How to check if a music player is installed or not? - android

I am able to fetch the installed or running app list . Now I want to detect in the list is there any music player app present or not?
public void getRunningProcess() {
List<RunningAppProcessInfo> list2 = am.getRunningAppProcesses();
listdp = new ArrayList<DetailProcess>();
for (RunningAppProcessInfo ti : list2) {
if (ti.processName.equals("system") || ti.processName.equals("com.android.phone")) {
continue;
}
DetailProcess dp = new DetailProcess(this, ti);
dp.fetchApplicationInfo(packageinfo);
dp.fetchPackageInfo();
dp.fetchPsRow(pinfo);
if (dp.isGoodProcess()) {
listdp.add(dp);
}
}
Collections.sort(listdp);
adapter = new ProcessListAdapter(this, listdp);
}

this should do the trick.....
void someFunction(){
Intent intent = new Intent();
intent.setType("audio/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent,1);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
response="";
String filerealpath=null;
if (resultCode == RESULT_OK) {
System.out.println("mp3 player exists");
}
}

startActivityForResult doesnt return to onActivityResult in android

The first time I call startActivityForResult() with requestCode x it return to onActivityResult().But the second time I call startActivityForResult() within the same activity with diffrent requestCode it doesnt return to the onActivityResult() and just proceed
with the code.
I have tried to add this property to the manifest andter the activity
android:noHistory
Why it doesnt return to onActivityResult()?And how i can fix it?
Thanks a lot,
Leon
Edit: Here is my code
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
myTTS = new TextToSpeech(this, this);
}
else {
Intent installTTSIntent = new Intent();
installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installTTSIntent);
}
}
else if(RESULT_SPEECH == requestCode)
{
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
textFromSpeech = text.get(0);
}
}
}
private void getTextFromSpeech()
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
try {
startActivityForResult(intent, RESULT_SPEECH);
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Ops! Your device doesn't support Speech to Text",
Toast.LENGTH_SHORT);
t.show();
}
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_tts_);
/*
* New Intent purely for the purposes of checking the user data
*/
Intent checkTTSIntent = new Intent();
checkTTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkTTSIntent, MY_DATA_CHECK_CODE);
}

No result for RecognizerIntent.EXTRA_CONFIDENCE_SCORES

I have an application with the API Android VoiceRecognizer. It's work well but I can't get the confidence score of the result. For this I use RecognizerIntent.EXTRA_CONFIDENCE_SCORES but it's return no result. I have a device with the API 16 and I have specified on the manifest :
<uses-sdk
android:minSdkVersion="14"
android:targetSdkVersion="16" />
This is my code
public class MainActivity extends Activity {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001;
private ListView mlvTextMatches;
private Button mbtSpeak;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mlvTextMatches = (ListView) findViewById(R.id.lvTextMatches);
mbtSpeak = (Button) findViewById(R.id.btSpeak);
checkVoiceRecognition();
// Disable button if no recognition service is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0)
{
mbtSpeak.setEnabled(false);
mbtSpeak.setText("Recognizer not present");
}
}
public void checkVoiceRecognition() {
// Check if voice recognition is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
mbtSpeak.setEnabled(false);
mbtSpeak.setText("Voice recognizer not present");
Toast.makeText(this, "Voice recognizer not present",
Toast.LENGTH_SHORT).show();
}
}
public void speak(View view) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Straight talk please...");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "fr-FR");
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
if(resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
ArrayList<String> confidence = data.getStringArrayListExtra(RecognizerIntent.EXTRA_CONFIDENCE_SCORES); ;
if(confidence==null)
Log.d("VoiceRecognition","confidence null");
else
Log.d("VoiceRecognition","confidence "+confidence.size());
mlvTextMatches.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,matches));
}
super.onActivityResult(requestCode, resultCode, data);
}
}
Have you any ideas why I haven't result for the confidence score (I have 5 results for RecognizerIntent.EXTRA_RESULTS) ?
Thank you for your help.
In the link to EXTRA_CONFIDENCE_SCORES you'll see that it returns a float array, not a string array.
Therefore you'll have to use something like this:
float [] confidence = data.getFloatArrayExtra(RecognizerIntent.EXTRA_CONFIDENCE_SCORES);
Be aware though, there are some bugs identified with the confidence scores.

How to get the result of voice recognition on EditBox?

I know there is like a ton topic and question regarding Voice Recognition and my question might be a stupid one too. but please bear with me guys.
I need to get the result of the speech recognition into an (Editable Text Box) instead of (Array List), the editable text box to allow the user to edit the result , just like a memo.
I found some questions like mine but I could not understand ,I am still a beginner comparing to you guys .
This is the code :
public class AVRScreen extends Activity {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001;
private ListView mlvTextMatches;
private Button mbtSpeak;
private Button reButton;
private EditText result;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.vr_screen);
Toast.makeText(this, "Press Speak! to Start Speeking",
Toast.LENGTH_LONG).show();
result = (EditText) findViewById(R.id.out_text);
mlvTextMatches = (ListView) findViewById(R.id.lvTextMatches);
mbtSpeak = (Button) findViewById(R.id.btSpeak);
reButton = (Button)findViewById(R.id.Replay1);
reButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
startActivity(new Intent(v.getContext(),KeyBoard.class));
}
});
checkVoiceRecognition();
}
public void checkVoiceRecognition() {
// Check if voice recognition is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
mbtSpeak.setEnabled(false);
mbtSpeak.setText("Voice recognizer not present");
Toast.makeText(this, "Voice recognizer not present",
Toast.LENGTH_SHORT).show();
}
}
public void speak(View view) {
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);
//Start the Voice recognizer activity for the result.
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
//If Voice recognition is successful then it returns RESULT_OK
if(resultCode == RESULT_OK) {
ArrayList<String> textMatchList = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (textMatchList.get(0).contains("search")) {
} else {
// populate the Matches
mlvTextMatches .setAdapter(new ArrayAdapter<String>
(this,android.R.layout.simple_list_item_1,textMatchList));
}
}
//Result code for various error.
{
} if(resultCode == RecognizerIntent.RESULT_AUDIO_ERROR){
showToastMessage("Audio Error");
}else if(resultCode == RecognizerIntent.RESULT_CLIENT_ERROR){
showToastMessage("Client Error");
}else if(resultCode == RecognizerIntent.RESULT_NETWORK_ERROR){
showToastMessage("Network Error");
}else if(resultCode == RecognizerIntent.RESULT_NO_MATCH){
showToastMessage("No Match");
}else if(resultCode == RecognizerIntent.RESULT_SERVER_ERROR){
showToastMessage("Server Error");
}
super.onActivityResult(requestCode, resultCode, data);
}
/**
* Helper method to show the toast message
**/
void showToastMessage(String message){
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}
}
This is the code after editing :
public class AVRScreen extends Activity {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001;
private Button mbtSpeak;
private Button reButton;
private EditText myEditText;
#Override
public void onCreate(Bundle savedInstanceState) {

setContentView(R.layout.vr_screen);
Toast.makeText(this, "Press Speak! to Start Speeking",
Toast.LENGTH_LONG).show();
myEditText = (EditText) findViewById(R.id.out_text);
mbtSpeak = (Button) findViewById(R.id.btSpeak);
reButton = (Button)findViewById(R.id.Replay1);
reButton.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
startActivity(new Intent(v.getContext(),KeyBoard.class));
}
});
checkVoiceRecognition();
}
public void checkVoiceRecognition() {
// Check if voice recognition is present
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(
RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if (activities.size() == 0) {
mbtSpeak.setEnabled(false);
mbtSpeak.setText("Voice recognizer not present");
Toast.makeText(this, "Voice recognizer not present",
Toast.LENGTH_SHORT).show();
}
}
public void speak(View view) {
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);
//Start the Voice recognizer activity for the result.
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE)
//If Voice recognition is successful then it returns RESULT_OK
if(resultCode == RESULT_OK) {
ArrayList<String> textMatchList = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (textMatchList.get(0).contains("search")) {
} else {
// populate the Matches
myEditText.setText(textMatchList.toString());
// if the above does not look good
// for (String match : textMatchList) {
// myEditText.append(match + "\n"); // or whatever separator you want
// }
}
}
the second try is :
} else {
// populate the Matches
//myEditText.setText(textMatchList.toString());
// if the above does not look good
for (String match : textMatchList) {
myEditText.append(match + "\n"); // or whatever separator you want
}
}
}
if(resultCode == RESULT_OK) {
ArrayList<String> textMatchList = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if (textMatchList.get(0).contains("search")) {
} else {
// populate the Matches
result.setText(textMatchList.toString());
// if the above does not look good
// for (String match : textMatchList) {
// result.append(match + "\n"); // or whatever separator you want
// }
}

How to implement recognizer on Android

My software architecture as below:
TabActivity is a TabHost Activity.
It contain 2 ActivityGroup: AGroup and BGroup.
AGroup contain 2 Activities: A1Activity and A2Activity.
I want to implement recognizer in A1Activity.
My code as below:
private static final int VOICE_RECOGNIZER_REQUEST_CODE = 0x1008;
public void Recognizera() {
PackageManager pm = getPackageManager();
List<ResolveInfo> activities = pm.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0);
if(activities.size() != 0) {
try {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "語音辨識");
startActivityForResult(intent, VOICE_RECOGNIZER_REQUEST_CODE);
}
catch(Exception e) {
e.printStackTrace();
}
}
}
#Override
protected void onActivityResult(int RequestCode, int ResultCode, Intent data) {
switch(RequestCode) {
case VOICE_RECOGNIZER_REQUEST_CODE:
if(RequestCode == VOICE_RECOGNIZER_REQUEST_CODE && ResultCode == RESULT_OK) {
ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
for(int i = 0; i < results.size(); i++) {
System.out.println("results " + results.get(i));
}
}
break;
}
super.onActivityResult(RequestCode, ResultCode, data);
}
But it show "Unknown problem" as the picture below URL.
But without any error message in logcat.
How to modify it?
This happens because an error was encountered during the voice recognition. The ResultCode parameter will be the error code, one of the errors here. First find what is that error, so you can investigate it further.
