    <p>I am automating a product using Robotium. In a module I have to validate the data derived.</p> <p>For that I am using this code:</p> <pre><code>class sharefirstlevel { public void A { for(int k=1;k&lt;=4;k+=2) { ExpectedResult = solo.clickInList(k); for (int i = 0; i &lt; ExpectedResult.size(); i++) { Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; solo.scrollListToLine(0, k); ExpectedResult=solo.clickInList(1); Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; ExpectedResult = solo.clickInList(2); Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; Log.d("xyz","Values of the Strings are"+Actualvalues[i].toString()); } } } } </code></pre> <p>Its extracting the values selected to an array.</p> <p>Now when its derived, to validate I am using this code:</p> <pre><code>class sharedLevel { public void B { for(int i=0; i &lt;= sharefirstlevel.Actualvalues.length; i++) { Log.d("xyz","Values are:"+sharefirstlevel.Actualvalues[i]); actual=solo.searchText(sharefirstlevel.Actualvalues[i]); assertEquals(expected, actual); Log.d("xyz","Values are:"+sharefirstlevel.Actualvalues[i]); } } } </code></pre> <p>The values are getting extracted to the array and when printed, the proper values are getting inseted to the array and are even getting passed to another class.</p> <p>But the execution of the junit test case will be successful only for 1 or 2 times. But from then i am getting a null pointer exception. Please help me. Am at a fix!!</p> <p>The first value while getting inserted to the ArrayList itself is null. Here is the Code:</p> <pre><code> for(int k=1;k&lt;=4;k+=2) { ExpectedResult = solo.clickInList(k); for (int i = 0; i &lt; ExpectedResult.size(); i++) { Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; solo.scrollListToLine(0, k); ExpectedResult=solo.clickInList(1); Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; ExpectedResult = solo.clickInList(2); Actualvalues[i] += ExpectedResult.get(i).getText().toString() + " "; Log.d(" ","Values of the Strings are"+Actualvalues[i].toString()); } } </code></pre> <p>The value getting inserted at the first line within the for loop itself is null. Hence the problem.</p> <p>But I am not getting, why null value is being inserted at 0th position. Please help me out for solutions.</p>

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.
