I am building an Android app using a pile of switch statements to switch between views. Everything was going fine until I added a block of cases that cause a fatal error when the app is starting up. The cases are called by onClick statements in the XML. The offending block of cases is actually part of a block of statements that work fine. Can anyone see what I’m missing? What’s causing the fatal error? I’m including snippets of the broken code and working code along with the logCat file.

Example of the XML that would be calling the broken switch cases:
<RelativeLayout android:id="@+id/level07_layout00"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/vlayoutup"
android:visibility="gone">
<ImageButton android:id="@+id/level07_closeButton00"
android:layout_height="wrap_content"
android:background="@drawable/close"
android:layout_width="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginLeft="10dp"
android:layout_marginBottom="10dp"
android:onClick="closetomain">
</ImageButton>
<ImageButton android:id="@+id/level07_leftButton00"
android:layout_height="wrap_content"
android:background="@drawable/node"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginTop="2dp"
android:layout_marginLeft="135dp"
android:onClick="nextLayout">
</ImageButton>
<ImageButton android:id="@+id/level07_rightButton00"

android:onClick="nextLayout">
</ImageButton>
<ImageView android:id="@+id/level07_beginButton00"
android:layout_height="wrap_content"
android:background="@drawable/beginbutton"
android:layout_width="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="2dp"
android:layout_marginLeft="235dp">

<RelativeLayout android:id="@+id/level07_layout01"

android:layout_height="fill_parent"
android:background="@drawable/vlayoutup"
android:visibility="gone">

android:background="@drawable/close"
android:layout_width="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginLeft="10dp"
android:layout_marginBottom="10dp"
android:onClick="closetomain">

<ImageButton android:id="@+id/level07_rightButton01"
android:layout_height="wrap_content"
android:background="@drawable/node"
android:layout_width="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginTop="2dp"
android:layout_marginLeft="340dp"
android:onClick="nextLayout">

<ImageButton android:id="@+id/level07_backButton01"

android:layout_marginLeft="235dp"
android:onClick="prevLayout">

</RelativeLayout>
Here’s a snippet of the broken java:
case R.id.level07_backButton01:
RelativeLayout bB017 = (RelativeLayout)findViewById(R.id.level07_layout00);
bB017.setVisibility(View.VISIBLE);
RelativeLayout bB017b = (RelativeLayout)findViewById(R.id.level07_layout01);
bB017b.setVisibility(View.GONE);
break;
case R.id.level07_backButton02:
RelativeLayout bB027b = (RelativeLayout)findViewById(R.id.level07_layout01);
bB027b.setVisibility(View.VISIBLE);
RelativeLayout bB027 = (RelativeLayout)findViewById(R.id.level07_layout02);
bB027.setVisibility(View.GONE);
break;
case R.id.level07_backButton03:
RelativeLayout bB037 = (RelativeLayout)findViewById(R.id.level07_layout02);
bB037.setVisibility(View.VISIBLE);
RelativeLayout bB037b = (RelativeLayout)findViewById(R.id.level07_layout03);
bB037b.setVisibility(View.GONE);
break;
Here’s a snippet of the code that works from the same block:
case R.id.level07_backButton16:
RelativeLayout bB167 = (RelativeLayout)findViewById(R.id.level07_layout15);
bB167.setVisibility(View.VISIBLE);
RelativeLayout bB167b = (RelativeLayout)findViewById(R.id.level07_layout16);
bB167b.setVisibility(View.GONE);
break;
case R.id.level07_backButton17:
RelativeLayout bB177 = (RelativeLayout)findViewById(R.id.level07_layout13);
bB177.setVisibility(View.VISIBLE);
RelativeLayout bB177b = (RelativeLayout)findViewById(R.id.level07_layout17);
bB177b.setVisibility(View.GONE);
break;
case R.id.level07_backButton18:
RelativeLayout bB187 = (RelativeLayout)findViewById(R.id.level07_layout17);
bB187.setVisibility(View.VISIBLE);
RelativeLayout bB187b = (RelativeLayout)findViewById(R.id.level07_layout18);
bB187b.setVisibility(View.GONE);
break;
As you can see, I think, the two blocks of switch cases are the same. The part that I think is the important clue is in the logCat: VFY: invalid switch target.
If you need more information please let me know. Thanks in advance for the help!
It turned out that there were too many cases in the switch statement. I didn’t know there was a limit, but I guess there is. I broke the switch statements into separate methods and that did the trick. Thanks everyone for your suggestions!
