        mIntent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME,
                file.getAbsolutePath());

尝试这个，

File pdfFile = new File(Environment

  .getExternalStorageDirectory(), "your.pdf");


try {

 if (pdfFile.exists()) {

  Uri path = Uri.fromFile(pdfFile);

  Intent objIntent = new Intent(Intent.ACTION_VIEW);

  objIntent.setDataAndType(path, "application/pdf");

  objIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

  startActivity(objIntent);

 } else {

  Toast.makeText(MainActivity.this, "File NotFound",

    Toast.LENGTH_SHORT).show();

 }

} catch (ActivityNotFoundException e) {

 Toast.makeText(MainActivity.this,

   "No Viewer Application Found", Toast.LENGTH_SHORT)

  .show();

} catch (Exception e) {

 e.printStackTrace();

}
