Android Question Bitmap.Initializemutable does not work

[grafsoft]

Hi,

my code works on most devices, but there is one where it does not work.

This is my code

   Bitmap1.Initialize(Main.outdir,Main.thepic)
   Log (wi) 
   Log (he) 
   Bitmap2.InitializeMutable(wi,he)
   Log ("Bitmap2.InitializeMutable(wi,he)")
   If Bitmap2.IsInitialized=False Then Log ("No success")

This is my log

4160

2339

Bitmap2.InitializeMutable(wi,he)

No success

java.lang.RuntimeException: Object should first be initialized (Bitmap).

Thank you

What are the values of wi and hi? Maybe there isn't enough memory available?

It is worth checking the unfiltered logs.

 

[sorex]

that would require almost 38Mb

 

[Erel]

I missed the values in the logs. As @sorex wrote the bitmap size is too large.

 

[grafsoft]

that would require almost 38Mb

The values are 4160 and 2339.

How can I calculate the memory I need for this?

How can I find the free memory on a phone?

Thank you

Peter

Approximately: Width * Height * 4 (bytes)

The process memory limit changes between different devices. You can ask the OS to give you more memory by setting the LargeHeap attribute in the manifest editor.

Why do you need such a large bitmap?

 

[grafsoft]

To put a photo on it and then draw on it. This phone has a camera with a very high resolution.

You will need to use a smaller bitmap. I guess that you are showing the full image on the activity so there is no reason to keep the full image size.
