NullPointerExcepter Error when using List Adapter and Custom List View in Android Studio

Been trying to write an app in android studio. Part of the app has to parse a document in JSON and display two TextViews of data for each instance. One being Signal and the other being Noise. I am trying to make a custom list view in case I want to add more detail to each instance. I also would like to make it all contained in a ScrollView. I initially had no problems parsing the document but now that I am trying to implement the ListAdapter I am running into issues.
My code is giving me the error...
E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.yesinc.tsi880, PID: 4919
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ListView.setAdapter(android.widget.ListAdapter)' on a null object reference
at com.yesinc.tsi880.TelemetryActivity$JSONTask.onPostExecute(TelemetryActivity.java:136)
at com.yesinc.tsi880.TelemetryActivity$JSONTask.onPostExecute(TelemetryActivity.java:50)
Not sure if the problem is with the document that I am trying to parse or the java code itself. Any help would be much appreciated. Code is below.

ListView lvSondes = findViewById(R.id.lvSondes);
You are re-declaring the lvSondes inside your onCreate method. The class member list view is never used and is never initialized. Instead a local lvSondes is initialized. This variable will not be in scope and won't be visible to the AsyncTask. The async task will use the member variable and that will be null.
Solution: remove the ListView from the stated line and just initialize the member variable

Android - after notifyDataSetChanged ListView remains blank

It's hours I search for something, but it doesn't seem to help.. Android Studio doesn't launch any error, but the screen remains blank. Why?

#Override

setContentView(R.layout.activity_main);
RssItem[] rssItems = new RssItem[]{};
rssItemsArrayAdapter = new ArrayAdapter<RssItem>(this, android.R.layout.simple_list_item_1, rssItems);
new WebCall().execute(rssItems);
codeLearnLessons = (ListView)findViewById(R.id.listView1);
codeLearnLessons.setAdapter(rssItemsArrayAdapter);
}
#Override

getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
private class WebCall extends AsyncTask<RssItem, Void, Void> {

URL url = null;
try {

} catch (MalformedURLException e) {
e.printStackTrace();
}
try {
ArrayList<RssItem> listItems = RssReader.read(url).getRssItems();
items = listItems.toArray(new RssItem[listItems.size()]);
final int l = items.length;
runOnUiThread(new Runnable() {
#Override
public void run() {
codeLearnLessons.invalidateViews();
rssItemsArrayAdapter.notifyDataSetChanged();
Log.i("rec", "rec" + l);
}
});
} catch (SAXException e) {

} catch (IOException e) {

return null;
}
#Override

/*ProgressDialog mDialog = new ProgressDialog(MainActivity.this);
mDialog.setMessage("Please wait...");
mDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
mDialog.setIndeterminate(true);
mDialog.setCancelable(false);
mDialog.show();*/
}
}
}

The issue is that your using a ArrayList which only has scope inside of the AsyncTask.doInBackground() method. Since it is not given to the adapter, the notifyDataSetChanged() does nothing. You'll need to replace the existing array like this:
rssItemsArrayAdapter.clear();
rssItemsArrayAdapter.addAll(listItems);
rssItemsArrayAdapter.notifyDataSetChanged();
Having said that, you also really need to change your use of AsyncTask. There's no need to call runOnUiThread() from within your doInBackground() as the AsyncTask will automatically run its onPostExecute() on the UI thread. Have your doInBackground() method return your new ArrayList<RssItem> and create an onPostExecute() override method which adjusts the adapter as shown above.

You are passing your items to the AsyncTask but in the AsyncTask you declare them new with the content of your result. You never pass the items to your ArrayAdapter back. Make them a property of your class instance.
Edit - Example:
rssItemsArrayAdapter.clear();
rssItemsArrayAdapter.addAll(items);
and afterwards
rssItemsArrayAdapter.notifyDataSetChanged();

How can I make this app more efficient?

I have the following code which is working without any errors, but I get this
Skipped 116 frames. The application may be doing too much work on its main thread.
That happens when I press the Single button and the init() method is executed.
How can I execute the method in another thread so it won't break like that ?

You are doing the Bluetooth related calls on the UI thread and you blocking the UI thread with these calls.

Try this:

The example video is for desktop java, where you can normally write files without specifying a path. However on Android you should always specify one - you can use internal storage or external storage. Here's the Android guide on how to write files to internal storage: http://developer.android.com/guide/topics/data/data-storage.html#filesInternal

Send Base64 image from Android with JSON to php webservice, decode, save to SQL
How to convert image into byte array and byte array to base64 String in android?

you should send it as a Multipart Entity. this way you can send image and other string parameters together.
For this you will need the following files
apache-mime4j-0.6.jar
