I want to save the contacts as a .vcf file. I also want to share this .vcf file I created (Gmail, etc.).
The following code works perfectly. I can see the contact list in LogCat. But I couldn't see it in any kind of device storage. I gave the user permission. But it doesn't register. I want to save and share this generated .vcf file. Any help, I'd appreciate it.
My Activity
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Share_VCF_Button = findViewById(R.id.Share_VCF_Button );
Share_VCF_Button .setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//Share .vcf file with Gmail, etc.
}
});
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.READ_CONTACTS},RequestContactPermissionID);
ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},RequestWritePermissionID);
vfile = "Contacts" + "_" + System.currentTimeMillis()+".vcf";
getVcardString();
}
private void getVcardString() {
// TODO Auto-generated method stub
vCard = new ArrayList<String>();
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
if(cursor!=null&&cursor.getCount()>0)
{
cursor.moveToFirst();
for(int i =0;i<cursor.getCount();i++){
get(cursor);
// Log.d("TAG", "Contact "+(i+1)+"VcF String is"+vCard.get(i));
cursor.moveToNext();
}
}
else
{
Log.d("TAG", "No Contacts in Your Phone");
}
}
public void get(Cursor cursor) {
//cursor.moveToFirst();
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");
// Your Complex Code and you used function without loop so how can you get all Contacts Vcard.??
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 out = new FileOutputStream(path);
out.write(VCard.toString().getBytes());
out.close();
//I can show vcf logs.
Log.d("Vcard", VCard);
} catch (Exception e1){
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
My AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
Edit;
Everything's working right now. I see the .vcf file I created in storage. But it doesn't write all the contacts to the .vcf file. I see it all on LogCat. But it does not repeat in the .vcf file. Although I can see everyone in my contact list in logcat, why can't I see it in the .vcf file?
