Connection Loss Handling in AsyncTask in 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.

Error with passing data into intent

I've been doing an application which requires user inputs. This is my code:
UserInput.java
public class UserInput extends Activity
{
String tag = "UserInput";
EditText userInput;
Uri rResult = null;
int request_Code = 1;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.userinput);
Button btn= (Button) findViewById(R.id.btnSubmit);
Button saveButton = (Button) findViewById(R.id.btnSave);
saveButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v){
Intent intent = new Intent("com.example.Summary");
Bundle extras = new Bundle();
extras.putString("amount", userInput.getText().toString());
intent.putExtras(extras);
startActivityForResult(intent, request_Code);
}
});
}
protected void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
}
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
saveAsText();
Log.d(tag, "In the onPause() event");
}
protected void onRestart() {
// TODO Auto-generated method stub
super.onRestart();
}
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
retrieveText();
Log.d(tag, "In the onResume() event");
}
protected void onStart() {

}
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
}
public void saveAsText() {
String line = userInput.getText().toString();
if (rResult != null)
line += "|" + rResult;

BufferedWriter bw = null;
PrintWriter pw = null;
try {
String path = Environment.getExternalStorageDirectory().getPath();
fw = new FileWriter(path + "/UserInput.txt");
bw = new BufferedWriter(fw);
pw = new PrintWriter(bw);
pw.println(line);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (pw != null)
pw.close();
if (bw != null)
bw.close();
if (fw != null)
fw.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}// saveAsText
public void retrieveText() {
FileReader fr = null;
BufferedReader br = null;
try {
String line;
String path = Environment.getExternalStorageDirectory().getPath();
fr = new FileReader(path + "/UserInput.txt");
br = new BufferedReader(fr);
line = br.readLine();
StringTokenizer st = new StringTokenizer(line, "|");

if (fr != null)

} catch (Exception e) {
e.printStackTrace();
}
}
}
}
Here is my Summary Page:
public class Summary extends Activity
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.summary);
Bundle bundle = getIntent().getExtras();
int amount = Integer.parseInt(bundle.getString("amount"));
TextView resultView = (TextView) findViewById(R.id.retrieveInput);
resultView.setText(amount);
}
When I run using these codes, it still runs, but when I click the User Input button, it crashed. May I know what went wrong and what I can do so that it runs perfectly? Thanks!
Logcat

When you create an Intent with the String constructor, you are actually setting the Intent's action. What you want is intent = new Intent(UserInput.this, Summary.class). Also make sure that the Summary activity is registered in your manifest.

userInput, did you initiate that edit text? when you don't initiate. Its starting value is null. In that onclick, you're getting that null pointer exception bc you're trying to dereference that null object

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

how to make a view visible from customAdapter's textView's ClickEvent in android?

I have made an activity In that I am having three relative Layouts and i am making them visible and gone as per needed.Now I have one ListView Called BuyingRequestList and for that i have made customeAdapter ,Now I have put a clickEvent of CustomAdapter's textView,Now what i need is when I click on the ListItem's textView "Quote" one relative layout "quote_view" is only visible and other two layouts should be invisible,My code is as below:

Create an interface class, say ViewHider
public interface ViewHider{
public void hideView(String clickedtext);
}
have your activity implement this.
In your activity add unimplemented method and write inside it like
#Override
public void hideView(String clickedtext) {
if(clickedtext.equals("Quote"){
layoutName.setVisibility(View.GONE);
}
}
In your adapter, create an object of ViewHider class
ViewHider viewHider;
then, set click listener for the text view you want and inside that call the method
if(textView.getText.equals("Quote")
viewHider.hideView("Quote");

Loading Progress Bar android

*I have class which load some files and update the UI...It takes some times to view the result,... So I want to add a loading bar or progress bar.

So I want to add a loading bar or progress bar
For your approach you need to use Threads. Especially i recommend to you have look at
Handler
AsyncTask
Both approaches offer work with Threads. AsyncTask is more complex than Handler also it's generic-type so offer more type-safe and faster work.
You should read some tutorials so
ProgressBar updating using Message Handler
Create A Custom Progress Bar Using
AsyncTask
And there is very awesome and useful tutorial at Vogella
Android Threads, Handlers and AsyncTask -
Tutorial

I would look at using AsyncTask. Here is a link that should help you get started: http://developer.android.com/reference/android/os/AsyncTask.html

The way you're going to want to do this is within an ASyncTask that has callbacks for updating a progress bar. I've included a sample below that doesn't actually do anything. You'd put your code for calling the download in doInBackground() and update the progress from onProgressUpdate.
public class BackgroundAsyncTask extends
AsyncTask<Void, Integer, Void> {
int myProgress;
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
Toast.makeText(AndroidAsyncTaskProgressBar.this,
"onPostExecute", Toast.LENGTH_LONG).show();
}
#Override
protected void onPreExecute() {
// TODO Auto-generated method stub
Toast.makeText(AndroidAsyncTaskProgressBar.this,
"onPreExecute", Toast.LENGTH_LONG).show();
myProgress = 0;
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
while(myProgress<100){
myProgress++;
publishProgress(myProgress);
SystemClock.sleep(100);
}
return null;
}
#Override
protected void onProgressUpdate(Integer... values) {
// TODO Auto-generated method stub
progressBar.setProgress(values[0]);
}
}
