    <p>I am trying to save a bitmap to a file and then saving it on sd-card. Here's my code:</p> <pre><code>String path = Environment.getExternalStorageDirectory().toString(); File file = new File(path, "Jhs"+".jpg"); file.mkdir(); OutputStream fOut; try { fOut = new FileOutputStream(file); BitmapMatrix convMatrix = new BitmapMatrix(0); convMatrix.result.compress(Bitmap.CompressFormat.JPEG, 100, fOut); fOut.flush(); fOut.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } </code></pre> <p>Also this code is in a class which does not extend Activity.I am just giving this information thinking that maybe there is some issue with this. Here's my LogCat</p> <pre><code>05-01 18:00:22.555: W/System.err(31392): java.io.FileNotFoundException: /mnt/sdcard/Jhs.jpg (Permission denied) 05-01 18:00:22.555: W/System.err(31392): at org.apache.harmony.luni.platform.OSFileSystem.open(Native Method) 05-01 18:00:22.555: W/System.err(31392): at dalvik.system.BlockGuard$WrappedFileSystem.open(BlockGuard.java:232) 05-01 18:00:22.555: W/System.err(31392): at java.io.FileOutputStream.&lt;init&gt;(FileOutputStream.java:94) 05-01 18:00:22.555: W/System.err(31392): at java.io.FileOutputStream.&lt;init&gt;(FileOutputStream.java:66) 05-01 18:00:22.555: W/System.err(31392): at com.example.imageprocess.BitmapMatrix.computeConvolution3x3(BitmapMatrix.java:123) 05-01 18:00:22.555: W/System.err(31392): at com.example.imageprocess.MainActivity.sharpen(MainActivity.java:105) 05-01 18:00:22.555: W/System.err(31392): at com.example.imageprocess.MainActivity.onCreate(MainActivity.java:51) 05-01 18:00:22.555: W/System.err(31392): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1072) 05-01 18:00:22.555: W/System.err(31392): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1836) 05-01 18:00:22.555: W/System.err(31392): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1893) 05-01 18:00:22.555: W/System.err(31392): at android.app.ActivityThread.access$1500(ActivityThread.java:135) 05-01 18:00:22.555: W/System.err(31392): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1054) 05-01 18:00:22.555: W/System.err(31392): at android.os.Handler.dispatchMessage(Handler.java:99) 05-01 18:00:22.565: W/System.err(31392): at android.os.Looper.loop(Looper.java:150) 05-01 18:00:22.565: W/System.err(31392): at android.app.ActivityThread.main(ActivityThread.java:4389) 05-01 18:00:22.565: W/System.err(31392): at java.lang.reflect.Method.invokeNative(Native Method) 05-01 18:00:22.565: W/System.err(31392): at java.lang.reflect.Method.invoke(Method.java:507) 05-01 18:00:22.565: W/System.err(31392): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:849) 05-01 18:00:22.565: W/System.err(31392): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:607) 05-01 18:00:22.565: W/System.err(31392): at dalvik.system.NativeStart.main(Native Method) </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).
