How to prevent AutoComplete of two different search fields

First off, please excuse my attempt at trying to solve the problem I'm about to describe.
Problem: I have two search fields, 1) "Enter Origin Address" and 2) "Enter Destination Address". Within these fields, a user can enter an address and the Google Places API launches to present various predicted addresses from which the user can make a selection. My issues is that after the user selects an "Origin" address, both search fields are populated (instead of just the "Origin" field).
Here is my code. Again, please excuse my ignorance, particularly with the fillinAddress2 method...

Unable to properly parse json file

I'm working on a random quote app, and I need to parse ajson file through an http connection. I'm succesfully stablishing the connection; and fetching json data, but when I try parsing it, it seems I'm getting the keys, value, or object not mapped correctly. Or maybe I'm not using the correct code. Any help appreciated. Thanks

You are not getting a valid json from the url. First rectify your string then parse the json . try below code. This is only a temporary solution.
try {
String requiredString = quote.substring(quote.indexOf("(") + 1, quote.indexOf(")"));
JSONArray ja = new JSONArray(requiredString );
JSONObject jo = (JSONObject) ja.get(0);
randQuote = jo.get("content").toString().replaceAll("\\<[^>]*>","");
author = jo.get("title").toString();
Log.v("QUOTE", randQuote+" "+author);
}

The problem is the _jsonp=mycallback parameter in the url. Using this parameter is causing malformed JSON to be returned to you.
As you can see in the documentation, the JSONP parameter is used in JavaScript in order to execute a callback.
Since you're using Java in an Android app, there is no need to specify a callback.
All you need to do is modify the url so that it doesn't define a callback:
String url = "http://quotesondesign.com/wp-json/posts?filter[orderby]=rand&filter[posts_per_page]=1";
Then, the response will be valid formatted JSON, for example:
[
{
"ID":1572,
"title":"Si Scott",
"content":"<p>I really like looking at design and thinking: that attention to detail must have taken absolutely ages.<\/p>\n",
"link":"https:\/\/quotesondesign.com\/si-scott\/",
"custom_meta":{
"Source":"<a href=\"http:\/\/www.formatmag.com\/art\/si-scott\/\">article<\/a>"
}
}
]
Then, your existing code should work. I just tested it, and it logged the correct response:

unable to search database from button.setOnClick .getText as String becomes null

I am making android app that takes user input from EditText on press of button from button.setOnClick() and use the string.getText() to search the database. But the string becomes null and no way i can send it
DbBackend.class where the search function is.
I checked and database works fine on static query which you can set to = "xyz" but no way i am able to use the user input to query the database.
Here is my code: MainActivity.java
package com.vadhod.dictcopy;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.graphics.Typeface;
import android.support.v7.app.AppCompatActivity;

import static android.app.PendingIntent.getActivity;
public class MainActivity extends AppCompatActivity {

#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final DbBackend dbBackend = new DbBackend(MainActivity.this);
searchBar = (EditText) findViewById(R.id.searchBar);
searchButton = (Button) findViewById(R.id.searchButton);
textView = (TextView)findViewById(R.id.textView);
searchButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
String input = searchBar.getText().toString();
ArrayList<String> terms = dbBackend.getList(input);
StringBuilder builder = new StringBuilder();
for (String details : terms) {
builder.append(details + "\n");
}
textView.setText(builder.toString());
}catch (Exception e){
e.printStackTrace();
}
}
});
}
}
DbBackend.java
package com.vadhod.dictcopy;
import ...
public class DbBackend extends DatabaseObject {
public DbBackend(Context context){
super(context);
}
public ArrayList<String> getList(String search){
ArrayList<String> kWords = new ArrayList<String>();
String searchQuery = "SELECT kName FROM dictionary WHERE eName LIKE '%" + search + "%'";
try {
Cursor kCursor = this.getDbConnection().rawQuery(searchQuery, null);
if (kCursor != null){
kCursor.moveToFirst();
for (int i = 0; i < kCursor.getCount(); i++ ){
String sword = kCursor.getString(kCursor.getColumnIndexOrThrow("kName"));
kWords.add(sword);
kCursor.moveToNext();
}
kCursor.close();
return kWords;
}
return kWords;
}catch (Exception e){
e.printStackTrace();
}
return kWords;
}
}
Any help please on how to use the string when user press the search button and search that through the database and return the query?
Updated the moved code

Assuming that inside the searchButton.setOnClickListener(new View.OnClickListener() {...}); the search is working, and outside - not. The problem is your
//Option 1 not working
ArrayList<String> terms2 = dbBackend2.getList(input);
is called during the Activity setup before any view is shown to the user. So, the input is not filled at that time. You have to move this code into an onclick listener, like you did in the code above these lines.
Or provide some other source for the input.
Upd:
For the NullPointer: in your layout file activity_main you need to have a TextView with id textView. Because you do the following:
// find the textview in the layout
textView = (TextView)findViewById(R.id.textView);
// do the search, get results
...
// set textview's text, at this moment textView must not be null
textView.setText(kbuilder.toString());

Fatal Exception main at onclick

Im getting E/AndroidRuntime: FATAL EXCEPTION: main at com.test.megatest.Main4Activity$1.onClick(Main4Activity.java:37).
Ive read tons of posts on this forum but I cant figure out what Im missing,
This is the Main4Activity.java:
package com.test.megatest;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
public class Main4Activity extends AppCompatActivity {
EditText inputText;
TextView response;
Button saveButton, readButton;
private String filename = "SampleFile.txt";
private String filepath ="MyFileStorage";
File myExternalFile;
String myData ="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main4);
inputText = (EditText) findViewById(R.id.myInputText);
response = (TextView) findViewById(R.id.response);
saveButton =(Button) findViewById(R.id.saveExternalStorage);
saveButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
try {
FileOutputStream fos = new FileOutputStream(myExternalFile); //LINE 37
fos.write(inputText.getText().toString().getBytes());
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
inputText.setText("");
response.setText("SampleFile.txt saved to somewhere..");
}
});
}
}
Can someone here just point me in the right direction? :)

The file you try to open an output stream for is NULL.
You declared it as a member but never initialized it.

Initialize file as
File myExternalFile=new File("SampleFile.txt");

Your Main4Activity has a "File" variable:
File myExternalFile;
But without assigning any object/value to that variable You are trying to use it in:
FileOutputStream fos = new FileOutputStream(myExternalFile);
Obviously you will get an Exception for that :P
You should initialise "myExternalFile" using any of the 4 public constructors specified at java.io.File (depending on your use case).
For example:
// If you need a "Persistent" file in private directory of your application
//
myExternalFile = new File(this.getFilesDir() ,"name_of_your_file.txt");
//
// or
// If you need a "Cache" file
myExternalFile = new File(this.getCacheDir() ,"name_of_your_file.txt");
Locations of above files on your Android filesystem is:
# Persistent: /data/data/com.test.megatest/files or
(Any File Manager App) /Android/data/com.test.megatest/files
# Cache: /data/data/com.test.megatest/cache or
(Any File Manager App) /Android/data/com.test.megatest/files
Reference:
1) java.io.FileOutputStream -> FileOutputStream (File file) public constructor
"Creates a file output stream to write to the file represented by the specified File object"

Streaming live camera feed in app using android studio

I'm creating an app that I want to stream my foscam live feed in. I'm pretty new to coding and some of this code is over my head. I found some help getting this far but now am hitting a snag.

Make sure that Android's MediaPlayer can actually open and decode your stream. Right now, if the MediaPlayer cannot handle your stream, you are catching any exception and silently ignoring it:
try {
// Specify the IP camera’s URL and auth headers.
_mediaPlayer.setDataSource(context, source, headers);
// Begin the process of setting up a video stream.
_mediaPlayer.setOnPreparedListener(this);
_mediaPlayer.prepareAsync();
} catch (Exception e) {}
At the very least you should log the error:
} catch (Exception e) {
Log.e("MyApp", "Could not open data source", e);
}
Although the MediaPlayer service will most likely pepper the log with its own errors. So what you should do is review the logcat for any messages from the "VideoDecoder" or similar.
To see the logcat in Android Studio, open the "Android Monitor" tab which is on the bottom by default. If you want to see the unfiltered logcat make sure that in the top-right corner of the Android Monitor view it says "No Filters" instead of "Show only selected application".
