I have a problem with my android app with speech recognition.My problem is that I want to show the same speech recognition input screen as is shown from the jellybean keyboard. If I invoke the Speech recognition intent from code, it does not keep listening and stops prematurely.
There must be a simple way to do this, but I can't find it.
here is my code
package com.bsdcservices.recognitiontest;
import java.util.ArrayList;
import java.util.Locale;
import android.os.Bundle;
import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Context;

import android.speech.RecognizerIntent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
private final String TAG = "RecognitionTest";
private final int SPEECHRECOGNITION_RESULTCODE = 0;
private EditText editText;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText = (EditText) findViewById(R.id.textbox);
Button recognize = (Button) findViewById(R.id.recognize);
recognize.setOnClickListener(buttonClickListener);
}
public OnClickListener buttonClickListener = new OnClickListener(){
#Override
public void onClick(View v) {
startSpeechRecognitionActivity();
}
};
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
void startSpeechRecognitionActivity(){
// MyApplication.speechRecognitionActive = true;
// main.startSpeechRecognizer(TABSPEAK);
try{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass().getPackage().getName());
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault().toString());
startActivityForResult(intent, SPEECHRECOGNITION_RESULTCODE);
} catch (ActivityNotFoundException error) {
Toast.makeText(getBaseContext(), "Speech recognition is not supported by your device" , Toast.LENGTH_LONG).show();
} catch( RuntimeException error ) {
Toast.makeText(getBaseContext(), error.getMessage() , Toast.LENGTH_LONG).show();
error.printStackTrace();
}
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
try
{
if (requestCode == SPEECHRECOGNITION_RESULTCODE) {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
editText.append(text.get(0));
}
}
} catch( RuntimeException error ) {
Toast.makeText(getBaseContext(), error.getMessage() , Toast.LENGTH_LONG).show();
error.printStackTrace();
}
}

I'm trying to implement the facebook login. I have followed everything from here.
https://developers.facebook.com/docs/facebook-login/android/v2.3
And I am trying to make a Graph API call to retrieve user data; however, when I do so I get this.
Warning: Request without access token missing application ID or client token.
I believe I have implemented this login correctly and followed all the steps.
I have done some research on this and since sessions are deprecated in this current Facebook API version it has been of no help.
Is there anything blatantly wrong with my implementation that would cause Facebook Login not to be validated for the user?

You need to start your second activity with the flag that you are waiting for a result, so instead of startActivity you need to make use of startActivityForResult.
If you need a little bit more information take a look at this tutorial it should cover all you need to get things working.
I'm new in Java and my English isn't the best too.
I want to write an app which meassures the Amplitude of a record. The app works except for the fact, that the amplitude is always 0. I have now read several websites, but didn't found an answer. I would be realy glad if somebody helps me.

Thank you for your help!
I have the same issue, and oddly enough if you change the time interval when your trying to get the max amplitude, to greater then one second, it works normally, but i don't know what's causing it ...

In the mainActivity, everytime button abButton is pressed, it increases the count variable by 1. It also creates a new intent and sends that variable via extra to that intent.
In the second activity, the "values" variable getting the data from the intent is giving me a null pointer exception. Why?
Intent intent = new Intent(this, SecondpageActivity.class);
startActivity(intent);
intent.putExtra("count", count);
Change to
Intent intent = new Intent(this, SecondpageActivity.class);
intent.putExtra("count", count);
startActivity(intent);
You are setting the extra after you've already started the 2nd activity
just alter these two code lines,
Intent intent = new Intent(this, SecondpageActivity.class);
intent.putExtra("count", count);
startActivity(intent);
Your SecondActivity Intent start before setting the extra count to it.
