Android :: Why "R" Resource File Is Not Generated?

Oct 17, 2010

Again and again I have the case that during development, the Android SDK suddenly doesn't regenerate the "R" file. Usually this is due to some error in one of the many .xml files, but that darn thing doesn't give the slighted indication, as to WHY it suddenly refuses to regenerate that file. There is no error or warning listed for any of my .xml files and manually checking all those (meanwhile almost hundred!) XML files for errors is no real fun, either! Is there some option or log or something that would allow to locate the problem quicker and more direct? Last time I had to do a lengthy binary search (i.e. copying and removing files to/from a second test project) trying to locate the offending file. That's really a nightmare and not how it should be in any decent SDK that deserves that name!

Android :: How To Use Resource Within A Custom Xml Resource File?

Aug 3, 2010

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?

Android :: No Generated R Java File In Project

Nov 3, 2010

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.

Android :: Getting Maps To Accept A Dynamically Generated KML File

Mar 18, 2010

I 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.

I have done this on a website before using the googlemaps api in JS - but it doesn't seem to work on Android.

My php file is as follows;

CODE:..............

Launching with:

CODE:.................

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?

Android :: Specify Lib Folder For JARs When Using Droid-generated Ant Build File?

Apr 9, 2010

I'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:

ant -lib lib debug

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 ?

Android : Can SAX Use A Local Resource XML File?

Jul 26, 2010

All of the android examples for XmlPullParser pull from a local resource file, and all of the SAX examples pull the XML from a URL. I've been told SAX is faster, so I'm trying to use that to pull data from a local resource file (res/xml/thefile.xml)

The example code I'm working off of is here. So in that example, the code I want to change is:

URL url = new URL("http://example.com/example.xml");
...
xr.parse(new InputSource(url.openStream()));

Instead of using URL, I want to use getXml(R.xml.thefile)
Is that possible, or does SAX need to get data from a URL?

Android :: Instantiating A Layout From An Xml File / Resource Id

Jan 28, 2009

I'm interested in instantiating a LinearLayout object from an xml file that has a LinearLayout file configuration. I want to do this within a method of my Activity. I tried findViewById() but that returned null. I've made sure that the LinearLayout id is the one I'm passing. Note that this layout isn't part of my screen, it's stand-alone, so I want to build a LinearLayout object from the xml.

Android :: Read Text File As Resource

Sep 14, 2010

I am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:

CODE:...................

However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.

I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.

Android :: Loading Raw Resource Text File / Out Of Memory Error

I use this method couples of occasion to load text file to display as help file. But I don't know why the following code didn't work. It seems to hang and logcat says "OutOfMemoryError"? All I did was break this out as an separate activity.

---xml---

android:id="@+id/helptab"
android:orientation="vertical"

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

super.onCreate(savedInstanceState);
setContentView(R.layout.help);
InputStream iFile = getResources().openRawResource(R.raw.help);
try { TextView helpText = (TextView) findViewById(R.id.helptext);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
} catch (Exception e) {
} }
public String inputStreamToString(InputStream is) throws IOException {
StringBuffer sBuffer = new StringBuffer();
DataInputStream dataIO = new DataInputStream(is);
String strLine = "";
while ((strLine = dataIO.readLine()) != "") {
sBuffer.append(strLine + " ");
} dataIO.close();
is.close();

Android :: Unbundled / Copy Raw Resource Binary File To Sd Card

Mar 2, 2009

I'm trying to unbundle a binary file (sound1.ogg) and store it on the sdcard.So it starts out as a raw resource (R.raw.sound1) and should end up as a copy named /sdcard/ mydir/sound1.ogg I wrote a method called something like copyResourceToFile() and did a copy via file descriptors / streams. But the target file just isn't right.If I do a buffered read, the target file ends up being WAY bigger - like 10x bigger.If I just do a byte-by-byte read for the size of the original file, the target file is the right size but is not the same file. Is there a simpler (well, correct/working) way to do this thing?

Android :: Resource Not Found Errors For Images - Button Selector XML File

Jan 5, 2010

My 1.6 app works fine in both portrait and landscape modes on the default HVGA device. I'm now trying to support it on QVGA devices and am encountering build-time errors I don't understand. In my res/drawable-ldpi directory I have:

startstopin.png startstopout.png and a selector file
startstopbuttonimageselector.xml
which contains:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable-ldpi/startstopin" />
<!-- pressed --> <item android:drawable="@drawable-ldpi/startstopout" />
<!-- default --> </selector>

I've 'fixed project properties' and done a 'clean' build, to no avail. The error I get is:
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopin').
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopout').
I've tried adding a layout file in res/layout-small that explicitly references this selector file, but this triggers a similar build error and fails to address the original problem:
Error: No resource found that matches the given name (at 'src' with value '@drawable-ldpi/startstopbuttonimageselector').

Android :: R.java Is Not Being Generated

Jul 23, 2009

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.
