不久前我创建了this帖子，我的同事和我找到了两个不同的答案（两个都有效）：
第一个解决方案是使用
Intent callIntent = new 意图（ “android.intent.action.CALL_PRIVILEGED”）;
这将打开新窗口，提供所有人的通话 可能的拨打电话的方式 - 在这种特殊情况下，他们是 拨号器和Viber以及Skype（或稍后添加的任何其他方法）。
第二个解决方案是明确调用Viber并拨打电话 要调用的号码
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）;
自上次Viber更新（我们昨天注意到）以来，这些方法都不起作用。第一个只是使用Skype打电话，甚至不提供拨号器（！？！），但如果没有安装Skype，那么它将回落到拨号器并拨打电话。第二个崩溃声称没有找到处理Intent的Activity？
知道发生了什么以及如何解决这个问题？
错误日志如下：

[UPDATE] 这也显示为错误：
01-27 19:46:56.704: D/Greska(19822): Permission Denial: starting Intent { act=com.viber.voip.action.CALL dat=tel:xxxxxxxxx cmp=com.viber.voip/com.viber.service.OutgoingCallBroadcaster (has extras) } from ProcessRecord{416c41b8 19822:rs.limitline.maxitaxins/u0a10065} (pid=19822, uid=10065) not exported from uid 10147
答案 0 :(得分：20)
根据Viber的清单，有活动“com.viber.voip.phone.PhoneActivity”负责行动“com.viber.voip.action.CALL”。在新版本的Viber（4.2.1.1）中，此活动以android:exported="false"标记。因此，再也无法从外部应用程序启动此活动......
修改
此代码打开指定联系人的欢迎屏幕
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);
但用户应点击“免费通话”按钮开始通话。
答案 1 :(得分：4)
可以直接按Viber进行呼叫（不使用WelcomeActivity），但用户应在联系人中使用此号码。
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;
}
需要READ_CONTACTS权限。不要忘记添加Manifest：
<uses-permission android:name="android.permission.READ_CONTACTS" />
答案 2 :(得分：0)
String uriString = "content://com.android.contacts/data/" + _id;
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setData(Uri.parse(uriString));
intent.setPackage(PKG_VIBER);
startActivity(intent);
_id
