I am developing an app that upon receiving an SMS message with a unique string of text, the GPS is enabled and starts tracking the location of the phone. The issue I'm having is with the getSystemService() method.
I receive the error "The method getSystemService(String) is undefined for the type SmsReceiver", I believe this is because it does not have a context. I have tried to add in a context with in my code with 'ctx', and that removes the error but my application crashes every time I run it on my phone. The code for recieving the SMS works fine, and the GPS location tracking code works fine if it's in my main class.
I still don't fully understand contexts.

View 1 Replies View Relatedmy app is working perfectly and playing its music in the 1.5 and 1.6 emulators, my ADP1, and for everyone in the Android Market (at least there were no complaints). The problem is that when the app is run on the ARCHOS 5 tabled, the MediaPlayer.create(Context context, int resid) method returns null. I guess there might be a problem with the ARCHOS' Android implementation, but did anyone experience the same problem? What might be a possible reason for the create method to return false? The docs don't say anything. I'm also using SoundPool in parallel with MediaPlayer if that's relevant.
View 2 Replies View RelatedI'm working with Android 2.1 and have the following problem:
Using the method View.getDrawingCache() always returns null. getDrawingCache() should return a Bitmap, which is the presentation of View's content.
Example code:
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final View view = findViewById(R.id.ImageView01);
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
final Bitmap bmp = view.getDrawingCache();
System.out.println(bmp);
}
I've already tried different ways to configure the View object for generating the drawing cache (e.g. View.setWillNotDraw(boolean) and View.setWillNotCacheDrawing(boolean)), but nothing works. What is the right way, or what I'm doing wrong? In real code I want to apply getDrawingCache() on a ViewGroup like RelativeLayout. Is the behaviour the same when using a ViewGroup?
I am doing some android application. I just wonder what will case the managedQuery method return a null value?
I've seen topics discussing this but no one has seemed to post a solution. At the moment, I'm testing passing parameters to my .Net web service. When the parameters reach the web service it adds it with an additional string then returns it too my application; but all I'm returning is the string message, not the parameter I passed. Is there something wrong with my web service or my soap method?

Im trying to make an activity that has a multiple choice dialog after you push a button. In there you select from a list of things. But these things are received from a web method before the dialog appears. So I create a string array after I receive them inside the onCreate to initialise it there with the correct size. But my dialog method then cant get the array because propably its out of its scope.
My code looks like this:
CODE:............
I cant initialise my array when the class starts because I dont know its size yet. This has to do something with the scopes of my variables and I am pretty confused
When programming for Android sometimes you have to use static methods. But when you try to acces you resources in a static method with getString(R.string.text) you'll get an error. Making it static doesn't works. Does anyone knows a good way around this because the resource files in Android are very helpfull for creating things in different languages or making changes to a text.
View 2 Replies View RelatedI have code which has one activity which passes information to a second activity.
I can use this information to pass to a third activity with additional information from the result of the second activity.
I want to use gestures as a method of going back to a previous activity, but if I go back from the third to the second activity I need the information initially passed from the first to the second activity to still be present.
i.e.
First Acticity
what is Y?
answer y = 5
Second activity
User said Y = 5
what is X?
Third Activity
User said Y = 5
X = 6
Go back to Second activity but maintain the input of
User said Y = 5.
To do this I have used a bundle to pass the information between activities, but I can only access the info in the bundle from within a method within the class started by the intent.
The gesture controls are within another class, so I cannot access the bundle information from within this class as the getIntent command produces a not defined error.
What I need to do is to be able to pass the information from the bundle from the first activity to the gesture class so that I can pass it back when I go back using the gestures.
If the value of imageFileName is null, why can I not change null into a string? It was working before 1.5. String imageFileName = myFile.imageFileName.toString(); This gives me the a NullPointerException Error.

I have created a program, with a service - the service is "START_STICKY". So when i close the program (i am using Advanced Task Killer, to kill programs) the service is restarted automatically, but this presents a problem cause i get an error when trying to call ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203) (see stacktrace below).
I have created a class to handle context, which will return my Activity's context if it is not null, or a fake one i created if the activity's context is null - and the activity's context is null so the fake one is used, i suspect this may be the problem, but have no idea.
In my activity i have a constructor which gives a reference of it self to the contexthandling class, but it seems the activity is not instantiated (not before the service is started at least) when the system is restarting my service.
There is of cause no problem when the program is just started normally, the service starts fine then... which is why i am suspecting the fake context, i created it as follows (and it is referenced in the manifest application tag with android:name=FakeContext):

I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.
View 4 Replies View RelatedIn Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

View 5 Replies View RelatedI started learning Java and how to program for Android last night. So far I'm on this tutorial: developer.android.com/resources/tutorials/views/hello-tabwidget.html. Clearly these tutorials have been designed for people that already have experience with Java.
Despite the tutorial lacking all the required steps (for an absolute beginner with Java) and even having a typo, it seems I've figured everything out (which I'm really proud of :p). Except I cannot figure out how to fix TabHost tabHost = getTabHost(); which apparently is undefined.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
Can anybody give me some clue that how to convert binary string into a string(english). I have tried and googled so much but couldn't find an answer.
