I want to export the Phone contacts to External storage area. I didn't work with this type of method. Anyone guide me to do this?
In your code, you wrote one function but from where is this function called? And what is the meaning of get(View view) function? This function is not being called so it can be removed.
I've edited my answer as per your requirements and tested it with 500 Contacts to save a single vCard file with 500 contacts in my sd card.

Android Nougat Update :
Other answers code working for lots of people before Nougat update.
Please take care of :
byte[] buf = new byte[(int) fd.getDeclaredLength()];
is not working on Android Nougat.
fd.getDeclaredLength() is always return -1.
Please use below code for read bytes without any library :
byte[] buf = readBytes(fis);
public byte[] readBytes(InputStream inputStream) throws IOException {
// this dynamically extends to take the bytes you read
ByteArrayOutputStream byteBuffer = new ByteArrayOutputStream();
// this is storage overwritten on each iteration with bytes
int bufferSize = 1024;
byte[] buffer = new byte[bufferSize];
// we need to know how may bytes were read to write them to the byteBuffer
int len = 0;
while ((len = inputStream.read(buffer)) != -1) {
byteBuffer.write(buffer, 0, len);
}
// and then we can return your byte array.
return byteBuffer.toByteArray();
}
The method readBytes() get from this answer.
Try out this. its work for me to create a .vcf file of all contact and stored it into SDCARD.
make sure all permission are give properly.
public static void getVCF()
{
final String vfile = "POContactsRestore.vcf";
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null, null, null);
phones.moveToFirst();
for(int i =0;i<phones.getCount();i++)
{
String lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd;
try
{
fd = mContext.getContentResolver().openAssetFileDescriptor(uri, "r");
FileInputStream fis = fd.createInputStream();
byte[] buf = new byte[(int) fd.getDeclaredLength()];
fis.read(buf);
String VCard = new String(buf);
String path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
FileOutputStream mFileOutputStream = new FileOutputStream(path, true);
mFileOutputStream.write(VCard.toString().getBytes());
phones.moveToNext();
Log.d("Vcard", VCard);
}
catch (Exception e1)
{
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
}
I have removed the exception and other error and below is my CODE :
private final String vfile = "POContactsRestore.vcf";
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
null, null, null);
phones.moveToFirst();
String lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd;
try {
fd = this.getContentResolver().openAssetFileDescriptor(uri, "r");
FileInputStream fis = fd.createInputStream();
byte[] buf = new byte[(int) fd.getDeclaredLength()];
fis.read(buf);
String vCard = new String(buf);
String path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
FileOutputStream mFileOutputStream = new FileOutputStream(path, false);
mFileOutputStream.write(vCard.toString().getBytes());
Log.d("Vcard", vCard);
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
If you can iterate through loop and get the vCard for the contacts and store it in the SDCARD.
I tried above two codes and I got the .VCF file too, but it was containing only one contact. so here is Perfectly Edited and running code....you will get all contacts in .VCF file:
private void getVcardString() throws IOException {
// TODO Auto-generated method stub
vCard = new ArrayList<String>(); // Its global....
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
if(cursor!=null&&cursor.getCount()>0)
{
int i;
String storage_path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile;
FileOutputStream mFileOutputStream = new FileOutputStream(storage_path, false);
cursor.moveToFirst();
for(i = 0;i<cursor.getCount();i++)
{
get(cursor);
Log.d("TAG", "Contact "+(i+1)+"VcF String is"+vCard.get(i));
cursor.moveToNext();
mFileOutputStream.write(vCard.get(i).toString().getBytes());
}
mFileOutputStream.close();
cursor.close();
}
else
{
Log.d("TAG", "No Contacts in Your Phone");
}
}
Second Method:
private void get(Cursor cursor2) {
String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd;
try {
fd = this.getContentResolver().openAssetFileDescriptor(uri, "r");
FileInputStream fis = fd.createInputStream();
byte[] buf = new byte[(int) fd.getDeclaredLength()];
fis.read(buf);
String vcardstring= new String(buf);
vCard.add(vcardstring);
} catch (Exception e1)
{
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
Please Don't forget to add :
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
It's working for me and as well working in Nougat devices. Thank you so much #pratik and #sanat .

I am trying to convert my contacts to .vcf file in android but it gives an error and can not export contacts.
It gives me an error it goes in the catch block and gives:
java.lang.NegativeArraySizeException: -1

public void getVCF() {
final String vfile = "Contacts.vcf";
Cursor phones = mContext.getContentResolver().query(

null, null, null);
phones.moveToFirst();
for (int i = 0; i < phones.getCount(); i++) {

try {

In Android 7, getContentResolver().openAssetFileDescriptor(vCardUri, "r") returns AssetFileDescriptor having declaredLength as -1 returned by getDeclaredLength().
Trying to export the contacts as vcards into vcf file. The code I have tried is as follows
Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor fd = resolver.openAssetFileDescriptor(uri, "r");
FileInputStream fis = fd.createInputStream();
byte[] b = new byte[(int)fd.getDeclaredLength()];
fis.read(b);
The above code works perfectly in Android 6 or below.But when ran using Android 7, The line creating byte[] results in NegativeByteArraySizeException as the declaredLength is -1.
When I debugged downloading the sources of Android 7, I observed the problem.
Any kind of health would be really appreciable.
With the help of #pskink, I found the following solve my problem.
String lookupKey = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY));
Uri vCardUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey);
AssetFileDescriptor assetFileDescriptor;
FileInputStream inputStream;
try {
assetFileDescriptor = getActivity().getContentResolver().openAssetFileDescriptor(vCardUri, "r");
if (assetFileDescriptor != null) {
inputStream = assetFileDescriptor.createInputStream();
return readAsByteArray(inputStream);
}
} catch (FileNotFoundException e) {
Log.e(TAG, "Vcard for the contact " + lookupKey + " not found", e);
} catch (IOException e) {
Log.e(TAG, "Problem creating stream from the assetFileDescriptor.", e);
}
where the readAsByteArray() is written using the code from Mihai Snippet.
Thank you #pskink
In your code you are you are using the openAssestFileDescriptor instead use the openFileDescriptor because openAssestFileDescriptor is use to read a file in your asset folder not the file Uri

In Android Nougat :

fd.getDeclaredLength() return -1.
Check my answer here link.
replace this
AssetFileDescriptor assetFileDescriptor = activity.getContentResolver().openAssetFileDescriptor(uri, "r");

byte[] buf = new byte[(int) assetFileDescriptor.getDeclaredLength()];
with this

getDeclaredLength returns -1 if the AssetFileDescriptor is not initialized with length.
You would be better off using getStatSize() in this case.
I had the same exception, but on a real device.
