I have been trying to pass the contact data from my second activity's list view to my main activity's list view, upon clicking the checkbox.But the data doesn't get transferred. How do I fix this?

logcat
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.artist.sender/com.example.artist.sender.contacts}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setOnItemClickListener(android.widget.AdapterView$OnItemClickListener)' on a null object reference
This is the logcat for the error. It keeps showing that the setitemOnClickListener keeps referring to a null object whereas, I've already assigned the listview to its respective id.
EDIT:**I've fixed part of the error, by renaming the setContentView(R.layout.activity_main); in the contacts class to setContentView(R.layout.contacts); But now after that, it shows this error, **java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference

If the data in the database, or some other storage, only pass the _id or the location, respectively.
Instead of passing many extras, Android way is, actually, Parcable. Here a nice tutorial from Vogella
public class TestModel implements Parcelable {
String name;
String phoneNumber;
//.....
#Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.name);
dest.writeString(this.phoneNumber);
}
public static final Parcelable.Creator<TestModel> CREATOR = new Parcelable.Creator<TestModel>() {
#Override
public TestModel createFromParcel(Parcel source) {
return new TestModel(source);
}
#Override
public TestModel[] newArray(int size) {
return new TestModel[size];
}
};

Android multiple contacts from groups and images

I want to do the following.
Pick up three to five contacts out of a special group of contacts or all contacts.
In the list it would be nice to show the contact image.
The selected contacts should have the following information (contact-id, first name, the small version of the contact image to save it as a blob in the database)
I found solutions for the different aspects.
-select multiple contacts:
How to obtain the checked rows in a custom view list
-show contacts from one group
getting contacts from a specified group in android
- photo problem
Getting a Photo from a Contact
But I dont know how to put those together. It would be great if someone could help me putting it together.
Thank you very much!

pls help frends

To check if a contact name already exists in the address book you could add...
public boolean contactExists(String contact) {
if (contact != null) {
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext()) {
if (contact.equalsIgnoreCase(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)))) {
return true;
}
}
}
return false;
}

Declare logNumbers and number as members of your SimonCallLogActivity class.
public class SimonCallLogActivity extends Activity {
/** Member variables */
EditText display;
Button log;
List<String> logNumbers = new ArrayList<String>();
EditText number;
...
...
}
Remove their local declarations..
