Android :: Creating Strings And Arrays

Sep 29, 2010

I am trying to create a information based application, I have 92 subjects, for these subjects I have 92 map locations and maybe as much as 400 url links. Currently I have created a class for each map location and a class for each url link, but this would mean I would have in excess of 500 classes, so what I want to do is split the subjects in four catergories ie. listview of about 23 in four tabs which I have done and create a class that gets the url based on the selection the use makes and do the same for the map locations.Do I need to put these in a xml using the id method and how do you call individual entries, i.e. would I need 500 Android:id is there an easier way?

Android :: Getting Array From Arrays.xml File

Mar 16, 2010

I am just trying to display a list from an array that I have in my arrays.xml. When I try to run it in the emulator, I get a force close message. If I define the array in the java file (String[] testArray = "one","two","three","etc";) it works, but when I use "String[] testArray = getResources().getStringArray (R.array.testArray); " it doesnt work.Here is my Java file:package;
import android.os.Bundle;
import android.widget.ArrayAdapter;public class Episode7 extends ListActivity { String[] testArray = getResources().getStringArray(R.array.testArray); /** Called when the activity is first created. */

Android :: Preferred Method Of Copying Arrays

Jul 22, 2009

Arrays.copyOfRange() is unavailable in Android, so I'm wondering what the preferred method of copying arrays is. Manually over a loop, or System.arraycopy()? Also, what was the reason behind the decision to not include Arrays.* ?

Jan 1, 2010

I would like to create a list objects called Product (Listproducts).In the application I first have to create the list List products from XML file and then display the products on the map. One product can be located at several locations.Does anyone know what is the most appropriate way to create the structure (a list or linked list) which is the easiest to iterate through and enables to link the lists? The logic should work the following way:

1. Read each point from the list

2. Check which product belongs to the point

3. Display the product informations on the map

Android :: Reading Precomputed Vertex Arrays In Application?

Sep 6, 2010

My app has large vertex arrays that are pre-computed before I even build the app for distribution. I'd like to store these in assets (recognizing the size limits of asset files) and read them in with minimal computation. Can I store them in binary, and just read them into an NIO buffer, and then wrap it for GL, or do I have to go through the whole compute intensive (?) process of reading it in, making a byte array, and converting that to an integer (in this case) array?

Android :: Can Large String Arrays Freeze My Program?

I recently created a program that gets medi-large amounts of xml data and converts it into arrays of Strings, then displays the data.The program works great, but it freezes when it is making the arrays (for around 16 seconds depending on the size).Is there any way I can optimize my program (Alternatives to string arrays etc.)

Dec 13, 2009

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?

Android :: Populating Child List In Expandable Lists Using Dynamic Multidimensional Arrays

Jul 26, 2010

I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.

2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.

Android :: Fast Way To Perform Addition Of Large Float Arrays In Android

Apr 4, 2010

I simply need to add floatArray1 to floatArray2 storing the result in floatArray2.. no third array. all arrays are one dimensional but are very large. probibly as large as the os will let me get away with. Max i would need is two float arrays with 40,000 floats each. but i could get away with 1/10th that i suppose minimum.Would love to do this in 1/30th or 1/60th of a second but that does not seem possible? Also if the code is JNI,NDK or OpenGL ES thats fine. does android have an assembly language or like machine code i could use somehow?

Android :: Caching Large Arrays To SQLite - Java / Android

Jul 28, 2009

Im currently developing a system where the user will end up having large arrays( using android). However the JVM memory is at risk of running out, so in order to prevent this I was thinking of creating a temporary database and store the data in there. However, one of the concerns that comes to me is the SDcard limited by read and write. Also another problem that comes to mind is the overhead of such an operation. Can anyone clear up my concerns, as well as also suggest a possibly good alternative to handling large arrays ( in the end these arrays will be uploaded to a website by writing a csv file and uploading it).

Android :: Passing Variable String To Create Arrays (Android)

May 24, 2010

I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type")But if I try something like getResources().getStringArray (R.array.thelist); it doesn't work.Can someone point me in the right direction? public void list_it(String thelist){String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types);
ListView lv = getListView();

Android :: Writing Arrays Of Parcelables To Parcel In Android

Dec 11, 2009

I'm trying to write an array of objects that implement Parcelable into a Parcel using writeParcelableArray.The objects I'm trying to write are defined (as you'd expect) as:public class Arrival implements Parcelable {All the right stuff in here this class compiles and acts fine And I'm trying to write them into a `Parcel' with: @Override public void writeToParcel(Parcel dest, int flags) I completely don't understand this error message. Parcelable is an interface (not a class) so you can't extend it. Anyone have any ideas? UPDATE: I'm having basically the same problem when putting an ArrayList of Parcelables into an Intent:Intent i = new Intent();i.putParcelableArrayListExtra("locations", (ArrayList< Location> ) locations);Yields: The method putParcelableArrayListExtra(String, ArrayList< ? extends Parcelable >) in the type Intent is not applicable for the arguments (String, ArrayList< Location >)This may be because Location was the class I was working on above (that wraps the Arrivals), but I don't think so.

Android :: Arrays To Be Accessed By Both JAVA & JNI In Android App

Oct 23, 2009

I am facing a problem in my Android app which is calling native functions through JNI. So thought somebody in this group can help me to resolve this. The current code :

1. Create an array in JNI layer ( by NewIntArray()) which can be used by both Java & C.
2.we can name that array as type jintArray array.
3.We call GetIntArrayElements() on this array to get its elements i.e, int * elementsX.
4. This elements would be used by a native call which will set it to some value.(project specific* : may not need interest for this issue)
5. We now get the updated value of elements. And copy it back to array using ReleaseIntArrayElements()
6.We use array in bitmap/canvas class of Java layer to display on screen. The whole procedure is followed for (480x640) times. And so there is a redundant creation of the array for every frame display. Is there any way to avoid this creation of array for each frame. Any better solution to achieve the above? I am not getting a way out of this & the performance of my app has gotten very low too Any JNI code snippets to modify steps (1 to 3 & 5) would be of great help to me.

Media :: Music Player Can't Find All Files / Need Doesn't Use Native Index Of Files?

Apr 4, 2010

I have a Samsung Galaxy I7500 using android 1.5. I extended my phone with a 16GB microSD. I copied a big music collection (around 800 files) into a folder on this SD. Now the problem is that the music player can't find all the files.

I know that there are several threads about android not finding music. The answers are usually that the library hasn't yet been updated or that the ID3 tags are not correct.
I have checked both.

Btw. I can play the files using ASTRO.

In my opinion it seems as if android can't build up a library with too many entries. If I rename the files or put them into different folders, songs disappear and reappear quite randomly.

Do you have any solutions? Is there a music player which doesn't use the native music players index of files?
