Connection Loss Handling in AsyncTask in Android

Connection Loss Handling in AsyncTask in Android - android

In My application i have read all the record from the DataBase SqlServer by using REST API.But there is some problem when connection loss at intermediate execution of protected DetailsTimeTable doInBackground(String... params). Then my app closed with error Unfortunately app has stopped
Here is my Code:
public class Monday_Time extends ListActivity {
ArrayList<String> itemsList = new ArrayList<String>();
private ProgressDialog progressDialog;
private BroadcastReceiver mconn;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.time_table_list);
// Bundle bundle = getIntent().getExtras();
Toast.makeText(this, MainActivity.branch_static, Toast.LENGTH_LONG).show();
// registerReceiver(new NetworkBroadCast(), new IntentFilter(ConnectivityManager.EXTRA_IS_FAILOVER));
mconn = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false);
String reason = intent.getStringExtra(ConnectivityManager.EXTRA_REASON);
boolean isfailOver = intent.getBooleanExtra(ConnectivityManager.EXTRA_IS_FAILOVER, false);
NetworkInfo currentNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
NetworkInfo otherNetworkInfo = (NetworkInfo) intent.getParcelableExtra(ConnectivityManager.EXTRA_OTHER_NETWORK_INFO);
Log.d("Connectivity", Boolean.toString(noConnectivity));
Log.d("Reson ", reason);
Log.d("FailOver", Boolean.toString(isfailOver));
}
};
registerReceiver(mconn, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
new AsyncDetailsTimeTable().execute(MainActivity.branch_static.trim(), MainActivity.sem_static.trim(), MainActivity.sec_static.trim(), "Monday");
}
public class AsyncDetailsTimeTable extends AsyncTask<String, Void, DetailsTimeTable> {
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog = new ProgressDialog(Monday_Time.this);
progressDialog.setMessage("Loding Time Table....");
progressDialog.setIndeterminate(false);
progressDialog.setCancelable(false);
progressDialog.show();
}
#Override
protected void onPostExecute(DetailsTimeTable result) {
// TODO Auto-generated method stub
// Log.d("POST DATA", result.getFirst());
progressDialog.dismiss();
if (SSTCTimeTableTabActivity.ram == 1) {
AlertDialog.Builder builder = new AlertDialog.Builder(Monday_Time.this);
builder.setMessage("Time Table is not availble....")
.setCancelable(false)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// do things
startActivity(new Intent(Monday_Time.this, com.src.sstctimetable.MainActivity.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP));
}
});
AlertDialog alert = builder.create();
alert.show();
} else {
itemsList.add("1:: " + result.getFirst());
itemsList.add("2:: " + result.getSecond());
itemsList.add("3:: " + result.getThird());
itemsList.add("4:: " + result.getFourth());
itemsList.add("5:: " + result.getFifth());
itemsList.add("6:: " + result.getSixth());
itemsList.add("7:: " + result.getSeventh());
setListAdapter(new ArrayAdapter<String>(getApplicationContext(), R.layout.rowlayout, R.id.label, itemsList));
}
super.onPostExecute(result);
}
#Override
protected DetailsTimeTable doInBackground(String... params) {
DetailsTimeTable userDetail = null;
RestAPI api = new RestAPI();
try {
JSONObject jsonObj = api.GetTimeTableDetails(params[0], params[1], params[2], params[3]);
JSONParser parser = new JSONParser();
userDetail = parser.parseUserDetails(jsonObj);
} catch (Exception e) {
// TODO Auto-generated catch block
Log.d("AsyncUserDetails", e.getMessage());
}
return userDetail;
}
}
}

catch (Exception e) {
// TODO Auto-generated catch block
// Log.d("AsyncUserDetails", e.getMessage());
}
Try to comment Log print. I think e.getmessage() throwing NullPointerException.

Android AlertDialog freezes when saving data in database

In my App my I am using AlertDialog in Async. But it freezes at a point when data is saving in database. what can I do to keep it running? It runs perfectly for sometime but stops after certain time when database is accessed.
Here's my code:
class BackGroundTasks extends AsyncTask<String, String, Void> {
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
if (dialog == null) {
dialog = ProgressDialog.show(mActivity, null,
"Please wait ...", true);
}
}
#Override
protected Void doInBackground(String... params) {
// TODO Auto-generated method stub
CheckInternetConnection internet = new CheckInternetConnection(
mActivity);
if (!internet.HaveNetworkConnection()) {
return null;
}
return null;
}
protected void onPostExecute(Void result) {
super.onPostExecute(result);
try {
CheckInternetConnection internet = new CheckInternetConnection(
getApplicationContext());
if (!internet.HaveNetworkConnection()) {
showToast("No Internet Connection.");
return;
} else {
setUpdatedBarcodes();
}
}
}
}
private boolean setUpdatedBarcodes(
ArrayList<Model_BarcodeDetail> changedBarcodeList2) {
try {
int i = 0;
BarcodeDatabase barcodeDatabase = new
BarcodeDatabase(mActivity);
barcodeDatabase.open();
for (Model_BarcodeDetail model : changedBarcodeList2) {
barcodeDatabase.updateEntry(model, userId);
}
barcodeDatabase.close();
if (RefList1.equals(RefList)) {
if (dialog != null) {
dialog.dismiss(); // cancelling Async dialog here after
data is saved in DB
}
showToast("Barcodes updated successfully");
}
} catch (Exception e) {
Log.i("Exception caught in: ", "setDownloadedBarcodes method");
e.printStackTrace();
return false;
}
return true;
}

DB operations should be done in the background thread. Put it in doInBackground() method too.

I modify your code. may it helps..
class BackGroundTasks extends AsyncTask<String, String, Void> {
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
if (dialog == null) {
dialog = ProgressDialog.show(mActivity, null,
"Please wait ...", true);
}
}
#Override
protected Void doInBackground(String... params) {
// TODO Auto-generated method stub
CheckInternetConnection internet = new CheckInternetConnection(
mActivity);
if (!internet.HaveNetworkConnection()) {
showToast("No Internet Connection.");
} else {
setUpdatedBarcodes();
}
return null;
}
protected void onPostExecute(Void result) {
super.onPostExecute(result);
if (dialog != null) {
dialog.dismiss(); // cancelling Async dialog here
}
}
}
private boolean setUpdatedBarcodes(
ArrayList<Model_BarcodeDetail> changedBarcodeList2) {
try {
int i = 0;
BarcodeDatabase barcodeDatabase = new
BarcodeDatabase(mActivity);
barcodeDatabase.open();
for (Model_BarcodeDetail model : changedBarcodeList2) {
barcodeDatabase.updateEntry(model, userId);
}
barcodeDatabase.close();
if (RefList1.equals(RefList)) {
showToast("Barcodes updated successfully");
}
} catch (Exception e) {
Log.i("Exception caught in: ", "setDownloadedBarcodes method");
e.printStackTrace();
return false;
}
return true;
}

when saving data in database don't do it on main thread do it on background thread. try code
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
// do your work
}
},0);
or
new Thread(new Runnable() {
public void run() {
// do your work here
}
}).start();

Through this code I am trying to send a value from one Activity to another activity. But I am getting a null value in the other Actvity. In the doinbackground method, I am getting the value of Status and Reason but in onPostexecute I am not getting value. Any idea why?

intent.putExtra("Reason", Reason);
startActivity(intent);
}
else {
Toast.makeText(getApplicationContext(), "Worng", 1000).show();
}
}
}
}

Use this in onCreate() methed on activity class
String Status= getIntent().getExtras().getString("Status");
String Reason= getIntent().getExtras().getString("Reason");

You can use intents,which are messages sent between activities in intent you can put sort data like String, int, etc.
in activity1
Intent intent = new Intent(activity1.this, activity2.class);
intent.putExtra("message", message);
startActivity(intent);
activity2
Intent intent = getIntent();
String message = bundle.getString("message");

onStartCommand Call after Destroying an Activity

i'm observing a weird scenario here. I have a background android service which is running perfectly. but when I kill the process or application from my RecentApps my Application calls the onStartCommand method again. I don't know where I went wrong. I have searched alot but didn't find any appropriate solution. Could someone please mention what I did wrong? Thanks in Advance

here in the logcat the last line shows that its call the onstartcommand method again. Why is it so? Even my Activity is not running I meant to say (the service starts in oncreate method on on acticity, but here in the logcat the control goes directly to the onStartCommand when i destroy my App ).

Your service will be START_STICKY so the android framework is restarting it -> This will give you call to onStartCommand()
I changed my service to START_NOT_STICKY so the android framework will not restart my service on its own without any explicit request from out application
To make your service of START_NOT_STICKY, just return value Service.START_NOT_STICKY from onStartCommand()
This worked and solved my issue

Closed 10 years ago.
I have a custom list view that is getting data from server and changing its content after each 3 seconds.this list view i am using for showing the visitor list who are visiting the site.Each row of list contains ipaddress,statustext,duration time,noofvisit and button text and data is updating and changing in list this part is working fine.For showing this list i am writing custom adapter for this.
Actually i have an issue i have to show the row on the top if status text is chat request.How can i do this?can anyone help me?
Actually i am using tabhost after login screen tabhost contains four tabs.First used for monitoring window that show list of visitor and other are chat window,operatorlist and controls.
As i define above if i got status chat request then that row should appear on the top and will contains two button Accept and deny and on accept button click a window will open for chat and deny will use for refusing chat.
Can anyone help me for solving this issue?

ArrayList<String> userList = your list of data
// other list also
//userListA
//userListB
ArrayList<String> tempUserList = new ArrayList<String>();
// other list also
//tempuserListA
//tempuserListB
String text = "ChatRequest";
// to add CharRequest at top
for(int i=0;i<userList.size();i++)
{
if(userList.get(i).equals(text))
{
tempUserList.add(userList.get(i));
//tempuserlistA.add(userlistA.get(i));
//tempuserlistB.add(userlistB.get(i));
}
}
// to add other entry
for(int i=0;i<userList.size();i++)
{
if(!userList.get(i).equals(text))
{
tempUserList.add(userList.get(i));
//tempuserlistA.add(userlistA.get(i));
//tempuserlistB.add(userlistB.get(i));
}
}
//now temp list are you original list to use
userList = tempUserList;
//userListA = tempuserlistA;
//userListB = tempuserlistB;
// and then call your adapter with the arraylists

You can use an ArrayList holding your Data for the ListView and add an item at the beginning of the list by: myArrayList.add(0, newItem).
Below an example Adapter which can do this:
public class PlaylistAdapter extends BaseAdapter {
private Context context;
private List<Playlist> entries;
public PlaylistAdapter(Context context, List<Playlist> entries) {
this.context = context;
this.entries = entries;
}
public void add(Playlist item) {
if (entries.contains(item))
return;
entries.add(item);
this.notifyDataSetChanged();
}
public void add(int index, Playlist item) {
if (entries.contains(item))
return;
entries.add(index, item);
this.notifyDataSetChanged();
}
#Override
public int getCount() {
return entries.size();
}
#Override
public Playlist getItem(int arg0) {
return entries.get(arg0);
}
#Override
public long getItemId(int arg0) {
return arg0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate the layout you want to use for a single entry row
convertView = inflater.inflate(R.layout.playlists_adapter_entry,
null);
}
// fetches the current item
Playlist playlist = getItem(position);
// fill the entry layout with data
ImageView cover = (ImageView) convertView
.findViewById(R.id.playlist_adapter_entry_cover);
cover.setImageBitmap(playlist.getCover());
TextView title = (TextView) convertView
.findViewById(R.id.playlist_adapter_entry_title);
title.setText(playlist.getTitle());
return convertView;
}
}

How to put custom listview row that has specific text on the top row in listview in android

I have a custom list view that is getting data from server and changing its content after each 3 seconds.this list view i am using for showing the visitor list who are visiting the site.Each row of list contains ipaddress,statustext,duration time,noofvisit and button text and data is updating and changing in list this part is working fine.
Actually i have an issue i have to the row on the top as first row of listview if status text is chat request.How can i do this?can anyone help me?
Actually i am using tabhost after login screen tabhost contains for tab one for monitoring window that show list of visitor and other are chat window,operatorlist and controls.
As i define above if i got status chat request then that row should appear on the top and will contains two button Accept and deny and on accept button click a window will open for chat and deny will use for refusing chat.
Can anyone help me for solving this issue?

what can i do for setting the row that has chat request on the top?Can anyone help me?

Create you customListItem with visibility set to View.GONE by default. When you have a chat request, then just change its visibility to View.VISIBLE and refresh your list. Simple.

If you want to add some view as the first row of your listview, then use
listview.addHeaderView(myHeaderView);
use this before setting list adapter.

try like this..
boolean bool=true;
new Thread(new Runnable() {
public void run() {
while(bool){
int t=StatusText.IndexOf(chat)
if(t!=-1)
{
Collections.swap(StatusText,0,t);
Collections.swap(SessionText,0,t);
Collections.swap(IPText,0,t);
Collections.swap(DurationText,0,t);
Collections.swap( NoOfVisit ,0,t);
Collections.swap(ButtonText,0,t);
}
runOnUiThread(new Runnable() {
public void run() {
adapter.notifyDataSetChanged();
}
});
