This program is written in Delphi/Pascal, but I don't think this has much to do with language.
I'm having an issue launching a PDF from my application, which I assume is related to an error I see with adb logcat
04-23 19:45:23.315 1153 7393 W UriGrantsManagerService: No content provider found for permission check: content://com.embarcadero.XXXXX/pdfs/report.pdf
04-23 19:45:23.315 1153 7393 I ActivityTaskManager: START u0 {act=android.intent.action.VIEW dat=content://com.embarcadero.XXXXX/pdfs/report.pdf typ=application/pdf flg=0x1 cmp=com.google.android.apps.docs/com.google.android.apps.viewer.PdfViewerActivity} from uid 10630
Through a file explorer app, I have verified that the PDF is downloaded to and viewable from
/Android/data/com.embarcadero.XXXXX/files/Download/report.pdf
But for some reason when I launch the intent through my own app, it is not able to open.
I have setup my Manifest as follows:
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="com.embarcadero.XXXXX.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths"/>
</provider>
And I have defined provider_paths.xml as
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path name="pdfs" path="./files/Download"/>
</paths>
