Sharing Files with Android Java 27.06.24

# Declare the shared folder
```xml
<?xml version="1.0" encoding="utf-8"?>
<paths>
    <cache-path  name="shared_images"  path="images"/>
    <external-files-path name="my_images" path="/Pictures/myGeo" />
    <external-path name="my_images" path="/Pictures/myGeo" />
</paths>
```

# Java Code to Share
```java

//Set up an Image via Bitmap
Bitmap bmp =  Bitmap.createBitmap(500, 500 , Bitmap.Config.ARGB_8888);
bmp.eraseColor(Color.RED);
Canvas canvas = new Canvas(bmp);
Paint paint = new Paint();
paint.setColor(Color.WHITE);
paint.setTextSize(100);
canvas.drawText("Hello World", 5, 50, paint);
File file = new File(path, "test.jpg");

//Save the Image to the shared folder
try (FileOutputStream out = new FileOutputStream(filename)) {
bmp.compress(Bitmap.CompressFormat.PNG, 100, out); // bmp is your Bitmap instance
// PNG is a lossless format, the compression factor (100) is ignored
} catch (IOException e) {
e.printStackTrace();
}

Intent i = new Intent(Intent.ACTION_SEND); //Create Intent
i.setType("image/*"); //Set the Sending type

Uri uri = FileProvider.getUriForFile(c, "org.calantas.mygeo", file); //Declare the file to the Fileprovider

//Make the Authoriy to send
List<ResolveInfo> resInfoList = context.getPackageManager().queryIntentActivities(i, PackageManager.MATCH_DEFAULT_ONLY);

for (ResolveInfo resolveInfo : resInfoList) {
String packageName = resolveInfo.activityInfo.packageName;
context.grantUriPermission(packageName, uri, Intent.FLAG_GRANT_WRITE_URI_PERMISSION | Intent.FLAG_GRANT_READ_URI_PERMISSION);
}

i.putExtra(Intent.EXTRA_STREAM, uri); // Add the allowed uri to the intent

startActivity(Intent.createChooser(i, "Share Image"));  //start sharing

```
