我想实现一个简单的应用程序,使我可以过滤传入的电话。我试图使用BroadcastReceiver来检测呼叫,然后使用TelecomManager结束呼叫,但是TelecomManager的endCall()需要系统特权。
我现在正在尝试遵循this guide来实现调用应用程序,其中涉及实现ConnectionService类,并使用该类来创建/处理“ Connections”。连接代表一个电话,并且具有setDisconnected()函数,我打算使用该函数来过滤呼叫。
问题在于,似乎我的ConnectionService类未正确绑定到TelecomManager,并且未调用log语句,因此未调用其功能。如何使其正确绑定?
我对ConnectionService的实现:
public class CallHandler extends ConnectionService {
@Override
public Connection onCreateOutgoingConnection (PhoneAccountHandle connectionManagerPhoneAccount,
final ConnectionRequest request) {
return null;
}
@Override
public void onCreateOutgoingConnectionFailed (PhoneAccountHandle connectionManagerPhoneAccount,
final ConnectionRequest request) {
}
@Override
public void onCreateIncomingConnectionFailed (PhoneAccountHandle connectionManagerPhoneAccount,
final ConnectionRequest request) {
}
@Override
public Connection onCreateIncomingConnection (PhoneAccountHandle connectionManagerPhoneAccount,
final ConnectionRequest request) {
Log.i("~~~~INFO", "onCreateIncomingConnection was called!!!!");
return null;
}
public class TestConnection extends Connection {
@Override
public void onAnswer() {
}
@Override
public void onReject() {
}
}
}

main的onCreate中的代码用于注册CallHandler:
private void register() {
Log.i("Info:", "Register Phone account called");
TelecomManager manager = (TelecomManager) getSystemService(TELECOM_SERVICE);
PhoneAccountHandle phoneAccountHandle = new PhoneAccountHandle(
new ComponentName(getPackageName(),
CallHandler.class.getName()), "CallHandlerId");
PhoneAccount.Builder builder = PhoneAccount.builder(phoneAccountHandle, "CustomAccount");
builder.setCapabilities(PhoneAccount.CAPABILITY_SELF_MANAGED);
PhoneAccount phoneAccount = builder.build();
manager.registerPhoneAccount(phoneAccount);
}
最佳答案
如果要拒绝某些来电,则不应使用PhoneAccount.CAPABILITY_SELF_MANAGED
,因为它只能用于管理自己的电话。您的phoneAccount上需要PhoneAccount.CAPABILITY_CALL_PROVIDER, PhoneAccount.CAPABILITY_CONNECTION_MANAGER
并将其设置为系统上的默认phoneAccount。

享受编码。
