    <p>I'm creating an app that lets users pick a picture from the phone gallery. All works fine for images on the SD card but when the user selects a picture from Picassa, the application crashes.</p> <p>Code for calling gallery:</p> <pre><code>Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); startActivityForResult(i, SELECT_FROM_GALLERY_ACTION); </code></pre> <p>Code for receiving image:</p> <pre><code>Uri selectedImage = data.getData(); String[] filePathColumn = {MediaStore.Images.Media.DATA}; Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null); cursor.moveToFirst(); int columnIndex = cursor.getColumnIndex(filePathColumn[0]); String filePath = cursor.getString(columnIndex); cursor.close(); File galeryFile = new File(filePath); FileUtils.copyFile(galeryFile, imageFile); processImage(imageFile); </code></pre> <p>Errror:</p> <pre><code>08-30 14:51:04.268: E/ActivityThread(31379): Failed to find provider info for com.android.gallery3d.provider 08-30 14:51:04.278: E/AndroidRuntime(31379): FATAL EXCEPTION: main 08-30 14:51:04.278: E/AndroidRuntime(31379): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=4353, result=-1, data=Intent { dat=content://com.android.gallery3d.provider/picasa/item/5735585761449205042 flg=0x1 }} to activity {com.example.my_gallery_app/com.example.my_gallery_app.MainActivity}: java.lang.NullPointerException </code></pre> <p>Null pointer occures on line:</p> <pre><code>cursor.moveToFirst(); </code></pre> <p><a href="http://jimmi1977.blogspot.hu/2012/01/android-api-quirks-getting-image-from.html" rel="nofollow">I read this workaround.</a> But comments aren't promising. I would like to restrict gallery from showing the user Facebook, Picassa or other pictures and let her pick images only from the SD card.</p>

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.
