how do you pass images (bitmaps) between android activities using bundles?

Question

Suppose I have an activity to select an image from the gallery, and retrieve it as a BitMap, just like the example: here

Now, I want to pass this BitMap to be used i

Answer 1

I had to rescale the bitmap a bit to not exceed the 1mb limit of the transaction binder. You can adapt the 400 the your screen or make it dinamic it's just meant to be an example. It works fine and the quality is nice. Its also a lot faster then saving the image and loading it after but you have the size limitation.

public void loadNextActivity(){
    Intent confirmBMP = new Intent(this,ConfirmBMPActivity.class);

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    Bitmap bmp = returnScaledBMP();
    bmp.compress(Bitmap.CompressFormat.JPEG, 100, stream);

    confirmBMP.putExtra("Bitmap",bmp);
    startActivity(confirmBMP);
    finish();

}
public Bitmap returnScaledBMP(){
    Bitmap bmp=null;
    bmp = tempBitmap;
    bmp = createScaledBitmapKeepingAspectRatio(bmp,400);
    return bmp;

}

After you recover the bmp in your nextActivity with the following code:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_confirmBMP);
    Intent intent = getIntent();
    Bitmap bitmap = (Bitmap) intent.getParcelableExtra("Bitmap");

}

I hope my answer was somehow helpfull. Greetings
