    <p>I am having difficulties understanding the right way to split initialization and maintenance of application state between Activity, GLSurfaceView and Renderer. Let's say I have a game with complex objects, complex state and want to preserve the state and load it on each onResume. My initialization goes like this:</p> <pre><code>public class MyActivity extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); gamescreenView = (GLGameScreenSurface) findViewById(R.id.GLGamescreenView); ... if (savedInstanceState == null) { Game.init(); resuming = false; } else { gamedata = (GameData) savedInstanceState.getSerializable("gamedata"); resuming = true; } renderer = new MyRenderer(this, gamedata, gamescreenView, handle, resuming); gamescreenView.setRenderer(renderer); } @Override public void onPause(){ super.onPause(); gamescreenView.onPause(); gamedata = renderer.gamedata; } @Override public void onResume(){ super.onResume(); gamescreenView.onResume(); renderer.gamedata= gamedata; } @Override public void onSaveInstanceState(Bundle savedInstanceState) { super.onSaveInstanceState(savedInstanceState); savedInstanceState.putSerializable("gamedata", renderer.gamedata); } @Override public void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); gamedata = (UniverseHolder) savedInstanceState.getSerializable("gamedata"); } </code></pre> <p>here is my Renderer:</p> <pre><code>public class MyRenderer implements GLSurfaceView.Renderer { public WideOpenRenderer(Context context, UniverseHolder universe, GLGameScreenSurface gamescreenView, Handler handler, boolean resuming) { this.context = context; this.handler = handler; parent = gamescreenView; this.gamedata = gamedata; this.resuming = resuming; } public void onSurfaceCreated(GL10 unused, EGLConfig config) { GLES20.glClearColor(0.0f, 0.0f, 0.0f, 1.0f); Log.d("mydebug", "" + resuming); gamedata.init(); } ... </code></pre> <p>But it does not work this way and resuming is always false according to the log.</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
