App PhoneGap Crash quando si scatta una nuova foto con il plug-in della fotocamera

Question

Sto sviluppando un'app mobile con cordova/PhoneGap e ho installato il plug-in Camera. Sono in grado di aprire la fotocamera e fare clic sull'immagine, ma dopo quell'app si blocca. qui è il registro incidente:

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=34, result=-1, data=null} to activity {com.phonegap.helloworld/com.phonegap.helloworld.CordovaApp}: java.lang.IllegalArgumentException: filename cannot be null

codice che ho usato per aprire la fotocamera è:

var pictureSource; // picture source 
var destinationType; // sets the format of returned value 
document.addEventListener("deviceready", onDeviceReady, false); 

function onDeviceReady() { 
    // alert("ready-----") 
    pictureSource = navigator.camera.PictureSourceType; 
    destinationType = navigator.camera.DestinationType; 
} 

function capturePhoto() { 
    alert(navigator.camera); 
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, { 
    quality: 20, 
    destinationType: destinationType.FILE_URI, 
    targetWidth: 200, 
    targetHeight: 200, 
    saveToPhotoAlbum: true, 
    sourceType: pictureSource.CAMERA 
    }); 
} 

function onPhotoDataSuccess(imageURI) { 
    // alert("success--"); 
    var smallImage = document.getElementById('smallImage'); 
    smallImage.style.display = 'block'; 
    smallImage.src = imageURI; 
    // smallImage.src = "data:image/jpeg;base64," + imageData; 
} 

function onFail(message) { 
    alert('Failed because: ' + message); 
} 

Il bug è già connesso Apache Cordova.

Aiuto !!!

Answer 1

si prega di modificare il tipo di destinazione:

destinationType: destinationType.FILE_URI 

a

destinationType: Camera.DestinationType.FILE_URI 

se richiesto come immagine Base64 codifica, poi cambiare tipo di destinazione come:

destinationType: Camera.DestinationType.DATA_URL 

anche assicurati di aver aggiunto l'autorizzazione di scrittura esterna di scrittura nel file manifest.

Answer 2

Provare a sostituire la funzione capturePhoto() con questo (questo codice sta lavorando dalla mia app):

function capturePhoto() { 
    var options = { 
     quality: 75, 
     destinationType: Camera.DestinationType.FILE_URI, 
     sourceType: Camera.PictureSourceType.CAMERA, 
     mediaType: Camera.MediaType.CAMERA, 
     encodingType: Camera.EncodingType.JPEG, 
     targetWidth: 200, 
     targetHeight: 200, 
     saveToPhotoAlbum: true 
    }; 
    navigator.camera.getPicture(onPhotoDataSuccess, onFail, options); 
} 

Answer 3

Il plugin sta passando un puntatore nullo per ExifInterface causando un'eccezione, che non è accaduto in plugin più vecchi.

Provare ad applicare la seguente correzione, inoltre è possibile segnalare il dispositivo Marca, Modello e versione Android pure?
