[android-developers] Re: best practice in extending classes
That should take care of itself. Initially only the Android system has a reference to that object of an internal class type (e.g. and Activity object. That reference is effectively a bridge. (Call it 'refB'). The object of an Android internal type can in turn have references to other objects but as soon as Android cuts that bridge all those other objects become unreachable and fair game for garbage collection. Where you get in trouble is if you give 'refB' to another object so that it is no longer a bridge. So, for instance don't give a reference of your activity to a service. Listeners are not a problem since the when you register the listener it is the widget that has a reference to the listener (not the listener having a reference to the widget) On Friday, June 8, 2012 5:18:57 AM UTC-4, marcin kolonko wrote: as of now, i set all class members to null, but do nothing inside classes i extended, like listeners or adapters or anonymous classes. would that be enough? -- You received this message because you are subscribed to the Google Groups Android Developers group.

Re: [android-developers] Re: Data interchange with a PHP server
Hi, For JS it is clear that JSON will be faster, but what is the better choose in Java for Android? I mean, is it JSON parsed faster than XML on Dalvik? And for the authentication I used to use PHP sessions and cookies when developing web pagers. Will be this also the prefered way to do it with the Android HTTP client? The other way I am considering is to give the client a token from the server after authentication and pass it in every POST or GET request to the server. This has the disadvantage of having to take care of passing it in every request, but on the other hand avoiding cookies should made the code simpler and easier to debug.

[android-developers] Changing hosts file on an Android device
Hi there, When I develop a dynamic web site I used to change the /etc/hosts file on my linux boxes and the equivalent on Windows ones to test the site on different browsers, so I add a line in the way of: 192.168.1.21devel.mysite.com So when I put http://devel.mysite.com on a browser, it connects to my development Apache server. So what I'd like to do it is the same on my Android device, I think I cannot edit /etc/hosts file on it at least while it is not rooted, but if there is other way to do this it will be enough. I know there are complexer ways to do this, like setting up a DNS server on my own network and give it through DHCP to the device when its connected to my WIFI access point, but I rather like to do it in a simpler manner if there is any... I use Eclipse for development, so if there is a chance to do something via DDMS or using command line tools like adb, it will be welcomed.

You will currently encounter devices with only 5 densities: 120, 160, 213, 240, 320. Every device will have one of those densities; 217dpi and 220dpi are not valid densities. You will care about this pretty much only for your graphics, though the platform will scale your graphics if it does. This is also relevant for text sizes and units used in layouts, but in those cases you just use sp or dp units and it is taken care of for you. So for your layouts you should basically not care about densities at all, just do your layouts in dp units as if you were on a medium density screen and let the platform take care of it for you. I strongly discourage the use of other units like in and mm -- many devices do not report the correct true physical density, so you unfortunately can't count on them working correctly. Fortunately you shouldn't need to, because 99% of the time you want to be operating in density units not true dpi.

You will currently encounter devices with only 5 densities: 120, 160, 213, 240, 320. Every device will have one of those densities; 217dpi and 220dpi are not valid densities. You will care about this pretty much only for your graphics, though the platform will scale your graphics if it does. This is also relevant for text sizes and units used in layouts, but in those cases you just use sp or dp units and it is taken care of for you. So for your layouts you should basically not care about densities at all, just do your layouts in dp units as if you were on a medium density screen and let the platform take care of it for you. I strongly discourage the use of other units like in and mm -- many devices do not report the correct true physical density, so you unfortunately can't count on them working correctly. Fortunately you shouldn't need to, because 99% of the time you want to be operating in density units not true dpi.

[android-developers] Re: Problem with Bluetooth after NFC Handover
Hi all,
Thank you!
I followed Vijay's reply to use Java reflection regarding Android
Bluetooth Profiles (A2DP and Headset) classes, I use SDK 15 (4.0.3),
which still keeps connect() methods hidden.
I also tried to follow Raunaque's advice, but no success with RFCOMM
socket although I used correct UUID (Service Discovery Failure
exception). I try again more attentive.
A solution for pairing I will look next is using bluez via DBus. I've
tried this approach on Linux from command-line d-bus utilities (http://
zitzlinux.wordpress.com/2011/02/28/connecting-bluetooth-devices-from-
command-line/) and got headset paired, I hope it can be done
programmatic in Android.
Best regards,
Alexei

[android-developers] PNG file won't display in ImageView when src is set programatically
I have a png file in my res/drawable-ldpi folder. I'm working in Eclipse with the emulator, but I've tried this on my 2.2.1 Android phone and I get the same behavior. I have an ImageView and I want to set the src programatically, based on a database call. If I just put src=@drawable.norusdpyr in the Activity's XML file, the file displays fine. BUT, if I put String imageresource = R.drawable. + parsedData[4].toString(); chart.setImageURI(Uri.parse(imageresource)); where parsedData[4].toString() = nor_usdpyr I don't see anything. I've also tried String imageresource = android.resource:// + getPackageName() + /R.drawable. + parsedData[4].toString(); chart.setImageURI(Uri.parse(imageresource)); and InputStream is = getClass().getResourceAsStream(/drawable/ + parsedData[4].toString()); chart.setImageDrawable(Drawable.createFromStream(is, )); and String imageresource = R.drawable. + parsedData[4].toString(); File file = new File(imageresource); chart.setImageDrawable(Drawable.createFromPath(file.getAbsolutePath())); and Context context = getApplicationContext(); int ResID = context.getResources().getIdentifier(imageresource, drawable, com.KnitCard.project); chart.setImageResource(ResID); finally even, chart.setImageURI(Uri.parse(android.resource:// + getPackageName() + /R.drawable.nor_usdpyr)); None of these work.

Is it totally out of question to choose correct resource id programmatically
(instead of using db values as-is)?
int resId = -1;
if (parsedData[4].equals(norusdpyr)) {
resId = R.drawable.norusdpyr;
}
// ...etc, etc….
chart.setImageResource(resId);
Asking since you're referring to resource drawables only which may be easier to
handle in this way. E.g. you get to choose error image for situations you
receive a value from db there's no existing image resource for.

[android-developers] LocalSocketAddress.Namespace.FILESYSTEM (?!)
I'm confused by the FILESYSTEM namespace. According to the docs, in Android's implementation of unix domain sockets these names refer to names in the Linux abstract (non- filesystem) UNIX domain namespace. But then there's a FILESYSTEM namespace, which implies that some of them could be non-abstract and be implemented in the file system, which is what I need.

[android-developers] Enabling accessibility in a WebView
Hi, I've been taking a look at accessibility in an app I work on. Most things are working well, but I was wondering if there was a way to enable support for TalkBack and KickBack in a WebView on any given activity or fragment. I know that the system Browser app supports screen reading when accessibility is enabled on a device, but this doesn't seem to do anything for pages loaded into a WebView. I've even tried the same page both in the browser and the WebView, but only the browser had accessibility working. If it's not possible to turn this on for a WebView, it is possible to implement the accessibility methods to get this working? It didn't seem apparent to me that this was possible based on the API docs. Thanks! -- You received this message because you are subscribed to the Google Groups Android Developers group.
