The reason is being behind the proxy.
As I'm not in the same position (no proxy), its really hard to help here.

can someone please explain the different values written in writeRequest Method:
| Java: | public void writeRequest(OutputStream outputStream) throws IOException {
DataOutputStream os = new DataOutputStream(outputStream);
os.writeShort(21);
os.writeLong(0);
os.writeUTF("fr");//country code
os.writeUTF("Sony_Ericsson-K750");//phone make
os.writeUTF("1.3.1");//software version
os.writeUTF("Web");//type
os.writeByte(27);
os.writeInt(0); os.writeInt(0); os.writeInt(3);
os.writeUTF("");
os.writeInt(myCellID); // CELL-ID
os.writeInt(myLAC); // LAC
os.writeInt(0); os.writeInt(0);
os.writeInt(0); os.writeInt(0);
os.flush();
}
|
|
Just trying this piece of code (only HTTP protocol part) to verify this "hidden" API.
I'm using value got from CellTrack application in my phone, and substitute above parameters.
It's working in my country (ID).
The two parameters after LAC is MNC and MCC according to this site: http://maps.alphadex.de/datafiles/fct0e1b117823ccc1a.txt .
It's locating my position with quite acceptable accuracy (I don't know how accurate it is, seems showing 1km radius of my position if it's checked using Google Map).

Is this example for A-GPS.
Is A-GPS related to this example in anyway. I want to know if there is any special API for A-GPS?

Hi phannguyen,
if you are working on android-sdk_m5-rc15 then change it to.
<Button id="@+id/cmd_update"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="Update"
/>
<Button android:id="@+id/cmd_update"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="Update"
/>
and also replace id with android:id everywhere in main.xml
May be it will resolve your issue.
Regards,
Brijesh

Hi phannguyen,
I also cant able to run this application.In my case it is showing the operation time-out error. I am behind proxy.and this application uses hidden api.
Check the error in LogCat.
May be that is the problem.
sorry for this time

Hi phannguyen,
LogCat is just like console.Its a console for Android.
If you are using eclipse.Click on Window Menu--->Show View-->Others-->Android--->LogCat.
After running the application.Check the Log Cat.It will show the the Application's Error.
The Problem is not in network.If you run this application with Direct Internet Connection may be it will run fine.But if you are Behind proxy it causes error.
Check the LogCat & post the error. You can get more details of LogCat from Android website.
Regards,
Brijesh
