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">

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]

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)

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;...................

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?

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.

I'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

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?

I have an instance of Bitmap that I want to load into the WebView. How can I do this? I do not want to call webview.loadUrl() as the image is already loaded from the file into memory . I am trying to optimize my code. I can see webview.loadData() however, seems like I have to encode Bitmap into UTF-8?? I have two questions: 1) How can I use webview.loadData() from a Bitmap instance?

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?

This is the code i have implemented for loading 16 bit data:
GLES30.glTexImage2D(GLES30.GL_TEXTURE_2D, 0,
GLES30.GL_RGB16I, ImageWidth, ImageHeight, 0,
GLES30.GL_RGB_INTEGER, GLES30.GL_SHORT, pixelBuffer);
I have succesfully created Image Texture using GL_UNSIGNED BYTE with 8 bit data. But failed when using GL_SHORT using 16 bit data.

I am developing an application in which the user require to register first and than got the user page. For that i have made layout and the layout consist many fields, so, i have made part of layout and also made the separate activity for the each layout. The layout like address, phone, etc... After that i have wrote the code for calling an activity and it works fine. It means when i press the "Next" button the another page will come and it will also consist some textview ,edittext and previous and next button. Actually, i want something different like -- When the user fill the first form and he will proceed to next, the content written by the user should not gone when the user press "Next" button. The content should be there which was written by user. And same way i have have 6 pages like that way to complete the registration process. So, have you any idea to solve above problem? I really need your help because right now i stuck at this point. So, please any body help me out of this problem. I would appreciate your help. I am waiting for your reply.

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.

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?

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.

In my app, I am using below code to obtain all contacts with PHOTO_ID:
CODE:.............
The app has a list view to display all contacts and use the ContactPhotoLoader in the stock contact app to load the contact photo async. When running, some contact photo can be displayed correctly and some cannot.
When clicking on the list items, the app will start the view contact activity of the stock contacts app:
CODE:..............
For the contacts, which photo cannot be displayed properly, is able to display correctly in the stock view contact activity. I have compared the source code of the stock contacts app and my app. They are doing the same thing basically. I have also checked for the permissions used by my app are covered the set of permissions used by the stock contacts app.

I'm working with Eclipse and writing an Android application. I've noticed that the load times to the Android emulator can vary significantly. Recently, I found that manually going back to the main menu of the emulator helps my application load much faster.Is there a quicker way (read: automatic way) to exit out of my application rather than hitting the Back button multiple times until I get to the main app menu? Secondly, is there something I am doing wrong that factors into the longer load time?

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.

I came across an interesting issue when testing android 2.2.
My testing was to use webview api,webview.loadUrl(url);
If url is from any public domain, ex, www.google.com, the web content is rendered very well.
[url]
If url is from local host, ex, tomcat with port 8080, the web content is rendered as well.
[url]
But if url is from other port, ex, websphere with port 9080, the web content is not rendered.
[url]
There is no exception thrown, and it shows blank on the emulator.
Is there any setting needed for different port?

to start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.
But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.
