I found out here that, I should use the below script to make it work, but I don't know where to put it in the script and I need help, I'm new to PhoneGap.
options.headers = {
Connection: "close"
}
options.chunkedMode = false;
Add true in as last param of Upload Function
upload(filePath, server, successCallback, errorCallback, options, true);
Try putting options.header inside uploadPicture() rather than putting it at start of your document.
function uploadPicture() {
......
......
if(server) {
// Specify transfer options
var options = new FileUploadOptions();
options.fileKey="file";
options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
options.mimeType="image/jpeg";
options.headers = {
Connection: "close"
}
options.chunkedMode = false;
// Transfer picture to server
var ft = new FileTransfer();
ft.upload(imageURI, server, success, failure, options, true);
}
}

I'm trying to implement the login action using the twitter acount in my cordova app.
I have found a script using Childbrowser.js file to do it but it's not supported anymore so that I am trying to do it using the inappBrowser plugin instead of the childbrowser.
I succeeded in opening the login interface but after the login it redirect me to a web page. How can I redirect to my html local page? can I get ignore the redirect url and just get the access token?
this is the code that I am using:

Actually there is error in your code you have to fix it:
the https://api.twitter.com/1/account/verify_credentials.json?skip_status=true' is no more used change it to 1.1.
also change the way you close your inappbrowser.
this code works for me try it:

I click the button and select a photo, it alerts "An error has occurred.Code = 2", how to solve this problem?
Thanks for help!
You will want to specify a full path to the upload.php file, example:
ft.upload(imageURI, "http://www.mydomain.com/upload.php", win, fail, options);

I don't know how to access specific camera on android phone, anyone who knows? thanks
There is now the ability to specify a camera in the latest specification with the facingMode property: http://www.w3.org/TR/mediacapture-streams/#idl-def-VideoFacingModeEnum
This property is an optional part of the MediaStreamConstraints object that is the first argument of the getUserMedia method.
Here's a simplified example from the spec:
var supports = navigator.mediaDevices.getSupportedConstraints();
if (!supports["facingMode"]) {
// Handle lack of browser support if necessary
}
var gotten = navigator.mediaDevices.getUserMedia({
video: {
facingMode: {exact: "environment"}
}
});
The value environment means the back camera of the device. Other values are user, left and right.
Note that support for this varies depending on the browser/browser version.
See function gotSources(sourceInfos) in the code below

Hi I think this works with you
<script>
var gum = mode =>
navigator.mediaDevices.getUserMedia({video: {facingMode: {exact: mode}}})
.then(stream => (video.srcObject = stream))
.catch(e => log(e));
var stop = () => video.srcObject && video.srcObject.getTracks().forEach(t => t.stop());
var log = msg => div.innerHTML += msg + "<br>";

well: part of this code is not mine.
QUESTION

I want to call image crop on #page2, so there is an upload button to upload the cropped image...
can anybody help me do that??
PhoneGap does not have built-in crop features. Some platforms (iPhone for sure) allows the user to crop the picture after taking it with the camera but before it would be returned to your JavaScript code if you pass the allowEdit = true parameter to getPicture. But you won't have control here from your script.
You'll have to implement the cropping feature yourself from JavaScript. It is easier then expected with the canvas tag of HTML5. You can find a pretty tutorial here.
I found the solution for this(it is too late but used for someone like me) but after taking image you need to pass the image path to the plugin(Native android) for croping.
put the following code in your image capture or pick image from gallery(in your index.html):
navigator.camera.getPicture(function(imageURI){
window.resolveLocalFileSystemURI(imageURI, function(fileEntry){
fileEntry.file(function(fileObj) {
var imagedata ="sample/new001.img";
// able to get the image location using phonegap
cropImage.createEvent(imagedata);
});
}, fail);
}, fail, { quality: 50,
destinationType: destinationType.NATIVE_URI,
sourceType: pictureSource.PHOTOLIBRARY
});
after that crop.image.js should be like (include this file name in your index.html)
var cropImage = {
createEvent: function(fileName) {
cordova.exec(
null, // success callback function
null, // error callback function
'CropImage', // mapped to our native Java class called "CropImage"
'GetImageName', // with this action name
[fileName]
);
}
}
Your java code is like
public class CropImage extends CordovaPlugin{
public final String ACTION_GET_IMAGE_NAME = "GetImageName";
Uri myUri;
#Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) {
// Log.e(TAG,"Inside Version plugin.");
boolean result = false;
if(action.equals(ACTION_GET_IMAGE_NAME)) {
try {
myUri = Uri.parse(args.getString(0));
cropCapturedImage(myUri);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
result = true;
}
return result;
}
public void cropCapturedImage(Uri picUri){
//call the standard crop action intent
Intent cropIntent = new Intent("com.android.camera.action.CROP");
//indicate image type and Uri of image
cropIntent.setDataAndType(picUri, "image/*");
//set crop properties
cropIntent.putExtra("crop", "true");
cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);
cropIntent.putExtra("outputX", 256);
cropIntent.putExtra("outputY", 256);
// for save the image in same location with same name.
File f = new File(Environment.getExternalStorageDirectory()+"your image location here");
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
cropIntent.putExtra("output", Uri.fromFile(f));
cropIntent.putExtra("return-data", false);
//start the activity - we handle returning in onActivityResult
this.cordova.startActivityForResult((CordovaPlugin) this,cropIntent, 2);
}
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
//Log.e("final", String.valueOf(requestCode));
/*if(requestCode == 2){
//Create an instance of bundle and get the returned data
Bundle extras = intent.getExtras();
//get the cropped bitmap from extras
Bitmap thePic = extras.getParcelable("data");
}*/
}
}
Don't forget to add this class in your CONFIG.XML and add the necessary permissions. Feel free to ask any doubts.
