I've written an Android app wich various abstract classes that perform useful functions. These functions could be leveraged in other apps. I want to share a class module with another programmer, but I don't want to share the source code. I would like to share a .class file but I'm not sure how to do the following:
Compile an Android .java file into .class What does the receiver of the .class file have to do to use that .class in their project? (using Eclipse environment)

Currently it seems to use the same package name as the one in manfifest defination of AndroidManifest.xml <manifest xmlns:android="http://schemas.android.com/apk/res/android"package="com.tejasoft.dialer.mobile.android"> Also, is there a way to give custom class name instead of default R name say Resources.

View 2 Replies View RelatedI have developed an application which has several packages within it's project. A class in one of those packages is called right away in the first line of code, which throws the dreaded java.lang.NoClassDefFoundError error. I don't get it, the package simply is within the project, and it works fine on my Android 1.6 device, but won't work with my 1.5 device. I do have to say that the project was originally set for 1.6, but then I changed the within the manifest from 4 to 3. Is that bad practice? Or maybe it has nothing to do with the platform version? Also I do get these lines as wel from the DDMS :

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.

str = s;

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?

In Android, if I want to do some background work, what is the difference between
Creating a Service to do the work, and having the Activity start the Service VS. Creating a standard java class to do the work, and having the Activity create an object of the class and invoke methods, to do the work in separate thread.

Class AddText(extends Activity), Grafitti(extends MapActivity) and MarkerOverlay. Grafitti calls AddText, and AddText opens a new Activity that gets an input from user (EditText), then when that is successful Grafitti calls MarkerOverlay. The problem is I can't access the input in AddText. I need to use that input in MarkerOverlay, I tried creating a setter and getter but it won't work. (error) I've tried searching the web and I think the solution is Bundle. I'm having a hard time understanding how Bundle works. Is there any other way? or any code snippet on how to use Bundle. A code snippet would really help me a lot.
