    <p>I used this code to capture an image from the camera.</p> <pre><code>package android.takeowneship; import java.io.File; import android.app.Activity; import android.content.ContentValues; import android.content.Intent; import android.database.Cursor; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.net.Uri; import android.os.Bundle; import android.provider.MediaStore; import android.widget.ImageView; import android.widget.Toast; public class camera extends Activity{ private static final int CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE = 100; Uri imageUri; private ImageView imageView; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.main); //define the file-name to save photo taken by Camera activity String fileName = "new-photo-name.jpg"; //create parameters for Intent with filename ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera"); //imageUri is the current activity attribute, define and save it for later usage (also in onSaveInstanceState) imageUri = getContentResolver().insert( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); //create new Intent Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE) { if (resultCode == RESULT_OK) { //use imageUri here to access the image Toast.makeText(this, "picture has been taken"+ imageUri, Toast.LENGTH_SHORT).show(); } else if (resultCode == RESULT_CANCELED) { Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(this, "Picture was not taken", Toast.LENGTH_SHORT).show(); } } } public static File convertImageUriToFile (Uri imageUri, Activity activity) { Cursor cursor = null; try { String [] proj={MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID, MediaStore.Images.ImageColumns.ORIENTATION}; cursor = activity.managedQuery( imageUri, proj, // Which columns to return null, // WHERE clause; which rows to return (all rows) null, // WHERE clause selection arguments (none) null); // Order-by clause (ascending by name) int file_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); // int orientation_ColumnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.ImageColumns.ORIENTATION); if (cursor.moveToFirst()) { // String orientation = cursor.getString(orientation_ColumnIndex); return new File(cursor.getString(file_ColumnIndex)); } return null; } finally { if (cursor != null) { cursor.close(); } } } </code></pre> <p>}</p> <p>But in this code it opens the camera and user has to click the button to take the photo. What I want is to take the photo automatically (without a preview) and saves it in the memory card.</p>

    1. COHave you considered that this is actually a security measurement? Why do you think this is possible at all? Also, why do you need that?

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).
