    <p>I modified somethings and it worked. Here is the code:</p> <p><strong>CustomMapTileProvider.java</strong></p> <pre><code>public class CustomMapTileProvider implements TileProvider { private static final int TILE_WIDTH = 256; private static final int TILE_HEIGHT = 256; private static final int BUFFER_SIZE = 16 * 1024; Override public Tile getTile(int x, int y, int zoom) { byte[] image = readTileImage(x, y, zoom); return image == null ? null : new Tile(TILE_WIDTH, TILE_HEIGHT, image); } private byte[] readTileImage(int x, int y, int zoom) { FileInputStream in = null; ByteArrayOutputStream buffer = null; try { in = new FileInputStream(getTileFile(x, y, zoom)); buffer = new ByteArrayOutputStream(); int nRead; byte[] data = new byte[BUFFER_SIZE]; while ((nRead = in .read(data, 0, BUFFER_SIZE)) != -1) { buffer.write(data, 0, nRead); } buffer.flush(); return buffer.toByteArray(); } catch (IOException e) { e.printStackTrace(); return null; } catch (OutOfMemoryError e) { e.printStackTrace(); return null; } finally { if ( in != null) try { in .close(); } catch (Exception ignored) {} if (buffer != null) try { buffer.close(); } catch (Exception ignored) {} } } private File getTileFile(int x, int y, int zoom) { File sdcard = Environment.getExternalStorageDirectory(); String tileFile = "/TILES_FOLDER/" + zoom + '/' + x + '/' + y + ".png"; File file = new File(sdcard, tileFile); return file; } } </code></pre> <p><strong>Add TileOverlay to your GoogleMap instance</strong></p> <pre><code>... map.setMapType(GoogleMap.MAP_TYPE_NONE); TileOverlayOptions tileOverlay = new TileOverlayOptions(); tileOverlay.tileProvider(new CustomMapTileProvider()); map.addTileOverlay(tileOverlay).setZIndex(0); ... </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.

SQuiL has stopped working due to an internal error.

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