Android Question several basic (noobish) questions

[Himred]

It's me again asking for simple questions I did not found an answer on the huge knowledge base of previous posts.

1: When I use a tablet to go to my app google play page it says "application designed for phones".
This is not the case as it is also designed for tablets.
What should I add to be tagged as designed for tablets too (in the manifest ? in the first # of the code ?)


2: On the google play android console we have counters for crashes, I saw one crash stated as Out of memory, the debug show it is related to bitmaps.
Of course it never happened here (would be too easy to debug, universe like complex situations).
I only load few (<10) small (<10K) bitmaps on my app, so i was surprised by that out of memory error.
About bitmaps should I initialize them only on first time or each time Activity_Create is executed, actually i initialize them on Activity_Create whatever firstime is true or false, is it the right way ?
If you have any advice to help me track down such events, feel free to help.


Thanks for reading and any help you could provide.

1. Note that your app is supported by tablets even if you see this message. See this tutorial: Google Play: "Designed for tablet screens"

2. The image file size doesn't really matter. What matters is the image dimensions. You should use LoadBitmapSample if the dimensions are larger than the target view.

Are you using Canvas?

Image are very small (256x256) and they are just as background of labels (but a lot of labels) i can have up to 120 labels with a background image.

Can you post the full error message from Google Play?

The error might not be related to bitmaps at all. It does seem like a memory problem. However this stack trace happened when it tried to show the "standard error msgbox". This means that the process was already very very low on memory when an error has occurred.

hmmmm
Thanks Erel.

One question:

if i do mybitmap.initialize(dir,"toto.png")
and later in code I do mybitmap.initialize(dir,"toto2.png") because user changed theme
what happen to first bitmap ? it stays in memory or it is deleted ?

 

[Erel]

If the bitmap object is not referenced by any other object then its will be released (when the garbage collector runs).
