Intent move from one to other activity and do oncreate in other activity

I have 2 activity, Tambah and Tampil activity.
I use Tambah activity to add new data (form and button submit), and after submit, it will move to Tampil activity. in Tampil activity will show the list view of data (i'm using Volley). all script works, no error. but in Tampil activity only showing old data (like before add), not showing the newest data.
here my Tambah acitivity

how can when Intent from Tambah activity to Tampil activity, the Tampil activity reload all data include newest data)?

It seems that you are not waiting until data is uploaded and redirecting to next screen.
Try this answer
Implementing ProgressDialog in Multipart Upload Request
onCompleted redirect to next screen

This is the error that I'm getting everytime I press the upload button after selecting an image from the device

calling another class functions from one class on button click in android

I am making an app with various activities and each activity uses the camera function which is defined in another class. I want that in each activity when the camera button is clicked the camera class is called.
This is my main class:-
package com.example.ishan.complainbox;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.lang.String;
public class Crime extends MainActivity implements View.OnClickListener
{
camera cam=new camera();
EditText str,city,pn,det;
Button save,pic;
crimeDBHandler dbHandler;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_crime);
// Get References of Views
str = (EditText) findViewById(R.id.str);
city = (EditText) findViewById(R.id.city);
pn = (EditText) findViewById(R.id.pin);
det = (EditText) findViewById(R.id.detail);
save = (Button) findViewById(R.id.save);
pic=(Button) findViewById(R.id.uploadpic);
dbHandler = new crimeDBHandler(this, null, null, 1);
}
public void onClick(View view) {
String street = str.getText().toString();
String cty = city.getText().toString();
String pin = pn.getText().toString();
String detail = det.getText().toString();
// check if any of the fields are vaccant
if(str.equals("")||city.equals("")||pn.equals("")||det.equals(""))
{
Toast.makeText(getApplicationContext(), "Field Vacant",
Toast.LENGTH_LONG).show();
return;
}
// check if both passwords match
else
{
// Save the Data in Database
dbHandler.insertEntry(street,cty,pin,detail);
Toast.makeText(getApplicationContext(), "Complaint Successfully
Filed ", Toast.LENGTH_LONG).show();
}
}
};
.....and this is the camera class..:-

This can be achieved through regular inter-activity communication mechanisms like passing intents or using broadcast receivers. I would suggest using intents - Refer this basic example from Android doc: https://developer.android.com/training/basics/firstapp/starting-activity.html
EDIT
Response to OP's question in comment-
You have to save the image file to FS in your Camera Class and pass the file name as an Extra with the intent to your Crime class. Since you are dealing with storage your Apps's manifest now would need additional permissions. I would recommend you go through this thread: Camera is not saving after taking picture

Starting camera activity, app crashes

I have problem, that I have been searching for whole week. I'm creating app that sends photo and some data to server. The problem is that when I start activity, camera has to start but, for some devices app crashes. I cant describe the error because devices are in other cities. I have LG G3 and HUAWEI P7 on both of them works fine. I think this might be something wrong with permissions but I'm not sure.

It might look dumb why I have if in onCreate() method, it's because in my LG G3 camera is restarting on taking photo. And thats why my onActivityResult() method looks strange.

P.S. My code might look unclean, sorry for that, I have been doing everything and testing everything to solve that problem.
BTW I'm requesting permission for storage in my LoginActivity and there I'm creating folder for photos.

So I figured out where the problem was.
The error was exposed beyond app through ClipData.Item.getUri() . Basicly the problem was in this line i.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);. After searching for this error I found solution in this post

Back to the previous activity on back pressed

I have a function which display FileDialog and Intent to use Bluetooth.
But when I press back button, it comes to previous activity, it is visible but not clickable (like screenshot) and I have to press the back button once again.
I tried function onBackPressed() { finish(); }, but nothing worked properly.
MainActivity:
...
if(item == shareMenu) {
startActivity(new Intent(getBaseContext(), ShareViaBluetoothActivity.class));
}

What you described was not so complete. But I this there are some reasons may result to this, then you can check it.
1. use super.onBackPressed() or give onBackPressed() return can make different
2. please check activity launch mode work.
but you'd better give a more detailed code,then I can help you
