I am trying to save data in local storage by using get storage. I created a instance of get storage (box) and write data in it in our services screen.
Here I created a instance of get storage
Here I write data in box
So I am trying to read this data from another screen of project but a error occur.
Here box can not be recognized
Please give your solutions Please.
Thanks
to read data from get storage you need to use box.read(key):
in your case if you want to read Name:
var name = box.read('Name');

I can successfully upload the sqlite file from iOS to server, however having trouble with android, getting a TiBlob: java.io.FileNotFoundException: Resources/db_name error. To open the database i use var backDatabase = Ti.Database.open('db_name'); i am adding this to the post in the HTTP Client.
file : OS_IOS ? backDatabase.getFile() : Ti.Filesystem.getFile("./db_name"),
So i guess the question is what can i use to get the file in android?
If I understood correctly, you want to download from a server a SQLite database programming with Android, is it that?
I think this is a good answer: https://stackoverflow.com/a/7162385/6133630
Do not use any library, simply take the InputStream that returns the connection and copy byte to byte in s3db file.
On Android, the database is created on the internal storage (you could
move it, or use the install procedure to put it on external storage).
The standard location on internal storage is
/data/data/com.example.yourappid/databases/dbname

Or if you are using SDK 5.4.0+, you can actually use the file property to get the db file.

I have developed an app that is to save daily income and outcome. Those income and outcome will be update every time. If my phone is break down, my app's data will be lost? How should I do to save income and output record.
If you have a external storage on your phone, such as an SD card, you could save your data to a SQLite database located here, so you're not losing you data even if you do a factory reset. Most devices won't never delete your SD Card data during a factory reset, some other may ask you if you want to.
Any information android would by default keep in the data folder, except non critical stuff (remembering user's login, personal settings...) should be saved in the external directory.
To write to the external storage, you must request the WRITE_EXTERNAL_STORAGE permission in your Manifest, and while creating the database, call an overloaded method that allows you to specify its location.
Upload (Post by using php) details to website database by using json
api.
Or save data (encrypted text or other file) in memory card.
Or use sqlite technology.
I have android application, I use SQLite data base in my application, I have a question about data base in setting -> application manager if I select clear data or clear cash, our data base deletes, but I need data base. For example user remove data base suddenly after that my program does not work, my program is related to data base, how do I do, how can I resolve my problem?
You will need to find some way to backup your database to the SD card. You could just dump it as a CSV-type file, which would exactly mimic the structure of a database, or else create some other kind of format which would work better for you. And then in the case that the database is cleared, you will need to parse the text file you created as the backup, and put it all back into the database.
I am working on some application, where I am storing some of my application data in SQLite DB. If any user clears the data, my data gets cleared. Through How to disable the Clear Data button in Application info of Manage appliaction and http://groups.google.com/group/android-developers/browse_thread/thread/b1091f190f7356b7 these links, I found that we cannot disable clear data button, But my question is Is there any way to catch this action(clear data) in the application? Is there any intent in android to notify this action ?
Thanks in advance

A possible workaround is to program your application to use a SQLite database on external storage. SD card etc. just create a folder on your SD or whatever storage you want, place the .db file in that folder and use that instead of the default storage location. By default, SQLite databases are stored in the data folder(device not rooted so dont know where in the data folder), which is not accesible unless you rooted your device.
There are tutorials out there that use this technique.
Note that, its likely that when you delete your app, the data will persist.
Don't know if that is desirable.
You can do one thing You can create a test table in your DB and insert some data in it. Every time you run the application you check the value of the table exist or not. If data exist that means DB value is not reset and if Table is empty you get to know that DB data is cleared and insert the data again for the next time check.
I'm implementing the application just like tracking the user's traveling.
Now I'm using the SQLite database which is record the location, time,and date
then automatically send to the MySQL server via JSON if the Internet is connecting.
But I want to do like the following:
1) I would like to keep data as a text file of each traveling before send to server.
2) I don't know that I should record data in SQLite before write as a file or not?
3) I also need to list all files in the document menu to show user all files
and check the status of all files are completely sent or did not send.
I tried to search for the good tutorial and any examples but did not find them yet.
If anyone have a good tutorial for write/read file and any idea for these, please suggests me.
Thank you so much
Here is good tutorial how to write data to file and save it to SD card.
