I am working on an app which requires user login and password. My php script is running perfect. But there is some problem with my Android code. On Logging I Came across a stack trace. here is my code
public class MainActivity extends AppCompatActivity
{
EditText userName;
EditText password;
Button sButton;
HttpClient httpClient;
HttpPost httpPost;
HttpResponse httpResponse;
String username;
String pass;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
userName = (EditText)findViewById(R.id.user_id);
password = (EditText) findViewById(R.id.user_password);
sButton= (Button) findViewById(R.id.s_button);
username = userName.getText().toString();
pass = password.getText().toString();
httpClient = new DefaultHttpClient();
httpPost = new HttpPost("http://192.168.100.106/EMS/functions.php");
final JSONObject jsonObject = new JSONObject();
sButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view)
{
Thread thread = new Thread()
{
@Override
public void run()
{
try
{
jsonObject.put("username", username);
jsonObject.put("password", pass);
Log.wtf("Sent data :","username and password");
httpPost.setEntity(new StringEntity(jsonObject.toString()));
}
catch(JSONException | UnsupportedEncodingException e)
{
e.printStackTrace();
}
try {
httpResponse = httpClient.execute(httpPost);
Log.wtf("Request sent: "," httpresponse");
String str = EntityUtils.toString(httpResponse.getEntity());
Log.wtf("String recieved ",str);
JSONObject responseObject = new JSONObject(str);
String response = responseObject.getString("success");
Log.wtf("Response recieved ",response);
if(response.equals("1"))
{
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Credentials match successful.",Toast.LENGTH_SHORT).show();
Intent intent = new Intent(MainActivity.this,index.class);
startActivity(intent);
}
});
}
} catch (IOException | JSONException e) {
e.printStackTrace();
}
}
};thread.start();
}
});
}
}
And here is my stackTrace
