Re: [android-developers] Re: App Development for conducting classes
Why? Most information you need is somewhere on developer.android.com and related sites. Not every book is as useful as every other. Do you have a particular book in mind? I agree with Lew, most Android books are just the API reference printed on trees and nothing more, and that's at best. That being said, Mark's books are pretty helpful, even if I could learn the stuff by looking through the references, his explanations are pretty quick and help get people up to speed quickly in a way that isn't tacky, patronizing, or overly jokey to make up for the lack of actual content... this is in contrast to most of the programming books out there, kris -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] how to .setText of a String with different colours?
Hi I'm Oriol and I want to set a string like this one: H*i,* A*ll!* * * in the textView I've created on my layout. (One String in only one textView) But the matter it's that I don't know how to set a different colour for some specific characters inside my string. (Like in the example I show here) Does anyone knows how to do it? Thank you very much, Oriol -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Handler or (Local) BroadcastReceiver
Hi, I am working on a fairly complex bit of code. I would like your input to understand which (if any at all) of the above classes I should use. The short description is that I have an Activity that displays local HTML5 within a WebView. The WebView utilises a WebViewClient which intercepts URL requests from the HTML5 implementation (I realise that on Android the HTML5/javascript implementation can directly call native code but unfortunately the HTML5 needs to be x-platform (i.e. run on iOS) so I am forced to communicate through intercepting URL's that are being loaded). The application also has a separate Thread that I use to communicate with an external server across the network. 1: When the native Android code wants to do a javascript call in the WebView object, does this need to be done via the main application thread or could for instance the external server Thread do a WebView.loadURL(javascript:..) directly? 2: Is the HTML5/javascript implementation run by the main thread? In other words, is the WebViewClient.shouldOverrideUrlLoading() called by the main application thread? 3: I implemented PUSH notifications within the application and I am currently using a BroadCastReceiver in my Activity to receive broadcast messages from the cloud messaging IntentService I added. As the Activity already contains a Broadcastreceiver - should the external server Thread (in case the answer to 1 is yes) and the WebViewClient (in case the answer to 2 is no) also send a broadcast message to report to the Activity or should I implement an additional message Handler? - on a sidenote .. I just read that I cannot perform timeconsuming actions from the BroadcastReceiver.onReceive() method. (apparently not even open pop-up dialogs although that is exactly what I do and works fine on both the simulator and a range of real devices) ... what is the solution here? Hope I explained the situation clear enough :) Cheers, Lieuwe -- You received this message because you are subscribed to the Google Groups Android Developers group.

Actually, I take that partially back. PhoneGap is definitely capable of giving the illusion of injected JavaScript objects. Whether they are doing that on iOS actually via injected JavaScript objects or via some JavaScript wrapper that uses URLs under the covers, I cannot say, as I haven't looked. Regardless, in terms of your other questions, looking at how PhoneGap handles such issues with their Android implementation is a reasonable move, as that's probably the most heavily exercised hunk of WebView-embedding code out there. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 4.1 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

I'm guessing your problem lies in how you call AsyncTask.execute(…). Switching

s.execute(URL + param);
might fix it. I'm not too familiar with AsyncTask though…

Re: [android-developers] global_context
Yes, this is quite bad. Contexts can change, for example when an activity
is destroyed and recreated, a new context is given to it. Additionally, you
are storing the application context, which cannot be used in all
situations. For example, you'd get an exception if you tried to create an
AlertDialog using this context.

I'm guessing your problem lies in how you call AsyncTask.execute(…).
Switching this call to;
s.execute(URL + param);
might fix it. I'm not too familiar with AsyncTask though…

[android-developers] Are there any official Google sponsored training seminars/classes, etc?
I'm looking for information on officially sponsored training seminars/classes etc? I'm not really interested in online but will take some info on that if you have it. What I'm really interested in are seminars/courses that you pay for, have to go to the location, and take classes ranging from fundamentals to advanced. I've seen a couple of workshops posted around the interwebs and these might be just as productive as something Google sponsors but without any reviews or anything I don't know how comfortable I am giving just anyone $1K+ on an advertisement for training. Local colleges have options as well, but mainly I'm looking for more of a workshop style that isn't intending on teaching you from scratch. We've got guys who are already senior programmers in other languages that are not going to be interested in going to school for a semester! A week long course would be perfect to go out and bring home a few things. So does anyone know of anything like that? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?
I will mention that while not along the exact line you may be interested in, there is Google I/O, which always tends to have some interesting presentations.. Some courses might not be horrible, however, colleges might not be quite what you're looking for, but if you're near reputable universities they generally have pretty good classes.

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?
Before beginning, in the interests of full disclosure: I teach Android development in events much like what you describe. On Tue, Aug 28, 2012 at 4:00 PM, RKS sean.sambor...@live.com wrote: I'm looking for information on officially sponsored training seminars/classes etc? Are there week-long bootcamps and the like? Yes. Are they officially sponsored? Google doesn't officially sponsor much of anything, except stuff that they deliver themselves (e.g., workshops the day before Google I|O). I've seen a couple of workshops posted around the interwebs and these might be just as productive as something Google sponsors but without any reviews or anything I don't know how comfortable I am giving just anyone $1K+ on an advertisement for training. If you were in college, you'd determine whether to attend a course based on the instructor (knows her stuff? decent presenter?) and your available options given your need to take certain courses to graduate. Professional training is much the same, minus the cap and gown. What dictates the quality of the course tends to be the instructor (knows her stuff? decent presenter?) and the agenda (does it match what you need?). The agendas tend to be posted on the training firm's site. The instructors can usually be researched via your favorite search engine and such: - What's the instructor done, relative to Android? (wrote XYZ app? wrote XYZ book? worked on XYZ team?) - Are there signs that the instructor presents a lot, beyond just the training firm (e.g., conferences), and what comments regarding presentation style and the like can you glean from that? So does anyone know of anything like that? You do not say where you are located, and travel can be a major consideration. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 4.1 Available! -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: How do I read an XML Data in Android?
To create the XML file, I did this:
XmlSerializer serializer = Xml.newSerializer();
serializer.setOutput(fileos, UTF-8);
serializer.startDocument(null, Boolean.valueOf(true));
serializer.setFeature(http://xmlpull.org/v1/doc/features.html#indent-output;,
true);
serializer.startTag(null, produtos);
for (int currentProperty = 0; currentProperty
propertyResultCount; currentProperty++) {
SoapObject obj = (SoapObject)
objSoapObject.getProperty(currentProperty);
int attributeResultCount = obj.getPropertyCount();
serializer.startTag(null,
produto+currentProperty);
for (int index = 0; index attributeResultCount;
index++){
PropertyInfo pi = new PropertyInfo();
obj.getPropertyInfo(index, pi);
String tag = pi.name;
String value =
obj.getPropertyAsString(index).toString();
serializer.startTag(null, tag);
serializer.text(value);
serializer.endTag(null, tag);
}
serializer.endTag(null,produto+currentProperty);
}
serializer.endTag(null,produtos);
serializer.endDocument();
serializer.flush();
fileos.close();
I can use the same model to read the file and get every data information
that I need?
Another doubt, when I create the file, I need to use the explicit address,
for example:
File newxmlfile = new File(/data/data/dataplus.application/produto.xml);
Because I got some exceptions...
Why I can't access my Internal Storage or External Storage?
I set the permissions on the Manifest file...

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?
Ok man,there are google based training in mobile application development which take place in local universities here in kenya,i attended one this year from may to august and the training is totally free coz its google sponsored after the training there is a workshop where you develop apps for competition,this initiative is still on and during the training free start up manuals are provided which is easy to follow as a beginner until creation of simple apps to complex ones,if interested yoy can email me and i can send you the soft copy manual plus other useful materials and i can really assist you man,let me hear from you pliz,nyt On Aug 28, 2012 11:02 PM, RKS sean.sambor...@live.com wrote: -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Are there any official Google sponsored training seminars/classes, etc?
@Kris Thanks for the tips. We're in Houston so UH is reputable and offers traditional coursework in Android-specific application development. That certainly is an option, but I haven't had time to research the prerequisites and see if taking a course outside as a non-degree seeker if you can show competency in those required courses. Something to think about, thanks. @ Satya Unfortunately we're only a small 6 man shop with only 2 really working day-to-day on development that would take this training. @Mark Your last comment is the easiest, as we're located in Houston. That said, as long as the training is in the continental US, we're willing to travel. So I didn't really mention that since a) I didn't think about it and b) it doesn't matter since we'd go anywhere. Researching an instructor is good advice. In college I had to schedule my courses around each other and couldn't be so picky sometimes to hold off on a particular instructor. I can certainly see your point, though. I just ask about official Google because that's easiest at this point. For those who've been around the Android block a few times it might be easier to determine an individual's worth. For me, I'm just getting started. You may be able to recognize many key names or others who have been contributing to Android for quite some time and I would tell you I've never heard of them before. Then there's the guys who have developed apps, but are they learning from, etc. Thanks for the tips. I will look into everyone's comments and suggestions. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] ICS: White screen while changing visibility on Webview
Hi to all! I have a little app with a layout that it's something like this: FrameLayout FrameLayout ImageView/ ProgressBar/ /FrameLayout LinearLayout WebView/ /LinearLayout /FrameLayout I initially set the ImageView (kind of a place-holder) and the ProgressBar visibility to VISIBLE and the WebView's one to INVISIBLE. Then I call loadUrl on the WebView. When the page finishes loading (I use both onPageFinished and the detection of certain redirect on shouldOverrideUrlLoading on a custom WebViewClient) I finally set the visibility on the WebView to VISIBLE. Well, it works well on Android devices previous to Ice Cream Sandwich, but it seems like the WebView flashes to white before showing. I searched around for ideas and tried several combinations like letting the WebView as VISIBLE too and just hiding the place-holders, hiding them with GONE instead of INVISIBLE, replacing the image with a transparent one, and perhaps some others I already forgot. I'm testing with a Motorola Xoom recently (officially) updated to ICS; a couple weeks ago it had Honeycomb and the app worked just fine. Anyone had any similar problem or could think of any other way I can try? Thanks! Marina -- You received this message because you are subscribed to the Google Groups Android Developers group.

To load assets or resources you need to use the Application context...
Since what you are doing is using the Application context I think you
should be fine with this because this application context doesn't go away
until your application dies. *Note that if you want to do UI related stuff
you should most definitely NOT be using this context.*
However, you should note that a lot of classes provide access to a context,
and you really should be using that. For example, View has a getContext()
method, and you can use that to load assets or resources. But you
absolutely should not be passing this context around to things that will
outlast the view that you got it from.
http://developer.android.com/reference/android/view/View.html#getContext%28%29
Activities and Services both inherit from Context so you wouldn't need to
use your global_context in those cases either. In what situations are you
running into that you are using this global_context and don't have access
to it through another way?

[android-developers] Re: Handler or (Local) BroadcastReceiver
You could do both, if you abstract out the javascript-to-java calls in your HTML5's javascript - Create a javascript class in your HTML5 that implements a certain set of methods that define all the necessary javascript-to-java calls (abstraction). Let's call it 'CallToJava'. - On Android, register a javascript-interface; let's call this javascript object 'AndroidJS'. - In your HTML5's javascript, test if AndroidJS is defined or not. - If not, you're running on iOS. Implement/instantiate a CallToJava instance that uses URL interception for calling back into Java. - If it is defined, you're running on Android. Implement/instantiate a CallToJava instance that uses direct calls to the 'AndroidJS' javascript-interface. In the rest of your HTML5's javascript, use the instantiated CallToJava's methods to call back into your native iOS or Android code. As for in which threads javascript-to-java callbacks run: My experience is that callbacks into the javascript-interface is done on a WebViewCore thread, not the main UI thread. Use a Handler to post back to the main UI-thread if that is necessary. If in doubt, try it in the debugger and see which thread is being used. About the Broadcaster's onReceive: To handle longer running operations, look at Marks' *WakefullIntentService *(just google it) :-).

I would like your input to understand which (if any at all) of the above classes I should use. The short description is that I have an Activity that displays local HTML5 within a WebView. The WebView utilises a WebViewClient which intercepts URL requests from the HTML5 implementation (I realise that on Android the HTML5/javascript implementation can directly call native code but unfortunately the HTML5 needs to be x-platform (i.e. run on iOS) so I am forced to communicate through intercepting URL's that are being loaded). The application also has a separate Thread that I use to communicate with an external server across the network. 1: When the native Android code wants to do a javascript call in the WebView object, does this need to be done via the main application thread or could for instance the external server Thread do a WebView.loadURL(javascript:..) directly? 2: Is the HTML5/javascript implementation run by the main thread? In other words, is the WebViewClient.shouldOverrideUrlLoading() called by the main application thread? 3: I implemented PUSH notifications within the application and I am currently using a BroadCastReceiver in my Activity to receive broadcast messages from the cloud messaging IntentService I added. As the Activity already contains a Broadcastreceiver - should the external server Thread (in case the answer to 1 is yes) and the WebViewClient (in case the answer to 2 is no) also send a broadcast message to report to the Activity or should I implement an additional message Handler? - on a sidenote .. I just read that I cannot perform timeconsuming actions from the BroadcastReceiver.onReceive() method. (apparently not even open pop-up dialogs although that is exactly what I do and works fine on both the simulator and a range of real devices) ... what is the solution here?

Re: [android-developers] global_context
As long as *global_context *is an Application object, it is 'alive' as long as the (DalvikVM) process is alive (and vice-versa). As long as this context is only used to load assets/resources, this should be fine. Having such a global context (*application *context would be a better word) could be handy for deep calls, where you want to avoid passing a context object down the call stack as a parameter just to load a simple string-resource, for example.

Re: [android-developers] ViewPager and setClipChildren(false)
Mark, a huge thank you!! I never thought the problem would come from hardware acceleration (I'm a beginner after all ^_^). Indeed, my current rom force hardware acceleration for all applications. I tried to force software mode just on the ViewPager with setLayerType(View.LAYER_TYPE_SOFTWARE, null) (see here : http://developer.android.com/guide/topics/graphics/hardware-accel.html) but it doesn't work : content stay inside the viewpager. But by specifying it in the manifest as you say it works very well! And given the application, it does not pose any problems to do without hardware acceleration. Again, thank you very much Mark!

Since the issues of clipping and hardware acceleration are beyond my area of expertise, I can't explain why this is the case. Rather than disable hardware acceleration for the whole activity, you could experiment with disabling it just for the ViewPager itself.

Re: [android-developers] ICS: White screen while changing visibility on Webview
I see WebView flash white on 3.0 - 4.0 (inclusive) if GPU acceleration is on. This happens even if the WebView's Android background as well as body background are set to black. Disabling GPU acceleration in the manifest fixed the issue for me. This appears to be fixed in the official 4.1.1 (Galaxy Nexus), where GPU accel can be kept on, and the white flash does not happen. -- K 2012/8/29 Marina Cuello marina.ear...@gmail.com Hi to all! I have a little app with a layout that it's something like this: FrameLayout FrameLayout ImageView/ ProgressBar/ /FrameLayout LinearLayout WebView/ /LinearLayout /FrameLayout I initially set the ImageView (kind of a place-holder) and the ProgressBar visibility to VISIBLE and the WebView's one to INVISIBLE. Then I call loadUrl on the WebView. When the page finishes loading (I use both onPageFinished and the detection of certain redirect on shouldOverrideUrlLoading on a custom WebViewClient) I finally set the visibility on the WebView to VISIBLE. Well, it works well on Android devices previous to Ice Cream Sandwich, but it seems like the WebView flashes to white before showing. I searched around for ideas and tried several combinations like letting the WebView as VISIBLE too and just hiding the place-holders, hiding them with GONE instead of INVISIBLE, replacing the image with a transparent one, and perhaps some others I already forgot. I'm testing with a Motorola Xoom recently (officially) updated to ICS; a couple weeks ago it had Honeycomb and the app worked just fine. Anyone had any similar problem or could think of any other way I can try? Thanks! Marina -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: ViewPager and setClipChildren(false)
Thesalan -
Calling setLayerType() on just the View will work, but you have to do it on
the correct view. In this case, the issue that doesn't work with hardware
acceleration is the parent ViewGroup clipping its children, so the
PagerContainer in the example is the view that you need to call it on, not
the ViewPager itself. If you modify PagerContainer.java in the gist like
so:
private void init() {
setClipChildren(false);
setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
You should be able to enable hardware acceleration in your manifest and the
pager code will still work as expected. I will update the gist example
when I have a spare moment with some discussion, and I have starred the
issue Mark created (you should do the same).
Cheers,
Dave Smith

The result looks like this :

The ViewPager here is just on Item4, and with setClipChildren(false) we
can see the other item.
This works greats on emulator (tested on API 7 to 16) and some devices!
But I encounter some problems on more recent devices, like HTC One X
(Android 4.0.4) and a Nexus S (CM10 - Android 4.1.1) : the ViewPager
doesn't really extended! Just the current item is shown, and when you are
sliding, the next item is shown :

Anybody else already encounter this problem? I think is an optimization on
these devices, but how can I bypass this?

[android-developers] ICS Camera vs JB Camera

[android-developers] USB Host hardware requirements?
Hi All,
I have a USB based sensor that would draw about 300mA and would like to use
it with my Android phone. I have tried to play around with the API's and
write a small application that would just list out the devices that were
connected to the USB bus.
A small code snippet that I am trying to use to print out the connected
devices is:
*
EditText lsusbText = (EditText) findViewById(R.id.lsusbTextID);
lsusbText.setText();
Log.i(TAG, Querying USB devices);
UsbManager manager = (UsbManager) getSystemService(Context.USB_SERVICE);
HashMapString, UsbDevice deviceList = manager.getDeviceList();
IteratorUsbDevice deviceIterator = deviceList.values().iterator();
while(deviceIterator.hasNext()){
UsbDevice device = deviceIterator.next();
//your code
lsusbText.append(device.getDeviceName());
}
My manifest has:
uses-feature android:name=android.hardware.usb.host /
intent-filter
action android:name=android.hardware.usb.action.USB_DEVICE_ATTACHED /
/intent-filter
*
I noticed that the results are not showing any devices connected. After
researching a bit and poking around in the forums, it seems that only
specific hardware devices support USB Host mode. I have a Samsung Nexus S
phone, and am inclined to believe that this phone does not support the USB
host mode? I also tried plugging in a mouse via an OTG adapter, but the
USB mouse didn't receive power after it was plugged in. The Android API's
also suggest this:
Note: Support for USB host and accessory modes are ultimately dependant on
the device's hardware, regardless of platform level.
Is there a listing of the Android powered devices that support USB host
mode? Also, out of curiosity, why is there a hardware requirement for USB
host? Is it the specific type of USB connector that the phone has (Micro-A
vs Micro-B)? Is it something related to the USB Bus power? Any
information regarding the hardware requirements, which devices currently
support this, etc would be great. I also found that there is a libusb port
to Android, which would allow access at a lower level. However, this would
potentially still require the hardware to support the USB host mode.
Additionally, I have seen things about a kernel mod required. I'm
guessing the kernel stuff was for older image releases, and that Android
4.1 has this kernel mod built in.
I unfortunately found that the documentation for WiFi direct is similarly
ambiguous in that although WiFi direct is something that is enabled and
available for use in the API, the hardware may not support it. However, I
haven't found any documentation which tells developers which devices
support/don't support the functionality.
Thanks in advance,
Kiran

[sic] please help Eclipse is not the problem. What utilities did you go into? Are you referring to the menu entry Eclipse/Preferences/Java/Installed JREs? Java 5 is obsolete. Upgrade to Java 6 or 7. Follow Eclipse's instructions for making the new JRE (JDK, in your case) one of the Installed JREs. I use Eclipse for Android work and I've installed the Java SE 6 that is the MacOS X default - well, actually, Eclipse installed it for me when I installed Eclipse. What Android packages are you trying to get to interact with Eclipse, and what do you mean exactly by interact? Did you download the Android Development Kit (ADK) and associated tools as instructed on the Android web site? Did you download and install the Eclipse Android plugin as instructed on the Android web site? -- Lew Errol Raymond r3whitme...@gmail.com Aug 28 08:29PM -0400 I was referring to utilities folder in my application directory also after trying to install jdk7u6 it returned a javascript error I am using leopard so I guess there is no getting around that if I need a later version osx, due to the fact that this is the latest version for my system I suppose if eclipse had installed the java package for me then I would have no problems with getting the android sdk manager to run, but for me this is not the case I believe that I followed the instructions correctly, and could be wrong so I will try to get jdk 6 or better installed before crying for more help I want to get to the part of installing the android packages right after I install the adt plugin and restart eclipse, but I didn't get the dialog to run after restart (interact - for lack of a better word) thanks MapFragmenthttp://groups.google.com/group/android-developers/t/29f133be089b6d9e metal mikey coref...@gmail.com Aug 28 05:03PM -0700 I made a little library, mashing up the LocalActivityManager-based solutions for the MapFragment problem: https://github.com/coreform/android-tandemactivities Is certificate pinning possible to do with a WebView?http://groups.google.com/group/android-developers/t/1382d351f295e35d paladin quoti...@gmail.com Aug 28 04:50PM -0700 Not via an explicit https connection, but using a WebView, can I make it do certificate pinning?

Re: [android-developers] Get cellular signal frequency?
That's worth mentioning, generally the stats reported by telephony hardware are highly nominal at best and will change or fluctuate quite a bit depending on the protocol, etc...

[android-developers] Best way to do a refresh?
I am writing a single-activity Android app that accesses data from various places on the internet and displays it on the screen. This data can change over time. I need to give the user the option to do a manual refresh when he chooses, in order to get the latest values. I have it set up as an option on the options menu when the user clicks the Menu button on the handset. But I think my implementation is faulty. Right now I have it set up as an intent to launch the activity again, so that it will automatically retrieve the latest values. The problem is that does not terminate the previous activity. So when the user pushes the escape button, they are back on the previous execution of the activity, which is the same app with the old data. Is there some way to terminate the old activity and then launch it again? Or is there a better way to do a refresh? Thanks. -- You received this message because you are subscribed to the Google Groups Android Developers group.

(I also have an EE degree, and can attest to most hardware being kind of flakey..) Yeah, that's also often true. But the utter uselessness of trying to switch antennas every single time the cell tower in use tells the phone to switch frequencies make it a moot point (not to mention trying to design multiple antennas that have that tight of a frequency range... something we generally leave to the receiver's front end). :-) Later, --jim -- THE SCORE: ME: 2 CANCER: 0 73 DE N5IAL (/4)MiSTie #49997 Running Mac OS X Lion spooky1...@gmail.com ICBM/Hurricane: 30.44406N 86.59909W Do not look into waveguide with remaining eye.

There is, you would call finish() on the current Activity before starting the new one, but this is very silly. Or is there a better way to do a refresh? When the user hits the refresh option, instead of restarting the Activity, simply cal whatever method the Activity calls when it starts up to do the initial refresh. - TreKing http://sites.google.com/site/rezmobileapps/treking - Chicago transit tracking app for Android-powered devices -- You received this message because you are subscribed to the Google Groups Android Developers group.
