My app is basically a sign language interpreter and I need to remove an error. Here is the code in which there is multiple onactivityresult() definition which is causing error. I do some changes but all in vain. In this code the mobile camera capture image and show a frame in which the user crop the required part of image and show in the next activity.
I'm analyzing this Voice Recognizer class and need help understanding this line in the code. What is the role of the following line? Does it create a list of all of the activities on the android platform loaded on the device? I especially find the resolve info bit confusing...
List activities = pm.queryIntentActivities(new Intent(
Here is the code used in context
package com.example.voicerecognitionactivity;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.app.SearchManager;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;

import android.widget.Toast;
public class VoiceRecognitionActivity extends Activity {
private static final int VOICE_RECOGNITION_REQUEST_CODE = 1001;
private EditText metTextHint;
private ListView mlvTextMatches;
private Spinner msTextMatches;
private Button mbtSpeak;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
metTextHint = (EditText) findViewById(R.id.etTextHint);
mlvTextMatches = (ListView) findViewById(R.id.lvTextMatches);
msTextMatches = (Spinner) findViewById(R.id.sNoOfMatches);
mbtSpeak = (Button) findViewById(R.id.btSpeak);
}
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);
Toast.makeText(this, "Voice recognizer not present",
Toast.LENGTH_SHORT).show();
}
}
public void speak(View view) {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// Specify the calling package to identify your application
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, getClass()
.getPackage().getName());
// Display an hint to the user about what he should say.
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, metTextHint.getText()
.toString());
// Given an hint to the recognizer about what the user is going to say
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,

if (msTextMatches.getSelectedItemPosition() == AdapterView.INVALID_POSITION) {

Toast.LENGTH_SHORT).show();
return;
}

.toString());
// Specify how many results you want to receive. The results will be
// sorted where the first result is the one with higher confidence.
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, noOfMatches);
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.isEmpty()) {
// If first Match contains the 'search' word
// Then start web search.
if (textMatchList.get(0).contains("search")) {
String searchQuery = textMatchList.get(0).replace("search",
" ");
Intent search = new Intent(Intent.ACTION_WEB_SEARCH);
search.putExtra(SearchManager.QUERY, searchQuery);
startActivity(search);
} else {
// populate the Matches
mlvTextMatches
.setAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
textMatchList));
}
}
//Result code for various error.
}else 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);
}
void showToastMessage(String message){
Toast.makeText(this, message, Toast.LENGTH_SHORT).show();
}
}
This, i think, is the simplest way of checking if voice recognition is present or not:
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(),
"Opps! Your device doesn't support Speech to Text",
Toast.LENGTH_LONG);
t.show();
}
ANd after that:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_SPEECH: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> text = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
et_task_notes.setText(text.get(0));
}
break;
}
}
}
Hey I am new to android and eclipse environment.I've no idea of Java.I'm trying to create an app to open the camera of an android device.This is how my main activity.java looks like
package com.example.trycamera2;

public class MainActivity extends Activity {
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100;
private Uri fileUri;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button_send);*****
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File dir = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/xray");
dir.mkdirs();
File file = new File(dir, "tmp_avatar_"
+ String.valueOf(System.currentTimeMillis()) + ".jpg");
fileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
}
});
};
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Bitmap tempBitmap = (Bitmap) data.getExtras().get("data");
FileOutputStream out;
try {
out = new FileOutputStream(fileUri.getPath());
tempBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
Log.v("ManageImage-other", "another phone type");
e.printStackTrace();
}
// Image captured and saved to fileUri specified in the Intent
Toast.makeText(this, "Image saved to:\n" +
data.getData(), Toast.LENGTH_LONG).show();
} else if (resultCode == RESULT_CANCELED) {
// User cancelled the image capture
} else {
// Image capture failed, advise user
}
}
}
}
There is a red mark under button_send in the star marked line...it shows an alternative action_settings instead of button_send....but when I replace with action_settings and run the launch is cancelled.Failed to install .apk on emulator..any help will be of great use.
Sounds like Android can't find your button in any of the layouts. Double check your layouts to make sure they're there.
If they are, just go to the Project menu at the top, and select Clean. Select your project, then click Okay. It will take moment to clean and build, but that might fix your issue.
I am trying reading a Pdf file from android app.
It builds an app and there is no error, but when I click the button it doesn't do anything. it looks like the app thinks there is no file.
I need a help because i am quite new to android apps but need to finish this job today or tomorrow. The person doing this is away at the moment.

}
}
}
private Context getContext() {
// TODO Auto-generated method stub
return null;
}
});
}
}
your pdf path is incorrect. change other valid path and then try again. then first try whether you set internet permission.
You can't directly fetch a file in a remote server using new File("http url").
URI uri = new URI("http", "//path/pathtopdf/mypdf.pdf", null);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
Toast.makeText(ReadPDF.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();

I'm not able to edit your post so i have to put this in an answer: could you provide more details about the problem? More precisely, what do you mean by "the button is not working?" Is anything happening when you click the button, or not? If nothing happens, might be that you run into the ActivityNotFoundException. Since it is catched, but no action is taken, it's transparent. Have you tried debugging, with a break point on the onClick method?
