如何通过额外的BroadcastReceiver来，开始的时候ACTION_CALL [英] How to pass Extra to BroadcastReceiver, when initiating ACTION_CALL

问题描述

我开始从我的活动新的呼叫。并试图通过一个布尔额外的费用。

 公共类CallInitiatingActivity延伸活动{    @覆盖
    保护无效的onCreate（捆绑savedInstanceState）{
        super.onCreate（savedInstanceState）;        意向意图=新意图（Intent.ACTION_CALL，Uri.parse（电话：+号））;
        intent.putExtra（com.demoapp.CUSTOM_CALL，真正的）;
        startActivity（意向）;
    }
}
 

我也有注册一个BroadcastReceiver，它监听打出的电话：

 ＆lt;接收机器人：OutgoingCallListenerNAME =机器人：出口=真正的＆GT;
    ＆LT;意向过滤器的android：优先=0＆GT;
        ＆lt;作用机器人：名字=android.intent.action.NEW_OUTGOING_CALL/＆GT;
        ＆LT;类机器人：名字=android.intent.category.DEFAULT/＆GT;
    ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
 

基本上我期待的onReceive看到我的额外费用，但不知何故，不通过：

 公共类OutgoingCallListener扩展广播接收器{    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{
        捆绑额外= intent.getExtras（）;        对于（字符串键：extras.keySet（））{
            Log.i（Constant.LOG_TAG，键+：+ extras.get（键））;
        }
    }
}
 

输出：

  android.phone.extra.ALREADY_CALLED：假的
android.intent.extra.PHONE_NUMBER：+ 370652xxxxx
com.htc.calendar.event_uri：空
android.phone.extra.ORIGINAL_URI：电话：+ 370652xxxxx
 

解决方案

您定制额外的是您用来启动呼活动意向present。但它不会复制到广播作为实际调用机制的一部分 NEW_OUTGOING_CALL 意图。这些2操作是不同的，只有间接彼此相关。只有Android系统本身可以播放 NEW_OUTGOING_CALL 意图。

您不能添加自己的额外这种意图。你需要想出另一种方式来做到不管它是你所要完成的。

I'm initiating new call from my activity. And trying to pass a boolean extra.

public class CallInitiatingActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + number));
        intent.putExtra("com.demoapp.CUSTOM_CALL", true);
        startActivity(intent);
    }
}

I also have a BroadcastReceiver registered, which listens for outgoing calls:

<receiver android:name=".OutgoingCallListener" android:exported="true" >
    <intent-filter android:priority="0" >
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</receiver>

Basically what I'm expecting onReceive to see my extra, but somehow it is not passed:

public class OutgoingCallListener extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();

        for (String key : extras.keySet()) {
            Log.i(Constant.LOG_TAG, key + ": " + extras.get(key));
        }
    }
}

Output:

android.phone.extra.ALREADY_CALLED:false
android.intent.extra.PHONE_NUMBER:+370652xxxxx
com.htc.calendar.event_uri:null
android.phone.extra.ORIGINAL_URI:tel:+370652xxxxx

解决方案

Your custom extra is present in the Intent that you use to start the "call" activity. But it isn't copied into the NEW_OUTGOING_CALL Intent that is broadcast as a part of the actual call mechanism. These 2 operations are distinct and only indirectly related to each other. Only the Android system itself can broadcast the NEW_OUTGOING_CALL Intent.

You can't add your own extras to this Intent. You'll need to come up with another way to do whatever it is you are trying to accomplish.
