Hi everyone. Basically, I have a grid of ImageButtons, and if the user touches the right one, every image changes It worked fine on 2.x, but now I have a problem with 3.1, galaxy tabs 10.1 precisely. everytime I call setImageResource, (or setImageBitmap using BitmapFactory), the changing is awfully slow, and it provokes the logCat to display
"GC_FOR_ALLOC freed xK..." I tried to look into the heap, to use MAT, but I am not used to these tools and wasn't sure of what I was doing. here is the code I use to change every button's image for (int i = 0; i < n_lines; i++) { //for each line of the grid for (int j = 0; j < n_columns&& (i * n_columns) + j < objets.size(); j ++) { //and each column of the grid //we get the button, which Id has been changed to its index in the grid ImageButton ib = (ImageButton) findViewById( ( (i * n_columns) + j) ); //This line provokes a GC_FOR_ALLOC that takes around 23ms, only on a galaxy tab 10.1 (Android 3.1) ib.setImageResource(<ResID of the drawable>); } } The grid can be up to 6x6 (36), but even with a size of 2x2 (4), GC_FOR_ALLOC is called every time This piece of code takes about 40ms on a 2.x device (a HTC desire(2.3) and a galaxy tab 7(2.2) ) It takes over a second on a 3.1 device (four Galaxy tab 10.1) Am I doing something wrong? Are Resources or Drawables managed differently on Honeycomb? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
