How to resolve a stack trace error

I have an Android app which has a minimum SDK at 2.1 and I am getting the following stack trace in the developer console:

The error doesn't happen in the newer devices with an updated Os.
Please help me resolve the issue or point me in the right direction.

Based on the java.lang.OutOfMemoryError: bitmap size exceeds VM budget message in the stack trace, it appears that one of the images in the view being opened in your onCreate() is too large.
Here's a page with some guidance. The main idea is to load a scaled down version of the image. I've found it best to also scale down (resolution, color-depth, etc.) the actual image file to maximize loading speed.

Monodroid Sliding Menu can't work at android 2.2

I used the SlidingMenu library in my application, according to https://github.com/xamarin/monodroid-samples/tree/master/SlidingMenu. I build and run application successfully on the android 4.0+, but I failed run application on the android 2.2, but I saw the android sliding menu https://github.com/jfeinstein10/SlidingMenu, it supports from android 2.1.
This is error code:

Forget me that I can't copy whole log, since the logs on the another machine can't connect to network. I analyse this log, it crashed at SldingMenuActivity onCreate method, it failed to create the listview for the behind view on the activity, but it can work on the android 4.0+, it's too strange.
The problem I found: my listview can't infalte on android 2.2, even my layout is so simple below
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ListView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/Home_MenuList"
/>
</LinearLayout>

If you take a look at the Caused by section in your Stack Trace it tells you:
Caused by: android.content.res.Resources$NotFoundException: File res/drawable/common_background.png from drawable resource ID #0x7f020081: .xml extension required
There is something wrong with that resource, are any of the ListViewItems using this Resource Drawable?

admob adview causes crash on android while rotating

I added the admob adview from xml like this;
<com.google.ads.AdView
android:id="#+id/adView"
android:layout_above="#id/footerContainer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
ads:adSize="BANNER"
ads:adUnitId="..."
ads:loadAdOnCreate="true"
ads:testDevices="TEST_EMULATOR" />
First; there seems to be no problem. But when i change the orientation of the screen a couple of times quickly; the app crashed. I have these errors;

I tried adding it programmatically as described here, but nothing changed... Any ideas?

For 1, what SDK version are you using, and what device are you running it on? This may be an emulator specific issue.
2 and 3 are likely due to not linking the AdMob library correctly. See Error inflating class com.google.ads.AdView.

What is the minimum VM Budget Size?

Short Version:
Is there a guaranteed minimum VM Budget Size (or at least a reasonable target)? I am exceeding it with an xml layout that is nothing but a linearlayout wrapping a single 30KB image.
Long version:
I'm getting the following error related to bitmap exceeding vm budget:

The line in the stacktrace that is my code is the following:
setContentView(R.layout.splash_page);
From here, Android attempts to inflate the resource splash_page.xml listed below:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/logo"/>
</LinearLayout>
The image "logo.png" is a 240x138px png sizing in at 30KB. It seems strange to me that this would exceed the budget whereas other pages where I have loaded 6 images totaling over 35KB total have not exceeded the budget. It seems like the only thing I can do is to shrink the image, but I have no idea how small to make it.

The minimum budget, so to speak, is 16MB, insofar as the smallest maximum heap size for an Android application is 16MB. You are not exceeding it with a single PNG file of the size you describe.
