Android :: Why Does LocationListener Become Null?
Jan 28, 2010I am having issues regarding a LocationListener in my Service called myService.
Here is my code:
///onStart method ..
onStart() {
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE)
.
.
provider = locationManager.getBestProvider(criteria, true);
locationListener = (LocationListener) new MyLocationListener();
locationManager.requestLocationUpdates(provider, 0, 0, locationListener);
}
In my Activity there is a button which should stop the service. On the click of the button I am doing:
stopService(new Intent(getApplicationContext(), myService.class).................
Android :: Use Null Layout ?
Mar 8, 2010Is there an equivalent to Java's null layout in Android? Basically I want to specify the x and y coordinates of each component and not have the layout manager choose where they go. They will be within a scroll pane so it doesn't matter whether they fit on the screen.
I know null layouts are generally not a good idea but I have a special case where I need it. I'm porting a Java TV guide app and the program grid is made up of JLabels. The program dynamically generates them all, setting the x and y coords based on start/end time and channel. Each program could start and end at any time so as far as I know a table layout won't work.

Android :: Geocoder API - Returns A Null Value
Aug 26, 2009I am having a real hard time with the geocoder API of android sdk 1.5rc2. In my app I am trying to get the addresses corresponding to a location name by using the getFromLocationName method of the Geocoder class. But the problem is whenever I call this method it returns a null value. I have also pushed a geodb file containing some fake addresses at 'data/misc/location' directory in the phone.
The format of the data in the geodb file is as follows :
address 1 latitude "38.898763" longitude "-77.036655" line 0 "1600 Pennsylvania Ave NW" line 1 "Washington, DC 20006" locality "Washington" region "DC" postalCode "20006" countryCode "US" countryName "United States"
and following is the code snippet : Geocoder geocoder = new Geocoder(this, Locale.getDefault()); List<Address> addresses=geocoder.getFromLocationName("1600 Pennsylvania", 10);

Android :: ANDROID_ID Returns Null On G1?

String ID = Settings.Secure.getString(context.getContentResolver(), android.provider.Settings.Secure.ANDROID_ID);
but this returns null when running on my G1. Is it supposed to be returning a valid number, or am I accessing it wrong? I don't want to use the telephony device ID because that requires more permissions.

Android :: GetRingtone Returns Null
Feb 1, 2009why RingtoneManager.getRingtone(this, Settings.System.DEFAULT_RINGTONE_URI); always returns null when launching from my activity? Shouldn't it return some object which is System.DEFAULT_RINGTONE_URI, which I can then play()? Is there any small example of code which shows how to play Ringtone from Activity? MediaPlayer way also not works. MediaPlayer.create(this, Settings.System.DEFAULT_RINGTONE_URI)
simply crashes with:

First Android App And Null Bundle Object
Oct 29, 2012I've gone through the Notepad Tutorials and they are all working on my virtual device. I am now stuck in the midst of trying to write my own Android app.
My setup:
Windows 7 SP 1 64-bit
Eclipse Indigo Service Release 2
Android Development Tools 16.0.1.v201112150204-238534
Android Virtual Device Platform 2.3.3, API Level 10, CPU/ABI ARM (armeabi)
The app is about as simple as they come - you enter a number, it divides it by another number and displays the result.Here is the code involved:
AndroidManifest.xml:
Code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.android.driving"
android:versionCode="1"
android:versionName="1.0" >
[code]...
By the time DrivingTimeEstimator's onCreate() method gets executed, the Bundle object (savedInstanceState) is null (which I'm guessing is what leads to mMiles being null, which throws a NullPointerException and kills everything).

Android :: Way To Know Another Thread's Handler Not Null Before Calling It?
Feb 2, 2010My program threw a NullPointerException the other day when it tried to use a Handler created on another thread to send that thread a message. The Handler created by the other thread was not yet created, or not yet visible to the calling thread, despite the calling thread having already called start on the other thread. This only happens very rarely. Almost every test run does not get the exception. I was wondering what the best way is to avoid this problem for sure with minimal complication and performance penalty. The program is a game and very performance sensitive, especially once it is running. Therefore I try to avoid using synchronization after setup, for example, and would prefer to avoid spinning on a variable at any time.

View 1 Replies View RelatedAndroid :: BitmapFactory.decodeStream Returns Null
Oct 3, 2009I have an activity which performs an image search, the results (URLs of thumbnails on the web) are rendered in a GridView. My GridView adapter class delegates creating the actual Bitmaps to an AsyncTask that loops to sequentially fetch the image content from each URL using HTTPClient, and creates the Bitmaps using:
BitmapFactory.decodeStream(entity.getContent()).
I found that the above method sometimes returns "null" silently instead of creating a Bitmap. The occurrences appear to correlate with larger stream sizes (I check this by logging entity.getContentLength()). However, if I put a breakpoint just prior to the decodeStream call & then resume immediately every time I hit it (i.e. pause briefly on each iteration), the Bitmaps are created perfectly every time. All the images are quite small (most <10K), so the download & decodeStream happens fairly quickly. There are never more than 10 images processed in one AsyncTask.

Android :: CacheManager.getCacheFileBaseDir() Always Returns Null
Mar 15, 2010I've been trying to use the CacheManager for caching some http requests but it failed every time with a nullpointer exception. After some digging I believe I found out why: CacheManager.getCacheFileBaseDir() always returns null so when I try to use CacheManager.getCacheFile() or CacheManager.saveCacheFile() they fail.
CacheManager.cacheDisabled() returns false :S I hadn 't created a cache partition via the AVD manager so I thought the problem lie there. But after creating a cache partition getCacheFile() still return null:
03-16 00:25:16.321: ERROR/AndroidRuntime(296): Caused by: java.lang.NullPointerException 03-16 00:25:16.321: ERROR/AndroidRuntime(296): at android.webkit.CacheManager.getCacheFile(CacheManager.java:296)
What could be the problem? I've got the code posted here: http://pastebin.com/eaJwfXEK But it's a bit messy because I've been trying tons of stuff.
