[android-developers] binding to a service from a separate class
Hello Android Devs, I've created a timer service (because I want the timer to accessible, persistent, and run when the activity is not up), tested using a basic front-end activity. The service and call backs all work fine, now what I want to do is marry the service up to my timer view class. My timer view class extends relativelayout. I have an activity which inflates and adds the timer class to the view. What I'm trying to do is have the class bind to the timer service and get updates via callbacks. The problem I'm having is that bindService() is undefined, I think this is because it's not part of the activity. If I pass the constructor the activity context it does compile and run, however it crashes every time. Plus, it's a bad idea to use context in this way. The interface is 2-way, I send commands from the view to the service and it sends timer and state updates back. I could use intents for this, however that's clunky and wastes resources. I could also have the activity itself bind to the service, but I'd prefer to cut out the middleman. How do I approach this problem? -bb -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Use shared preferences on non-app directory file
Shared Preferences is a handy tool, the only problem is that as far as I can tell it only works on files in the app directory. Is there a way to use shared preferences on a different directory? I've tried simply putting a path in the file string but that crashes. -BB -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Use shared preferences on non-app directory file
I understand your point, however as a developer I have a problem that needs fixing and this is one of the possible solutions. When google provide me a way to create demo and licensing algorithms that cannot be defeated by the user simply clearing the app data then I'll stop trying to find a way to create a persistent file.

Even with stock LVL the user can still clear the user data as it uses Shared Preferences. Using the SD card is a good idea whether you are using LVL or not. LVL is a sledgehammer to crack a nut in this case.

[android-developers] Re: CountDownTimer doen't work during device in deep sleep?
This is by design and it's to save battery life. If the phone cannot sleep then the battery will discharge very quickly and your app will be a battery drain. I was coding a timer myself and Mark recommended that I use notification manager for long-term timing instead and it was good advice. I suggest you re-think your approach. Here's a brief summary of the approach I took: When an android device sleeps onPause is called in your activity. Override onPause and create notifications for the events you are timing, and save the timer info into shared preferences. When your device wakes onResume is called, in Override onResume and set up the countDownTimer calculating time left using the values from shared preferences. This approach means you have more work to do, you must learn notifications, you must create intents that deal with the notifications, etc. However it will make as better end product. Hope this helps, -BB On Dec 22, 10:54 pm, optimusgeek wrote: > I use CountDownTimer for counting 24hours with 1minute interval. > but It seems that the onTick() not called when device in deep sleep. > When I check the millisUntilFinished value after activating device, > The value was not match first but after few seconds, It show correct > value. > I think, when device in deep sleep, handle message from CountDownTimer > delayed, and if device activated, the last message of CountDownTimer > sent. > and after that the millisUntilFinished value is updated. > > Any solution for it?

[android-developers] Re: LVL "LICENSED" Test Respone
I think the thing to do is simply not use the google extras. Why do you need them? All you really need to know is whether an application is licensed or not licensed. Google may say that the verification time of the licensing is 2 days say (I have no idea what the normal response would be), but why use their values? The same goes with retries, just use your own values then it doesn't matter whether google sends extras or not.

[android-developers] Re: Android Market Licensing Problem
I recently did my own LVL implementation and I can tell you that tracing these issues down is a real pain. First you need to put loads of logging into the LVL code to find out what the actual response is, otherwise you have no visibility, then you have to put logging into all the code between the response and the allow/dontallow callbacks. Basically what I found was the stock code was unworkable in many ways. I quickly came to the conclusion that I needed to modify it into something that worked for me. There's a few reasons behind why you should abandon the stock code: - if you use the stock implementation then crackers will find it very easy to circumvent - as you have found it is very hard to debug. You have to spend so much time figuring out how it works you may as well roll your own instead. - who's to say whether the google responses are what you want? How many retries do you want before it sends a dontAllow back? Maybe you want to treat the error responses as a retry. Do you want google to specify that or yourself? Do you want them to specify the time between checks? It's better to take control of this process so you know exactly what is going on and you can manage the user experience. In the system I came up with in the end all I use is the response and none of the extras. What I do with the response is all custom, that way I can use the market test responses in development without issues. -BB On Nov 13, 4:40 am, John Gaby wrote: > I am using pretty much the default Android Market Licensing in my > application, but find that it is not working correctly on most of the > devices that I have tested.

[android-developers] Re: Android Market Licensing Problem
You can't, basically. All you can do is publish and hope their system works. My answer to this problem was to not use the response extras and to create a system that can deal with an incorrect response here and there.

[android-developers] prevent user from clearing app data
It looks like there's a bug on Froyo where the user can clear app data even if allow clear user data is false in the manifest. I would like to put out a demo that stops working after a certain amount of usage and the simplest way is to put a counter in shared preferences (or another file) somewhere, however if a user can clear the data then all that he/she would need to do is clear the app data every time the app locks. If there a way to put this data into a file that the user cannot delete? Or should I just get my demo out there and hope that this bug get plugged? -BB -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Overlay to make parts of image clickable
I have an image and I want to make parts of it clickable. From my research I can see 2 ways to do this: 1) I could chop the image into pieces and put them into a relative layout 2) I could create a matrix of points that describe the clickable areas and use onTouch events to track clicks Option 1 has the drawback where you have to make areas square or rectangular, plus alignment and scaling are a pain. Option 2 can be scaled easier however I'm not sure how to go about coding it. Am I missing any possibilities? Are there any tools or source code that would make it easier? -BB -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

In other words there's no way to protect my app from the user simply deleting app data, and the only solution is for me to build my own licensing server? Thanks google, you guys think of everything.

[android-developers] XML encryption
Hello Developers, One of my apps uses custom xml files for much of the data used by the app, I'd like to encrypt the data as part of a copy protection plan and I would like some views about how best to go about it.

There are two methods I can see: I can encrypt the whole file and decrypt it during the activity setup or I can encrypt the data in the xml entries.

[android-developers] Re: XML encryption
I'm not sure if that is practical. If I created a public/private keypair as part of the app it would be accessible to the user and could be used to decrypt the data. The only way that would work is if there was a way to protect the public/private keypair, and I'm not sure how to go about doing that.

I'll have a look, thanks for the suggestion. The trick will be to hide the key in such a way as to make it difficult to find, I'm hoping a combination of proguard and additional obfuscation of my own will do the trick.

[android-developers] using long touch to set a seekbar
I have an app that uses seekbars with buttons on either side for fine adjustments. Right now I use simple onclick events for the buttons, every click changes the seekbar 1 unit. What I would like to do is use a long press to quickly scroll, so if a user holds down a button for say 800 millis it will start adding ten units per second. What I'm thinking my approach should be is to use onKeyDown and onKeyUp events, but is there a better way? OnLongClickListener won't work as far as I can tell because it doesn't detect key-up. Is my approach correct? Thanks! -BB -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

Actually, upon further review I think I misunderstood key events, I don't think that approach is right at all. It looks like I will need to use touch events.

[android-developers] Re: using long touch to set a seekbar
OK, I solved this myself by attaching an onTouchListener to each button and listening for ACTION_DOWN and ACTION_UP events. the only problem is that if a user moves their finger off the button while holding it the ACTION_UP event is lost. This doesn't seem to be a major problem as all they have to do is tap the button again to stop, but if it gives any trouble I'll simply have to add a generic ACTION_UP listener. Hope this is useful to someone, -BB On Oct 12, 11:25 am, bagelboy wrote: > I have an app that uses seekbars with buttons on either side for fine > adjustments.
