The most common cause of this problem is a NullPointerException at runtime.
Steps to follow:
Observe the Stack trace on Android Studio as shown below:
You can then analyze the Stack trace, and zero in on what exactly caused the exception, and the line that caused it. Alternatively, you can post the screenshot of your stack trace so it can be easier to answer the question.

Use findViewById inside onCreate and use Double.parse only after values have been entered in the edittexts.
Try this code:
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText number1 = (EditText) findViewById(R.id.number1);
final EditText number2 = (EditText) findViewById(R.id.number2);
Button add = (Button) findViewById(R.id.btnAdd);
Button sub = (Button) findViewById(R.id.btnSub);
Button div = (Button) findViewById(R.id.btnDiv);
Button mul = (Button) findViewById(R.id.btnMul);
final TextView txtresult = (TextView) findViewById(R.id.result);
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
double num1, num2, result;
num1 = Double.parseDouble(number1.getText().toString());
num2 = Double.parseDouble(number2.getText().toString());
result = num1 + num2;
txtresult.setText(Double.toString(result));
}
});
sub.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
double num1, num2, result;
num1 = Double.parseDouble(number1.getText().toString());
num2 = Double.parseDouble(number2.getText().toString());
result = num1 - num2;
txtresult.setText(Double.toString(result));
}
});
div.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
double num1, num2, result;
num1 = Double.parseDouble(number1.getText().toString());
num2 = Double.parseDouble(number2.getText().toString());
result = num1 / num2;
txtresult.setText(Double.toString(result));
}
});
mul.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
double num1, num2, result;
num1 = Double.parseDouble(number1.getText().toString());
num2 = Double.parseDouble(number2.getText().toString());
result = num1 * num2;
txtresult.setText(Double.toString(result));
}
});
}

Retrofit error in Android

I am trying to create a login page. Onclick of the button, I am calling a method to verify the login credentials if already present in the backend django server. I am able to fetch the values of the username and password. The problem that I am currently facing is, if I give the login credentials already present in the backend server, the application works fine. But if I give login credentials which are not in the backend database, the application crashes. Kindly help

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.

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);

Getting NullPointerException in code which was working earlier

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 {

getPnr.setOnClickListener(this);
pnrClear.setOnClickListener(this);
}

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);

You only create values for maximum[0] and maximum[1], same for minimum.
So when you call
JSONObject j4 = new JSONObject(minimum[2]);
you pass null to the JSONObject.
