Android :: Use Multiple Files To Store String Values
Jun 23, 2009
Is it possible to store strings values in multiple files? Eg, strings.xml, strings1.xml, strings2.xml etc.
I do not mean localized versions of the same file - those multiple files should contain different string ids in the same language, so in code they would be refered like: R.strings1.my_string_1 R.strings1.my_string_2 R.strings2.my_string_3 etc. So, "strings1", "strings2", "strings3" would be a kind of namespace for them.
Or, another way is to have multiple R classes inside one project, which would deal with different stringsXXX.xml files.
Like, currently we can refer to "my.name.space.R" and to "android.R" at the same time, so is it possible to have: android.R my.name.space1.R my.name.space2.R etc
At the same time inside single project?

In Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);
The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};
What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:
private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.
I'm a bit new to Java, Android, and development in general.

Does anybody know of a work around for the android xml file string array inability to process string <item>'s that are not legal java variable names If not, is this not a major bug? Why does an item in an array need to generate a reference id anyway? Isn't this redundant?

I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English.
So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?

That's a lot of code... no time to read it over now.. but off the top of my head: look into either using a database, an Application class (that will run the whole time your app is alive), or adding extras to the Intent bundle before starting your subactivity. These are all methods to pass data around between activities.

I am creating an application which requires login and enables user to configure some settings.
However I would like to enable user to store preferred settings, username and password.
Does anyone know how to store and retrieve values from registry? Another possibility is using SQL Lite database but if possible I would prefer to store values to registry.

Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..
prefs = this.getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);
I didn't have a PreferenceActivity prior to this, but now I do and I am looking to store a few user prefs from this new PreferenceActivity in the same sharedPreferences tag, "MyPrefs".
I know I can access the PreferenceActivity SharedPrefs from my activities via
prefs = PreferenceManager.getDefaultSharedPreferences(this);
but I would like those values saved to my current sharedPreferences tag, "MyPrefs", but I'm not sure how to do this.

I am setting multiple alarms like this, with different values of id. Multiple calls to AlarmManager.setRepeating deliver the same Intent/PendingIntent extra values, but I supplied different ones.
AlarmManager alarms = (AlarmManager)context.getSystemService(
Context.ALARM_SERVICE); Intent i = new Intent(MyReceiver.ACTION_ALARM);
// "com.example.ALARM" i.putExtra(MyReceiver.EXTRA_ID, id);
// "com.example.ID", 2 PendingIntent p = PendingIntent.getBroadcast(context, 0, i, 0);
alarms.setRepeating(AlarmManager.RTC_WAKEUP, nextMillis, 300000, p); // 5 mins
And receiving them like this:
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(ACTION_ALARM)) {
// It's time to sound/show an alarm
final long id = intent.getLongExtra(EXTRA_ID, -1);
The alarm is delivered to my receiver at the right times, but often with EXTRA_ID set to the wrong value: it's a value that I have used at some point, just not the one that I wanted delivered at that particular time.

I've got a database. In its "tags" column, rows can have a combination of multiple values "A, B, C"--such that: row 1 has "A" row 2 has "A, C" row 3 has "B, A" and so on, in various permutations. I am trying to implement search using a managedQuery such that I can return a cursor that contains rows with one or more values in the query. For example, if the user enters "C, A" for a search, s/he should get all rows that have A, C, or A and C. I'm splitting the user query on the comma (",") character, and the final call is as follows (parameters replaced by actual values):
mActivity.managedQuery("content_uri", [id, title, tags], "title LIKE ? OR tags LIKE ?", [%A% OR %C%, %A% OR %C%], "title ASC")
Even though there are rows in the database that contain A, C, or A and C--the managedQuery returns nothing. Thankfully, if the query is for "A", or for "C", the appropriate rows with "A" or "C" or "A and C" are returned. It's just that a query with more than one search term returns nothing. What am I doing wrong here? My guess is that %A% OR %C% is incorrect logic, but why?

Edit: Okay, I found a solution. Don't know that it's the proper solution, but it does work correctly. Added to the code below. I'm trying to allow a user to select a number of directories from a checklist, and return them upon clicking a "Submit" button. Here's a snippet of my code. It populates the List View with all the directories on /sd card/, and for the initial selection (of however many I pick) when I submit, the log shows the correct choices returned. However, if I un check an item, and click "Submit" again, it still shows as if all are selected. Do I need to write a handler to un check an item? I thought that was taken care of by the choice Mode selection?

I have the following code to intantiate a SimpleCursorAdapter to use with a ListView. As you can see I have passed the R.layout.log_item to display the list items, and one value/control to bind to (TripDate).
SimpleCursorAdapter sca = new SimpleCursorAdapter(this, R.layout.log_item,c,new String[] {DBAdapter.KEY_LOG_TRIPDATE},new int[]{R.id.txtTripDate});
This works. I currently only have one widget in the layout xml, a TextView to hold the TripDate.
How do I pass multiple binding parameters for the additional widgets in the layout? So I can also display other info.

I have 2 version of my app, paid/free, and they are not able to access the preferences stored by the library code.
Can someone tell me the right way to store values in SharedPreferences in library code and have the values available to projects that include the library?

Is there a way to access a raw resource file by having its filename in a String? According Google's documentation, I need to use "Resources.openRawResource (R.raw.myDataFile)". This requires that I have the file name at compile time, but what if I have 20 or so files and want to do something to a specific file by passing its file name at runtime?

So my problem is that I've written a function that takes two Doubles, two Int, and a Calendar object on Android (Java). I believe the class provided to allow it to run in a separate thread, AsyncTask, accepts only one type of Object (but allows multiple) as an argument so I figured I might be able to put it in a List or a Linked List or something. Is there such a type that allows multiple data types like that (Double, Double, Int, Int, Calendar), or would I have to create my own object class? I'm a novice programmer so less complicated is probably better, but I'm interested in the best solution as well. What the function does is take a location (double latitude, double longitude), a couple options as integers, and a Calendar Object. It takes the location, options, and date then returns a Time object of the sunrise (or sunset, depending on the options) for that location. and I understand it would probably be best to create a special object class and just pass that, or override the background thread class, but I'm pretty new to object-oriented programming so the less overhead the better (for now). (Update) After a lot of work, it ended up being easier making a data-type class and just using that. The right way turned out to be easier in the end. Who'd a thought.

I've created an application which uses around 15 small audio files. Right now I'm using mp3 files and each is around 200KB. These files are stored in my res/raw directory. I'm using SoundPool class to play the files in my application. I'm hoping to put this application on the android market place. Can one of you suggest what is the best way to store so many audio files? Will my application be scalable? Is wav or ogg format better approach instead of mp3? Please let me know.
