java.lang.IllegalStateException目标主机不能为null连接到数据库

Question

I am trying to connect to localhost/myfile.php on my computer. The PHP file converts database data into JSON which I want to parse after connecting. When I try to connect, I get

Target host must not be null, or set in parameters. scheme=null, host=null,   
path=10.0.0.9/myfile.php

Any ideas?

public void getData(){
    String result = "";
    InputStream isr = null;
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("10.0.0.9/myfile.php");  
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        isr = entity.getContent();
}
catch(Exception e){
        Log.e("log_tag", "Error in http connection "+e.toString());
        resultView.setText("Couldnt connect to database" + e);

Looks like you're missing the URI scheme.

Try with new HttpPost("http://10.0.0.9/myfile.php");
