问题描述
更新：
感谢 Vadik 的帮助，我更新了 Main 和 CallService。
我现在收到以下错误：
java.lang.RuntimeException：无法实例化服务
com.test.phonecall.CallService:
java.lang.illegalaccessexception:
java.lang.class
我在使用 Telecom 实施自我管理的电话呼叫方法时遇到了困难（如下面的链接所示） https://developer.android.com/guide/topics/connectivity/telecom/selfManaged#connection-service
https://github.com/dmalukov/TComTest/tree/master/app/src/main/java/com/example/tcomtest
但它是用 Kotlin 编写的，我需要用 Java 实现和理解它，但我在翻译它们时遇到了一些困难。因此，如果有人可以帮助理解和实施它，那就太好了！
这是我目前得到的：（仅使用我“应该”需要打电话的方法）
TComManager：
public class TComManager{
private TelecomManager tm;
private Context context;
public TComManager(Context context) {
tm = (TelecomManager) context.getSystemService(Context.TELECOM_SERVICE);
this.context = context;
}
public Boolean registeraccount(){
PhoneAccountHandle accountHandle = getAccountHandle();
PhoneAccount phoneAccount = tm.getPhoneAccount(accountHandle);
if (phoneAccount == null) {
PhoneAccount.Builder builder = PhoneAccount.builder(accountHandle,BuildConfig.APPLICATION_ID);
builder.setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED);
phoneAccount = builder.build();
tm.registerPhoneAccount(phoneAccount);
}
return true;
}
private PhoneAccountHandle getAccountHandle() {
String phoneAccountLabel = BuildConfig.APPLICATION_ID;
ComponentName componentName = new ComponentName(context,TComService.class);
return new PhoneAccountHandle(componentName,phoneAccountLabel);
}
public void addOutgoingCall() {
Bundle extras = new Bundle();
extras.putParcelable(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE,getAccountHandle());
tm.placeCall(Uri.parse("tel:123456"),extras);
}
}
TComService：
public class TComService extends ConnectionService {
@Override
public void onCreateOutgoingConnectionFailed(PhoneAccountHandle connectionManagerPhoneAccount,ConnectionRequest request) {
System.out.println("onCreateOutgoingConnectionFailed");
}
@Override
public Connection onCreateOutgoingConnection(PhoneAccountHandle handle,ConnectionRequest request){
System.out.println("onCreateOutgoingConnection - handle="+handle+",request="+request);
TComConnection connection = new TComConnection();
bindService(new Intent(getApplicationContext(),CallService.class),new CallServiceConnection(connection),0);
return connection;
}
private class CallServiceConnection implements ServiceConnection {
private TComConnection tcomConnection;
public CallServiceConnection(TComConnection tcomConnection) {
this.tcomConnection=tcomConnection;
}
@Override
public void onServiceConnected(ComponentName name,IBinder binder) {
System.out.println("Service Connected");
CallService.CallServiceBinder callSrvBinder = (CallService.CallServiceBinder)binder;
callSrvBinder.getCallService().addConnection(tcomConnection);
unbindService(this);
}
@Override
public void onServicedisconnected(ComponentName name) {
System.out.println("Service disconnected");
}
}
}
TComConnection：
public class TComConnection extends Connection {
private int listener;
public TComConnection(){
setConnectionProperties(Connection.PROPERTY_SELF_MANAGED);
}
public int getListener() {
return this.listener;
}
public void setListener(int l) {
this.listener = l;
}
@Override
public void onStateChanged(int state) {
super.onStateChanged(state);
System.out.println("onStateChanged,state="+state);
listener=state;
}
@Override
public void onReject() {
System.out.println("onReject");
close();
}
@Override
public void ondisconnect() {
System.out.println("ondisconnect");
close();
}
private void close() {
setdisconnected(new disconnectCause(disconnectCause.CANCELED));
destroy();
}
public Boolean isClosed() {
return this.getState() == STATE_disCONNECTED;
}
}
呼叫服务：
class CallService extends Service{
Function<ASSComConnection,Void> connectionListener = connection -> null;
@Override
public IBinder onBind(Intent intent){
return new CallServiceBinder();
}
public void addConnection(ASSComConnection newConnection) {
connectionListener = new Function<ASSComConnection,Void>() {
@Override
public Void apply(ASSComConnection assComConnection) {
assComConnection = newConnection;
return null;
}
};
}
public class CallServiceBinder extends Binder {
public CallService getCallService() {
return CallService.this;
}
}
}
主要内容：
public class hello extends Activity
{
private ServiceConnection serviceConnection = new CallServiceConnection();
private TComConnection connection = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TComManager tcomManager = new TComManager(this);
try {
if (tcomManager.registeraccount()) {
tcomManager.addOutgoingCall();
} else {
System.out.println("*****Error: "+"account isn't registered");
}
} catch (Exception e) {
System.out.println("*****Error: "+e.getMessage());
}
}
@Override
public void onStart() {
super.onStart();
bindService(new Intent(this,serviceConnection,Context.BIND_AUTO_CREATE);
}
@Override
public void onStop() {
super.onStop();
closeConnection();
unbindService(serviceConnection);
}
private void closeConnection() {
if (!connection.isClosed()) {
connection.setdisconnected(new disconnectCause(disconnectCause.CANCELED));
}
}
private void addConnection(TComConnection newConnection) {
connection = newConnection;
}
public class CallServiceConnection implements ServiceConnection {
private CallService callService = null;
@Override
public void onServiceConnected(ComponentName name,IBinder binder) {
CallService.CallServiceBinder callSrvBinder = (CallService.CallServiceBinder)binder;
CallService service = callSrvBinder.getCallService();
service.connectionListener = connection -> {
addConnection(connection);
return null;
};
callService = service;
}
@Override
public void onServicedisconnected(ComponentName name) {
callService.addConnection(null);
}
}
}
P.S：这又是一个自我管理的电话，所以没有 startActivity(intent)
解决方法
要修复由 Unable to instantiate service 引起的 Service is not accessible from ActivityThread，只需将您的服务类设为 public：
public class CallService extends Service {
...
}
与 Java 不同，Kotlin 的所有类默认都是公开的。
