I want to set a button style programatically. This means without needing to define an xml file. I thought that by setting the background resource of the button with the predefined style IDs I could do this.
The line of code that fails is:
b1.setBackgroundResource(android.R.style.Widget_DeviceDefault_Light_Button_Borderless_Small);
There is an exception that states
android.content.res.Resources$NotFoundException: Resource ID #0x1030179.
What am I doing wrong?
EDIT:
I have tried to this:
Button b = new Button(context,null,android.R.style.Widget_DeviceDefault_Button_Borderless);
This no longer throws an exception but no real style is applied to the button. There is just text and there is no different states for when its pressed.
EDIT2:
Adding the original stack trace as requested:

I had copy and edit the codes according to the answer from this post. But when I run the simulator, I got a runtime error saying "Unfortunately App Has Stopped". However, my logcat is showing a different error from the post.
I had tried clean project/rebuilt project/invalidate cache but still can't get the app to work.

Line 56 of my code is:
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
My machine have jdk 7, Android Studio 1.0.2, Android Support Library 21.0.3, Android Support Repository 11 and my AVD is running on API level 16 x86.
I am Building an Npuzzle App.
The current issue I face is bringing a drawable object into my Activity so that I can convert it to a bitmap for splitting. I have found and attempted to use this Approach:
Drawable hold = Puzzle.this.getResources().getDrawable(R.drawable.img1);
BitmapDrawable hold2 = (BitmapDrawable) hold;
Bitmap bitPhoto = hold2.getBitmap();
When I run my app I get a null pointer exception in the first line of code. Any suggestions on how to fix this problem? this is the logcat when i run the program:

Clean up your project and rebuild it to make sure the id of the drawable is the correct one.
Check if getResources() is actually returning something.
Edit: calling getResources() before super.onCreate() method returns, it causes NPE.
Why don't you just directly get the media as a bitmap?
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.img1);
Should be simpler than getting a drawable and casting it.
I have a very basic activity with an ImageView of android:id="#+id/imageViewTest"
and then in the OnCreate method calling:
ImageView imageView = (ImageView)findViewById(R.id.imageViewTest);
// Set the background color to white
imageView.setBackgroundColor(Color.WHITE);
this gives error:

But when I do a
ImageView imageView = new ImageView(this);
it works fine, Why?
PS: I am not able to add the layout code here, so sharing it in this doc: https://docs.google.com/document/d/1fbi3B_hAYUh_C2IwPfInvZ-BG2bgsa4pZoJKj8NBT9o/edit?usp=sharing
Your layout you've set with setContentView() doesn't have a view with id imageViewTest and findViewById() returns null, or you haven't called setContentView() at all.
I'm trying to use Log4j2 on Android, it fails with the following stacktrace. Android has no javax.naming support, and I don't really need this plugin in log4j2.
How can I disable Log4j2 JNDI plugin? (Or any other standard plugin)

You are using RC-2? Please raise this on the log4j2 Jira issue tracker so it will be fixed for the upcoming 2.0 release.
I am trying the same thing and encountered a similar problem with JNDI, i created a JIRA https://issues.apache.org/jira/browse/LOG4J2-703 with my code and the stacktrace i obtained.
