Android Question Bitmap to KeyValueStore

[Sergey_New]

I used kvs this:

Starter.kvs.PutBitmap(id,bmp)

Now I need to additionally save another string parameter in kvs.
How can I do it?

 

[teddybear]

What do you mean? save another string parameter with same id in kvs?

 

[MicroDrie]

See [B4X] KVS - KeyValueStore library

 

[Sergey_New]

What do you mean?

I need to pass and receive three parameters from kvs at once.

 

[MicroDrie]

I need to pass and receive three parameters from kvs at once.

Define a type with your thee parameters, fill the type with your thee parameters, write the thee parameters as type to and retrieve the three parameters in the type at once from the kvs.
Be awere that you can only have one time use the same type name definition for all B4XPages in B4XPage environment were the defined type name can access in all B4XPages separate from B4XPage where the type is defined.

 

[Sergey_New]

Define a type with your thee parameters

'    Type myTipe(id As String, bmp As Bitmap, s As String)

    Dim t As myTipe
    t.Initialize
    t.id="a"
    t.bmp=LoadBitmap(File.DirAssets, "arrow.png")
    t.s="x"
    Starter.kvs.Initialize(Starter.myFolder, "kvs.dat")
    Starter.kvs.Put("i", t)

There is an error on the last line of code. How to add myTipe correctly?

Spoiler: error

The object by kvs put can only be or contain primitive type. bitmap is non-primitive type, you only use putbitmap method.
if you want to use type to put, you need to convert bitmap to an array of byte.

Or convert it to base64 string Reduce image size before encoding, preferably without writing to disk.

Edit: link updated

 

[Sergey_New]

Reduce image size before encoding, preferably without writing to disk.

The link is not working, please fix it.

 

[MicroDrie]

Done as requested.

 

[Sergey_New]

teddybear, MicroDrie thanks!
Unfortunately too many transformations will take a significant amount of time when filling kvs with more than 200 images.
I will try other methods.

 

[MicroDrie]

Welli a new speed requirement, perhaps it works to store the image in blob and the two otter parameters in a sqlite database, and store the database in the kvs to prevent conversion.

Thank you, I'll keep that in mind.
