Question

I have a file path: file:///storage/emulated/0/Android/data/rocks.vd.*****.develop/files/1Q 2017 financial results.pdf

this is code:

Intent intent = new Intent(Intent.ACTION_VIEW);
    try {
        String newFilePath = filePath.replaceAll("%20", " ");
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {
            intent.setDataAndType(Uri.parse(newFilePath), "application/pdf");
        } else {
            Uri uri = Uri.parse(newFilePath);
            File file = new File(uri.getPath());
            if (file.exists()){
                uri = FileProvider.getUriForFile(context, context.getPackageName() + ".provider", file);
                intent.setDataAndType(uri, "application/pdf");
                intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
            }
        }

        intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        context.startActivity(intent);

My uri = content://rocks.vd.*****.develop.provider/files/Android/data/rocks.vd.*****.develop/files/1Q%202017%20financial%20results.pdf

Pdf reader is opening with Unexpected error. Whats wrong?

Answer 1

intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Here you are wiping out all your existing flags, notably your FLAG_GRANT_READ_URI_PERMISSION. As a result, the activity that you start will not have access to your content.

Switch from setFlags() to addFlags().
