Does it mean I need to extend both SQLLiteOpenHelper and Activity?

I'm guessing it has a problem with "this." I'm still learning about Android so I'm going pretty basic.
I am getting the following error:

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 RelatedIm 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.

I have two classes, one MainClass and one DataBaseHelper class, which extends SQLiteOpenHelper.
From my MainClass I call a method in the DataBaseHelper class to open a data base. Before opening the data base I want to check the users data base version (this is important as soon as I want to update the data base and push it to the Android market). So from the DataBaseHelper class I call the following method, which is in the MainClass.

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 one other error shown in the linked image below, but I don't see why.
Here is the linked image.
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.

I've created a test project with three identical classes that extend BroadcastReceiver, named
TestReceiverOne TestReceiverTwo TestReceiverThree
They each have the following function as their content:
CODE:...................
I've added each BroadcastReceiver class to the manifest, have it accept the appropriate action/category, and start debugging. I've set breakpoints in the onReceive method of each test class, and in the anonymous inner BroadcastReceiver in my onCreate.
Unfortunately, I seem to be getting somewhat undefined behavior. Sometimes getResultExtras in my second onReceive will return null. Sometimes getResultCode in the second onReceive returns 0. Sometimes I'm 1 off in my third onReceive. Sometimes I get the wrong numResults in onReceive in my activity.
Is there some other behavior I have to specify when using setResult and getResult in an ordered broadcast?

View 3 Replies View RelatedDoes anyone have any idea how to find the n-th field (string) in a delimited string where the delimiters (separator) could be either a single char or several chars.and the syntax for user-defined function is FindNthField(string,separator,position)so position 3 would return three,The separator in use would actually be Chr(13).This has to run on Android and so should be efficient.
