How to store and get image into/from a SQLite database android

I am inside a fragment and I have a CircleImageView to which I have set an image in xml by default using android:src="#drawable/default_profile_image".
The user can decide whether to load another image and I do it by launching an intent that opens the gallery and in the onActivityResult() I load the image in this way:
if(requestCode==0 && resultCode == Activity.RESULT_OK) {
Uri path = data.getData();
Bitmap photo = null;
try {
photo = MediaStore.Images.Media.getBitmap(getContext().getContentResolver(), path);
} catch (IOException e) {
e.printStackTrace();
}
if(photo != null)
mProfilePhoto.setImageBitmap(photo);
}
Now whether the user has uploaded another image or left the default image, I would like to save it in the database, and then take it.
I already have a method that takes the name from the database correctly.
private void getUserInformation(){
Cursor data = databaseHelper.getUserInformation();
if(data.moveToFirst()) {
//this crash
Bitmap bitmap = BitmapFactory.decodeByteArray(data.getBlob(2), 0, data.getBlob(2).length);
if(bitmap != null)
mProfilePhoto.setImageBitmap(bitmap);*/
mProfileName = data.getString(1);
}
data.close();
}
This is what I have for the moment that does not work
onclick method inside the fragment
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.saveProfileButton:
//need to pass a bitmap insted of null
addUserInformation(name,null);
break;
case R.id.profile_photo:
Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
try {
startActivityForResult(
Intent.createChooser(i, "Select Picture"), 0);
}catch (ActivityNotFoundException ex){
ex.printStackTrace();
}
break;
}
}
private void addUserInformation(String username, Bitmap profile_pic){
boolean b = databaseHelper.addUserInformation(username, profile_pic);
if(b) {
toastMessage("Update Success");
}
else
toastMessage("Update Failed");
}
DatabaseHelper class
public class DatabaseHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAME = "userinfo";
private static final int DATABASE_VERSION = 1;
private static final String TABLE_NAME1 = "USER_INFORMATION";
public DatabaseHelper(Context context) {
super(context,DATABASE_NAME,null,DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table "+TABLE_NAME1+" (ID INTEGER PRIMARY KEY AUTOINCREMENT, USERNAME TEXT, PICTURE BLOB)");
}
#Override
public void onUpgrade(SQLiteDatabase db, int i, int i1) {
db.execSQL("DROP TABLE IF EXISTS "+TABLE_NAME1);
onCreate(db);
}
public boolean addUserInformation(String username, Bitmap picture){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("USERNAME", username);
byte[] data = getBitmapAsByteArray(picture);
values.put("PICTURE", data);
long id = db.insert(TABLE_NAME1, null, values);
db.close();
if(id == -1)
return false;
else
return true;
}
private static byte[] getBitmapAsByteArray(Bitmap bitmap) {
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 0, outputStream);
return outputStream.toByteArray();
}
}

Modify your method:
private void getUserInformation(){
Cursor data = databaseHelper.getUserInformation();
if(data.moveToFirst()) {
byte[] btyeArray = data.getBlob(2);
if(btyeArray != null) {
Bitmap bitmap = BitmapFactory.decodeByteArray(btyeArray , 0, btyeArray .length);
if(bitmap != null) {
mProfilePhoto.setImageBitmap(bitmap);
photo = bitmap;
}else
mProfilePhoto.setImageResource(R.drawable.defaultImage); // set your default Image here
} else {
mProfilePhoto.setImageResource(R.drawable.defaultImage); // set your default Image here
}
mProfileName = data.getString(1);
}
data.close();
}
in onActivityResult Bitmap photo define it as a global variable. and while calling addUserInformation send photo variable.
case R.id.saveProfileButton:
//need to pass a bitmap insted of null
addUserInformation(name, photo);
Modify your DatabaseHelper method
public boolean addUserInformation(String username, Bitmap picture){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("USERNAME", username);
if(picture != null) {
byte[] data = getBitmapAsByteArray(picture);
values.put("PICTURE", data);
}
long id = db.insert(TABLE_NAME1, null, values);
db.close();
if(id == -1)
return false;
else
return true;
}

Image not Uploading to SQLite Database

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.
public class add_gallery extends AppCompatActivity {
Button addImage;
ArrayList<Gall> imageArry = new ArrayList<Gall>();
GalleryImageAdapter imageAdapter;
private static final int CAMERA_REQUEST = 1;

// Writing Galls to log
Log.d("Result: ", log);
// add images data in arrayList
imageArry.add(cn);
}

imageAdapter = new GalleryImageAdapter(this, R.layout.gallery_list,
imageArry);
dataList.setAdapter(imageAdapter);

intent.putExtra("imagename", theImage);
startActivity(intent);

public// Adding new image to gallery

// Inserting Row
db.insert(GALLERY_TABLE, null, values);
db.close(); // Closing database connection
}
Below is the Gall class
public class Gall {
// private variables
int _id;
byte[] _image;
String _title;
String _caption;
// Empty constructor
public Gall() {
}
// constructor
public Gall(int keyId, byte[] image, String title, String caption) {
this._id = keyId;

}
public Gall(byte[] image, String title, String caption) {
this._image = image;
this._title = title;
this._caption = caption;
}
public Gall(int keyId) {
this._id = keyId;
}
// getting ID
public int getID() {
return this._id;
}
// setting id
public void setID(int keyId) {
this._id = keyId;
}
// getting image
public byte[] getImage() {

this._title = title;
}
// getting caption
public String getCaption() {

}
// setting caption
public void setCaption(String caption) {
this._title = caption;
}
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.

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();

if u want to retrive direct from gallary then use this code
http://viralpatel.net/blogs/pick-image-from-galary-android-app/
this is my method for getting all file from sdcard and u just save this in one datacontroller class ohk dude
private void getallimages()
{
String[] STAR = { "*" };
final String[] columns = { MediaStore.Images.Thumbnails._ID , MediaStore.Images.Media.DATA};
final String orderBy = MediaStore.Images.Media.DEFAULT_SORT_ORDER;
Cursor imagecursor = ((Activity) cntx).managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, STAR, null, null, orderBy);
int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID);
int imgNameIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DISPLAY_NAME);
int count = imagecursor.getCount();
for (int i = 0; i < count; i++) {
imagecursor.moveToPosition(i);
int id = imagecursor.getInt(image_column_index);
ImageItem imageItem = new ImageItem();
imageItem.id = id;
imageItem.filePath = imagecursor.getString(imagecursor.getColumnIndex(MediaStore.Images.Media.DATA));
lastId = id;
imageItem.img = MediaStore.Images.Thumbnails.getThumbnail(cntx.getContentResolver(), id,MediaStore.Images.Thumbnails.MICRO_KIND, null);
imageItem.selection = false; //newly added item will be selected by default
controller.images.add(imageItem);
}
}
this is ImageItem wrapper class
public class ImageItem {
public boolean selection=true;
public int id;
public Bitmap img;
public String filePath;
public String fileType;
}

You can try this :
public class EMView extends Activity {
ImageView img,img1;
int column_index;
Intent intent=null;
// Declare our Views, so we can access them later
String logo,imagePath,Logo;
Cursor cursor;
//YOU CAN EDIT THIS TO WHATEVER YOU WANT
private static final int SELECT_PICTURE = 1;
String selectedImagePath;
//ADDED
String filemanagerstring;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img= (ImageView)findViewById(R.id.gimg1);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
}
//UPDATED
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
//OI FILE Manager
filemanagerstring = selectedImageUri.getPath();
//MEDIA GALLERY
selectedImagePath = getPath(selectedImageUri);
img.setImageURI(selectedImageUri);
imagePath.getBytes();
TextView txt = (TextView)findViewById(R.id.title);
txt.setText(imagePath.toString());
Bitmap bm = BitmapFactory.decodeFile(imagePath);
img1.setImageBitmap(bm);
}
}
}
//UPDATED!

Image doesn't change in child activity using Activitygroup in android

In my app, I' using Tab. There are three tabs. In which 3rd tab is Activity group which has two activities. In first activity, there are two options for user. User can choose image from camera or from gallery. After selecting an image, user should move to child activity, which will display selected image in that activity. Till this app is working fine. But only problem here I'm facing is, image is not being cleared when I move back to parent activity from child activity. Means once I choose image from gallery/camera, user moves to child activity, and image is being displayed in child activity. Now when I press back button from child activity, user moves back to parent activity and again if user selects different image from galley/camera, that different image is not there in child activity. The previous image is there in child activity. Below is my code.
ABCGroup.java

replaceView(view);
}

gallery.setOnClickListener(new OnClickListener() {

public void onClick(View v)
{
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
ABCGroup.group.startActivityForResult(intent, REQUEST_ID);
}
});
camera.setOnClickListener(new OnClickListener() {

Second.java
public class Second extends Activity {
public static Bitmap bmp;
Bitmap myBitmap;
String path;

int count = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
View viewToLoad = LayoutInflater.from(Second.this.getParent()).inflate(R.layout.second, null);
Second.this.setContentView(viewToLoad);
Button btn = (Button)viewToLoad.findViewById(R.id.button1);
iv = (ImageView)viewToLoad.findViewById(R.id.imageView1);
iv.setImageBitmap(bmp);
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
path = preferences.getString("data", "");
File imgFile = new File(path);
if(imgFile.exists()){
Toast.makeText(getBaseContext(), "" + path, 1000).show();
myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
iv.setImageBitmap(myBitmap);
}
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
ABCGroup.group.back();
}
});
}
#Override
public void onBackPressed() {
super.onBackPressed();
Intent intent = new Intent(Second.this, Tab1.class);
Tab1 parentActivity = (Tab1)getParent();
parentActivity.replaceContentView("Profile", new Intent(Second.this, Tab1.class).addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY ) );
}
public void onResume()
{
super.onResume();
}
}

Finally I got the answer
public void onResume()
{
super.onResume();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
path = preferences.getString("data", "");
imgFile = new File(path);
Toast.makeText(getBaseContext(), "" + path, 2000).show();
if(imgFile.exists())
{
myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
iv.setImageBitmap(myBitmap);
}
}
