Getting value in Service class from another class

Getting value in Service class from another class - android

I am creating a project in which I am getting data from a server and displaying it through table view. Here is the code for Main activity class
package com.example.e_quates;

//import java.sql.SQLException;
public class MainActivity extends Activity {
List<String> strs = new ArrayList<String>();

private Intent intent;
private static final String TAG = "E-Quates";
int count=1;
public static DB db = new DB(<connection string>);
String query = "select top(10) SymbolName,LTP,Net_change,Bid_vol,Ask,Ask_vol,High_Index from NCDX_LiveData_new";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try{
strs=db.sqlexec(query);
db.closeConnection();
Log.e("connected ","success");
System.out.println("connection sucess");
tl=(TableLayout)findViewById(R.id.table);
Log.e("first row","created");
tr=new TableRow[strs.size()/7];
tv=new TextView[strs.size()];
//int i=0;
for(int i=0,j=-1;i<strs.size();i++)
{
Log.e("index "+i,"value is "+strs.get(i));
if(i%7==0)
{
j++;
Log.e("inside if","value "+i);
tr[j]=new TableRow(this);
tr[j].setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
}
tv[i] = new TextView(this);
tv[i].setText(strs.get(i));
tv[i].setId(i);
tv[i].setBackgroundResource(R.drawable.row_shape);
tr[j].addView(tv[i]);
}
for(int i=0,j=-1;i<strs.size()/7;i++)
{
tl.addView(tr[i]);
Log.e("adding row",""+i);
}
//Thread.sleep(5000);
}
catch(Exception E)
{

}
intent = new Intent(this, BroadcastService.class);
}
public void onResume() {
super.onResume();
startService(intent);
Log.e("service","called");
registerReceiver(broadcastReceiver, new IntentFilter(BroadcastService.BROADCAST_ACTION));
}
#Override

stopService(intent);
}
private BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
Log.e("in the","receiver");
updateUI(intent);
}
};
private void updateUI(Intent intent) {
strs.clear();
//String dummy = null;
Log.e("inside ","UI update");
//db.sqlexec(query);
try
{
strs = intent.getStringArrayListExtra("TAG");
//application_main apm=((application_main) getApplicationContext());
for(int i=0;i<strs.size();i++)

Here is my DB class
package com.example.e_quates;
import java.sql.Connection;

import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

}
public List<String> sqlexec(String sql)

return strs;
}
public void closeConnection()
{

} catch (SQLException e) {

}
};
And here is the service class
package com.example.e_quates;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;
import android.app.Service;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.IBinder;
import android.util.Log;
public class BroadcastService extends Service {
List<String> strs_array1 = new ArrayList<String>();
private static final String TAG = "E-Quates";
public static final String BROADCAST_ACTION = "com.example.e_quates";
private final Handler handler = new Handler();
Intent intent;
String query = "select top(10) SymbolName,LTP,Net_change,Bid_vol,Ask,Ask_vol,High_Index from NCDX_LiveData_new";
int counter = 0;
DB db1=new DB(<connection string>);
//String dummy;
#Override
public void onCreate() {
super.onCreate();
//db1.forService();
intent = new Intent(BROADCAST_ACTION);
}
#Override
public void onStart(Intent intent, int startId) {
handler.removeCallbacks(sendUpdatesToUI);
handler.postDelayed(sendUpdatesToUI, 3000); // 3 second
}
private Runnable sendUpdatesToUI = new Runnable() {
public void run() {
DisplayLoggingInfo();
handler.postDelayed(this, 3000); // 3 seconds
}
};
private void DisplayLoggingInfo() {
Log.d(TAG, "entered DisplayLoggingInfo");
strs_array1=db1.sqlexec(query);
intent.putStringArrayListExtra(TAG, (ArrayList<String>)strs_array1);
sendBroadcast(intent);
Log.e("Broadcast","done");
}
#Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onDestroy() {
handler.removeCallbacks(sendUpdatesToUI);
super.onDestroy();
}
}
The problem is that when I am calling the DB class's sqlexec() function from main activity class it is return correct value but while is I am calling it service class it is not returning the SQL output. I have tried every possible combination of calling the sqlexec() function inside the service class,but same problem is occurring.
the function db.sqlexec(query) is not returning any value..
I have referred the link for help:

Don't do any initialization in the Service constructor. Android constructs Android components (Activity, Service, BroadcastReceiver, ContentProvider) using its own mechanisms. Move all your initialization code from the constructor to the onCreate() method.
EDIT: Clarify my instructions
I am referring to this code:
List<String> strs_array1 = new ArrayList<String>();
private static final String TAG = "E-Quates";
public static final String BROADCAST_ACTION = "com.example.e_quates";
private final Handler handler = new Handler();
Intent intent;
String query = "select top(10) SymbolName,LTP,Net_change,Bid_vol,Ask,Ask_vol,High_Index from NCDX_LiveData_new";
int counter = 0;
DB db1=new DB(<connection string>);
These variables will be initialized in the constructor (even though you haven't explicitly created a constructor, one will be created for you). The constants aren't a problem, but these may cause you a problem:
private final Handler handler = new Handler();
DB db1=new DB(<connection string>);
You will want to be creating the Handler in onCreate(). I don't know what your DB class is doing, but you probably want to be creating that instance also in onCreate().
EDIT 2
I now see the code for your DB class. You can't do this like this! Your DB class extends Activity. You cannot create an instance of this class like this:
DB db1=new DB(<connection string>);
Android components (Activity, Service, BroadcastReceiver, ContentProvider) are created by the Android framework using its own mechanisms.
Why does your DB class extend Activity? It doesn't need to.

I know this is a slightly old question by now, but for those looking for answers:
I would recommend checking that you have the intent filters properly in your AndroidManifest.xml file.
It should look something like:
<activity android:name="ShareActivity">
<intent-filter>
<action android:name="android.intent.action.ACTION_SEND_FILE"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="text/plain"/>
</intent-filter>
</activity>

You are getting NewtworkOnMainThread exception because you are making network calls on the UI thread. This is a bad practice because it can block/bog down your UI thread which would make your app feel slow.
To avoid that error you have to use AsyncTask.
You have to use like this:
public class DowloadTest extends AsyncTask<String, Integer, String> {
#Override
protected void onPreExecute() {
};
#Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
// Call your web service here
return null;
}
#Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
// Update your UI here
return;
}
}

onStartCommand intent:
This may be null if the service is being restarted after its process
has gone away, and it had previously returned anything except
START_STICKY_COMPATIBILITY.

So try use:
Intent intent = new Intent(Intent.ACTION_MAIN);
intent.addCategory(Intent.CATEGORY_HOME);
startActivity(intent);
rather than finish();

Accessing functions inside a thread withing a service from an activity (socket communication)

i'm trying to get the communication between activities and a service to work.
i am pretty new to android and java, learned it my self through youtube :D, but cant find or solve this one.
at first i made an activity with a class thread which handles an ethernet socket. but i discovered when i leave the activity and switch to another the thread is destroyed. to preserve the thread i included the thread inside an service. but now i cant use the functions inside the thread (like sending/getting status). how can i get the instance of my ethernet class back to all of my activities. below i clipped my code.
the code works and run. but when i want to call my send() function or getConStatus() it crashed.
working on a client server communication for home domotics.

Why isn't it working?

Probably the most common source of binding silently failing is not having the service listed in the manifest. This does not raise an exception, so your app does not crash, but there should be a message (warning, IIRC) in LogCat pointing out your issue.
