Insert a picture into an imageview - java

In my app, I insert two pictures into two image-views and I use activity for result to fetch the photo from gallery.
private void showFileChooser () {
mHandler.post(new Runnable() {
#Override
public void run() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
});
}
private void showFileChooser2 () {
mHandler.post(new Runnable() {
#Override
public void run() {
Intent intent2 = new Intent();
intent2.setType("image/*");
intent2.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent2, "Select Picture"), PICK_IMAGE_REQUEST2);
}
});
}
#Override
protected void onActivityResult ( int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && 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);
rbitmap = getResizedBitmap(bitmap, 1000);//Setting the Bitmap to ImageView
imageViewUserImage.setImageBitmap(rbitmap);
imageViewUserImage.requestFocus();
} catch (IOException e) {
e.printStackTrace();
}
}else if (requestCode == PICK_IMAGE_REQUEST2 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath2 = data.getData();
try {
//Getting the Bitmap from Gallery
bitmap2 = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath2);
rbitmap2 = getResizedBitmap(bitmap2, 1000);//Setting the Bitmap to ImageView
imageViewUserImage2.setImageBitmap(rbitmap2);
imageViewUserImage2.requestFocus();
} catch (IOException e) {
e.printStackTrace();
}
}
}
The app is doing well but sometimes a weird thing happens.Sometimes once I click the desired photo in gallery, the app returns to the main activity and I find the previous loaded image in the other image-view is deleted.In other words, sometimes loading a picture in one of them deletes the loaded image in the other.
That glitch doesn't happen always, it sometimes happens and sometimes the app works well without any problem.
How can I fix that?

Place a break point in the catch on the 'e.printStackTrace();' line.
Play with the app, and see the reason for failure.
Without any stack trace we can only guess the reason.

I found the problem.The size of the images are kind of large so a "memory is out" error appears.To avoid such problem, I recycled each bitmap within its if case.
private void showFileChooser () {
mHandler.post(new Runnable() {
#Override
public void run() {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
}
});
}
private void showFileChooser2 () {
mHandler.post(new Runnable() {
#Override
public void run() {
Intent intent2 = new Intent();
intent2.setType("image/*");
intent2.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent2, "Select Picture"), PICK_IMAGE_REQUEST2);
}
});
}
#Override
protected void onActivityResult ( int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && 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);
rbitmap = getResizedBitmap(bitmap, 1000);//Setting the Bitmap to ImageView
imageViewUserImage.setImageBitmap(rbitmap);
bitmap.recycle;
imageViewUserImage.requestFocus();
} catch (IOException e) {
e.printStackTrace();
}
}else if (requestCode == PICK_IMAGE_REQUEST2 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri filePath2 = data.getData();
try {
//Getting the Bitmap from Gallery
bitmap2 = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath2);
rbitmap2 = getResizedBitmap(bitmap2, 1000);//Setting the Bitmap to ImageView
imageViewUserImage2.setImageBitmap(rbitmap2);
bitmap2.recycle;
imageViewUserImage2.requestFocus();
} catch (IOException e) {
e.printStackTrace();
}
}

Android Firebase upload image not working

I am trying to use the following code to have a user select an image, and after the image is selected, it is automatically uploaded to my Firebase storage. I initialized the variable storageReference in the OnCreate function
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(requireContext());
builder.setTitle("Add Photo!");
builder.setItems(options, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int item) {
if (options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
startActivityForResult(intent, 1);
}
else if (options[item].equals("Choose from Gallery"))
{
Intent intent = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(intent.createChooser(intent, "Select Image"), 2);
}
else if (options[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
#SuppressLint("LongLogTag")
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// If the image is uploaded properly and the resultcode is OK
// The imagePreview is updated and the image is uploaded
if(requestCode == 1 || requestCode == 2) {
if (resultCode == Activity.RESULT_OK && data != null && data.getData() == null) {
filePath = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(requireContext().getContentResolver(), filePath);
imagePreview.setImageBitmap(bitmap);
uploadImage();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
private void uploadImage()
{
if (filePath != null) {
// Code for showing progressDialog while uploading
ProgressDialog progressDialog = new ProgressDialog(getContext());
progressDialog.setTitle("Uploading...");
progressDialog.show();
// Defining the child of storageReference
StorageReference ref = storageReference.child(mAuth.getCurrentUser().toString());
// adding listeners on upload
// or failure of image
ref.putFile(filePath).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
// Image uploaded successfully
// Dismiss dialog
progressDialog.dismiss();
Toast.makeText(getActivity(), "Image Uploaded!!", Toast.LENGTH_SHORT).show();
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
// Error, Image not uploaded
progressDialog.dismiss();
Toast.makeText(getContext(),"Failed " + e.getMessage(),Toast.LENGTH_SHORT).show();
}
})
.addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() {
// Progress Listener for loading
// percentage on the dialog box
#Override
public void onProgress(UploadTask.TaskSnapshot taskSnapshot) {
double progress = (100.0 * taskSnapshot.getBytesTransferred() / taskSnapshot.getTotalByteCount());
progressDialog.setMessage("Uploaded " + (int)progress + "%");
}
});
}
}
My guess is that the uploadImage function is not being called but I am not sure why.
I figured it out, the issue was with this line
if (resultCode == Activity.RESULT_OK && data != null && data.getData() == null)
data.getData() == null
should be:
data.getData() != null

Capture photo intent resultCode

How can I detect wether the user take picture and selects it (with the confirm button on camera) or they just turn on a camera, take a picture and remove it (with the cancel button on camera)
When the user take picture I am loading that picture into an ImageView. If user hits confirm button then everything is OK but if user don't want that picture and decide to hit cancel button then the ImageView goes blank.
This is my camera intent :
void capturePhoto() {
// ImagePicker.pickImage(this, "Select your image:");
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File f = null;
try {
f = setUpPhotoFile();
mCurrentPhotoPath = f.getAbsolutePath();
Uri photoURI = Uri.fromFile(f);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
} catch (IOException e) {
e.printStackTrace();
f = null;
mCurrentPhotoPath = null;
pictureUri = null;
}
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
And onActivityResult, in both cases the resultCode is always 1. (note that RESULT_OK is -1) and I dont know why.
This is how I set image to ImageView using Glide:
Glide.with(this).load(mCurrentPhotoPath).centerCrop().into(imageView);
Any Suggestions?
Thanks!
you just need to pass if statement in onActivityresult
cause if you use directly that URI or whatever you use which has no any frame set cause user cancel it so just do as given
//if needed than
//public static final int RESULT_OK = -1;
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case REQUEST_TAKE_PHOTO:
//do your stuff here
}
}
You can use below code
static final int REQUEST_IMAGE_CAPTURE = 1;
private void dispatchTakePictureIntent() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
if (isCameraPermissionEnabled()) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}else {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.CAMERA},
1);
}
}
}
public boolean isCameraPermissionEnabled() {
return !(Build.VERSION.SDK_INT >= 23 &&
ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED );
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
mBitmap = (Bitmap) extras.get("data");
imageView.setBackground(new BitmapDrawable(getResources(),mBitmap));
}
}

Image displays when choosing from gallery but not when capturing from camera

On the press of a button, dispatchTakePictureIntent() lets the user choose between taking a picture or choosing one from the gallery four times. These four URIs are stored in an ArrayList and the four should be shown in their respective ImageViews. The problem I'm having is that when I "capture a picture", it doesn't show in the ImageView right away; but the pictures I chose from gallery do.
The picture I captured is properly saved and can be found in "choose from gallery" the next time I press the button. Can anybody see what I'm doing wrong?
takePictureIntent():
private void dispatchTakePictureIntent() {
for(int i = 0; i < 4; i++) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
outputFileUri = Uri.fromFile(photoFile);
} catch (IOException ex) {
Log.w("error","IOException");
}catch (NullPointerException nullEx) {
Log.w("error","NullPointerException");
}
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();

final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
cameraIntents.add(intent);
}
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_OPEN_DOCUMENT);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
if(id.equals(HAPPY_ID))
startActivityForResult(chooserIntent, REQUEST_HAPPY_PHOTO);
if(id.equals(SURPRISED_ID))
startActivityForResult(chooserIntent, REQUEST_SURPRISED_PHOTO);

Try this, this works for me
public Uri captureImage() {
Intent chooserIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (chooserIntent.resolveActivity(getPackageManager()) != null) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "Image File name");
Uri takenImageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intentPicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intentPicture.putExtra(MediaStore.EXTRA_OUTPUT, takenImageUri);
startActivityForResult(intentPicture, MyConstants.REQUEST_IMAGE_CAPTURE);
return takenImageUri;
}
return null;
}
public String getRealPathFromURI(Uri contentUri){
try {
String[] proj = {MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
catch (Exception e){
return contentUri.getPath();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK && data != null) {
switch (requestCode){
case MyConstants.REQUEST_IMAGE_CAPTURE:
if (takenImageUri != null) {
Uri imagePath =getRealPathFromURI(takenImageUri,this));
}
}
}
}
rather than looping for 4 times, why not make each imageView an OnClickListener to get the image one by one?

my imageview have some error anyone have any idea?

i use imageview.onclick for call galley and select picture , frist click image not come to imageview but second click image update i dont know why or have any idea ?
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_GALLERY);
imageView.setImageBitmap(resize);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_GALLERY && resultCode == RESULT_OK) {
Uri uri = data.getData();
try {
bitmap = Media.getBitmap(this.getContentResolver(), uri);
resize = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
} catch (Exception e) {
e.printStackTrace();
}
}
}
Move imageView.setImageBitmap(resize); to onActivityResult
imageView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_GALLERY);
}
});
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_GALLERY && resultCode == RESULT_OK) {
Uri uri = data.getData();
try {
bitmap = Media.getBitmap(this.getContentResolver(), uri);
resize = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, false);
imageView.setImageBitmap(resize);
} catch (Exception e) {
e.printStackTrace();
}
}
}

default camera to take a picture in android

How to use default camera to take a picture in android ?
Uri imageUri;
final int TAKE_PICTURE = 115;
public void capturePhoto(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photoFile = new File(Environment.getExternalStorageDirectory(), "Photo.png");
intent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
imageUri = Uri.fromFile(photoFile);
startActivityForResult(intent, TAKE_PICTURE);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK) {
Uri selectedImageUri = imageUri;
//Do what ever you want
}
}
}
The intent which is used to open the camera is
buttonCapturePhoto.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAPTURE_IMAGE);
}
});
The code which gives you the image after capturing is
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Uri uriImage;
InputStream inputStream = null;
if ( (requestCode == SELECT_IMAGE || requestCode == CAPTURE_IMAGE) && resultCode == Activity.RESULT_OK) {
uriImage = data.getData();
try {
inputStream = getContentResolver().openInputStream(uriImage);
Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null, options);
imageView.setImageBitmap(bitmap);
} catch (NullPointerException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setAdjustViewBounds(true);
}
}
This is a simple example.Anyway this will return the image as a small bitmap.If you want to retrive the full-sized image ,is a bit more complicated.
ImageView takePhotoView = (ImageView) findViewById(R.id.iwTakePicture);
Bitmap imageBitmap = null;
takePhotoView.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
dispatchTakePictureIntent(0);
}
});
private void dispatchTakePictureIntent(int actionCode) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePictureIntent, actionCode);
}
private void handleSmallCameraPhoto(Intent intent) {
Bundle extras = intent.getExtras();
this.imageBitmap = (Bitmap) extras.get("data");
takePhotoView.setImageBitmap(imageBitmap);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(resultCode == RESULT_OK)
handleSmallCameraPhoto(data);
}
