I need your help.
I'm starting to create an app, and I would save photos, videos, vocal memo etc. like a post/note and everything are part of this post.
These multimedia files, will be saved in a folder, which name is a timestamp. On this way, every post/note is charaterized by the timestamp. The timestamp should update every time when I want to create a new post.
I want to save my files by following this path:
Name_app
Timestamp
Pictures
Pictures1
Pictures2
...
Videos
Video1
...
Below my code.
This is the code which create my Image File (and it look like to work):
private File createImageFile () throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File root = new File(Environment.getExternalStorageDirectory().toString());
File myDir = new File(root + "/Urban_stories_sharing/" + timeStamp + "/Pictures");
if (!myDir.exists()) {
myDir.mkdirs();
}
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
myDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
This is the code which start the activity:
public void goToCamera(View v) {
getCameraPermission();
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
File photoFile = null;
try {
isStoragePermissionGranted();
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.andreacarubelli.urbanstoriessharing.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
I think that the problem is on "Uri photoURI = FileProvider.getUriForFile(this,
"com.example.andreacarubelli.urbanstoriessharing.fileprovider",
photoFile);"
This is the code of my path (and I don't know how to change it dynamically like this -> "Urban_stories_sharing/" + timeStamp + "/Pictures"):
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Urban_stories_sharing/Pictures" />
</paths>
This is my provider in my Android Manifest:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.andreacarubelli.urbanstoriessharing.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths">
</meta-data>
</provider>
Thank you so much.

In my app, trying to capture images using the camera app.
I am updating my app to use FileProvider.getUriForFile when specifying the file path to save images to, as Uri.fromFile is deprecated.
It was working fine beforehand using Uri.fromFile. But I can't get it to work using FileProvider.getUriForFile.
I am creating the image file as follows:
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 */
);
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
return image;
Then, depending on the target sdk, I get the image URI:
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
jobImageURI = Uri.fromFile(photoFile);
} else {
jobImageURI = FileProvider.getUriForFile(OrderDetails.this, BuildConfig.APPLICATION_ID + ".provider",photoFile);
}
I have updated the app manifest xml to include the provider, as per the android developer documentation.
I have a provider_paths.xml file which holds the path:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
Then I launch the camera:
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, jobImageURI);
startActivityForResult(takePictureIntent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);
However, after the photo is taken and it comes back to the onActivityResult function, I read back in the image file.
The image isn't saved to the Gallery, as I am reading back in the last file from the Gallery but it isn't there.
I can't access the file using the path from the jobImageURI above either.
Is the path I've provided the provider_paths.xml file incorrect, or why can't I access the images?
try this way
create a xml file under xml folder in res directory
provider_path.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images"
path="Android/data/yourAppPackageName/files/Pictures" />
</paths>
Register Provider in AndroidManifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="yourAppPackageName.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_path"/>
</provider>
add these permissions
<uses-feature android:name="android.hardware.camera"
android:required="true" />
<uses-permission android:name="android.permission.CAMERA"/>
on Camera Button Click call dispatchTakePictureIntent()
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(getActivity().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) {
Uri photoURI = FileProvider.getUriForFile(getActivity(),
"com.arantico.servicepro.provider",
photoFile);
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 = getActivity().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;
}
here mCurrentPhotoPath will show the path of file where it got stored
I am currently trying to create a button the opens the camera app, and saves the picture with a specific name and location.
this is used to create the name/directory
// create a filename for image to be stored into
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String Calib_image_File_Name = "Calibration" + "_" + timeStamp + "STOP";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
Calib_image_File_Name, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
And this is my handler
public void Take_Image_calib(View view)
{
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;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
// ...
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(this,
"com.example.android.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
}
}
}
The issue i have is that after the "STOP" , it adds a 19 digit number afterwards. i don't know why this is happening, advice?
EDIT:
File provider
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.android.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths"></meta-data>
</provider>
This is happening because of the createTempFile in its definition it has this line:
...new File(tmpDirFile, prefix + tempFileRandom.nextInt() + suffix);
which I believe causes the problem. Simply use new File(...):
File image = new File(storageDir, Calib_image_File_Name + ".jpg");
Edit
My functions now look like this:
p
If uou want to save image in your external storage use Externalstoragepublicdirectory function.
This intent expects the EXTRA_OUTPUT location in Uri format, see https://developer.android.com/reference/android/provider/MediaStore.html#ACTION_IMAGE_CAPTURE. Some devices may understand an absolute file path, but this is not the documented behavior.
You can use getExternalMediaDirs() to avoid many permission restrictions.
I have made some changes to your code:
Add this to you application level in your Manifest:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example.android.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths" />
</provider>
Then create file_paths.xml file:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-cache-path name="my_cache" path="." />
<external-path name="my_images" path="Pictures/" />
</paths>
Then in your code:
private static final String FILE_PROVIDER_AUTHORITY = "com.example.android.fileprovider";
private String mTempPhotoPath;
public void takePhoto() {
// Create the capture image intent
Intent imageCapture= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (imageCapture.resolveActivity(getPackageManager()) != null) {
// Create the temporary File where the photo should go
File photoFile = null;
try {
photoFile = createTempImageFile(this);
} catch (IOException ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
// Get the path of the temporary file
mTempPhotoPath = photoFile.getAbsolutePath();
// Get the content URI for the image file
Uri imageUri = FileProvider.getUriForFile(this,
FILE_PROVIDER_AUTHORITY,
photoFile);
// Add the URI so the camera can store the image
imageCapture.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
}
static File createTempImageFile(Context context) throws IOException {
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss",
Locale.getDefault()).format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = context.getExternalCacheDir();
return File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
}
//To save image
String mCurrentPhotoPath = null;
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "IMG_" + timeStamp + "_";
File storageDir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/DCIM/Camera");
Log.d(TAG, "createImageFile: Saving image to:" + storageDir);
File image = new File(storageDir, imageFileName);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
//Return the saved image
return mCurrentPhotoPath ;
}
I am in trouble with this issue, couldn't find any way out yet.
I have configured a Fileprovider in manifest.
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.package.name.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths" />
</provider>
where the #xml/file_paths is like
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-files-path
name="my_images"
path="Android/data/com.package.name/files/Pictures" />
<external-files-path
name="my_images_" />
</paths>
And my java code is like below
private void selectImageFromCamera() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.resolveActivity(getActivity().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
Log.e("selectImageFromCamera", "Error: " + ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {
try {
Uri photoURI = FileProvider.getUriForFile(getActivity(),
"com.package.name.fileprovider",
photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST);
} catch (Exception e) {
e.printStackTrace();
Log.e("selectImageFromCamera", "Error: " + e);
}
}
}
The method createImageFile()
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.US).format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getActivity().getExternalFilesDir(Environment.DIRECTORY_PICTURES);
Log.e("storageDir", "storageDir: " + storageDir.getAbsolutePath());
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
myCurrentPhotoPath = image.getAbsolutePath();
return image;
}
But I am always getting problem when creating photoUri, to be exactly at below line.
Uri photoURI = FileProvider.getUriForFile(getActivity(),
"com.package.name.fileprovider",
photoFile);
Error in try catch
.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Android/data/com.package.name/files/Pictures/JPEG_20170417_115925_834197983.jpg
Any help would be appreciated. Thanks.
I am going to take a photo from Camera in Xamarin Android.
Here's what I did in Xamarin.
Start Camera Activity
private void CallTakePictureIntent ()
{
Intent takePictureIntent = new Intent (MediaStore.ActionImageCapture);
// Ensure that there's a camera activity to handle the intent
if (takePictureIntent.ResolveActivity (PackageManager) != null) {
// Create the File where the photo should go
Java.IO.File photoFile = null;
try {
photoFile = ImageHelper.CreateImageFile (this);
} catch (Exception ex) {
System.Console.WriteLine (ex.ToString ());
}
// Continue only if the File was successfully created
if (photoFile != null) {
sURI photoURI = FileProvider.GetUriForFile (this, UIHelper.FileProvider, photoFile);
requestedAvatarUri = photoURI;
takePictureIntent.PutExtra (MediaStore.ExtraOutput, photoURI);
StartActivityForResult (takePictureIntent, REQUEST_TAKE_PICTURE);
}
}
}
Create temporary file.
public static Java.IO.File CreateImageFile (Context context)
{
// Create an image file name
string timeStamp = DateTime.Now.ToString ("yyyyMMdd_HHmmss");
string imageFileName = "JPEG_" + timeStamp + "_";
Java.IO.File storageDir = context.GetExternalFilesDir (Android.OS.Environment.DirectoryPictures);
Java.IO.File image = Java.IO.File.CreateTempFile (
imageFileName, /* p refix */
".jpg", /* suffix */
storageDir /* directory */
);
return image;
}
Android.Manifest
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.masterbee.xamapp-dev.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/file_paths" />
</provider>
xml/file_paths.xml
<external-path name="external_images" path="Pictures/" />
I think I've done correctly, all things work except runtime exception in FileProvider.GetUriForFile() line.
Here's call trace.
