Android :: What Mechanism To Ensure Request Comes From App?
Sep 17, 2010If I have my app fetching content from my server, what mechanism should I use on my server to ensure that its my app making the request? Is there any way that I can sign the request to using my app's signature to show its come from my app and not from a stolen version or copycat?
View 4 Replies View RelatedAndroid :: Sensor Data Poll Mechanism
Jun 3, 2010Per the current implementation in Sensor Manager, the SensorThread is polling data per below code, final int sensor = sensors_data_poll(values, status, timestamp); it then checks the sensor type if it is registered and processes the data further. For an application which has registered for only one sensor, still to get that particular sensor data, SensorThread has to execute for atleast N-1 loop most of the time. Can anybody provide the insight as to, why SensorThread is waiting to check the sensor type to be returned by the HAL instead of sending sensor information which is currently registered by that application. Wouldn't that increase the performance?

Android :: XSLT Transformation Or Other Mechanism For Converting SVG Drawing?
Jun 3, 2010I'm wondering how vector drawing in Android with the Shape class may resemble another vector drawing standard. Since Shape is a Drawable, and Drawables are usually defined as XML, it sounds a lot like the vector drawing commands in SVG. My question is this: Has anybody created an XSLT transformation, or other mechanism, for converting an SVG drawing description into Android Shapes?

Nov 9, 2010What I need is to perform some network operations in background inside a service. I want them to run in a service because, as pointed out in the "developing rest client application" talk from google io, I don't want to loose the result if the activity is brought in background. What sounds quite obvious is to use an Intent Service, and get the result as a broadcast. In this way I am sure the service will die and no consume any other resources when its done, but I need to convert the actions I want to perform to intents and back. Well, I was now wondering if it makes sense to bind to the service instead, at least for getting the result. And a more general question: is the bind mechanism suitable for one shot services, or it just make sense for persistent services? What happens if I call the startService method but the service is already active? Will it start another service, or will it call the onStartCommand of the same service? I am asking this because if I use "regular" non sticky service, it could happen that I need it to perform some action and I don't know if it is already active (and I don't want to have a queue of action waiting for onServiceConnected to be called.

Jan 4, 2010I currently have a lot of problems with this error. I programmed a widget and a service that runs in the background. This service is updating the widget on different occasions (position changed, screen turned on, timer based...) with images and text it's loading from a server. After a couple of updates I always get an error from the JavaBinder, at least that's what DDMS says. Reproducing the problem with my app is quite easy but I just can't figure out what's going on there.

View 2 Replies View RelatedAndroid :: Remote Service Returning Value From Http Transaction
May 6, 2009I've been researching how to best implement a service which performs a network transaction and returns data to the caller.
Clearly, this needs to happen on its own thread which means some form of async response. I can see at least three ways of doing this--some more complex than others. In the descriptions below, C is the caller, S is the service.
1) C wraps a Handler in a Messenger object, adds this to an Intent. C then calls startService with this intent. S extends IntentService which runs the Intents received in a worker thread. S then sends a message to C via the Messenger. This has the benefit of not requiring any of the async binding process or making an IDL interface that needs to be compiled into C. This seems to be the closes to a Handler-based response mechanism of Local Services.
2) C binds to S and then uses AsyncTask<> to make a blocking call to S. S performs the network transaction and returns the data in the return value or an out parameter. This requires the async binding process, but does not require a callback function since the inter- thread communications is handled by AsyncTask<> and the worker thread is in C's context.
3) Make the function called in S be completely asynchronous. S defines two interfaces: IMyService and IMyServiceCallback. S implements IMyService.Stub. C implements IMyServiceCallback.Stub. C binds to S then calls S via IMyService, passing its IMyServiceCallback binder. S spins up a worker thread and returns immediately. S then calls the callback when it has completed the network transaction.
I am asking for advice on which methods are most appropriate. I do not need the the service running constantly, only when the web transaction is required. C does not use S all the time--definitely don't want to bind during C's onCreate. However, I would like the time from when C determines it needs to use S to getting the results back to be as quick as possible (i.e. adding minimal latency to the already latent network access).
Is there any preference to having the worker thread in C or in S? Are there any significant problems with option 1?
Android :: Failed Binder Transaction When Returning Camera Image
Feb 15, 2010I get the Failed binder transaction error in the logcat when returning the image taken with the camera from the camera intent back to the parent intent (as a byte[] using putExtra). I don't understand why, its not like its a big bitmap or anything. It only happens when i take pictures with lots of light, because then the byte[] is bigger. The error occurs when leaving the camera intent. Does anyone see a mistake in my code?
Here is the code of the camera intent:

Feb 16, 2010I have a problem with an app that lets the user take a picture. I've posted it on some forums already, but nobody seems to recognize the problem. Hopefully someone here knows a solution :)
I've put the code of taking a picture in a seperate activity. Then I call the camera intent from my main activity using activityForResult. In the camera intent, I use putExtra to return the camera image (as a byte[] without doing anything to it). But when the program transitions back from the camera intent to the parent intent that called it I get a Failed Binder Transaction error in the logcat because the byte[] is too big. But I don't understand this, because the image is not even taken using the maximum resolution :S
The code of my camera intent is:

Android : Content Provider Vs Direct Database Access - Transaction Management
Aug 7, 2010I understand, at least on paper, the basic difference between the Content Provider and just directly accessing the SQLiteDatabase. I have a functioning prototype for my application, and currently it is just directly hitting the database. I don't really have any experience using the Content Provider pattern, but I have found out that I will need to share some data with another application.
I will only be sharing about 2 out of a dozen or so tables, so I was wondering if I should be just completely redoing the data layer to follow the Content Provider pattern, or just expose only those tables via a Content Provider for the sake of the other application and still directly access the database in the primary application.
One of the issues I ran into with my prototype was that I have some fairly complex transactions, and the code I wrote to get that working is not designed particularly well and isn't reusable at all. As I add more functionality to this app, I'm going to need a better designed data access layer, before I set off writing my own, does anyone know of any good resources with design patterns for this type of thing already? Also, if I need to go the Content Provider route, am I going to have solid control over the database transactions?

Activity Vars NULL After In-app Play Store Transaction?
May 31, 2012I've managed to incorporate in-app billing into our product but it is failing on one of my two test devices - a Samsung Vibrant / Galaxy S running Android 4.0.3
The transactions themselves are confirming - reserved product ID's and our actual product ID's - but on this particular phone once the response code is received and the app's activity is brought back into view, several variables holding operation-critical values are NULLed out, crashing the app and preventing actions associated with the purchase.
This DOES NOT happen on another test device - an HTC Sense running Android 2.3.4.
Both devices are running Play Store version 3.5.19.
At a loss right now for trouble shooting. If there is a way to extract the product ID from the signedData bundle returned from the Play Store it would be a way for me to side-step the problem.
