I'm trying to override the onBackPressed() method of the ActivityGroup class:
public class MyClass extends ActivityGroup {
@Override
public void onBackPressed() {
// do something
return;
}
but I'm getting the error The method onBackPressed() of type MyClass must override a superclass method. I'm relatively new to Java, I've seen here that people do it and it works for them Why I'm getting this error? I'm writing an app for android 1.5, could the problem be here?
In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

I am using the showDialog and dismissDialog methods to show progress dialogs in my app. Moved from creating the dialog and calling show() on it to using this in order to save state when changing orientation.But when I change the orientation from portrait->landscape->portrait, the dismissDialog no longer dismisses the dialog. The dialog stay there all the time and I need to press the back button for it to disappear.

I can't seem to find a compatible ContentBody for .addPart.The problem I am trying to solve is that I already have the image in an ImageView within an Activity, so rather than read it again from the SD cara, I want to pass it to this method directly.I will probably scale it while I am at it.

View 2 Replies View RelatedI retrieve Json data (the JSONArray) and I wanted to make a List of all the names in the JSONArray, something like this.
List list = new ArrayList<String>();
for(int i=0;i < data.length();
i++){list.add(data.getJSONObject(i).getString("names").toString());}
And I wanted to take this list in an `ListView' so I did this:
ArrayList<String> test = history_share.list;
names_list = (String[]) test.toArray();
ArrayAdapter<String> adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, names_list);
setListAdapter(adapter);
History_share is one of the method I created to take json data from an api. Eclipse doesn't see any error, and me neither.
Basically I'm calling the onDraw method like so...

You see I'm drawing it on top of a Camera view and the information being drawn is subject to change. I have a listener setup which will update the variables being drawn at the appropriate time but I now want to "refresh" this draw in that listener.

I am using the showDialog and dismissDialog methods to show progress dialogs in my app. Moved from creating the dialog and calling show() on it to using this in order to save state when changing orientation. But when I change the orientation from portrait->landscape->portrait, the dismissDialog no longer dismisses the dialog. The dialog stay there all the time and I need to press the back button for it to disappear.
To overcome this issue, I tried adding a removeDialog in onDestroy so that the dialog is not created/displayed twice and before orientation change, the dialog is removed. Tried adding log statements and see what happens:

If we see here, initially when the activity is displayed, the onCreateDialog is called once and on changing the orientation, onSaveInstanceState and onDestroy are called. But after that, onCreateDialog is called twice (once by a call to showDialog which I make, but why the 2nd time?) and this happens every time I change the orientation hence forth.
I am writing automated test cases using Instrumentation. "waitforMonitorWithTimeout" always timesout. If I use waitForMonitor everything is fine. The two lines of code are below. (I comment out one of them when building my test project). Are there known issues with "waitforMonitorWithTimeout"? I have to use the timeout to determine if an event occured (and thus transition to a new activity) or not.

I am trying to write an app that will only run if the phone has a camera flash (i.e. not on my HTC Hero but on a HTC EVO 4G or Samsung Epic 4G, etc...). I found a code sample that will set the flash mode (and should work) but after modifying it to get the flash mode I am told that no phone has a flash when I run it even if they do. My code is as follows, I'd appreciate any help on figuring out what I did wrong since it looks correct to me.
