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 click install on the app brain website after activating fast web installer and nothing happens.

View 2 Replies View RelatedI had a bunch of code in an activity that displays a running graph of some external data. As the activity code was getting kind of cluttered, I decided to extract this code and create a GraphView class:
public class GraphView extends LinearLayout {
public GraphView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.graph_view, this, true);
}
public void start() {
// Perform initialization (bindings, timers, etc) here
}
public void stop() {
// Unbind, destroy timers, } }
Moving stuff into this new LinearLayout-derived class was simple. But there was some lifecycle management code associated with creating and destroying timers and event listeners used by this graph (I didn't want this thing polling in the background if the activity was paused, for example). Coming from a MS Windows background, I kind of expected to find overridable onCreate() and onDestroy() methods or something similar, but I haven't found anything of the sort in LinearLayout (or any of its inherited members). Having to leave all of this initialization code in the Activity, and then having to pass it into the view seemed like it defeated the original purpose of encapsulating all of this code into a reusable view. I ended up adding two additional public methods to my view: start() and stop(). I make these calls from the activity's onResume() and onPause() methods respectively. This seems to work, but it feels like I'm using duct tape here. Does anyone know how this is typically done?

Problem: I have one app that let's you lock the device using Device Administration. One of my users had some conflicts with my app and another. He then removed Device Administration and uninstalled my app, rebooted his phone, and now he cannot access his phone.
He of course cannot use my app to change the password now (since it's uninstalled).
His phone is stock 2.2 LG Optimus V, Virgin Mobile, Rooted.
Question:I'm needing to find a way that my user can now change his lock code.
I need:
1.) to know an internal class (from com.android.internal) that I could use within an app to change the lock code (just like the system settings do).
2.) to know a command I can use with adb shell to remove or change the phone lock code.
3.) to know the location of the file that stores the lock code information.
Some classes are NOT PUBLIC like android.os.ServiceManager, android.view.IWindowManager, etc, they are implemented in the mobile devices, but not present in the SDK .jar. This is because these classes are private APIs . now please tell me is there any way like compiling source code or importing private class file into android.jar so that i can use this private APIs.

The Android code on how ContentProviders work, and to me, it looks like any ContentProvider I query actually gets placed entirely in the memory of the requesting application. Are they really stored in the querying application's memory? For some reason I thought the cursors were lazy.

I just switched from Ubuntu 8.10 to Ubuntu 9.04 and noticed that Eclipse Content Assist isn't working anymore. I tried the following variations on Ubuntu 9.04: Eclipse 3.4.2 or 3.5 (cleaned / reinstalled) with ADT 0.93 and Android SDK 1.5r3 Using Sun Java 1.6. No combination works. I've reinstalled everything a bunch of times. I have another machine with Ubuntu 8.10 and Eclipse 3.4.2 with ADT 0.91 or 0.93 and Code Assist works for all those. I just refuse to develop without code-assist and I know lot of people would agree with me on that.

View 4 Replies View RelatedI'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.
