[android-developers] Re: Different layout for Different screen sizes.
I doubt the density of the device you are playing with. I would suggest you to check the density of the device by using: DisplayMetrics dm = context.getResources().getDisplayMetrics();int densityDpi = dm.densityDpi; Check for more info: http://stackoverflow.com/questions/3166501/getting-the-screen-density-programmatically-in-android On Wednesday, 23 January 2013 11:51:14 UTC+5:30, sree wrote: > > Hi, > i am implementing UI design for samsung S3 and nexus S.when i am run my > project compatability of screen is change. > i am using separate layout in res folder like layout-sw240dp(Nexus S), > layout-sw320dp(S3).when i am running these both devices are take > layout-sw320dp xml file. > > can help any one for these problem. > thank you in advance > -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Android - How do we make notification visible once application is installed?
Hi,
As per my this question, i have written the below code to show
notification and also made a notification steady at the notification
bar.
private void showNotification()
{
CharSequence title = "Hello";
CharSequence message = "Notification Demo";
NotificationManager notificationManager =
(NotificationManager)getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"A Notification", System.currentTimeMillis());
Intent notificationIntent = new Intent(this,
Main_Activity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this,
0, notificationIntent, 0);
notification.setLatestEventInfo(Main_Activity.this, title,
message, pendingIntent);
notification.flags = Notification.FLAG_NO_CLEAR;
notificationManager.notify(NOTIFICATION_ID, notification);
}
But, is there any way to make a notification visible once the
application is installed in the phone? I think there should be any
scenario/method/file in which we can write this code and notification
will be visible as soon as the application gets installed in the
phone.
Again i am taking an example of "yahoo mail" application, in the same
application, once we installed the yahoo application, the notification
is appeared with icon at the same time.
Please share your ideas and suggestions.

[android-developers] Rapidly load data on Re-launch of an Activity
Hello all, Actually, i am fetching XML from the web, parsing it and display it on the screen. The problem which i am getting is that the activity tries to load the data from web each time the activity is called.(Actually, my mobile app requires frequent trips to the server) So i am in search of the below solution: On Re-launch of an activity, the data from web should not be loaded again. (But it should load data from the cache or local database that we have created while calling the web-xml for the first time). creating a class that i can use to transparently make application faster by selectively caching items in memory. And thus, making users very happy and This class can even apply individual refresh times to each cached item. So, i think i need to store the data in Cache , or in local database or something like that. Is there any way/technique to implement such thing ? so that it need not to load from web every-time on Re-launch of an activity.
