Android get contact id from thread id - android

I'm working on a simple sms app and I'm using the code below to get the thread id when loading my threads list but I can't figure out how to get the contact id using the thread id. I'm root and using root explorer I can see in the database there is a contacts table with the following columns
thread_id | htcthread_id | contact_id
So since I have the thread id I should be able to get the contact id but I also need to make sure this works on all devices. My app is not root by the way
code to get thread id
Uri uri = Uri.parse("content://mms-sms/conversations?simple=true");
Cursor c = context.getContentResolver().query(uri, null, null, null, "date desc");
if (c.getCount() > 0) {
while (c.moveToNext()){
//thread id is c.getString(c.getColumnIndexOrThrow("_id"))
}
}
c.close

My solution to recover all contacts:
Cursor cursor = null;
try {
cursor = context.getContentResolver().query(Phone.CONTENT_URI, null, null, null, null);
int contactIdIdx = cursor.getColumnIndex(Phone._ID);
int nameIdx = cursor.getColumnIndex(Phone.DISPLAY_NAME);
int phoneNumberIdx = cursor.getColumnIndex(Phone.NUMBER);
int photoIdIdx = cursor.getColumnIndex(Phone.PHOTO_ID);
cursor.moveToFirst();
do {
String idContact = cursor.getString(contactIdIdx);
String name = cursor.getString(nameIdx);
String phoneNumber = cursor.getString(phoneNumberIdx);
//...
} while (cursor.moveToNext());
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cursor != null) {
cursor.close();
}
}
You need this permission in your manifest :
<uses-permission android:name="android.permission.READ_CONTACTS" />
I hope I have helped you!

All Contacts are not showing while retrieving contacts

I implemented a code to retrieve all contacts but it is not showing all contacts where few of them are missed.
Here is my code:
String[] projection = new String[]{
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER,
};
Cursor cursor = null;
try {
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
projection, null, null, null);
} catch (SecurityException e) {
}
if (cursor != null) {
try {
HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();
int indexOfNormalizedNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER);
int indexOfDisplayName = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexOfDisplayNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
while (cursor.moveToNext()) {
String normalizedNumber = cursor.getString(indexOfNormalizedNumber);
if (normalizedNumbersAlreadyFound.add(normalizedNumber)) {
String displayName = cursor.getString(indexOfDisplayName);
String displayNumber = cursor.getString(indexOfDisplayNumber);
listOfContacts.add(new PhoneContactsModel(displayName, displayNumber, false));
} else {
}
}
Log.d("tag", "size of listOfContacts =1====" + listOfContacts.size());
} finally {
cursor.close();
}
}
don't know what is happening. Please help me.
There are many issues in the code:
You're querying over the CommonDataKinds.Phone.CONTENT_URI table, so naturally, you won't get contacts that have no phone numbers (e.g. contacts with name and email)
You're skipping contacts that contains phones you've already encountered in normalizedNumbersAlreadyFound, so if you have two contacts with a shared phone (like a home phone number) you might skip one of them.
CommonDataKinds.Phone.NORMALIZED_NUMBER may be null, in which case you'll skip many contacts that do not have their NORMALIZED_NUMBER field set
If you need to also include contacts that have no phones, I would recommend a completely different code. If you only need to get contacts with phones, I would recommend not relying on NORMALIZED_NUMBER, and instead add CommonDataKinds.Phone.CONTACT_ID to your projection, and have that as your unique key per contact.

Error when read Android contacts

I've gotten this snippet from StackOverflow:
Cursor people = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
try{
while (people.moveToNext()) {
int nameFieldColumnIndex = people
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String number = people.getString(numberFieldColumnIndex);
System.out.println(contact + "-" + number);
}
}catch(Exception e){
System.out.println(e);
}
people.close();
When I try to read phoneNum column I get an error using String number = people.getString(numberFieldColumnIndex). Checking the column index I find that numberFiledColomnIndex = -1.
How can I get this snippet working?
Per the documentation, getColumnIndex() returns -1 when the column doesn't exist.
Q: Are you passing the correct column name? Is the spelling correct?

How to identify a local phone contact and an SYNC phone contact in android?

Can anybody guide me to find the solution for the following problem.
I have to identify whether the phone contact saved in locally or from Email ?(programatically)
i have read fromgoogle doc that ContactsContract.Groups, which contains information about raw contact groups such as Gmail contact groups. The current API does not support the notion of groups spanning multiple accounts.
Based on that i have tried the following code.
StringBuffer output = new StringBuffer();
final String[] GROUP_PROJECTION = new String[] {
ContactsContract.Groups._ID,
ContactsContract.Groups.TITLE,
ContactsContract.Groups.SUMMARY_WITH_PHONES
};
Cursor c = getContentResolver().query(
ContactsContract.Groups.CONTENT_URI, GROUP_PROJECTION, null,
null, ContactsContract.Groups.TITLE);
int IDX_ID = c.getColumnIndex(ContactsContract.Groups._ID);
int IDX_TITLE = c.getColumnIndex(ContactsContract.Groups.TITLE);
output.append("title"+IDX_TITLE+"\n");
Map<String,GroupInfo> m = new HashMap<String, GroupInfo>();
while (c.moveToNext()) {
output.append("test...\n");
GroupInfo g = new GroupInfo();
g.id = c.getString(IDX_ID);
g.title = c.getString(IDX_TITLE);
output.append("title"+c.getString(IDX_TITLE)+"\n");
int users = c.getInt(c.getColumnIndex(ContactsContract.Groups.SUMMARY_WITH_PHONES));
if (users>0) {
// group with duplicate name?
GroupInfo g2 = m.get(g.title);
if (g2==null) {
m.put(g.title, g);
output.append("title"+g.title+"\n");
groups.add(g);
} else {
g2.id+=","+g.id;
}
}
}
outputText.setText(output);
c.close();
but no hope.
I am posting this answer for future use. We can differentiate the local phone contacts and the sync contacts by using the field called RawContacts.SOURCE_ID
It is described here
SOURCE_ID
read/write
String that uniquely identifies this row to its source account. Typically it is set at the time the raw contact is inserted and never changed afterwards. The one notable exception is a new raw contact: it will have an account name and type (and possibly a data set), but no source id. This indicates to the sync adapter that a new contact needs to be created server-side and its ID stored in the corresponding SOURCE_ID field on the phone.
The sample code is follows, it gives the id for sync contacts and null for others.
private void testContact() {
StringBuffer output = new StringBuffer();
ContentResolver resolver = getContentResolver();
Cursor contacts = resolver.query(Contacts.CONTENT_URI, null,
Contacts.HAS_PHONE_NUMBER + " != 0", null, Contacts._ID
+ " ASC");
Cursor data = resolver.query(Data.CONTENT_URI, null, Data.MIMETYPE
+ "=? OR " + Data.MIMETYPE + "=?", new String[]{
Email.CONTENT_ITEM_TYPE, Phone.CONTENT_ITEM_TYPE},
Data.CONTACT_ID + " ASC");
int idIndex = contacts.getColumnIndexOrThrow(Contacts._ID);
int nameIndex = contacts.getColumnIndexOrThrow(Contacts.DISPLAY_NAME);
int cidIndex = data.getColumnIndexOrThrow(Data.CONTACT_ID);
int data1Index = data.getColumnIndexOrThrow(Data.DATA1);
boolean hasData = data.moveToNext();
while (contacts.moveToNext()) {
long id = contacts.getLong(idIndex);
Uri rawContactUri =
ContentUris.withAppendedId(RawContacts.CONTENT_URI, id);
Uri entityUri =
Uri.withAppendedPath(rawContactUri, Entity.CONTENT_DIRECTORY);
Cursor c =
getContentResolver().query(
entityUri,
new String[] {
RawContacts.ACCOUNT_NAME,
RawContacts.SOURCE_ID, Entity.DATA_ID, Entity.MIMETYPE, Entity.DATA1},
null, null, null);
try {
while (c.moveToNext()) {
String sourceId = c.getString(0);
if (!c.isNull(1)) {
String source_id = c.getString(1);
try {
output.append(c.getString(4)+sourceId+" "+source_id+"\n");
//output.append(datas+ "Sync1 "+ c.getString(4)+" Sync2 "+ c.getString(5)+" Sync3"+ c.getString(6)+" Sync4 "+ c.getString(7)+"\n");
} catch (Exception e) {
e.printStackTrace();
}
//decide here based on mimeType, see comment later
}
}
} finally {
c.close();
}
}
outputText.setText(output);
}
Have a read through this and see if ACCOUNT_TYPE might be able to help you

Android - MediaStore.Video.query() is returning null

I'm trying to retrieve the metadata from a video file (title, language, artist) using the method MediaStore.Video.query(). However, the method is always returning null. The code is bellow:
String[] columns = {
MediaStore.Video.VideoColumns._ID,
MediaStore.Video.VideoColumns.TITLE,
MediaStore.Video.VideoColumns.ARTIST
};
Cursor cursor = MediaStore.Video.query(getApplicationContext().getContentResolver(), videoUri,columns);
if (cursor != null) {
cursor.moveToNext();
}
String title = cursor.getString(cursor.getColumnIndex(MediaStore.Video.VideoColumns.TITLE));
Any suggestion about how to return video metadata using android?
==Update
As I searched in many places, I tried one solution using CursorLoader. However, the method loadInBackground() from CursorLoader is also returning null. The code is showed bellow:
String[] columns = {
MediaStore.Video.VideoColumns.TITLE
};
Uri videoUri = Uri.parse("content://mnt/sdcard/Movies/landscapes.mp4");
CursorLoader loader = new CursorLoader(getBaseContext(), videoUri, columns, null, null, null);
Cursor cursor = loader.loadInBackground();
cursor.moveToFirst();
String title = cursor.getString(cursor.getColumnIndex(MediaStore.Video.VideoColumns.TITLE));
Uri.parse("content://mnt/sdcard/Movies/landscapes.mp4") is not an Uri for MediaStore. It would try to find a ContentProvider for authority mnt which does not exist.
MediaStore can handle only content://media/... Uris which you should get exclusively via MediaStore, not by using Uri.parse().
In your case use the following for example
Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String[] columns = {
MediaStore.Video.VideoColumns._ID,
MediaStore.Video.VideoColumns.TITLE,
MediaStore.Video.VideoColumns.ARTIST
};
String selection = MediaStore.Video.VideoColumns.DATA + "=?";
String selectionArgs[] = { "/mnt/sdcard/Movies/landscapes.mp4" };
Cursor cursor = context.getContentResolver().query(uri, columns, selection, selectionArgs, null);
The MediaStore.Video.VideoColumns.DATA field holds the path to the videos and you search for a certain video this way. At least for now, future versions of Android may change that.
Your second example is using CursorLoader the wrong way. If you call loader.loadInBackground() yourself, you load the data in foreground. See e.g. http://mobile.tutsplus.com/tutorials/android/android-sdk_loading-data_cursorloader/
The next thing you do is
Cursor cursor = getCursor();
cursor.moveToFirst();
String title = cursor.getString(/* some index */);
This will lead to a CursorIndexOutOfBoundsException if your cursor has 0 rows and cursor.moveToFirst() failed because there is no first row. The cursor stays before the first row (at -1) and that index does not exist. That would mean in your case that the file was not found in the database.
To prevent that use the return value of moveToFirst - it will only be true if there is a first row.
Cursor cursor = getCursor(); // from somewhere
if (cursor.moveToFirst()) {
String title = cursor.getString(/* some index */);
}
A more complete example including checks for null and closing the cursor in all cases
Cursor cursor = getCursor(); // from somewhere
String title = "not found";
if (cursor != null) {
if (cursor.moveToFirst()) {
title = cursor.getString(/* some index */);
}
cursor.close();
}
I guess the file you try to find is either not indexed in the database (rebooting forces the indexer to run again) or the path is wrong.
Or the path you use is actually a symlink in which case MediaStore might use a different path.
Use this to get rid of symlinks
String path = "/mnt/sdcard/Movies/landscapes.mp4";
try {
path = new File(path).getCanonicalPath();
} catch (IOException e) {
e.printStackTrace();
}
Yes, I tested now and it is throwing IndexOutOfBoundsException. When I'm using cursor.getColumnCount() it returns 1
cursor.getColumnCount() is the column count, not the row count. It should always be the same as the number of columns you requested in columns. You need to check cursor.getCount() if you want to check the row count.
Try dumping all the videos known to MediaStore into logcat in case it does not show as expected.
public static void dumpVideos(Context context) {
Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaStore.Video.VideoColumns.DATA };
Cursor c = context.getContentResolver().query(uri, projection, null, null, null);
int vidsCount = 0;
if (c != null) {
vidsCount = c.getCount();
while (c.moveToNext()) {
Log.d("VIDEO", c.getString(0));
}
c.close();
}
Log.d("VIDEO", "Total count of videos: " + vidsCount);
}
I updated your code, it works, just check it
public static void dumpVideos(Context context) {
Uri uri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaStore.Video.VideoColumns.DATA };
Cursor c = context.getContentResolver().query(uri, projection, null, null, null);
int vidsCount = 0;
if (c != null) {
c.moveToFirst();
vidsCount = c.getCount();
do {
Log.d("VIDEO", c.getString(0));
}while (c.moveToNext());
c.close();
}
Log.d("VIDEO", "Total count of videos: " + vidsCount);
}

how to get the group id of a contact in android

I want to get the group id of each contact in my android application.I have initial query like this
Cursor cursor = cr.query(Phone.CONTENT_URI,
new String[] {
Phone.CONTACT_ID}, null, null, null);
And what i do is get details of each which related to this CONTACT_ID.I have manage to get phone number,names,addresses and emails so far but still couldn't manage to get the group id of the contact.
P.S i found a question asked before here but the class android.provider.Contacts.GroupMembership is deprecated.
thanks.
Try this:
final String selection = "mimetype_id = (select _id from mimetypes where mimetype = \"" +
vnd.android.cursor.item / group_membership + "\")";
Cursor cursor = getContentResolver().query(Data.CONTENT_URI,
new String[]{Phone.CONTACT_ID}, selection, null, null);
try {
if (cursor != null && cursor.moveToFirst()) {
do {
Log.i("Details", "Contact IDs" + cursor.getLong(cursor.getColumnIndex(Phone.CONTACT_ID)));
} while (cursor.moveToNext());
}
} finally {
if (cursor != null) {
cursor.close();
}
}
