Android :: Cannot Resolve MapActivity Class
Sep 1, 2010
I have an application which has 11 different activities. One of these activities is an extension of MapActivity (it is a map for data visualization). To get to this activity the user must first travel through the launch activity, then 3 other activities.
The code to launch the MapActivity is:
CODE:..............
When this is executed I get the following output from the Log:
CODE:.......
I do have the target set to Google APIs, this is an app meant for Android 1.5, and specifies the minsdk to be level 3 in the manifest file. uses-library for maps is also in manifest file.
CODE:..........
I have been at this for almost 2 days now with no results. It seems that there are a lot of people having issues launching a MapActivity from other activities but there are no solutions anywhere.

I'm trying to use google maps on my android app but when i extend MapActivity instead of Activity in my activity file, there is an error that MapActivity cannot be resolved to a type...? I have <uses-permission android:name="android.permission.INTERNET"/> as a child of manifest and <uses-library android:name="com.google.android.maps" /> as a child of application too.....
Moreover, when i try to import com.google,android.maps.MapActivity, it says com.google cannot be resolved....

I'm just getting into Android development, and I have a question about communicating between a receiver class and an activity class. I'm very new to JAVA and Android so I hope I don't sound too stupid. I'm developing an application where I intercept an SMS message and then based on various elements of that SMS I might delete it once it's been saved to the inbox. I have a receiver class that intercepts the txt message, and I am also able to delete messages from my inbox with code in the activity class using a button at the moment. The problem I have is communicating between the receiver class and the activity class where the code to delete a message resides. I tried putting that code directly into the receiver class but as I'm sure most of you already know the BroadcastReceiver class doesn't seem to support what I need to delete messages. I've been searching for an answer to this for a while, but haven't been able to find anything. Honestly I'm not sure I know enough about JAVA and Android to even recognize a solution if I saw it.

What I want to do, is be able to access the object neoApi inside the Neoseeker class, from its inner class RunningTimer. Now, in my code, you can see what I would think to work, but when I run my application, nothing pops up. Nothing inside my TextView, no Toast, nothing at all. How can I remedy this?
package com.neoseeker.android.app;
import java.util.Timer;
import java.util.TimerTask;
import org.json.JSONObject;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;.......................

I'm new to Java and android development. In my application I need data which is accessible for a few activities. I've read that a good solution is to use Application class for this. So I use it like this:
public class MyApplication extends Application {
private String str;
public String getStr(){
return str;
}
public void setStr(String s){
str = s;
}
}
and I can access this variable from activity like this:........................................

I have a DROID using Android 2.2
I am attempting to get the simplest MapActivity to run on the device. (NetBeans latest and greatest using a Google Api build target.)
I have all the appropriate Manifest entries, the simplest OnCreate --- > all it does is setContextView() to the xml with a mapview in it.

I'm having problems getting a MapActivity to work on 1.5r2. As far as I can tell I've done everything I need to do, but what am I missing? The Google Maps key was generated on the Google Maps website using the Debug keystore at the location in my Android setup.
What does "Unable to resolve superclass of Lcom/bgies/truckerphonetest/DirectionActivity;" actually mean? As far as I can tell, the activity is setup properly.... At least it is setup exactly the same way I have other activities setup... with the exception that it's the only activity that has a mapView in it.
I can't run it either on my G1 or the emulator... so I assume it's something I am doing wrong. The project setup does have the Google APIs [Android 1.5], and the AVD for the emulator does show the target as Google APIs when I select it.
From my Android Manifest :

I have a problem with firing an activity that extends MapActivity. When it gets called, it throws a java.lang.NoClassDefFoundError... not sure what this is supposed to mean. I think something goes wrong with the external implementation of the maps API (maps.jar). Has anyone come across that problem? Here's the srack trace:

I want to add a MapActivity in an ActivtyGroup. As only single level inheritance is supported, my class can either extend from either MapActivity or ActivityGroup. As far as I know MapActivity is not a part of ActivityGroup. I want an activity to extend MapActivty as well be a part of an ActivityGroup.

I've got an app using MapActivity.onCreate() to initialize the map and show it on screen. Now I would like to add a menu to my app. From what I've found out I can't add a menu from MapActivity and need to use Activity (correct me if I'm wrong).
Now I have no idea how to "initialize" the map from my Activity-class.
And how would I have to fix the views, will I wrap my activity-layout around my Map-layout?

I have attached a mapview to my layout and have a it showing a compass and my current location, the problem I have is that there is no street map shown in the view, so basically I just see the compass and my current location over a blank grid.

Is it possible to use the terrainview in a MapActivity. The only way for now i could think to use the terrainview is using the browser- based version of Google Maps rather than using the native implementation, but that would not be my preferred way.

I have created a release keystore using the Eclipse IDE. I signed it using keytool and registered on Google Maps. I plugged in the key but my map doesn't show up. Maps show up properly when I use the key associated with my debug keystore. How can I diagnose this? I followed the same steps as i did with debug, for release.
UPDATE: Here is my manifest file:.................

I have a TabActivity that loads in 3 activity classes.In those Activity classes I have a button and an OnClickListener that tries to open a MapActivity class.I have searched to find an example of an Activity class launching a MapActivity class but cannot find one. If I swap out my MapActivity class with a Activity class it works.

Currently in my design I've got a base abstract class that all of my activities extend from, however I discovered recently that in order to use a MapView you need to make your activity extend MapActivity. Since Java does not have multiple inheritance I was wondering if there is any way I can use a MapView without having to recreate my design for my application.

An Activity that extends from MapActivity Uses ItemizedOverlay to show some balloons on the map ZoomControls are enabled
The ItemizeOverlay implements onTap(...) which works perfectly ok when tapping one of the overlay items.
The question is: How to identify a tap on another part of the map (with the intention of getting the location and center'ing on that point)

I'm building a small Android application, but this is more of a Java question than an android question. Looking through the tutorials there are lines that look like: startService(new Intent(this, MyService.class));
What exactly does the "MyService.class" field represent? Is that just a reference to the class for a template?
