运行 Android 10 或更高版本的设备与运行 Android 9 或更低版本的设备处理通话 Intent 的方式不同。在 Android 10 及更高版本上,ACTION_NEW_OUTGOING_CALL
广播已弃用,并由 CallRedirectionService
API 取代。CallRedirectionService
提供了接口,供您用于修改 Android 平台发起的拨出电话。例如,第三方应用可以取消通话并将其通过 VoIP 重新路由。
Kotlin
class RedirectionService : CallRedirectionService() { override fun onPlaceCall( handle: Uri, initialPhoneAccount: PhoneAccountHandle, allowInteractiveResponse: Boolean ) { // Determine if the call should proceed, be redirected, or cancelled. val callShouldProceed = true val callShouldRedirect = false when { callShouldProceed -> { placeCallUnmodified() } callShouldRedirect -> { // Update the URI to point to a different phone number or modify the // PhoneAccountHandle and redirect. redirectCall(handle, initialPhoneAccount, true) } else -> { cancelCall() } } } }
Java
class RedirectionService extends CallRedirectionService { @Override public void onPlaceCall( @NonNull Uri handle, @NonNull PhoneAccountHandle initialPhoneAccount, boolean allowInteractiveResponse ) { // Determine if the call should proceed, be redirected, or cancelled. // Your app should implement this logic to determine the redirection. boolean callShouldProceed = true; boolean callShouldRedirect = false; if (callShouldProceed) { placeCallUnmodified(); } else if (callShouldRedirect) { // Update the URI to point to a different phone number or modify the // PhoneAccountHandle and redirect. redirectCall(handle, initialPhoneAccount, true); } else { cancelCall(); } } }
您必须在清单中注册此服务,系统才能正确启动它。
<service
android:name=".RedirectionService"
android:permission="android.permission.BIND_CALL_REDIRECTION_SERVICE">
<intent-filter>
<action android:name="android.telecom.CallRedirectionService"/>
</intent-filter>
</service>
要使用重定向服务,您的应用必须从 RoleManager
请求通话重定向角色。这将询问用户是否允许您的应用处理通话重定向。如果您的应用未获得此角色,则不会使用您的重定向服务。
当用户启动您的应用时,您应检查您的应用是否拥有此角色,以便根据需要请求该角色。您会启动由 RoleManager
创建的 Intent,因此请务必替换 onActivityResult()
函数来处理用户的选择。
Kotlin
class MainActivity : AppCompatActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.activity_main) // Tell the system that you want your app to handle call redirects. This // is done by using the RoleManager to register your app to handle redirects. if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) { val roleManager = getSystemService(Context.ROLE_SERVICE) as RoleManager // Check if the app needs to register call redirection role. val shouldRequestRole = roleManager.isRoleAvailable(RoleManager.ROLE_CALL_REDIRECTION) && !roleManager.isRoleHeld(RoleManager.ROLE_CALL_REDIRECTION) if (shouldRequestRole) { val intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_REDIRECTION) startActivityForResult(intent, REDIRECT_ROLE_REQUEST_CODE) } } } companion object { private const val REDIRECT_ROLE_REQUEST_CODE = 1 } }
Java
class MainActivity extends AppCompatActivity { private static final int REDIRECT_ROLE_REQUEST_CODE = 0; @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Tell the system that you want your app to handle call redirects. This // is done by using the RoleManager to register your app to handle redirects. if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) { RoleManager roleManager = (RoleManager) getSystemService(Context.ROLE_SERVICE); // Check if the app needs to register call redirection role. boolean shouldRequestRole = roleManager.isRoleAvailable(RoleManager.ROLE_CALL_REDIRECTION) && !roleManager.isRoleHeld(RoleManager.ROLE_CALL_REDIRECTION); if (shouldRequestRole) { Intent intent = roleManager.createRequestRoleIntent(RoleManager.ROLE_CALL_REDIRECTION); startActivityForResult(intent, REDIRECT_ROLE_REQUEST_CODE); } } } }
