I am developing an Android Application to wipe all data from Android including photos, videos, contacts, messages, apps,call logs, application data etc. programmatically. I wish to achieve this with an Android Application only and not through adb.
The approach I am thinking of somehow I manage to Clear data from phone and rewrite the memory with some junk files or binary data 1010 say. (Its just an idea!)
All I have managed to do is delete photos,videos,images,contacts,call logs,messages from Device using Cursor and getContentResolver. But we can recover that using third party Data Recover Softwares.
I have also reset the device using device administrator but the cons of this is the data can be recovered through it.
So, all i need is which approach to follow for hard resetting the device.
I have used below code .
public static void deleteAllContacts(Context activity) {
ContentResolver contentResolver = activity.getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext()) {
String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_LOOKUP_URI, lookupKey);
contentResolver.delete(uri, null, null);
}
}

I am new to android programming . I am trying to fetch all photos (or Image's path) reside in android device Internal Storage. I have written the function like this--
public static ArrayList<String> getImagesPath(Activity activity) {
Uri uri;
ArrayList<String> listOfAllImages = new ArrayList<String>();
Cursor cursor;
int column_index_data;
String PathOfImage = null;
uri = android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI;
String[] projection = {MediaStore.MediaColumns.DATA};
cursor = activity.getContentResolver().query(uri, projection, null, null, null);
column_index_data = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
while (cursor.moveToNext()) {
PathOfImage = cursor.getString(column_index_data);
listOfAllImages.add(PathOfImage);
}
return listOfAllImages;
}
Try this, hope it will work for you
public ArrayList<String> getFilePaths()
{
Uri u = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = {MediaStore.Images.ImageColumns.DATA};
Cursor c = null;
SortedSet<String> dirList = new TreeSet<String>();
ArrayList<String> resultIAV = new ArrayList<String>();
String[] directories = null;
if (u != null)
{
c = managedQuery(u, projection, null, null, null);
}
if ((c != null) && (c.moveToFirst()))
{
do
{
String tempDir = c.getString(0);
tempDir = tempDir.substring(0, tempDir.lastIndexOf("/"));
try{
dirList.add(tempDir);
}
catch(Exception e)
{
}
}
while (c.moveToNext());
directories = new String[dirList.size()];
dirList.toArray(directories);
}
for(int i=0;i<dirList.size();i++)
{
File imageDir = new File(directories[i]);
File[] imageList = imageDir.listFiles();
if(imageList == null)
continue;
for (File imagePath : imageList) {
try {

{
String path= imagePath.getAbsolutePath();
resultIAV.add(path);
}
}
// }
catch (Exception e) {
e.printStackTrace();
FirebaseCrash.report(e);
}
}
}
return resultIAV;
}
You can add any extension to get the files
It returns null, because cursor == null or cursor.getCount() == 0. Which means you don't have photos in your internal storage.
PS: Cursor should be freed after use.
if there any method to get contact name by send contact number in android.if any one have idea .
private String getContactName(String string) {
String name=null;
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,null,null,null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
}
return name;
}
I am sending contact number to these method.How to get contact name.
use following method to get contact, from contact provider:
Uri contactUri = Uri.withAppendedPath(Contacts.Phones.CONTENT_FILTER_URL, Uri.encode(string));
Cursor cursor = mContext.getContentResolver().query(contactUri, null, null, null, null);
This cursor will have resultset having number same as string.
I got it by do like these.
public static String getContactName(final String phoneNumber,Context context) {
Uri uri;
String[] projection;
Uri mBaseUri = Contacts.Phones.CONTENT_FILTER_URL;
projection = new String[] { android.provider.Contacts.People.NAME };
try {
Class<?> c = Class
.forName("android.provider.ContactsContract$PhoneLookup");
mBaseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(mBaseUri);
projection = new String[] { "display_name" };
} catch (Exception e) {
}
uri = Uri.withAppendedPath(mBaseUri, Uri.encode(phoneNumber));
Cursor cursor = context.getContentResolver().query(uri, projection, null,
null, null);
String contactName = "";
if (cursor.moveToFirst()) {
contactName = cursor.getString(0);
}
cursor.close();
cursor = null;
return contactName;
}
Try
Uri uri;
String[] projection;
Uri baseUri = Contacts.Phones.CONTENT_FILTER_URL;
projection = new String[] { android.provider.Contacts.People.NAME };
try {
Class<?> c = Class.forName("android.provider.ContactsContract$PhoneLookup");
baseUri = (Uri) c.getField("CONTENT_FILTER_URI").get(baseUri);
projection = new String[] { "display_name" };
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (SecurityException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (NoSuchFieldException e) {
e.printStackTrace();
}
uri = Uri.withAppendedPath(baseUri, Uri.encode(Uri
.encode(phoneNumber)));
Cursor cursor =mContext.getContentResolver().query(uri,
projection, null, null, null) ;
String fromDisplayName = null;
if (cursor != null) {
if (cursor.moveToFirst()){
fromDisplayName = cursor.getString(0);
}
else{
fromDisplayName="";
}
cursor.close();
} else {
fromDisplayName="";
}
return fromDisplayName;
The Uri android.provider.Contacts.People.NAME is deprecated. But android.provider.ContactsContract$PhoneLookup is available from API level 5 only. Hence it is better to use reflections to support all phones.
I'm having trouble loading a photo for a contact in Android. I've googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo?
So, given a contactUri which comes from an Activity result called using
startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST)
is:
content://com.android.contacts/data/1557
The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to:
content://com.android.contacts/contacts/1557
See the comments inline in the code below.
class ContactAccessor {
/**
* Retrieves the contact information.
*/
public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) {
//contactUri --> content://com.android.contacts/data/1557
ContactInfo contactInfo = new ContactInfo();
// Load the display name for the specified person
Cursor cursor = contentResolver.query(contactUri,
new String[]{Contacts._ID,
Contacts.DISPLAY_NAME,
Phone.NUMBER,
Contacts.PHOTO_ID}, null, null, null);
try {
if (cursor.moveToFirst()) {
contactInfo.setId(cursor.getLong(0));
contactInfo.setDisplayName(cursor.getString(1));
contactInfo.setPhoneNumber(cursor.getString(2));
}
} finally {
cursor.close();
}
return contactInfo; // <-- returns info for contact
}
public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) {
Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
// contactPhotoUri --> content://com.android.contacts/contacts/1557
InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null
Bitmap photo = BitmapFactory.decodeStream(photoDataStream);
return photo;
}
public class ContactInfo {
private long id;
private String displayName;
private String phoneNumber;
private Uri photoUri;
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
public String getDisplayName() {
return displayName;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getPhoneNumber() {
return phoneNumber;
}
public Uri getPhotoUri() {
return this.photoUri;
}
public void setPhotoUri(Uri photoUri) {
this.photoUri = photoUri;
}
public long getId() {
return this.id;
}
public void setId(long id) {
this.id = id;
}
}
}
Clearly, I'm doing something wrong here, but I can't seem to figure out what the problem is. Thanks.
This works for me:
public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}
Having scanned the many questions and answers to the problem of displaying a thumbnail I thought I would post my solution to this particular conundrum as I could only find a couple that worked at all and none that provided a good canned solution for the lazy developer.
The class below takes a Context, QuickContactBadge and a telephone number and will attach a locally stored image to the badge if there is one available for the specified phone number.
Here's the class:
public final class QuickContactHelper {
private static final String[] PHOTO_ID_PROJECTION = new String[] {
ContactsContract.Contacts.PHOTO_ID
};
private static final String[] PHOTO_BITMAP_PROJECTION = new String[] {
ContactsContract.CommonDataKinds.Photo.PHOTO
};
private final QuickContactBadge badge;
private final String phoneNumber;
private final ContentResolver contentResolver;
public QuickContactHelper(final Context context, final QuickContactBadge badge, final String phoneNumber) {
this.badge = badge;
this.phoneNumber = phoneNumber;
contentResolver = context.getContentResolver();
}
public void addThumbnail() {
final Integer thumbnailId = fetchThumbnailId();
if (thumbnailId != null) {
final Bitmap thumbnail = fetchThumbnail(thumbnailId);
if (thumbnail != null) {
badge.setImageBitmap(thumbnail);
}
}
}
private Integer fetchThumbnailId() {
final Uri uri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
final Cursor cursor = contentResolver.query(uri, PHOTO_ID_PROJECTION, null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
try {
Integer thumbnailId = null;
if (cursor.moveToFirst()) {
thumbnailId = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
}
return thumbnailId;
}
finally {
cursor.close();
}
}
final Bitmap fetchThumbnail(final int thumbnailId) {
final Uri uri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, thumbnailId);
final Cursor cursor = contentResolver.query(uri, PHOTO_BITMAP_PROJECTION, null, null, null);
try {
Bitmap thumbnail = null;
if (cursor.moveToFirst()) {
final byte[] thumbnailBytes = cursor.getBlob(0);
if (thumbnailBytes != null) {
thumbnail = BitmapFactory.decodeByteArray(thumbnailBytes, 0, thumbnailBytes.length);
}
}
return thumbnail;
}
finally {
cursor.close();
}
}
}
And here's a typical use case inside an activity:
String phoneNumber = "...";
QuickContactBadge badge = (QuickContactBadge) view.findViewById(R.id.friend);
new QuickContactHelper(this, badge, phoneNumber).addThumbnail();
In a fragment it will be slightly different:
String phoneNumber = "...";
QuickContactBadge badge = (QuickContactBadge) view.findViewById(R.id.friend);
new QuickContactHelper(getActivity(), badge, phoneNumber).addThumbnail();
Now there are ways to be more efficient - for example if you are rendering a message timeline you'd want to re-use the same bitmap object for every badge instance for a given phone number instead of constantly creating new helper class instances and re-retrieving the bitmap - but my purpose here was to post a solution that is stripped down to the absolute minimum for clarity whilst at the same time providing a complete and usable solution out of the box. This solution has been built and tested on Andriod 4.0, and tested on 4.1 as well.
After a lot of debugging nights I discover that the best approach is to use the contact id and if it fails to use the photo id.
public static Bitmap loadContactPhoto(ContentResolver cr, long id,long photo_id)
{
Uri uri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(cr, uri);
if (input != null)
{
return BitmapFactory.decodeStream(input);
}
else
{
Log.d("PHOTO","first try failed to load photo");
}
byte[] photoBytes = null;
Uri photoUri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, photo_id);
Cursor c = cr.query(photoUri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null);
try
{
if (c.moveToFirst())
photoBytes = c.getBlob(0);
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
} finally {
c.close();
}
if (photoBytes != null)
return BitmapFactory.decodeByteArray(photoBytes,0,photoBytes.length);
else
Log.d("PHOTO","second try also failed");
return null;
}
the code tested on emulator and Nexus S device and seems to work.
Guys, I spent many hours attempting to figure this out. Here is a method I created that will get you your facebook photo by phone number (no dashes). You can, of course, modify it accordingly:
public Bitmap getFacebookPhoto(String phoneNumber) {
Uri phoneUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Uri photoUri = null;
ContentResolver cr = this.getContentResolver();
Cursor contact = cr.query(phoneUri,
new String[] { ContactsContract.Contacts._ID }, null, null, null);
if (contact.moveToFirst()) {
long userId = contact.getLong(contact.getColumnIndex(ContactsContract.Contacts._ID));
photoUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, userId);
}
else {
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}
if (photoUri != null) {
InputStream input = ContactsContract.Contacts.openContactPhotoInputStream(
cr, photoUri);
if (input != null) {
return BitmapFactory.decodeStream(input);
}
} else {
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}
Bitmap defaultPhoto = BitmapFactory.decodeResource(getResources(), android.R.drawable.ic_menu_report_image);
return defaultPhoto;
}
None of these approaches worked for me. What did work was:
String[] projection = new String[] {
ContactsContract.Contacts.PHOTO_ID, ///< the correct ID for photo retrieval in loadLocalContactPhotoBytes()
// ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
// ContactsContract.CommonDataKinds.Photo.PHOTO
};
ContentResolver cr = ctx.getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
// Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
// new String[] {RawContacts._ID, RawContacts.ACCOUNT_TYPE, RawContacts.ACCOUNT_NAME},
// new String[] {Contacts._ID},
projection, null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
....
//the 'cursor' above got passed as an argument below
private byte[] loadLocalContactPhotoBytes(ContentResolver cr, Cursor cursor, byte[] defaultPhotoBytes)
{
byte[] photoBytes = null;// = cursor.getBlob(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Photo.PHOTO));
// int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts._ID));
int id = cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
// Uri contactUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id);
// Uri photoUri = Uri.withAppendedPath(contactUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Uri photoUri = ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, id);
Cursor c = cr.query(photoUri, new String[] {ContactsContract.CommonDataKinds.Photo.PHOTO}, null, null, null);
try
{
if (c.moveToFirst())
photoBytes = c.getBlob(0);
} catch (Exception e) {
// TODO: handle exception
Log.w(_TAG, e.toString());
} finally {
c.close();
}
photoBytes = photoBytes == null ? defaultPhotoBytes : photoBytes;
return photoBytes;
}
Just for kicks I copied most of the answers here into a single class to see if any of them would succeed in getting the Facebook thumbnail. They didn't.... But, here is what I did to perhaps save you doing the same.
It shows the results in a dialog for ease.
Please be aware - it's not optimised and you'll need to catch errors and close cursors etc:
To start the contact picker intent:
private static final int SELECT_CONTACT = 1468;
Intent contactPickerIntent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
contactPickerIntent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
try {
startActivityForResult(contactPickerIntent, SELECT_CONTACT);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
The callback:
#Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (data != null && resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case SELECT_CONTACT:
Uri contactURI = data.getData();
if (contactURI != null) {
String contactID = data.getData().getLastPathSegment().trim();
String contactName = ContactThumb.getDisplayName(getActivity(), contactURI);
if (contactName != null && !contactName.isEmpty() && contactID != null && !contactID.isEmpty()) {
final int THUMBNAIL_SIZE = 100;
Bitmap contactThumb = ContactThumb.loadContactPhoto(getActivity(), Long.valueOf(contactID));
if (contactThumb != null) {
final AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
final int width = contactThumb.getWidth();
final int height = contactThumb.getHeight();
final int ratio = width / height;
final Bitmap resized = ThumbnailUtils.extractThumbnail(contactThumb, (THUMBNAIL_SIZE * ratio),
THUMBNAIL_SIZE);
Drawable icon = new BitmapDrawable(getActivity().getResources(), resized);
alert.setIcon(icon);
alert.setTitle("Contact details");
final TextView homeTV = new TextView(getActivity());
homeTV.setText(contactName + " : " + contactID);
homeTV.setTextSize(12);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
homeTV.setTextColor(Color.WHITE);
}
homeTV.setPadding(30, 2, 20, 10);
homeTV.setMovementMethod(LinkMovementMethod.getInstance());
alert.setView(homeTV);
alert.show();
} else {
Toast.makeText(getActivity(), "Photo null", Toast.LENGTH_SHORT).show();
}
}
}
break;
}
} else {
// cancelled or error
}
}

Good luck
It seems that my problem was because the contacts in my device were synced from facebook, and the photo therefore is not available.
http://groups.google.com/group/android-developers/msg/be8d0cf3928e4b7f
Android documentation says, that we should do it in this way.
public Bitmap openPhoto(long contactId) {
Uri contactUri = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, contactId);
Uri photoUri = Uri.withAppendedPath(contactUri, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Cursor cursor = getContentResolver().query(photoUri,
new String[] {ContactsContract.Contacts.Photo.PHOTO}, null, null, null);
if (cursor == null) {
return null;
}
try {
if (cursor.moveToFirst()) {
byte[] data = cursor.getBlob(0);
if (data != null) {
return BitmapFactory.decodeStream(new ByteArrayInputStream(data));
}
}
} finally {
cursor.close();
}
return null;
}
contactId stands for:
getString(c.getColumnIndex(ContactsContract.Contacts._ID))
source: https://developer.android.com/reference/android/provider/ContactsContract.Contacts.Photo.html
After some research I found the solution at: Displaying the Quick Contact Badge
My code with some minor modifications, works fine for me
public Bitmap loadContactPhoto(String name) {
String photoUri = null;
int thumbnailColumn;
ContentResolver cr = GlobalData.instance().getContext().getContentResolver();
String[] projection = new String[] { ContactsContract.Contacts._ID ,ContactsContract.Contacts.PHOTO_ID, ContactsContract.Contacts.PHOTO_URI, ContactsContract.Contacts.PHOTO_THUMBNAIL_URI};
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, projection, ContactsContract.Contacts.DISPLAY_NAME + "='" + name + "'", null, null);
if (cursor.moveToFirst()) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
thumbnailColumn = cursor.getColumnIndex(Contacts.PHOTO_THUMBNAIL_URI);
else
thumbnailColumn = cursor.getColumnIndex(PhoneLookup._ID);
photoUri = cursor.getString(thumbnailColumn);
if(photoUri != null)
return loadContactPhotoThumbnail(photoUri);
else
return null;
}
return null;
}
private Bitmap loadContactPhotoThumbnail(String photoData) {
AssetFileDescriptor afd = null;
try {
Uri thumbUri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
thumbUri = Uri.parse(photoData);
} else {
final Uri contactUri = Uri.withAppendedPath(Contacts.CONTENT_URI, photoData);
thumbUri = Uri.withAppendedPath(contactUri, Photo.CONTENT_DIRECTORY);
}
afd = GlobalData.instance().getContext().getContentResolver().openAssetFileDescriptor(thumbUri, "r");
FileDescriptor fileDescriptor = afd.getFileDescriptor();
if (fileDescriptor != null)
return BitmapFactory.decodeFileDescriptor(fileDescriptor, null, null);
} catch (FileNotFoundException e) {
} finally {
if (afd != null) {
try {
afd.close();
} catch (IOException e) {
}
}
}
return null;
