how to (integrate)call post API with 2 parameters and 1 PDF file in android java

How to attach PDF file to post API with two parameter? I am using Fast android networking library.
I am able to call API but I when user touched button my API called in my API have three parameters like this:
message = "Test"
receiver_Email = "#gmail.com"
File = text.PDF;
Sy API allows only PDF form met with message and email. I am using Fast android networking library. I try to call API but I am not able to do it.
I also looked at some examples but it couldn't help me out.

just call this method from your onCreate this is the easy way to call API with file and parameter I hope it helps you
//method used to call API to send email
enter code here
#RequiresApi(API = Build.VERSION_CODES.LOLLIPOP_MR1)
public void call_Api()
{
final String key = "file";
final File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), "/test.pdf");
AndroidNetworking.initialize(this);
AndroidNetworking.upload("your API")
.setPriority(Priority.HIGH)
.addMultipartParameter("message", "test")
.addMultipartParameter("receiverEmail","testrg0017#gmail.com")
.addMultipartFile(key, file)
.setPriority(Priority.HIGH)
.build()
.getAsJSONObject(new JSONObjectRequestListener()
{
#Override
public void onResponse(JSONObject response)
{
Log.d("res ",response.toString());
if(file.exists())
{
Toast.makeText(PdfGeneration.this, "API call successfully",
Toast.LENGTH_SHORT).show();
}
}
#Override
public void onError(ANError anError)
{
anError.printStackTrace();
Log.d("res12 ",anError.toString());
if(!file.exists())
{
Toast.makeText(PdfGeneration.this, "file not available",
Toast.LENGTH_SHORT).show();
}
}
});
}

Faced an Issue related to Firebase Cloud Firestore

I was trying to store data to Firebase Cloud Firestore but after running my app it showed this error in the log.
[Firestore]: Write failed at Backpaper Registration/WSjZoirLf8WRBuGCVbUZ: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}
This is the part of my code.
fb=FirebaseFirestore.getInstance();
map=new HashMap<String>();
map.put("Name of Department",txtDepartment);
map.put("Name of Student",txtStudentName);
map.put("Registration No",txtRegNo);
map.put("CGPA in Previous Semester",txtCgpa);
map.put("Phone",txtPhoneNo);
map.put("Email",txtEMail);
map.put("Subject 1",txtSubject1);
map.put("Subject 2",txtSubject2);
map.put("Subject 3",txtSubject3);
map.put("Subject 4",txtSubject4);
map.put("Subject 5",txtSubject5);
map.put("Payment Details(Rs.)",txtPaymentDetails);
map.put("Payment Date",txtPaymentDate);
fb.collection("Backpaper Registration").add(map).addOnCompleteListener(new OnCompleteListener<DocumentReference>() {
#Override
public void onComplete(#NonNull Task<DocumentReference> task) {
if(task.isSuccessful()){
Toast.makeText(Backpaper.this, "Registration Successful", Toast.LENGTH_SHORT).show();
startActivity(new Intent(Backpaper.this,Academic.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP));
finish();
}
}
}).addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Toast.makeText(Backpaper.this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
});
Can somebody help me?

You should check out the Rules on Firebase
Change allow read, write: if false; to true;
Nots:
It is not advised to choose this solution because it makes the
database unsafe.
Only use this for testing purposes.

You need the Firebase rules setting at Firebase console.
If you had signed into project, the rules setting may like :
// Allow read/write access on all documents to any user signed in to the application
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if request.auth.uid != null;
}
}
}
If you just demo the function, you call setting the rules:
// Allow read/write access to all users under any conditions
// Warning: **NEVER** use this rule set in production; it allows
// anyone to overwrite your entire database.
service cloud.firestore {
match /databases/{database}/documents {
match /{document=**} {
allow read, write: if true;
}
}
}
The more officially document you can found here.
https://firebase.google.com/docs/firestore/security/get-started

It could be because, you have not given the read & write permission to firebase.
Change your Firebase Database to test mode.
1. Go to your firebase database console
2. Go to Rules
3. Start in test mode
This will change allow read, write: true
This turn off the database security but for testing purpose it is advised

Google Play Games Services: Writing saved games

Due to the recent changes in the Google Play Games Service API I'm forced to replace all the deprecated code in my Android app. I'm following the Google guide in https://developers.google.com/games/services/android/savedgames and it's not clear for me how to pass the snapshot to this function that writes the data to be saved.
private Task writeSnapshot(Snapshot snapshot, byte[] data, Bitmap coverImage, String desc) {
// Set the data payload for the snapshot
snapshot.getSnapshotContents().writeBytes(data);
// Create the change operation
SnapshotMetadataChange metadataChange = new SnapshotMetadataChange.Builder()
.setCoverImage(coverImage)
.setDescription(desc)
.build();
SnapshotsClient snapshotsClient =
Games.getSnapshotsClient(this, GoogleSignIn.getLastSignedInAccount(this));
// Commit the operation
return snapshotsClient.commitAndClose(snapshot, metadataChange);
}
Can you help me? I think an example of use of this function should be added to the documentation to make everything clearer and to help developers who need to learn this from scratch.

Ok, I realized how to do it. Basically, when you open the snapshot client, you must use continueWith and obtain the snapshot from the task.
Considering you have a proper cover image and description and a Google account where you signed in
mAccount = GoogleSignIn.getLastSignedInAccount(activity);
this is the code:
SnapshotsClient snapshotsClient = Games.getSnapshotsClient(activity, mAccount);
int conflictResolutionPolicy = SnapshotsClient.RESOLUTION_POLICY_MOST_RECENTLY_MODIFIED;
snapshotsClient.open(getSaveFileName(), true, conflictResolutionPolicy)
.addOnFailureListener(new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
Log.e(TAG, "Error", e);
}
}).continueWith(new Continuation<SnapshotsClient.DataOrConflict<Snapshot>, byte[]>() {
#Override
public byte[] then(#NonNull Task<SnapshotsClient.DataOrConflict<Snapshot>> task)
throws Exception {
Snapshot snapshot = task.getResult().getData();
snapshot.getSnapshotContents().writeBytes(getSaveGameData());
SnapshotMetadataChange metadataChange = new SnapshotMetadataChange.Builder()
.setCoverImage(coverImage)
.setDescription(desc)
.build();
SnapshotsClient snapshotsClient = Games.getSnapshotsClient(activity, mAccount);
snapshotsClient.commitAndClose(snapshot, metadataChange);
return null;
}
});

How to rotate mp4 files?

I have a mp4 file(already recorded) and want to change the rotation(including meta data) of the video. There is a way to do this using Hex Editor where in you find the track header(tkhdr) and replace the rotation matrix with the required rotation.
I know this can be done using ffmpeg library but I do not want to use the library instead I want to do this in Android using JAVA. Let me know if anyone has done this before.
Thanks
Ravi
Reference link

This library may help you: https://github.com/MasayukiSuda/Mp4Composer-android
This library generates an Mp4 movie using Android MediaCodec API and can rotate Mp4.
StackOverflow reference: https://stackoverflow.com/a/19392712/8572503
It's API is fluent and easy :
new Mp4Composer(sourceFile, destinationFile)
.rotation(Rotation.ROTATION_90)
.size(1280,720) //720P
.fillMode(FillMode.PRESERVE_ASPECT_FIT)
.listener(new Mp4Composer.Listener() {
#Override
public void onProgress(double progress) {
Log.d(TAG, "onProgress = " + progress);
//or show in notification
}
#Override
public void onCompleted() {
Log.v(TAG, "onCompleted() : Destination → "+ destinationFile);
}
#Override
public void onCanceled() {
Log.d(TAG, "onCanceled");
}
#Override
public void onFailed(Exception exception) {
Log.wtf(TAG, "onFailed()", exception);
}
})
.start();
You can also see this transcoder has written in pure Java: https://github.com/ypresto/android-transcoder
[EDIT: From Comment]:
You can extract code from this: https://github.com/javadev/hexeditor to manually modify the hex.

Trying to upload an image from android app to cloud using kinvey

I'm trying to upload an image, saved in the internal memory of my phone, clicked by an android app to a cloud service, and am using Kinvey to do so. But I'm facing some problems with it.
Every time I run the code that contains the upload part, I encounter an exception. I'm uploading an image of ".png" type. Any conversion to blob is not a necessary process that is required, unlike that in Google Cloud Platform.
Here is my .java code -
`Client mKinveyClient = new Client.Builder(APP_KEY, SECRET_KEY, this.getApplicationContext()).build();
mKinveyClient.enableDebugLogging();
mKinveyClient.ping(new KinveyPingCallback() {
public void onFailure(Throwable t) {
Log.e(TAG, "Kinvey Ping Failed", t);
}
public void onSuccess(Boolean b) {
Log.d(TAG, "Kinvey Ping Success");
}
});
java.io.File file = new java.io.File(Environment.getExternalStorageDirectory().getPath() + "/Camera/" + "IMG_20161115_193353.jpg");
mKinveyClient.file().upload(file, new UploaderProgressListener() {
public void onSuccess(Void result) {
Log.i(TAG, "successfully upload file");
}
#Override
public void onSuccess(FileMetaData fileMetaData) {
Log.i(TAG, "successfully uploaded file");
}
#Override
public void onFailure(Throwable error) {
Log.e(TAG, "failed to upload file.", error);
}
#Override
public void progressChanged(MediaHttpUploader uploader) throws IOException {
Log.i(TAG, "upload progress: " + uploader.getUploadState()); // all updates to UI widgets need to be done on the UI thread
}
});`
Now, although the ping call is giving me a successful response, the upload part is giving me an error.
E/Activity file: failed to upload file.
com.kinvey.java.KinveyException:
REASON: No user is currently logged in.
I've searched a lot on this topic, on kinvey's discussion platform and here too. But I'm still stuck. I don't know where I'm going wrong or what I might be missing.
If anyone is out there who has successfully managed to upload images through kinvey then please help me out.

Any kind of Kinvey operations must be provided via a logged user.
You must sign up (or login) before you start to i/o any information.
mKinveyClient.user().create("username", "password", new KinveyUserCallback()) {
#Override
public void onFailure(Throwable t) {
CharSequence text = "Could not sign up.";
Toast.makeText(getApplicationContext(), text, Toast.LENGTH_SHORT).show();
}
#Override
public void onSuccess(User u) {
//here we go on uploading file
}
});
You can find more info about users here

Sharmistha,
Yes, every app action needs an active user context.
So you will need to login in the app and then upload the file.
Please take a look at the following:
