I wanted to make a service which will check my SMS in every 20 sec if there are any unread SMS then send it to my website then mark as read for posting data to website I used asynctask and it worked fine when I tried manually (by making button click type app) but in side service I cant define
runOnUiThread(new Runnable() {
@Override
public void run() { new MyAsyncTask().execute(sender,time,message);}
});
it is unable to identify and asks me to define runOnUiThread Is there any way to call my asynctask from the place where I am calling in below code
public class TestService extends Service {
String sender = null;
String time = null;
String message = null;
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
@Override
public void onCreate() {
Toast.makeText(getApplicationContext(), "Service Created", 1).show();
super.onCreate();
}
@Override
public void onDestroy() {
Toast.makeText(getApplicationContext(), "Service Destroy", 1).show();
super.onDestroy();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(getApplicationContext(), "Service Running ", 1).show();
new Thread(new Runnable() {
public void run() {
ContentValues values = new ContentValues();
Uri mSmsinboxQueryUri = Uri.parse("content://sms/inbox");
String[] columns = new String[] { "_id", "thread_id",
"address", "person", "date", "body", "type" };
Cursor cursor1 = getContentResolver().query(mSmsinboxQueryUri,
null, "read=0", null, null);
DateFormat formatter = new SimpleDateFormat(
"dd/MM/yyyy hh:mm:ss.SSS");
Calendar calendar = Calendar.getInstance();
if (cursor1.getCount() > 0) {
cursor1.moveToFirst();
do {
// Retrieving sender number
sender = (cursor1.getString(cursor1
.getColumnIndex(columns[2])).toString());
// Retriving time of reception
long ms = cursor1.getLong(cursor1
.getColumnIndex(columns[4]));
calendar.setTimeInMillis(ms);
time = formatter.format(calendar.getTime()).toString();
// Retriving the message body
message = (cursor1.getString(cursor1
.getColumnIndex(columns[5])).toString());
runOnUiThread(new Runnable() {
@Override
public void run() {
new MyAsyncTask()
.execute(sender, time, message);
}
});
} while (cursor1.moveToNext());// end of while
}// end of if
// set as read
values.put("read", true);
getContentResolver().update(Uri.parse("content://sms/inbox"),
values, null, null);
}
}).start();
return super.onStartCommand(intent, flags, startId);
}
private class MyAsyncTask extends AsyncTask<String, Integer, Double> {
@Override
protected Double doInBackground(String... params) {
postData(params[0], params[1], params[2]);
return null;
}
protected void onPostExecute(Double result) {
// pb.setVisibility(View.GONE);
Toast.makeText(getApplicationContext(), "command sent",
Toast.LENGTH_LONG).show();
}
protected void onProgressUpdate(Integer... progress) {
// pb.setProgress(progress[0]);
}
public void postData(String sender, String time, String message) {
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(
"http://www.mysite.co.nf/reciever.php");
try {
// Add your data
List<NameValuePair> nameValuePairs =
new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("sender", sender));
nameValuePairs.add(new BasicNameValuePair("time", time));
nameValuePairs.add(new BasicNameValuePair("message", message));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
} catch (ClientProtocolException e) {} catch (IOException e) {}
}
}
}
Service
does not have a method called runOnUiThread()
. You're assuming that the method from Activity
is also defined for a Service
, but it's not.
Solution, just define a method that does exactly that. Here's a simplified example, the rest of your code would remain unchanged.
import android.os.Handler;
public class TestService extends Service {
Handler handler;
@Override
public void onCreate() {
// Handler will get associated with the current thread,
// which is the main thread.
handler = new Handler();
super.onCreate();
}
private void runOnUiThread(Runnable runnable) {
handler.post(runnable);
}
}
For more info, see the docs for Handler. It's used to dump some work onto a specific thread. In this case, the Handler
gets associated with the UI thread, since the UI thread always calls Service.onCreate()
.
