[android-developers] Application Startup Time.

2010-10-25 Thread Suneel Dasari 
Hi, I am working on a project which uses application start up time for
refreshing the cache.

if (cached_time_stamp  app_start_up_time) then
   use the network to get the data other wise use the data
from the cache.

But not sure how exactly we can handle this situation if the
application is paused. Handling it in onPause or onResume methods.

Any pointers would be of great help.

Thanks in advance,
Suneel

[android-developers] Error while parsing the JSON response.

2010-07-09 Thread Suneel Dasari 
Hi I am getting the below error while parsing JSON.

MY CODE:

Overridden method in POJO RootCategories;

public String toString(){
return Category ID:  + catId
 + Category Name:  + catName
 + Description:  + description
 + isPP:  + isPP
 + isRootCategory:  + isRootCategory
 + isTerminalCategory:  + isTerminalCategory;
}

Parser in my Activity:

private ListRootCategories parse(String jsonString) throws Exception
{

java.lang.reflect.Type collectionType = new
TypeTokenListRootCategories() {
}.getType();
ListRootCategories rootCategories = new
Gson().fromJson(jsonString,
collectionType);
return rootCategories;
}

Please help

Thanks
Suneel

[android-developers] ANDROID: How to load the images from a URL in the Grid.

2010-07-09 Thread Suneel Dasari 
Hi
  I have been working on a POC, where I have an activity which
displays a group of images from my local drawable folder in a Grid
view. I have created the ImageAdapter and that has actually an integer
array with the image ids and it is working fine.

But the actual problem is I have to read the image which resides in a
remote server through a URL and display it in the Grid.

Please help

Thanks
Suneel
