Android : Checking 3rd Party App Compatibility Using CTS
Feb 8, 2010
I wanted to get the info on the following query, could you guys please help me in getting the answer?I have set of platform api those will be tested by CTS to check compatibility, and I am making use of some 3rd party api in one of the platforms api. Suppose if I am changing or modifying the 3rd party api (to suit some of my requirement), is CTS is capable of telling whether compatibility is broken in the 3rd party app?

I would like to check whether there is any direct API available to check whether a particular Database exists or not ?
Currently, to initialize data for the first time (not repeatedly), we try of open the db and if it fails we know the database does not exists otherwise it is already created and initialized.
Is there any simple API available to check whether DB exists or not ?

I am working on a simple app for the HTC EVO that blinks the alternate notification LED when a new text message is received. I have this part working great via a Broadcast Receiver but I need some way to turn the LED off when the user has read the message(s) using their default SMS app. I'm not sure if it is best to do this in the receiver or in a background service.

Anyone know how to check the user's country? I'm looking for a way that's faster than using GPS and reverse geocoding. (I need the country where the phone is registered, not their current location, in any case.) Is there any constant in the settings?

Is there a way to programmatically without root check and see how a program was installed?
The only solution I've been able to find is using root - and tapping into a database that the Vending application uses;
CREATE TABLE assets10(_id INTEGER PRIMARY KEY AUTOINCREMENT, content_uri TEXT, s tate TEXT, download_pending_time INTEGER, download_start_time INTEGER, install_t ime INTEGER, uninstall_time INTEGER, size INTEGER, type TEXT, package_name TEXT, is_forward_locked TEXT, signature TEXT, refund_timeout INTEGER, version_code IN TEGER, server_string_id TEXT UNIQUE);
Most specifically I can check to this database using my package name and/or signature and see if it's ever been installed by the market. Then if it has you could check to see if it's been uninstalled.
As for background, I'm just messing around with ways to distinguish real users from pirated versions. I've noticed from an application I've posted that I only have approximately 100 downloads and 50% active, yet my server which is used by the application shows approximately 200ish unique users within the past few days.

I have a string called extStorageDirectory which is set to my SD Card and then "/mypics", I can then save a picture in to this directory, but only if the directory exsists. So how do I check to see if the directory exsits, and if it doesn't creates the directory?

I am doing an experimental project and want to send key events from one application to another. I know android doesn't allow applications to interfere each other in this way due to security concern. Is there any way i could bypass the security check? I've looked into the WindowManagerService class and made some modifications but it seems not working for me.

I have an IntentService which makes some web service calls. Before making these calls I check to make sure the device has network connectivity.
I am doing so like this:
CODE:.............
Unfortunately, when I'm debugging on my Android device, this returns false when I have both a network and a wireless connection.
Some interesting tidbits about connec.getNetworkInfo(0):
CODE:...................
Clearly this code is not sufficient (perhaps it would only return true if I sent some bit over the network and turned the radio on?). Moreover, since I'm not well versed in the ConnectivityManager, I'm assuming I should probably be scanning all networks (ie: getNetworkInfo(0 through N)).

Actually I am checking the code flow of NFC in Android-ICS.But i got stuck because of some files are not present in ICS.
Like :
GB code -> WriteTagActivity (to write into a TAG)
ICS code -> no files.
Some more files are also missing in NFC and TAG.

Since I got my 16 GB Card it's started saying it for longer than with my 2GB Card, however it says it less now. Does how long it takes depend on how much data you put on since taking it out of USB Mode? Because when I first got this card I wrote a lot to it (Moving all my files over), but now I just put a few files here and there on... Is there a way to disable this and let you run it manually at your leisure?

I have a terrible bug in my widget. The widget is waken up using an AlarmManager (the update interval is chosen by users, ranging from 30 mins to 2 hours) to grab some data from the Internet and display it on the widget. I do not hold a wakelock since if the phone sleeps, just let it sleeps. There's no way to update the information since nobody will see it. If I put the phone in the basement (has no wi-fi or cell signal) for about an hour. the phone will definitely not update anything. However, when I get it back from the basement, the cell network could never be recovered again no matter how long I have waited (it just get an X on the cell signal icon on the notification bar) that I must restart the phone. May I know if a partial wake lock must be held on checking network availability?
Find the code skeleton as below:
CODE:.................

I wanted to check the availability of another app in Market from my app. Based on this I will have to give a message saying "Coming soon" or show the other app in Market. I am using the following intent
new Intent(Intent.ACTION_VIEW, Uri.parse("market://details? id=com.example.android.XXXX"));
Now, how can I catch the result which would say if the Market was able to find this package or not?

I got problem with register. I use an if-else statement to check whether the user left any blank. If there is any blank, an error message will appear. The problem is, even with no blanks, all filled up, the error message still appears and thus prevents user from registering. I can't find any error.
Please help me spot my error.

I am fairly new to Android (find it most fun, btw) and I was wondering...
How can I create an Android CheckBox with the label to the left and the checking button/box aligned to the right (pretty much a switch of the way this widget is drawn by default)? Like the way a checkbox preference normally looks like...
I am looking for the most elegant/short-coded version possible, if there is one. I mean other than creating your own View/ViewGroup with layouts, empty-labeled CheckBoxes and TextViews, etc...

I'm writing a game for Android. I'd like to target as many devices as possible. I'm aware that Droid owners buy about 50% of the apps and the rest are a mixture of G1 and HTC devices. So far, I've been testing my app in the emulator set to model the Droid phone (where I get about 40 fps) as well as on an actual Droid phone (where I get about 60 fps).
I'd like to know how fast my app runs on slower devices such as the G1. Is there any way I can do this besides getting a G1 myself or asking people with G1s to test it for me? For example, is there any way I can use the emulator to get a rough idea how well it will run on the G1?

After you give an app permission to auto-update, does anyone know how often it checks for a new version of itself? Does the app check daily and if an update is found (and provided it does not alter the permissions) apply it? Is it possible to alter the frequency that it checks?
I ask because I just opened up the Android Market and right as I did so it suddenly started updating half a dozen apps. Now that was fine, since they all had been given permission to auto-update, but I want to know if they only check for an update when the market is opened, or if it was just a coincidence.

I am writing a screen scraping app that reads out various pages and extracts the data. I'm using the SAXParserFactory go get a SAXParser which in turn gets me an XMLReader. I have configured the Factory like this. code...
I can understand that it can't find the entity, since I told the factory to not read the DTD, but how do I disable entity checking altogether?
EDIT: This is for an Android app, which is why I am reluctant to use an API/library that isn't in the standard environment.

So I have everything set up to automatically use my Google Voice number now, and started getting SMS texts in both my messaging inbox and in GV. I figured out I needed to turn off the SMS forwarding in GV, but it turns out I like using the default messaging app more than the one in GV.
Is there a way to make the GV app stop checking for SMS messages but still download my voicemail? I don't want to make it stop checking all together but I'd like to use the other app for SMS's.

<supports-screens android:anyDensity="false" android:largeScreens="false" android:normalScreens="true" android:smallScreens="false" android:resizeable="false"></supports- screens>
first of all what is the resizeable attribute? It does not seem to be documented. This is working almost 90% for my game except when testing in WVGA screen resolution, all my images are scaled incorrectly, it is longer vertically than horizontally. I was expecting the screen compatibility to maintain aspect ratios as that of HVGA.
Also in my layout I have a scrollview and it is designed in such a way that in HVGA when it is not scrolled down, the items are hidden away, however now in WVGA those things are shown. If the aspect ratio of HVGA is maintained I won't have this issue. How can I make sure the aspect ratio is maintained? Also in my layout I am positioning some items using pixel positions. Should I convert these to dpi? How do I calculate what dpi they should be?

What is the recommended approach to have currently shipping 1.5-SDK compliant apps to start offering 1.6 features (such as TTL) in the Market? Can we just publish 2 versions of the same package name each compiled with a different SDK level (will the Market automatically push out only the right version of the app) or do we have to use different package name and assume that the user will find a way to understand the version of the OS he has. A public statement to the developper community would be more than welcomed here!

I've found again my DevPhone1 (aka G1) on a shelf and though that this time I should really give it a try and create an app for it. But I've really lost touch with the Android world and now I don't know where to start really. There have been many SDK releases lately for many new and better devices. Which one of these can I use with G1? What is the most recent one which can be used on that hardware (although with reduced performance) but which will enable development for rather modern Android releases as well. The firmware update received today, while recharging the phone, is 1.6. Can I go higher with some R&D build?
