I am trying to use Voice Recognition on Android. Following is my code.
This is the code of the Button that is responsible to start speech recognition.
speak.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View v)
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "City Name Please?");
startActivityForResult(intent, REQUEST_CODE);
}});
Here is a onActivityResult method.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
ArrayList<String> matches_Text = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
Log.v("Results", matches_Text.get(0).toString());
//Update EditText cityname here
String normalized_cityname = matches_Text.get(0).toString().trim();
normalized_cityname = normalized_cityname.replace(" ","%20");
try {
getResponseString("http://api.openweathermap.org/data/2.5/weather?q="+normalized_cityname+"&units=metric", true);
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}
}
The code worked ok but there are two problems I am encountering now and I am afraid that they may be related.
If I try to update text in an EditText instance cityname using cityname.setText(matches_Text.get(0).toString()), it crashes the app.
If I hit the speak button now, the google voice dialog comes up but shows can't reacg google at the moment.
Please suggest what can I do?
Adding the getResponseString method also.
public void getResponseString(String Url, boolean IsCalledOnVoiceInput) throws IOException, JSONException {
String temperature="";
String city;
String country;
String weather_main, weather_description;
MyAsyncTask xxx = new MyAsyncTask();
try {
String responseString = xxx.execute(Url).get();
TextView txtTemp = (TextView)findViewById(R.id.txt_temp);
TextView txtCity = (TextView)findViewById(R.id.txt_CityName);
TextView txtWeatherMain = (TextView)findViewById(R.id.textView2);
TextView txtWeatherDescription = (TextView)findViewById(R.id.textView3);
JSONObject reader = new JSONObject(responseString);
JSONObject main = reader.getJSONObject("main");
temperature = main.getString("temp");
Log.v("temperarure",temperature);
city = reader.getString("name");
Log.v("city",city);
JSONObject sys = reader.getJSONObject("sys");
country = sys.getString("country");
Log.v("country",country);
JSONArray weather = reader.getJSONArray("weather");
JSONObject weather_obj = weather.getJSONObject(0);
weather_main = weather_obj.getString("main");
weather_description = weather_obj.getString("description");
txtTemp.setText(temperature+" °C");
txtCity.setText(city+" ("+country+")");
txtWeatherMain.setText(weather_main);
txtWeatherDescription.setText(weather_description);
if(IsCalledOnVoiceInput)
Speak_Weather_Data(city,temperature,weather_main,weather_description);
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
} catch (JSONException e){
e.printStackTrace();
}
}
Here is the log output

is this what you mean?
i think matches_Text is sometimes NULL?! how about adding an
if(matches_Text == null){
Log.v("Results","matches_Text is NULL!");
return;
}
add above code just after ArrayList<String> matches_Text = da...

I am developing an app in which my requirement to select an image from the SD card and send in to IBM Waston Visual Recognition service to identify the content in the image. I am doing like this..
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, RESULT_LOAD_IMAGE);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == RESULT_LOAD_IMAGE && resultCode == MainActivity.this.RESULT_OK && null != data){
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = MainActivity.this.getContentResolver().query(selectedImage,filePathColumn,null,null,null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
analizarImagen(picturePath);
}
}
private void analizarImagen(String path){
File image = new File(path);
System.out.println(path);
VisualRecognition service = new VisualRecognition(VisualRecognition.VERSION_DATE_2016_05_20);
service.setApiKey("api-key");
ClassifyImagesOptions options = new ClassifyImagesOptions.Builder()
.images(image)
.build();
VisualClassification result = service.classify(options).execute();
System.out.println(result.toString());
}
But when I select an image, the application crashes

You are hitting server from main(UI) thread which is not allowed in android. Call your analizarImagen() method in separate thread or async task.
Check this document:
https://developer.android.com/reference/android/os/NetworkOnMainThreadException.html
If wifi or mobile data is not enabled, it should ask the user, if he clicks yes in the AlertDialog, it will go to the settings.
This is inside main, on create, when the update button clicked:
btnUpdate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.v(TAG,"ButtonUpdate clicked");
connectIfNecessary();
currentDate = Calendar.getInstance();
formatter= new SimpleDateFormat("yyyy-MM-dd");
new UpdateDB(MainActivity.this);
txtLastUpdateShow.setText(formatter.format(currentDate.getTime()));
});
This is connectifnecessary:
public void connectIfNecessary(){
Log.v(TAG, "main connectIfNecessary");
if(!isConnected()){
final Context ctx = this;
AlertDialog.Builder builder = new AlertDialog.Builder(ctx);
builder.setCancelable(true);
builder.setMessage("need internet");
builder.setTitle("do you want to enable it now?");
builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
ctx.startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
}
});
builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
return;
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
public void onCancel(DialogInterface dialog) {
return;
}
});
builder.show();
}
}
this is isConnected:
public boolean isConnected(){
Log.v(TAG, "mainisconnected");
ConnectivityManager conectivtyManager = (ConnectivityManager)
getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
if (conectivtyManager.getActiveNetworkInfo() != null
&& conectivtyManager.getActiveNetworkInfo().isAvailable()
&& conectivtyManager.getActiveNetworkInfo().isConnected()) {
Log.v(TAG, "mainisconnected true");
return true;
} else {
Log.v(TAG, "mainisconnected false");
return false;
}
}
in updatedb constructor, it will call asynctask to connect websites.
When i run this, and click update button, it crashes because it goes into updatedb withpout asking me in builder. The errors:

MainActivity.java:106) is builder.show()
MainActivity.java:276) connectIfNecessary();
I am getting errors for hours, at first about appcompat, then manifest then layout now this.
I use real tablet device.
When device is not connected , following would be execution flow
Get inside connectIfNecessary()
Create Alert to ask user to enable internet. Please note that only Alter object is created at this moment, it will be displayed on screen only after stack of main thread unwinds.
Return from connectIfNecessary() create instance of updateDB(). Inside this application is crashing
Few simple changes would fix your code.
add isConnected() if check before creating instance of updateDB(). This will cover the CONNECTED case
if the device is NOT CONNECTED, user will shown the alter and take to settings screen. If user enables WIFI from settings and comes back, onResume() of your activity will be called. Check connectivity and add updateDB() here.

onResume() always gets called after onCreate().
When onResume() begins, mDBApi is null, because this field is only ever assigned in the onClick() method.
You either need to assign mDBApi in onCreate() directly, or you need to check that it is not null before you try to use it.

Android Camera : data intent returns null
(11 answers)
Closed 8 years ago.
Here's what the app does - User clicks button (to take a picture) on Activity A, the captured image gets set as on an ImageView in Activity A, and then the user clicks a "save" button, which takes him/her to Activity B, where the image they took gets displayed (on an ImageView in Activity B)
In order to do this I am trying to find a way to save the image. I tried many different things, but I keep getting a NullPointerException. Here is my code:
I highlighted the area where I think the error is:
public void onClick(View view) {
switch (view.getId()) {
case R.id.take_picture_button:
takePic = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
if (takePic.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
photoFile = createImageFile(); //so photoFile = the file we created up top
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
**takePic.putExtra(MediaStore.EXTRA_OUTPUT**, //extra_output is just the name of the Intent-extra used to indicate a content resolver Uri to be used to store the requested image or video.
**Uri.fromFile(photoFile));**
startActivityForResult(takePic, cameraData);
}
And here is the code for the onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == cameraData && resultCode == RESULT_OK) {
mReturningWithResult = true;
extras = data.getExtras();
And here is where I set my image view to my captured image (on Activity A)
#Override
protected void onPostResume() {
super.onPostResume();
if (mReturningWithResult) {
foodImage = (Bitmap) extras.get("data");
foodImageView.setImageBitmap(foodImage);
}
mReturningWithResult = false;//resetting it for next time
}
Here is the logcat (sorry I'm new to this)

Do you guys know a way I can fix this? Thank you!
You are passing MediaStore.EXTRA_OUTPUT, in which case, the intent field in onActivityResult can be null.
The solution is to just use the photo file you created, and passed as uri in the putExtra
So instead of trying to get the photo file location from the intent, just use Uri.fromFile(photoFile)
replace
extras = data.getExtras();
...
with
`Uri.fromFile(photoFile)`
or just use photoFile if that is what you want...just dont rely on intent data
I want my program to record audio for 10 seconds and then stop and store my record in file storage, everything works fine on my Nexus 4 and Galaxy S 5, but when i test it in Galaxy S3 it crushes and raise error

First i thought the error is in the file name, I'm declaring it like this:
public MainActivity() {
mFileName = Environment.getExternalStorageDirectory() + File.separator
+ Environment.DIRECTORY_DCIM + File.separator + "MyMemo.3gp";
//Environment.getExternalStorageDirectory().getAbsolutePath();
//mFileName += "/MyMemo.3gp";
}
Then i make a record like this:
private void startRecording() {
mRecorder = new MediaRecorder();
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mRecorder.setOutputFile(mFileName);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
try {
mRecorder.prepare();
mRecorder.start();
} catch (IOException e) {
Log.e(LOG_TAG, "prepare() failed");
}
}
Then i call the "StartRecording" method like this:
else if(command.equals("2")) {
startRecording();
Toast.makeText(getApplicationContext(), "Start recording...",
Toast.LENGTH_SHORT).show();
CountDownTimer start = new CountDownTimer(timer, 1000) {
#Override
public void onTick(long l) {
Toast.makeText(getApplicationContext(), "Recording!!!",
Toast.LENGTH_SHORT).show();
}
#Override
public void onFinish() {
stopRecording();
}
}.start();
you are not supposed to call mRecorder.start(); when mRecorder.prepare(); fails.
this is what caused the Illegal State Exception to be thrown.
Not all devices support all the encoding formats.
try changing these mRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
and mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
change the format and Encoder to a file format and encoding format your s3 device supports.
for a start, change your encoding setting to default settings as follows and try if it works.
mRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mRecorder.setOutputFormat(MediaRecorder.OutputFormat.DEFAULT);
mRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
