OutOfMemoryError problems - android

my app (memory game) is using various images. In my /drawable/ folder are about ~50 .png images with 252x252 size. My app has some levels, for example 4x3, 4x6 etc. After 3-4 games (for example, I started from 2x2 to 4x6) - my app is crashing (Unfortunately, your app has stopped). In LogCat I have these errors:

As I said, I am using images from /drawable/ folder. To make for example 4x3 level, I am using GridLayout and ImageButtons. I have a method, which randomizes ImageButton's place and then I am putting the image to the ImageButton, like this:
button1.setImageResource(R.drawable.logo);
For resize my ImageButton I am using:
Display display = getWindowManager().getDefaultDisplay();
int screenwidth = display.getWidth();
int screenheight = display.getHeight();
button.setMaxHeight(screenwidth/3);
button.setMaxWidth(screenwidth/3);
So I do not really know, how to manage with my problem. Maybe should I use Bitmap instead of ImageResource?
Note:
1)Every level have own class, they are very similar to each other.
2)Every level class have 24 images. If the level is 4x3 I will get first random 6 pics.
3)Every activity are using finish(); method if the activity is closed/onBackPressed.
int[] img ={R.drawable.cherry90,R.drawable.apple90,R.drawable.applered90,R.drawable.apricot90,R.drawable.banana90,R.drawable.blueberry90,
R.drawable.coconut90,R.drawable.gooseberry90,R.drawable.grape90,R.drawable.grapefruit90,R.drawable.kiwi90,R.drawable.lemon90,
R.drawable.lime90,R.drawable.mandarin90,R.drawable.mango90,R.drawable.melon,R.drawable.papaya90,R.drawable.peach90,
R.drawable.pears90,R.drawable.pineapple,R.drawable.plums90,R.drawable.pomegranate90,R.drawable.raspberry90,R.drawable.strawberry90};
I hope you will understand what I wanted to say. I were searching an answer to this problem, but did not find.

Basically it an error that indicates you have used excess of your ram memory allocations, there is nothing wrong in your code it just needs to be optimized.
Here are a few ways to do this:
Reduce the resolution of the images, you can still stretch them to the same size, but they wont show in as much detail.
Delete or re-use image variable space.
If you show the same image multiple times on the screen, like with most tiled maps. only create one variable where the image is stored.
Remember variables mean ram.

OpenCV on Android without OpenCV Manager

I know that my question was asked before.
But no solution is working for me.
For now I tried this solutions:
Solution 1
Solution 2
Solution 3
Solution 4
But no one of them worked for me.
My application project include a JNI part so I added all the mentioned line from THIS tutorial to the Android.mk file,
I comment this line :
if(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this, mLoaderCallback));
And added:
static {
if (!OpenCVLoader.initDebug()) {
// Handle initialization error
}
}
After public void onResume()
My application gets stuck and crushed when the OpenCV started.
This is the LogCat output:

Is it possible to work with OpenCV without the OpenCV manager(maybe include him in my app?)
Hope that someone can help here.
Thanks!

sure you can do that. You just need to have the specific OpenCV libraries packed in your APK. Have a look at my reply here.

Zxing CaptureActivity - crashing when launching activity

I am trying to integrate the QR reading capabilities of Zxing into a stand-alone app, and have been using this very helpful guide http://damianflannery.wordpress.com/2011/06/13/integrate-zxing-barcode-scanner-into-your-android-app-natively-using-eclipse/ along with these pointers Integrating the ZXing library directly into my Android application but after having built the library, and followed all steps to launch this activity on a button press, it still does not work. The app launches, but upon pressing the button, it crashes.

This is the output in logcat upon launching and then pressing the button. Am I missing something obvious here? This happens both when emulating and when running on a phone, btw.

we might have encountered the same error - In my case the solution was to separate the Ant targets to two calls (i.e. "ant myParameters myTarget1 myTarget2", and "ant myParameters debug delivery"). Hope this works for you, anyhow - Google need to add better support for their undocumented/faulty changes (and stackoverflow isn't the best place for questions that are not originated in stupidity, as the lifetime of a complex question isn't too long here).
If that doesn't work for you please elaborate your question.

I got this log from one of my users.
Any help on this would be very very helpful.
Regards,
Hari
I was finally able to replicate this issue through an emulator set up with 50MB memory and running on GSM network speed. The issue seems to be because of history being cleared and so the data being lost which the app was already having. Not sure how I can handle this though.. any help???

My guess is that:
You have an activity containing a TabHost (fine)
The contents of those tabs are activities (bad)
You are duplicating android:id values among some of the widgets in those activities (fatal)

I had this issue as well. I had two activities with widgets bearing the same IDs. In one file, this widget was a Button and in another file the widget was a Spinner. I changed the IDs so that the Spinner had a different ID than the Button and the problem went away. It seems that Android runs in to problems if you use the same ID on two different classes of widgets.

I had a similar problem
It was a result of two views [Button] having the same ID
it happend to me because
the eclipse xml editor showed one button but registered 2 of the same ID
I solved it by cutting the button saving and then pasting it and saving again.

see: http://code.google.com/p/android/issues/detail?id=3981

Sometimes this happens to me.
First Try This:
Delete the R.java file so that it regenerates.
Then try this:
I rename the id of the widget in the XML, and in the java.
Then delete the R.java file so it regenerates.
Run it to flush it out. Rename it back to the way it was, and its good to go.
