    <p>I had recently released an Android game in google play and I received a crash report of this <strong>NumberFormatException</strong></p> <p>I even pin pointed the code from which it is coming from.. But the thing which concerns me the most is the exception is not being thrown in any of the devices i have tested (and i have tested it in many devices)..</p> <p>I have a string file arranged like this... "10.48,1.6,90.0,1.155,1.73" where each float is separated by a comma... I don't know why this weird exception has occurred for the user of my app :(</p> <p>Here is the code which i am using to parse from the file</p> <pre><code> while(j&lt;line.length()) { if(line.charAt(j) == ',') { endingPoint = j; planetList[i].add(Float.valueOf(line.substring(startingPoint, endingPoint))); startingPoint = j+1; } else if(line.charAt(j) == 's') { i++; startingPoint = j+1; } j++; } </code></pre> <p>and here is the line which is throwing the exception...</p> <pre><code>cam = new Camera(Float.valueOf(df.format(worldWidth)),fourPointEightFixer); </code></pre> <p>HERE IS THE STACK TRACE THE KIND USER OF MY APP SENT:</p> <pre><code>java.lang.NumberFormatException at org.apache.harmony.luni.util.FloatingPointParser.parseFltImpl(Native Method) at org.apache.harmony.luni.util.FloatingPointParser.parseFloat(FloatingPointParser.java:321) at java.lang.Float.parseFloat(Float.java:323) at java.lang.Float.valueOf(Float.java:362) at com.OnMyOwn.Game.WackyGravity.&lt;init&gt;(WackyGravity.java:97) at com.OnMyOwn.Game.LevelChooserMod.initiateGame(LevelChooserMod.java:550) at com.OnMyOwn.Game.LevelChooserMod.onButtonTouchUp(LevelChooserMod.java:576) at com.OnMyOwn.Game.LevelChooserMod.update(LevelChooserMod.java:384) at com.OnMyOwn.framework.impl.GLGame.onDrawFrame(GLGame.java:165) at android.opengl.GLSurfaceView$GLThread.guardedRun(GLSurfaceView.java:1363) at android.opengl.GLSurfaceView$GLThread.run(GLSurfaceView.java:1118) </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.
