[android-developers] Re: Help needed with parsing some XML data !
hehe, my bad I said Netbeans but I actually use Eclipse :P Still used to J2ME with NetBeans thats why I mixed up... Anyways, I do get the error (exception) which I already posted in one of my first posts : At line 40, column 23: not well-formed (invalid token) They *MUST* be valid printing Unicode characters. No random control characters -- for example, ISO-8859-1 byte values 0-31 (decimal). This will ALWAYS fail -- it is NOT well- formed XML.

Seehttp://junit.orgas a starting point. (The Android SDK includes some limited version of JUnit I don't recognize. It's adequate for this purpose, but the full, modern version is better. For non-device testing, you're not restricted to the supplied one.) Basically, a test case is code that you can run to *automatically* test some specific aspect of a system. In this case, checking against a known set of XML (so it doesn't change), looking for the known desired result, and reporting failures (expected conditions not matching) and errors (unexpected exceptions thrown). This removes the variables from the equation. You're not depending on how things display, either in the UI nor in the log stream and windows. You're not dependent on a human to notice a problem. An best of all, you can automate it to always run when you build, so if you break later, you'll find out right away, while you know what you changed. And you can make changes freely, with the security of knowing that you won't have to go through some long test/debug cycle. I didn't answer your question about getting a stacktrace earlier, because you said NetBeans. I'm old enough to remember when NetBeans was the hot new thing -- but too old to remember how to do anything with it. Try using Eclipse and the ADK. It will show you the stack trace in the same way it shows any other stack trace, as if you were debugging locally. (I would expect NetBeans to, as well). Or you can catch the exception, and use exception.printStackTrace() to get it into the log (I'm surprised it's not already there). This isn't really an Android problem, and it's not necessary to debug it there. If you write your failing test cases, you can debug them on your desktop computer, get them working, and you should be set to go on the device. Another thing to realize is that not all character values you can come up with, are legal XML content. They *MUST* be valid printing Unicode characters. No random control characters -- for example, ISO-8859-1 byte values 0-31 (decimal). This will ALWAYS fail -- it is NOT well- formed XML. If that's the cause of your exceptions, your two choices would be to fix it on the server (probably by encoding this binary data) or to preprocess the fake-XML into real XML before you feed it to the XML parser. \ On Feb 3, 6:49 am, MobDev developm...@mobilaria.com wrote: well to begin with : thx for the expalanation :D I was wondering about your statement : Try logging to a file.

But it's something I'd never rely on if I know the encoding. Anyway, re: your problem below. It's probably working right, up to the point of the log statement. The log stream is probably taking those bytes, and then later they're being interpreted as UTF-8. or it's taking the characters from the string, and interpreting them as UTF-8 (via String.getBytes()) and passing them off to a log stream that doesn't know about

[android-developers] Re: sticky client IP address?
Hi, My answer wasn't incorrect... you are simply misunderstanding what end-to-end means in this context. This is getting a bit off topic, but it's interesting stuff. TCP/IP begins and ends at the edge of the cell network, on the network providers Internet gateway. Between the gateway and the phone itself there is no TCP/IP. This is the exact reason why you CANNOT build TCP/ IP connections from a server to a phone. You can ONLY build connections from a phone to a server. For further clarification see http://en.wikipedia.org/wiki/Packet_Data_Protocol#PDP_Context When the gateway receives the outgoing request from the phone, the gateway assigns its own IP address and a port number to the request and puts it on to the Internet as a standard TCP/IP data packet. This context may exist for some time on the gateway, or it may be flushed very quickly, there is no way to predict. It's not even possible for the application on the phone to know what IP address is being used on its behalf. The packet coming back to the phone is stripped of its TCP/IP envelope at the gateway and then put on the cell network using whatever packet technology the cell network uses. This is the very meaning of the word gateway... it is a gateway between two completely different networks that work in completely different ways, it is a protocol converter. - Mike NAVTEQ Network for Developers http://NN4D.com Disclaimer: I work for NAVTEQ and these are my personal opinions which do not necessarily reflect NAVTEQ’s views On 4 Feb, 07:13, Bob Kerns r...@acm.org wrote: This isn't correct, or is misleading. It's kind of like saying ethernet doesn't use TCP/IP or WiFi doesn't use TCP/IP or dialup modems don't use TCP/IP or DSL doesn't use TCP/IP or Cable doesn't use TCP/IP. If you drop below the level of TCP/IP, to how the data is physically moved, then yes, you are below TCP/IP, and in that sense, cell networks don't use TCP/IP. However, they CARRY TCP/IPtraffic. And that's what thoseIPaddresses are --IPaddresses. You can establish TCP connections. TCP/IPis actually two protocols.IPis the lower-level of the two, handling addressing and routing. It is completely agnostic as to how the packets are transported. You could use carrier pigeons. Really! http://www.rfc-editor.org/rfc/rfc1149.txt I don't know if anybody's done it -- but it wouldn't surprise me. TCP is on top ofIP, and gives you reliable transmission and end-to- end connection semantics. Now, perhaps you meant to contrast the situation with VOIP, where voice is carried overIP. Indeed, voice data is not (normally) carried over cell networks as TCP/IP, though it's possible. (Not necessarily acceptable, but possible). But every phone with a data plan is using the cell networks to carry TCP/IP. Your gatewayaddresswill be theaddressof the gateway server, but yourIPaddresswill be yourIPaddressthat your server uses to send traffic to you. I don't know the current state of the art for how stable your phone'sIPaddresswill be. I can tell you that my phone switches cell sites surprisingly often, but I've not watched theIPaddresses simultaneously. But you don't switchIPaddresses when you move from Access Point to Access Point on the same WiFi network. In theory, you could retain the sameIPaddressfor the life of your phone, with a sufficiently clever and powerful cell network. In practice, however, that's unreasonable. But perhaps someone can tell me just when it changes. And why, after rebooting, I have TWO? One for each tower? We're at the limits of my networking knowledge when we come to the specifics of how it's layered on top of the cellular network. BTW, Vertifi, this Class B/Class C terminology is long obsolete; addresses have not been allocated by that scheme for many years. It consumed too much IPv4addressspace. Instead, the number of prefix bits is specified, like 192.168.0.0/24 -- where 24 is not necessarily a multiple of 8. I don't know if your server farm people are expecting Class C to refer to distinct networks, or simply using the term as a holdover, but treating it as the arbitrary distinction that it is. But certainly we should not import any significance to thoseIPaddresses being allocated from some larger block than /24. They could all be from the same subnet, so far as the cellular network is concerned. This would be some network in some bunker somewhere, with a bunch of NAT servers, with multiple hot connections to various pieces of the backbone. TheIPaddressassigned to the phone will be anaddressspecific to the link between you and the next piece of equipment that actually treats your data as TCP/IPtraffic. My iPhone reports it as 10.135.130.117; I've never seen it other than a 10.0.0.0/8 non- routable privateaddress. This is translated via NAT further upstream, so servers on the other end see a routableIPaddress; at the moment, mine is 98.210.255.162. In theory, this can be different for

Hello all,
This one is quite simple, or should be, but I couldn't figure out how
to.
So ...
I have a Gallery, something like :
Gallery android:id=@+id/Gallery01
android:layout_width=fill_parent
android:layout_height=wrap_content android:spacing=0sp/Gallery
Inside, custom views : first item has a width of 200px, all other
items have a width of 150px.
Now, in landscape mode, with a screen of -let's say- 800px :
- by default the first item is selected;
- by default the selected item is positioned in a slot so that its
center is the gallery's center;
- so, when first loading the gallery, the layout is :
* 300 px that are empty
* 200 px with first item
* 2 * 150px with second and third items.
* = Total of 800px
Now, the behavior I try to reach is to have the first item taking the
empty space at its left, to have the following layout :
* 200 px with first item
* 4 * 150px with items 2, 3, 4 5
* = Total of 800px
I tried :
- scrollx on gallery : it moves the whole view to the left, NOK
- padding : NOK
- margin : NOK
...
Any idea ?

[android-developers] Resizing video on the Nexus One turns surface white
In order to offer embedded or fullscreen video, I attach the MediaPlayer to a SurfaceView which is inside a LinearLayout and then change the parent's padding values to reposition and resize the video. This works on all devices except the Nexus One. On the Nexus One, as soon as the surface size changes it goes white so the audio continues but the video is lost. Each time the surface is resized, it's possible to see a single frame before it goes white again. Does anyone know if this is a bug or is there an alternative way to go to full screen? I do already call SurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS), without which the surface remains black throughout. As a workaround, I'm trying to launch a separate activity with a separate layout and pass the player through, but at the moment that's not working either. Should that be possible or can a MediaPlayer not be re-assigned to a new SurfaceView once it's started?

Like the others said.. it sounds like a starting element is not being found
before either some text or an end tag. Usually you'll see that error with
something like:
node1
/node2
node3
/node3
/node1
Or
node1
/node1
some text
node2
/node2
It ALSO depends on how you are moving thru the xml parser.. if you are using
parser.next() you are moving one parsing element at a time, which means
you'll find every possible element including text, tags,white space, etc. If
you use parser.nextTag() you may skip over that 2nd example text issue and
find node2 start tag.

might not be anything you can do.

[android-developers] Re: sticky client IP address?
Indeed, interesting stuff. Thanks for the reference to PDP; it explained a few of the lower-level things that have been puzzling me. However, it's still misleading, because you are focusing on the transport layer, and NOT on the TCP/IP layer. It is not correct that TCP/IP begins and ends at the edge of the cell network, on the network provider's Internet gateway -- UNLESS you would choose to describe your typical home network with NAT router that way. The usual way to describe this situation is, You have TCP/IP connectivity to the internet, but sit behind a firewall. Indeed, you can't build IP connections to your phone via the cellular path. (Except maybe you can reply with an FTP data connection -- dunno, haven't tried it. That would be up to the gateway to allow or not -- and the only way it would allow it would be based on having an outgoing FTP control connection, and doing the reverse translation when the connection comes back. I can think of several good reasons NOT to support this.) However, the connection by which I will post this, from my laptop, is generally considered to be a TCP/IP connection. From *MY* side, I really can't tell that there's any NAT going on. My browser will do a DNS lookup (which will be handled by my router), giving me a routable IP address for Google's groups.google.com server. My laptop happens to be hardwired at the moment, so it'll go directly to Ethernet, after first wrapping the TCP/IP packets in ethernet headers. At my network's edge, the ethernet headers will be stripped, and the IP headers will be stripped and new ones created. My private IP address will be replaced with one that Comcast has assigned me. Comcast could do the same trick, of giving me a private IP address and using NAT at their edge, but they don't. (The economics are different -- the amount of bandwidth involved is hugely more). My router will then put on new ethernet headers, to transmit to my cable modem, which will strip them off, update the hop count in the IP headers, and wrap them in DOCSIS headers for transmission on the cable modem. The cable head will strip the DOCSIS headers, and forward the TCP/IP payload to the next hop, after incrementing the hop count. At any point along the way, these packets may be split up into smaller packets. Google will see, not the IP address of my laptop, but the IP address assigned by Comcast. This address is shared by all the devices on my home network, including my phones. Well, except for my digital Comcast phone, and my cable box, each of which has its own IP address! PDP is no different from any of this transport layer stuff. It is basically a frame relay system, according to your reference -- and I was running TCP/IP over frame relay in 1995. So why does all this matter? It's best to look at it functionally: Here's what's in it for us, at the level of TCP/IP: * We can open TCP/IP connections normally. * Our IP address, when communicating over the cellular network will not be the one that the server sees. The source port may be different, too. * We cannot get incoming TCP/IP requests from the cellular network. * This is no different from being behind a NAT firewall, except no possibility of the admin opening up an incoming port forwarding for you. * Traceroute will show you the hops that the IP traffic takes, but not show you any internal structure those hops may have. You only see the IP routers along the way. * You can't even tell that any of this is going on -- except by the incoming silence, or sites that explicitly report back to you what IP address they see. To illustrate this, here's my phone's current state (I just turned off the wifi): rmnet0Link encap:Ethernet HWaddr EE:B1:E9:38:05:3D inet addr:25.128.179.204 Bcast:25.128.179.207 Mask: 255.255.255.252 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:21853 errors:0 dropped:0 overruns:0 frame:0 TX packets:21170 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7958701 (7.5 MiB) TX bytes:2785940 (2.6 MiB) # /system/xbin/bb/route /system/xbin/bb/route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.165.17.242 * 255.255.255.255 UH0 0 0 rmnet0 10.177.0.34 * 255.255.255.255 UH0 0 0 rmnet0 25.128.179.204 * 255.255.255.252 U 0 0 0 rmnet0 default 25.128.179.205 0.0.0.0 UG0 0 0 rmnet0 The 25.128.179.204/30 subnet is a point-to-point link, consuming 4 IP addresses, but those IP addresses only mean anything to the two partners. All traffic goes to that 25.128.168.205 on the other end of the radio link. It's not processed as TCP/IP until it reaches there -- until then, it's just travelling a virtual circuit, taking all net traffic from my phone to that destination. Eventually, my IP address in the source address header fields is

Well, to be honest your first idea was also mine :P So I already looked via Google but to be honest I haven't found that many clear discussions/ explanations... I also tried idea 2 and this is what I got : Congratulations The document located at http://x was successfully checked as well-formed XML. This means that we were not able to determine the exact document type, but that the document passed the XML well- formedness syntax check. If you wish to wish to perform formal validation of the document, you can use the Document Type: option of the validator. But also this has been found, even though I do not know how important this is : The DOCTYPE Declaration was not recognized or is missing. This probably means that the Formal Public Identifier contains a spelling error, or that the Declaration is not using correct syntax, or that your XML document is not using a DOCTYPE Declaration. Validation of the document has been skipped, and a simple check of the well-formedness of the XML syntax has been performed instead. Als, just to point out, at this point i CAN read out the XML stream by using the Xml.parse(is, Xml.Encoding.ISO_8859_1, new ExampleHandler(myAdapter)); method...

[android-developers] Re: sticky client IP address?
Your description of NAT and firewalls is entirely correct. Unfortunately, NAT is not a good description for what is actually happening on the cell network. In the case of your home PC behind a NAT and Google (or the Internet) on the other side... both networks on each side of the NAT are in fact using TCP/IP to transport data packets around. However, in the case of the cell network, the transport protocol is NOT TCP/IP. The use of TCP/IP is only relevant on the Internet side of the gateway. An IP address is entirely meaningless within the cell network. The part which is similar to the operation of NAT is that the gateway maintains a table of which port numbers are associated with which cell phones (the PDP Context). Outgoing packets create a context which includes the gateway IP address and a port number on that gateway. The gateway creates a table of port numbers and their associated devices, responses coming back to that specific port are then routed to the device using whatever transport protocol the cell network uses (GSM, EDGE, GPRS, CDMA, etc). It is quite likely (depending on how busy the gateway is) that once the response has been received, the PDP Context is freed and your next PDP Context will almost certainly have a diffierent port number, if not a different IP address. And (on the same topic) this explains why you might sometimes see two different IP adresses as being associated with your cell phone at the same time. Each and every connection to the Internet follows its own path and those paths can easily be assigned a different gateway... which cell tower you are connected to is entirely irrelevant in this context. - Mike NAVTEQ Network for Developers http://NN4D.com Disclaimer: I work for NAVTEQ and these are my personal opinions which do not necessarily reflect NAVTEQ’s views -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: DNS Query
Ah, this provides a lot more context -- but not all of it! Normally, this sort of thing is handled through DHCP or similar. I don't know if you have access to the server providing the information -- are you the carrier? To change the DNS resolution policies in any way, will require root access, and have global impact. Do you own these devices? Or are you developing an app for public consumption? The one (nearly) sure-fire way to do this, is to query the DNS server yourself, in the application. The (nearly) is because firewalls can intervene. I would urge you to avoid any sort of temporary change to the global DNS resolution. It's one thing if you have control over the device and pre-configure it for the users. But temporary changes to DNS configuration has a way of going bad when events happen in other than the expected order. And if you get two applications trying to impose THEIR will on an entire platform, it's a formula for chaos. I don't know how DNS resolution is configured on Android, but this may be useful: # getprop | grep dns [net.change]: [net.dnschange] [net.dnschange]: [878] [dhcp.eth0.dns1]: [] [dhcp.eth0.dns2]: [] [dhcp.eth0.dns3]: [] [dhcp.eth0.dns4]: [] [net.dns1]: [10.177.0.34] [net.rmnet0.dns1]: [10.177.0.34] [net.rmnet0.dns2]: [10.165.17.242] [net.dns1.161]: [10.177.0.34] [net.dns2.161]: [10.165.17.242] [net.dns2]: [10.165.17.242] [net.dns1.79]: [10.177.0.34] [net.dns2.79]: [10.165.17.242] [net.dns1.31939]: [] [net.dns2.31939]: [] # If you're connected via wifi, the dhcp.eth0.dns* entries are filled in instead; the above is with Wifi disabled. Still -- and I don't know the 3GPP protocols here, but if they're not deviating too much from how things were designed, any old DNS server should be able to supply you with the information. The DNS server you contact will, based on the domain requested, contact the appropriate DNS server and obtain the information, cache it, and relay it to the requester. Perhaps this is not suitable for this for some reason, but if so, realize the reason it's hard is because 3GPP is doing it wrong -- that is, using tools in ways they weren't intended. Maybe it's all worthwhile; I don't know, I'm just trying to give you helpful context and info, not technical judgments. Fun historical fact: In 39 days (March 15), it will be the 25th anniversary of the very first DNS registration, Symbolics.com. (The domain name was recently purchased).

[android-developers] Re: Android 2.0.1 SocketTimeoutException received with FTP Data channel
Ah, given that both sides are loopback, TCP/IP doesn't really even enter into it in a meaningful way. I think the problem pretty much has to be with your client. I began suspecting that once you mentioned that closed connections stayed open until you killed the process. A RST on one should trigger a close on the other side. I've had good luck with openSSH, and though I've not used it heavily, I've heard good things from others, so I think it's a solid choice. But google around, there are others. Another possibility is to use OpenVPN. This will let your clients talk directly to the target server or servers, rather than to a local forwarded port. This is a lot more flexible, if that's a good thing. If you want to lock down and limit access, you're better off with port following. On Feb 3, 10:55 pm, mericksonj mericks...@gmail.com wrote: The lack of an application-level timeout does explain why software will generally hang. The error message that I've seen the most is as follows: java.net.SocketTimeoutException: The operation timed out Now, in my tests with a PC, the sockets are generated and torn down dynamically with the client always connecting with its random port to the same passive port on the server. The android device will not tear the connection down however after the exception. The session will stay up indefinitely as established on both ends until I kill the port forwarding process. There does also appear to be situations where I can get a directory list received from the server to show up on the client device (subsequent cwd commands work, but list will fail), but it seems to be intermittent and very erratic. Which leads me to take more notice of the buffer messages rather than a specific point in the code that breaks down. As for NAT or Firewall issues, all client communications are looped.. meaning that with the TCP tunneling in place, all FTP packets are sent to 127.0.0.1 where it is picked up by SSH for crypto and encaps into another IP packet. Once at the SSH server, the outer packet is stripped, contents are decrypted and sent to the FTP server. The FTP server (same box as the SSH server) thinks it came from 127.0.0.1 and uses that same IP for its replies. I guess that's just the long way of saying that each device thinks it's talking to itself, so there's no NAT or firewall confusion. At least not until I move the FTP service off my SSH server, but even then IP masquerading in the proftpd_conf will fix the NAT issue. I really think a TCP dump would help the issue.. at least I could see how big the FTP packets are, if they're being fragmented, and when/ where they're being sent. I just found the tcpdump on the emulator, how can I filter out the non-interesting packets? I would like to try similar port forwarding tests using adb or other tools, is there a recommended tutorial on how to use the port forwarding there? will it be able to simulate what I'm doing with SSH? Also maybe trying a different SSH client would help, is there anyone besides connectbot that accepts RSA keys and allows TCP port forwarding? -- Regarding the security discussion, I think in my setup I'm pretty safe since all FTP packets are looped within client/server platforms as described above, but you do make a case for FTPS w/out encryption that could maybe alteast mask the username and password within the system or in case I ever do move the FTP server off the SSH box, then again, it is at least on a trusted network once the SSH server decrypts it.

[android-developers] Re: Text To Speech Android 1.6 with minsdk 3
Hello Tone, You definitely have to target the 1.6 (or greater) platform for this to compile. I remember having trouble getting the debugger to attach to the 1.5 emulator. I don't remember if I was able to do that or if I relied on Toast/log messages to zero in on my 1.5 specific issues. I'm not near the proper computer now to test it out. I vaguely recall having to make sure the 1.5 emulator was the only one running and I had to start it explicitly before running the application - not sure why that mattered, but... All of this may depend on what version of the SDK you have installed (1.6, 2.0, ...). Currently I have installed v2.0.

b ) {

There's more to it than onStop(). Check out onPause(), or better yet,
revisit the documentation on the Activity model.
So you get sense of the dynamic, override all activity methods, place
logs in them and play around so you get a feel which method gets
called when.

[android-developers] Re: Emma Code Coverage
A few more notes to make it clear. 1. The default built.xml can be copied to the tests folder and change the name of the project in build.xml to your test project's name. 2. You also need the build.properties application.package=your_test_package_name ( This has to be different than your tested project for obvious reasons) tested.project.dir=.. tested.project.absolute.dir=.. The remaining two properties are the location of your actual project you are testing All this is evident if you read the build.xml file and the template rules. (and I stand corrected on my previous post, the documentation is in the build.xml file and not in the template files ).

[android-developers] Draw clock like minute hand
Hi all.
Just a quick question, how would i go about implementing a clock like
hand that rotates around a centre point to different positions
depending on a value.
e.g. I send it a value of 3, and it points to the 3'o'clock position
of a circle.
protected void onDraw(Canvas canvas)
{
Paint line = new Paint();
line.setStrokeWidth(3);
line.setColor(Color.BLUE);
line.setStyle(Paint.Style.STROKE);
canvas.drawLine(55, 155, 125, 15, line);
}
I have the following fully working so it draws the line, but i dont
understand how i could get one end of the line to always rotate around
the centre fixed position.
Do you have any ideas?
Thanks.

[android-developers] ListView scrolling behavior and performance
Hi,
I have a listview showing contacts.
When I'm scrolling the list the scroll works pretty smooth however
when/if I'm trying to continue the scroll in the middle of the last
scrolling the scroll just stops and sometimes the item I clicked on is
selected (I have registered an OnClickListener to the item view).
I would like to get smooth scrolling just as in the device native
contact list.
My implementation builds each contact a view containing:
1. Big picture for the contact image.
2. Small picture for the type of the contact.
3. TextView with the Contact name
4. TextView with some extra text about that contact.
My current layout for every item looks like:
LinearLayout
ImageView /
LinearLayout/
LinearLayout/
ImageView /
TextView/
/LinearLayout
TextView/
/LinearLayout
/LinearLayout
I've tried changing the LinearLayouts to relative ones but saw no
improvement in performance.
I've created my own Selector in code (to eliminate the time it takes
to load the resource) so that odd rows will have different background
color. The code looks like:
StateListDrawable draw = new StateListDrawable();
draw.addState(new int[] {android.R.attr.state_selected},
mSelectedRowDrawable);
draw.addState(new int[] {-99},mOddRowBG);
draw.addState(new int[] {},mRowBG);
view.setBackgroundDrawable(draw);
I'll be glad to give more details if needed.
Thanks for the help.

[android-developers] About precise scan when doing garbage collection
Hi all I found that there are conservative scan and type precise scan when garbage collector scan the thread stack. Then I turn on the precise scan in the dalvim vm by adding some code in frameworks/base/core/jni/AndroidRuntime.cpp opt.optionString = -Xgenregmap; mOptions.add(opt); /* turn on precise GC while we're at it */ opt.optionString = -Xgc:precise; mOptions.add(opt); It surely assigns true to gDvm.preciseGc and generateRegisterMaps when the dalvik startup. However, in the function gcScanInterpStackReferences in dalvik/vm/ Thread.c, the variable const RegisterMap* pMap always gets null when the program executes: pMap = dvmGetExpandedRegisterMap(nonConstMethod);. Therefore, it always falls back to conservative scan. Did someone has made the dalvik scan the stack frame precisely? If so, teach me how to do it, please. It's very urgent. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] How do you deal with spammers?
Hi, Our app, aForum, is a very popular forum app on the market. It had very good user rating. Last week, our forum was spammed by some people out of nowhere all of a sudden. The spamming included constant meaningless posts and vulgar words for a while. We got short peaceful time after banning some people. Early this week, they staged a second round of attack. After some investigation, we found out these people were from a competing forum. We have clear evidence that this is a well-coordinated attack. From their forum, they even talked about how to hack our system to initiate further spamming. They left very low rating on our review plus flagging our app as inappropriate. This resulted in the decrease of our rating recently. Their forum does not seem to be moderated. I don't think their developers are involved in these attacks. But I think they are at least partially responsible for not doing diligent work because their app clearly violated the market content policy: http://www.android.com/us/developer-content-policy.html We reported this issue to the Android team and has not receive and response yet. I would like to know your opinions about this if you have similar situation. Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Installing a Game Media to SD Card
I have created a rather large game, 18 megs, and am sick of getting 1 star because of the size. Now normally I would just figure out how to do this on my own but since this is something I'm only doing because Google dropped the ball and may soon rectify, I would really appreciate it if some one would provide me with code to do the following. 1. Make an HTTP connection to a server and dowload a .zip file to the SD card. 2. Then unzip the file to a directory on the SD card. 3. Finally delete the .zip file. Has anyone done this before? What are the gotchas? I'm sure doing this comes at a cost, such as having to insure the graphics have been downloaded, failed downloads, and if you have a future update you have to manage updating the graphics yourself, am I missing anything?

[android-developers] Re: Pop-up without using Toast.
You could always just ask the developer. His email is in the City Caller ID application. But, since I am here... The best way to do anything in Android is to look at the source of Android. I looked at how a toast was done in the source and implemented my own version of it. You can message me directly if you need more information. I can't imagine Google would just want anybody doing this. That is why I won't post my Custom Toast code just yet. It could be really obnoxious if used incorrectly. Now if I could just figure out how to add the city and state to the Call Log. I have combed the source and it looks like I would need a custom Dialer Application. :( Take care, Chris On Jan 11, 12:45 pm, Klaus Kartou kar...@gmail.com wrote: Heh yeah, that is true :) But how do you display something over the in-call screen?

Hi all,
I've seen other posts on emulators, but none seem to match my issue.
Basically on a clean boot of my Ubuntu 9.04 64-bit system, I fire up
Eclipse, load my project, and run it in debug (or not) mode. Either way, the
emulator fires up, takes about 30 to 45 seconds to initialize, and my app
shows up. When I make some changes and rebuild my app, sometimes it reloads
properly. However, if I shut down the emulator at all, then relaunch it
fresh, I am constantly getting the following error in the console output:
emulator: ERROR: unexpected qemud char. channel close
Now, I run in DDMS perspective as well, and I see a bunch of threads start
up. I also see my app being deployed. Then slowly, all the threads including
the normal ones like Alarm clock, etc disappear. Then that error line shows
up. At this point, my app somehow shows up in the emulator (it's a google
maps app), and I have NOT had to press the menu key to get past the normal
lock screen. Not sure why when this thing crashes like this, I've not had to
use the lock screen menu press to see my app like I usually do.
I've not found any useful info on the specific error either.
Thank you for any help.

[android-developers] ObjectInputStream creation works in straight java, but fails on alternating calls inside Android
Below is some test code that works fine when run from the command line
(it prints out a phone number five times).
However, when I run this same code from within my android app, it
fails on every other call to “getit()”. Specifically, it fails on
this line:
inStream = new ObjectInputStream ( url.openStream() );
with a java.io.StreamCorruptedException. I have checked for version
differences in the java sdk, but that checked out okay.
How can I further track down the source of this error, which is
apparently specific to the android environment?

i have the exact same problem ...
i have an Activity that contains a Listview which is used in a Dialog
My ListView contains only TextViews. It's initialized in my own

it's working nicely except the main goal for me, select one of those

[android-developers] Jumping effect of Status Bar
Hi everybody
I have a problem with my app. I use the full screen option like so:
public void setFullscreen() {
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
But, later during the game, when I show the AlertDialog for Help /
Info, the status bar comes back for a fraction of a second and
disappears again creating a flashing or jumping effect. Also, the
Dialog itself is not centered as it should, almost as if it thought
there was a status bar.
Here is how I display the dialog:
protected Dialog onCreateDialog(int id) {
TextView tv;
switch (id) {
case MENU_HELP:
tv = new TextView(this);
tv.setText(R.strings.help_msg);
return new AlertDialog.Builder(BlackJackView.this)
.setIcon(android.R.drawable.ic_menu_help)
.setTitle(How-To)
.setView(tv)
.setPositiveButton(OK, new
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int
whichButton) {
/* User clicked OK so do some stuff */
}
})
.create();
}
………
}
return null;
}
Does anyone know what may be causing this appearing / disappearing?
How do I make it stop this jumping behavior?
Thanks for all your help.

[android-developers] Re: btsocket connected but read zero bytes
Good day.
I was able to create a stable connection to the BT device.
To do this, I changed your code:
BluetoothSocket btsocket =
btdev.createRfcommSocketToServiceRecord(uuid);
btsocket.connect();
Upon:
int RFCOMM_CHANEL = 1; //SPP chanel
Method m = btdev.getClass().getMethod(createRfcommSocket, new
Class[] { int.class });
BluetoothSocket connection = (BluetoothSocket) m.invoke(btdev,
RFCOMM_CHANEL);
connection.connect();
And now the connection has been stable and not broken and you can read
and receive data by input and output streams.

If android bt advertise it support role switch and it should fullfil the

support role switch so the remote device would not request role switch?
is that how it suppose to work? comments?

By disable role switch, I have successfully established connection, read

The behavior seems not right, and I think there may be a problem on my
Android phones. The following is what I observed from the protocol
analyzer:
1. Android makes a connection to remote device. It is succesful.
2. Remote device requests Role Switch.
= Android must response yes (I believe, otherwise, connection
would just stay and no further steps shall take place)
3. Android immediately disconnects the above connection.
4. The remote device attempts to establish a connection to my Android
phone, it fails. I can see the remote device trying to negotiate connection
rate but eventually giving up.
The above I believe 3 and 4 are the steps when role switch taken place. I
could be wrong but by disable role switch on remote device, the connection
is fairly robust.
May I request role switch feature for next release?
Best regards,
Sean

[android-developers] How to get Context Menu and panning work together in an app.
Hi,
I am trying to write an app which has an ImageView and the app allows
to perform panning on the image. I also want to register context menu
with this ImageView so that on long press Context menu comes up. I
tried playing around with the onTouch method, but could not get it
working.
On long press, i do see context menu. But, while panning also the
context menu comes up. I want that context menu is displayed only when
long press is performed and not while panning. If I return true from
the down event, the context menu fails to come up.
Please find the snippet of the code below for the reference.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView image = (ImageView) findViewById(R.id.image_id);
image.setOnTouchListener(this);
registerForContextMenu(image);
}
public boolean onTouch(View view, MotionEvent event)
{
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
mXPos = event.getRawX();
mYPos = event.getRawY();
return false;
case MotionEvent.ACTION_MOVE:
float newXPos = event.getRawX();
float newYPos = event.getRawY();
view.scrollBy((int)(mXPos - newXPos), (int)(mYPos -
newYPos));
mXPos = newXPos;
mYPos = newYPos;
return true;
case MotionEvent.ACTION_UP:
return false;
}
return false;
}
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
menu.add(Menu.NONE, 0, Menu.NONE, Item1);
menu.add(Menu.NONE, 1, Menu.NONE, Item2);
}

[android-developers] Preventing WakeLock Under-Locked exception
I'm trying to implement a times WakeLock in my Application, so this is
not a Service.
I want the wakelock to simply prevent screen dimming for 3 min.
Looking through the docs, this seems simple enough, but I seem to
randomly encounter a Under-Locked exception that I cannot pinpoint.
Here is my WakeLock-related code:
in onCreate:
...
PowerManager pm = (PowerManager)
getSystemService(Context.POWER_SERVICE);
mWakeLock =
pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, TAG);
// Adjust time to include user's setting
int timeout = WAKELOCK_TIME -
Settings.System.getInt(getContentResolver(), SCREEN_OFF_TIMEOUT, 0);
if (timeout 0) {
mWakeLock.acquire(timeout);
}
...
in onDestroy:
if (mWakeLock != null mWakeLock.isHeld() == true) {
try {
mWakeLock.release();
} catch (Exception e) {
// TODO Auto-generated catch block
//e.printStackTrace();
}
}
super.onDestroy();
As you can see, I wrap the release and try to only execute it when
necessary as a clean up only. I'm assuming that since I'm aquiring
with a timeout, the PowerManager will handle the release in most cases
when the timeout expires.
I don't have a copy of the logcat at the moment, but what seems to
happen is I get the Under-Locked exception randomly, and at random
times (it's not always when WAKELOCK_TIME elapses). The strange thing
is that the exception does not point to my code - all the entries
point to internal Android code.
It's hard to find examples of other people using aquire with timeouts.
Any ideas what I could be doing wrong here?

[android-developers] Textview with graphic (dynamically changing) inside.
Hello, I've a TextView that in the onCreate is build with an image to the left from the static drawables, and with a text in the right. I want to dynamically change the text and the image, (and maintain the same image size), I have the image stored in a Bitmap named bm, (yes I know I could change to a ImageButton and a textview but it has better layout and I want to know if it's possible what I try to do, the way I try) I've tried different thing like: Option 1: TextView tv=(TextView)this.findViewById(R.id.TextView01); BitmapDrawable bmd=new BitmapDrawable(bm); tv.setCompoundDrawables(bmd.getCurrent(), null, null, null); With this option the text remains inteact but NO image is draw... Option 2: the same but the end line is tv.setBackgroundDrawable(bmd.getCurrent()); The Textview resizes to the image size and the image is draw and the text is hidden by the image, not the desired behaviour... :-P Option 3: trying with canvas like: Canvas can = new Canvas(bm); Drawable d=tv.getBackground(); d.draw(can); I got an exception so this is far from the solution... Please any ideas of how can I achieve this? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] btsocket stable connection
Good day.
I was able to create a stable connection to the BT device.
To do this, I changed your code:
BluetoothSocket btsocket =
btdev.createRfcommSocketToServiceRecord(uuid);
btsocket.connect();
Upon:
int RFCOMM_CHANEL = 1; //SPP chanel
Method m = btdev.getClass().getMethod(createRfcommSocket, new
Class[] { int.class });
BluetoothSocket connection = (BluetoothSocket) m.invoke(btdev,
RFCOMM_CHANEL);
connection.connect();
And now the connection has been stable and not broken and you can read
and receive data by input and output streams.

Re: [android-developers] Re: options menu items
No, you cannot adjust the theme or layout of the default options menu (see http://code.google.com/p/android/issues/detail?id=4441). However, you can intercept the Menu button press and draw your own menu... On Thu, Feb 4, 2010 at 4:25 PM, Robert Nekic robertne...@gmail.com wrote: I was about to start looking into this, too.

Anyone look into or experienced the same problem using the role switch
feature? I think this may be a bug on the android sdk:
If android bt advertise it support role switch and it should fullfil the
request from remote device. Or, it should simply advertise that it doesn't
support role switch so the remote device would not request role switch?
is that how it suppose to work? comments?

We hooked up a BT protocol analyzer to monitor why connection getting
dropped right after connection. We are certain it is due to Role Switch.
By disable role switch, I have successfully established connection, read
and write.
The behavior seems not right, and I think there may be a problem on my
Android phones. The following is what I observed from the protocol
analyzer:
1. Android makes a connection to remote device. It is succesful.
2. Remote device requests Role Switch.
= Android must response yes (I believe, otherwise, connection
would just stay and no further steps shall take place)
3. Android immediately disconnects the above connection.
4. The remote device attempts to establish a connection to my Android
phone, it fails. I can see the remote device trying to negotiate connection
rate but eventually giving up.
The above I believe 3 and 4 are the steps when role switch taken place. I
could be wrong but by disable role switch on remote device, the connection
is fairly robust.
May I request role switch feature for next release?
Best regards,
Sean
