我正在使用 TelecomManager、ConnectionService 和 Connection 构建基本的呼叫应用程序。但是，当有来电时，我的incomingActivity UI 没有显示。以下是到目前为止的示例代码。

在我的 MainActivity.java

Intent intent = new Intent(TelecomManager.ACTION_CHANGE_DEFAULT_DIALER);
intent.putExtra(TelecomManager.EXTRA_CHANGE_DEFAULT_DIALER_PACKAGE_NAME, getPackageName());

startActivity(intent);

// ================================================================
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    TelecomManager manager = (TelecomManager) getSystemService(TELECOM_SERVICE);

//            new ComponentName(getPackageName(), CallHandler.TAG), "myCallHandlerId");
    PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(
            new ComponentName(getApplicationContext(), CallHandler.TAG), "myCallHandlerId");

    PhoneAccount phoneAccount = PhoneAccount
                            .builder(phoneAccountHandle, "myCallHandlerId")
                            .setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED)
                            .build();

    manager.registerPhoneAccount(phoneAccount);

    Log.i("Phone Account", "" + manager.getPhoneAccount(phoneAccountHandle));
    Log.i("Phone Account", "" + manager.getPhoneAccount(phoneAccountHandle).isEnabled());
    Log.i("Phone Account", "" + manager.getPhoneAccount(phoneAccountHandle).getClass());

    Log.i("Phone Account isEnabled", "" + phoneAccount.isEnabled());

    Bundle bundle = new Bundle();

    Uri uri …

我想为 Voip 拨号器应用程序实现“android.telephony”库。因此，根据此https://developer.android.com/reference/android/telecom/ConnectionService我正在尝试注册 PhoneAccount。我正在做如下，

private void registerPhoneAcc(String calleeURI, String phoneNumber) {
       
        TelecomManager telecomManager = null;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
            telecomManager = (TelecomManager) getContext().getSystemService(Context.TELECOM_SERVICE);
        }
        ComponentName componentName = new ComponentName(getContext().getPackageName(), String.valueOf(MyConnectionService.class));
        PhoneAccountHandle phoneAccountHandle = null;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
            phoneAccountHandle = new PhoneAccountHandle(componentName,"App" );
            PhoneAccount phoneAccount = PhoneAccount.builder(phoneAccountHandle, "Primary").setCapabilities(PhoneAccount.CAPABILITY_CALL_PROVIDER).build();
            telecomManager.registerPhoneAccount(phoneAccount);
        }
       
    }

<service android:name=".app.MyConnectionService"
            android:permission="android.permission.BIND_TELECOM_CONNECTION_SERVICE">
            <intent-filter>
                <action android:name="android.telecom.ConnectionService" />
            </intent-filter>
        </service>

尽管我已经包含了许可，但我遇到了以下异常

W/System.err: java.lang.SecurityException: PhoneAccount connection service requires BIND_TELECOM_CONNECTION_SERVICE permission.

我需要拦截设备框架发出的传出呼叫的事件。
按照android 指南，我停在第 3 点电信子系统绑定到您的应用程序的 ConnectionService 实现。，也就是说我已经走到了这一步：

通话流程

val telecomManager :TelecomManager= getSystemService(
        TELECOM_SERVICE
    ) as TelecomManager
    if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(this, arrayOf(Manifest.permission.CALL_PHONE),
            2333)
    } else {
        try {
            val phoneAccountHandle = PhoneAccountHandle(ComponentName(
                applicationContext,
                MyConnectionService::class.java
            ), "ID999")
            telecomManager.registerPhoneAccount(PhoneAccount.builder(
                phoneAccountHandle,
                "label"
            ).setCapabilities(PhoneAccount.CAPABILITY_CONNECTION_MANAGER) .build())
            val extras = Bundle()
            extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandle)
            telecomManager.placeCall(Uri.parse("tel:$phoneNumber"), extras)
        } catch (e: SecurityException) {
            e.printStackTrace()
        }
    }

连接服务

class MyConnectionService : ConnectionService() {
private val TAG = "mycnnser"
override fun onCreate() {
    super.onCreate()
    Log.d(TAG, …
