Body
my *.java : <pre><code>package com.google.multiplier; import android.os.Bundle; import android.app.Activity; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; public class Multiplier extends Activity { private EditText num1,num2,res; private int result; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_multiplier); num1=(EditText)findViewById(R.id.EditText1); num2=(EditText)findViewById(R.id.EditText2); res=(EditText)findViewById(R.id.editText3); result=(Integer.parseInt(num1.getText().toString()))*(Integer.parseInt(num2.getText().toString())); Button button1 = (Button) findViewById(R.id.button1); button1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { res.setText(Integer.toString(result)); } }); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_multiplier, menu); return true; } } </code></pre> and the layout: <pre><code><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" > <EditText android:id="@+id/EditText1" android:layout_width="100dp" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:layout_marginLeft="50dp" android:layout_marginTop="126dp" android:ems="10" android:inputType="number" /> <EditText android:id="@+id/EditText2" android:layout_width="100dp" android:layout_height="wrap_content" android:layout_alignBaseline="@+id/EditText1" android:layout_alignBottom="@+id/EditText1" android:layout_marginLeft="24dp" android:layout_toRightOf="@+id/EditText1" android:ems="10" android:inputType="number" > <requestFocus /> </EditText> <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/EditText1" android:layout_centerHorizontal="true" android:layout_marginTop="14dp" android:text="@string/bt" /> <EditText android:id="@+id/editText3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/button1" android:layout_centerHorizontal="true" android:layout_marginTop="27dp" android:ems="10" android:inputType="numberDecimal" /> </RelativeLayout> </code></pre> As you may see it is a simple multiplier. I launch it in an Android 4.0 emulator and it get force close error but the compiler did not find any error before running. How can I find where is the problem?

Guidance

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.
