Android setdrawable from another class

Here's my code. I am trying to set background of a linear layout. But this xml (rowback) is not my main activity content, so gives errors. how can I set some XML from the class which doesn't have that XML in its content?
setContentView(R.layout.activity_quick_search_products);
...
rowb = (LinearLayout)findViewById(R.id.rowback);
...
final Drawable d = getResources().getDrawable(R.drawable.denemebut3);
d.setAlpha(100);
rowb.setBackgroundDrawable(d);

If R.id.rowback doesn't belong to your main activity xml resource, then you should inflate that resource manually using:
LinearLayout rowb = (LinearLayout) getLayoutInflater().inflate(XML file that contains R.id.rowback, null);
then you can safely do
rowb.setBackgroundDrawable(d);
As an extra, if you have nested elements in rowback then you can invoke:
rowb.findViewById(R.id.Something) safely.
Or if your class is not exteding from any Activity, you can always receive a Context object in its constructor, and then use
LayoutInflater.from(context)
to get a LayoutInflater object so you can inflate any XML resource you need that is not actually in your main content.
Hope this clarifies...

I am developing an app for all android devices. It is working good on all device and I tested it on Samsung Galaxy S1, Galaxy Nexus, Motorola Xoom, HTC One and also on Amazon Kindle Fire.
It runs perfectly on all devices but when i tried using it on Nexus 7, it crashes and in log it says Out of Memory Error. I tried using System.gc(); in Activity#onPause() method but in vain. There are alternative drawables and layouts exist in app.
Please help me to resolve this issue. This issue is only specific to Nexus 7.
Below is stacktrace:

Ya i had faced this issue too but not found a valid solution but you can try using android:largeHeap="true" in manifest at application level

I tried to run my app, but it is crashing before reaching the onCreate() method. I'm new to android and eclipse, so i do not even know where to start searching for the error.

From what i can say from the logcat (the code would help to make this even clearer), you wrote something in the constructor.
This is bad practice unless you exactly know what you are doing(but i think yours is just a first-timer error ;) ).
You should do everything to initialize your app in the overridden onCreate method.
Try not to create any constructor, and move everything in the onCreate method.
And remember, activities doesn't have a main function, and you can't pass arguments to them(there are special classes to pass data between activities)
EDIT:
now that i look better at your logcat, i can tell you even more.
You are using sharedPreferences in the constructor, but when the constructor is called, the activity doesn't exist yet, so it doesn't have any prederenceManager. This is why you get a null pointer. As i said, moving everything in the onCreate method will solve your problem

Sorry the application Sudoku has stopped unexpectly. Please try again

Help!
I’m having problems with my Sudoku application. I plugged in all the code to have my application remember the current position. Now when I run the application and I try to either start a new game or continue my Sudoku application says:
Sorry the application Sudoku (process org.example.sudoku) has stopped unexpectedly. Please try again.
It hasn’t done this in the past yet and I’m confused on where to go from here. I took a look at the logcat but I’m not sure what I should look for and how to fix it. Here is the logcat below

You need to look at line 104 of Game.java as it seems it may be the cause of a NullPointerException

Your error of interest is:
12-05 14:48:15.295: ERROR/AndroidRuntime(304): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{org.example.sudoku/org.example.sudoku.Game}: java.lang.NullPointerException
Usual error - your intent is not in the Manifest.xml

BadTokenException

You cannot display an application window/dialog through a Context that is not an Activity. Check please that every time you start a dialog it gets correct Context.
