    <p>I got following error message:</p> <pre><code>main.xml: java.lang.UnsupportedOperationException </code></pre> <p>Stacktrace says:</p> <pre><code>java.lang.UnsupportedOperationException at android.graphics.Paint_Delegate.nativeGetStringBounds(Paint_Delegate.java:897) at android.graphics.Paint.nativeGetStringBounds(Paint.java) at android.graphics.Paint.getTextBounds(Paint.java:1798) </code></pre> <p>Within my code I have set up a simple test case to figure out where the problem is:</p> <pre><code>public class test extends View { public test(Context context) { super(context); // TODO Auto-generated constructor stub } public test(Context context, AttributeSet attrs) { super(context, attrs); // TODO Auto-generated constructor stub } public test(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); // TODO Auto-generated constructor stub } protected void onDraw(Canvas canvas){ super.onDraw(canvas); Paint p = new Paint(Paint.ANTI_ALIAS_FLAG); p.setColor(Color.GREEN); p.setTextAlign(Align.CENTER); canvas.drawText("hello", 100, 100, p); Rect bounds = new Rect(); p.getTextBounds("2", 0, 1, bounds); } protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){ super.onMeasure(widthMeasureSpec, heightMeasureSpec); } } </code></pre> <p>Any ideas what is going wrong?</p> <p>Heres the complete stack

    1. COI might be wrong but I'm guessing your problem isn't where you think it is. Post more of the stack trace - there's normally a 'Caused by' entry. Also, post your main.xml file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
