How To Detect Phone Call Broadcast Receiver In Android
I am building an application in android, which will perform an action when any phone call will come in my phone. I have tried this with broadcast receiver and phone state listener.
Solution 1:
Solution 2:
<receiverandroid:name="ClassName"><intent-filter><actionandroid:name="android.intent.action.PHONE_STATE">/action>
</intent-filter></receiver>Its working!!
Solution 3:
Here is an example from a Chinese BBS.
publicclassPhoneStatReceiverextendsBroadcastReceiver{
privatestaticfinalStringTAG="PhoneStatReceiver";
privatestaticbooleanincomingFlag=false;
privatestaticStringincoming_number=null;
@OverridepublicvoidonReceive(Context context, Intent intent) {
//如果是拨打电话if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
incomingFlag = false;
StringphoneNumber= intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:"+phoneNumber);
}else{
//如果是来电TelephonyManagertm=
(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
switch (tm.getCallState()) {
case TelephonyManager.CALL_STATE_RINGING:
incomingFlag = true;//标识当前是来电
incoming_number = intent.getStringExtra("incoming_number");
Log.i(TAG, "RINGING :"+ incoming_number);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
if(incomingFlag){
Log.i(TAG, "incoming ACCEPT :"+ incoming_number);
}
break;
case TelephonyManager.CALL_STATE_IDLE:
if(incomingFlag){
Log.i(TAG, "incoming IDLE");
}
break;
}
}
}
}
Register it in your AndroidManifest.xml.
<receiverandroid:name=".filter.PhoneStatReceiver"><intent-filter><actionandroid:name="android.intent.action.PHONE_STATE"/><actionandroid:name="android.intent.action.NEW_OUTGOING_CALL" /></intent-filter></receiver><uses-permissionandroid:name="android.permission.READ_PHONE_STATE"></uses-permission><uses-permissionandroid:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission>Solution 4:
I have read here https://gist.github.com/ftvs/e61ccb039f511eb288ee
It works fine for me. Android version 5.0.
My task had consisted next.
My application must observer all calls events. And distinguish incoming, outgoing calls. Any time when the incoming call has finished it must create the new outgoing call. Phone number specified in settings number. This phone number is the number of gate controller. (https://www.pal-es.com/3g-eng) It is cheating for opening automatic gates for users, not in the whitelist. This application works into a standalone smartphone and is used decided for this task only.
And some features you can find here too.
For example:
- how update textView value from Runnable thread
- I make outgoing call not from BroadcastReceiver class, because it impossible. It need make from MainActivity. Havy fun))) Try it.
MainActivity.java
package com.example.root.test02;
import android.content.Intent;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Date;
