I'm looking to test some code I've written and to do so I need to construct a variable of type Location and to give it a long / lat value but I'm unsure how I would do so.

I have tried to understand for the past 2 days what is the best approach to making the value from a variable sitting in activity A (in my case, the int position used in OnListItemClick / OnItemSelectedListener) available in another activity B (which of course sits in another class). There may be the option to write the result of the OnListItemClick int position into a small SQLite DB - but that seems to be total overkill.
Anybody could pls share the best approach with me?
I am trying to run a simple program which shows lat and long values but Location value is always null.

I am trying to create an Android maps project. Everything was working fine until i added Salesforce classes into it. Now it doesn't even compile. It gives me: Type Conversion to Dalvik format failed: Unable to execute dex: null error.
I tried 1) Increasing memory in the .ini file. That didn't help. 2) Project -> Clean option. It cleans, builds again and then gives me the same error.

I'm trying to get a location from lat /lon values with the getFromLocation function:
adresses = geocoder.getFromLocation(lat, lon, 1); // Search addresses
The function should return a empty List, if it don't find an address, but it throws the NullPointerException. What can/must I do to fix it?
I have an activity that implements LocationListener in my application and my onLocationChanged method has been working perfectly up until recently. For some reason the Location object being passed into the method is null. My question is, why is it null? Does it pass in a null object if it cannot acquire a location?
My GPS is on and I have it set to pull a location from the GPS, and I know my GPS can get a fix on me as I used Maps and had it locate me.
Also, I have the permission for my app set as:

I don't believe permissions is the issue though, as my activity was working beforehand and I have not altered the permissions since then.
Here is the code that determines the provider of the location object:

Here is the LogCat output of the error:

I have tested the same code on another device (an HTC MyTouch 3G to be precise) and it works flawlessly with the GPS, however on my Motorola Droid it crashes.
I've been looking through the filesystem of android, and for the life of me cannot find the files that make up the settings menu in android. It's been a long while since I've attempted modifying anything myself.
View 2 Replies View RelatedIs copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

I have two questions about wallpapers on my nexus one. First off, is there anyway to take a custom image that I have and I am using and put it into the list of "default" backgrounds so that when I change it I don't have to go through that resize hassle and everything and I can have it in a more organized location. Also are there any applications or tools out there to get great looking wallpapers for the nexus one. Sometimes when using an image it doesn't look that good and the selection thing when doing it from the gallery is annoying because of the selection has to be a square yet my screen is 800x480.
View 2 Replies View RelatedI am building a camera app, where photos and videos are continuously being captured and saved to the SD card. The videos are short (few minutes), and their length are preset with setMaxDuration(). When Media Recorder.MEDIA_RECORDER_INFO_MAX_DURATION_REACHED is reached, the video is saved, and a new sequence is initialized with something like: The whole process works fine, while the main activity is in the foreground. But, when I go to another activity (e.g. settings), the video recording works in the background only until max duration is reached. The file is saved, but a new sequence can not be started because prepare() fails. setPreviewDisplay() needs to be there, but it doesn't like not having a proper surface to attach to. I tried to use a dummy Surface, a dummy SurfaceHolder, or reuse the Camera with mMediaRecorder.set Camera(), but nothing works. Is there a way to initialize Media Recorder in the background?

View 3 Replies View RelatedI've been having an issue with using AudioRecord for Android. I've read as much as I can find online about it, but I cannot seem to get a good initialization. I have tried the Android 2.2 emulator, 1.5 emulator and my phone, an HTC Incredible running Froyo. The emulators and my phone fail initialization. I've tried sampling rates of 8000, 11025, and 44100, formats of CHANNEL_IN_MONO/STEREO and CHANNEL_CONFIGURATION_MONO/STEREO, 8bit and 16bit encoding (8 bit makes the getMinBufferSize fail), and Audio Source of MIC and DEFAULT. All result in the variable test becoming 0 after running a get state(failed initialization). It seems from everything I've read that this should correctly initialize the object. I have played around with the multiplier on buflen, to have it range from 512 (the result of the function) to 102400 because I had heard that HTC devices require something above 8192. For testing my problem I made a new, small project that recreates my problem as simply as possible. I pull out the constants needed into local ints then run the constructor and access the getState method for checking if it worked. Code...

View 3 Replies View RelatedI'm adding Android C2DM to a Android library project. I started with the com.google.android.c2dm package that is included with JumpNote and Chrome To Phone. In order to use this package, you have to subclass the C2DMBaseReceiver service which takes the Sender Id as an argument to it's constructor. In JumpNote, this argument is initialized using a hard-coded static variable in a config class. However, in an Android library project, which may be used by multiple concurrently running apps I don't think I can use a hard-coded static variable (that is, I believe it could lead to problems when/if multiple apps are trying to access/modify the static variable). I tried to think of a way to initialize the Sender Id without using a static variable and am stumped so far.The obvious solution would be to use the Manifest or a Resource string or a combination of the 2. For example, in strings.xml I might have a "ac2dmSender" string, which is accessed in a meta-data child of the C2DMReceiver service declaration in the manifest. However, it seems that you cannot get a reference to the PackageManager or ResourceManager from a static context, so there is no way for me to then retrieve the meta data in such a way as to pass it in to the constructor of C2DMBaseReceiver.

Or is my Desire faulty?Hi, had my Desire about a week now and absolutely loving it.I bought a couple of spare USB cables from eBay (they were listed as being suitable for the Desire fwiw) - mainly for charging - but why I plug the Desire into my laptop with them I get Device not Recognized - even before I've selected the connectivity option on the Desire.It works OK with the HTC cable and a cable that came with my Jabra headset. The eBay cables seem to recognise an old Nokia 6300. So, as suggested in this thread, are all cables not created equal and the eBay cables of insufficient quality for the Desire or is the Desire faulty?
