I'm trying to open a pdf after creating it via an intent. The file exists and is readable but save inside the apps directory.
Currently the file is saved in the following manner
OutputStream out;
try {
//TODO: expose through a content provider
out = mContext.openFileOutput(outputFileName, Context.MODE_WORLD_READABLE);
document.writeTo(out);
out.close();
and the file is sent to an intent with the following code
final Intent viewIntent = new Intent();
viewIntent.setAction(Intent.ACTION_VIEW);
viewIntent.setDataAndType(Uri.fromFile(file), "application/pdf");
mActivity.startActivity(viewIntent);
The app trying to open it is the google drive viewer and I see in the Android monitor
E/PdfViewerActivity: fetchFile:file: java.io.FileNotFoundException: file does not exist
This previously worked and I don't think I've changed anything related to this code however I have updated my tooling. I've tried changing the buildToolsVersion in the build.gradle back to what it was before as well as the support libraries 'com.android.support:appcompat-v7:22.+' and 'com.android.support:design:22.+' instead of version 24.2.1
I've tried using the debugger to set the file to be readable just before sending the intent but that did not work.
Thanks

I found the answer starting with the Android 7 Behavior Changes documentation. Sharing files is no longer allowable when setting MODE_WORLD_READABLE even though the documentation doesn't mention any of this
I followed the documentation on sharing files to fix the issue but the sample code in the documentation was more complicated than what I needed. I still had to add the file provider to the AndroidManifest.xml as well as create the fileprovider.xml.
The resulting code is now
final Intent viewIntent = new Intent();
viewIntent.setAction(Intent.ACTION_VIEW);
Uri fileUri = FileProvider.getUriForFile(mActivity, "my.authority.fileprovider", file);
viewIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
viewIntent.setDataAndType(fileUri, "application/pdf");
