如何修复 java.lang.SecurityException: This PhoneAccountHandle is not enabled for this user?

如何解决如何修复 java.lang.SecurityException: This PhoneAccountHandle is not enabled for this user?

我使用下面给出的代码来制作自我管理的连接服务。但这已因此错误而停止工作：

java.lang.SecurityException：此用户未启用此 PhoneAccountHandle！

代码：

class CallManager(context: Context) {
val telecomManager: TelecomManager
var phoneAccountHandle: PhoneAccountHandle
var context: Context

init {
    telecomManager = context.getSystemService(Context.TELECOM_SERVICE) as TelecomManager
    this.context = context

    val componentName = ComponentName(this.context,ConnService::class.java)
    phoneAccountHandle = PhoneAccountHandle(componentName,"com.darkhorse.videocalltest")
}

fun register(){
    val phoneAccount = PhoneAccount.builder(phoneAccountHandle,"com.darkhorse.videocalltest")
        .setCapabilities(PhoneAccount.CAPABILITY_CALL_PROVIDER) .setCapabilities(PhoneAccount.CAPABILITY_CONNECTION_MANAGER).build()
    telecomManager.registerPhoneAccount(phoneAccount)
}

fun incomingCall(caller: String?){
    val callInfo = Bundle()
    callInfo.putString("from",caller)
    telecomManager.addNewIncomingCall(phoneAccountHandle,callInfo)
    Log.i("incomingCall","incomingCall")
}
}

我确信之前的代码运行良好。
