I am trying to access all of the WeChat contacts in my Android app and open Chat page with the contact on WeChat if the user taps on it. I read the official documentation from Here but it didn't help. I couldn't find any helpful answers anywhere else either. In my code, I am filtering contacts by MIME Type but I am getting an empty string every time. Please help me solve it...
//MIMETYPE of WeCha
String mimeString = "vnd.android.cursor.item/vnd.com.tencent.mm.chatting.voip.video";
String displayName = null;
String phone = null;
Long _id;
ContentResolver resolver = getApplicationContext().getContentResolver();
//Sorting contacts Alphabetically
Cursor cursor = resolver.query(ContactsContract.Data.CONTENT_URI, null, null, null, ContactsContract.Contacts.DISPLAY_NAME);
while (cursor.moveToNext()) {
_id = cursor.getLong(cursor.getColumnIndex(ContactsContract.Data._ID));
phone = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
//Getting the MimeType of user
String mimeType = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.MIMETYPE));
If(mimeType==mimeString)
{
//Logs for debugging
Log.d("Look here", _id.toString());
Log.d("Look here", displayName);
Log.d("Look here", mimeType);
}
}
cursor.close();

Hey so I just made an android app which basically fetches all the mp3/wav files from your phone and then shows them it to you. Which you can then play them. But I am experiencing slow load times. My phone has like 10 mp3 and its a 6GB RAM phone. But it takes like 1 minute to load all those files. I am using the built in MediaPlayer Class. Any tips?
Use this code.
for reference link
public void getMp3Songs() {
Uri allsongsuri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
String selection = MediaStore.Audio.Media.IS_MUSIC + " != 0";
songsList.clear();
Cursor cursor = managedQuery(allsongsuri, null, selection, null, null);
if (cursor != null) {
if (cursor.moveToFirst()) {
do {
String song_name = cursor
.getString(cursor
.getColumnIndex(MediaStore.Audio.Media.DISPLAY_NAME));
int song_id = cursor.getInt(cursor
.getColumnIndex(MediaStore.Audio.Media._ID));
String fullpath = cursor.getString(cursor
.getColumnIndex(MediaStore.Audio.Media.DATA));
songsList.add(fullpath);
String album_name = cursor.getString(cursor
.getColumnIndex(MediaStore.Audio.Media.ALBUM));
int album_id = cursor.getInt(cursor
.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
String artist_name = cursor.getString(cursor
.getColumnIndex(MediaStore.Audio.Media.ARTIST));
int artist_id = cursor.getInt(cursor
.getColumnIndex(MediaStore.Audio.Media.ARTIST_ID));
} while (cursor.moveToNext());
}
cursor.close();
}
Toast.makeText(context, ""+songsList.size(), Toast.LENGTH_SHORT).show();
}
Because of the Android Privacy Changes in Android Q (API29) it's not possible to add songs to a Playlist and it throws this error message when adding a track.
java.lang.SecurityException: com.mp3player.mp3player has no access to content://media/external_primary/audio/media/117
I know that we can this catch this as a RecoverableSecurityException and grant permission for each file individually.
But this is really a hassle and i'm wondering if there is another way.
I already found a post from User #Theo with the same exact problem but without any answers.
Code for adding songs to a playlist
public void addToPlayList(Context c, long songID, long playListID, String playlistName) {
Uri playListUri = MediaStore.Audio.Playlists.Members.getContentUri("external", playListID);
String[] columns = {
MediaStore.Audio.Playlists.Members.AUDIO_ID,
MediaStore.Audio.Playlists.Members.PLAY_ORDER,
};
ContentResolver resolver = c.getContentResolver();
Cursor cursor = resolver.query(playListUri, columns, null, null, null);
int playOrder = 0;
if (cursor != null) {
cursor.moveToFirst();
while (!cursor.isAfterLast()) {
playOrder = cursor.getInt(0) + 1;
}
cursor.close();
ContentValues contentValues = new ContentValues();
contentValues.put(MediaStore.Audio.Playlists.Members.AUDIO_ID, songID);
contentValues.put(MediaStore.Audio.Playlists.Members.PLAY_ORDER, playOrder);
resolver.insert(playListUri, contentValues);
resolver.notifyChange(Uri.parse("content://media"), null);
}
EDIT
Looks like the thrown Exception is not an instance of RecoverableSecurityException so how do we get access to that content?
you can use playListUri.getpath() and solve it.
TelephonyManager getSubscriberId() and getSimSerialNumber() return null in android Q!
I'm coding in java with android studio IDE!
TelephonyManager telephonyManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
telephonyManager.getSimSerialNumber(); //it is null
If your apk's targetsdk <30, you can get ICCID by the following method without any permission even in android 11.
Uri uri = Uri.parse("content://telephony/siminfo");
Cursor cursor = null;
ContentResolver contentResolver = getApplicationContext().getContentResolver();
cursor = contentResolver.query(uri,
new String[]{"_id", "sim_id", "imsi","icc_id","number","display_name"}, "0=0",
new String[]{}, null);
if (null != cursor) {
while (cursor.moveToNext()) {
String icc_id = cursor.getString(cursor.getColumnIndex("icc_id"));
String imsi_id = cursor.getString(cursor.getColumnIndex("imsi"));
String phone_num = cursor.getString(cursor.getColumnIndex("number"));
String display_name = cursor.getString(cursor.getColumnIndex("display_name"));
int sim_id = cursor.getInt(cursor.getColumnIndex("sim_id"));
int _id = cursor.getInt(cursor.getColumnIndex("_id"));
Log.d("Q_M", "icc_id-->" + icc_id);
Log.d("Q_M", "imsi_id-->" + imsi_id);
Log.d("Q_M", "phone_num-->" + phone_num);
Log.d("Q_M", "sim_id-->" + sim_id);
Log.d("Q_M", "display_name-->" + display_name);
}
}
public String getSimSerialNumber ()
Returns the serial number of the SIM, if applicable. Return null if it is unavailable.
Requires Permission: READ_PRIVILEGED_PHONE_STATE, for the calling app to be the device or profile owner and have the READ_PHONE_STATE permission.
See the following link:
getSerialNumber()
Also if are your app is can be selectable as default SMS app you can get this data without need any permissions.
For set your app as the default SMS app please look that page
Is there a way of determining the number of total messages in our device.
I've tried the following for finding the number of calls:
Uri allCalls = Uri.parse("content://call_log/calls");
Cursor c = managedQuery(allCalls, null, null, null, null);
count= c.getCount();
Log.i("TAG",Integer.toString(count));
But I'm not able to view any number when i tried this similar to messages in my logcat.
Try this code to get all Messages
public List<String> getSMS(){
List<String> sms = new ArrayList<String>();
Uri uriSMSURI = Uri.parse("content://sms/inbox");
Cursor cur = getContentResolver().query(uriSMSURI, null, null, null, null);
while (cur != null && cur.moveToNext()) {
String address = cur.getString(cur.getColumnIndex("address"));
String body = cur.getString(cur.getColumnIndexOrThrow("body"));
sms.add("Number: " + address + " .Message: " + body);
}
if (cur != null) {
cur.close();
}
return sms;
}
Just Call the method and you will receive an ArrayList of all messages
Get List of Messages in Inbox Like Below:
First Add Permission in Manifest.xml to read sms:
<uses-permission android:name="android.permission.READ_SMS"></uses-permission>
public ArrayList<String> fetchInbox()
{
ArrayList<String> sms = new ArrayList();
//Read Draft message only by "content://sms/draft"
//Read Sent message only by "content://sms/sent"
Uri uriSms = Uri.parse("content://sms/inbox");
Cursor cursor = getContentResolver().query(uriSms, new String[]{"_id", "address", "date", "body"},null,null,null);
cursor.moveToFirst();
while (cursor.moveToNext())
{
String address = cursor.getString(1);
String body = cursor.getString(3);
sms.add(body);
}
return sms;
}
And You can get SMS count by sms.size();
I have an activity that has a listview which displays all contacts with multi-selection enabled. I have also a filter to filter the display result.
After struggling with this problem for 3 days, I finally could produce a list of all display names selected by the user.
My question now is how to get the corresponding email and phone number for each display name in my list?
Update:
I found a solution..
public String getNumber(String name,Context context){
String number="";
Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER};
Cursor people = context.getContentResolver().query(uri, projection, null, null, null);
int indexName = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
people.moveToFirst();
do {
String Name = people.getString(indexName);
String Number = people.getString(indexNumber);
if(Name.equalsIgnoreCase(name)){return Number.replace("-", "");}
// Do work...
} while (people.moveToNext());
if(!number.equalsIgnoreCase("")){return number.replace("-", "");}
else return number;
}
public String getEmail(String name,Context context){
String email="";
Uri uri = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
String[] projection = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Email.DATA};
Cursor people = context.getContentResolver().query(uri, projection, null, null, null);
int indexName = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
int indexNumber = people.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA);
people.moveToFirst();
do {
String Name = people.getString(indexName);
String mail = people.getString(indexNumber);
if(Name.equalsIgnoreCase(name)){return mail;}
// Do work...
} while (people.moveToNext());
if(!email.equalsIgnoreCase("")){return email;}
else return email;
}
Got it from there:
