    <p>I hava a Android app @ Android Market. And Im keep getting some crash reports that claims that some users get a NullPointerException.</p> <p>I've located the code that seems to be causing this problem.</p> <p>It's in a ArrayAdapters getView method. </p> <pre><code>if (v == null) { LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.subcatategory_row, null); holder = new ViewHolder(); v.setTag(holder); } else { holder=(ViewHolder)v.getTag(); if(holder == null){ holder = new ViewHolder(); } } TextView tl = (TextView) v.findViewById(R.id.label); tl.setTextAppearance(getContext(), R.style.styleA); </code></pre> <p>The last line in this snippet seems to be causing the crash. However I've never experienced it, and I've been testing it on several devices. </p> <p>Help would be greatly appreciated!!</p> <p>EDIT:</p> <p>subcategory_row.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/row_layout" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="0dip" android:background="@drawable/background" android:weightSum="80"&gt; &lt;TextView android:id="@+id/label" android:layout_weight="9" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_marginRight="6dip" android:gravity="center_vertical|center" android:text="C.r" android:textSize="12sp" android:textColor="@color/default_textcolor" /&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="53" android:layout_height="fill_parent"&gt; &lt;TextView android:id="@+id/text_bb" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:layout_marginLeft="4dip" android:gravity="bottom" android:textSize="13sp" android:textColor="@color/default_textcolor" android:ellipsize="end" android:singleLine="true"/&gt; &lt;TextView android:id="@+id/text_ba" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:layout_marginLeft="4dip" android:gravity="top" android:textSize="13sp" android:textColor="@color/default_textcolor" android:ellipsize="end" android:singleLine="true"/&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="8" android:layout_height="fill_parent" &gt; &lt;TextView android:id="@+id/text_a" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:gravity="bottom|right" android:textSize="13sp" android:text="0" android:textColor="@color/default_textcolor" /&gt; &lt;TextView android:id="@+id/text_b" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1" android:gravity="top|right" android:textSize="19sp" android:text="0" android:textColor="@color/default_textcolor" /&gt; &lt;/LinearLayout&gt; &lt;LinearLayout android:layout_width="0dip" android:layout_height="wrap_content" android:layout_gravity="center_vertical|right" android:layout_weight="10" android:orientation="vertical" android:paddingLeft="10dp" &gt; &lt;ImageView android:id="@+id/arrow" android:layout_width="wrap_content" android:layout_height="40dp" android:paddingLeft="-10dip" android:paddingRight="10dip" android:src="@drawable/arrow" android:visibility="visible" /&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre>

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.

SQuiL has stopped working due to an internal error.

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