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?

I am trying to get googlemaps to accept a local KML file.
final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=file://" + Environment.getExternalStorageDirectory() + "/locate.kml"));
startActivity(myIntent);
The file is on the SD card, and is a valid KML file. Google Maps loads up, but says it cannot find the file.
final Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW,
Uri.parse("geo:0,0?q=http://www.website.com/locate.kml"));
startActivity(myIntent);
Works fine. geo: 0,0? q= seems to be very under documented, how to use it to refer to a local file?

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.

I accept and share my location however it doesn't set. It won't add the friends to my list, and if I exit and go back it shows the requests again.

Ive tried giving Ant more memory by setting ANT_OPTS="-Xms256m -Xmx512m". (This build machine has 1Gb RAM). Do I just need more memory or is there anything else I can try?

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.

Another day, another Android feature missing it seems. Someone has just sent me a VCF file with their contact details. I can open it - it opens up as plain text which is not very useful. (a) How can I get this into my contacts? (b) Can I send my own VCF back?

When I make a new project the .java file is not generated. I can run the project, but it does not run in the emulator or anything. It did use to work before then it stop working. I tried deleting the folder and all project files. After that I reinstalled everything but I am still having problems.

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 ?

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!

I'm currently developing an app for Android which uses google map service. Because users will be able to see thousands of markers I would like to load only those which are currently within the map bounds (i.e. when user look at specific map tile). I know how to do it with javascript/html. However, Android doesn't seem to provide any similar methods such as containsLatLng(latlng) or getBounds (I only found getLatitudeSpan and getLongitudeSpan, but don't know how can I use them in order to achieve the similar effect). Can anyone give me some hint on that?

I am storing the required test.jar file in the /sdcard. I want to load it dynamically at runtime and want to execute a function xyz() resides in that. For this purpose I had written following code:
But got ClassCastException : dalvik.system.PathClassLoader
Following is my code ,
import java.io.File; import java.io.IOException; import java.lang.reflect.InvocationTargetException; import java.lang.reflect.Method; import java.net.URL; import java.net.URLClassLoader;
import android.app.Activity; import android.os.Bundle; import android.util.Log;
public class Collabera extends Activity {
/** Called when the activity is first created. */
private static final Class[] parameters = new Class[] { URL.class };
public static void loadURLClass(String classPathURL) throws IOException {
File f = new File(classPathURL);
URL url = f.toURL();
URLClassLoader systemLoader = (URLClassLoader) ClassLoader.getSystemClassLoader();
Class systemLoaderClass = URLClassLoader.class;
try { Method method = systemLoaderClass.getDeclaredMethod("addURL", parameters);
method.setAccessible(true);
method.invoke(systemLoader, new Object[] { url });
} catch (Throwable t) { t.printStackTrace();
throw new IOException( "Error, could not add URL to system classloader");
} }
@Override
public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Log.i("See","**************Before Loading Class Path**************");
try { Class.forName("test.Test1");
} catch (ClassNotFoundException e) { System.out.println(" Test Class Not Found ....");
} Log.i("See","**************After Loading Class Path**************");
try { loadURLClass("//sdcard//test.jar");
Class c = Class.forName("test.Test1");
Log.i("See"," Test Class Found ....");
Method method = c.getMethod("xyz", null);
Object o = c.newInstance();
String s = (String) method.invoke(o);
Log.i("See","Got method: " + s);
} catch (ClassNotFoundException e) { System.out.println(" Test Class Not Found ....");
} catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace();
} } }

I have an XMl file like below which I will use to set background for Textview:
row.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
The above Xml I will set as background for TextView in main.xml as below:
main.xml
<TextView
android:id="@+id/rowtext3"
android:text="Availablity"
android:layout_height="25px"
android:layout_width="60px"
android:textSize="10px"
android:textStyle="bold"
android:textColor="@color/black"
android:gravity="center"
android:background="@drawable/row"/>
But I want this to do from code rather than Xml.I have done everything that I have done in Xml like font,width,Height,font dynamically through code , but not able to set Background that I mentioned in Xml file . How can we set content of Xml file as background to textview similar to how we set background as XML in main.xml.
In the code I have done like this:
t1=new TextView(this);
t1.setText(ed1.getText());
t1.setHeight(25);
t1.setWidth(60);
t1.setTextSize(10);
But I didn't find how to set background i.e. how to set XML content as background?

I'm trying to get and display a live .kml file from maps.google.com using
CODE:.................
However after opening the mapview I get a notification saying "The community map could not be displayed because it contains errors"
I only get this error if I download the .kml directly from maps.google. If I copy the exact same link into my address bar, download the .kml file, and upload it elsewhere then it works fine. I would like to be able to get the maps directly from Google that way I can make a change and it would be immediately reflected to my users.

i just registered here to find out if opening a KML file on my SD card with Google maps in offline mode can work. I am looking for an solution quite a time, but only found this thread on stackover.
Quote:
To load kml into Google Maps on Android without writing an app, you can create a little html file somewhere with a geo-uri link to the kml file and then click on that link in any Android web browser.
For example: suppose your kml file is located in /sdcard/overlay.kml then you write a geo-uri link like this:
Quote:
<html>
<head><title>Example KML link page using a geo-uri</title></head>
<body>
<a href="geo:0,0?q=file:///sdcard/overlay.kml">overlay.kml</a>
</body>
</html>
Clicking on the link will launch Maps and then Maps will attempt to load and your kml.
Be warned however that the Android version of Maps does not appear to handle the same version/range of kml elements as the desktop version (or desktop Google Earth).
a other thread is about editing the manifest file to get maps to open local KML files
Quote:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="h**p://schemas.android.com/apk/res/android"
package="com.example.lyold"
[Code]....
Any way to open local KML files with google maps in offline mode ? I want to open kml ONLY in google maps, i know there are several apps out there that support kml files....

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?

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.

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. I am wondering if there is a way to tag the form XML, transform it using XSLT into an Android layout XML, and then have the device render it.

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.

If 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?
