Does that help "Beginning in Android 6.0 (API level 23), users grant permissions to apps while the app is running, not when they install the app. This approach streamlines the app install process, since the user does not need to grant permissions when they install or update the app."
change it to
code :
private void requestPermission(String permission){
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M){
        if (ContextCompat.checkSelfPermission(BookListActivity.this, 
                Manifest.permission.READ_EXTERNAL_STORAGE)
                        != PackageManager.PERMISSION_GRANTED) {

                        ActivityCompat.requestPermissions(BookListActivity.this,
                                new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
                                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        }
    }
}

it should still fix some issue How to get a list of files, say ending with .avi , that are on the users SD card? . , Use FileFilter for scanning the .avi files from sdcard. like:
code :
 //Check media mounted or not
 if(Environment.MEDIA_MOUNTED.equals(Environment.getExternalStorageState()))
 {
 File sdCardDir=new File("/sdcard");
 File sdCardDir=Environment.getExternalStorageDirectory();
 ArrayList<File>files=getFiles(file);

 private ArrayList<File> getFiles(Filefile){
 File files[]=sdCardDir.listFiles(filter);

 for(File f:files){
     if(f.isDirectory()&&f.canRead()){
     getFiles(f);
     }else if(f.isFile()){
     videlList.add(f);
 }
 } 
 //USE FileFilter 
 FileFilter filter=new FileFilter(){
 @Override
 public boolean accept(File f){
 return f.isDirectory()||f.getName().matches("^.*?//.(avi)$");
 }  
 }

I think the issue was by ths following , I assume you want to write an app to do this for you then? What you'll need to do is either set the folder to search or recursively search through the file system on your nexus and check for PDF files. You'll then need to use a library like PDFbox to search the text. There's a decent tutorial here
Please note that this will be fairly slow but it is a straightforward solution.
