Title Body

I am writing an application which writes contacts in the SIM card of an Android phone. I am stuck at the point where the phone number is added: an exception occurs with no apparent reason. Here is a snippet of code. import android.app.Activity; import android.content.ContentResolver; import android.content.ContentUris; import android.content.ContentValues; import android.provider.ContactsContract.RawContacts; import android.provider.ContactsContract.Data; import android.provider.ContactsContract.RawContactsEntity; import android.provider.ContactsContract.CommonDataKinds.Phone; import android.provider.ContactsContract.CommonDataKinds.StructuredName; import android.provider.ContactsContract.RawContacts.Entity; import android.database.Cursor; import android.net.Uri; import android.os.Bundle; import android.widget.TextView; [...] try{ // add a row to the RawContacts table ContentValues values = new ContentValues(); values.put(RawContacts.ACCOUNT_TYPE, "com.anddroid.contacts.sim"); values.put(RawContacts.ACCOUNT_NAME, "SIM"); Uri rawContactUri = getContentResolver().insert(RawContacts.CONTENT_URI, values); // get the ID of the newly-added line long rawContactId = ContentUris.parseId(rawContactUri); // add a "name" line to the Data table, linking it to the new RawContact // with the CONTACT_ID column values.clear(); values.put(Data.RAW_CONTACT_ID, rawContactId); values.put(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE); values.put(StructuredName.DISPLAY_NAME, "Name"); cr.insert(Data.CONTENT_URI, values); // this insert succeeds // add a "phone" line to the Data table, linking it to the new RawContact // with the CONTACT_ID column values.clear(); values.put(Data.CONTACT_ID, rawContactId); values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE); values.put(Phone.NUMBER, "+12345678901"); valu
