Aug 8, 2010I am using the following method in a new application I'm developing. There is a main activity, which instantiates different classes that extends RelativeLayout and I'm using setContentView to switch between the different modules of the application.

View 1 Replies View RelatedAndroid :: Communicating Between Receiver Class And An Activity Class
Jul 14, 2010I'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.

Android :: IntentNotFoundException For TextToSpeech.Engine
May 7, 2010I am trying to implement text to speech by following this article on the Android Developers Blog. It suggests the following code for installing text to speech data if it is not supported.
CODE:...........
This throws an Exception:
ActivityNotFoundException: No activity found to handle Intent
However, I am using the code here to determine the the intent is actually supported. Here is the list representation:

Android :: Starting An Activity From Callback Class
Aug 18, 2010I have an activity class(Application Class ) which calls a service class(Service Class) and closes. The service class takes about 5 seconds to complete its task and calls a method which is present in another class(Callback Class). Now according to the result, the callback needs to notify the Application class.Once i get the callback from the service, I tried calling a method defined in the Application class. In this method i create a new intent of Application class and call startActivity(Application Class). But this is not working. Can anyone tell where i am going wrong and what can I do to solve this issue.

Jul 28, 2010I've got two activities, one of them is called MyActivity. I want both of them to be able to use a function located in a class othat we may call MyClass. In MyClass, I try to use an intent to launch the activity AnotherActivity. Since the constructor takes a context as parameter, I simply tried to store a context from the activity in the constructor, and then use it when I try to create my intent.However, even thought none of the arguments are null (checked that with a simple if-statement), intent seems to be null and a NullPointerException is thrown. Why does it not work, and what can I do to solve the problem?
I'm quite new to Android and Java development, so please explain it as basic as you can.
Android :: Static Database Class To Use With Any Activity
Jan 5, 2010I am new to Android, and I haven't developed any app regarding databases on Android yet. So I have a few basic questions. I am after a good database class sample, that will let me to run the CRUD operations. I would like to use it as a static class
like: clsDB->Select("select * from clients");
or objClient->Delete(clientid);
I am wondering if someone, can share his database classes, if more people share the best. Also I have in mind to reuse this class in multiple ways, I will have services, activities etc...
Android :: Starting An Activity From A Random Class
Sep 18, 2010I've adapted the GridInputProcessor-class of the 3D-Gallery ( http://android.git.kernel.org/?p=platform/packages/apps/Gallery3D.git;a=blob;f=src/com/cooliris/media/GridInputProcessor.java;h=91dfd4783be6b21ec8ff2518a5c244752570e90d;hb=HEAD ) so that it detects upward/downward swipes.
The detection of swipes works, but I now want to start another activity (or draw a bitmap on the currently displayed activity), but I seemingly can't use startActivity(mContext, myIntent), because the class declaration is public final class GridInputProcessor implements GestureDetector.OnGestureListener, GestureDetector.OnDoubleTapListener {so it doesn't extend Activity...
Can I still start an Activity through this class, or how would I go about doing this? I have also tried sending a broadcast, but this is also not "implemented".

May 4, 2010For example, I have an activity that uses a utility class. I would like to be able to start an activity from the utility class and have the activity result sent back to the utility class.
The only way I could think of starting the activity was to pass the original activity to the utility class, so that the utility class could use the original activity to start the activity. The problem with this is that the activity is sent to the original activity, rather than the utility class.
I also thought of actually making the utility class an activity itself, but that would make using the utility class much more complicated.
