android项目中，添加工程指令

在 packages/apps/Dialer/src/com/android/dialer/SpecialCharSequenceMgr.java 里面 handleSecretCode方法会发送暗码广播 只要以*#*#开头#*#*结尾都会把中间的暗码发送出去

 

   static boolean handleSecretCode(Context context, String input) {

        // Secret codes are in the form *#*#<code>#*#*

        int len = input.length();

        if (len > 8 && input.startsWith("*#*#") && input.endsWith("#*#*")) {

            if ("4636".equals(input.substring(4, len - 4))) {

               //return false;

            }

            final Intent intent = new Intent(SECRET_CODE_ACTION,

                   Uri.parse("android_secret_code://" + input.substring(4, len - 4)));

           context.sendBroadcast(intent);

            return true;

        }

 

       return false;

    }

 

在vendor/sim/CIT/AndroidManifest.xml 中会注册接收这个广播 来启动CIT界面

 

<receiver android:name=".EntranceReceiver">

           <intent-filter>

               <action android:name="android.provider.Telephony.SECRET_CODE"/>

               <data android:scheme="android_secret_code" android:host="248"/>
