java - android read USSD response -
i'm trying read ussd response sim balance amount etc, , i'm having issues, have been reading many questions related on stackoverflow, nothing has worked far. except came close: prevent ussd dialog , read ussd response?. @henboy331
but i'm still having issues it. broadcast receiver doesn't called too. i'm using 4.4.2
but shows nothing. can't seem parse message , balance.
i have mainactivity make phone call, receiveractivity implement broadcast receiver, ussdservice class 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 standard not 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); // works on 4.1+ 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) { (charsequence s : eventtext) { string text = string.valueof(s); // return text if text 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); } } androidmanifest
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.dialussd"> <uses-permission android:name="android.permission.call_phone" /> <uses-permission android:name="android.permission.receive_boot_completed" /> <application android:allowbackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsrtl="true" android:theme="@style/apptheme"> <activity android:name=".mainactivity"> <intent-filter> <action android:name="android.intent.action.main" /> <category android:name="android.intent.category.launcher" /> </intent-filter> </activity> <service android:name=".services.ussdservice" android:enabled="true" android:exported="true" android:permission="android.permission.bind_accessibility_service"> <intent-filter> <action android:name="android.accessibilityservice.accessibilityservice" /> </intent-filter> <meta-data android:name="android.accessibilityservice" android:resource="@xml/config_service" /> </service> <receiver android:name=".recieveractivity$receiver" > <intent-filter> <action android:name="android.intent.action.boot_completed" /> </intent-filter> </receiver> </application> </manifest> please, there way i'm implementing wrongly, or perhaps there new way ussd responses works?
after launch, change settings manually
setting->accessibility setting -> can see option 'your app name'. turn on. (this has done part of application flow(not manual))
