Android :: Publish An Application Update On Android - Market Without Deleting Local Database And Local Files

Nov 11, 2010

I published an application that stores data in a local database.

Now I have to publish an update to this application to fix some little bugs, but I am afraid that downloading and installing the update will delate the local database associated with the previous version.

I would like to know how the update system works. Will installing an update completely delete all the apk, files, databases associeted with the previous version?

If so, how can I avoid this in my code?

Android :: Utc Timezone - Translate Database Table

Jan 22, 2009

to dear all Android developers, I need to know the UTC bias of my phone to correct the UTC time information I got from a site. I have read earlier posts and already found the solution to get TimeZone information from the "System.currentTimeMillis();" method. However, I need to translate the TimeZone (as like, "Asia/Taipei") to the UTC bias that it has to be (as like, "UTC+8" or other formats). Does anyone know the actual API solution? I have surveyed android.util.TimeUtils and found nothing to do this. The worst solution may I have is to build a "TimeZone/UTC" database table to translate this..

Android : Delete Row In Database Table Given One Column Value - Which Is A String

Jul 22, 2010

I have a table with column headings: | _id (long) | Name (String) | x (integer) | y (integer) |

I want to delete the row in the table that has Name myName.

// In onCreate
dbHelper = new DBAdapter(this);
dbHelper.open()

// Function in DBAdapter class
public boolean deleteTitleGivenName(String myName)
{return dbHelper.delete(DATABASE_TABLE_2, KEY_NAME + "=" + myName, null) > 0;}

// Function call in java code
dbHelper.deleteTitleGivenName(myName); // this is where my code fails

dbHelper.close();

Just as a note: myName is for sure in the database. Also, I can not use the ROWID since I am getting myName from a ListView.

I just started programming with Android and I have tried for days to solve this problem.
Is my WHERE clause correct (KEY_NAME + "=" + myName)?

Android : Way To Load Flat Files Into Droid Database Table

Jan 21, 2010

In Android when you upgrade a database all data is lost. I'm going through a phase of development right now that is forcing many database upgrades. I don't want to lose all my data (and have to manually re-enter it) each time I upgrade my database. I would like to store my data in flat files and load those flat files into their respective tables each time a database upgrade occurs.

My questions is: What is the best way to go about this on the Android platform? Where should I store the data files (res/raw???) What sql should I execute to load these files?

Android : Delete One Specific Table Of A Database - Leave Rest Intact

Apr 23, 2010

I have a database where I store two different kinds of data. One table is for favorite routes, the other stores the retrieved routes from a server.

I can retrieve the routes etc just fine. But after retrieving the first Route, pressing back or HOME, and then retrieving another route, the routes table is filled with all the old routes plus the new ones.

So my question: how do I delete ONLY the routes table and not the whole database because I don't want to delete the added favorites?

I found the following function in the android docs:

public int delete (String table, String whereClause, String[] whereArgs) and I tried to implement it, but I must pass a SQLiteDataBase as an argument. But how?

I implemented: public void deleteTableRoutes(SQLiteDataBase db){ db.delete("routes", null, null);}

But I want to call this function from a different class where I have no reference to the database.. so what do I have to pass as an argument? Or how do I get a reference to my database?

I build my database upon the code example of the NotePadExample from the dev docs.How to solve this problem?

This is an extract of my class from where I want to call deleteTableRoutes(...)

private String start_from;
private String destination;
private int hour;
private int min;
private int day;
private int month;
private Source source;
private List<Element> tempList;
private List<Element> routes;
private String startT = "";
private String arrivalT = "";
private String duration = "";
private String line = "";
private boolean first=true;
private List<ResultElement> finalResult;
private List<Element> results;
private DbAdapter mDbHelper;

Android :: Insert Data On Sqlite Database Table From Word Or Excel Document?

May 22, 2010

In my project, I would like to create a database with single table. I would also like to insert data on this table from word or excel document. is it possible? if so please how can I do it? some code snippets would be of great help. I have four different activities which I would like them to interact with this single table. the first is the main activity and its purpose is just to launch the other three activities according to user choice. so it has no interaction with the DB. but the other three activities will read from the table whenever called. Can you please tell me how to call the dbhelper on these activities? I am unable to do this and I am currently creating one db per each activity which is not the optimal way.

Android : Can SAX Use A Local Resource XML File?

Jul 26, 2010

All of the android examples for XmlPullParser pull from a local resource file, and all of the SAX examples pull the XML from a URL. I've been told SAX is faster, so I'm trying to use that to pull data from a local resource file (res/xml/thefile.xml)

The example code I'm working off of is here. So in that example, the code I want to change is:

URL url = new URL("http://example.com/example.xml");
...
xr.parse(new InputSource(url.openStream()));

Instead of using URL, I want to use getXml(R.xml.thefile)
Is that possible, or does SAX need to get data from a URL?

KitKat 4.4 :: Google Photos Local Folders Auto Backup?

Apr 21, 2014

If auto backup is enabled in Photos, any images I download are also backed up. This happens regardless of whether 'back up local folders' is on or off, and even if I've explicitly disabled uploads for the Downloads folder!

I only want to backup photos I take, not all the junk I download. It's clearly broken.

Android :: Open A Local App File In Another App Via An Intent

Nov 8, 2010

I don't want to store said file on the sdcard in this case. The file also cannot be storage directly in the apps local files directory. It needs to be in a subdirectory, so it cannot write the file using openFileOutput() and MODE_WORLD_READABLE.

The app may download files small files like pdfs and store them locally in a subdirectory. I would like to be able to have the user open these files if they have an app that can open them.

For example here is an intent for sending a pdf:

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

path being something like: /data/data/packagename/files/subdir/example.pdf

That intent will open a pdf viewer, but the viewer is unable to open the file. I assume this is a permissions issue. I tried Mark Murphy's suggestion here: http://groups.google.com/group/android-developers/browse_thread/thread/4e55d869213483a9/b7270078ac1a2744?lnk=raot of using Runtime.getRuntime().exec("chmod 755 " + fileName); but it didn't make any difference. He also suggested a Content Provider but I would like to avoid it if I can because it seems like a lot just to get this file over to another app.

If the content provider is the only option, do I have to save the file to the content provider or can I just use the content provider as a pass through to get it to the other app when I need to?
