Android 阻止USSD对话框并读取USSD响应？
我做了很多关于ussd的研究，但我无法阅读ussd respone以及如何防止像此应用程序这样的ussd对话框 我安装了这个重新启动我的手机（S2 android 4.0.3），发送ussd代码，但什么也没发生，有人告诉我我必须阅读日志，但我如何才能做到这一点 我尝试使用这些代码从日志中读取USSD USSD.javaAndroid 阻止USSD对话框并读取USSD响应？,android,ussd,Android,Ussd,我做了很多关于ussd的研究，但我无法阅读ussd respone以及如何防止像此应用程序这样的ussd对话框 我安装了这个重新启动我的手机（S2 android 4.0.3），发送ussd代码，但什么也没发生，有人告诉我我必须阅读日志，但我如何才能做到这一点 我尝试使用这些代码从日志中读取USSD USSD.java package com.example.ussd; import java.io.BufferedReader; import java.io.IOE

它可以在Android 2.3中使用，但我不完全确定它是否可以在高级版本中使用，请按照说明操作：
adb外壳logcat-v time-b main PhoneUtils:D>output.txtoutput.txtdisplaymiplete可以使用辅助功能服务。 首先创建一个服务类：
public class USSDService extends AccessibilityService {
public static String TAG = USSDService.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;

和。使用IExtendedNetworkService.aidl
在路径com\android\internal\telephony中创建此文件
package com.android.internal.telephony;
/**
* Interface used to interact with extended MMI/USSD network service.
*/
interface IExtendedNetworkService {
/**
* Set a MMI/USSD command to ExtendedNetworkService for further process.
* This should be called when a MMI command is placed from panel.
* @param number the dialed MMI/USSD number.
*/
void setMmiString(String number);
/**
* return the specific string which is used to prompt MMI/USSD is running
*/
CharSequence getMmiRunningText();
/**
* Get specific message which should be displayed on pop-up dialog.
* @param text original MMI/USSD message response from framework
* @return specific user message correspond to text. null stands for no pop-up dialog need to show.
*/
CharSequence getUserMessage(CharSequence text);
/**
* Clear pre-set MMI/USSD command.
* This should be called when user cancel a pre-dialed MMI command.
*/
void clearMmiString();
}
在manifast中添加com.android.ussd.IExtendedNetworkService筛选器：

一旦设备必须重新启动才能运行你有解决方案吗？还没有，你对这个问题有什么想法吗？没有，我只是在尝试解决，但没有任何进展。每当你找到解决方案时，请在这个主题中回复：）你确定我会做杰克。这在棒棒糖上非常有效，但在4.2.2和4.0.3上没有成功。我想这个问题已经解决了副具体说明。上述代码适用于三星Duos（4.0.4）、一加一（5.1.1）、Xiomi mi（4.4），但不适用于Micromax A177（4.2.2）、Micromax A905（4.0.4）、联想（4.2.2）。如果您可以检查相同的问题并寻找解决方案，请检查。。是的，在某些设备上，它不起作用。在某些设备上，它是com.android.phone.UssdAlertActivity，而不是android.app.alertdialogy。请检查我的新答案。我是从我的角度让它起作用的。请检查！@hashemkaled，请查看此处的示例：在所有设备/android版本上，或者是否存在任何limitation？@Alex这只能在4.2.2之前的Android版本中实现。在4.2.2中，由于安全风险，IExtendedNetworkService似乎已被谷歌删除。请参阅谷歌发布的问题-
