Body
I am trying to pass an intent with data from Activity A to FragmentActivity B to Fragment B. A button from Activity A starts FragmentActivity B. The "year" string sets a filter with which I query a mysql database on a remote server. The code below works but only half the time. I have no idea what causes it to filter just some times and at other times it just returns the whole table unfiltered. I am guessing it has to be related to the intent I am using in the fragment because the filter worked without issue in the version of the app without the fragment. It also seems inefficient the way I am sending the intent from Activity A to FragmentActivity B to Fragment B. How can I fix this problem? Activity A: <pre><code>Button button1 = (Button)findViewById(R.id.button1); button1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(); intent.setClass(FindMovie.this, ShowMovies.class); intent.putExtra("year", year1); startActivity(intent); } }); </code></pre> FragmentActivity B: <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_show_movies); if (getSupportFragmentManager().findFragmentByTag(TAG) == null) { final FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.add(android.R.id.content, new ImageGridFragment(), TAG); ft.commit(); } Intent i = getIntent(); year = i.getStringExtra("year"); //resend through another intent to the fragment B Intent intent = new Intent(getApplicationContext(), ImageGridFragment.class); intent.putExtra("year", year); } </code></pre> Fragment B: <pre><code>@Override public View onCreateView( LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { final View v = inflater.inflate(R.layout.image_grid_fragment, container, false); Bundle extras = getActivity().getIntent().getExtras(); year = extras.getString("year"); return v; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
