    <p>Im working off the Android camera tutorial, SDK 11. For some reason I'm getting a Null Pointer within handleCameraPhoto(). The only thing I see is "Failure delivering result ResultInfo{who=null, request=100, result=-1, data=null} to activity", but I can't sort out why.</p> <pre><code>&lt;uses-permission android:name="android.permission.CAMERA" /&gt; &lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/&gt; </code></pre> <p>Activity:</p> <pre><code>@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_camera); // create Intent to take a picture and return control to the calling application Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); fileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE); // create a file to save the image intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri); // set the image file name ///Toast.makeText(this, "File Uri"+fileUri.toString(), Toast.LENGTH_LONG).show(); // start the image capture Intent startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); } @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) { if (resultCode == RESULT_OK) { // Image captured and saved to fileUri specified in the Intent handleCameraPhoto(data); } else if (resultCode == RESULT_CANCELED) { // User cancelled the image capture finish(); } else { // Image capture failed, advise user finish(); Toast.makeText(this, "Image capture failed, quiting", Toast.LENGTH_LONG).show(); } } } /** * * @param intent */ private void handleCameraPhoto(Intent data) { Toast.makeText(this, "Image saved to:\n" + data.getData(), Toast.LENGTH_LONG).show(); } /** Create a file Uri for saving an image or video */ private static Uri getOutputMediaFileUri(int type){ return Uri.fromFile(getOutputMediaFile(type)); } /** Create a File for saving an image or video */ private static File getOutputMediaFile(int type){ // To be safe, you should check that the SDCard is mounted // using Environment.getExternalStorageState() before doing this.

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).
