So I have an SQLite database. I try to update and there is no error in my android application. When I update only the name or the cost, it successfully updated but the image not showing in my gridview. But when I Update only the image, it is successfully updated.Can someone please help me out here!
this my Database Class:
public class Database extends SQLiteOpenHelper {

public static final String KEY_HARGA_PRODUK = "harga_produk";
public static final String KEY_GAMBAR_PRODUK = "gambar_produk";
//for showing 1 product
public ModelProduk getnama(int selection) {
SQLiteDatabase db = this.getReadableDatabase();
String cb = "SELECT * FROM " + TABLE_PRODUK + " WHERE " + KEY_ID_PRODUK + "= '" + selection + "'";
Cursor cursor = db.rawQuery(cb, null);
if (cursor != null)
cursor.moveToFirst();

modelProduk.set_id(Integer.parseInt(cursor.getString(0)));

Hello I am getting this strange error in my app. The first time the application starts it runs however when I store a photo from the camera the app crashes and shows this log. The app takes photo from the camera or gallery and saves them in the database and displays the photo in a custom gridview.

Can someone please help. I searched but I could not find a solution
Your problem is that you are storing path in CAMERA_PATH, which is string and trying to get a Blob. There is a type mismatch and thats why the error is thrown.
You need to insert a blob in the CAMERA_PATH before you try retrieving a blob from there.
before i'm so sorry if my post maybe duplicated, but i have another case in this problem, i wanna show an image that i capture from camera in ImageView and after that i save it or upload it into my json file, but after i take the picture, it's stopped in Log.i ("Error", "Maybe Here");
no error in my code but the image cant saved into thumbnail ImageView

I think your activity just got restarted you need to put below code in manifest where you declare. and save your uri on saveInstanceState and restore it on onrestoreinstancestate. it will be resolve your issue
android:configChanges="orientation|keyboardHidden|screenSize"
Use this lib,Provides support above API 14

I am loading pictures (below ~3MB in size) into Cardview from a database and it was infalte in Listviewstview.
The loading and browsing of these pictures is way too slow.
Is there any method to downscale these pictures to speed up & sometimes dispalyind [Duplicate] images on other card view?

Try scale your bitmap to lower its actual resolution, I've used the following codes to reduce bitmap's size.
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
For you case, add the following codes into your adapter class AsyncTask's doInBackground method
try {
bitmap = BitmapFactory.decodeStream((InputStream) new URL(args[0]).getContent());
int nh = (int) (bitmap.getHeight() * (512.0 / bitmap.getWidth()));
Bitmap scaled = Bitmap.createScaledBitmap(bitmap, 512, nh, true);
} catch (Exception e) {
e.printStackTrace();
}
return scaled;
Return scaled bitmap instead of original bitmap.

How can I capture a video recording on Android?

and there are also many links which tell about video recording but got no any clue how to use the remote IP camera to record video.
By using different samples on stackoverflow I become able to take picture and save on sdcard but couldn't record video.
If any one has any idea or code along with required files I will be thankful.
For example the url I am using where the IP camera is available is given below:
http://trackfield.webcam.oregonstate.edu/axis-cgi/mjpg/video.cgi?resolution=800x600&%3bdummy=1333689998337
