Unfortunately, FindWorkOutActivity has stopped working. How to solve this error?

I am new in Android Learning and try to complete my task, in which i need to create the Workout simple app, with dropdown, button and text. In app preview, app is looking fine but when i run on device it gives me an error "Unfortunately, FindWorkOutActivity has stopped working."
I have searched on internet about this error and unable to understand the Logcat information as i didn't learn about this. Kindly help me to solve this error.
Below are the Files of my app:

FindWorkOutActivity.java
package com.example.rj.findworkout;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Spinner;
import android.widget.TextView;
/**

*/
public class FindWorkOutActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_find_work_out);
}
public void onClickWorkOut(View view){
TextView workouts = (TextView) findViewById(R.id.text_hello);
Spinner workouttype = (Spinner) findViewById(R.id.spinner_id);
String workout = String.valueOf(workouttype.getSelectedItem());
workouts.setText(workout);
}
}

Your problem is the onClick property in the Spinner. The proper way is to add setOnItemSelectedListener on it instead. So first you need to remove the
android:onClick="onClickWorkOut"
and in the Activity code, add a OnItemClickListener instead.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Spinner workouttype = (Spinner) findViewById(R.id.spinner_id);
workouttype.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
}

Spinner not showing selected or default choice

I've created a spinner that takes some user-generated strings (in my case classes - the school type) and displays them in a typical spinner way. My problem occurs when trying to select an item from the spinner. I can tap on the spinner and select the class, but the spinner never shows that I have the class selected. Before adding user-generated strings, I had a string-array xml file that worked perfectly.
I've tried adding notifyDataSetChanged() at the end of the onCreate() method, created a spinner layout with a transparent background and black text, and setting an setOnItemSelectedListener(). None of these worked, so I reverted code back to original state.

I'm wondering if there is a way to fix this and have the spinner display the default / user choice. If you need any more of the code, all of it can be found in the GitHub. Thanks in advance for all answers!

Solution: Try loading the classes prior to starting the activity, for example in the MainActivity. Then pass the values along through an intent.
Example:
MainActivty.java
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Launch Add Homework Activity
Intent intent = new Intent(MainActivity.this, addAssignment.class);
intent.putExtra("classListNames", classListNames);
startActivity(intent);
...
classDb.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
classList.clear();
for (DataSnapshot userSnapshot: dataSnapshot.getChildren()) {
Classes mClass = userSnapshot.getValue(Classes.class);
Log.i(TAG, "Class loaded: " + mClass.getClassName());
classList.add(mClass);
classListNames.add(mClass.getClassName());
}
}
#Override
public void onCancelled(DatabaseError databaseError) {
Log.e(TAG, "Error: " + databaseError.getMessage());
}
});
addAssignment.java
// Gets class list
Bundle extras = getIntent().getExtras();
classListNames = extras.getStringArrayList("classListNames");
...
mDueClass = (Spinner) findViewById(R.id.class_spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.spinner_layout, classListNames);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mDueClass.setAdapter(adapter);
Cause: After some debugging, I discovered the cause of the problem to be timing differences. The app would request the classes be sent, create the spinner, then load the classes. The difference in timing was milliseconds, but just enough to cause the problem.

Why is Android closing the application without showing the "<application> has stopped unexpectedly" message?

I am in the process of learning Android development and was trying to crash my application at runtime. I made a button that calls a method when clicked and then made sure that the method does not exist.
The application starts up fine. As soon as i click the button, the application closes just as intended. The only unexpected thing was that my device did not show any error message like application has closed unexpectedly or that the application force closed.
Did I accidentally turn off some setting in the Developer Options or is it just my device that doesn't like showing error messages ? Any more information needed ?

It's based on this Udacity course.

In your XML button, its submitOrder not submitOrders. See the extra S :
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAllCaps="true"
android:text="ORDER"
android:onClick="submitOrder"/>
So, change this:
public void submitOrders(View view) {
With this:
public void submitOrder(View view) {

Remove s from method name submitOrders
public void submitOrder(View view) {
int quantity = 5 ;
display(quantity) ;
displayPrice(quantity * 50) ;
}
Or You can remove android:onClick="submitOrder"
<Button
android:id="#+id/order"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAllCaps="true"
android:text="ORDER"/>
than in your java file
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button order = (Button)findViewById(R.id.order);
order.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int quantity = 5 ;
display(quantity) ;
displayPrice(quantity * 50) ;
}
});
}

The problem is when i run the app, the button does nothing, but if i change the button Onclick for
tvRegistrarGo.setText("Prueba");
the button works! I'm working with:
this sdk version and this build tools version
This is the logcat i get when i pressed one hundred times the button, but if i press once the edit text with the onclick it appears on the logcat:

The problem is that you are reading the values of your EditTexts before the user has a chance to enter them.
Change this:
final String email = etEmail.getText().toString();
final String pass = etPassL.getText().toString();
btLoginL.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EnviarDatos(email, pass);
}
to this
btLoginL.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EnviarDatos(
etEmail.getText().toString(),
etPassL.getText().toString() );
}

Sending contact form in android via email

I am trying to make a basic contact form app where people can fill in the needed information and press the send button and have the information sent to a specific E-mail. I have put it together but for some reason it is not working. The Java file has code in it from a similar app. The Java file has spinner code in it so I turned it into notes.. not sure if it's messing something up. Here is the code please let me know what I can do to make it work.

I have the form appearing now but the information that you input is not getting sent to the email. I am getting prompted to a screen indication which email service i should use to execute this app. I just want the information entered to be directly sent to the email that is provided in the app.
Thanks in advance!

You're seeing that screen with the list of email clients because that's how Intents work.
An intent won't directly execute the action you want it to, all it can do is hand off the data to another Activity (perhaps in a different application) that can handle the data.
