How to get the Real time when TelephonyManager.CALL_STATE_OFFHOOK is the state from onCallStateChanged method of PhoneStateListener

I am making a code for making phone calls. Everything successful except that I am unable to get the system time when TelephonyManager.CALL_STATE_OFFHOOK state from the onCallStateChanged(int state, String incomingNumber).
Similarly, I want to get the system time when TelephonyManager.CALL_STATE_IDLE state is arrived. Once I get both the values in the Mainactivity I can get the difference and based its value I can start some other activity.
For example, if the time difference between TelephonyManager.CALL_STATE_IDLE state and TelephonyManager.CALL_STATE_IDLE state is less than 30 second, then I can assume that the call is not attended and I can start another call(or to another number). I am able to do all these inside the onCallStateChanged Method of PhoneStateListener class. But unable to pass this values to Mainactivity either by variables or Methods etc. This is the code for invoking call and it is working fine
Intent myIntentCall = new Intent(Intent.ACTION_CALL, Uri.parse("tel:0123456789"));
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE)
!= PackageManager.PERMISSION_GRANTED) {
requestPermissions();
}
else
{
startActivity(myIntentCall);
}
private void requestPermissions () {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CALL_PHONE}, 1);
}
From the below piece of code, I expect the updated value of _seconds to the Mainactivity class by accessing PhoneReceiver._seconds statement. But always it remain 0. But I get the correct value for _seconds in the PhoneReceiver class. The code is given below
public class PhoneReceiver extends PhoneStateListener {
Context context;
static boolean _callStarted = false;
long _callStartTime;
long _callEndTime;
long _callDuration;
long _minutes;
static long _seconds;
public PhoneReceiver(Context context) {
this.context = context;
}
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if ((state == TelephonyManager.CALL_STATE_OFFHOOK) && !_callStarted) {
_callStarted = !_callStarted;
_callStartTime = new Date().getTime();
Toast.makeText(context, "Stage 1: " + "Off Hook -> Boolean: "+_callStarted, Toast.LENGTH_LONG).show();
}
if ((state == TelephonyManager.CALL_STATE_IDLE) && _callStarted)
{
_callEndTime = new Date().getTime();
_callDuration = _callEndTime - _callStartTime;
_minutes = (_callDuration / 1000) / 60;
_seconds = (_callDuration / 1000) % 60;
Toast.makeText(context, "Stage 2: " + "IDLE State->Boolean: "+_callStarted, Toast.LENGTH_LONG).show();
}
}
}

TelephonyManager getstate() returns zero in android

In my application, I want to put a log for the state when someone picks up the call. The getState() on the switch statement must return the correct state of the call, but it always returns zero. Here is my onRecieve() method:
public void onReceive(Context context, Intent intent) {
if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
incomingFlag = false;
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Log.i(TAG, "call OUT:"+phoneNumber);
TelephonyManager tm =
(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);
Log.e("log state", String.valueOf(tm.getCallState()));
switch (tm.getCallState()) {
case TelephonyManager.CALL_STATE_RINGING:
incomingFlag = true;
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;
default:
Log.e("ds","Error");
}
}
manifest file :
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".BroadCast" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.NEW_OUTGOING_CALL"/>

</receiver>
Permissions :
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name = "android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>
The onCreate() method mentioned above is in a seperate class I created called BroadCast, and I call it by creating a new instance of it.
Please let me know if more details are required.

Try to use a BroadcastReceiver to handle the incoming call.
In your onResume, set up the receiver
IntentFilter filter2 = new IntentFilter(TelephonyManager.ACTION_PHONE_STATE_CHANGED);
filter2.setPriority(99999);
this.registerReceiver(incomingCallReceiver, filter2);
and handle it such as
BroadcastReceiver incomingCallReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
final Bundle bundle = intent.getExtras();
if (bundle == null) return;
// Incoming call
// Get the state
String state = bundle.getString(TelephonyManager.EXTRA_STATE);
// Process the states
if ((state != null) && (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))) {
// Ringing State
}
if ((state != null) && (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_IDLE))) {
// Idle State
}
if ((state != null) && (state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_OFFHOOK))) {
// Offhook State
}
}
};

My onReceive method get called multiple and trigger onCreate from my MainActivity (Wear)

I am fairly new to android. I am trying to send data from my tablet to my phone using a WearableListenerService. This part works well, I can see through logs that the data is sent. The problem is that I receive the data from the tablet in the Listener class and I have to transmit it to Mainactivity in order to update my Views. To do this I use a LocalBroadcaster and I implemented the onReceive method in my MainActivity. So when I give the order to send the data from the phone the onReceive gets called multiple time most of the time between 2 or 3 times and furthermore the activity is recreated because onCreate is triggered by this method (I don't know if this behavior is expected).
Here is the code:
DataLayerListenerService.java (Listener)
public class DataLayerListenerService extends WearableListenerService {
// Tag for Logcat
private static final String TAG = "DataLayerService";
private int notificationId = 001;
private String notif;
// Member for the Wear API handle
GoogleApiClient mGoogleApiClient;
#Override
public void onCreate() {
super.onCreate();
// Start the Wear API connection
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Wearable.API)
.build();
mGoogleApiClient.connect();
}
//#Override
public void onDataChanged(DataEventBuffer dataEvents) {
Log.v(TAG, "onDataChanged: " + dataEvents);
for (DataEvent event : dataEvents) {
if (event.getType() == DataEvent.TYPE_CHANGED) {
Log.e(TAG, "DataItem Changed: " + event.getDataItem().toString() + "\n"
+ DataMapItem.fromDataItem(event.getDataItem()).getDataMap());
String path = event.getDataItem().getUri().getPath();
switch (path) {
case DataLayerCommons.NOTIFICATION_PATH:
Log.v(TAG, "Data Changed for NOTIF_PATH: " + event.getDataItem().toString());
DataMapItem dataMapItem = DataMapItem.fromDataItem(event.getDataItem());
notif = dataMapItem.getDataMap().getString(DataLayerCommons.NOTIFICATION_KEY);
Intent intent = new Intent(NOTIFICATION_RECEIVED);
intent.putExtra(NOTIFICATION_RECEIVED, notif);
LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
break;
case DataLayerCommons.COUNT_PATH:
Log.v(TAG, "Data Changed for COUNT_PATH: " + event.getDataItem() + "\n"
+ "Count data = " + DataMapItem.fromDataItem(event.getDataItem())
.getDataMap().getInt(DataLayerCommons.COUNT_KEY));
break;
default:
Log.v(TAG, "Data Changed for unrecognized path: " + path);
break;
}
} else if (event.getType() == DataEvent.TYPE_DELETED) {
Log.v(TAG, "DataItem Deleted: " + event.getDataItem().toString());
}
}
}
}

Thanks for the help

I would suggest using Application class to store your Activity instead of BroadcastReceiver registering.
What I mean:
in Application class create a variable that stores your activity:
class MyApp extends Application {
public static MyActivity activity;
}
to link save into this variable current activity at onCreate and release while onDestroy.
Somehow:
public MyActivity extends Activity {
void onCreate() {
MyApp.activity = this;
}
void onDestroy() {
MyApp.activity = null;
}
void redraw() {
//redraw
}
}
inside the service do something like this:
class MyService extends WearableListenerService {
void onDataChanged() {
if (MyApp.activity != null) {
MyApp.activity.redraw()
}
}
}
do not forget to set application in the manifest:
<application
android:name=".MyApp"
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/Theme.AppCompat">

android read USSD response

I'm trying to read USSD response to get Sim balance amount etc, and I'm having issues, I have been reading many questions related to that on Stackoverflow, nothing has worked so far. Except for this that came close: Prevent USSD dialog and read USSD response?. by #HenBoy331
But i'm still having issues with it. My broadcast receiver doesn't get called too. I'm using 4.4.2
But it shows nothing. I can't seem to parse the message and get the balance.
I have a MainActivity to make the phone call, ReceiverActivity to implement broadcast receiver, USSDService class to get the USSD response.
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this, USSDService.class));
dailNumber("100");
}
private void dailNumber(String code) {
String ussdCode = "*" + code + Uri.encode("#");
startActivity(new Intent("android.intent.action.CALL", Uri.parse("tel:" + ussdCode)));
}
}
RecieverActivity.java
public class RecieverActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filter = new IntentFilter("com.times.ussd.action.REFRESH");
this.registerReceiver(new Receiver(), filter);
}
public class Receiver extends BroadcastReceiver {
private String TAG = "XXXX";
#Override
public void onReceive(Context context, Intent intent) {
String message = intent.getStringExtra("message");
Log.i(TAG, "Got message: " + message);
}
}
}
USSDService.java
public class USSDService extends AccessibilityService {
public String TAG = "XXXX";
#Override
public void onAccessibilityEvent(AccessibilityEvent event) {
Log.d(TAG, "onAccessibilityEvent");
AccessibilityNodeInfo source = event.getSource();
/* if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !event.getClassName().equals("android.app.AlertDialog")) { // android.app.AlertDialog is the standard but not for all phones */
if (event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED && !String.valueOf(event.getClassName()).contains("AlertDialog")) {
return;
}
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && (source == null || !source.getClassName().equals("android.widget.TextView"))) {
return;
}
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED && TextUtils.isEmpty(source.getText())) {
return;
}
List<CharSequence> eventText;
if(event.getEventType() == AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED) {
eventText = event.getText();
} else {
eventText = Collections.singletonList(source.getText());
}
String text = processUSSDText(eventText);
if( TextUtils.isEmpty(text) ) return;
// Close dialog
performGlobalAction(GLOBAL_ACTION_BACK); // This works on 4.1+ only
Log.d(TAG, text);
// Handle USSD response here
Intent intent = new Intent("com.times.ussd.action.REFRESH");
intent.putExtra("message", text);
sendBroadcast(intent);
}
private String processUSSDText(List<CharSequence> eventText) {
for (CharSequence s : eventText) {
String text = String.valueOf(s);
// Return text if text is the expected ussd response
if( true ) {
return text;
}
}
return null;
}
#Override
public void onInterrupt() {
}
#Override
protected void onServiceConnected() {
super.onServiceConnected();
Log.d(TAG, "onServiceConnected");
AccessibilityServiceInfo info = new AccessibilityServiceInfo();
info.flags = AccessibilityServiceInfo.DEFAULT;
info.packageNames = new String[]{"com.android.phone"};
info.eventTypes = AccessibilityEvent.TYPE_WINDOW_STATE_CHANGED | AccessibilityEvent.TYPE_WINDOW_CONTENT_CHANGED;
info.feedbackType = AccessibilityServiceInfo.FEEDBACK_GENERIC;
setServiceInfo(info);
}
}

Please, is there any way i'm implementing this wrongly, Or perhaps there is a new way to get USSD responses which works?

After the launch, change the settings manually
Setting->Accessibility Setting -> You can see a option 'your app name'. Turn it on. (This has to be done from as a part of application flow(not manual))

instead of using broadcast receiver use these two lines of code in
add this code in MainActivity
public static void setTextViewToModify(String Text) {
textView.setText(Text);}
and add this in service class with in onAccessibityEvent
MainActivity.setTextViewToModify(text);

Listening for phone code not executing?

My app plays audio, and so I want to mute my app's audio when the user gets a call. That way the music won't be playing over the users call. I have used phoneStateListener , but for some reason the methods in it aren't executing-I know because the logs aren't displaying:
PhoneStateListener phoneStateListener = new PhoneStateListener() {
#Override
public void onCallStateChanged(int state, String incomingNumber) {
if (state == TelephonyManager.CALL_STATE_RINGING) {
//Incoming call: Pause music
TwentySeconds.stopTimer(); //Stop service which mutes app
Intent i = new Intent(BaseActivity.this, Main_Menu.class);
startActivity(i);
Toast.makeText(BaseActivity.this, "INCOMING CALL", Toast.LENGTH_SHORT).show();
Log.v(TAG, "INCOMING CALL");
} else if (state == TelephonyManager.CALL_STATE_IDLE) {
//Not in call: Play music
Log.v(TAG, "NOT IN A CALL");
} else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
//A call is dialing, active or on hold
TwentySeconds.stopTimer(); //Stop service which mutes app
Intent i = new Intent(BaseActivity.this, Main_Menu.class);
startActivity(i);
Log.v(TAG, "CALL IS ACTIVE!");
Toast.makeText(BaseActivity.this, "DIALING", Toast.LENGTH_SHORT).show();
}
}
};
I have looked all over the web to find out how to do this--One way is I found is to use the intent, but that requires extending BroadcastReceiver, and I can't extend two things. So, for now, the phoneStateListener is doing absolutely nothing. I really appreciate all of your help in fixing my PhoneStateListener.
Thanks,
Rich

Did you forget to quote the TelephonyManager?
TelephonyManager manager = this.getSystemService(TELEPHONY_SERVICE);
Try this:
public class PhoneCallStateActivity extends Activity {
TelephonyManager manager;
#override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
manager = (TelephonyManager) this.getSystemService(TELEPHONY_SERVICE);
manager.listen(new MyPhoneStateListener(), PhoneStateListener.LISTEN_CALL_STATE);
}
class MyPhoneStateListener extends PhoneStateListener{
#override
public void onCallStateChanged(int state, String incomingNumber) {
switch(state) {
case TelephonyManager.CALL_STATE_IDLE:
//TODO:
break;
case TelephonyManager.CALL_STATE_RINGING:
//TODO：
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//TODO:
break;
default:
break;
}
}
super.onCallStateChanged(state, incomingNumber);
}
}

I looked at your code,it is good. But i am just thinking about your manifest file, did you given enough permissions to read phone state. Have a look at my manifest file (which is working):
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.truiton.phonestatelistener"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".PhoneStateListenerActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
It is better to access / use this "Custom Phone State Listener" class with the TelephonyManager like as follows:
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
public class PhoneStateListenerActivity extends ActionBarActivity {
TelephonyManager tManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
tManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
tManager.listen(new CustomPhoneStateListener(this),
PhoneStateListener.LISTEN_CALL_STATE
| PhoneStateListener.LISTEN_CELL_INFO // Requires API 17
| PhoneStateListener.LISTEN_CELL_LOCATION
| PhoneStateListener.LISTEN_DATA_ACTIVITY
| PhoneStateListener.LISTEN_DATA_CONNECTION_STATE
| PhoneStateListener.LISTEN_SERVICE_STATE
| PhoneStateListener.LISTEN_SIGNAL_STRENGTHS
| PhoneStateListener.LISTEN_CALL_FORWARDING_INDICATOR
| PhoneStateListener.LISTEN_MESSAGE_WAITING_INDICATOR);
}
}
Here we are setting the tManager.listen method a new object for CustomPhoneStateListener and in the events parameter a bitwise-OR combination of Android PhoneStateListener LISTEN_ flags is passed.
You can set your own custom phone state listener, (I am just adding mine here) :
public class CustomPhoneStateListener extends PhoneStateListener {
public CustomPhoneStateListener(Context context) {
mContext = context;
}
#Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
Log.i(LOG_TAG, "onCallStateChanged: CALL_STATE_IDLE");
break;
case TelephonyManager.CALL_STATE_RINGING:
Log.i(LOG_TAG, "onCallStateChanged: CALL_STATE_RINGING");
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i(LOG_TAG, "onCallStateChanged: CALL_STATE_OFFHOOK");
break;
default:
Log.i(LOG_TAG, "UNKNOWN_STATE: " + state);
break;
}
}
