How to start a Viber call from an Android application [new version]?

Some time ago I created this post, and my colleague and I found two different answers to it (both of them worked):

  • The first solution was to use

    Intent callIntent = new Intention ("android.intent.action.CALL_PRIVILEGED");

    which will open a new window offer for a call made by all possible ways of placing a call - in this particular case they were Dialer and Viber and Skype (or any other method added later).

  • The second solution was to explicitly call Viber and put a telephone number, which would also be called

    Intent viberCallIntent = new Intent ("com.viber.voip.action.CALL"); viberCallIntent.setType ("vnd.android.cursor.item / vnd.com.viber.voip.call"); viberCallIntent.setData (Uri.parse ("tel:" + dialNumber)); viberCallIntent.putExtra ("external_call", true); viberCallIntent.putExtra ("contact_id", -1L); startActivity (viberCallIntent);

Since the last Viber update (we noticed this yesterday), none of these methods have worked. At first, you simply make a Skype call without even offering Dialer (!?!), But if Skype is not installed, it will return to Dialer and place the call. Secondly, a crash stating that there is no activity to work with Intent?

Any idea what is going on and how can this be solved?

The error log is as follows:

[UPDATE] This also indicates an error:

According to the Viber manifest, there is activity "com.viber.voip.phone.PhoneActivity", which is responsible for the action "com.viber.voip.action.CALL". In the new version of Viber (4.2.1.1) this activity is marked by android: exported = "false" . As a result of this, it is impossible to start this activity from external applications ...

Edit

This code opens the welcome screen for the specified contact.

 String sphone = "12345678"; Uri uri = Uri.parse("tel:" + Uri.encode(sphone)); Intent intent = new Intent("android.intent.action.VIEW"); intent.setClassName("com.viber.voip", "com.viber.voip.WelcomeActivity"); intent.setData(uri); context.startActivity(intent);

but the user must click the “free call” button to start the call.

You can call per Viber direct (without WelcomeActivity), but the user must have this number in Contacts.

 public void callToViberContact(String phoneNumber, Context context) { Uri uri = getUriFromPhoneNumber(phoneNumber, context); if (uri != null) { Intent intent = new Intent("android.intent.action.VIEW"); intent.setClassName("com.viber.voip", "com.viber.voip.SystemDialogActivityPublic"); intent.setData(uri); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); } else { Toast.makeText(context, "Number is not in Viber Contacts List", Toast.LENGTH_LONG).show(); } } private Uri getUriFromPhoneNumber(String phoneNumber, Context context) { Uri uri = null; String contactId = getContactIdByPhoneNumber(phoneNumber, context); if (!TextUtils.isEmpty(contactId)) { Cursor cursor = context.getContentResolver().query( ContactsContract.Data.CONTENT_URI, new String[]{ContactsContract.Data._ID}, ContactsContract.Data.DATA2 + "=? AND " + ContactsContract.Data.CONTACT_ID + " = ?", new String[]{"Viber", contactId}, null); if (cursor != null) { while (cursor.moveToNext()){ String id = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Data._ID)); if (!TextUtils.isEmpty(id)) { uri = Uri.parse(ContactsContract.Data.CONTENT_URI + "/" + id); break; } } cursor.close(); } } return uri; } private String getContactIdByPhoneNumber(String phoneNumber, Context context) { ContentResolver contentResolver = context.getContentResolver(); String contactId = null; Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber)); String[] projection = new String[]{ContactsContract.PhoneLookup._ID}; Cursor cursor = contentResolver.query( uri, projection, null, null, null); if (cursor != null) { while (cursor.moveToNext()) { contactId = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.PhoneLookup._ID)); } cursor.close(); } return contactId; }

READ_CONTACTS permission required. Remember to add to the manifest:

 <uses-permission android:name="android.permission.READ_CONTACTS" />
