Android :: Way To Pass An Object Array To An Activity
Nov 15, 2010I have read posts on passing arrays from and to activities, but I am confused as to how I would do it for my specific case.
I have an array of objects called DaysWeather (a DaysWeather[] array) where the objects have several String attributes as well as a bitmap attribute. I read somewhere that you have to make it serializable or parceable or something, but it seems messy at first glance.
Could someone lead me in the right direction?
Is there a simple way to do this?

View 2 Replies View RelatedAndroid :: Converting Byte Rgb_565 Array Into Argb Or Rgb Array
Jan 12, 2010I have Picture data in byte rgb_565 array, and I want convert it in a productive way into argb array. Right now I have found only one (little slow) way to do this: Bitmap mPhotoPicture = BitmapFactory.decodeByteArray(imageData, 0 , imageData.length);
where imageData is my byte[] array in rgb_565, and then: int pixels[] = new int[CameraView.PICTURE_HEIGHT*CameraView.PICTURE_WIDTH]; mPhotoPicture.getPixels(pixels, 0,PICTURE_WIDTH, 0, 0, PICTURE_WIDTH, PICTURE_HEIGHT);
The point is I believe creating a Bitmap object is exacting and not necessary in this case. Is there any other faster way to convert rgb_565 array into argb array? I need this because making image processing on rgb_565 array seems to be a little annoying. Or maybe it is not so hard?
Android :: Converting Short Array To Byte Array
Feb 16, 2010I am trying to make an application that would be able to send the user's voice over the network using RTP. I am using the ported stack from hsc (JLIBRTP) and I am able to record user's voice in a saperate thread. the problem is that jlibrtp uses has a class named RTPSession that is responsible for the session and has the sendData method that takes a byte [] as argument and the AudioFormat class I am using to record user's voice is in AudioFormat.ENCODING_PCM_16BIT wich is short. I have tried using 8bit audioformat but I get an illigalargument exception in my htc magic and in my emulator. So is there any way I can convert the short [] to byte [] ? would that be acceptable in order of voice quality?, is the above error a known bug for htc magic or the platform doesn't support 8bit audio format?
View 3 Replies View RelatedAndroid :: Navigating An Array - String Array
Oct 12, 2010I'm new to android developing but right now I'm working on an application that displays Random Facts. Since I don't want it to be in a random order, I would like to have them in a list. I would like to order through them one by one and show them using TextView.
Resources res = getResources();
myString = res.getStringArray(R.array.FactsArray);
That's what I have so far. If I'm right, that just establishes the array so I can be able to use it later. What I had before was rgenerator which chose a random string from the array and displayed it when I clicked a button.
CODE:................
But Like I said, I would like to just order through them one by one when a button is clicked.

View 11 Replies View RelatedAndroid :: SharedPreferences Are Not Stored
Nov 21, 2010My problem is using SharedPreferences. I just created a <PreferenceScreen> which holds inside a <ListPreference> with an array of 5 different values. Very simple! The array of values are different numbers: 1, 2, 5, 10 and 30.Every time I change the setting, the application remembers that and I can see the setting I chose when I access the preferences once again (as an user). Now, in the code, when I retrieve the setting using the key (e.g. getString("delay", default_delay);), I always get the default value, it seems that the SharedPreferences does not find my setting. Can anybody help? I have read about SharedPreferences.getEditor().commit(), but that should be used only when changing settings from the code, not from the UI preferences.

View 8 Replies View RelatedAndroid :: SharedPreferences Bug When Writing Strings With Ampersands In Them
Mar 6, 2009I've just tracked down a weird bug in our app where SharedPreferences were failing between power cycles of the phone.
It turns out that one of the strings we were saving had an "&" in it. When I look at the xml that is being persisted I see that this is being encoded as && instead of just &
This means that when you come to read the settings back you don't get any values at all. Is this a known issue? I see lots of posts about preferences dissappearing, but nothing about this.

Android :: Can't Write SharedPreferences After Update / Sort It Out?
Sep 28, 2009I'm trying to prepare an update to one of my apps and I just realized that the updated version cannot read or write over the previous version's SharedPreferences.
Some details: * I'm using the 1.6 SDK and compiling for 1.5.3. * My androidmanifest.xml does not have a sharedUserId (I didn't think I need one if I was not sharing data between different apps).
How to reproduce: * Install my current app from the market * Run the app * Exit and save the setting - invoking SharedPreferences Editor commit (it's using MODE_PRIVATE) * Now install my new update (via a browser download) * Run the app * Everything works fine * Exit & Save *** Now reboot the phone * Run the app again ==> Can no longer access old data or write over it!!
Did I do something wrong? Is it because of the sharedUserId thing? Is it because of the way I'm testing - via market then browser? Why is LogCat reporting a UID change? ==> mismatched uid: 10031 on disk, 10046 in settings; Can I recover from this? I don't want to delete all of my users' data. error ...

Android : Can I Use Current SharedPreferences Tag To Store Values From PreferenceActivity?
Aug 5, 2010Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..

Is there an easy way to do this?
View 1 Replies View RelatedAndroid :: Updating Our Applicatoin On The Market Deletes The Saved SharedPreferences
Mar 9, 2009We have an online multiplayer game that saves some login information in the SharedPreferences. Our app is copy protected and everything was going really well until this weekend when we released an update for it. It seems that at least some of the people are having their SharedPreferences deleted when they updated too the new app. As you can imagine our users are furious because they're all loosing their profiles, and our ranking is dropping fast.
We've tried to reproduce this a hundreds ways but are unable. We're wondering if this could be related to installing a copy protected app over a copy protected app? Since that's the only situation we haven't tested and can't test.
