Zur Zeit habe ich ein pdfurl, und ich möchte einfach die absicht verwenden, um es zu öffnen, es funktioniert jedoch nicht, wenn ich das steckeurl imintent

Mein Code ist so, er wirft immerActivityNotFoundException Error

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(law.url), "application/pdf");

try {
    startActivity(intent);
} catch (ActivityNotFoundException e){
    Utility.showErrorDialog(
        ctx,ctx.getResources().getString(R.string.sys_in, 
        ctx.getResources().getString(R.string.err_no_pdf_reader), 
        ctx.getResources().getString(R.string.close));
}

Ich habe auch den goolge doc-Ansatz ausprobiert, aber mein Client lehnt dies ab, sodass ich diese Methode nicht verwende

Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.parse("http://docs.google.com/viewer?url=" 
+ publish.get(Integer.parseInt((String) view.getTag())).pdfURL), "text/html");  
ctx.startActivity(intent);

Danke für die Hilfe
