Try this,

Stringpath= Environment.getExternalStorageDirectory().toString();
Filedir=newFile(path,"/MeaVita");
 if (!dir.isDirectory()) {

It seems you are access empty/null File[] . you may modify the code structure like,

Stringpath= Environment.getExternalStorageDirectory().toString();
 Filedir=newFile(path,"/MeaVita");

 photosLayout.setOnClickListener(newView.OnClickListener() {
    @OverridepublicvoidonClick(View v) {

        checkFilePermissions();
          if (!dir.isDirectory()) {
             dir.mkdirs();
          }

        Filefile1=newFile(Environment.getExternalStorageDirectory().getPath() + "/MeaVita");
        File[] listFile = file1.listFiles();

          if (listFile.length == 0) {
                Toast.makeText(MainActivity.this, "The folder is empty.", Toast.LENGTH_SHORT).show();
            } else {

                newMainActivity.SingleMediaScanner(MainActivity.this, listFile[0]);
            }

    }
});

 if (checkSelfPermission(android.Manifest.permission.WRITE_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_GRANTED) {
     if (!dir.isDirectory()) {
         dir.mkdirs();
     }


     if (listFile.length == 0) {
                Toast.makeText(MainActivity.this, "The folder is empty.",Toast.LENGTH_SHORT).show();
            } else {
                newMainActivity.SingleMediaScanner(MainActivity.this, listFile[0]);
            }
    }
  } else {
        checkFilePermissions();
