Android :: Service Path To Choose For Implementing Large Upload?
Jul 17, 2010
I am trying to implement a RESTful API in which I have to upload files that are relatively large for a mobile platform. The upload could take anywhere from 30 seconds to 5 minutes.I would like my application to be completely usable while the upload takes place. I've been doing some research and I've come across a few methods from which I can't decide which is the correct solution to my problem.Using an IntentService -- handles the worker thread so I don't have to. Using my own type of Service-- still need to implement an AsyncTask to handle the large process. Implement an AsyncTask in a singleton file that would allow me to do all the work there but without using the service class. My question is which method is the best -- if one isn't listed but is a more apt solution to my problem then I would appreciate suggestions.After researching all these methods I am still also confused on one thing. Lets say I upload a 2MB files, but I want to know when it is done. For example, lets say I have a service that uploads an image and returns and imageID -- I need to be able to know when that service returns an imageID -- process that and then move on to the next upload until the rest are finished.

I am writing a application that needs to draw a "route" comprised of lots of GPS points (long+lat). The points are close together and don't follow roads, simply drawing a line between each point is ideal.
The current implementation I have is very slow as I am looping over all the GPS coordinates and creating a new Point and overlayitem in an itemized overlay. This takes around 20 seconds for it to load all of these points and draw them to the mapview. Is there a way in which I can construct a series of lines or point from the GPS coordinates and draw them onto the mapview?
Example of current implementation:

I need to send files as large as 80 MB, but usually in the 15-25 MB several times every day. I use YouSendit, Megaupload and the like on my laptop. Would be a HUGE help if I could simultaneously upload from my Android phone. It has to be able to handle a folder. Basically, a folder full of pictures.

I have done some searching on this problem and the consensus is that there is some sort of a cap on uploading videos to Youtube that are larger than about 10 mb. If you try to upload a larger video Evo then says it is waiting to use WiFi to do the upload. This seems like a Sprint cap to me to prevent their network from having to handle the bandwidth of uploading anything but small videos. (what do we pay the extra $10 for? That's for another discussion.).SO, now that I am rooted, does anyone know how to change the settings and remove the cap so that I can upload larger videos via 3G or 4G without having to use a WiFi connection? I am rooted and on stock 3.29.651.5 Android 2.2. I do not want to use flash a custom ROM just for this ability.

I have a problem with a video that I am trying to upload or share.I can share via facebook or gmail, but am stuck right now because it says that the file is too large.It's about 2 min of video, so I don't know how big that is since I cant find the actual size anywhere.Any idea how I can get it off the phone if I don't have an sd card reader?I guess I could mount the phone to my laptop and copy to my regular comp, but I was hoping there was an easier way to do it?

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

I'm having trouble uploading pictures I've taken on my DX to facebook through the "Quick Upload" option.I got a few uploaded, so I know it works, but now everytime I try, the status bad fills up all the way to "Uploading 100%" then it stalls before giving me the error "Can't send response now.Try again later."I've tried turning Wi-Fi on or off, but on both Wi-Fi and 3G it's not working.Thoughts?

It looks like Android won't natively support in-app purchases for a while, and when it does there might be a huge user base with devices that don't support them.What's the best way to implement iPhone-like (additional content or services) in-app purchases in Android using the Android Market if possible?

I am working on creating an Action Bar like the one from the new Android UI Patterns and I am running into a bit of trouble. I have a ViewSwitcher with two layouts in it. When the user taps the search button I animate between the two layouts. The problem is that the layouts are different sizes and I can't figure out how to make them take up the same amount of space. Here's what I mean. p.s. forgive the bad art, they are just place holders ;)

I am trying to do something similar to that of the android lock screen pattern. I have a class that extends a view that I create multiple instances of. These appear on the screen all at once.
I need to be able to click on them individually and have each one turn green individually, however only one on touch listener is listening at once and it belongs to the last dot which appeared, so if I click anywhere on the screen the last appeared dot turns green no matter where I click.
Here is the code for my dot class:
CODE:......
In the code I called newdotdraw multiple times.

I have 2 apps which should both contain some similar activities.... Now I decided to write a new app, some kind of "framework", which contains these activities, to avoid to write the code twice. How can I use these activities in my other 2 apps ? Whats the common approach for doing this? Adding the "Framework app" to the build path of the two other apps won't work.....

I am adding gesture recognition to my app. I have added the view as described in the Android Developers Gestures article but when it comes to adding:
CODEE:..........
where do I put this in my code, do I have to create a new class for it, or can I have it in an inner class, or does it not need a class at all?! I have a set up similar to Lunar Lander which comprises of two files, one of which is a thread that handles pretty much all the physics and drawing of the game. The other file begins the thread and saveInstanceState method. Furthermore, what type is mLibrary?! I cannot find out anywhere! I imagine I will put the OnGesturePerformed method in my thread as this is where I handle all keyUp and Down events.

I am required to work on an application which is be deployed on devices running Android 1.5. The application is supposed to maintain a connection with a server and regularly poll it for new data. The server will notify the client of new data following which the client will connect to the server and download the data.I know that ideally a push based approach will be more conducive here given that we are to run this on a mobile platform. Also, from Android2.2 there is going to be support for C2DM(Cloud to Cloud device Messaging) but as already mentioned this application is for devices running Android1.5.Implementation: I was thinking of using AlarmManager which would Broadcast Intents periodically(poll interval), The Broadcast receiver will then try to connect to the remote server and make data changed check. If the server has an update, the thread will connect to the remote server and download the data from the server.
Problem and Issues: 1. Is this the right way to approach the problem? 2. Is AlarmManager reliable? Would it remember Alarms after a device boot? (I think it does) 3. How do I ensure that battery usage is kept at minimum.(I have heard something about using "keep-alive" to sustain the session for longer time..what is this legend?) 4. What are other things that I need to consider? I am sure I must be missing lots of things here.

Does anyone have any good references for designing and implementing an idea I have for an android application. My idea is for an application that stores information and reviews about a specific location and presents this information to user.I have gone through all the tutorials and have been reading up on anything and everything about android. Now I am ready to challenge myself with my first app.

I am looking for the implementation of the IAlarmManager.I am interested in the scheduling done by the AlarmManager.setInexactRepeating method and so I started looking for the implementation but I haven't been able to find anything.Internally to AlarmManager, I can see that the actual work is being done by an android.app.IAlarmManager interface.After googling around for a bit there seems to reference to an implementing class called android.app.IAlarmManager.Stub but that is as far I get.I am working with Android 1.6.

I have some design questions that I want to discuss with people interested in helping me. I am planning to develop a simple VoIP program that allows two Android phones in the same network to use VoIP. My goal is simply to capture sound, send the data with UDP, receive UDP data and play sound.My current design is to have 2 threads: one captures the microphone and sends the data; the other one receives bytes and plays them.I was starting to implement that using MediaPlayer and MediaRecorder. The issue that came up is how do I record and play sound? By that, I would like to know if I need to use a file, although that seems slow, or if there is anyway to have the recording automatically sent to my UDP socket please?Basically, I wonder if I have to record to a file, then to be able to play it, or if I could just pass a socket (for recording and playing).

I'm writing an application where real-time knowledge of the GPS state is critical to convey to the user. I request GPS updates at 1000 ms intervals -- when I haven't received another update 1500 ms past the most recent update, I want to display a yellow icon, and 5000 ms after the most recent update I want to display a red icon. Currently, I'm doing it like this: private CountDownTimer gpstimeout; public void onLocationChanged(Location location) { if (gpstimeout != null) gpstimeout.cancel(); gpstimeout = new CountDownTimer(5000, 1500) { public void onTick(long m) { setYellow(); } public void onFinish() { setRed(); } }; gpstimeout.start(); }

The main activity implements the onCreate and OnClickListener as follows:

When I try to run this program on my emulator, after hitting the button, the program stopped unexpectedly. I follow the instructions of implementing OnClickListener firmly so I don't know what's the problem in my implementation.

I am creating a small calendar control that will be part of an application that runs on a larger-than-phone-sized screen. The calendar will simply display the current month and allow users to touch-select a day with an iPhone keyboard style popup bubble indicating which day is chosen.
The problem is that in order to do it with buttons would require 42 tiny buttons, which would probably be a resource hogging solution. Although a keyboard would give me the iPhone-keyboard-bubble-like behavior, i dont think that we can place a keyboard in a static location within a Layout, using it like a View.
So I am wondering what is the best way to go about implementing this. Is my "42 buttons is too many" assumption correct? Is my keyboard assumption correct? Do I have to use a SurfaceView (or something) and draw everything myself? Is there some other grid-like control that can make this simpler?

What are the different ways to implement push technology into your Android app? The client Android app is supposed to receive content (XML Data) pushed by the server. I've looked around and found out it was possible to achieve it with usage off the SOAP protocol. But are there some better ways top implement push? The main concern in this project is the phones battery life, all off it has to happpen over WiFi, pushed content has to be viewable on the device immediately.
