My API Version is 24

I'm using Camera and Bluetooth. And my device communicating other device.

The first function is, I'm going to call up the camera app from my app, take a picture and send it to other device.

The second function is, I want to import the file I want to send and send it to another device through Bluetooth.

These two can be run on different projects, but two cannot be executed within one project.

this is my error "Caused by: android.os.FileUriExposedException: file:///sdcard/Download/example.txt exposed beyond app through ClipData.Item.getUri()"

I'll put a piece of the code up.

CameraActivity.class

private void sendTakePhotoIntent() 
 Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 if (takePictureIntent.resolveActivity(getPackageManager()) != null) 
 try 
 photoFile = createImageFile();
 catch (IOException ex) 
 // Error occurred while creating the File
 

 if (photoFile != null) 
 photoUri = FileProvider.getUriForFile(this, getPackageName(), photoFile);
 takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
 startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);

 
 

Bluetooth.class

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
 if (resultCode == DISCOVER_DURATION && requestCode == REQUEST_BLU) 
 Intent i = new Intent();
 i.setAction(Intent.ACTION_SEND);
 i.setType("*/*");
 File file = new File(exist);

 i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));

 PackageManager pm = getPackageManager();
 List<ResolveInfo> list = pm.queryIntentActivities(i, 0);
 if (list.size() > 0) 
 String packageName = null;
 String className = null;
 boolean found = false;

 for (ResolveInfo info : list) 
 packageName = info.activityInfo.packageName;
 if (packageName.equals("com.android.bluetooth")) 
 className = info.activityInfo.name;
 found = true;
 break;
 
 

 if (!found) 
 Toast.makeText(this, "Bluetooth not been found", Toast.LENGTH_LONG).show();
 else 
 i.setClassName(packageName, className);
 startActivity(i);
 
 
 else 
 Toast.makeText(this, "Bluetooth is cancelled", Toast.LENGTH_LONG).show();
