Android :: Custom MapView Throwing NoSuchMethodException?

Sep 10, 2010

I'm trying to implement a custom MapView. Inside my MapActivity (named mainmap) I have an inner class which extends MapView:

CODE:........

I have my main.xml formatted to find the inner class like so:

CODE:................

Also, in Androidmanifest.xml, I have the appropriate <uses-library android:name="com.google.android.maps"/> entry.

When I try to run my app, I get (amongst other things) in logcat:

CODE:..............

This is caused by this entry I find in logcat:

CODE:...............

If I understand correctly, my app is crashing because Android is saying it doesn't find the appropriate constructor for my custom MapView (the Lmapview class). As you can see above, however, it is defined and it matches the signature it is looking for.

Android :: How To Attach Custom Map On MapView?

Jul 9, 2010

I am trying to place my custom map (overlay) over Google map. For example, my MapView will be positioned to look at some building. I want to load custom image(s) that will show building's floor plan. Want to be able to pan and zoom, and place markers (for example, Room 1, Room 2, etc...), in other words, I would like to be able to use Google Map API methods. The best would be if Google map images are not loaded at all, since that will (I believe) slow down user's experience. Also, the user may be inside the building, and connection may be slow or non-existing.

Android :: SQLite Query Throwing Exception

Jul 29, 2010

Im trying to get an object form my SQLite database in my Android application. I know that the contact is in the database because when I add it and try finding by ID, it returns the object. When I try finding by first and last name, though, it throws an exception and Im left with a null reference.

Here is the query:

CODE:..........

Ive also tried to find just by first name and just by last name. Same result as above.

The exception is an SQLite exception

no such column: aurelius: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus AND last_name=aurelius

And also happens when trying to select just first or last name

no such column: marcus: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus

Android :: FindViewById In A Subclassed SurfaceView Throwing RuntimeException

Oct 9, 2010

This code works fine if I move the findViewById call in to the Activity. Any hints as to why it doesn't work from inside the LearningView class? I've tried moving the TextView inside the com.example.LearningView tag but no joy. I'd prefer to get the TextView from within the SurfaceView subclass as I feel it's more logical to treat the TV as a "child" of the SV.

This is a contrived example I wrote to figure out the problem in a larger application, but the gist of it is the same, and the stack trace is basically the same.

For what it is worth, the findViewById call is returning null, which obviously threw NullPointerExceptions in some attempts to fix this.

As you can probably gather from my attempts I'm flying blind on this one.

Learning.java:

CODE:..........

main.xml:

CODE:..............

Android :: GL DEBUG_CHECK_GL_ERROR Throwing UnsupportedOperationExceptions For Things That Work

Sep 12, 2009

I turned on DEBUG_CHECK_GL_ERROR for my GLSurfaceView to try to figure out why I'm having a problem on pause/ resume/reload everything, and when I turned it on, I got an UnsupportedOperationException when calling GL11.glGenBuffers() (for creating Vertex Buffer Objects).

Why is it saying that operation is unsupported when:

1) The vertex_buffer_object extension is listed on the target device and my code checks for it before trying to use VBOs.

2) VBOs are working correctly (and really well might I add).

This is on a G1. Yes, I know the G1 is only OpenGL ES 1.0 compliant and I'm trying to use a 1.1 extension, but if the phone lists the extension, doesn't that mean I can use it? Also - the extension works! Does this mean that it works but use-at-your-own-risk, kinda like how SoundPool was in Android 1.0?

Android :: TextView With URL Throwing Exception When Finish() Called In OnResume()

Apr 6, 2010

I created a TextView and put an url to it, using setText(Html.fromHtml("");. Its opening the web page in the built-in browser and when I press back, its coming back to the application.

I don't want to come back to the application, so in activity's onResume(), I call finish(). Its exiting at the first time. But when I open the application again, its throwing some exception.

Any other way to close the application, other than this way.

Android :: Java Socket Not Throwing Exceptions On Dead Socket?

Jun 29, 2010

We have a simple client server architecture between our mobile device and our server both written in Java. An extremely simple ServerSocket and Socket implementation. However one problem is that when the client terminates abruptly (without closing the socket properly) the server does not know that it is disconnected. Furthermore, the server can continue to write to this socket without getting any exceptions. Why? According to documentation Java sockets should throw exceptions if you try to write to a socket that is not reachable on the other end!

Android :: MapView Overlays

Sep 28, 2009

My problem is my MapView becoming very laggy and so non-responsive at times, that Android thinks its hit deadlock and tries to close it.

I am adding 60 overlays to the map view and i originally thought that the icon size may be causing the problem by using up all the memory. When i decreased the overlay icon size, it did improve things, though it is still to slow to be usable. Has anyone experienced anything similar and have a workaround? There may be a better way of doing it other then extending the Hello MapView example.

Android :: Add Overlay To MapView?

Sep 28, 2010

I have subclassed Overlay as LandMarkOverlay (and implemented an onTap(GeoPoint) method).

In the main activity I do this:

setContentView(R.layout.main);

MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
landmarkOverlay = new LandmarkOverlay();

//add the landmarkOverlay to the list
mapView.getOverlays().add(landmarkOverlay);

What else do I need to do so that when the user taps the screen, landmarkOverlay's onTap(GeoPoint) method gets called?

Android :: MapView Draw Overlays

Feb 14, 2010

i have a problem with my mapView. my app reads "some" gps points out of a file and i want to draw a route (drawing lines between the gps point). If my file contains many gps points, my app works really slow. i think its working slow, because i draw all overlays. now i want to check, whether a point is visible in my mapView or not. so i have to get the mapCenter and Lat/lon span (getLatitudeSpan,..) !? how and where must i save my points and how can i check all my points (after my mapCenter has changed for example). Shall I save my points in a list (in my Overlay class??) and iterate through every list item and check, wheter its visible or not?

Android :: Dynamic Pin Overlays In MapView

Oct 29, 2009

I've been reading the (shoddy) documentation for the Google Maps API (MapActivity et al), and I think I have roughly worked out how it works. It seems that if you want to add a marker overlay you can use ItemizedOverlay easily, but you have to add all your markers at once. There doesn't seem to be any way to remove them.

What I want to do is query markers from an online database as the user pans around (in the same way the actual map tiles are fetched). Is there a simple way to do this?

As far as I can tell I need to subclass Overlay and implement the draw method, but where is the best place to put the code that fetches new markers when the map is panned? There doesn't seem to be an onMapChanged() method anywhere. My best guess is MapController.onKey() but that seems wrong.
