[android-developers] Android SSL Socket problem
Hi all, im developing an android aplication and im facing some
problems with SSL. I tested the SSL communication between my server
and a java client at it works without problems, and now im having
problems trying to code an android client.
I imported my truststore on res/raw folder and so on, but the main
problem (even if i read the API) is that I dont know how to create the
sockets to comunicate with the server using that keystore. For example
I tried this:
InputStream mIS =
context.getResources().openRawResource(R.raw.truststoreclient);
keyStore = KeyStore.getInstance(BKS);
keyStore.load(mIS, aquabona.toCharArray());
mKMF = KeyManagerFactory.getInstance(X509);
mKMF.init(keyStore,
truststoreclient.toCharArray());
KeyManager[] mKM = mKMF.getKeyManagers();
SSLContext sc = SSLContext.getInstance(TLS);
TrustManagerFactory tmf =
TrustManagerFactory.getInstance(X509);
tmf.init(keyStore);
sc.init(mKM, tmf.getTrustManagers(), new
java.security.SecureRandom());
SSLSocketFactory sslsocketfactory = new
SSLSocketFactory(keyStore);
//Si hacemos la consulta a un unico servidor
if (ips.size() 2 ipPorts.size() 2) {
String singleServer = ips.get(0);
int singlePort =
Integer.parseInt(ipPorts.get(0));
Socket soc = sslsocketfactory.createSocket();
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params,
HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params,
utf-8);
params.setBooleanParameter(http.protocol.expect-
continue, false);
Socket socket =
sslsocketfactory.connectSocket(soc,
singleServer, singlePort, null, 0, params);
And now im having problems with certificates...
So is there an easier way to code up a SSL socket implementation on
android that uses that keystore?
Post some code, examples or ideas please.
Thanks all.

[android-developers] Listview and autocomplete problems!
Hi all!
Im trying to fill an autocompletetextview with data that i retrieve
from a database, so the next time we do a search that data will be in
the autocompletetextview suggestions.
The problem is that, I can view the listView associated with the
autocompletetextview (and it retrieves the data from the database
without any problem), but if i click on a single element of the
textview instead of having the string I picked on the autocomplete
textview I have an string like sql.cur...@
I dont have any problems with the database as I followed the notepad
tutorial and it works well.
Thank you all and here is the code:

[android-developers] Re: Dynamic TableLayout problem
Ok, solved y just have to use final on the tablelayout statement. If
someone wants the code ill post it.
Thanks for your reply Beth.

David,
The output shows you have a null pointer at line 93 of your activity.
Look there for a solution.
Also, I noticed you have System.out.println. Where are you expecting
the println output to appear? You might want to replace that with
Android.util.log.
Regards,
Beth

Hi! Im having a problem with a tablelayout. Im trying to add rows
dinamically and display the content of these rows (there are not
content problems as T tested it and the app has all the data that it
needs).
This is the java code and the xml of the activity:
[syntax=java]import java.util.ArrayList;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;
public class DisplayResult extends Activity{
/** Called when the activity is first created. */
�...@suppresswarnings(unchecked)
public void onCreate(Bundle savedInstanceState) {
System.out.println(2º actividad lanzada);
super.onCreate(savedInstanceState);
setContentView(R.layout.displayresults);
Bundle extras = getIntent().getExtras();
//this.setContentView(R.layout.main);
/* Find Tablelayout defined in main.xml */
TableLayout tl = (TableLayout)findViewById
(R.layout.displayresults);
ArrayList finalResults;
if(extras!=null){
finalResults = (ArrayList) (extras.getSerializable
(RemoteIR.RESULTS));
Iterator it = finalResults.iterator();
while(it.hasNext()) {
SearchResult result = ((SearchResult) it.next());
/* Create a new row to be added. */
TableRow tr = new TableRow(this);
tr.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
TextView title = new TextView(this);
title.setText(result.title.toString());
//System.out.println(title.getText());
TextView author = new TextView(this);
author.setText(result.author.toString());
TextView file = new TextView(this);
file.setText(result.file.toString());
TextView modDate = new TextView(this);
author.setText(result.modDate.toString());
TextView size = new TextView(this);
size.setText(result.size.toString());
title.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
author.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
file.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
modDate.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
size.setLayoutParams(new LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
tr.addView(title);
tr.addView(author);
tr.addView(file);
tr.addView(modDate);
tr.addView(size);
tl.addView(tr,new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
}
}
}
}[/syntax]
This is the xml:
[syntax=xml]
?xml version=1.0 encoding=utf-8?
TableLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:id=@+id/DisplayResults
android:layout_width=fill_parent
android:layout_height=fill_parent
TableRow
TextView
android:layout_column=1
android:text=Title
android:padding=3dip /
TextView
android:text=Author
android:padding=3dip /
TextView
android:text=File
android:padding=3dip /
TextView
android:text=ModDate
android:padding=3dip /
TextView
android:text=Size
android:padding=3dip /
/TableRow
/TableLayout[/syntax]
And this is the error that is frustrating me :s
