FileProvider error “Failed to find configured root that contains /data/data/sawbodeployer.entm.illinois.edu …”

问题

I download video by android download manager and want to share this video, I follow through Manifas

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

and in file path.xml add this:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="video_folder" path="files/"/>
</paths>

and use this provider:

File file = new File(getActivity().getFilesDir() , videoPath);
                Uri uri = FileProvider.getUriForFile(getContext(), "my.domain", file);
                Intent intent = ShareCompat.IntentBuilder.from(getActivity())
                        .setType("video/3gp")
                        .setStream(uri)
                        .setChooserTitle("Choose bar")
                        .createChooserIntent()
                        .addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                startActivity(intent);

but I get error :

java.lang.IllegalArgumentException: Failed to find configured root that contains /data/data/sawbodeployer.entm.illinois.edu/files/AKA1_Fante_Ghana_HandWashing_Final.3gp

Where is its problem?

回答1:

Replace:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="video_folder" path="files/"/>
    <files-path name="name" path="path" />
</paths>

with:

<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <files-path name="video_folder" />
</paths>

path is used when there is some specific subdirectory under the root that you want to serve from. Your file is directly in getFilesDir(), and so you cannot use path.
