Trying to rename an element in SQLite Database crashes the app

I have an SQLite databse in my app which holds some data in it. I am trying to rename something inside the table and this is how I'm trying to do it:
public void renameName(String newName, String oldName){
db.execSQL("UPDATE "+SQLiteHelper.MUSIC_TABLE_NAME+" SET "+SQLiteHelper.MUSIC_NAME+"='"+newName+"' WHERE "+SQLiteHelper.MUSIC_NAME+"='"+oldName+"'");
}
I'm calling this method like this:
Log.i("TAG", "Trying to rename "+element.getTitle()+" to "+renameTo);
db.renameName(renameTo, element.getTitle());
My app crashes when I call this. As you can see I call log.i to see if those variables are null but they are NOT (I get the null pointer exception).
Here's the logcat file:

Open your database first before using it, it's the database that is null and not the strings.

Decompiled and imported into Eclipse and got instantiation error

I am a newbie to Android App programming. I decompiled an APK and imported into Eclipse. I ran it on an Android emulator and I got the message below on Logcat. Can someone give me an idea where to start looking. The app works on the Android phone. Thanks.

java.lang.NullPointerException 06-30 15:17:04.346:

you will see that a NullPointerException is thrown in line 16 of your activity firstl.
Please post your code of the firstl activity if you need more help on that.

as after seeing your logcat these maybe possible
CASE 1: make sure you are setting right layout:
public class firstl extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// The activity is being created.
setContentView(R.layout.main);//MAKE SURE YOU ARE SETTING RIGHT LAYOUT
}
CASE 2: make sure you are using right id for views accessing in code as define in xml layout
CASE 3: make sure you are registering Activity with right name in Manifest.xml :
<Activity android:name=".firstl" />

ethe App. crashs after adding google maps tag in the xml file

After adding the following lines to the .xml file, the App crashs.
And how to get the map api key??
Any suggestions.
.xml code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

You haven't posted the LogCat output, so it's hard to know why it is crashing, but it's probably because you've left the comment in there for the Maps key.
Here's a tutorial explaining how to get a (free) Google Maps API key, to insert into your app. Note that you generally need TWO. One is for your app when it's in debug mode (using the debug signing key). the other is for when you use a production version of the app (signed with a production signing key).

application has stopped unexpectedly

When I run my android application it gives an error "The application has stopped working,please try again". Please help me to solve this problem. i have created a method which gets called when the button gets clicked. When I include the code for calling another class in this method it shows the above error & when I remove that code it neither shows the error nor goes ahead when listview etc. gets clicked. Can you please check my code and help me please.
CODE:
public void myClickHandler(View view)
{
//Toast.makeText(this, "yesss",Toast.LENGTH_LONG).show();
setContentView(R.layout.screen1);
ListAdapter adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, city);
ListView FirstProjectActivity = (ListView) findViewById(R.id.mylist1);
FirstProjectActivity.setAdapter(adapter);
Intent myIntent = new Intent(FirstProjectActivity.this,
City.class);
FirstProjectActivity.this.startActivity(myIntent);
//startActivity(new Intent(FirstProjectActivity.this, City.class));
}
LOGCAT is as follows:

When you want to detect if you click on an item you need to implement the onItemClickedListener i will give you an example below like i would do it:
listView.setOnItemClickListener(new MyOnitemClickListener());
//no i make my own class that impelemnts the onitemclicklistener
public class MyOnitemClickListener implements OnItemClickListener {
private int position = 0;
public void onItemClick(AdapterView<?> parent, View view, int pos,
long lat) {
// clicked on parent.getid()
if (parent.getId() == R.id.listView) {
//do something
}
}
}

after a crash, try looking for the first couple of red lines the LOGCAT spews to you as they usually explain what happened.
the following line :
java.lang.NullPointerException
(in line 5) showed up on you log, it usually means your trying to use an uninitialized object.
refer to:
What is a NullPointerException, and how do I fix it?
