Google Maps API Android - Tile provider's tiles resolution

Google Maps API Android - Tile provider's tiles resolution - android

I'm using custom TileProviders in my Android app to display offline maps and OpenStreetMap maps. It works, but there is a problem with the tiles resolution, which is quite bad. The files have a size of 256x256, and setting the width/height of my TileProvider to 128 doesn't change anything.
Here is some piece of code :
public class GenericUrlTileProvider extends UrlTileProvider {
// ---------------------------------------------------------------------------------------
// Private attributes :
private String _baseUrl;
// ---------------------------------------------------------------------------------------
// ---------------------------------------------------------------------------------------
// Constructor :
public GenericUrlTileProvider(int width, int height, String url) {
super(width, height);
this._baseUrl = url;
}
#Override
public URL getTileUrl(int x, int y, int zoom) {
try {
return new URL(_baseUrl.replace("{z}", "" + zoom).replace("{x}", "" + x).replace("{y}", "" + y));
}
catch (MalformedURLException e) { e.printStackTrace(); }
return null;
}
// ---------------------------------------------------------------------------------------
}
Does anyone know how to fix this to support high resolution devices ?
Thanks

On #grub request, here is what I did for getting the 4 tiles of the next zoom level :
public Tile getTileFromNextZoomLevel(int x, int y, int zoom) {
final String topLeftTileUrl = _source.getUrlSchema().replace("{z}", "" + (zoom + 1)).replace("{x}", "" + (x * 2)).replace("{y}", "" + (y * 2));
final String topRightTileUrl = _source.getUrlSchema().replace("{z}", "" + (zoom + 1)).replace("{x}", "" + (x * 2 + 1)).replace("{y}", "" + (y * 2));
final String bottomLeftTileUrl = _source.getUrlSchema().replace("{z}", "" + (zoom + 1)).replace("{x}", "" + (x * 2)).replace("{y}", "" + (y * 2 + 1));
final String bottomRightTileUrl = _source.getUrlSchema().replace("{z}", "" + (zoom + 1)).replace("{x}", "" + (x * 2 + 1)).replace("{y}", "" + (y * 2 + 1));
final Bitmap[] tiles = new Bitmap[4];
Thread t1 = new Thread() {
#Override
public void run() { tiles[0] = Utils.getBitmapFromURL(topLeftTileUrl); }
};
t1.start();
Thread t2 = new Thread() {
#Override
public void run() { tiles[1] = Utils.getBitmapFromURL(topRightTileUrl); }
};
t2.start();
Thread t3 = new Thread() {
#Override
public void run() { tiles[2] = Utils.getBitmapFromURL(bottomLeftTileUrl); }
};
t3.start();
Thread t4 = new Thread() {
#Override
public void run() { tiles[3] = Utils.getBitmapFromURL(bottomRightTileUrl); }
};
t4.start();
try {
t1.join();
t2.join();
t3.join();
t4.join();
}
catch (InterruptedException e) { e.printStackTrace(); }
byte[] tile = Utils.mergeBitmaps(tiles, Bitmap.CompressFormat.JPEG); // PNG is a lot slower, use it only if you really need to
return tile == null ? TileProvider.NO_TILE : new Tile( (int) _source.getTileSize().getWidth(), (int) _source.getTileSize().getHeight(), tile);
}
And the Utils methods :
public static byte[] mergeBitmaps(Bitmap[] parts, Bitmap.CompressFormat format) {
// Check if all the bitmap are null (if so return null) :
boolean allNulls = true;
for (int i = 0; i < parts.length; i++) {
if(parts[i] != null) {
allNulls = false;
break;
}
}
if(allNulls) return null;
Bitmap tileBitmap = Bitmap.createBitmap(512, 512, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(tileBitmap);
Paint paint = new Paint();
for (int i = 0; i < parts.length; i++) {
if(parts[i] == null) {
parts[i] = Bitmap.createBitmap(256, 256, Bitmap.Config.ARGB_8888);
}
canvas.drawBitmap(parts[i], parts[i].getWidth() * (i % 2), parts[i].getHeight() * (i / 2), paint);
}
ByteArrayOutputStream stream = new ByteArrayOutputStream();
tileBitmap.compress(format, 100, stream);
byte[] bytes = stream.toByteArray();
return bytes;
}
public static Bitmap getBitmapFromURL(String urlString) {
try {
// Ensure the file exists :
if(Utils.getResponseCode(urlString) != 200) return null;
URL url = new URL(urlString);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.connect();
Bitmap bitmap = BitmapFactory.decodeStream(connection.getInputStream());
return bitmap;
}
catch (IOException e) { return null; }
}
You may have to adapt it for your needs. Please note that my app is still under development, and this code may need some tests / improvements.

CameraX Analysis / Camera onPreviewFrame

In CameraX Analysis, setTargetResolution(new Size(2560, 800), but in Analyzer imageProxy.getImage.getWidth=1280 and getHeight=400, and YUVToByte(imageProxy.getImage).length()=768000。In Camera, parameter.setPreviewSize(2560, 800) then byte[].length in onPreviewFrame is 3072000(equales 768000*(2560/1280)*(800/400))。How can I make CameraX Analyzer imageProxy.getImage.getWidth and getHeight = 2560 and 800, and YUVToByte(ImageProxy.getImage).length()=3072000? In CameraX onPreviewFrame(), res always = null, in Camera onPreviewFrame(), res can get currect value, what's the different between CameraX and Camera? And what should I do in CameraX?

CameraX Log
Camera Log

With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution() states that:
The maximum available resolution that could be selected for an
ImageAnalysis is limited to be under 1080p.
So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

Google Maps offline Mode on Android Application

Is there any posibility to show Google Maps if you are offline in your own App?
What about if I download an Area FROM Google Maps application for offline mode, could i visualize the map on the app that i develop if i don't have internet connection?
if not, What options do i have to make this possible? I just want to visualize the map when my app is offline...

I was looking for information, and My questions is, how can i download the tiles?

I was facing the same challenge, and none of the examples I found included a complete implementation of downloading the tiles, writing them to file and reading them from file.
This is my code, which reads the tile from file when it's available locally and downloads/saves the tile when not. This uses the OpenStreetMap.org tile server, but you could use any server you like by changing the URL.
private class OfflineTileProvider implements TileProvider {
private static final String TILES_DIR = "your_tiles_directory/";
private static final int TILE_WIDTH = 256;
private static final int TILE_HEIGHT = 256;
private static final int BUFFER_SIZE_FILE = 16384;
private static final int BUFFER_SIZE_NETWORK = 8192;
private ConnectivityManager connectivityManager;
#Override
public Tile getTile(int x, int y, int z) {
Log.d(TAG, "OfflineTileProvider.getTile(" + x + ", " + y + ", " + z + ")");
try {
byte[] data;
File file = new File(TILES_DIR + z, x + "_" + y + ".png");
if (file.exists()) {
data = readTile(new FileInputStream(file), BUFFER_SIZE_FILE);
} else {
if (connectivityManager == null) {
connectivityManager = (ConnectivityManager) getSystemService(
Context.CONNECTIVITY_SERVICE);
}
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
if (activeNetworkInfo == null || !activeNetworkInfo.isConnected()) {
Log.w(TAG, "No network");
return NO_TILE;
}
Log.d(TAG, "Downloading tile");
data = readTile(new URL("https://a.tile.openstreetmap.org/" +
z + "/" + x + "/" + y + ".png").openStream(),
BUFFER_SIZE_NETWORK);
try (OutputStream out = new BufferedOutputStream(new FileOutputStream(file))) {
out.write(data);
}
}
return new Tile(TILE_WIDTH, TILE_HEIGHT, data);
} catch (Exception ex) {
Log.e(TAG, "Error loading tile", ex);
return NO_TILE;
}
}
private byte[] readTile(InputStream in, int bufferSize) throws IOException {
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
try {
int i;
byte[] data = new byte[bufferSize];
while ((i = in.read(data, 0, bufferSize)) != -1) {
buffer.write(data, 0, i);
}
buffer.flush();
return buffer.toByteArray();
} finally {
in.close();
buffer.close();
}
}
}
Replace "your_tiles_directory" with the path to the directory where you want to store your tiles.
To use the TileProvider:
map.setMapType(GoogleMap.MAP_TYPE_NONE);
offlineTileOverlay = map.addTileOverlay(new TileOverlayOptions()
.tileProvider(new OfflineTileProvider()));
Edit: You may want to set the max zoom level, the default is 21 but OpenStreetMap for example seems to have a maximum of 19.
map.setMaxZoomPreference(19);

You can download tile image from a tile server and cache on your app. Check some server on this link. Or you can build a tile as this demo, then download tile image from it.
Good luck

cant call set pixel on a recycled bitmap (debugging)

I've read some things about this problem named in the title, but I can't fix it in my code.
Only the Debugger shows me that 'cant call set pixel on a recycled bitmap' and closes the app.
So It's clear, to get an mutable Bitmap and manage the bitmap right. But where is my mistake?
I hope you can help me.

How to solve "No glyph for U+000A in font Helvetica-Bold" in pdfbox (android port)

I want to write some text into a pdf. I have the data in "icrResultTxt". I am also writing the data to text.txt file before trying to write to a pdf. When I try to write to the pdf I get "No glyph for U+000A in font Helvetica-Bold". How to solve it? I dont have any fondness for "Helvetica-Bold". I am willing to change to any font.

How to Use Android SeekBar For File Upload and Download using FTP?

I have an issue when I am trying to download a file from server using FTP. I need to display seek-bar status of downloading file and download speed of the Internet. I am able to display seek-bar status and speed of the Internet for HTTP, but for FTP I am not able to perform that same task. In the attached image below I need to display seek-bar and network speed for FTP and HTTP. Below is the source code I used for HTTP and FTP. I don't know where I missed it?
HTTP Code:
