I'm trying to write a simple app to capture the ACTION_NEW_OUTGOING_CALL
intent and write some debugging information.
Here is my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.apis"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<receiver android:name="DialerReceiver" android:exported="false"开发者_运维技巧 android:enabled="true">
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
</application>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>
</manifest>
And here is the code for DialerReceiver:
package com.example.android.apis;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class DialerReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
debugOut("arg0: " + arg0.toString());
debugOut("arg1: " + arg1.toString());
debugOut("isOrderedBroadcast = " + isOrderedBroadcast());
}
private static void debugOut(String str) {
Log.i("DialerReceiver", str);
}
}
For reasons that I do not understand, when I install this and initiate an outgoing call, I get the following error:
WARN/ActivityManager(59): Permission Denial:
broadcasting Intent { act=android.intent.action.NEW_OUTGOING_CALL (has extras) }
from com.android.phone (pid=123, uid=1001) requires null
due to receiver com.example.android.apis/com.example.android.apis.DialerReceiver
What gives? It seems like PROCESS_OUTGOING_CALLS should be sufficient.
FWIW, if I change to a notification without permissions (TIMEZONE_CHANGED, for example), this works like a charm.
Thanks in advance.
Answering my own question.
After reviewing my manifest, it seemed like android:exported="false"
was incorrect, since Android itself would need to invoke DialerReceiver
.
When I changed this to android:export="true"
, everything worked just fine.
FWIW, I did this against the emulator (API version 8 and version 10 devices).
I am also intercepting outgoing calls to take an action. I also only have the added permission, PROCESS_OUTGOING_FILES, but I did notice that in my DialerReceiver declaration I am setting a priority:
<receiver
android:name="DialerReceiver"
android:enabled="true">
<intent-filter android:priority="2147483647">
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
</intent-filter>
</receiver>
This setup works fine for me. I can post some code from the DialerReceiver class if you need it. Are you testing this against an emulator or a phone? I have only tested against an actual phone. I am not using an emulator. Hope this helps.
