我正在尝试将数据从我的Android应用程序发送到localhost但是数据不在localhost上提交。我已经创建了php文件（register.php）并保存在www目录中。当我手动提交数据时，php文件工作正常。 下面是我的MainActivity.java文件。
public void onButtonClickListener()
{
on_submit=(Button)findViewById(R.id.onsubmit);
on_submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String str_personname = personname.getText().toString();
String str_contactno = contactno.getText().toString();
String str_alternateno = alternateno.getText().toString();
String str_emailid = emailid.getText().toString();
String str_currentline1 = currentline1.getText().toString();
String str_currentline2 = currentline2.getText().toString();
String str_currentlocality = currentlocality.getText().toString();
String str_currentcity = currentcity.getText().toString();
String str_currentstate = currentstate.getText().toString();
String str_currentpin = currentpin.getText().toString();
String str_permanentline1 = permanentline1.getText().toString();
String str_permanentline2 = permanentline2.getText().toString();
String str_permanentlocality = permanentlocality.getText().toString();
String str_permanentcity = permanentcity.getText().toString();
String str_permanentstate = permanentstate.getText().toString();
String str_permanentpin = permanentpin.getText().toString();
String str_dateofinterview = dateofinterview.getText().toString();
String str_applyfor = applyfor.getText().toString();
String str_refrencename = refrencename.getText().toString();
String str_refrenceid = refrenceid.getText().toString();
String type = "register";
Backendworker backendworker = new Backendworker(MainActivity.this);
backendworker.execute(type, str_personname, str_contactno, str_alternateno, str_emailid, str_currentline1, str_currentline2, str_currentlocality, str_currentcity,
str_currentstate, str_currentpin, str_permanentline1, str_permanentline2, str_permanentlocality, str_permanentcity, str_permanentstate,
str_permanentpin, str_dateofinterview, str_applyfor, str_refrencename, str_refrenceid);
Toast.makeText(MainActivity.this, "Action performed on button click", Toast.LENGTH_SHORT).show();
}
});
}
我已经在oncreate（）方法中定义了他们的id。 下面是我的Backendworker.java类

代码在任何地方都不会显示任何错误。 下面是php文件

如果有人知道ans那么请帮忙。 感谢...
