I seem to be having a weird issue when parsing XML from a server. In LogCat the following warning is displayed:08-31 12:05:28.870: WARN/ExpatReader(2031): DTD handlers aren't supported.The parser then seems to stop. I can't figure out what is causing this problem, my approach doesn't seem any different in this instance with regard to parsing XML. Does anyone have any recommendations to fixing this issue?

I need to parse an UTF-8 encoded input stream, so I think the most appropriate method is to use
CODE:..............
For that I need to import org.apache.harmony.xml.ExpatReader but I cannot figure out how, I mean which Java package must I install from http://harmony.apache.org/download.cgi?
Or is there an alternative method to accomplish the same goal?
I want to create multiple handlers that gets triggered based on users selection, but this handlers implement the same runnable method. the only difference is that they call different postDelayed() method. how do i go about achieving this without rewriting the same code for the runnable? i am still not clear about how the handleMessages() works and if it can be used for this?

View 2 Replies View RelatedWhich is the way to attach the custom event handlers for the activities, in case they support one, when the activity is started using Intent and startActivity() methods. Does intent has a special way to take up the handler callback references. Basically, I wish to handle call end activity after invoking the call activity.
View 2 Replies View RelatedI've more than one Handlers in an Activity. I create all the handlers in the onCreate() of the main activity. My understanding is the handleMessage() method of each handler will never be called at the same time because all messages are put in the same queue (the Activity thread MessageQueue). Therefore, they will be executed in the order in which are put into the Queue. They will also be executed in the main activity thread. Is this correct ? Code...

This question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnable. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ?
I'm new to Android.My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data).
My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide.
I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method.The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this.
I am writing an Application that has multiple layouts with buttons. I have set up onClickListners for the buttons. Some buttons will change the activity and bring up a new layout with new buttons, and others will send outgoing SPP strings over Bluetooth. The strings will be defined in an XML file and will not change (serial commands).I can hard code the MAC address of the Bluetooth Server and only need to send data, not receive.
I am looking for some general guidance on the direction to go as far as setting up my Bluetooth connection and outgoing transmissions. I have looked at the BluetoothChat example extensively but do not have any good resources in the case of multiple activities.
-Do I use a separate activity to manage all Bluetooth transmissions and connections and create handlers for every case where I would send a Bluetooth message?
-Should I add Bluetooth connection+transmission threads in every activity (seems like i would run into issues losing the connection when changing activities)?
-Can I use handlers that are not class specific where the BluetoothService Activity could send whatever was prompted by the active/current activity?
-Could I just hard code all strings to be sent in the BluetoothService Activity and the UI activity could prompt the BluetoothService Activity to send the requested string based on the button click?
In an HTML page, I have at one place, <a name="updates"></a>, but in a WebView, when I click on <a href="#updates">updates</a>, it doesn't jump to the correct place. It works fine if I load that page in a browser. It does nothing but mark that link as visited in the WebView. Is there some setting that I'm not correctly configuring?

View 2 Replies View RelatedThis one surely is a simple one but I haven't made sense of is yet. I'm working on an app in opengl es on android. everything goes well except when I load the textures. I manage to open load and create all the textures without any problem, but the image displays itself rotated of 90. it looks as if the application does not consider that its is in landscape when opening the image...I solved the problem by turning all my textures of 90 degrees but I would sure like to figure this one out Because it is the only thing that is not rotated, the top bar is rotated, the touch coordinated are rotated,
the h and w of the surface are good,
Here are some code snippets that I think are relevant:

I've been developing Android application for quite awhile now. Please correct me if I'm wrong, but as far as I know the UI toolkit and 2D graphics API aren't hardware accelerated (the official documentation states that Canvas is not accelerated). I've found that most non- trivial animation or blending operations are painfully slow even on mid-level devices like a Droid, even after taking much time to optimize my code.
I'd like to know what the rationale is for not providing hardware support for these frameworks? Wouldn't it be possible to at least make it optional for vendors to implement support? Does anyone have any additional information about this issue?
How can I show pictures in WebView without saving images into file system?
I have tried to implement my custom Content Provider, but method openFile returns ParcelFileDescriptor that points into filesystem (or socket). My pictures are in filesystem, but in encrypted form.
I have tried also URL.setURLStreamHandlerFactory, but in android java it is useless (because custom streamHandler can be register in jvm that is not allowed). I also try html code "img src="data:image.gif;base64,R0lGODlhiAAkAMQAANOOk...", but in embedded chrome it's not working.
i`ve got some problems with finish() method. I expect what after calling on my Activity finish() method onStop and onDestroy must be triggered(or am wrong??), in majority of examples they are, but Scenario: - reboot phone - launch activity - invoke finish() onPause is triggered but afterwards they are no calls to onStop() and onDestroy()I`ve noticed, that those calls are triggered after launching any other activity.
View 7 Replies View RelatedI'm trying to set the background of a RelativeLayout to a particular color. However, the color that's being displayed by the emulator and by the device is off by quite a bit.However, when I view the that layout in the emulator, the color I get back (using xScope on Snow Leopard to get the pixel values) is #e7e7ef, which looks a bit purpley.Looking at the view on the G1 also looks a bit off from what I want. If I take a screenshot of the G1 using the debugger and examine the pixels, they too are #e7e7ef.

When I search on the market for a specific application, say "shazam", I get a message;
Suggestion
- Make sure all words are spelled correctly
- Try other keywords
- Try less specific keywords
However in the top bar it says
"1 result for Shazam"
But the result isn't showed. I have this problem with up to 9 search results.
I'm using a HTC Hero. Any suggestions on this one?
We've been developing an Android app at work for a few months now and recently acquired Droid Incredibles (API ver. 8) to replace our HTC Dev Phones (API ver. 4).
DANG are these some sweet new toys, but unsurprisingly, they've got a few quirks...
1) It's normal for my user to let the program run for long periods without any input, but he'd still need the display to work the entire time. Can anybody suggest a function call or setting or something that will prevent the Incredible's screen from dimming while my application is running??
2) On the Dev phone, I was able to copy my application's database file (thousands of uses, that) onto the SD card's root directory and fly. I could view the directory on my PC via USB; when I released the SD card from the PC, my application was perfectly happy with it and obediently read from and wrote to the database; and I didn't have to remove the SD card, ever. That doesn't seem to be the case with the newer, better phone, though. My application seems to be reading my start up parameters properly, but all attempts to save data in my database aren't working so well unless I'm just doing something wrong. Can anybody point me to documentation specifically geared toward the Incredible?
When using a View within a View, for example an ImageView within a LinearLayout, both of which have xml drawable resources (the LinearLayout as a background) specifying PNG drawables to use for the on/off states, shouldn't children Views receive the focus state when their parent gets focus? So as far as I understand, both my LinearLayout and ImageView should be switching to their focus states right? Apparently not Or, more likely, apparently my implementation is incorrect.
The focus state works on the LinearLayout but my ImageView never receives focus.. I have both Views set to android:focusable="true".

I had to get my Evo replaced today and I used ASTRO and MyBackup Pro to backup my apps to my SD Card. After installing them onto my new Evo, I went to the Market and then to Downloads, and they don't show up there. How am I suppose to know when I will have an update?

My sister changed her Facebook photo, I use the facebook photos as the contact photos on my phone. My phone has not reflected the different photo yet, its been a few days.
I've unlinked and relinked the account, went into Accounts & Sync, and re-synced it, but the old photo still shows up. It's not a huge deal, but the photo is her and her ex-boyfriend, and I'm sure she'd rather me not have that photo on my phone.
So I'm trying to make Google play music save on my sdcard and I'm having a problem with the script. First the phone I have is the DROID RAZR MAXX and I just did a FDR because of a root problem and now that I have it rooted the scripts aren't working. My script text is this
"Mount -o bind sdcard-ext/MusicCache sdcard/Android/data/com.google.Android.music"
The error it shows is like this:
exec sh '/mnt/sdcard/MusicScript.txt'
card/MusicScript.txt'
/mnt/sdcard/MusicScript.txt[2]: Mount: not found
"generic network failure" continually keeps me from getting and sending pics in handcent. What's the deal? They won't work in the HTC message app either.But when I first got the phone last Tuesday I received a pic from girlfriend just fine.Not sure what to do here.Anybody have any suggestions? Similar problems?
