 As per normal content observer, you will just get to know that content
has been changed but not the data.

So how can I exactly find out what changes has been made using Content
Observer?
Is there any alternative way to obtain the changes done on specific
content URI?

Thanks a lot in advance !!

Thanks

1. AlarmManager - problem

Hello,
I'm new here so greetings to all.

Here is my problem:

I want to: Start MyApp after boot.

Code below gives me:
1. when I manualy run MyApp it works correctly. Gives me Alert HELLO.
2. After reboot system gives my info:
"The application MyApp (process test.test)  has stopped unexpectedly.
Please try again."

Any idea ? I have tried almost all ( commented lines) and still
nothing.

Here goes the Code:
MyApp.java:
[code]
package test.test;
public class TabletDambonia extends Activity {
 /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       Biblioteka.make_alert("HELLO", "blebleble", this );
   }
}
[/code]

Biblioteka.java:
[code]
package test.test;

import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.Gravity;
import android.widget.Toast;

public class Biblioteka {
    public static void generuj_alert( String title, String msg,
TabletDambonia tablet_dambonia ){
        AlertDialog alertDialog = new
AlertDialog.Builder( tablet_dambonia ).create();
        alertDialog.setTitle(title);
        alertDialog.setMessage(msg);
        alertDialog.setIcon(R.drawable.quan);
        alertDialog.setButton("OK", new
DialogInterface.OnClickListener() {
          public void onClick(DialogInterface dialog, int which) {
            return;
        } });

        alertDialog.show();
    }

}
[/code]

BootUpReceiver.java:
[code]
package quanGodziny.quanGodziny;

import java.util.Calendar;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class BootUpReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            AlarmManager am = (AlarmManager)
context.getSystemService(Context.ALARM_SERVICE);
           // Intent serviceIntent = new Intent(context,
TabletDambonia.class);
           // PendingIntent pi = PendingIntent.getService(context, 0,
serviceIntent, PendingIntent.FLAG_UPDATE_CURRENT);
           // Calendar calendar = Calendar.getInstance();
            Intent serviceIntent = new Intent(context, TabletDambonia.class);
            PendingIntent pi = PendingIntent.getActivity(context, 0,
serviceIntent, PendingIntent.FLAG_UPDATE_CURRENT);
            Calendar calendar = Calendar.getInstance();
            long triggerAtTime = calendar.getTimeInMillis() + (1 * 1 * 60 *
1000);   // starts in 60 sec
          //  am.setInexactRepeating(AlarmManager.RTC_WAKEUP, triggerAtTime,
repeat_alarm_every, pi);
            am.set(AlarmManager.RTC_WAKEUP, triggerAtTime, pi);
        }
}
[/code]

2. com.android.phone.CallTime

Hi,

I have to write an application which notifies the user in every
minute. I have tried Timer, but it is unreliable, the notification
almost always late.

I found that com.android.phone.CallTime can be used for that, but how
can I utilize this class?

Thanks for your help in advance.

Endre
