failed to try to share file via fileprovider, I don't know what I'm doing wrong. mistake (java.lang.IllegalArgumentException: Failed to find configured root that contains /storage/emulated/0/Download/Teste2.txt).
I tried to use the code according to the link: https: //developer.android.com/reference/androidx/core/content/FileProvider and I was not successful
in the previous versions without the fileprovider it worked perfectly using Intent.EXTRA_STREAM now in the android version 11 I was unable to make it work anymore
my code down

When trying to open a file (when choosing an app to open it - like Docs or HTML reader) we get error File Not Found.
We saw that filePathh and fileUri are different and are not pointing to the same location.

For Uri path:

Any help would be appreciated. Thank you.
You can do it alternatively using Bitmap.
//The method below is opened when button is clicked you can handle in your own way
private void OpenImageChooser() {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
//on Activity result will give you the data when you can convert it into bitmap to show in the image view
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
imgAttendance.setImageBitmap(imageBitmap);
}
}
}
In AndroidMenifest.xml
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="#xml/provider_paths" />
</provider>
provider_paths.xml
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="external_files" path="."/>
</paths>
In OnclickListener after file create
if (Build.VERSION.SDK_INT >= 24)
mImageCaptureUri = FileProvider.getUriForFile(EditorActivity.this, BuildConfig.APPLICATION_ID + ".provider", f);
else
mImageCaptureUri = Uri.fromFile(f);
Here is code snippet to get Uri from file provider.
File imageFile = createImageFile();
picUri = FileProvider.getUriForFile(RegisterActivity.this , this.getApplicationContext().getPackageName() + ".provider", imageFile);
Below is file provider path
provider_paths.xml
file.
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="."/>
</paths>
Here <external-path> define that image save in external storage
And below shows how to define file provide in Manifest file.
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">

i am using this code to run a camera intent to take a photo. All being taken from HERE step by step (full sized camera option)
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) {
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.example.android.fileprovider", 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, ".jpg",storageDir);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = "file:" + image.getAbsolutePath();
Toast.makeText(getActivity(), mCurrentPhotoPath, Toast.LENGTH_SHORT).show();
return image;

A little surprising since the file "shell" is there(at this location).
I fount THIS thread but i cant understand a thing...can you explain it humanlike? Any solution is welcome! Its an important project and i need to finish as much as possible and this is a huge stop.
In your files_path.xml, you need to replace com.example.package.name with your apps package name, as explained on developers site.
<?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/com.example.terrormachine.swipeapp/files/Pictures" />
</paths>
Also add camera permission in your AndroidManifest.xml file.
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera"
android:required="true" />
I think you are missing "uses-feature android:name="android.hardware.camera" android:required="true"" in your manifest.

I am sure this is simple but I cannot figure it out. All I am trying to do is send a message via NFC (android Beam) and open my App on the receiver device. I did test my code on a new Project and it worked perfectly but if I try it on my real Project it just start "New Tag collected" and shows application/eu.freemoser.mydebts2go (see my screenshot). I don't know what's wrong maybe something with the manifest? The Google results doesn't match with my problem (or I am just to stupid) but I believe I found some related answer unfortunately I still was not able to solve my problem

Android's MIME type matching for intent filters is case-sensitive (eventhough the MIME types themselves are not). Therefore, with Android (and also pretty much everywhere you use them) you should stick to the convention to use MIME types with lowercase letters only.
Specifically with MIME type records received over NFC, Android will automatically convert them to all-lowercase letters to overcome the problem of case-sensitivity in intent filters. So in your example, changing the type name in the intent filter to "application/eu.freemoser.mydebts2go" should work:
<intent-filter>
<action android:name="android.nfc.action.NDEF_DISCOVERED"/>
<category android:name="android.intent.category.DEFAULT"/>
<data android:mimeType="application/eu.freemoser.mydebts2go"/>
</intent-filter>
In addition, you should also make sure you send the MIME type in lowercase letters only:
NdefMessage msg = new NdefMessage(
new NdefRecord[]{createMimeRecord(
"application/eu.freemoser.mydebts2go", text.getBytes())});
