Android File Provider Illegal Argument Exception

Question

I am using file provider to save photo to a given destination. I get:

java.lang.IllegalArgumentException: Missing android.support.FILE_PROVIDER_PATHS meta-data while trying to open activity to capture image from camera.

My manifest.xml file:

<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.example"
android:exported="false"
android:grantUriPermissions="true">
    <meta-data
    android:name="android.support.FILE_PROVIDER_PATHS"
    android:resource="@xml/paths" />
</provider>

My paths.xml file:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="content" path="Android/data/com.my_package_name/files/" />
</paths>

and Java code:

File externalFilesDirectory = this.getExternalFilesDir(null);
File imageFile = File.createTempFile(
        imageFileName,
        ".jpg",
        externalFilesDirectory
);
Uri photoURI = FileProvider.getUriForFile(this, "com.example", imageFile);

Last line gives the exception. What am I missing here? I've followed tutorial from official Android development site (https://developer.android.com/training/camera/photobasics.html)

Can you add the tutorial link. – Imran Ali Aug 16 '16 at 14:59 — Imran Ali, Aug 16 '16 at 14:59
`com.example` should be `"com.example"`. Does that fix it? – Imran Ali Aug 16 '16 at 15:08 — Imran Ali, Aug 16 '16 at 15:08
Nope, just an error in copying – Michał Aug 16 '16 at 15:15 — Michał, Aug 16 '16 at 15:15

I found the solution. The problem was that my authority name didn't end with ".fileprovider". Fixed.

Can you provide link to any document to require FileProvider authority name must end with ".fileprovider"? – anticafe May 24 '17 at 03:37

This might have been a bug in android that they later fixed, coz I am using an Authority without the `.fileprovider` extension. It works fine. – Henry Sep 11 '17 at 14:46

sometimes ordering matters. I have used .provider in my authority name & its accepted, only the fact that if I am having more than 1 provider, then file provider should be declared first. – Ashish John Oct 25 '17 at 12:02

Even when you have authorities properly set up to the appId and there is the FileProvider setup , you should ideally delete the caches , i.e. Delete .gradle and .idea folders or probably Invalidate the caches and restart which enables you to redownload the gradle dependencies again and then it worked for me :) Hope this might help someone
