The automatic generation of the R class does not work anymore. I have tried Project -> Clean.A warning on all xml files has also showed up: No grammar constraints (DTD or XML schema) detected for the document." Maybe that is why the code generation have stopped. Any idea how to get the R class generated again?

Apt while generating the resources, is it possible to provide a different package name for the generated R.java class. 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 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.

public String getStr(){
return str;

public void setStr(String s){
str = s;

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

and i am just doing like from other class. GsonParser obj=new GsonParser(this);passing obj to activity class.how can i achieve that.
I've been working on a project for several weeks now, and just tonight I started having a problem. The R.java file is no longer being generated. I've attempted to clean the project (the first time I do this it removes the R.java file but doesn't regenerate it) and have tried uninstalling and reinstalling the SDK. I've also tried resetting adb to no avail.
This problem does not occur in my other Android projects. They clean just fine and regenerate the R.java file like nothing is wrong. This particular project is the only one suffering from this problem.
In my app in one package there are some classes. from those classes i want to run one class that is the Gps functionality class. i want to run that class in background. how i do it, i don't know. i am not able to make it solve from any document. if anybody knows the way to solve it please me by run a "hello world" app in the background. i am not able to solve this problem by going through document.

What exactly does the "MyService.class" field represent? Is that just a reference to the class for a template?

I am doing the Notepad tutorial, exercise 2. I started by creating a new Android project and chose Create from source to import the downloaded source files for the excercise. But now I get many errors in Eclipse, and the problem is that there is no generated R.java class. How can I solve this? The folder gen / is empty. I have errors on Notepadv2.java and in res/layout/note_edit.xml and both seems to be related to the fact that the generated R.java is missing. Here is my import statements in Notepadv2.java:
import android.R;
import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
They are created by the Eclipse command Ctrl+Shift+O.
I am currently working on a project which requires me to use an XML document to render a form on an Android device. The form must be fetched and displayed at run-time.

View 3 Replies View RelatedIf the BACK button is pressed when the soft keyboard is being displayed, no Back keycode event is generated (when it's not shown, and Back is pressed, then my View's onKeyDown()/onKeyUp() methods get called back).
Is this expected behaviour? I'm trying to catch when the IME is hidden upon BACK being pressed. I'm currently working around this in the endBatchEdit() method (I'm implementing BaseInputConnection).
I have a programmatically generated image that I want to send as an attachment via the ACTION_SEND and EXTRA_STREAM method. But how do i do this? My first attempt (writing to my context.getCacheDir() based file path) appeared to work in the Gmail preview (no image preview, but attached file name and icon was visible), but the attachment never arrived on the recipient side. I guess this has something to do with permissions on the generated file, but how to avoid this? Do I need to set more permissive settings on these generated files (so that the Gmail activity can access)? Is that even possible for the app's cache folder?
Is there another file location that would be more suitable to write my files to? I considered the downloads folder, but think it would be an awkward location for something that only needs to exist until it has been emailed. I have even tried encoding my image purely in a data:image/png;base64,ABCD... style URI. This, too, showed up in Gmail preview (attachment icon, but no file name), but did not result in a recipient-side attachment. Has anyone been able to attach a one-shot generated image to an email intent by any means? What options may I have overlooked?
Is there (or should there be), a generateId() method for dynamically generated Views? Take the RadioGroup example in APIDemos|App|Views. Radio buttons are added dynamically. For each button, you have to call setId(). To be notified when a radio button is selected, you register a onCheckedChange listener on RadioGroup and the callback method is oncheckedChange(RadioGroup, int checkedId). Since we are notified only the id of the checked view, shouldn't there be a way to uniquely generate the id? Say, a View.generateId() method... In the example, the ids are statically defined in ids.xml. However this limits the number of radio buttons. I have a real world example too: a Radiogroup with each choice representing a Wifi hotspot. So one cannot know in advance the number of hotspots.
View 10 Replies View RelatedI have a button that launches the google maps app on my device via an intent. I want to be able to pass it a php page that generates a KML file.

My php file is as follows;

It launches maps, finds the file - but won't display it 'because it contains errors'.
Is this just not possible, or are there other ways to construct the intent that might work?

I have a similar query to the one posted here. I create a grid consisting of a variable number of buttons, at runtime (in a TableLayout), and would like to find the index of the button pressed. The actual Button objects are currently stored in an array, although I'm not sure if that is really necessary. I tried to write the ClickListener using something along the lines of code...
but this just always returns -1. Is it possible to get the id (or some other reference to the button pressed) without predefining the buttons in xml?
The solution in the other post describes cycling through the whole array of Buttons and comparing ids. Is there a more elegant way to do this?
Is that normal that Images indexed in the MediaStore do not have thumbnails generated until the Gallery app is launched and the user actively navigates to the bucket where the image is stored ?
I think it's quite odd as I thought thulbnails generation was part of media indexing.

View 3 Replies View RelatedI'm using an ant build file that has been generated by android. Our Android application requires a JAR file that lives inside the lib folder of our project, so I need to adjust the classpath that ant is using when it builds stuff.
When I run:

the project builds just fine, but this should really be inside the build file itself. The build file that android generates references the android_rules.xml so a lot of this stuff is automated. I guess my question, what the best practice here when working with the Android build rules ?
