Out of memory error on android emulator, but not on device

Question

On the Android Emulator, when I exit my app and run it again immediately, I get

OutOfMemoryError: bitmap size exceeds VM budget.

But on the device itself, this does not happen. Why?

I think you are using static Bitmap array, which you not assigning to null after leaving activity. set that to null on closing activity. — Balaji Khadake, Sep 15 '11 at 08:21

On a emulator the default max heap size is around 13MB.

On a device, it depends of the phone and of the android version. On my Motorola Droid, the max heap size is around 21-22MB and on my HTC Desire it's around 32MB.

That's why you have a crash on the emulator and not on your device.

If you want to monitor the heap size of your application you can call a similar method:

protected void displayMemoryUsage(String message) {
    int usedKBytes = (int) (Debug.getNativeHeapAllocatedSize() / 1024L);
    String usedMegsString = String.format("%s - usedMemory = Memory Used: %d KB", message, usedKBytes);
    Log.d(TAG, usedMegsString);
}

found out a big problem in my program, it uses way too much memory. I load a bitmap(478 KB) but it takes ~5000 KB to load it – piojo Sep 15 '11 at 09:19
It seems a bit too much memory for a single image. What is the resolution of this image and it's format? If you do not need the full resolution image in your app, did you consider reducing it's resolution or adding a inSampleSize in your BitmapFactory? – ol_v_er Sep 15 '11 at 11:52

Increase the AVD RAM and the max VM application heap size in VM options.

To do that, go to

Window-->AVD Manager-->Virtual Devices-->Edit.

Some sample max heap sizes: G1 = 16 Mb Droid = 24 Mb Nexus One = 32 Mb Xoom = 48 Mb GalaxyTab = 64 Mb. – Avram Score Sep 15 '11 at 21:36

Probably it is because you're device has more memory than your emulator. This SO question shows you how to increase the size on your emulator.

Additionally you could increase the Java VM Heap size.
