I'm building an Android Application that has a button, and when the user click it he has to pick an image, from gallery or camera, that will be sent to my server.
But when I try to test it in the emulator, when I submit I encountered the following error:
12-30 17:44:14.435: W/System.err(4216): java.io.FileNotFoundException:
/content:/com.android.providers.media.documents/document/image%3A14: open failed: ENOENT
(No such file or directory)
The error is there:
FileBody cbFile = new FileBody(this.image, "image/*");
And this.image is the image that was picked from the gallery.
I have done something similar to this in one of my apps. Try this to see if it works.
This is the code to open the gallery to pick an image...
Intent intent = new Intent();
intent.setType("image/jpg");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(
Intent.createChooser(intent, "Select Picture"),
SELECT_PICTURE);
Make sure the following method is in your class because it is called after the gallery activity finishes...
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
selectedImageUri = data.getData();
try {
Bitmap selectedImage = MediaStore.Images.Media.getBitmap(
this.getContentResolver(), selectedImageUri);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
now you can do whatever you want with the Bitmap selectedImage

I want the user to be able to access their gallery (by clicking the add photo ImageView), upload a photo of their choosing, and display that photo in the circular profile photo spot. I can't seem to find any definitive guides on how to do this. What is the easiest/best way to go about it? (in Java).
(I would have commented, but I can´t, since I do not have 50 rep.)
You might wanna check:
Get Image from the Gallery and Show in ImageView
(Keep in mind that this is only about loading the Image, saving would need some extra)
Cheers!
you can use this to pick your photo:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, RESULT_LOAD_IMG);
and below code is your on activity result:
#Override
protected void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
if (resultCode == RESULT_OK) {
try {
final Uri imageUri = data.getData();
final InputStream imageStream = getContentResolver().openInputStream(imageUri);
final Bitmap selectedImage = BitmapFactory.decodeStream(imageStream);
image_view.setImageBitmap(selectedImage);
} catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(PostImage.this, "Something went wrong", Toast.LENGTH_LONG).show();
}
}else {
Toast.makeText(PostImage.this, "You haven't picked Image",Toast.LENGTH_LONG).show();
}
}
i'm writing an android app on java and need to let my users select and crop images from the gallery.
There is no problem when choosing an image from any native gallery, but when a user chooses to eater crop or choose an image from google photos app the app crushes.
I cannot figure out what is the source of the problem so any answer will be helpful
this is the code i'm using
class fields:
private Uri imageUri;
opening the camera:
private void camOpen() {
Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(Environment.getExternalStorageDirectory(), "file" + String.valueOf(System.currentTimeMillis()) + ".png");
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
imageUri = Uri.fromFile(f);
i.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
i.putExtra("return-data", true);
startActivityForResult(i, CAMERA_CODE);
}
opening the gallery:
private void galleryOpen() {
Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(Intent.createChooser(i, "select file"), SELECT_PHOTO_CODE);
}
cropping the image:
private void cropImage() {
try {
Intent cropIntent = new Intent("com.android.camera.action.CROP");
cropIntent.setDataAndType(imageUri, "image/*");
cropIntent.putExtra("crop", true);
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("return-data", true);
startActivityForResult(cropIntent, CROP_CODE);
} catch (Exception e) {}
}
the result handler:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAMERA_CODE && resultCode == Activity.RESULT_OK) {
cropImage();
} else if (requestCode == SELECT_PHOTO_CODE && resultCode == Activity.RESULT_OK) {
if (data != null) {
imageUri = data.getData();
cropImage();
}
} else if (requestCode == CROP_CODE && resultCode == Activity.RESULT_OK) {
Bundle bundle = data.getExtras();
Bitmap b = bundle.getParcelable("data");
hasImageChanged=true;
ivProfilePic.setImageBitmap(b);
capturedImage = b;
}
}
thank you for any useful help...
Android does not support crop intent because croping is not part of android api.
So i recommend you for Using library
the issue was with the crop intent. I ended up using the uCrop library and it fixed the problem.
Everything works fine except image updation! When I register a new user and when I click in the image, it opens my image gallery, I choose any image, and it back to register activity but it won't update. Also I'm unable to register because that image is not uploading successfully and we sat if imagepath == null, show that's why toast error is coming that fill all the details.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == PICK_IMAGE && requestCode == RESULT_OK && data.getData() !=null){
imagePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), imagePath);
userProfilePic.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
NOTE:
I tried multiple images, same issue.
There is no error in logcat.
Default image is showing perfectly when we first time try to register that time we sat android logo which is a default.
I can't register without selecting any image because image path == null.
No problem of image size.
Guys, any solution?
I have these codes to get an image from gallery or take photo with camera and after cropping it i want to show it in a bitmap imageview.
My problem is they work good in some devices and don't work in others!
please tell me which part of my code is making the problem ! Thank you
For example:
On LG G4 i not able to crop , but the photo from gallery and camera shows on image view
On Samsung Galaxy Alpha i can crop , image from camera shows good but i cant choose from gallery!
What should i do to work fine in all devices?
private void showFileChooser() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
// ******** code for crop image
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("cropped-rect", "true");
try {
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent,
"Complete action using"), PICK_FROM_GALLERY);
} catch (ActivityNotFoundException e) {
// Do nothing for now
}
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
private void captureWithCamera() {
// call android default camera
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT,
MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
// ******** code for crop image
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("cropped-rect", "true");
try {
intent.putExtra("return-data", true);
startActivityForResult(Intent.createChooser(intent,"Complete action using"), PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
// Do nothing for now
}
}
I think the problem must be in how i handle the returned data in onActivityResult method! Please take a look at my code:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_FROM_GALLERY && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath = data.getData();
try {
//Getting the Bitmap from Gallery
bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
//Setting the Bitmap to ImageView
imageView.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
if (requestCode == PICK_FROM_CAMERA) {
Bundle extras = data.getExtras();
if (extras != null) {
//Bitmap photo = extras.getParcelable("data");
bitmap = extras.getParcelable("data");
imageView.setImageBitmap(bitmap);
}
}
}
Possible solutions would be to put uri with imageChooser's intent. Like this;
private void showCamera() {
try {
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "DCIM");
if (!file.exists()) {
file.mkdirs();
}
File localFile2 = new File(file + File.separator + "IMG_" + String.valueOf(System.currentTimeMillis()) + ".jpg");
imageUri = Uri.fromFile(localFile2);
Intent cameraIntent = new Intent("android.media.action.IMAGE_CAPTURE");
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
cameraIntent.setClipData(ClipData.newRawUri(null, Uri.fromFile(localFile2)));
}
startActivityForResult(cameraIntent, REQUEST_CAMERA);
} catch (Exception localException) {
Toast.makeText(ActivityAddMemory.this, "Exception:" + localException, Toast.LENGTH_SHORT).show();
}
}
On selecting from gallery, complete data is returned with intent. You can use uri by accessing intent.getData() or thumbnail Bitmap using intent.getExtras().get("data"). Don't use imageUri that you passed with that intent.
On capturing from camera, in some devices intent is not null, but it's data is null. And in some devices, intent is null. Check both in onActivityResult.
Uri uri;
if (intent == null || intent.getData() == null) {
uri = this.imageUri;
} else {
uri = intent.getData();
}
Use this uri to display/upload your image.
In my app, I open the camera and want to save that file with a specific name.
I use this code:
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File("new-photo-name.jpg")) );
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
protected void onActivityResult1(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
Bitmap image = (Bitmap) data.getExtras().get("data");
}
}
It does open the camera, I can take and save the photo, but it does not give the good name.
Everytime when I save the picture, he gives the picture an other name, 1 name example is: "13333675392558.jpg". I don't understand how he comes with that kind of numbers.
Why does my code does not apply the name: "new-photo-name.jpg" ?
And/Or what do I wrong then?
Thanks already, Bigflow
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
is the line that sets the filename. It's this line you must change.
I got it working, but don't know the exact same problem yet, but this code worked for me:
private Uri outputFileUri;
public void onLongPress(MotionEvent e) {
// TODO Auto-generated method stub
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(), "/DCIM/Camera/new-photo-name.jpg");
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
onLongPress has something to do with gesture (touch) actions, you could also use a button here.
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE){
System.out.println("string of file name = "+outputFileUri.toString());
}
}
Really small code, but works like a charm
