Open your device's Settings app. . Select Accessibility. Select Auto-rotate screen.
If you want to manually handle orientation changes in your app you must declare the "orientation" , "screenSize" , and "screenLayout" values in the android:configChanges attributes. You can declare multiple configuration values in the attribute by separating them with a pipe | character.
When you rotate your device and the screen changes orientation, Android usually destroys your application's existing Activities and Fragments and recreates them . Android does this so that your application can reload resources based on the new configuration.
same issue i was facing but using this code its work for me try this code:
Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length);
Matrix matrix = new Matrix();
matrix.postRotate(90);
Bitmap bitmapFinal=null;
bitmapFinal = Bitmap.createBitmap(bmp, 0, 0, bmp.getWidth(), bmp.getHeight(), matrix, true);
bmp.recycle();
bmp=null;
FileOutputStream fos = new FileOutputStream(pictureFile);
if(imageFormat.equals("jpg")||imageFormat.equals("jpeg"))
{
bitmapFinal.compress(Bitmap.CompressFormat.JPEG, 100,fos);
}
else if(imageFormat.equals("png"))
{
bitmapFinal.compress(Bitmap.CompressFormat.PNG, 100,fos);
}
else
{
bitmapFinal.compress(Bitmap.CompressFormat.JPEG, 100,fos);
}
bitmapFinal.recycle();
bitmapFinal=null;
fos.flush();
fos.close();
fos=null;
