I have already add 'AddPermission("android.permission.MODIFY_PHONE_STATE")' into Manifest. BUT, I still get 'java.lang.SecurityException: Neither user 10102 nor current process has android.permission.MODIFY_PHONE_STATE.'
MODIFY_PHONE_STATE
Added in API level 1
String MODIFY_PHONE_STATE
Allows modification of the telephony state - power on, mmi, etc. Does not include placing calls.
