I'm trying to take a picture with my app, save it and retrieve the url. Currently I have:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, TAKE_PICTURE);
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode)
{
case TAKE_PICTURE:
{
if (resultCode == RESULT_OK)
{
File file = new File(getPath(data.getData()));
Date dt = new Date(file.lastModified());
String datum = dt.toLocaleString();
Comment_Resource photo = new Comment_Resource(file.getAbsolutePath(), datum, true);
}
break;
}
}
}
this works on some phones but a lot of phones don't save the picture causing a nullpointer.
try this:
Uri uri = Uri.fromFile(file);

I have created two edit texts. And i created two buttons. By clicking on a button, it will ask for user to speak and it will convert the speech to text and it will
be displayed in the edit text.
I have called the voice to text function two times. One for first edit text and other for second edit text. But it displaying the error.
Please help me to solve this problem.
Here is my code:
private void promptSpeechInput1() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput1.setText(result.get(0));
}
break;
}
}
}
//////////////
private void promptSpeechInput2() {
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
getString(R.string.speech_prompt));
try {
startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
}
/**
* Receiving speech input
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput2.setText(result.get(0));
}
break;
}
}
}
And the error shows on the line:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
You are redefining the onActivityResult method. Use only one instance for your purpose
/**
* Receiving speech input and output
* */
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case REQ_CODE_SPEECH_INPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput1.setText(result.get(0));
}
break;
}
case REQ_CODE_SPEECH_OUTPUT: {
if (resultCode == RESULT_OK && null != data) {
ArrayList<String> result = data
.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
txtSpeechInput2.setText(result.get(0));
}
break;
}
}
}
and modify this in your promptSpeechInput2 method. Use different request code i.e. not REQ_CODE_SPEECH_INPUT else use REQ_CODE_SPEECH_OUTPUT with different value
try {
startActivityForResult(intent, REQ_CODE_SPEECH_OUTPUT);
} catch (ActivityNotFoundException a) {
Toast.makeText(getApplicationContext(),
getString(R.string.speech_not_supported),
Toast.LENGTH_SHORT).show();
}
I have this code :
public static final int RESULT_OK = -1;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri fileUri = data.getData();
File F = new File(fileUri.getPath());
Log.d("File", "File Uri: " + fileUri.toString());
Intent intent = new Intent(getContext(),activity_file_sharing.class);
intent.putExtra("Filepath", fileUri.toString());
startActivity(intent);
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
F.length() always return 0 i need to path the size of the selected file to the other activity
can anyone help
Please, check this link:
how do I get file size of temp file in android?
Try this:
File file = new File(selectedPath);
int file_size = Integer.parseInt(String.valueOf(file.length()/1024));
I have this code :
Activity 1
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case FILE_SELECT_CODE:
if (resultCode == RESULT_OK) {
// Get the Uri of the selected file
Uri fileUri = data.getData();
Log.d("File", "File Uri: " + fileUri.toString());
Intent intent = new Intent(getContext(),activity_file_sharing.class);
intent.putExtra("Filepath", fileUri);
startActivity(intent);
}
break;
}
super.onActivityResult(requestCode, resultCode, data);
}
In activity_file_sharing
Bundle extras = getIntent().getExtras();
if (extras != null && extras.containsKey("Filepath")) {
FPath = Uri.parse(getIntent().getStringExtra("Filepath").toString());
}
FPath = Uri.parse(getIntent().getStringExtra("Filepath").toString());
I am always getting a null reference on the line above , i can't figure out what is the problem
I hope you guys can help
Save it as a String:
Intent intent = new Intent(getContext(),activity_file_sharing.class);
intent.putExtra("Filepath", fileUri.toString());
startActivity(intent);
I'm trying to save a photo that I have already captured in my application (to use it later like as an icon for my contact) but I don't know if I must change it from uri to bitmap or any other type. I would like to save it as a .png like my others photos
Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT);
galleryIntent.setType("image/*");
startActivityForResult(galleryIntent, 1020);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1020 && resultCode == RESULT_OK) {
mImageUri = data.getData();
Uri mImageUri2 = mImageUri;
Uri aux1=mImageUri;
Bitmap foto = photoUtils.getImage(aux1);
Drawable fotofinal =new BitmapDrawable(getResources(),foto);
Thanks for the help.
I'm having trouble using the camera when there's no sdcard present.
When there is an sdcard, using the camera is trivial, e.g.
http://www.vogella.com/articles/AndroidCamera/article.html + a plethora of other examples.
However, I need to make my app available to devices which don't have SD cards, (e.g. the Sony Xperia series.) I've tried modifying the code such that I'm using the internal storage (I think):
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(getDir("myDirec", Context.MODE_WORLD_WRITEABLE), "tmp_photo_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
file.createNewFile();
mImageCaptureUri = Uri.fromFile(file);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
intent.putExtra("return-data", true);
However, upon result:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intentReturn) {
if (resultCode != RESULT_OK)
return;
String path = mImageCaptureUri.getPath();
Bitmap bitmap = BitmapFactory.decodeFile(path);
...
bitmap is null.
Which leads me to believe that there's some permissions issue....maybe?
I've tried some of the other internal storage options, http://developer.android.com/guide/topics/data/data-storage.html#filesInternal e.g. getFilesDir() but the same result: null bitmap.
Has anyone had any success in using the camera without an sdcard?
Try this. It works..
private Uri imageUri;
public void onClick(View arg0) {
switch (arg0.getId()) {
case R.id.btnImageCapture:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File dir = context.getDir("directory", Context.MODE_PRIVATE);
File photo = new File(dir, "Pic.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photo));
imageUri = Uri.fromFile(photo);
startActivityForResult(intent, OPEN_CAMERA);
break;
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case OPEN_CAMERA:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImage = imageUri;
getContentResolver().notifyChange(selectedImage, null);
ImageView imageView = (ImageView) findViewById(R.id.ImageView);
ContentResolver cr = getContentResolver();
Bitmap bitmap;
try {
bitmap = android.provider.MediaStore.Images.Media
.getBitmap(cr, selectedImage);
imageView.setImageBitmap(bitmap);
Toast.makeText(this, selectedImage.toString(),
Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT)
.show();
}
}
}
}
