Getting NullPointerException in code which was working earlier - java

I have a code to check PNR number. Because of internet issues, i thought to give users to check PNR by SMS. So I added 2 Radio Buttons, one for internet and one for SMS. But the problem is now when I click the PNR Button, it gives nullPointer Exception.
Here is my Main Activity.java
public class MainActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
private EditText pnrNumber;
private TextView errMsg;
private Button getPnr;
private Button pnrClear;
Button Yes, No;
RadioButton checkbyinternet, checkbysms;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
errMsg = (TextView) findViewById(R.id.errMsg);
pnrNumber = (EditText) findViewById(R.id.pnrNumber_p01);
getPnr = (Button) findViewById(R.id.checkPNRButton);
pnrClear = (Button) findViewById(R.id.pnrClear);
getPnr.setOnClickListener(this);
pnrClear.setOnClickListener(this);
}
public void onClick(View src) {
// Perform action on click
if (src.getId() == R.id.checkPNRButton)
{
if (checkbyinternet.isChecked())
{
int pnr2 = pnrNumber.getEditableText().length();
if (pnr2 != 10)
{
errMsg.setText("Length of PNR is Invalid.");
}
else
{
String pnr = pnrNumber.getEditableText().toString();
Bundle b = new Bundle();
b.putString("pnr", pnr);
System.out.println("Connectivity : "
+ this.isNetworkAvailable());
PNRStatus pnrStatus = null;
// Connect to the Server and Get the PNR status
try
{
String captcha = "37819";
String pnr1 = pnrNumber.getText().toString();
String reqStr = "lccp_pnrno1=" + pnr1
+ "&lccp_cap_val=" + captcha
+ "&lccp_capinp_val=" + captcha
+ "&submitpnr=Get+Status";
PNRStatusCheck check = new PNRStatusCheck();
StringBuffer data = check
.getPNRResponse(reqStr,
"http://www.indianrail.gov.in/cgi_bin/inet_pnstat_cgi_28688.cgi");
// String pnr1 = pnr; //"1154177041";
// String reqStr = "lccp_pnrno1=" + pnr1 +
// "&submitpnr=Get+Status";
// PNRStatusCheck check = new PNRStatusCheck();
// StringBuffer data = check.getPNRResponse(reqStr,
// "http://www.indianrail.gov.in/cgi_bin/inet_pnrstat_cgi.cgi");
if (data != null)
{
pnrStatus = check.parseHtml(data);
b.putSerializable("pnrStatus", pnrStatus);
}
else
{
// error
}
}
catch (Exception e)
{
e.printStackTrace();
}
Intent to = null;
if (pnrStatus != null)
{
to = new Intent(this, PNRStatusActivity.class);
to.putExtras(b);
startActivity(to);
}
else
{
errMsg.setText("Error prcessing PNR. Please try again.");
}
}
}
else if (checkbysms.isChecked())
{
// Toast.makeText(this, "SMS", Toast.LENGTH_SHORT).show();
int pnr2 = pnrNumber.getEditableText().length();
if (pnr2 != 10)
{
errMsg.setText("Length of PNR is Invalid.");
}
else
{
openSMSWarningDialog(src);
}
}
}
else if (src.getId() == R.id.pnrClear)
{
errMsg.setText("");
pnrNumber.setText("");
}
}
public boolean isNetworkAvailable() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = cm.getActiveNetworkInfo();
// if no network is available networkInfo will be null, otherwise check
// if we are connected
if (networkInfo != null && networkInfo.isConnected()) {
return true;
}
return false;
}
public void openSMSWarningDialog(View view) {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.setContentView(R.layout.smsdialog);
dialog.setTitle("Are you sure to use SMS.?");
Yes = (Button) dialog.findViewById(R.id.yes);
No = (Button) dialog.findViewById(R.id.no);
Yes.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String PnrNum = pnrNumber.getText().toString();
String messageToSend = ("PNR " + PnrNum);
String number = "139";
SmsManager.getDefault().sendTextMessage(number, null,
messageToSend, null, null);
dialog.dismiss();
Toast.makeText(
getBaseContext(),
"Please check your inbox in sometime for your PNR Status",
Toast.LENGTH_LONG).show();
}
});
No.setOnClickListener(new View.OnClickListener() {
#Override

// TODO Auto-generated method stub
dialog.dismiss();

dialog.show();
}
}

Please help, I am not able to get any solution for this.

Your checkbyinternet and checkbysms buttons are uninitialized and that is why you're getting the NullPointerException when if (checkbyinternet.isChecked()) is executed in the onClick() method.
if (src.getId() == R.id.checkPNRButton) // true if you pressed the getPnr button
{
if (checkbyinternet.isChecked()) // checkbyinternet is uninitialized yet, so it'll throw a NPE
You need to initialize them as well in the onCreate() method.
checkbyinternet = (RadioButton) findViewById(R.id.internet);
checkbysms = (RadioButton) findViewById(R.id.sms);

How to fix java.lang.IllegalStateException: Could not execute method for android:onClick

I am a newbie trying to create a simple quiz app in Android Studio. Things were progressing reasonably well until I tried to create an onClick event for a radiogroup.
I took a look at this previously answered question: java.lang.IllegalStateException: Could not execute method for android:onClick Android App but the solution did not shed any light on my issue.
Another thing I noticed was a problem with the imported AppCompatViewInflater.java WHICH 'cannot resolve symbol 'R''?
Any advice would much appreciated.
This is the logcat error message that I see:

Call another activity from button on camera Android

I'm implementing a Camera app on Android, I'd like to have a button on it which will lead the user to the developer website, or my website.
This button is placed right of the shutter button.
I was trying to call the webview activity from this button, but it's giving me errors and I'm confused on this case, because there are plenty of examples of calling an activity inside another one, but no from a camera app.
I don't know what am I doing wrong.
Here's the piece of code in MainActivity:
public class MainActivity extends Activity /**implements OnClickListener**/ {
ImageView image;
Activity context;
Preview preview;
Camera camera;
Button exitButton;
ImageView fotoButton;
Button webButton;
LinearLayout progressLayout;
String path = "/sdcard/KutCamera/cache/images/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context=this;
webButton = (Button) findViewById(R.id.imageView_world);
fotoButton = (ImageView) findViewById(R.id.imageView_foto);
exitButton = (Button) findViewById(R.id.button_exit);
image = (ImageView) findViewById(R.id.imageView_photo);
progressLayout = (LinearLayout) findViewById(R.id.progress_layout);
preview = new Preview(this,
(SurfaceView) findViewById(R.id.KutCameraFragment));
FrameLayout frame = (FrameLayout) findViewById(R.id.preview);
frame.addView(preview);
preview.setKeepScreenOn(true);
fotoButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
takeFocusedPicture();
} catch (Exception e) {
}
exitButton.setClickable(false);
fotoButton.setClickable(false);
webButton.setClickable(true);
progressLayout.setVisibility(View.VISIBLE);
}
});
webButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(MainActivity.this, WebActivity.class);
MainActivity.this.startActivity(myIntent);
}
});
}
Everytime I run it it throws me this error:
4-04 00:33:43.929 4237-4237/com.kut.kutcamera E/AndroidRuntime﹕ FATAL EXCEPTION: main

The layout declaration of the world button is just Okay, I don't really think it's because of that, I guess there is something inside that camera method that doesn't allows me to properly make the call.
Can anybody shed some light on this?
Thanks in advance!

Thank you

TextView cannot be cast to SeekBar

I am experiencing issues relating my textview to my seekbar, and have received the below message as such. I am under the premises that it was due for the following reasons: 1) Trying to store the seekbar values information recorded by the user into parse to be able to retrieve it later. Storing the EditText such as name, age, headline and radiobox such as gender works fine, but its when I include the seek that the application fails to run.
I have tried doing a project clean, and rewording ID with the "right prefix" such as sb for seekbar, and tv for textview.
Below is the logcat message:

Your XML has defined tvseekBarDistanceValue as a TextView, not a SeekBar. Since you're trying to change a TextView to a SeekBar (which is impossible), you are getting this error.
Based on your XML, I think you want to replace
seekBarDistance = (SeekBar) findViewById(R.id.tvseekBarDistanceValue);
with
seekBarDistance = (SeekBar) findViewById(R.id.sbseekBarDistance);

What is the problem? Where am I going wrong? How should I populate the spinner?
You should
return view;
instead of
return container;
in your onCreateView(.....) in PlacementFragment
also change this
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(activity,
android.R.layout.simple_spinner_item, items);
to
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(getActivity(),
android.R.layout.simple_spinner_item, items);
Caused by: java.lang.NullPointerException
android.widget.ArrayAdapter.init(ArrayAdapter.java:310)
Apart form the other answer you need to change to
ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>(getActivity(),
android.R.layout.simple_spinner_item, items);
Activity activity; activity is not initialized.
Try this..
You have not initialize Activity activity initialize it as
activity = getActivity();
