FileProvider Not Working with Camera

Please do not try to put exported="true" as pointed out by pskink, your app will crash the moment it loads. FileProvider is not meant to work in this state.

Tried intent.addFlags solution by CommonsWare. Not working. probably will only works with ACTION_SEND kind of intent.

I found the answer in this post. Apparently the manual granting way is the only solution. But we can always loop thru the list of candidate packages and grantPermission to all of them.

List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
    String packageName = resolveInfo.activityInfo.packageName;
    context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
