I am trying to implement contact pciker in android, i am able to launch contact picker in android, but when i select the contact i get back null value, i.e. no number in my textfield. What am i doing wrong ?
Here is my code.

}
P.S. i have mentioned the permission in manifest.
From your code it seems to be you have not added onActivityResult method. Put the following code in in onActivityResult method
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
Uri contact = data.getData();
ContentResolver cr = getContentResolver();
Cursor c = managedQuery(contact, null, null, null, null);
while(c.moveToNext()){
String id = c.getString(c.getColumnIndex(ContactsContract.Contacts._ID));
String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(Phone.CONTENT_URI,null,Phone.CONTACT_ID +" = ?", new String[]{id}, null);
while(pCur.moveToNext()){
String phone = pCur.getString(pCur.getColumnIndex(Phone.NUMBER));
tv.setText( phone);
}
}
}}

I am android developer .I have face issue ANR when multiple image send in background using intent service.I have call service on Resume() method.I have update UI when step by step image upload finish .My all code in service .But i don't understand why my UI hang.I have created ResultReceiver class for Update UI.

There are many methods to upload more images to the server.. one could be including two libraries: apache-mime4j-0.6.jar and httpmime-4.0.1.jar.. After that create your java main code:

Now your layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Multiple File Upload from CoderzHeaven"
/>
<Button
android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get First File">
</Button>
<Button
android:id="#+id/Button02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Get Second File">
</Button>
<Button
android:id="#+id/upload"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Upload">
</Button>
<TextView
android:id="#+id/tv"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Selected File path : "
/>
<TextView
android:id="#+id/res"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text=""
/>
</LinearLayout>
of course, include the internet permission in your manifest:
<uses-permission android:name="android.permission.INTERNET" />
And voilà. Anyway i followed this example in my case: http://www.coderzheaven.com/2011/08/16/how-to-upload-multiple-files-in-one-request-along-with-other-string-parameters-in-android/ try to see there.. There are 4 methods to upload multiple files. See which you like
I am currently working with an Android content provider that i have created i use the query methode in a service because i have to update my result every 2 second my probleme is i want to get the last row in my databases, I put the sursor to the last position but every time his getting me all the data that he found in the database.
this is the service that I developed:
package fr.esigetel.echange.service;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Service;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.util.Log;
import fr.esigetel.mediatag.cp.WifiProvider;
public class informationService extends Service {
Timer mTimer;
private Handler mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
returnContentProvider();
}
};
#Override
public void onCreate() {
super.onCreate();
mTimer = new Timer();
Log.d("onCreate informationService", "onCreate informationService");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
mTimer.scheduleAtFixedRate(new TimerTask() {
#Override
public void run() {
mHandler.sendEmptyMessage(0);
}
}, 0, 5000);
return super.onStartCommand(intent, flags, startId);
}
#Override
public void onDestroy() {
if (mTimer != null) {
mTimer.cancel();
mTimer = null;
}
if (mHandler != null) {
mHandler = null;
}
super.onDestroy();
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
public informationService() {
}
private void returnContentProvider() {
Uri myuri = Uri.parse("content://fr.esigetel.mediatag.cp/maxdata");
ContentResolver cr = getContentResolver();
Cursor c = cr.query(myuri, null, null, null, null);
int idRech = c.getColumnIndex(WifiProvider.MAX_COL_ID);
int nameap = c.getColumnIndex(WifiProvider.MAX_COL_APName);
int adressemac = c.getColumnIndex(WifiProvider.MAX_COL_AdresseMac);
int rssi = c.getColumnIndex(WifiProvider.MAX_COL_RSSI);
int frequence = c.getColumnIndex(WifiProvider.MAX_COL_Freq);
int daterech = c.getColumnIndex(WifiProvider.MAX_Date);
c.moveToLast();
while (c.moveToPrevious()) {
int id = c.getInt(idRech);
String name = c.getString(nameap);
String mac = c.getString(adressemac);
int Rssi = c.getInt(rssi);
int Freq = c.getInt(frequence);
int Daterech = c.getInt(daterech);
try {
} catch (Exception e) {
System.out.println(e.getMessage());
}
Log.d("aaaaaa", name);
}
c.close();
}
How could i request only the last row of my database? this methode alway give me the whole data.
Cursor c = cr.query(myuri, null, null, null, null);
c.moveToLast();
Now Cursor Is At Last Possition And get The Last Record Data
int idRech = c.getColumnIndex(WifiProvider.MAX_COL_ID);
int nameap = c.getColumnIndex(WifiProvider.MAX_COL_APName);
int adressemac = c.getColumnIndex(WifiProvider.MAX_COL_AdresseMac);
int rssi = c.getColumnIndex(WifiProvider.MAX_COL_RSSI);
int frequence = c.getColumnIndex(WifiProvider.MAX_COL_Freq);
int daterech = c.getColumnIndex(WifiProvider.MAX_Date);
So here I want to have click event on pressing which i will have particular Category of location rather than search box for searching places. On pressing OnClickGPS it will open PlacePickerFragment of Facebook with search box at the top. But i want to search places category wise like Restaurent, Theatre, etc. on button click. Any assistance in this will be highly appreciable.

The best way to do this is to use the PlacePickerFragment, and call setSearchText("restaurant"). While it doesn't necessarily restrict it to a category, it will search everything that is categorized as a restaurant.
You can also see an example of this in the Scrumptious sample app (in the PickerActivity class).

msgs[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
str += "SMS from " + msgs[i].getOriginatingAddress();
str += " :";
trigger_message = msgs[i].getMessageBody().toString();

You have context passed as parameter to onRecieve() method, so just use:
#Override
public void onReceive(Context context, Intent intent) {
//start activity
Intent i = new Intent();
i.setClassName("com.test", "com.test.MainActivity");
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
It works, of course you have to change package and activity class name to your own.
I am using this and its work on my site:
Intent intentone = new Intent(context.getApplicationContext(), DialogAct.class);
intentone.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intentone);
Intent intent1 = new Intent();
intent1.setClassName(context.getPackageName(), MainActivity.class.getName());
intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);
to prevent those package exceptions
