My app is set to only display in portrait mode. The problem is that I need to use a camera and a gallery intent and you can't specify those apps to be the same orientation so some funky stuff happens in between those orientation changes which makes my image data null.
This code works fine when the phone isn't tilted sideways (in portrait mode) how would I improve it to handle data after an orientation change?

You could use fragments to retain the information that is being lost by the orientation change.

I am trying to develop some kind of OCR application with Text Recognizing feature. I wrote and found some codes which is working properly but my problem is I want make some customization in the camera layout. I want to add my own capture button and add a frame.

In that case, what should I do ? Thank you guys.
No, you cannot change the layout of the camera app that fulfills ACTION_IMAGE_CAPTURE intent. Actually, different devices will not have same camera apps. Each may have very different look-and-feel. You need a 'custom camera' to control its layout and UX.
i have got the image directly from the camera , gallery to the image view in my app its all working fine.
Now what I want is to save this image from Image View to the application directory and also access it when required.
//You Can try This
File myDir = new File(Environment.getExternalStorageDirectory().toString() + "/yourDirectoryname");
myDir.mkdirs();
File file = new File(myDir, yourImagePath);
if (file.exists()) file.delete();
try {
FileOutputStream out = new FileOutputStream(file);
imgBitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
out.flush();
out.close();

I am new to android programming so hopefully someone can be off help. Been having issues with attempting to add an image from Gallery or Camera to my SQLite database. I stumbled across someone's GitHub who had a CameraGallerySqliteDemo
Found here
I tried to amend the code for my needs but have been unable to add an image to my gallery table.
Below is the class I am using to add images to the database.

}
Perhaps a trained eye can spot where I am going wrong, I not receiving any errors, just that the image is not being added to database table. Any help would be greatly appreciated.
Store image as byte array in the db.
Please check the example here. This might help you.
You should save your images in a folder and save their paths in you db . If you want your images to be protected and don't wanna show them in gallery as well then there are some ways like using .nomedia files or you can save your images in private folder which will not be accessible to any other app rather than yours.
I'm a newbie in Android,
I just wondering how to store an image to SQLite database in Android, well i have database look like this.
Photo
id (int) | image (BLOB)

and this a method i use to store picture in sqlite
public void addImage3(image img) {
open(); //it's mean to open the connection from database
//THE Question is right here, how i can put a byte array into database
//without using this method, a.k.a INSERT INTO, cause i have tried to search any
//solution in google, but i can't solve my problem
ContentValues values = new ContentValues();
values.put(image, img._lokasi_foto);
// Inserting Row
database.insert(Photo, null, values);
close(); // Closing database connection
}
and here's my image class
public class image {
public byte[] _lokasi_foto;
//this is getter
public byte[] getLokasi_foto() {
return _lokasi_foto;
}
//this is setter
public void setLokasi_foto(byte[] lokasi_foto) {
this._lokasi_foto = lokasi_foto;
}
and this the constructor
public image(byte[] lokasi_foto) {
this._lokasi_foto = lokasi_foto;
}
}
Can someone help me with this problem, cause i have been search in google, but i can't still solve my problem, Please Help...
Save the image in a local folder with the same name as your id. So now whenever you want to retrieve the image, just open id.jpg / id.png
private void saveToDB() {
SQLiteDatabase myDb;
String MySQL;
byte[] byteImage1 = null;
byte[] byteImage2 = null;
MySQL = "create table emp1(_id INTEGER primary key autoincrement, sample TEXT not null, audio BLOB);";
myDb = openOrCreateDatabase("Blob List", Context.MODE_PRIVATE, null);
myDb.execSQL(MySQL);
String s = myDb.getPath();
textView.append("\r\n" + s + "\r\n");
myDb.execSQL("delete from emp1");
ContentValues newValues = new ContentValues();
newValues.put("sample", "HI Hello");
try {
InputStream is = new FileInputStream("YOUR IMAGE PATH");
ByteArrayOutputStream bos = new ByteArrayOutputStream();
byte[] b = new byte[1024];
int bytesRead;
while ((bytesRead = is.read(b)) != -1) {
bos.write(b, 0, bytesRead);
}
byte[] bytes = bos.toByteArray();
textView.append("\r\n" + bytes.length + "\r\n");
newValues.put("audio", bytes);
long ret = myDb.insert("emp1", null, newValues);
if (ret < 0)
textView.append("\r\n!!! Error add blob failed!!!\r\n");
} catch (IOException e) {
textView.append("\r\n!!! Error: " + e + "!!!\r\n");
}
Cursor cur = myDb.query("emp1", null, null, null, null, null, null);
cur.moveToFirst();
while (cur.isAfterLast() == false) {
textView.append("\r\n" + cur.getString(1) + "\r\n");
cur.moveToNext();
}
// /////Read data from blob field////////////////////
cur.moveToFirst();
byteImage2 = cur.getBlob(cur.getColumnIndex("audio"));
// bmImage.setImageBitmap(BitmapFactory.decodeByteArray(byteImage2, 0,
// byteImage2.length));
textView.append("\r\n" + byteImage2.length + "\r\n");
cur.close();
myDb.close();

I want to upload a image using it's file path. Most of the tutorial I have followed regarding upload image to amazon, there is select image option(image chooser from galary). But what i need is that:
But I want to skip this step. As I know the image path and name. Suppose I have a image in a directory in the device. When user click upload photo button, it will start uploading. I want to skip select image option. But How Can I upload image to amazon storage with image path instead of selecting image (Intent image/*)?
So in short I am just wanting to use file path directly instead of select image option to upload the image in amazon.
Any help will be greatly appreciated. Thanks in advance.
Edited:
Here is my activity:
