我的尝试：

尝试{

new Intent（android.intent.action.CALL，Uri.parse（phoneNumber）），1）;

String msg = eExcept.toString（）;
this.view.append（ \ n \\ n+\ n+ msg）;
}
}

Hi everybody,
Hello guys, I have recently assigned to work on a new Android project, it is a challenging one, and I liked it, here is the problem matter I faced.
I need to intercept a ussd message, I have tried to investigate through but I didn't find that really can help.
Please indicate me anything that I can start with.
Lot's of Thanks
What I have tried:
protected void call(String phoneNumber) {
try {
startActivityForResult(
new Intent("android.intent.action.CALL", Uri.parse(phoneNumber)), 1);
} catch (Exception eExcept) {
String msg = eExcept.toString();
this.view.append("\n\n " + "\n" + msg);
}
}
public class MyService extends AccessibilityService {
public static String TAG = MyService.class.getSimpleName();
@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
}
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);
}
}
