我正在尝试实现一个基本的拨号器应用程序,该应用程序还应该处理来电。这种情况是用户将应用程序设置为默认拨号程序,然后,每个传入和传出的呼叫都应到达应用程序的ConnectionService实现中。
我不想覆盖内置的调用UI,我只需要向Connection回调添加一些额外的逻辑即可。例如,我想发送广播意向,当回答了Conention时,等等。
基于this文档,我认为我应该实现一个系统管理的ConnectionService。
我已经通过以下方式实现了ConnectionService,并且效果很好,在有呼入或呼出电话的情况下会调用回调:
public class DialerConnectionService extends ConnectionService {
NotificationManagerUtil notificationManager;
public DialerConnectionService() {
notificationManager = NotificationManagerUtil.getInstance();
}
@Override
public Connection onCreateOutgoingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
return createConnection(request, false);
}
@Override
public void onCreateOutgoingConnectionFailed(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
notificationManager.createToast(getApplicationContext(), getString(R.string.error_place_outgoing_call));
}
@Override
public Connection onCreateIncomingConnection(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
return createConnection(request, true);
}
@Override
public void onCreateIncomingConnectionFailed(PhoneAccountHandle connectionManagerPhoneAccount, ConnectionRequest request) {
notificationManager.createToast(getApplicationContext(), getString(R.string.error_create_incoming_call));
}
private TelecomConnection createConnection(ConnectionRequest request, boolean isIncoming) {
TelecomConnection connection = new TelecomConnection(getApplicationContext(), isIncoming);
connection.setConnectionProperties(Connection.PROPERTY_SELF_MANAGED);
connection.setAddress(request.getAddress(), TelecomManager.PRESENTATION_ALLOWED);
String normalizedPhoneNumber = ContactsUtil.getInstance().normalizePhoneNumberFromUri(request.getAddress());
connection.setNormalizedPhoneNumber(normalizedPhoneNumber);
connection.setCallerDisplayName(ContactsUtil.getInstance().getContactName(getApplicationContext(), normalizedPhoneNumber), TelecomManager.PRESENTATION_ALLOWED);
connection.setExtras(request.getExtras());
if (isIncoming) {
connection.setRinging();
} else {
connection.setDialing();
}
connection.setInitializing();
CallManager.getInstance().addConnection(connection);
return connection;
}
}
问题是,如果我注册了具有PhoneAccount.CAPABILITY_CONNECTION_MANAGER
功能的PhoneAccount,则由于缺少更好的单词,创建的呼叫不会变为活动状态,但是可以正确调用Connection的回调。因此,我可以发起拨出电话,但是另一部电话永远不会收到来电通知。
或者,如果我从另一部电话发起呼叫,则运行我的应用程序的设备将进入其onCreateIncomingConnection()方法,并且可以接听该呼叫,但发起方的电话仍在拨号。
我已经按照以下方式注册了PhoneAccount,但我怀疑问题出在这里:
public boolean checkAccountHandler(Context ctx) {
PhoneAccountHandle phoneAccountHandle = getPhoneAccountHandle(ctx);
telecomManager = (TelecomManager) ctx.getSystemService(Context.TELECOM_SERVICE);
PhoneAccount phoneAccount = telecomManager.getPhoneAccount(phoneAccountHandle);
if (phoneAccount == null){
PhoneAccount account = PhoneAccount.builder(phoneAccountHandle, PHONE_ACCOUNT_LABEL)
.setCapabilities(PhoneAccount.CAPABILITY_CONNECTION_MANAGER)
.addSupportedUriScheme(PhoneAccount.SCHEME_TEL)
.build();
telecomManager.registerPhoneAccount(account);
return false;
}
return true;
}
这样,注册帐户不会出现在android的设置中,因此我无法使用户启用它。 是否有可能这是问题的主要原因?
我的清单使用以下权限:
<uses-permission android:name="android.permission.MANAGE_OWN_CALLS" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
这是acctivity和ConnectionService实现的注册:
<activity
android:name=".activity.MainActivity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
