Got similar problem after enabled flavors (dev, stage).

Before flavors my path resource looked like this:

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
    name="my_images"
    path="Android/data/pl.myapp/files/Pictures" />
</paths>

After added android:authorities="${applicationId}.fileprovider" in Manifest appId was pl.myapp.dev or pl.myapp.stage depends on flavor and app started crashing. I removed full path and replaced it with dot and everything started working.

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <external-path
        name="my_images"
        path="." />
</paths>

Your file is stored under getExternalFilesDir    That maps to  lt external-files-path gt   not  lt files-path gt   Also  your file path does not contain images  in it  so the path attribute in your XML is invalid  Replace res xml file paths xml with   lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt paths gt       lt external-files-path name  quot my images quot  path  quot   quot    gt   lt  paths gt    UPDATE 2020 MAR 13 Provider path for a specific path as followings    lt files-path  gt  -- gt  Context getFilesDir    lt cache-path  gt  -- gt  Context getCacheDir    lt external-path  gt  -- gt  Environment getExternalStorageDirectory    lt external-files-path  gt  -- gt  Context getExternalFilesDir String   lt external-cache-path  gt  -- gt  Context getExternalCacheDir    lt external-media-path  gt  -- gt  Context getExternalMediaDirs    Ref  https   developer android com reference androidx core content FileProvider

If you are using internal cache then use    lt paths xmlns android  http   schemas android com apk res android  gt       lt cache-path name  cache  path       gt   lt  paths gt

Be aware that external-path is not pointing to your secondary storage  aka  removable storage   despite the name  external    If you re getting  Failed to find configured root  you may add this line to your XML file    lt root-path name  root  path       gt    See more details here FileProvider and secondary external storage

User · Answer

Check how many storages your device offers - sharing files from secondary storage is not supported  Look at FileProvider java source  from support-core-utils 25 3 1                  else if  TAG EXTERNAL FILES equals tag                     File   externalFilesDirs   ContextCompat getExternalFilesDirs context  null                   if  externalFilesDirs length  gt  0                        target   externalFilesDirs 0                                   else if  TAG EXTERNAL CACHE equals tag                     File   externalCacheDirs   ContextCompat getExternalCacheDirs context                   if  externalCacheDirs length  gt  0                        target   externalCacheDirs 0                                     So  they take only the first storage   Also  you can see that getExternalCacheDirs   is used to obtain list of storages through the ContextCompat interface  See documentation for its limits  it s told to not recognize USB Flashes for example   Best is to make some debug output of list of storages from this API on your own  so that you can check that path to storage matches the path passed to getUriForFile     There s already a ticket assigned  as for 06-2017  in Google s issue tracker  asking to support more than one storage  Eventually  I found SO question on this as well

If your file path is like  storage emulated 0  yourfile   you just need modify your FileProvider xml   lt paths gt       lt external-path name  external  path       gt   lt  paths gt    then call this function when you need share file  Intent sharingIntent   new Intent Intent ACTION SEND                       Uri fileUri   FileProvider getUriForFile getContext                                 com example myapp fileprovider                               file                       sharingIntent setType            any flie type                     sharingIntent putExtra Intent EXTRA STREAM  fileUri                       startActivity Intent createChooser sharingIntent   Share file       it works on android M   Pie

For Xamarin Android users   This could also be the result of not updating your support packages when targeting Android 7 1  8 0   Update them to v25 4 0 2  and this particular error might go away giving you  ve configured your file path file correctly as others stated         Giving context  I switched to targeting Oreo from Nougat in a   Xamarin Forms app and taking a picture with the Xam Plugin Media   started failing with the above error message  so updating the packages   did the trick for me ok

The problem might not just be the path xml   Following is my fix   Looking into the root course in android support v4 content FileProvider SimplePathStrategy getUriForFile         public File getFileForUri Uri uri            String path   uri getEncodedPath             final int splitIndex   path indexOf      1           final String tag   Uri decode path substring 1  splitIndex            path   Uri decode path substring splitIndex   1             final File root   mRoots get tag      mRoots is parsed from path xml         if  root    null                throw new IllegalArgumentException  Unable to find configured root for     uri                                     This means mRoots should contains the tag of requested uri  So I write some code to print mRoots and tag of uri  and then easily find the tags do not match   It comes out that setting provider authority as   applicationID  provider is a stupid idea  This authority is so common that might be used by other providers  which will mess up the path config

This confusing me a bit too   The problem is on  path  attribute in your xml file   From this document FileProvider  path  is a subdirectory  but in another document  camera photobasics  shown  path  is full path    lt  xml version  1 0  encoding  utf-8   gt   lt paths xmlns android  http   schemas android com apk res android  gt       lt external-path name  my images  path  Android data com example package name files Pictures    gt   lt  paths gt    I just change this  path  to full path and it just work

I see that at least you re not providing the same path as others in file paths xml  So please make sure you provide the exact the same package name or path in 3 places including    android authorities attribute in manifest path attribute in file paths xml authority argument when calling FileProvider getUriForFile

My issue was that I had overlapping names in the file paths for different types  like this    lt cache-path     name  cached files      path       gt   lt external-cache-path     name  cached files      path       gt    After I changed the names   cached files   to be unique  I got rid of the error  My guess is that those paths are stored in some HashMap or something which does not allow duplicates

This Worked for me as well Instead of giving full path i gave path  Pictures  and it worked fine    lt  xml version  1 0  encoding  utf-8   gt    lt paths gt     lt external-files-path     name  images      path  Pictures  gt     lt  external-files-path gt    lt  paths gt

If nothing helps and you are getting the error  failed to find configured root that contains  data data       then try changing some line like   File directory   thisActivity getDir  images   Context MODE PRIVATE     to   File directory   new File thisActivity getFilesDir     images      and in the xml file    lt files-path name  files  path       gt    which is weird  since the folder I access is  images

I noticed that the policy or behaviour regarding the path xml file changed between Support Library 26 and 27  For capturing a picture from the camera  I saw the following changes     With 26  I had to use  lt external-path gt  and the full path given in the path argument  With 27  I had to use  lt external-files-path gt  and only the subfolder in the path argument    So what specifically worked for me with Support Library 27 as the path xml file was    lt  xml version  1 0  encoding  utf-8   gt   lt paths gt       lt external-files-path name  camera image  path  Pictures    gt   lt  paths gt

It depends what  kind of storage you want to do  INTERNAL or EXTERNAL  for EXTERNAL STORAGE    lt  xml version  1 0  encoding  utf-8   gt   lt paths gt       lt external-files-path name  my images  path  my images    gt   lt  paths gt    but for INTERNAL STORAGE  be careful with the path  because it uses getFilesDir   method which mean that your file will be located in the root directory for the app          File storeDir   getFilesDir       path       So your provider file must be like this    lt paths gt       lt files-path name  my images  path       gt   lt  paths gt

Android official document says file paths xml should have     lt  xml version  1 0  encoding  utf-8   gt   lt paths xmlns android  http   schemas android com apk res android  gt          lt external-path name  my images              path  Android data com example package name files Pictures    gt   lt  paths gt       But to make it work in the latest android there should be a     at the end of the path  like this     lt  xml version  1 0  encoding  utf-8   gt   lt paths xmlns android  http   schemas android com apk res android  gt          lt external-path name  my images              path  Android data com example package name files Pictures     gt   lt  paths gt

I have spent 5 hours for this    I have tried all the methods above but it depends on the what storeage your app currently using    https   developer android com reference android support v4 content FileProvider GetUri  Check the documentation before trying the codes    In my case  since files-path sub directory will be Context getFilesDir    The funky thing is it Context getFilesDir   notes one another subdirectory    what I am looking for is   data user 0 com psh mTest app imageDir 20181202101432629 png  Context getFilesDir     returns   data user 0 com psh mTest files  so the tag should be       files-path name  app imageDir  path     app imageDir           Then it works
