How to upload two(2) image with caption to firebase database? - android

Hi guys I'm trying to upload 2(two) images on firebase with captions but it only uploads the first successfully then the field for 2nd image box (nimagetrail2) copies the bitmap on the 1st image box (nimagetrial) on the database. Can someone help me fix this so that each image gets its own bitmap?

I only get a java.io.FileNotFoundException: No such file or directory exception. Earlier I tried saving it with an Success-Listener as it's shown here: https://stackoverflow.com/a/50743192/6274419. But that also hadn't worked because the function doesn't exist in the newer Firebase version.
In general I want to display a profile picture and the username which are saved to Firebase and retrieved on next application startup.
Thanks in Advance!
It takes some time to upload the image in firebase. So you can only retrieve the image when it is completely saved in database. Please call the loadUserData() method in OnSuccess and let me know if it works.
private void uploadToFirebase() {
//Select destination filename, folder
profileimageRef = FirebaseStorage.getInstance().getReference("profilepictures/" + System.currentTimeMillis() + ".jpg");
Log.wtf("ImageURL", profileimageRef.toString());
//Upload image
if(uriProfileImage != null)
{
//Show progressbar
progressBar.setVisibility(View.VISIBLE);
profileimageRef.putFile(uriProfileImage).addOnCompleteListener(new OnCompleteListener<UploadTask.TaskSnapshot>() {
#Override
public void onComplete(#NonNull Task<UploadTask.TaskSnapshot> task) {
//Hide progressbar
progressBar.setVisibility(View.GONE);
//Check if was successful
if(task.isSuccessful())
{
//Set profile image url
profileimageurl = task.getResult().toString();
loadUserData();
Log.wtf("ImageURL2", profileimageurl);
}else
{
Toast.makeText(ProfileActivity.this, task.getException().getLocalizedMessage() , Toast.LENGTH_SHORT).show();
}
}
});
Solved it now by using another structure/method for retrieving the url with a UploadTask:
private void uploadToFirebase() {
FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReference();
//Select destination filename, folder
final StorageReference profileimageRef = storageRef.child("profilepictures/" + System.currentTimeMillis() + ".jpg");
UploadTask uploadTask = profileimageRef.putFile(uriProfileImage);
Log.wtf("ImageURL", profileimageRef.toString());
//Upload image
if(uriProfileImage != null)
{
//Show progressbar
progressBar.setVisibility(View.VISIBLE);
Task<Uri> uriTask = uploadTask.continueWithTask(new Continuation<UploadTask.TaskSnapshot, Task<Uri>>() {
#Override
public Task<Uri> then(#NonNull Task<UploadTask.TaskSnapshot> task) throws Exception {
if (!task.isSuccessful())
{
throw task.getException();
}
return profileimageRef.getDownloadUrl();
}
}).addOnCompleteListener(new OnCompleteListener<Uri>() {
#Override
public void onComplete(#NonNull Task<Uri> task) {
progressBar.setVisibility(View.GONE);
if(task.isSuccessful()) {
profileimageurl = task.getResult().toString();
}
}
});
}
}

Retrieve stored image from Firebase Storage

I am trying to store and retrieve image by using Firebase. It is okay when storing an image, but I can't show it in an ImageView. It doesn't give an error so I can't understand where is the mistake.
public class MainActivity extends AppCompatActivity {
private Button btnSelectImage;
private ImageView mImageView;
private StorageReference mStorage;
private static final int CAMERA_REQUEST_CODE = 1 ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
btnSelectImage = (Button) findViewById(R.id.btn_image);
mImageView = (ImageView) findViewById(R.id.imageView);
//Get instance
mStorage = FirebaseStorage.getInstance().getReference();
btnSelectImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, CAMERA_REQUEST_CODE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==CAMERA_REQUEST_CODE && resultCode==RESULT_OK){
Uri uri = data.getData();
StorageReference filePath = mStorage.child("CameraPhotos").child(uri.getLastPathSegment());
filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
#Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
//Show image
Uri downloadUri = taskSnapshot.getDownloadUrl();
Picasso.with(MainActivity.this).load(downloadUri).into(mImageView);
Toast.makeText(MainActivity.this,"Upload Done",Toast.LENGTH_SHORT).show();
Log.v("Test","image load");
}
});
}
}
}
Also give permissions
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
Here is my Firebase Storage Rules
service firebase.storage {
match /b/fir-app-ce89f.appspot.com/o {
match /{allPaths=**} {
allow read, write: if true;
}
}
}
Here is my Activity Layout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.yusuf.firebaseapp.MainActivity">
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Select Image"
android:id="#+id/btn_image"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<ImageView
android:layout_width="400dp"
android:layout_height="350dp"
android:id="#+id/imageView"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
I suggest taking a look at FirebaseUI 0.6, which includes a Glide plugin that makes downloading an image from Firebase Storage as simple as:
// Reference to an image file in Firebase Storage
StorageReference storageReference = ...;
// ImageView in your Activity
ImageView imageView = ...;
// Load the image using Glide
Glide.with(this /* context */)
.using(new FirebaseImageLoader())
.load(storageReference)
.into(imageView);
I think it is easier if you use this way
StorageReference mImageRef =
FirebaseStorage.getInstance().getReference("image/test.jpg");
final long ONE_MEGABYTE = 1024 * 1024;
mImageRef.getBytes(ONE_MEGABYTE)
.addOnSuccessListener(new onSuccessListener<byte[]>() {
#Override
public void onSuccess(byte[] bytes) {
Bitmap bm = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
imageView.setMinimumHeight(dm.heightPixels);
imageView.setMinimumWidth(dm.widthPixels);
imageView.setImageBitmap(bm);
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception exception) {
// Handle any errors
}
});
private List<Upload> uploads;
Upload upload = uploads.get(position);
Glide.with(context).load(upload.getUrl()).into(holder.imageView);

i can't log in and get information if facebook app installed on android

I have following problem with facebook app.
I have a simple application 'myapp' where you find a simple button 'log in to facebook'
It displays a pop-up where you can type your email/password to log in.
After that, button changes his text to 'log out'
This code works fine if the user does not have facebook app installed on his phone. However,it does not work if user has facebook app on his phone.
I did not find the root cause for this problem because the code works fine if there is no facebook app installed on the phone
Below is the source code:
public class Facebook extends FragmentActivity {
private LoginButton loginBtn;
private TextView username;
private UiLifecycleHelper uiHelper;
Button post;
Bitmap bitmap=null;
URL imageURL=null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
uiHelper = new UiLifecycleHelper(this, statusCallback);
uiHelper.onCreate(savedInstanceState);
setContentView(R.layout.activity_facebook);
username = (TextView) findViewById(R.id.username);
loginBtn = (LoginButton) findViewById(R.id.fb_login_button);
post = (Button)findViewById(R.id.button1);
post.setVisibility(View.INVISIBLE);
post.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
postStatusUpdate(arg0);
}
});
loginBtn.setReadPermissions(Arrays.asList("email"));
loginBtn.setUserInfoChangedCallback(new UserInfoChangedCallback() {
#Override
public void onUserInfoFetched(GraphUser user) {
if (user != null) {
username.setText("You are currently logged in as " + user.getName());
String userID=user.getId();
} else {
username.setText("You are not logged in.");
}
}
});
}
private Session.StatusCallback statusCallback = new Session.StatusCallback() {
#Override
public void call(Session session, SessionState state,
Exception exception) {
if (state.isOpened()) {
post.setVisibility(post.VISIBLE);
Toast.makeText(getApplicationContext(), session.getAccessToken(), Toast.LENGTH_LONG).show();
Log.d("MainActivity", "Facebook session opened.");
} else if (state.isClosed()) {
post.setVisibility(post.INVISIBLE);
Log.d("MainActivity", "Facebook session closed.");
}
}
};
#Override
public void onResume() {
super.onResume();
uiHelper.onResume();
}
#Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
#Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
#Override
