Contact Ringer is an Android application that ensures important calls and SMS messages are never missed, even when your phone is in silent or vibrate mode. When a call or SMS is received from a selected contact, the ringer volume is temporarily turned on, then reverts back to the previous state after the call or message.
- Contact Selection: Choose specific contacts whose calls and SMS messages should always ring through.
- Override Silent Mode: Automatically turn on the ringer volume for selected contacts, even if the phone is in silent or vibrate mode.
- Automatic Reset: After the call or SMS, the phone's audio settings revert to the original state.
- Custom Ringtones and Volume: Set custom ringtones and volume levels for selected contacts.
- MainActivity: Handles the main interface for selecting and managing contacts.
- CallReceiver: Broadcast receiver that detects incoming calls and overrides the silent mode for selected contacts.
- SMSReceiver: Broadcast receiver that detects incoming SMS messages and overrides the silent mode for selected contacts.
- ContactsManager: Manages contact selection and retrieval from the device's contacts.
- AudioStateManager: Manages the audio state of the phone, overriding silent mode and resetting it after calls or messages.
This app requires various permissions to read contacts, call logs, and SMS, modify audio settings, and bypass battery optimizations to function.
