a stand alone card reader so I couldn't do it that way.
I was wondering if I just backed up all my stuff from my sdcard to my iMac and then just reformatted my sdcard via the phone, would that solve my problems?

if there's any option to download the music out of Google play music all access I put in a playlist. I mean wouldn't it be nice to hear it with some other player, so if connection struggles the music doesn't stop playing. Yes offline mode in mobile version is available, but can I extract them out of it, to do the same at my PC.
The App Cloud music importer promises this much. But as I tried it, not one of my all access titles in the Playlists is shown and possible to download, just the ones I upped myself..

I tried to do a cyanogenmod update, but something went wrong and now I can't boot into android. I've tried going back into the recovery mode to reflash the rom, but it freezes there. I've also tried flashing clockworkmod recovery through ODIN and download mode, but the download back never moves at all, so I'm not sure if I can't use download mode or if it's just that ODIN isn't doing anything.

I am using Environment.getExternalStorageDirectory() to create a file and I will need to know if there is enough space available before I create and store the file.
If you can cite the Android Ref doc, that would be helpful too.

I want to port a program I wrote to android. The program is in c++ on windows and linux. The program uses dll's for a plugin architecture. New plugins can be added to the program by downloading a dll which the program loads from a specific folder.
My question is...
Is it possible to download dlls built for android to a directory on the sdcard then from native code load and use those dll's
