IllegalArgumentException: Failed to find configuration root that contains xxx on FileProvider.getUriForFile
android, android-fileprovider, filepath, illegalargumentexception
Solution
The path of that file begins exactly with what getExternalFilesDir(Environment.DIRECTORY_PICTURES) returns.
AFAIK, that will not give you a directory named `SpCars_album/`.
I just cant understand what raises the error because everything seems to fit.
The file you supplied is not one that can be served by the `FileProvider` from your defined roots.
UPDATE
I forgot that this is tied to a documentation bug on `FileProvider`. `FileProvider` and `<external-path>` does NOT serve files from `getExternalFilesDir()`, but instead from `Environment.getExternalStorageDirectory()`. I created a `StreamProvider` subclass that offers support for `getExternalFilesDir()`.
If you use my `StreamProvider`, replacing your `<external-path>` with `<external-files-path name="myexternalimages" path="Pictures/SpCars_album/" />`, you should have better luck.
Problem
I have been trying to follow the Android tutorial on sharing files. I set up the `FileProvider` like this: On the main manifest xml: ``` <provider android:name="android.support.v4.content.FileProvider" android:authorities="com.example.mysecondapp.fileprovider" android:exported="false" android:grantUriPermissions="true" > <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/filepaths" /> </provider> ``` the res/xml/filpaths.xml file: ``` <paths xmlns:android="http://schemas.android.com/apk/res/android"> <external-path name="myexternalimages" path="SpCars_album/" /> </paths> ``` And in my code I am trying the following: ``` File requestFile = new File(mImageFilenames[position]); try { fileUri = FileProvider.getUriForFile( SeventhActivity.this, "com.example.mysecondapp.fileprovider", requestFile); } catch (IllegalArgumentException e) { Log.e("File Selector", "The selected file can't be shared: " + mImageFilenames[position]); } ``` The requestFile is instantiated with a proper working path for a file. The path of that file begins exactly with what `getExternalFilesDir(Environment.DIRECTORY_PICTURES)` returns. I just cant understand what raises the error because everything seems to fit. Thanks in advance.
