ClassCastException android Integer to Long

I was using an integer for the money factor in this little test app but I realized that long was more appropriate and I changed the code so that money is a long instead of an int and I changed SharedPreferences appropriately as well, however it does not work wheras it did when I used int. Thank you for the help!
public class Home extends AppCompatActivity {
SharedPreferences pref;
SharedPreferences.Editor editor;
Intent intent;
TextView home_money_view;
long money; // this is the variable that is causing problems
int initial;
final long TEST = (long)-1;
int gold_pieces;
int gold_price = 50;
TimerTask timerTask;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
home_money_view = (TextView) findViewById(R.id.home_money_view)
pref = getApplicationContext().getSharedPreferences("MY_PREFS", MODE_PRIVATE);
editor = pref.edit();
money = pref.getLong("temp_money",Long.MIN_VALUE); // get value
if (money==Long.MIN_VALUE){
money=0;
}
gold_pieces = pref.getInt("temp_gold",-1);
if (gold_pieces==-1){
gold_pieces=0;
}
initial = pref.getInt("initial",0);
money+=initial;
editor.putInt("initial",0);
editor.commit();
home_money_view = (TextView) findViewById(R.id.home_money_view);
home_money_view.setText(money+"");
editor.commit();
}
public void backToSplash(View view){
intent = new Intent(Home.this,BusinessSelector.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
public void goToSecondView(View view){
long temp_money = money;
editor.putLong("temp_money",temp_money); // set value
int temp_gold = gold_pieces;
editor.putInt("temp_gold",temp_gold);
editor.commit();
intent = new Intent(Home.this,SecondView.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
public void goToOtherView(View view) {
long temp_money = money;
editor.putLong("temp_money",temp_money); // set value
int temp_gold = gold_pieces;
editor.putInt("temp_gold", temp_gold);
editor.commit();
intent = new Intent(Home.this, Next.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
}

All other activities are coded similar to the above.

With just two intents the code worked fine, but when I'm comparing the value with strings, the app crashes, I don't know where the bug is.

Instead of getBaseContext() and getApplicationContext(), use MainActivity.this as context, will work everywhere.

You should put it like this
public class SecondActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
Intent i = getIntent();
}
}
If the extra data are strings you can get it like this:
String nameString = i.getStringExtra("nameExtra");

You can't use getIntent() before onCreate(), there's simply no Intent available at that point.
In your code, I suspect that you are trying to get StringExtras from Intent, But as intent is null, it is throwing NullPointerException.
In your Second Activity you can use getIntent() in onCreate() method.
public class SecondActivity extends Activity {
Intent intent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second_activity);
intent = getIntent();
String userName = intent.getStringExtra("Second");
...
}
}

Use little pieces of code checking, to ensure your intent behaves properly. For example, you could surround your getIntent code with an if statement. For which proper method to call, you have to wander around a bit, as this depends on what you want your app to do. Fortunately, Eclipse delivers you all the related documentation, when you write down some piece of Android resources, e.g. Intent.

This exception is thrown when application tries to access network in main thread. This is forbidden as accessing resources over network may take indefinite amount of time and your main thread will be blocked untill network operation finishes, thus making your app frozen to the user.
Instead in your onClick() method you should start a new AsyncTask which will do the networking. After the task finishes proceed with updating the ui (changing activity etc.).

How to pass get text from userinput (edittext) and put into a textview in another activity?

I would like to take user input entered in the EditTextField(in the EnterNewFile class) and put it into the TextField (in the NoteEdit class). Please help! Thanks! FYI- I use XML files for the layouts of these two classes.

Take the input from Edittext send it through the Intent to your destination activity and then set it in the TextView there.
I think you seem to already be doing that in your code:
The issue might be the you've not defined in your XML that nextButton function should be call on click ( inside android:onClick: inside your Button).
What you can also do is, in your onCreate funcion set up a listener which listens to the button click and call the intent from within it.
final EditText editText = (EditText) findViewById(R.id.file_name_edittext);
mButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
/** Called when the user clicks the Next button */
Log.d("EditText", mText.getText().toString());
Intent intent = new Intent(EnterNewFile.this, NoteEdit.class);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
});
//here you are taking value from EditText and send it to other activity:
Instead of
// Get the message from the intent
Intent intent = getIntent();
String message = intent.getStringExtra(EnterNewFile.EXTRA_MESSAGE);
use following in onCreate() of your other NoteEdit activity:
Intent intent = getIntent();
if((intent.getExtras()!=null) && !intent.getExtras().isEmpty()){
String message = intent.getExtras().getString(EnterNewFile.EXTRA_MESSAGE);
}

this code is working:-
scrollview=(ScrollView)findViewById(R.id.scrollview1);
tb2.setTextSize(30);
tb2.setMovementMethod(new ScrollingMovementMethod());
scrollview.post(new Runnable() {
public void run() {
scrollview.fullScroll(View.FOCUS_DOWN);
}
});
chat1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
{
textsaring1=edt1.getText().toString();
tb2.setText(tb2.getText()+" "+textsaring1);
edt1.setText("");
}
}
});

How to access data in the previous activity?

Using StartActivity i reached SecondActivity from FirstActivity..Now i want to access object declared in the previous activity.
Is there any obvious mechanisms that i am missing.I cant use Parceable on the object(DropboxAPI) i want to pass since i do not have its source(i can't make it parceable).
Can i pass FirstActivity.this since i can make it Parceable using an intent?or like
Intent intent=new Intent(FirstActivity.this,SecondActivity.class);
intent.putExtra("MyClass",FirstActivity.this);
startActivity (intent);
import com.dropbox.client2.DropboxAPI;
import com.dropbox.client2.android.AndroidAuthSession;
import android.app.Application;
import android.hardware.Camera.Parameters;
import android.os.Parcel;
import android.os.Parcelable;
public class temp extends Application {
DropboxAPI<AndroidAuthSession> mApi;
public void onCreate() {
super.onCreate();
}
temp(DropboxAPI<AndroidAuthSession> Api)
{
mApi=Api;
}
public DropboxAPI<AndroidAuthSession> getName() {
return mApi;
}
public void setName(DropboxAPI<AndroidAuthSession> dropboxclient) {
this.mApi = dropboxclient;
}
}
Code in first class:
t = (temp)getApplication();
t.setName(mApi);
//basket.putParcelable("key", MCActivity.this);
Intent intent=new Intent(MCActivity.this,DownActivity.class);
//intent.putExtra("MyClass",t);
startActivity (intent);
Code in Second class:
public void onCreate(Bundle bun) {
// TODO Auto-generated method stub
super.onCreate(bun);
setContentView(R.layout.download);
mImage = (ImageView)findViewById(R.id.image_view);
//Bundle gotit=getIntent().getExtras();
t = (temp)getApplication();
int i=2;
i=5;
dApi=t.getName();
}

try using Application class:
public class MyApplication extends Application {
//Variable we want to share to All Activities in Application
private DropboxClient dropboxclient;
#Override
public void onCreate() {
super.onCreate();
}
//Getter Method
public DropboxClient getName() {
return dropboxclient;
}
//Setter Method
public void setName(DropboxClient dropboxclient) {
this.dropboxclient = dropboxclient;
}
}
In MyFirstActivity Activity:
private MyApplication app;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
app = (MyApplication)getApplication(); //Get Application
app.setName(dropboxclient);
Intent intent = new Intent();
intent.setClass(this, MySecondActivity.class);
startActivity(intent);
In MySecondActivity Activity:
private MyApplication app;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
app = (MyApplication)getApplication(); //Get Application
DropboxClient dropboxclient=app.getName();//Access global value

do the following,
start the activity with startActivityForResult()
startActivityForResult(0, MyActivity.class);
before your started activity finished, in the started activity, create an intent, and put whatever data you want to pass back as extras in the intent. now call setResult(..., intent);
Intent resultIntent = new Intent();
resultIntent.putExtra("myKey", myVal);
setResult(0, resultIntent);
in your starting activity, implement onActivityResult(), and handle the result of the started activity. you will be passed an Intent, which is the intent where you added extras in the started activity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    //TODO handle here. 
}

Extend Application class and declare and initialize your cross activity objects in that class and write getters for those objects.
now using following code in an activty, you can access those Objects.
getApplication().getMyObject().doSomeAction();
remember, you will have to modifiy your androidManifest.xml to tell android about your extended application class.

Solution:
Using StartActivityforResult there data moveback to Second Activity to First Activity
One Example there data move to second Activity to first Activity-
