    <p>EDITED: I have changed my service code to implement as started service instead of IntentService as updated StreamService.java below Now, I am getting error regarding permission denial error as described in logcat messages after StreamService.java</p> <p>EDITED:</p> <pre><code>As mentioned in Android Developer site that SpeechRecognizer API can only be used as Application Context. Is there any woraround with which I can get it working </code></pre> <p>I have implemented MainActivity class that has all the UI Components. Class is as below</p> <p>CODE - MainActivity.java</p> <pre><code>package com.example.speechsensorservice; import android.app.Activity; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.content.IntentFilter; import android.os.Bundle; import android.util.Log; import android.view.Menu; import android.view.View; import android.widget.ImageButton; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends Activity { private static final String TAG = "SpeechSensor"; private boolean headsetConnected = false; public TextView txtText; private BroadcastReceiver mReceiver; private ImageButton btnSpeak; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txtText = (TextView) findViewById(R.id.txtText); btnSpeak = (ImageButton) findViewById(R.id.btnSpeak); btnSpeak.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(getApplicationContext(),StreamService.class); startService(intent); } }); } protected void onResume() { super.onResume(); IntentFilter sIF = new IntentFilter(); sIF.addAction(Intent.ACTION_HEADSET_PLUG); sIF.addAction("com.example.speechsensorservice.TEXT"); mReceiver = new BroadcastReceiver() { @Override public void onReceive(Context arg0, Intent arg1) { // TODO Auto-generated method stub String act = arg1.getAction(); Log.d(TAG, "Received Action = " + act); if ( Intent.ACTION_HEADSET_PLUG.equals(act) ) { if ( arg1.hasExtra("state")) { if ( !headsetConnected &amp;&amp; arg1.getIntExtra("state", 0) == 1 ) { headsetConnected = true; txtText.setText("Headset Plugged in"); startNoiseProcessService(); } } } else if ( act.equals("com.example.speechsensorservice.TEXT") ){ if ( arg1.hasExtra("Identity")) { String s = arg1.getStringExtra("Identity"); if ( s.equals("NA") ) { Toast t = Toast.makeText(getApplicationContext(), "Your Device doesnot support Speech to Text", Toast.LENGTH_SHORT); t.show(); } else txtText.setText(s); } } } }; this.registerReceiver(mReceiver, sIF); } public void onPause() { super.onPause(); this.unregisterReceiver(this.mReceiver); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.main, menu); return true; } public void startNoiseProcessService() { Intent intent = new Intent(this,StreamService.class); startService(intent); } } </code></pre> <p>Another class that I have implemented to start Speech Recognition Service as a background task by inheriting IntentService class.

    1. CO[IntentService#onHandleIntent()](http://developer.android.com/reference/android/app/IntentService.html#onHandleIntent%28android.content.Intent%29) documentation says "worker thread". Use a regular service and override `onStartCommand`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
