How to upload this gridview of base 64 converted images to firebase?

This is the code I am working on, make a multiple selection of images and the most in a gridview array that calls it ImageList, but I would recommend converting the images to a base64 to have more efficiency when uploading and displaying the images, so I looked for examples and documentation and I found a way to convert them, but I was somewhat confused, because the array where the images are stored was ready List of images I had to pass it to a chain of chains, but I did not understand very well how to upload them to the firebase both the storage and the database, since they are images that will be saved of products that will be shown in the store this is the code
here is the activity where the data will be uploaded, the data as name price and description already uploaded to the database the imagenes not.
public class adminActivity extends AppCompatActivity {
private EditText nombreP, precioP, infoP;
int PICK_IMAGE = 100;

private String convertirUriToBase64(Bitmap bitmap) {

ClipData clipData = data.getClipData();
if (resultCode == RESULT_OK && requestCode == PICK_IMAGE){
/*PARA UNA SOLA IMAGEN*/
if (clipData == null){

listaImagenes.add(imagenUri);
}
}else {
/*PARA VARIAS IMAGENES*/
for (int i = 0; i < clipData.getItemCount(); i++){
listaImagenes.add(clipData.getItemAt(i).getUri());
}
}
baseAdapter = new GridViewAdapter(adminActivity.this, listaImagenes);
gvImagenes.setAdapter(baseAdapter);
}
}
and here is the gridview adapter code
#Override
public int getCount() {
return listaImagenes.size();
}
#Override
public Object getItem(int position) {
return listaImagenes.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(final int position, View view, ViewGroup parent) {
if (view == null){
layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
view = layoutInflater.inflate(R.layout.item_carga_imagenes, null);
}
ImageView ivImagen = view.findViewById(R.id.ivImagen);
ImageButton ibtnEliminar = view.findViewById(R.id.ibtnEliminar);
ivImagen.setImageURI(listaImagenes.get(position));
ibtnEliminar.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
listaImagenes.remove(position);
notifyDataSetChanged();
}
});
return view;
}
}
here i point out the method where i try to make the connection to the storage of firebase, they could help to rebuild it in order to be able to upload them to the storage and also to the database with their respective name, price and description
private void enviarImagen(final String cadena) {
StorageReference folderRef = mStorageRef.child("imagenesProductos");
folderRef.putFile((Uri) listaImagenes).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
Task<Uri> uriTask = taskSnapshot.getStorage().getDownloadUrl();
while (!uriTask.isSuccessful());
Uri downloadUri = uriTask.getResult();
}
});
}

Your question is still little bit of confusion, In my case what i understand from you, you want to store images to firebase in BASE64 format.
String encode = Base64.encodeToString(bytes, Base64.DEFAULT);
Now, you don't have you store string, you can simply store byte[] in firbase and retrive it and just converted it to bitmap, here is a example for you:
byte[] byteImage = Base64.decode(encode, Base64.DEFAULT);
Bitmap imageBitmap = BitmapFactory.decodeByteArray(byteImage, 0, decodedString.length);

How to remember bitmap Uri

i'm trying to do an activity which can show picture from gallery. But my Activity needs to remember bitmap uri for another time so it can always open that picture.
here is my .java
edited
i added something else to convert uri to string then string to uri but it doesn't work. Can someone help?
public class DersProgram extends Activity { private static int RESULT_LOAD_IMAGE = 1;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dersprogrami);

buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri uri = data.getData();
String BitmapURI;
BitmapURI = uri.toString();
uri = Uri.parse(BitmapURI);
SharedPreferences sharedPreferences = getSharedPreferences("BitmapURI", Context.MODE_PRIVATE);
sharedPreferences.edit().putString("BitmapURI", "your URI as a String").apply();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.resim);
Bitmap bmp = null;
try {
bmp = getBitmapFromUri(uri);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
imageView.setImageBitmap(bmp);
}
}
private Bitmap getBitmapFromUri(Uri uri) throws IOException {
ParcelFileDescriptor parcelFileDescriptor =
getContentResolver().openFileDescriptor(uri, "r");
FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
parcelFileDescriptor.close();
return image;
}
}
I want to open picture which is called before. Please help me(also i am a beginner) sorry for my English.

As said, use SharedPreferences.
store your bitmapURI as a String in your Activity:
SharedPreferences sharedPreferences = getSharedPreferences("some string", Context.MODE_PRIVATE);
sharedPreferences.edit().putString("BitmapURI", "your URI as a String").apply();
and retrieve it whenever your want:
String bitmapURI = sharedPreferences.getString("BitmapURI", "default string if BitmapURI is not set");

Retrieving data from Parse

I manage to have the user record information name, headline, age, and even gender selection as well as gender preference in parse. Now I want to be able to retrieve the information, with conditions. For instance, if the current user selected that he is looking for a female, than it would only display queryequal female.
Below is the code where the user enter the information that is submitted to parse:

Below is the code that I am brainstorming could be used to retrieved information:
currentUserId = ParseUser.getCurrentUser().getObjectId();
names = new ArrayList<String>();
// String userActivitySelectionName = "";
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.whereNotEqualTo("objectId", currentUserId);
query.whereEqualTo("ActivityName","");
query.whereNotEqualTo("Looking_Gender",currentUserID);
The issue i have now is setting a condition, where if a guy wants to be match with guy so only those guys who want to be match with guys information returns, and vice-versa for women.
Let me know, if this is fine.
Thanks in advance.

The following line will ensure that the Users returned are only users who match the gender for which the current user is looking. That is, if I'm looking for a female, the constraint below will ensure that only females are returned.
query.whereEqualTo("Gender", ParseUser.getCurrentUser().getString("Looking_Gender"));
The following line will ensure that the Users returned are only users who are looking for other users that match the gender for which I am. That is, if I'm a male, the constraint below will ensure that only users who are looking for males will be returned.
query.whereEqualTo("Looking_Gender", ParseUser.getCurrentUser().getString("Gender"));
If I understand your question correctly, using the above two constraints together should achieve what you're looking for.

How to open the camera with more than one button click in Android?

I created camera application in Android. I have created one activity and 3 buttons and 3 image view are included in the same activity. When I have to take snap click on first button that snap will display in first image view, then when I take snap on click second button that snap will display in second image view and same as to third button.
When I run my app camera open success fully and take the snap also done but it can't display in image view same as to another buttons also. Here is my code.
Here is my Activity Code
public class Take_Snap_Page extends Activity
{
ImageView imgPersonalSnap;
ImageView imgAddressProofSnap;
ImageView imgPanCardProofSnap;
ImageView imgHideBitmap;
Button btnPersonal ;
Button btnAddress;
Button btnPanCard;
Button btnSubmitSnap;
Bitmap bp;
Bitmap bitmap ;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.take_snap);
imgPersonalSnap = (ImageView)findViewById(R.id.imagesPersonnalSnap);
imgAddressProofSnap = (ImageView)findViewById(R.id.imageAddressProofSnap);
imgPanCardProofSnap = (ImageView)findViewById(R.id.imagePanCardproofSnap);
imgHideBitmap = (ImageView)findViewById(R.id.imgHide);
btnPersonal = (Button)findViewById(R.id.buttonCapture_Personal_Snap);
btnPersonal.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
imgPersonalSnap.setImageBitmap(bitmap);
}
});
btnAddress = (Button)findViewById(R.id.buttonCapture_AddressSnap);
btnAddress.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
}
});
btnPanCard = (Button)findViewById(R.id.buttonCapture_PanCardSnap);
btnPanCard.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open();
}
});
}
public void open() {
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, 0);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0)
{
if (resultCode == RESULT_OK && data !=null )
{
// ... now let's see use the picture at data/
bp = (Bitmap) data.getExtras().get("data");
imgHideBitmap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
}
}
}
}

Try wit requestCode as like following.
btnAddress.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(0);
}
});
btnAddress.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(1);
}
});
btnPanCard.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
open(2);
}
});
And
public void open(int requestCode) {
Intent intent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, requestCode);
}
And
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0)
{
if (resultCode == RESULT_OK && data !=null )
{
// ... now let's see use the picture at data/
switch(requestCode){
case 0:
bp = (Bitmap) data.getExtras().get("data");
imgPersonalSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
case 1:
bp = (Bitmap) data.getExtras().get("data");
imgAddressProofSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
case 2:
bp = (Bitmap) data.getExtras().get("data");
imgPanCardProofSnap.setImageBitmap(bp);
BitmapDrawable drawable = (BitmapDrawable) imgHideBitmap.getDrawable();
bitmap = drawable.getBitmap();
break;
}
}
}
}

Zbar Qr Code Reader - crash after qr code reader

I'm trying to do a Qr code reader with Zbar but the app crash after the Qr Code detect (when result != 0)
I'm not getting error message, only a warning:
CHECK surface infomation creating=false formatChanged=false
sizeChanged=false visible=false visibleChanged=true
surfaceChanged=true realSizeChanged=false redrawNeeded=false
left=false top=false
Here is the code which I got the crash
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Camera.Size size = parameters.getPreviewSize();
Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);
int result = mScanner.scanImage(barcode);
if (result != 0) {
mCamera.cancelAutoFocus();
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
mPreviewing = false;
SymbolSet syms = mScanner.getResults();
for (Symbol sym : syms) {
String symData = sym.getData();
if (!TextUtils.isEmpty(symData)) {
Intent dataIntent = new Intent();
dataIntent.putExtra(SCAN_RESULT, symData);
dataIntent.putExtra(SCAN_RESULT_TYPE, sym.getType());
setResult(Activity.RESULT_OK, dataIntent);
finish();
break;
}
}
}
}

I did update my code and it works great! thx all!
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Camera.Size size = parameters.getPreviewSize();
Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);
int result = mScanner.scanImage(barcode);
if (result != 0) {
mCamera.cancelAutoFocus();
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
mPreviewing = false;
SymbolSet syms = mScanner.getResults();
for (Symbol sym : syms) {
String symData = sym.getData();
Log.i("url qr code",symData);
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(symData));
startActivity(browserIntent);
break;
}
}
}

try this... for Qr Reader....
public class QRCodeActivityTest extends Activity implements
OnQRCodeReadListener {
QRCodeReaderView qrView;
TextView tvQr;
Image_Sql sql;
String Description;
#Override

qrView.setOnQRCodeReadListener(this);
tvQr = (TextView) findViewById(R.id.txtqr);
sql= new Image_Sql(this);
sql.Open();
}
