android - 三星设备上不调用 self 管理的连接服务回调

Question

我使用 this guide 开发了一个 VoIP 应用程序.
我在三星设备上遇到了自我管理连接服务的问题。

我正在使用 TelecomManager 调用电话。
我希望 ConnectionService::onCreateOutgoingConnection 或 ConnectionService::onCreateOutgoingConnectionFailed 将被调用，但它不会在某些三星设备上发生。

调用电话后dialog window appears .在三星 Galaxy s10 上，会出现一个带有“未发送调用”文本的 android toast。不调用连接服务的方法。

在带有 Vanilla Android 的手机上，它可以按预期工作。

有谁知道如何解决这个问题？

            </intent-filter>
        </service>

    </application>

</manifest>

连接服务:

public class ConnectionService extends android.telecom.ConnectionService {
    private static final String TAG = "ConnectionService";
    @Override
    public android.telecom.Connection onCreateIncomingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
        Log.i(TAG, "onCreateIncomingConnection");
        Connection connection = new Connection();
        MainActivity.setConnection(connection);
        return connection;
    }

    @Override
    public void onCreateIncomingConnectionFailed(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
        Log.i(TAG, "onCreateIncomingConnectionFailed");
        super.onCreateIncomingConnectionFailed(connectionManagerPhoneAccount, request);
    }

    @Override
    public android.telecom.Connection onCreateOutgoingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
        Log.i(TAG, "onCreateOutgoingConnection");
        Connection connection = new Connection();
        MainActivity.setConnection(connection);
        return connection;
    }

    @Override
    public void onCreateOutgoingConnectionFailed(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
        Log.i(TAG, "onCreateOutgoingConnectionFailed");
        super.onCreateOutgoingConnectionFailed(connectionManagerPhoneAccount, request);
    }
}

联系:

public class Connection extends android.telecom.Connection {
    private static final String TAG = "Connection";

    public Connection() {
        super();
        setConnectionProperties(android.telecom.Connection.PROPERTY_SELF_MANAGED);
    }

    @Override
    public void onStateChanged(int state) {
        super.onStateChanged(state);
        Log.i(TAG, "onStateChanged state=" + android.telecom.Connection.stateToString(state));
    }
}

电话帐户创建:

    void createAccount() {
        tm = (TelecomManager) getSystemService(Context.TELECOM_SERVICE);
        if (tm == null) {
            throw new RuntimeException("cannot obtain telecom system service");
        }

        ComponentName connectionServiceName = new ComponentName(getApplicationContext(), ConnectionService.class);
        PhoneAccountHandle accountHandle = new PhoneAccountHandle(connectionServiceName, PHONE_ACCOUNT_LABEL);
        try {
            PhoneAccount phoneAccount = tm.getPhoneAccount(accountHandle);
            if (phoneAccount == null) {
                PhoneAccount.Builder builder = PhoneAccount.builder(accountHandle, PHONE_ACCOUNT_LABEL);
                builder.setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED);
                phoneAccount = builder.build();
                tm.registerPhoneAccount(phoneAccount);
            }
            this.accountHandle = phoneAccount.getAccountHandle();

            if (tm.getPhoneAccount(accountHandle) == null) {
                throw new RuntimeException("cannot create account");
            }

        } catch (SecurityException e) {
            throw new RuntimeException("cannot create account", e);
        }
    }

调用创建:

    void createCall() {
        try {
            Bundle extras = new Bundle();
            extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, accountHandle);
            Uri uri = Uri.fromParts(PhoneAccount.SCHEME_SIP, "test_call", null);
            tm.placeCall(uri, extras);
        }
        catch (SecurityException e) {
            throw new RuntimeException("cannot place call", e);
        }
    }

一些固件更新后，上面的代码开始正常工作。
所以，问题出在手机本身。
