| -- README for frameworks/opt/telephony -- |
| |
| This directory contains telephony libraries which function as the |
| implementation code for APIs in TelephonyManager, SubscriptionManager, |
| SmsManager and others. |
| |
| These libraries run in the com.android.phone process and exist to support |
| telephony services created by the user’s apps (generally carrier apps), or by |
| the system. This includes making phone calls, sending SMS/MMS, and connecting |
| to data. Many APIs are plumbed down to the radio through HIDL calls defined in |
| hardware/interfaces/radio/ hardware/interfaces/radio/config and return values |
| that are sent back up as responses. |
| |
| We define several AIDL interfaces in frameworks/base/telephony/ which we |
| implement in this directory and packages/services/Telephony. This IPC scheme |
| allows us to run public API code in the calling process, while the |
| telephony-related code runs in the privileged com.android.phone process. Such |
| implementations include PhoneInterfaceManager, SubscriptionController and |
| others. |
| |
| The declaration of the com.android.phone process is in |
| packages/services/telephony and the top-level application class is PhoneApp, |
| which initializes everything else. |

| -- Testing -- |
| |
| Unit tests are found in frameworks/opt/telephony/tests and can be |
| run on a device connected through ADB with the command: |
| |
| atest FrameworksTelephonyTests |
| |
| Tests can also be run individually or by class: |
| |
| atest <testClassName |
| atest <testClassName>#<testMethodName> |
| |
| For more on atest run `atest --help` |
