Android :: Rapidly Load Data On Relaunch Of Activity

Nov 12, 2010

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. [Note: I want to do to make client happy by decreasing the loading time and running the application efficiently and optimizing application's loading time]

Android :: Application Gets Name Of First Activity In Which Load Data

Mar 14, 2010

I think i'm getting senile because I was convinced that to give a name to your application, you had to fill this part of the manifest: <application android:icon="@drawable/icon" android:label="MyApplicationName"> However for a reason I don't understand, my application gets the name of my first activity, in which I load data, henceforce, It is called "Loading"...(defined as follows in the manifest) <activity android:name="AccueilSplash" android:label="Loading">

Android :: Adding Data To Intent Fails To Load Activity

Apr 11, 2010

I have a widget that supposed to call an Activity of the main app when the user clicks on widget body. My setup works for a single widget instance but for a second instance of the same widget the PendingIntent gets reused and as result the vital information that I'm sending as extra gets overwritten for the 1st instance. So I figured that I should pass widget ID as Intent data however as soon as I add Intent#setData I would see in the log that 2 separate Intents are appropriately fired but the Activity fails to pick it up so basically Activity will not come up and nothing happens (no error or warning ether)

Android :: Activity / Process Lifecycle - Save / Load Data To / From Disk

Nov 26, 2009

My app is made of two activities, A and B. I'm considering this sequence of steps: Activity A is started. A launches B [A is paused, B is running]. B launches a map intent [A and B are both paused now]. Now the user is using the maps application and the system decides it needs more memory. Can the system kill only one of my activities for memory, or will it always kill all activities in a "process" in this situation?

Both activities share some static data like:

class Data {
public static String mName;
public void save() {
// write to file: mName;...................

Android :: Possible To Load A Layout XML At Runtime And Load Into Activity?

Sep 4, 2010

Is it possible to load a layout XML at runtime and load into activity?

In my app, I have various types of data like Person, Company, City, etc; The requirement is to dynamically load the layout, find views by tags (property names like Person.name, Person.address) and then fill in data. For example, if user has selected an object of type Company, we want to load a company.xml layout, inflate it and then associate various properties (company name, company slogan, city, address, revenue) to tagged views. One possibility I see here is - each view in the layout will be associated with property-name as tag and then appropriate data will be loaded in appropriate views.

What should be the best design you would recommend?

Android :: Activity Does Not Load After First Run?

Apr 24, 2010

This is a silly question... but after following the instructions and running my application, I can't get it to run again. I hit run, the emulator opens up, and nothing happens at startup. When I attempt to launch the app from the applications menu, I get the old version of the app. Breakpoints etc. don't seem to do anything. Tried creating a new project altogether with different names for the activity, etc. and running that, still nothing.

Android :: Need Program To Not Relaunch

Aug 6, 2009

I have a question about the activity cycle when you use the Home button to exit an application. I have noticed that when you use the Home button to exit an application, you can hold the Home button to move back to that application, but selecting that application from the list of programs or the 'desktop' will open a new instance of it. So I'm wondering is there a way to make it so that if the program is running already, then it will move back to that application like it does from the task menu brought up from holding home button? Or is this something that needs to be handled via the activity methods (such as on Create, on Resume, etc) or in some other clever way?

Android :: How To Relaunch Application From Intent

Aug 17, 2010

I would like to put a notification with an intent. My intent is basically action = DEFAULT and category = LAUNCHER in order to bring the activity that was launched into the front. When the app is not shown, there is no problem, the intent works perfectly and launches the last activity seen but when there is already an activity launched, on New Intent is not called (activity is in single eTop mode). I'm wondering how to relaunch the app from an intent to the last activity seen and call on New Intent when the activity is already launched.

Android :: Activity Timeout On WebView Load

Aug 3, 2009

In my app I have to load external page into WebView-based activity. Some of my users with slower connections are reporting screen timeout while waiting for the page to load. What would be a good way of loading the page on backgorund thread and then refreshing the screen? Use HttpClient to fetch it and then use WebView#loadData? My fear is - the page I'm loading is pretty complicated there's some JS that happens on load - wouldn't I just mess it up? Is there an alternative way of doing what I need?

What's the easiest way to populate a SQLLite table with data off a URL?

I'm writing a Delphi web app that will generate a file on a server for my Android app to download.

In Delphi, I'll probably save it as a .csv file and use bulk import to import into MS SQL Server.

What's the easiest / best practice way to do this in Android? How would I download the file from the URL and then load it into SQLLite?

Android :: Don't Need Previous Activities Load On Pressing Back Button On First Activity

Jul 15, 2010

When i leave my app after pressing home button and then re launch it from menus it behaves in a strange way.Sometimes it launches the same activity on which i pressed home button.But sometimes it launches the first activity of my app. One reason for this could be that whenever system has memory shortage it clears any activities existing in But the strange thing is if i press back button from first activity it takes me back to the same activity on which i pressed home button and all other previous activities are also there(like if i press back button again previous activities also exist.)I haven't set any launching mode for any activity in my app(like single instance etc).What i don't need is that previous activities load on pressing back button on first activity.

Android :: Voice Recognition Activity Called In OnCreate Method / Causes App To Load Slowly

Oct 1, 2010

In my android app I call the voice recognition in my onCreate method of my startup activity. I have made it a preference to start up with the voice control or not. However, the app takes about 5-7 seconds to load when voice recognition is on. When it is off, the app starts almost instantly. Below is sample code, I have added Free_Form, max_results 1, and a custom prompt to mine.Why would calling the normal android speech recognition take sooo long to load in my OnCreate method?

Android :: Unable To Start Activity - Load Home Screen Or Show Notification During Calls

Dec 18, 2009

Has anyone been successful showing a notification, starting an activity, or loading the home screen *during* a call on the Droid? All three of these actions can be done with the emulator running 2.0, but will not run from the Droid. I don't receive any type of notification that these actions fail on the Droid. Although, every action works when a call is *not* active. Missed calls during a call *do* show up in the notification bar, so I am hoping there is a way.

I understand that the notification bar can not be accessed by users during calls, but it would be nice if a notification could at least be delivered. I also understand the security and usability concerns of displaying a window or action during phone calls. Although, there are a lot of users who would like actionable functionality based on calls.

HTC Desire :: Internet Connection Failed To Load Data With 2.2

Sep 10, 2010

I would like advice from those with 2.2 on Orange. I've had my Desire for 2 months now and love it-apart from one thing-the damned Internet connection. Quite often, with a strong 3G+ (HSDPA) signal, my internet connection fails to load data. Then, a few minutes later, in the same location, it works perfectly. I know for a fact that this is not a network only problem. The reason I know this is because I previously used the exact same SIM in my iphone for 6 months in the very same locations and it always worked perfectly.

Therefore, my strong suspicion is that the problem is a result of the combination of the Orange branding on a Desire and the network itself. I'm sure I read of a couple of posters here who had the very same problems and when they moved to 2.2 the problem disappeared. Can anyone confirm? I've been waiting patiently for the Orange update to 2.2 but am getting fed up and I'm concerned that the Orange bloatware may still cause an issue after this. Hence, I'm considering a debrand and update myself.

HTC Incredible : Com.htc.launcher Crashes / Rapidly Drains Battery

Nov 17, 2010

Normally I wouldn't worry, but when it does crash, and I'm not paying attention to my phone, it suddenly sucks the battery big time. If it happens overnight while I'm sleeping, the battery will be dead. I just checked my phone now; last check was about 2 hours ago, it was at 90-odd percent, and now it's at 55% and com.htc.launcher is asking to be force closed. I check my battery usage, and sure enough, it's the culprit. My phone is also very hot, perhaps because it's overusing the battery. I want to avoid a factory reset. Is there any solution or known cause for this problem?

I guess the Seido battery was not the problem. The battery was fully charged before I left yesterday, but it was drained completely after being off the charger for only 16 hours..5 of them I was sleeping. I do not have the GPS on...etc..None of my setting on my phone changed. I am not sure why the battery is draining so rapidly.

Samsung Vibrant :: Phone Start Shocking Rapidly (Electricity Static Or Something Else)

Nov 5, 2010

My Vibrant started shocking me today! At first it was just a shock here or there. I figured it was just because of static electricity, but as I went to pick it up a few minutes ago it wouldn't stop. It shocked me about 3-4 times very rapidly. Is this normal? It is plugged in via USB to my laptop. I'm still within the 2 week period, so I can go back and return it to Wal-Mart, but this is my 2nd vibrant I would be exchanging!
