FileProvider error
If someone is having hard time as me with support.v4.content.FileProvider you can replace it with this.
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="com.camera.app.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths">
</meta-data>
</provider>
I also forgot to put <provider>
within <application>
; I mistakenly put them on the same level which I have since fixed.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="zm.mytestapplication">
<application
...
android:theme="@style/AppTheme">
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="zm.mytestapplication.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"></meta-data>
</provider>
</application>
</manifest>
file_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="my_images" path="Pictures/zm/" />
</paths>
I finally got it to work!
Remember to put the provider tag INSIDE the application tag in the manifest file - that was my mistake (my provider tag was OUTSIDE of the application tag), and the reason you get this error, which basically says it cannot find the definition of the Provider.
Also make sure you have the correct paths in the .xml file. Here is my version:
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="my_images"
path="Android/data/org.projects.cameraapp/files/Pictures" />
</paths>
Of course you have to change the path for your own application.
My actual Provider then looks like this:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="org.projects.cameraapp.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/filepaths" />
</provider>
Again, you'll need to change the authorities value in your own application.
