I'm starter with Android and I'm trying an example to get some information from an edittext and send that to my localhost and if my Localdatabase isset that so echo something, but whatever I did, it doesn't work and OutputStreamWriter work in Android Studio when I check it with debugger but nothing send to my local database.
Below I share my codes. The error is that $_POST["email"] doesn't work and errors that email is undefined?!
//It's my MainActivity's codes
public class MainActivity extends AppCompatActivity {
Button show;
TextView txt;
EditText edt;
public static Context context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context=MainActivity.this;
edt=(EditText)findViewById(R.id.edt);
show=(Button)findViewById(R.id.show);
txt=(TextView)findViewById(R.id.txt);
show.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new AsynctaskTest("http://152.144.1.215/sadegh",edt.getText().toString()).execute();
}
});
}
}
here is my AsynctaskGetData's codes:
public class AsynctaskTest extends AsyncTask<String,Integer,String>{
public String link="";
public String email="";
public StringBuilder builder;
ProgressDialog progressDialog;
public AsynctaskTest(String link,String email){
this.link=link;
this.email=email;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
progressDialog=new ProgressDialog(MainActivity.context);
progressDialog.setTitle("Processing...");
progressDialog.setMessage("Please Wait...");
progressDialog.show();
}
@Override
protected String doInBackground(String... strings) {
try {
String data=URLEncoder.encode("email","UTF-8")+"="+URLEncoder.encode(email,"UTF-8");
URL url=new URL(link);
URLConnection connection=url.openConnection();
connection.setDoOutput(true);
OutputStreamWriter writer=new OutputStreamWriter(connection.getOutputStream());
writer.write(data);
writer.flush();
BufferedReader reader=new BufferedReader(new InputStreamReader(connection.getInputStream()));
builder=new StringBuilder();
String line=null;
while ((line=reader.readLine())!=null){
builder.append(line);
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return builder.toString();
}
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
progressDialog.dismiss();
Toast.makeText(MainActivity.context, s, Toast.LENGTH_SHORT).show();
}
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
}
}
It's my php code
<?php
$email=$_POST["email"];
echo "hello"
?>
