Passing android Bitmap Data within activity using Intent in Android

Question

I hava a Bitmap variable named bmp in Activity1 , and I want to send the bitmap to Activity2

Following is the code I use to pass it with the intent.

Answer 1

Kotlin Code for send Bitmap to another activity by intent:

1- in First Activity :

          val i = Intent(this@Act1, Act2::class.java)
           var bStream  =  ByteArrayOutputStream()
            bitmap.compress(Bitmap.CompressFormat.PNG, 50, bStream)
            val byteArray = bStream.toByteArray()
            i.putExtra("image", byteArray )
            startActivity(i)

2- In Activity two (Read the bitmap image) :

 var bitmap : Bitmap? =null
    if (intent.hasExtra("image")){
      //convert to bitmap          
        val byteArray = intent.getByteArrayExtra("image")
        bitmap = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.size)
    }

3- if you need to set it as background for a view, like ConstraintLayout or... :

 if (bitmap != null) {
     //Convert bitmap to BitmapDrawable
     var bitmapDrawable = BitmapDrawable( resources , bitmap)
      root_constraintLayout.backgroundDrawable = bitmapDrawable
   }
