推荐答案

尝试一下

private void openBook()
{
     File file = new File(mRealPath);
     Uri path = Uri.fromFile(file);
     Intent intent = new Intent(Intent.ACTION_VIEW);
     intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
     intent.setDataAndType(path, getString(R.string.application_type));
     try 
     {
         startActivity(intent);
     } 
     catch (ActivityNotFoundException e) 
     {
         Toast.makeText(FirstTab.this, 
         getString(R.string.no_application_found), 
         Toast.LENGTH_SHORT).show();
     }
}

文件中存在Adobe Reader的问题，因此我无法读取该值.我使用其他pdf阅读器阅读pdf文件.这样我就可以轻松读取该值.加上我的旧代码.

there was problem of adobe reader in file so i cant read that value. i used other pdf reader to read the pdf file. so i can easily read the value. with my old code.
