拨打电话自动添加IP地址

第一步：

添加权限：

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

第二步：

注册receiver

</receiver>

第三步：

将IP地址存入SharedPreferences

SharedPreferences sp = getSharedPreferences("ip", MODE_PRIVATE);
sp.edit().putString("ipNumber", et.getText().toString()).commit();

第四步：

获取拨打的电话号码，从SharedPreferences 中取出IP地址加的电话号码前

SharedPreferences sp = context.getSharedPreferences("ip", Context.MODE_PRIVATE);
String ipNumber = sp.getString("ipNumber", "");

//把IP线路号码添加至用户拨打号码的前面
number = ipNumber + number;

//把新的号码重新放入广播中
setResultData(number);
//拦截广播
abortBroadcast();
