I have tried using MapActivity as it is suggested by this tutorial: http://developer.android.com/intl/fr/guide/tutorials/views/hello-mapv... However I get this error message in Eclipse: "MapActivity cannot be resolved to a type". Yes, I have checked Google APIs 4 and even verified that in default.properties. Code...

I'm trying to make a notification in Android.
But i get the error in the title by using:

Do i need to define something before i try to draw it?
I'm relatively new to Java, eclipse and android so this could be a completely silly question, but I'm going to ask it none the less.
I've got a project I'm learning with to test connecting to the flickr api and simply displaying recent images. I'm at the point now where I want to parse the JSON received from flickr. I've downloaded gson 1.4 and added the zip to the java build path through "add external jars." It's successfully loaded and I can see google-gson under referenced libraries in the package explorer. My problem is, when I try to use it, I simply get an error.
Gson gson = new Gson();
It highlights Gson and says that "Gson cannot be resolved to a type." What am I missing here? It worked once and has since stopped. I've tried removing the jars, cleaning the project and re-adding the jars but it still doesn't work.
I wish to have a single class which all of my Activity classes extend. I have ListActivities, Activities, MapActivities, TabActivities, etc in my App.
I have many of these different activities in my app, ~12 activities. I want each of them to have the methods which are in the parent class.
Right now, i have created 4 parent activity classes which are extended from a certain activity depending on their type(ListActivity, Activity, MapActivity, TabActivity)
I am creating a lot of redundant code - each of the 4 parent activities has almost identical code, in exception for what class activity it extends.
Here is an example that may clarify what my problem is:
I have an Activity: MenuScreen which extends BaseListActivity BaseListActivity extends ListActivity BaseListActivity contains methods and fields which i want all my activities to have access to I have another Activity: HomeScreen which extends BaseActivity BaseActivity extends Activity BaseActivity contains the same methods and fields which are in my other Base[<type>]Activity classes(such as BaseListActivity)
These methods/fields are copy-pasted to all my Base[<type>]Activity, and seems awfully redundant to me.
Can i create a master activity class which all types of Activity classes can use as its parent? if not, am i stuck with copy and pasting this code and feeling gross/dirty about it?
I have a use case in my application, where after certain point, I need to associate an data with an activity. So whenever an intent with an action and the data type is fired, my activity can be opened. I know that it is possible to associate a data type with an activity statically via AndroidManifest.xml.
Is it possible to register the data type for an activity dynamically and programatically?
Should I create a Listener within a BaseAdapter or should I pass it in? I have 4 classes that inherit from a base class. I pass the Adapter a list objects.
The Adapter is eventually used with a ListActivity I want to create a View based on the derived class and I want them to launch an Activity based on the type of a View. Currently I create the intent and Listener in the BaseAdapter. Is what I'm doing a good pratice?
I have used ImageView's before and understand the different scale types that can be set... However I am having an incredibly difficult time trying to get an ImageView to scale properly in the row of a ListActivity or an ExpandableListActivity.
I have tried setting the android:scaleType property to every single value but the image never scales down. I have set the min and max sizes as well and they don't seem to have any effect. I have done both of these things in both the XMl and in code to no avail...
Does anyone have any ideas or perhaps a workaround? code...
I have an application, which (for the sake of simplicity) has two types of activities - Overview and DetailView. The Overview activity shows a list of steps and allows the user to start a DetailView activity corresponding to the step chosen.
In the DetailView activity, the user can start another Overview, which shows different steps than the ones in the parent of the current DetailView.
In the Overview, DetailView is started by using startActivityForResult (). In the DetailView, when the user decides to start a second Overview, I call setResult () and finish () and then start the new Overview. In this scenario, onActivityResult () and finishFromChild () do not fire. Instead, they fire when the parent finishes (?).
Code from Overview:

Code from DetailView:

View 6 Replies View RelatedI updated to 1.5 SDK pre, together with the ADT. I followed the instruction to select Android 1.5 as target by right clicking on the project, Preferences>Android. In this window there are 3 options, Android 1.1 Android 1.5 Google APIs
I selected Android 1.5 and Apply, clicked OK. Application compiled nicely.
If I go back to the same Preferences and select Android 1.1, Apply, I can no longer compile my application successfully. I get hundreds of the same error R cannot be resolved

Everything was working fine earlier. I then happened to add a new xml file to my layouts. now, one of my classes is giving an error when setContentView points to (R.layout.menu).

View 1 Replies View RelatedMy current situation is that I have a phone with 2 camera apps on it, stock and camera FV-5.
Camera FV-5 is slower than the stock camera, so I only use it in situations which I need manual control.
Whenever I open whatsapp and try to send a photo, the app asks me which camera I want to use, with no option to always use stock. I don't want camera FV-5 to exist as an option, as I will open it if I want to use it.
Is there a way to remove an app from the list so that my phone does not recognise camera FV-5 as a camera?

I've been following the View tutorials included in the android developer site. When testing hte HelloGallery view, I get this compile- time error.
I searched for this error on this group but is wasn't answered. Can anyone help.
The problem reference occurs in the imageAdapter class that is appended after the onCreate() method in the HelloGallery class:
CODE:...................
Strangely enough, when I insert this lines into the onCreate() method at the start of the package, there is no problem. It seems that the android.R class is not known.
When working on the Hello, Gallery tutorial/sample app, after following the instructions on the site, Eclipse reported that R.styleable cannot be resolved. What is the reason for this error, and how can it be fixed or worked around?

I want to be able to show the Battery Info activity in my app, which shows things such as the exact level, battery health, etc.I'm not sure how I can get it, though a few applications such as Power Manager, Any Cut, etc. show this screen as well. I found in the source code of Settings this intent in a file called testing_settings.xml,But I don't know how to use it. I would guess from the fact that Any Cut has a list of activities, that a list of said activities exists somewhere, and therefore an easy way to access them exists, but I haven't found it.

View 1 Replies View RelatedSo I have an app with Activity A. The layout on the activity is dynamic genearted. So it's possible that on Activity A a user hits a button that goes to "A" and the new page looks different, then a user clicks another button to go to "A" again. Now I have 2 Activities in the history stack. A, A, and currently on A. Is it possible that if a user clicks a button that the whole Activity stack is cleared in a scenario such as this?
