Body
I have a class called FileGeneration that extends Activity In FileGeneration I have a method called <pre><code>protected OutputStream openAndWriteFile() { // Set the Context-mode int cxt = Context.MODE_PRIVATE; // Check if we are not going to clear the file and the file exists if (!clearFile && (new File(this.fileName)).exists()) { // Append to the file cxt = Context.MODE_APPEND; } // Try to open the file to write to try { // Open the File using the Context this.os = openFileOutput(this.fileName, cxt); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } // Return the OutputStream return this.os; } </code></pre> And I get this output in Logcat <pre><code>06-08 15:31:43.733: ERROR/AndroidRuntime(2850): java.lang.NullPointerException 06-08 15:31:43.733: ERROR/AndroidRuntime(2850): at android.content.ContextWrapper.openFileOutput(ContextWrapper.java:158) 06-08 15:31:43.733: ERROR/AndroidRuntime(2850): at android.content.ContextWrapper.openFileOutput(ContextWrapper.java:158) 06-08 15:31:43.733: ERROR/AndroidRuntime(2850): at dataconnection.FileGeneration.openAndWriteFile(FileGeneration.java:278) </code></pre> Line 278 in the class is <pre><code>this.os = openFileOutput(this.fileName, cxt); </code></pre> But when I just print the method with the paramters out in Logcat it says <pre><code>openFileOutput(Preferences.xml, 1); </code></pre> The file does not exist, but openFileOutput says it will create it, if it does not exist What can be wrong?

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.
