Is there a way to programmatically set a proxy server in my Android App?

All other Apps on the device should not be affected by this proxy settings.

HTC Incredible :: Downloading Applications Via WiFi - Server Error Occurred?

Jun 25, 2010

I just got HTC Incredible, but am still using my blackberry storm and need to for another week or so - do not want to convert prior to the company moving to google mail. Anyhow, I managed to skip the activation and am playing with the phone on WiFi only - problem - I would love to play with some apps, but cannot figure how to get them to my phone! Googling it did not help me, and all I can see is what the apps are, not how to download them. Going into the "Market" app gives me "A server error occurred".

How the heck can I get some apps and play more with the phone prior to activating with Verizon. So far I am rather impressed with this device! Seems like the hardware/OS works very nice! Browsing, doing email some other things over WiFi is blazing fast, and in general the phone interface seems very nice and intuitive! Way better than by BB Storm! Sorry if the answers are out there - I just did not manage to find the right ones.

Android :: Creating Layout File Programmatically

Android :: Better To Create Db / Tables Programmatically - Through A .db File In Assets?

Mar 2, 2010

Does Android have a "best practices" guideline on creating & populating the db/tables programmatically vs. deploying a .db file in assets?

What are the pros/cons of both approaches?

I have a db with big long strings in several columns, and about 50 rows, so writing the insert statements alone would take quite some space. It seems a waste.

Android :: Get The Size Of File Before Downloading?

Jun 6, 2010

I have to download a file and I'm using this code, which is basically an AsyncTask that is meant to update a progress bar. But, since I don't know what's the file size I've been having to use the spinner progress bar. So, how can I get the file size before start downloading it so that I can use a normal progress bar?

Android :: Open Apk File After Downloading For Auto Update?

Aug 25, 2010

I have an application that I'd like to add auto-update functionality (its not in the marketplace). I have all the code in place that would check to see if there is an update available and then i call something like this: Intent intent = new Intent(Intent.ACTION_VIEW ,Uri.parse(Configuration.APK_URL)); c.startActivity(intent); which starts downloading the file, although is there a way that I can programatically tell it to "open" the file to begin the installation process without the user having to go to the downloads and clicking on it?

PNG File Not Display In Image View When SRC Set Programmatically

Jun 8, 2012

I have a png file in my res/drawable-ldpi folder. I'm working in Eclipse with the emulator, but I've tried this on my 2.2.1 Android phone and I get the same behavior. I have an ImageView and I want to set the src programatically, based on a database call. If I just put

Code:

src="@drawable.norusdpyr"
in the Activity's XML file, the file displays fine. BUT, if I put

Code:

String imageresource = "R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
where parsedData[4].toString() = "nor_usdpyr" I don't see anything. I've also tried

Code:
String imageresource = "android.resource://" + getPackageName() + "/R.drawable." + parsedData[4].toString();
chart.setImageURI(Uri.parse(imageresource));
and

Code:

InputStream is = getClass().getResourceAsStream("/drawable/" + parsedData[4].toString());
chart.setImageDrawable(Drawable.createFromStream(is, ""));
and

Code:

String imageresource = "R.drawable." + parsedData[4].toString();
File file = new File(imageresource);
chart.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath()));
and

Code:

Context context = getApplicationContext();
int ResID = context.getResources().getIdentifier(imageresource, "drawable", "com.KnitCard.project");
chart.setImageResource(ResID);
finally,

Code:

chart.setImageURI(Uri.parse("android.resource://" + getPackageName() + "/R.drawable.nor_usdpyr"));
doesn't work.

None of these work. What am I doing wrong?

Android :: Best Practice For Downloading File - URLConnection - HttpClient - Intent

Mar 11, 2010

If an app needs to download some critical data (without the data it cannot function) of several MB, what is the best practice? The app would start, a prompt would be shown to confirm download, download would commence, and the user would be prevented from going further until the download successfully completes. I don't expect the download would take more than, say, 10 secs over wifi but, of course, would take much longer over 2G. Is a service absolutely essential for this? Maybe there is already some code out there that takes a URL, downloads it in a service, and broadcasts a configurable Intent when the download has completed?

Android :: Custom Changeable Handler When Service Finishes Downloading File

May 30, 2010

I have a Service that downloads a file from the internet. What I want is for the response (an InputStream in this case) to be handled by a custom handler that can be switched (like a strategy pattern) but I can't figure out how to do this. So basically the User of the API would be able to plug in different handlers for the response, some would parse XML, others might save files etc. I realise I could pass through the activity context and execute the method from this (given some interface) but I don't want to do this obviously, in case the Activity is closed in the meantime while the file is still downloaded.

UPDATE - I just had one idea it will work sort of but has problem if the DownloadRunnable gets changed between executions of the downloads.

The modified Runnable interface
interface DownloadRunnable {
void run(InputStream stream);
}

An enum

public enum ServiceHandler {.......................

Android :: Make SAX Parser Wait For File To Finish Downloading Before Parsing?

Sep 20, 2010

I am having a problem where my XML files are slow to load and don't finish downloading before they start to be parsed which throws an xml not well formatted exception from my parser showing that the file downloaded incompletely. The complete error from logcat is "ERROR/Error(323): errororg.apache.harmony.xml.ExpatParser$ParseException: At line 10, column 46: not well-formed (invalid token)" I know the xml file is correct because sometimes it will work and I can also pull it up in my browser and look at it.

What would be the best way to make the parser wait for the InputSource before continuing on and parsing the xml data? The code below is the code I use to get the file and parse it.

SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser sp = spf.newSAXParser();
XMLReader xr = sp.getXMLReader();
GradeHandler gradeHandler = new GradeHandler();
xr.setContentHandler(gradeHandler);
URL url = new URL("https://url/to/xml/file");
HttpsURLConnection ucon = (HttpsURLConnection)url.openConnection();
ucon.setHostnameVerifier(new AllowAllHostnameVerifier());
xr.parse(new InputSource(new BufferedInputStream(ucon.getInputStream())));

HTC EVO 4G :: Data Time Out - Downloading File From Android Marketplace Surfing Web Watching Using GPS?

Jun 25, 2010

I have been having some major problems with my EVO regarding the data. If I use anything that is on the heavy side of bandwidth, like downloading a file from android marketplace, surfing the web, watching sprint tv, using the GPS, etc...the data will just time out for about 3 min at a time. For instance if I am downloading a 5mb app from android marketplace, it will maybe download a megabyte, then it will just stop downloading. If you look at the 3G symbol at the top, it will be white, but only the upstream indicator will be on. I can then open any other internet application on the phone, and nothing will work. It usually lasts for about 3 minutes at a time and happens fairly regularly. It will end up taking me 15-20 min to download a 5mb file from the marketplace. Same thing if I browse a bandwidth heavy site like digg.com. It will just time out after a while and it will just show the upstream indicator as solid and not do anything in any program.

This problem is not location dependent. I have this issue at my apartment, at work, at my friend's house, at the Sprint store...anywhere. I live in South Denver.

In chronological order, this is what I have done to troubleshoot/fix the problem:

First noticed problem
Turned off phone/Turned back on
Rooted and installed custom version of 2.1 w/ Sense
Removed battery (power cycle)
Talk to Sprint cust care. They sent signal over that reactivated the phone (2x)
Did factory reset on phone and formatted SD card
Swapped phone at Sprint store with new one

So even after swapping my EVO with a new EVO from the Sprint store and not fooling with the phone at all, I am still having the same exact issue.

I am absolutely at wit's end with this and I have no idea what to do at this point.

Update (6/25):

I have not been able to test with Wifi yet, but I just had one of my coworkers that has the same phone to replicate the issue on his phone. He is having the same exact problem as me, he just didnt realize it.

We set our phones next to each other and downloaded Space Buster 3D Lite off the Android Marketplace. Mine crapped out about 2mb in and so did his. He wasnt able to surf or do anything else on his phone for a few minutes just like mine.

I'm wondering if this a network problem in our area or if there is a problem with the phone.

Also, I downloaded a continuous ping program and did 3,000 pings with no packet loss, so it seems to only happen with heavy data usage ie. saturating your bandwidth.
