Failed binder transaction when putting an bitmap dynamically in a widget

Question

Can anybody tell me the reason for failed binder transaction error  I can see this error message in logcat  I am getting this error while trying to put an bitmap dynamically in a widget

User · Answer

The Binder transaction buffer has a limited fixed size, currently 1Mb, which is shared by all transactions in progress for the process. Consequently this exception can be thrown when there are many transactions in progress even when most of the individual transactions are of moderate size.

See my answer in this thread   intent putExtra  Some string  very large obj for binder buffer    You are exceeding the binder transaction buffer by transferring large element s  from one activity to another activity

You can compress the bitmap as an byte s array and then uncompress it in another activity  like this   Compress            ByteArrayOutputStream stream   new ByteArrayOutputStream            bmp compress Bitmap CompressFormat PNG  100  stream           byte   bytes   stream toByteArray             setresult putExtra  BMP  bytes     Uncompress            byte   bytes   data getByteArrayExtra  BMP            Bitmap bmp   BitmapFactory decodeByteArray bytes  0  bytes length

I have solved this issue by storing images on internal storage and then using  setImageURI   rather than  setBitmap

User · Answer

The right approach is to use setImageViewUri    slower  or the setImageViewBitmap   and recreating RemoteViews every time you update the notification

User · Answer

This is caused because all the changes to the RemoteViews are serialised  e g  setInt and setImageViewBitmap    The bitmaps are also serialised into an internal bundle  Unfortunately this bundle has a very small size limit   You can solve it by scaling down the image size this way    public static Bitmap scaleDownBitmap Bitmap photo  int newHeight  Context context      final float densityMultiplier   context getResources   getDisplayMetrics   density            int h   int   newHeight densityMultiplier    int w   int   h   photo getWidth     double  photo getHeight        photo Bitmap createScaledBitmap photo  w  h  true     return photo       Choose newHeight to be small enough   100 for every square it should take on the screen  and use it for your widget  and your problem will be solved
