AsyncTask() failing on HttpsURLConnection.getOutputStream()

[Brian Tkatch]

I am still fumbling through Android, today, in trying to create an AsyncTask to connect to a website, post some data, and get a response. My understanding is that i must use an AsyncTask here, as the main thread is not allowed to do this sort of work. And, iiuc, AsyncTask threads are not available for debugging with the Studio debugger.

        protected InputStream doInBackground(JSONObject... request)
        {
            final String TAG = "moo";

            HttpsURLConnection connection = null;

            try
            {
                // Connect to the URL
                URL url = new URL("https://speech.googleapis.com/v1/speech:recognize");
                connection = (HttpsURLConnection) url.openConnection();

                // Since we're sending and receiving data, Do (DataOutput) must be true.
                connection.setRequestMethod("POST");
                connection.setDoOutput(true);
                connection.setDoInput(true);

                // Add headers (from https://cloud.google.com/speech/docs/getting-started (step 4))
                connection.setRequestProperty("Content-Type", "application/json");
                connection.setRequestProperty("Authorization", "Bearer access_token");

                // When the length is known, no buffering required.
                // See https://developer.android.com/reference/java/net/HttpURLConnection.html
                connection.setFixedLengthStreamingMode(request[0].toString().length());

                Log.d(TAG, "doInBackground: 1");
                DataOutputStream stream = new DataOutputStream(connection.getOutputStream());
                Log.d(TAG, "doInBackground: 2");
                stream.writeChars(request[0].toString());
                stream.flush();
                stream.close();

                // Get the response code and leave if it is an error.
                response_code = connection.getResponseCode();
                if (response_code / 100 != 2) return null;

                // Grab the result.
                return connection.getInputStream();
            }
            catch (Exception e)
            {
                Log.d(TAG, "doInBackground: exception");
                e.printStackTrace(); return null;
            }
            finally{if(connection != null) connection.disconnect();}
        }

The log shows "1" then "exception," as it fails on connection.getOutputStream(). I have verified it is that specific method by splitting up the statement, and setting connection.getOutputStream() to an interim variable in it's own line of code.

How to determine what the error is?

Post the full stack trace.

Why didn't i think of that? I feel kind of silly now. I had forgotten to remove my filter, thus i never saw when it said: java.lang.SecurityException: Permission denied (missing INTERNET permission?)

I did have the following line in AndroidManifest.xml: <uses-permission android:name="INTERNET"/>
But, a simple search found that should have been: <uses-permission android:name="android.permission.INTERNET"/>

It also says i need i also needed: <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>, but we'll wait and see on that one. Right now i have a different bug to work out.

Thank you!
