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.* ?

I've been trying to find a way to upload a video from an Android device to an API, but I haven't found a good way to do it. It seems most of the information I've found online is fairly out of date (a lot of it being from last year). Most of them are using a method like this: http://getablogger.blogspot.com/2008/01/android-how-to-post-file-to-php-server.html

View 1 Replies View RelatedI 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?
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 com.xtensivearts.episode.seven;
import android.app.ListActivity;
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. */
Okay I am using the Sprint Hero and am looking for a different browser. I currently use Dolphin, and I like it, but my main complaint is that if I save a bookmark with it, it doesn't go to the same bookmark list as my widget. That is one feature I would like the browser to have, though that may only be on the default one. I do like that you can download Youtube videos with Dolphin. I know there are a few others, such as Opera and Steel. Which do you suggest, knowing the things I like to do with my browser?
View 40 Replies View RelatedI 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
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?

View 1 Replies View RelatedThe documentation for sendOrderedBroadcast() describes the function as following: "Broadcast the given intent to all interested BroadcastReceivers, delivering them one at a time to allow more preferred receivers to consume the broadcast before it is delivered to less preferred receivers."
How do we specify which receiver is preferred, such that the preferred receiver gets the first shot at handling the intent?
To illustrate, say I have 2 possible activities, ActivityA and ActivityB, to handle them intent. If both are alive, I would like ActivityA to always handle the intent in favor of ActivityB.
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?

In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition.

View 9 Replies View RelatedI've been trying to find out how to create an intent that will open the user's preferred browser without specifying the URL. I know how to open it by giving a specific URL like this:Intent intent = new Intent();intent.setAction(Intent.ACTION_VIEW); intent.setData (android.net.Uri.parse ("http://www.google.com")) ;context.startActivity (intent);I don't want to open the browser to any page in particular, just the set homepage or whatever page the user was on last. I've thought about looking up the homepage set within the app but you can't do it with the default Browser app because it is private. Does anybody know of a way to do this?

View 4 Replies View RelatedI 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.
In terms of efficiency, is it better to use arrays programmatically or through calls to xml files.
I'd prefer to use xmls for organisational reasons, but is there much of a performance hit.
I'm trying to have my home-screen application register itself as the default home-screen so the user is not prompted with the IntentResolver's list of all the available home-activities.
This is my code:
CODE:.................
I have the android.permission.SET_PREFERRED_APPLICATIONS set in the manifest. After executing the code above, the logs claim things have been added like expected (same logs as when I tick off "Make default" from IntentResolver's list). However, when I proceed by clicking home, the list still shows up and the logs say:
CODE:.....................
So it seems the resolver deletes the default entry. Am I doing something wrong, or is this a security measure? What are the ideas behind this?
I am sure this is old but, I downloaded Handcent at least 10 times already. I like the customization. It's the best SMS Application to me, but I'm not sure if it makes my phone run a bit laggy. I always go back to the stock app even tho its kind of boring, but very fast. I guess the question is, Is Handcent really worth it to you?
View 5 Replies View RelatedI made a remote starter, keyless entry, and window roll down module out of a Linksys router. It serves up a webpage that I access from my Android through WIFI connected directly to the router. I just have to be within WIFI range to operate it. It works flawlessly. No actual internet involved.
Here is what I would like to do: Create an app that accesses each webpage to control it. I am thinking webview, but I don't ever want to see the actual web page. The app just needs to open the page in the background to make the control work. The current hassle is that I have to go to my WIFI settings and select the router. Use the control and then set my WIFI back to the original connection. Is there a way to have the phone automatically connect to the router associated with this app upon app initialization and then have it return the WIFI setting to the previous state after the app is closed?
I'm using a Legend atm- and I'm thinking of getting the Desire/Galaxy S, but I'm not sure how I can copy back over my contacts from my Phone to my SIM card.When I first got the phone I copied over my contacts from my SIM to my phone and then cleared out the SIM card- but now I don't get an option from People to Export to SIM card, but I get the option to Export to SD. Having done so I'm not sure if I did it properly because there also isn't an option under View to see info from the SD card- only from Google, Phone and SIM.I really can't be bothered getting an app for this lol. I don't really want to do Google Sync because it isn't exactly as re-assuring as having the info in a SD/SIM card you can hold.So really how do I copy over my contacts from Phone to SIM/Phone to SD Card? And how can I check to see if I've done so properly (I will uncheck Phone from the View menu in People)?Also- how to move all my SMS's from my Phone to SIM/Phone to SD as well?
View 2 Replies View RelatedI 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?
View 1 Replies View RelatedIm 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).
