(sorry my english is very poor)
I develop an android app.
I want to download/upload images for my user. i use Retrofit and Picasso on my android app and on my local server i use Symfony. when creating user on my app, i store user's info on MYSQL DABASE with apache and i want to store user's profile picture on a directory like C:/wamp/www/My_app/mobil/photo/user_id/. Now my first question is i don't nkow how to send picture from android app to this folder.
And the second problem is i have tried to download some pictures from apache to android app using Picasso library. i use this cod :
Target target = new Target() {
#Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
user.setPhoto(HelpLoader.getBitmapAsByteArray(bitmap));
Log.e("PICTURE ok", "********************");
}
#Override
public void onBitmapFailed(Exception e, Drawable errorDrawable) {
Log.e("PICTURE FAIL", e.getMessage());
}
#Override
public void onPrepareLoad(Drawable placeHolderDrawable) {}
};
String url = "http://192.168.8.100/My_app/mobil/photo/" + user.getId() + "/profil.jpg";
Picasso.get().load(url).into(target);
i get a 403 Error and when i test the url with a browser apache show this error
Forbidden
You don't have permission to access /My_app/mobil/photo/2/profil.jpg"
but when i try simply to access to the folder /My_app/mobil/photo/2/, i don't have this error.
please help me.
i use :
- apache 2.4.23
- Symfony 3
- Retrofit 2 for send user's informations
- Picasso for the pictures
I am using the Salesforce SDK (4.1.x) in a native Android app. I use the RestClient.sendAsync method to post my form data to a custom object. That part is working fine. Now I need to upload and attach a photo that was taken by the mobile user. I see that RestClient has an uploadFile method. Is this the correct method? If so then how do I connect the uploaded file to the custom form data?
Ok. I figured this out. First, create the parent object (the main form data) using the following.
request = RestRequest.getRequestForCreate(apiVersion, objectType, fields);
client.sendAsync(restRequest, new RestClient.AsyncRequestCallback() {...
In the onSuccess method you will get the id of the new object from the response. There are plenty of examples that show how to get the JSON object and the id. Armed with this parentId we can now create the attachment. The code looks something like this.
private void postImageAsAttachment(String parentId, String title) {
Map<String, Object> fields = new HashMap<String, Object>();
fields.put("Name", title);
fields.put("ParentId", parentId);
fields.put("Body", ImageHelper.getBase64FromImage(mCurrentPhotoPath));
RestRequest request = null;
try {
request = RestRequest.getRequestForCreate(apiVersion, "Attachment", fields);
} catch (Exception ex) {
Log.d(TAG, "sendRequest: ", ex);
Toast.makeText(MainActivity.this, "The file upload failed: " + ex.toString(), Toast.LENGTH_LONG).show();
}
client.sendAsync(request, new RestClient.AsyncRequestCallback() {...
I'm using a simple class called ImageHelper that simply loads the image file, performs image compression (if necessary), and base64 encodes the image data. The result is that an "Attachment" object is created as a child of the parent object.
I hope this helps the next person.
I have an image on a server stored in a file (not db). I want to display this image in a layout view in Android Studio. I am using Web API2 and retrofit to exchange data.
Using retrofit, I know I need to send the file encapsulated in a class. I am not aware of what type to create? (Byte array?) and how retrofit on the android side would convert this type. I have tried to use byte[] on boths side however retrofit was not able to read the byte[] from Json.
Would anyone be able to guide me on how I would go about transferring this jpeg image? Thanks!
I've recently implemented it.
This is the method in my api.
[HttpPost]
public IHttpActionResult Upload()
{
var httpRequest = HttpContext.Current.Request;
if (httpRequest.Files.Count > 0)
{
foreach (string file in httpRequest.Files)
{
var postedFile = httpRequest.Files[file];
// Do something with file.
}
else
{
// No files.
}
}
The class you are looking for is retrofit's TypedFile class.
This is my implementation.
RestAdapter restAdapter = new RestAdapter.Builder().setEndpoint("baseurl").build();
ApiTaqueria api = restAdapter.create(ApiTaqueria.class);
TypedFile foto = new TypedFile("multipart/form-data", new File("path"));
api.subirLogoTaqueria(foto, new Callback<Taqueria>() {
#Override
public void success(Taqueria result, Response response) {
// Do something.
}
#Override
public void failure(RetrofitError retrofitError) {
// Do something.
}
});
In the retrofit interface.
#Multipart
#POST("/api/Photo/Upload")
public void subirLogoTaqueria(#Part("foto") TypedFile foto, Callback<Taqueria> callback);
Happy coding.
I am trying to load image from my S3 Bucket in my android application. My images are private so I won't be having any specific link for each image.
I'm using link generator,
s3Client.generatePresignedUrl(Constants.S3_BUCKET_NAME, key, expiration);
It generates a URL with let's say 1 hour or 2 min expiration.
Now I have problem in loading the url. I tried loading it by using picasso ,
Picasso.with(context).load(url.toString()).resize(30,38).into(holder.photo);
but it's not quite seems to be working. When I tried that link on browser I got following error
<Code>NoSuchKey</Code>
<Message>The specified key does not exist.</Message>
Try to attach error listener to Picasso and see what's going on. Also read logcat. Print URL which you pass to Picasso, does it correct?
Picasso.Builder builder = new Picasso.Builder(getApplicationContext());
builder.listener(new Picasso.Listener() {
#Override
public void onImageLoadFailed(Picasso arg0, String err) {
Log.e("Picasso Error", "Errored " + err);
}
});
builder.loggingEnabled(true);
Picasso pic = builder.build();
pic.load("image.jpg").into(iv);
I am sagar, i am trying to implement the Parse Push-Notification in android using REST API (Service), and i am almost got success in implement the Push-Notification in Xamarin-Android using REST API. But i got stuck with one part in sending the Data into REST service. I trying to pass the ParseObject in service, but the in parse table there is a need of Object,(). I have tried to pass the ParseObject as below:
JsonConvert.SerializeObject(ParseUser.CurrentUser)
It convert ParseObject into array and array is not accepted in table and ,i got failed to save it in table. because there i a need of object.
I need solution or suggestion from developer guys. Yours help will be appreciated. I am trying the below code to achieve the result.
public static void RegisterPush(string regristrationId)
{
if (regristrationId != null) {
string appID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string restID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string masterID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
try {
var client = new RestClient ("https://api.parse.com");
var request = new RestRequest ("1/installations", RestSharp.Method.POST);
request.AddHeader ("Accept", "application/json");
request.AddHeader ("X-Parse-Application-Id", appID);
request.AddHeader ("X-Parse-REST-API-Key", restID);
request.Credentials = new NetworkCredential (appID, masterID);
request.Parameters.Clear ();
Console.Error.WriteLine ("ParseUser.CurrentUser-->"+ (ParseObject) ParseUser.CurrentUser);
//JsonConvert.SerializeObject(ParseUser.CurrentUser)
string strJSONContent = "{\"user\" :"+ JsonConvert.SerializeObject(ParseUser.CurrentUser)+",\"owner\":\"" + ParseUser.CurrentUser.ObjectId + "\",\"deviceType\":\"android\",\"GCMSenderId\":\"1234567890\",\"appName\":\"abcdefgh\",\"pushType\":\"gcm\",\"deviceToken\":\"" + regristrationId + "\"}";
Console.Error.WriteLine("json string-->"+ strJSONContent);
request.AddParameter ("application/json", strJSONContent, ParameterType.RequestBody);
client.ExecuteAsync (request, response => {
Console.Error.WriteLine ("response for android parse installation-->" + response.Content);
});
} catch (Exception ex) {
Console.WriteLine (ex.Message);
}
}
}`

I found the solution in , parse xamarin docs, in one query , the way is simple, but i little bit hard to found out.
The issue is with the data passing in json format in REST, to pass any pointer using REST API, use as below.
The solution is as below:
`{
"user":{
"__type":"Pointer",
"className":"_User",
"objectId":"qYvzFzGAzc"
},
"owner":"qYvzFzGAzc",
"deviceType":"android",
"GCMSenderId":"123456789",
"appName":"NiceApp",
"pushType":"gcm",
"deviceToken":"APA91bFeM10jdrCS6fHqGGSkON17UjEJEfvJEmGpRM-d6hq3hQgDxKHbyrqAIxMnEGgbLEZf0E9AllHxiQQQCdEFiNMF1_A8q0n9tGpBE5NKhvS2ZGJ9PZ7585puWqz_1Z1EjSjOvgZ1LQo708DeL2KzA7EFJmdPAA"
}`
It looks like your column user is set up wrong. It should show as a Pointer<_User> not Pointer
If you load this class in your Data Browser, is the "user" key defined as a string, or a Pointer <_User>
This error seems to indicate that this is a string column, which is why the Parse.User object is not being accepted as a valid value. You might have tried setting a string on this key before, which in turn type-locked the "user" key as a string column.
Found it on the examples given on this page - https://www.parse.com/docs/rest
Have you check your REST API connection while passing ParseObject?
Because your error says:
Error:{"code":111,"error":"invalid type for key user, expected *_User, but got array"}
Here "code":111This error code comes when server refuse for connection
