i'm trying to capture image with android native camera, the save image is good but doesnt contain the usual EXIF data (gps tags, orientation...)
what do i need to do to save also the EXIF?
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(android.provider.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 photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,Uri.fromFile(photoFile));
imageuri = Uri.fromFile(photoFile);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
}
}
/*Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);*/
}
}
#SuppressLint("SimpleDateFormat")
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
}
Following is the method to Save an Image with EXIF Data (Location Data) to Gallery:
private String saveToGallery (Bitmap bitmapImage){
ContextWrapper cw = new ContextWrapper(getApplicationContext());
// path to Directory
String photoDir = Environment.getExternalStorageDirectory() + "/" + Environment.DIRECTORY_DCIM + "/";
File directory = new File(photoDir);
// Creates image file with the name "newimage.jpg"
File myfilepath = new File(directory, "newimage.jpg");
FileOutputStream fos = null;
try {
fos = new FileOutputStream(myfilepath);
// Use the compress method on the BitMap object to write image to the OutputStream
bitgallery.compress(Bitmap.CompressFormat.JPEG, 80, fos);
fos.flush();
fos.close();
myfilepath.setReadable(true, false);
} catch (Exception e) {
e.printStackTrace();
}
Uri bitmapUri = Uri.fromFile(myfilepath);
String currentImageFile = bitmapUri.getPath();
//Writes Exif Information to the Image
try {
ExifInterfaceEx exif = new ExifInterfaceEx(currentImageFile);
Log.w("Location", String.valueOf(targetLocation));
exif.setLocation(targetLocation);
exif.saveAttributes();
} catch (Exception e) {
e.printStackTrace();
}
// Updating Gallery with the Image (Sending Broadcast to Gallery)
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(currentImageFile);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
return directory.getAbsolutePath();
}
The new image is not parsed, as it should be, by the MediaScanner. This smells like a device-specific bug.
See Image, saved to sdcard, doesn't appear in Android's Gallery app for workarounds.
Here is the function to save the Image,
public static String saveImageInExternalCacheDir(Context context, Bitmap bitmap, String myfileName) {
String fileName = myfileName.replace(' ', '_') + getCurrentDate().toString().replace(' ', '_').replace(":", "_");
String filePath = (context.getExternalCacheDir()).toString() + "/" + fileName + ".jpg";
try {
FileOutputStream fos = new FileOutputStream(new File(filePath));
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, fos);
fos.flush();
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
return filePath;
}

I use this code to save the image in the divice and it is working good
but I have problem with image name, I don't know what to tape here (I download the image from url with picasso).
Here is the code:
void saveMyImage (String appName, String imageUrl, String imageName) {
Bitmap bmImg = loadBitmap(imageUrl);
File filename;
try {
String path1 = android.os.Environment.getExternalStorageDirectory()
.toString();
File file = new File(path1 + "/" + appName);
if (!file.exists())
file.mkdirs();
filename = new File(file.getAbsolutePath() + "/" + imageName
+ ".jpg");
FileOutputStream out = new FileOutputStream(filename);
bmImg.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
ContentValues image = new ContentValues();
image.put(Images.Media.TITLE, appName);
image.put(Images.Media.DISPLAY_NAME, imageName);
image.put(Images.Media.DESCRIPTION, "App Image");
image.put(Images.Media.DATE_ADDED, System.currentTimeMillis());
image.put(Images.Media.MIME_TYPE, "image/jpg");
image.put(Images.Media.ORIENTATION, 0);
File parent = filename.getParentFile();
image.put(Images.ImageColumns.BUCKET_ID, parent.toString()
.toLowerCase().hashCode());
image.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, parent.getName()
.toLowerCase());
image.put(Images.Media.SIZE, filename.length());
image.put(Images.Media.DATA, filename.getAbsolutePath());
Uri result = getContentResolver().insert(
Images.Media.EXTERNAL_CONTENT_URI, image);
Toast.makeText(getApplicationContext(),
"download in " + filename, Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
}
This is the call method in onCreate:
/* button to download the image */
download_image = findViewById(R.id.button_download);
checkPermission();
download_image.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (checkPermission()) {
String URL = intent.getStringExtra("imageUrl");
saveMyImage ("my app",URL,"i want to get the image name from the url");
}
}
});
I want to get the image name from the url, so how can I do that?
Try this:
URI uri = new URI(URL);
URL videoUrl = uri.toURL();
File tempFile = new File(videoUrl.getFile());
String fileName = tempFile.getName();
Im building an android app that needs to fetch an image from an url and, after is done displaying it into the image view, I want to store it in the hard drive of the phone so it can be use later without creating a new petition or depending on the cache.
Im using glide 4.9.0
Some of the solutions online include using some deprecated clases such as SimpleTarget and Target that wont be applicable in this project.
This is what I have so far.
File file = new File(holder.context.getExternalFilesDir(null), fileName);
if (file.exists()) {
GlideApp.with(holder.context).load(file).into(holder.ivProductImage);
} else {
GlideApp.with(holder.context).load(urlImage).into(holder.ivProductImage);
// save the image to the hard drive
}
//Step 1
Glide.with(mContext)
.load(images.get(position).getThumbnail())
.asBitmap()
.into(new Target<Bitmap>(100,100) {
#Override
public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
saveImage(resource,position);
}
});
//Step 2
private String saveImage(Bitmap image, int position) {
String savedImagePath = null;
String imageFileName = "JPEG_" + images.get(position).getName() + ".jpg";
File storageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
+ "/Comicoid");
boolean success = true;
if (!storageDir.exists()) {
success = storageDir.mkdirs();
}
if (success) {
File imageFile = new File(storageDir, imageFileName);
savedImagePath = imageFile.getAbsolutePath();
try {
OutputStream fOut = new FileOutputStream(imageFile);
image.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
// Add the image to the system gallery
galleryAddPic(savedImagePath);
}
return savedImagePath;
}
//Step 3
private void galleryAddPic(String imagePath) {
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
File f = new File(imagePath);
Uri contentUri = Uri.fromFile(f);
mediaScanIntent.setData(contentUri);
mContext.sendBroadcast(mediaScanIntent);
}
I'm trying to put the URIs of both the image and the thumbnail from a camera intent into a SQLite database.
I have the full image inserting just fine. I thought I had the thumbnail going in too but it's actually still the full image going into the database again.
Can I get a bit of guidance on how to go about doing this? I've tried a number of things so far but have been stuck for a couple days on this step.
Here are my relevant methods:
private void dispatchTakePictureIntent() {
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 photoFile = null;
File photoThumbnailFile = null;
try {
photoFile = createImageFile();
photoThumbnailFile = createImageThumbnailFile();
} catch (IOException ex) {
}
// Continue only if the File was successfully created
if (photoFile != null) {
photoURI = FileProvider.getUriForFile(this,
"com.example.jeremy.sqlwine.fileprovider",
photoFile);
photoThumbnailURI = FileProvider.getUriForFile(this,
"com.example.jeremy.sqlwine.fileprovider",
photoThumbnailFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
private File createImageThumbnailFile() throws IOException {
// Create an image thumbnail file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageThumbnailFileName = "THUMBNAIL_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageThumbnailFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoThumbnailPath = image.getAbsolutePath();
return image;
}
//This method will happen when the camera is done taking the picture
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Toast.makeText(this, "Image saved", Toast.LENGTH_SHORT).show();
bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), photoURI);
} catch (IOException e) {
e.printStackTrace();
}
bitmapThumbnail = ThumbnailUtils.extractThumbnail(bitmap,50,50);
imageThumbnail.setImageBitmap(bitmapThumbnail);
}
}
I'm trying to obtain the filepath of my stored Image that's stored like so after using the ACTION_IMAGE_CAPTURE intent:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageOne.setImageBitmap(imageBitmap);
SaveImageOne(imageBitmap);
}
SaveImageFunction
private void SaveImageOne(Bitmap finalBitmap) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
String fname = "Image-1.jpg";
File file = new File (myDir, fname);
if (file.exists ()) file.delete ();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
This way I can store this 'filepath' of the stored File to SharedPreferences to be accessed later on and say passed into the ACTION_SEND as an image attachment.
after this line out.close(); write this line
String pathString = file.getAbsolutePath(); // gives you the path of the file
now use it how you want it
To share the image via Email and mms first step I need to save the image in sdcard but for me the saved image is not getting opened instead "Invalid File" error, I checked with the extension format everything is correct but don't know where I'm going wrong.
Below is the java code.
public class Share extends CordovaPlugin {
public static final String ACTION_POSITION = "ShareImage";
#Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext)
throws JSONException {
if (ACTION_POSITION.equals(action)) {
try {
JSONObject arg_object = args.getJSONObject(0);
Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
sendIntent.setType("image/jpg");
sendIntent.putExtra(android.content.Intent.EXTRA_TEXT, arg_object.getString("image"));
String name = arg_object.getString("image");
String defType = "drawable";
String defPackage = "com.picsswipe";
int drawableId = this.cordova.getActivity().getResources().getIdentifier( name , defType, defPackage );
// Bitmap bbicon = BitmapFactory.decodeFile( arg_object.getString("image") );
Bitmap bbicon = BitmapFactory.decodeResource( this.cordova.getActivity().getResources(),drawableId );
String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
OutputStream outStream = null;
File f = new File(extStorageDirectory + "/Download/",
"jj.jpg" );
try {
outStream = new FileOutputStream(f);
bbicon.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
outStream.flush();
outStream.close();
} catch (Exception e) {
}
File r1 = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/Download/", "jj.jpg");
//RETRIEVING IMAGES FROM SDCARD
Uri uri1 = Uri.fromFile(r1);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri1);
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(r1));
Uri uris = Uri.fromFile(new File(Environment.getExternalStorageDirectory(), "jj.jpg"));
this.cordova.getActivity().startActivity(sendIntent);
} catch (Exception e) {
System.err.println("Exception: " + e.getMessage());
callbackContext.error(e.getMessage());
return false;
}
}
return true;
}
}
File file;
File rootPath = android.os.Environment
.getExternalStorageDirectory();
File directory = new File(rootPath.getAbsolutePath()
+ "/Download");
if (!directory.exists())
directory.mkdir();
file = new File(directory, "filename.PNG");//.png/.jpg anything you want
try {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.pincheck);
FileOutputStream outStream;
outStream = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
outStream.flush();
outStream.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
and you should add this permission in your manifest file..Then only file will copied to your external sd card.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
