Actually I want to do speech to text continuously in the background so actually I am using the solution which is given in the below link but i m not getting how can i implement it. link
I have done this so far but still my service is not running and i am not getting any output So I think that i have done something wrong in its implementation.Please help me and correct my code in order to run service and get my output
This is my mainactivity.java
public class MainActivity extends AppCompatActivity {
private int mBindFlag ;
private Messenger mServiceMessenger ;
private Button btStartService;
private TextView tvText;
@Override
protected void onStart() {
super.onStart();
Log.d("check", "onStart: ");
bindService(new Intent(getApplicationContext(), MyService.class), mServiceConnection, mBindFlag);
}
@Override
protected void onStop() {
super.onStop();
if (mServiceMessenger != null) {
unbindService(mServiceConnection);
mServiceMessenger = null;
}
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent service = new Intent(this, MyService.class);
this.startService(service);
mBindFlag = Context.BIND_ABOVE_CLIENT;
Log.d("check", "onCreate: "+mBindFlag);
btStartService = (Button) findViewById(R.id.btStartService);
tvText = (TextView) findViewById(R.id.tvText);
int PERMISSION_ALL = 1;
String[] PERMISSIONS = {
Manifest.permission.RECORD_AUDIO
};
if (!hasPermissions(this, PERMISSIONS)) {
ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}
}
public static boolean hasPermissions(Context context, String... permissions) {
if (context != null && permissions != null) {
for (String permission : permissions) {
if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
return false;
}
}
}
return true;
}
private final ServiceConnection mServiceConnection = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName name, IBinder service)
{
if (DEBUG) {
Log.d("check", "onServiceConnected");} //$NON-NLS-1$
mServiceMessenger = new Messenger(service);
Message msg = new Message();
msg.what = MyService.MSG_RECOGNIZER_START_LISTENING;
try
{
mServiceMessenger.send(msg);
}
catch (RemoteException e)
{
e.printStackTrace();
}
}
