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

I'm currently learning how to use android studio in java and am trying to make a social media app. I am currently creating an edit profile page where the user would update their details and upload a profile picture.
I have been following tutorials online and all of the ones I have come across use the startActivityForResult method. It has been crossed out and wont call the method as it is deprecated. But I don't know what to use instead.
`ProfileImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//open gallery
Intent OpenGalleryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(OpenGalleryIntent, 1000);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #androidx.annotation.Nullable Intent data){
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == 1000){
if(resultCode == Activity.RESULT_OK){
Uri imageUri = data.getData();
ProfileImage.setImageURI(imageUri);
UploadImageToFirebase(imageUri);
}
}
}
private void UploadImageToFirebase(Uri image){
StorageReference fileRef = storageReference.child("Profile.jpg");
fileRef.putFile(image).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Toast.makeText(Edit_Profile.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
}
});`
I know there is an alternative but I don't understand how it works.
startActivityForResult is indeed deprecated in later versions of AndroidX Activity and Fragment APIs (while I believe you can still use it despite of warning). New way to get result from activity is registerForActivityResult.
In your code you would need to create a launcher, which will handle result (selected image)
private final ActivityResultLauncher<Intent> launcher = registerForActivityResult(
new ActivityResultContracts.StartActivityForResult(),
result -> {
if (result.getResultCode() == Activity.RESULT_OK
&& result.getData() != null) {
Uri photoUri = result.getData().getData();
//use photoUri here
}
}
);
and then launch this launcher in onClickListener
profileImage.setOnClickListener(view -> {
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
launcher.launch(intent);
});
Yes startActivityForeResult is deprecated.
Now you can use ActivityResultLauncher for the callbacks

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 making an Android application in Android studio where the user can take a photo and save it into a new folder in their gallery. Currently the application takes the pictures fine but doesn't save the image into the new "SOC" folder in my gallery. I'm not getting any errors and I have no idea why it's not saving the image. Any help would be appreciated.
My code is as fallows
static final int REQUEST_IMAGE_CAPTURE = 1;
private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 0;
public void onClickbtnCamera(View v)
{
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
Uri uriSavedImage=Uri.fromFile(new File("/storage/emulated/0/DCIM/SOC","QR_"+timeStamp+ ".png"));
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
startActivityForResult(imageIntent, 1);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1) {
//Check for succesful result code
if (resultCode == -1) {
//Show your Toast when the result is a success.
Toast toast = Toast.makeText(getApplicationContext(),
"Picture is saved in your SOC gallery", Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP | Gravity.CENTER_HORIZONTAL, 100, 0);
toast.show();
}
}
}
I think you must manually add your new photo Uri to Media Content Provider.
take a look here
Call this method in your Activity for result
protected void addPhotoToGallery() {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(getCurrentPhotoPath());
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.getActivity().sendBroadcast(mediaScanIntent);
}
you should save the photo path before launching the intent and then getCurrentPhotoPath() must get that path
in my android application I want to copy file from one directory to another , I have the path of file filePath , and have the path of directory dirPath in what I must copy the file. I tried many ways , but nothing helped , some ways only make some empty(0 kb) file with strange name different from the name of my file. SO help please :)
here is some part of code, if it help's you, I have two buttons for Gallery and for Camera , and I must pick images from there
Button btnCam = (Button) dialog.findViewById(R.id.btncamera);
btnCam.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.cancel();
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, 2500);
}
});
//end of camera button
Button btnGal = (Button) dialog.findViewById(R.id.btngalary);
btnGal.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
dialog.cancel();
Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
and Activity Result
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
{
Uri selectedImage = data.getData();
url = new String(selectedImage.toString());
//here I must copy file with path `selectedImage` and replace it in
// directory with path `currentDir.hetPath()`
}
if (requestCode == 2500)
{
Bitmap photo = (Bitmap) data.getExtras().get("data");
imageView.setImageBitmap(photo);
//here I must do the same thing above
}
}
I found some way , in my Activity result I must call copyFile(String, String) function , here is the body
public static boolean copyFile(String from, String to) {
try {
File sd = Environment.getExternalStorageDirectory();
if (sd.canWrite()) {
int end = from.toString().lastIndexOf("/");
String str1 = from.toString().substring(0, end);
String str2 = from.toString().substring(end+1, from.length());
File source = new File(str1, str2);
File destination= new File(to, str2);
if (source.exists()) {
FileChannel src = new FileInputStream(source).getChannel();
FileChannel dst = new FileOutputStream(destination).getChannel();
dst.transferFrom(src, 0, src.size());
src.close();
dst.close();
}
}
return true;
} catch (Exception e) {
return false;
}
}
If you feel up to it, you can include Apache Commons I/O in your app. I don't know how big it is. See Standard concise way to copy a file in Java?
Or maybe you could download the source, and cherry-pick the source to FileUtils.copyFile()
I'm trying to get a program to let the user to import a custom background.
Here's where I'm at:
I have the getDrawable function taking another function as an argument:
mDrawableBg = getResources().getDrawable(getImage());
getImage() is suppose to return a integer referencing the selected image, here is the code (so far) for that function:
public int getImage(){
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 10);
}
This is suppose to open the gallery and let the user select an image. I would then use mDrawableBg to set the background. I'm not sure how to return a reference ID to that selected image though. Any suggestions?
Try this:
String pathName = "selected Image path";
Resources res = getResources();
Bitmap bitmap = BitmapFactory.decodeFile(pathName);
BitmapDrawable bd = new BitmapDrawable(res, bitmap);
View view = findViewById(R.id.container);
view.setBackgroundDrawable(bd);
The way you're attempting to do it is not possible, I'm afraid. One of the things you'll want to learn as a new Android developer is how the cycle between activities works. In your case, you're running an Activity that calls upon an Intent to get data from it. However, in the Android API, an Intent can only be referenced on its own time. This means you can't use your getImage() method the way you had tried.
There is hope, though!
What you first need to do is call the Intent. You will do this through the code you have now in getImage():
public void getImage() { // This has to be a void!
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 10);
}
This method will now start the Image Picker that you want users to select from. Next, you have to catch what is returned. This cannot be returned from your getImage() method, but instead must be collected from elsewhere.
You must implement the below method:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
final int SELECT_PICTURE = 1; // Hardcoded from API
if (requestCode == SELECT_PICTURE) {
String pathToImage = data.getData().getPath(); // Get path to image, returned by the image picker Intent
mDrawableBg = Drawable.createFromPath(pathToImage); // Get a Drawable from the path
}
}
}
Lastly, instead of calling mDrawableBg = getResources().getDrawable(getImage());, just call getImage();. This will initialize the Image Picker.
Some reading:
Android Activity (notably stuff about Intents and getting a result back)
Android Drawable
Getting a Drawable from a path
More on the Image Picker Intent
Good luck!
I'm not sure, but if you mean you don't know how to receive results from that intent, you can use :
#Override
protected void onActivityResult(int requestCode,int resultCode,Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if(resultCode == RESULT_OK)
{
if (requestCode == 10)
{
// DoSomething
}
}
}
