Checkbox runtime error if before textview - android

I coded an app with several textview and checkbox.
Now I'm trying to add a new checkbox:
if I add it before a textview I get a runtime error,
if i add after it, there are no runtime error.
CODE:
In this way it does work
<TextView
android:id="#+id/tvInstructions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/impostazioni_19"
android:textColor="#FF0000"
android:textStyle="bold" />
<CheckBox
android:id="#+id/cbPowerSavingMode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/light_sens_9" >
</CheckBox>
In this way it doesn't work:
<CheckBox
android:id="#+id/cbPowerSavingMode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/light_sens_9" >
</CheckBox>
<TextView
android:id="#+id/tvInstructions"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/impostazioni_19"
android:textColor="#FF0000"
android:textStyle="bold" />
What's the problem?

Resource not found excpetion for Android Style for Button

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 would recommend you update the ADK's libraries. This question's answer details how to update your libraries.
Furthermore, verify that the libraries you imported for com.google.android.maps have been added to your build path. It seems an off thing to check but working with Android, I have seen many stranger things!
Edit: As stated by one of the comments, the deprecated maps library might be the culprit. If the update does not fix the problem. Try raising the minimum version you are targeting. Legacy support is nice but often induces more problems than it solves. Unless it is of crucial importance to you, I would personally only target the latest release which I believe was API version 14 or 16.

yup as Raghunandan said you are using Google maps API V1 which is deprecated one. Follow this link for Convert it to API V2.
And also you can try this code which I got map on my emulator.

Selecting an item in ListFragment list programmatically

I've made my Android app tablet optimized and I followed the tutorial here:
Everything is great, but I am trying to select an item (say, the 1st item) with a button in the ActionBar.
I tried this answer to use performItemClick but on I've got error reports of java.lang.IllegalStateException
in android.support.v4.app.ListFragment.ensureList, java.lang.IllegalStateException: Content view not yet created, and java.lang.NullPointerException
in android.content.ComponentName.<init>
I've tried checking if the ListView is null and still get the error reports on the Play Store. How do I properly select an item in my list programmatically?
Update to add logcat and the code is virtually identical to the tutorials in the links:

Update 2
And here is the code that is causing the problem:
if (mListFragment.listView != null) {
mListFragment.listView.performItemClick(mListFragment.listView.getAdapter().getView(position, null, null), position, mListFragment.listView.getAdapter().getItemId(position));
}

Google map application program crashes at the launch

I have been trying to add a map to my application, I have followed instructions on the android developers HelloGoogleMaps tutorial but my map is just force closing when I run the maps option. I have obtained my api key logged permissions in manifest
<?xml version="1.0" encoding="utf-8"?>

Can some one tell if any thing needs to be configured in addition to run the code?

this is what I can see in logcat..
this what I have in mappingDemoActivity.java
public class MappingDemoActivity extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//add listners for all buttons
View firstbutton= findViewById(R.id.geocode_button);
firstbutton.setOnClickListener((OnClickListener) this);
View secondButton = findViewById(R.id.latlong_button);
secondButton.setOnClickListener((OnClickListener) this);
View thirdButton = findViewById(R.id.presentLocation_button);
thirdButton.setOnClickListener((OnClickListener) this);
}
public void onClick(View v)
{
switch(v.getId())
{
case R.id.geocode_button:
Log.i("Button","Button 1 pushed");
Intent j = new Intent(this, ShowTheMap.class);
startActivity(j);
break;
case R.id.latlong_button:
Log.i("Button","Button 2 pushed");
Intent k = new Intent(this, ShowTheMap.class);
startActivity(k);
break;
case R.id.presentLocation_button:
Log.i("Button","Button 3 pushed");
Intent m = new Intent(this, MapMe.class);
startActivity(m);
break;
}
}

<uses-permission> tag needs to be a child of <manifest>, not <application>.
Try change <uses-permission> position, it can help.

Remove this code which is inside <intent-filter>
`<uses-library android:name="com.google.android.maps" />`
Because it is Already there in Below Quote.

Have a look at the Google MapsDemo that is included in the SDK my path is:
C:\android-sdk\add-ons\addon-google_apis-google_inc_-10\samples\MapsDemo
I had a quite anoying problem (MapActivity crashes on some devices) that was only showing up on certain(!) Android devices and also not in the Emulator. What I did was, to strip down the working demo until it was similar to my basic example. Then it turned out that Samsung phones don't accept package names not starting with com., while other devices (HTC Flyer) do! But this is not your problem, since you are using a com. package name.
There might be one more thing that comes to my mind. You didn't post your main.xml. If you use a nested LinearLayout below the MapView this also crashes the app. On top of the MapView it works fine. So in case you are using something like:
<LinearLayout ... >
<com.google.android.maps.MapView ... />
<LinearLayout ... >
<Button .../>
</LinearLayout>
</LinearLayout>
This could cause your problem. This is reproducable and throws exactly the same java.lang.ClassCastException error.
Also be sure to have your < uses-permission > and < uses-library > statements in the right place, as the guys said before. The first one must be a direct child of the < manifest > node. The second one must be a direct child of the < application > node.
I hope this helps you. I was going crazy with this stuff.
