android.support.v4.content.FileProvider not found

Question

I am trying to upgrade a working old app to support Android API 26, and one of the thing I need to use is android.support.v4.content.FileProvider - but it was not found.

Answer 1

As of AndroidX (the repackaged Android Support Library), the path is androidx.core.content.FileProvider so the updated provider tag would be:

<provider
    android:name="androidx.core.content.FileProvider"
    android:authorities="${applicationId}.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Android Support Libraries are now in the androidx.* package hierarchy.

android.* is now reserved to the built-in Android System Libraries.

Answer 2

Create your class

import android.support.v4.content.FileProvider;

public class GenericFileProvider extends FileProvider {
}

Add this provider into your AndroidManifest.xml under application tag:

<provider
      android:name=".utilities.GenericFileProvider"
      android:authorities="${applicationId}.utilities.GenericFileProvider"
      android:exported="false"
      android:grantUriPermissions="true">
         <meta-data
             android:name="android.support.FILE_PROVIDER_PATHS"
             android:resource="@xml/provider_paths" />
</provider>
