| ostaski | has entered the room |
| Mark M. | Welcome, Student8080! |
| Mark M. | And, welcome, ostaski! |
| Student8080 | Hi Mark! =) |
| ostaski | Howdy Mark, how's trix? |
| Mark M. | Oy |
| Mark M. | Ever hear the expression "having the tiger by the tail"? |
| ostaski | that's good, right? :) |
| Mark M. | Depends on how big the tiger is and how fast it moves |
| Bhavyank | has entered the room |
| Mark M. | Right now, I feel like I'm on the underside of Tigger, and being bounced upon repeatedly |
| Mark M. | Welcome, Bhavyank! |
| ostaski | watch the teeth. |
| Bhavyank | Hey Mark! how are you? |
| Mark M. | Yes, they are sharp and pointy |
| Mark M. | I'm a wee bit frazzled, but otherwise OK. |
| ostaski | the weekend is only ... 3 days away |
| Bhavyank | what did i miss here?? |
| Mark M. | Hmmmm...I know not this "weekend" of which you speak. |
| Nov 10 | 8:00 PM |
| Mark M. | Bhavyank: |
| Mark M. | oops |
| Mark M. | @bhavyahk: haven't missed anything yet |
| Mark M. | So, anyone have any Android dev questions |
| Mark M. | ? |
| Bhavyank | great!! Yeah! if ostaski is in the middle of asking..i will take the next turn |
| ostaski | I'm picking up where I left off last week ... got sidetracked |
| ostaski | can you look at: http://groups.google.com/group/android-beg… |
| ostaski | didn't get any takers |
| Mark M. | yeah, my problem is that I'm being moderated on -beginners right now |
| Mark M. | I don't answer much there at the moment |
| Mark M. | cotton-pickin' spammers |
| ostaski | no problem ... didn't want to cross post |
| Mark M. | I suspect you'll need a wildcard in your intent filter |
| Mark M. | I think that if the intent specifies a MIME type, you may have to match it |
| Mark M. | No, wait |
| Nov 10 | 8:05 PM |
| Mark M. | OK, so your activity runs, but when you try invoking the MmsSender logic, you blow up trying to send the MMS, right? |
| ostaski | right |
| ostaski | No Activity found to handle Intent |
| Mark M. | Have you tried a concrete MIME type instead of image/* in your setType() call? |
| Mark M. | Take a look at http://www.androidsnippets.org/snippets/101/ |
| ostaski | yes, I tried: sendIntent.setType("image/jepg"); first |
| ostaski | typo this time around |
| Mark M. | Presumably you mean image/jpeg |
| ostaski | yes |
| Mark M. | What happened then? |
| ostaski | same error |
| Mark M. | The snippet I linked to does not have a subject extra |
| Mark M. | That's the biggest difference I see |
| ostaski | not sure where I got that, but it included the comment |
| ostaski | |
| Nov 10 | 8:10 PM |
| ostaski | I can try without the subject extra |
| Mark M. | The
other possibility, which would be somewhat screwy, is if you can't use
a SD-card image but have to grab one out of the media store, per that
snippet |
| Mark M. | Oh, oops |
| Mark M. | Big difference in the action |
| Mark M. | snippet has ACTION_SEND, you have ACTION_SENDTO |
| ostaski | right, I'm trying to do this w/o user interaction |
| Mark M. | Ah, right |
| Mark M. | might not be possible |
| Mark M. | I'd
try getting it working with ACTION_SEND first, to make sure the rest of
the Intent is working properly, then switch to ACTION_SENDTO |
| Mark M. | If you get the same error (No Activity found to handle Intent), then you're just out of luck, I suspect |
| ostaski | figures ... running w/o subject extra now |
| ostaski | how you say ... Oy |
| Mark M. | While you experiment...Bhavyank, did you have a question? |
| Nov 10 | 8:15 PM |
| Student8080 | has left the room |
| Bhavyank | yup |
| Bhavyank | I am trying to |
| ostaski | same error ... I'll defer to Bhavyank |
| Bhavyank | load the images with AsyncTask and when i am trying to actually load it ..I get this particular error everytime |
| Bhavyank | skia D --- decoder->decode returned false. |
| Bhavyank | and I never get the image loaded |
| Mark M. | When you say "load the images", what do you mean? |
| Bhavyank | ohh ok..Let me be more specific. I have an ImageView as a place holder in my activity |
| Bhavyank | I
have the visibility as invisible in the beginning and based on the
activity context i have to set the image from one specific url |
| Bhavyank | to that imageview and turn the visibility of that imageview to visible |
| Mark M. | OK |
| Bhavyank | so i just used the following code: |
| Bhavyank | View paste
|
| Nov 10 | 8:20 PM |
| Mark M. | Urk |
| Mark M. | And you're doing this in what method in the AsyncTask? |
| Bhavyank | onpostexecute |
| DeltaDroid | has entered the room |
| Mark M. | OK.
You might want to split that logic up so that the bitmap-loading is
being done in doInBackground(), but that is probably not the source of
your error. |
| Mark M. | Let me guess -- your error occurs on the BitmapFactory.decodeStream() call, right? |
| DeltaDroid | hello all |
| Bhavyank | yup |
| Mark M. | Howdy, DeltaDroid! |
| Mark M. | I'm not a huge fan of decoding the bitmap straight off of a URLConnection -- that always made me nervous. |
| DeltaDroid | hi Mark |
| Bhavyank | actually i used one of your Bus module and implemented my own CachedImageLoader as well |
| Mark M. | OK |
| Bhavyank | still i got the same error |
| DeltaDroid | I'm total newbie so forgive my questions |
| Mark M. | If
you look at the image loading code I have (there and in the Thumbnail
stuff), I use HttpClient and download the whole byte array, then create
a Bitmap from there. |
| Mark M. | DeltaDroid: no problem |
| Mark M. | Bhavyank:
part of the reason for that is so my data loading can be done in
doInBackground() -- your code as it stands does the data loading in
onPostExecute(), which is on the UI thread |
| Nov 10 | 8:25 PM |
| Bhavyank | yeah..But i wanted to set the visibility to visible after the image is loaded.. |
| Bhavyank | so i put the logic in onPostExecute() |
| Mark M. | Bhavyank: you would still put the image in the ImageView and make it visible in onPostExecute() |
| Mark M. | However, the actual loading of the image off the URL would be done in doInBackground() |
| Mark M. | After all, you have no idea how long that might take, given Internet connection speeds and such. |
| Mark M. | Here in semi-rural Pennsylvania, I don't have 3G -- more like 0.72G, so downloads of anything take time. |
| DeltaDroid | I
have been able to run "hello world" on Android 2.0 using eclipse on
vista but its super slow and inconsistent what are my options for speed? |
| Bhavyank | got it |
| Mark M. | DeltaDroid: #1 = keep your emulator open |
| Mark M. | #2 = get more RAM (Eclipse + emulator + Vista is gonna be big) |
| Mark M. | What are the specs of your development PC? |
| Mark M. | (by specs, I mean amount of RAM and speed of the CPU) |
| Nov 10 | 8:30 PM |
| Mark M. | ostaski: you said you got the same error -- did you try ACTION_SEND? |
| ostaski | just tried with ACTION_SEND and get the SMS dialog ... bombs with |
| ostaski | Transactiojava.io.IOException: Cannot establish route for http://mms.msg.eng.t-mobile.n(651): com/mms/wapenc: Unknown host |
| DeltaDroid | just a minute |
| ostaski | probably an emulator thing? |
| Mark M. | Oh, yeah, I would suspect an emulator would have a trifle bit of trouble sending an MMS |
| ostaski | I'll try on my G1, but not now. |
| Mark M. | A bit surprised the error is that cryptic-looking |
| Mark M. | But, regardless, you're definitely past the no-activity-found error when using ACTION_SEND |
| Mark M. | If you substitute in ACTION_SENDTO now, you get the no-activity-found error? |
| DeltaDroid | 4G ram /intel celeron 1.73GHz |
| Mark M. | DeltaDroid: the RAM is fine, the CPU is not |
| Mark M. | I would expect that to crawl |
| DeltaDroid | it crawls |
| DeltaDroid | is a physical phone like tmobile pulse a good test phone? |
| Nov 10 | 8:35 PM |
| Mark M. | I don't know much about the Pulse -- it's not available in the US AFAIK |
| Mark M. | Most Android phones are fine for development |
| ostaski | tried again with ACTION_SENDTO and get the same error as before ... No Activity found to handle Intent |
| Mark M. | ostaski: yup, you're screwed |
| DeltaDroid | lol |
| Mark M. | must be the SMS/MMS activity doesn't have a filter for ACTION_SENDTO, just ACTION_SEND |
| Mark M. | at least for the MMS case |
| ostaski | Oy |
| Mark M. | you could try looking at the source code and seeing if there's a way to reuse some of it |
| Mark M. | I think the Messaging app is open source, though I haven't really looked for it |
| ostaski | good idea; I'll try that. Thanks! |
| Mark M. | Worst-case, you'll have fodder for a feature request |
| Mark M. | it might be that it sends MMS using APIs not in the SDK, only available to firmware apps |
| Mark M. | but, you could petition for them to open those up or support ACTION_SENDTO |
| ostaski | Guess we'll know soon enough. :) |
| Nov 10 | 8:40 PM |
| ostaski | Android doesn't seem to like stuff being done w/o user interaction ... probably a good idea, but makes this app a bear to build. |
| DeltaDroid | can I get an idea of what guys are building on ?I think I need to go shopping before |
| DeltaDroid | I can really start |
| Mark M. | DeltaDroid: well, my main rig is a quad-core, but that's decidedly overpowered for what you need |
| Mark M. | I'd think a decent dual-core would suffice, with the RAM you have |
| Mark M. | Of course, I don't use Eclipse... |
| Bhavyank | Mark, I did what u said |
| ostaski | FWIW, I've got a dual core 2.13 GHz with 2 GB ram |
| Bhavyank | and I still get the same error |
| ostaski | xp |
| Mark M. | Bhavyank: using HTTPClient? |
| Bhavyank | nope..i copy pased code from |
| Bhavyank | |
| Bhavyank | URLConnection
connection=new URL(url).openConnection(); InputStream
stream=connection.getInputStream(); BufferedInputStream in=new
BufferedInputStream(stream); ByteArrayOutputStream out=new
ByteArrayOutputStream(10240); int read; byte[] b=new byte[4096]; while
((read = in.read(b)) != -1) { out.write(b, 0, read); } out.flush();
out.close(); byte[] raw=out.toByteArray(); put(url, new
BitmapDrawable(new ByteArrayInputStream(raw))); |
| Mark M. | Ah, OK. Forgot I used URLConnection there, but it still reads the whole thing in. |
| Mark M. | What is the full text of the error message? |
| Bhavyank | skia D --- decoder->decode returned false. |
| Nov 10 | 8:45 PM |
| Bhavyank | it comes in the middle of my logging |
| DeltaDroid | whats the eclipse substitute and why not eclipse |
| Mark M. | Bhavyank:
try writing the byte array out to a file, perhaps on the SD card, then
examining it to see if you are getting the same file downloaded as you
would expect |
| Bhavyank | ohh ok.. |
| Bhavyank | thats a good suggestion..but i have one more question |
| ostaski | DeltaDroid: I run eclipse 3.4 ... no problem on xp |
| Bhavyank | if others don't have any problem |
| Mark M. | DeltaDroid:
why not Eclipse? Partly, it has only been in the past year that I had a
rig that could handle it. Mostly, it's because IDEs get in my way. |
| ostaski | go for it, Bhavyank |
| Bhavyank | thanks guys |
| Bhavyank | I
am in the situation where: I need to present the login page in the
middle of the application flow. But I don't want to show the login page
again, when user preses the Back Button |
| Bhavyank | when i say page, i meant activity |
| Bhavyank | Is there any way to do that. When u press Back, you can skip specific activity and go to the one before that? |
| Mark M. | Bhavyank: is the destination after the login activity always the same? |
| Nov 10 | 8:50 PM |
| Bhavyank | right now it is |
| Bhavyank | but i can see that in few weeks..it will be either or ..for two activities |
| Mark M. | Phooey |
| Mark M. | I was going to say you could make the login not be an activity, but just something that's part of the destination. |
| Mark M. | One trick that I know has been used works something like this: |
| Mark M. | Step
#1: Set a boolean flag in your login activity (e.g., hasLoggedIn) to
true right before calling startActivity() on the destination. |
| Mark M. | Step #2: in onResume() of your login activity, if hasLoggedIn is true, immediately call finish(). |
| Mark M. | Step #3: there is no step #3 |
| Bhavyank | aah! |
| Mark M. | That will give the desired flow, though I'm not sure if the login activity will briefly flash on-screen or not |
| Bhavyank | and will that take me to the activity before the login |
| Bhavyank | ? |
| Mark M. | Yes, finish() is the Java equivalent of the user pressing the BACK button |
| Bhavyank | it is essetially two back button at once then? |
| Mark M. | More or less, yes |
| Bhavyank | ohh ok.. |
| Bhavyank | is there any way to listen to back button |
| Bhavyank | and put our own intent in the listener? for startActivity? |
| Mark M. | Oh, I *really* wouldn't do that. |
| DeltaDroid | how quickly can i transition my c# knowledge to java and whats the best way |
| Mark M. | How does the user ever leave your app, except via HOME, then? |
| Nov 10 | 8:55 PM |
| Mark M. | DeltaDroid: depends. Do you watch Dollhouse? |
| Mark M. | ;-) |
| Bhavyank | yeah..I see your point |
| Mark M. | Bhavyank:
you can listen to BACK by overriding onKeyPreIme() in a View (and maybe
in an Activity), but I would not start a new activity then -- that
could get messy |
| DeltaDroid | no what is it ? wait let me google it |
| Mark M. | DeltaDroid: more seriously, you might consider _Head First Java_ or another book |
| ostaski | DeltaDroid: check out Thinking In Java - http://www.mindview.net/Books/TIJ/ |
| Mark M. | don't worry about the Dollhouse reference, just a bad joke |
| DeltaDroid | lol |
| Mark M. | yeah, there's also a Wikibook on Java development and umpteen gazillion online tutorials |
| ostaski | I'll need to google dollhouse. :) |
| Bhavyank | ohh ok.. |
| Bhavyank | Has anybody has luck to run the apps on droid? |
| Mark M. | I learned Java back when wooly mammoths roamed North America, so I haven't used any recent resources |
| DeltaDroid | ostaki:hahaa |
| Mark M. | Bhavyank: picked up a DROID last night for testing, haven't had a chance to try any apps on it yet |
| Mark M. | If you are near where Google's having one of their Android Developer Labs this month, they'll have DROIDs available |
| Bhavyank | ohh ok..I fear that I may run into layout issues |
| Bhavyank | with higher resolution..i checked romanguy's |
| Mark M. | That sort of thing you should be able to test via the emulator |
| DeltaDroid | I tried to get in but they said it was full |
| Bhavyank | guidelines |
| Nov 10 | 9:00 PM |
| Bhavyank | yeah..i can go 854 resoution in emulator..but it just makes the emulator screen big..i am not sure about density of the screen |
| ostaski | Mark, looks like time's up ... will you being doing this again next week? |
| Mark M. | there's
a -scale option you can pass, or if you can run outside of Eclipse,
just run the android command, bring up the AVD Manager, and it'll give
you a dialog to help you compute the right values. |
| Mark M. | ostaski: yup, time's up |
| Mark M. | Yes, I'll have another office hours next week, same time. |
| Mark M. | I won't have one Thursday morning, though, as I have an online training session scheduled that I need to teach |
| ostaski | great, "see" you then ... over & out |
| ostaski | has left the room |
| Bhavyank | Thanks Mark, |
| DeltaDroid | thanks a lot had fun learn a lt |
| Bhavyank | Good night guys!! |
| Bhavyank | has left the room |
| DeltaDroid | has left the room |
| Mark M. | turned off guest access |
