Progress Dialog, Broadcast receiver crash in android

I have been trying for a long time to work on a button onClick listener that performs the following
launch a loading screen (progress bar).
Send an sms msg in the background to a specific number.
wait for the reply using broadcast listener, which is a message containing a link.
dismiss the loading screen.
then take this link and use it to start another activity.
The code shows no errors, however each time I press the button it doesn't show the progress bar, it only sends a message then waits for the specified time then crashes.
Here's the code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener(){
#Override
`public void onClick(View arg0) {
// TODO Auto-generated method stub
new LoadTracker().execute();
}});
}
protected void sendSMS() {
// TODO Auto-generated method stub
String Phoneno = "***********";
String Message = "www.google.com";
SmsManager manager= SmsManager.getDefault();
manager.sendTextMessage(Phoneno, null, Message, null, null);
}
private BroadcastReceiver Receiver = new BroadcastReceiver(){
public static final String SMS_BUNDLE = "pdus";
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Bundle intentExtras = intent.getExtras();
if (intentExtras != null) {
Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
for (int i = 0; i < sms.length; ++i) {
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);
String smsBody = smsMessage.getMessageBody().toString();
Intent in = new Intent(Intent.ACTION_VIEW, Uri.parse(smsBody));
startActivity(in);
}
}
}};
private class LoadTracker extends AsyncTask<Void, Integer, Void>{
protected void onPreExecute(){
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setTitle("Sending Signal");
progressDialog.setMessage("Receiving Signal, Please Wait");
progressDialog.setCancelable(false);
progressDialog.setIndeterminate(false);
progressDialog.setMax(100);
progressDialog.setProgress(0);
progressDialog.show();
}
#Override
protected Void doInBackground(Void... params) {
// TODO Auto-generated method stub
try{
synchronized (this){
IntentFilter IF = new IntentFilter("android.provider.Telephony.SMS_RECEIVED");
sendSMS();
registerReceiver(Receiver,IF);
this.wait(10000);
this.wait(10000);
publishProgress(100);
}
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
protected void onProgressUpdate(Integer... values){
progressDialog.setProgress(values[0]);
}
#Override
protected void onPostExecute(Void result)
{
//close the progress dialog
progressDialog.dismiss();
//initialize the View
setContentView(R.layout.activity_main);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(Receiver);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Note: The Phone number belongs to the phone on which the application is running so it should open google after it receives the reply
All the uses permissions are in place too.
Update: I discovered the problem with the progress dialog, the "O" letter in OnPreExecute Should've been lower case. Now the progress Dialog appears and the app sends the message however, the app crashes as soon as the reply sms message is received. How can I solve this?

Not sure but from the following line
ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=www.google.com ...
I think your URL should be like http://www.google.com. Its missing the protocol http without which it might not recognize the right activity to handle the Intent.

How can this problem be fixed and what can be done in the future to prevent this?
Also why does this happen.

from the looks of is either res is null or something's null within these lines
if (Integer.parseInt(res) == 1) {
publishProgress(1);
// user successfully registred
// Store user details in SQLite Database
DatabaseHandler db = new DatabaseHandler(
getApplicationContext());
JSONObject json_user = json.getJSONObject("user");
However its hard to be sure. publishProgress or getApplicationContext may have something throwing the NullPointerException as well. Try this for debugging the problem : since you're using eclipse, you can use debugger instead of println, its way more powerful. A useful tutorial. If you don't want to use the debugger, print the values instead of numbers. They'll provide much more useeful context.

You must check activity isFinishing() If the activity is finishing, returns true; else returns false.

Android ListView with 2 TextViews and 1 Button

I'm trying to create a ListView with 2 TextViews and 1 Button. When the users click in the button the activity will finish(); and pass the result to another view. I followed this tutorial . But for some reason when i click to start that activity my application crashes! Here is the 3 files from my app that are relevant.
List Structure Data:
public class formulasListData {
private String formulasName;
private String formulasDefinition;
public formulasListData(String formulasName, String formulasDefinition) {
super();
this.formulasName = formulasName;
this.formulasDefinition = formulasDefinition;
}
public String getFormulasName() {
return formulasName;
}
public void setFormulasName(String formulasName) {
this.formulasName = formulasName;
}
public String getFormulasDefinition() {
return formulasDefinition;
}
public void setFormulasDefinition(String formulasDefinition) {
this.formulasDefinition = formulasDefinition;
}
}
The List Adapter:
public class formulasListAdapter extends BaseAdapter implements OnClickListener {
private Context context;
private List<formulasListData> formulasList;
public formulasListAdapter(Context context, List<formulasListData> formulasList) {
this.context = context;
this.formulasList = formulasList;
}
#Override
public int getCount() {
return formulasList.size();
}
#Override
public Object getItem(int position) {
return formulasList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View rowView, ViewGroup parent) {
formulasListData entry = formulasList.get(position);
if(rowView == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.formulas_row, null);
}
TextView formulasName = (TextView) rowView.findViewById(R.id.formulas_name);
formulasName.setText(entry.getFormulasName());
TextView formulasDefinition = (TextView) rowView.findViewById(R.id.formulas_definition);
formulasDefinition.setText(entry.getFormulasDefinition());
Button btnSelect = (Button) rowView.findViewById(R.id.selectFormula);
btnSelect.setFocusableInTouchMode(false);
btnSelect.setFocusable(false);
btnSelect.setOnClickListener(this);
btnSelect.setTag(entry);
return rowView;
}
#Override
public void onClick(View view) {
formulasListData entry = (formulasListData) view.getTag();
}
}
And the activity that should display the list.
public class FormulasList extends Activity {
private static final int FORMULA_0 = 0;
private static final int FORMULA_1 = 1;
private static final int FORMULA_2 = 2;
private static final int FORMULA_3 = 3;
private static final int FORMULA_4 = 4;
private static final int FORMULA_5 = 5;
private static final int FORMULA_6 = 6;
// private static final int FORMULA_7 = 7;
public void onCreate(Bundle savedInstance) {
super.onCreate(savedInstance);
ListView formulasListView = (ListView) findViewById(R.id.formulas_list);
formulasListView.setClickable(true);
final List<formulasListData> formulasList = new ArrayList<formulasListData>();
final String[] formulasName = new String[] {"Circunference of a Circle:",
"Area of a Circle:",
"Volume of a Sphere:",
"Area Triangle:",
"Area Square:",
"Volume of a Cube:",
"Pithagorean Theorem:"};
final String[] formulasDefinition = new String[] {"2 × π × r",
"π × r²",
"(4/3) × π × r³",
"(b × h)/2",
"side²",
"side³",
"a² + b² = c²"};
// formulasList.add(new formulasListData(formulasName, formulasDefinition));
formulasList.add(new formulasListData(formulasName[0], formulasDefinition[0]));
formulasList.add(new formulasListData(formulasName[1], formulasDefinition[1]));
formulasList.add(new formulasListData(formulasName[2], formulasDefinition[2]));
formulasList.add(new formulasListData(formulasName[3], formulasDefinition[3]));
formulasList.add(new formulasListData(formulasName[4], formulasDefinition[4]));
formulasList.add(new formulasListData(formulasName[5], formulasDefinition[5]));
formulasList.add(new formulasListData(formulasName[6], formulasDefinition[6]));
SharedPreferences settings = getSharedPreferences(SettingsActivity.PREF_NAME, MODE_PRIVATE);
SettingsActivity.newTheme = settings.getInt("themeCustom", 0);
if(SettingsActivity.newTheme == SettingsActivity.THEME_DARK) {
setTheme(R.style.DarkTheme);
} else if(SettingsActivity.newTheme == SettingsActivity.THEME_LIGHT){
setTheme(R.style.LightTheme);
} else if(SettingsActivity.newTheme == SettingsActivity.THEME_COLORS) {
setTheme(R.style.ColorsTheme);
} else {
setTheme(R.style.AppTheme);
}
setContentView(R.layout.activity_formulas);
formulasListAdapter adapter = new formulasListAdapter(this, formulasList);
formulasListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,long index) {
Intent intent= getIntent();
Bundle b = new Bundle();
switch (position) {
case FORMULA_0:
b.putString("key0", formulasDefinition[0]);
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_1:

intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_2:

intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_3:
b.putString("key0", formulasDefinition[3]);
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_4:
b.putString("key0", formulasDefinition[4]);
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_5:
b.putString("key0", formulasDefinition[5]);
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;
case FORMULA_6:
b.putString("key0", formulasDefinition[6]);
intent.putExtras(b);
setResult(RESULT_OK, intent);
finish();
break;

}
}
});
formulasListView.setAdapter(adapter);
}
}

Try moving
setContentView(R.layout.activity_formulas);
To the start of the method. Right after the super call.
You are trying to use gui controls before initializing the activity layout
