| Jordan Liu | da4e8b1 | 2018-09-07 18:08:24 -0700 | [diff] [blame] | 3 | This directory contains telephony libraries which function as the |
| 4 | implementation code for APIs in TelephonyManager, SubscriptionManager, |
| 5 | SmsManager and others. |

| Jordan Liu | da4e8b1 | 2018-09-07 18:08:24 -0700 | [diff] [blame] | 7 | These libraries run in the com.android.phone process and exist to support |
| 8 | telephony services created by the user’s apps (generally carrier apps), or by |
| 9 | the system. This includes making phone calls, sending SMS/MMS, and connecting |
| 10 | to data. Many APIs are plumbed down to the radio through HIDL calls defined in |
| 11 | hardware/interfaces/radio/ hardware/interfaces/radio/config and return values |
| 12 | that are sent back up as responses. |

| Jordan Liu | da4e8b1 | 2018-09-07 18:08:24 -0700 | [diff] [blame] | 14 | We define several AIDL interfaces in frameworks/base/telephony/ which we |
| 15 | implement in this directory and packages/services/Telephony. This IPC scheme |
| 16 | allows us to run public API code in the calling process, while the |
| 17 | telephony-related code runs in the privileged com.android.phone process. Such |
| Jack Yu | c97b4ba | 2023-04-14 08:36:23 -0700 | [diff] [blame] | 18 | implementations include PhoneInterfaceManager, SubscriptionManagerService and |
| Jordan Liu | da4e8b1 | 2018-09-07 18:08:24 -0700 | [diff] [blame] | 19 | others. |

| Jordan Liu | da4e8b1 | 2018-09-07 18:08:24 -0700 | [diff] [blame] | 21 | The declaration of the com.android.phone process is in |
| 22 | packages/services/telephony and the top-level application class is PhoneApp, |
| 23 | which initializes everything else. |
