PhoneGap Kamera-API für Android - Uncaught Exception

Ich versuche zu laufen, die Kamera-API mithilfe von Telefon-Lücke in Android, und ich habe mich in alle Art von Fragen.

Ich nur kopiert phonegap Kamera Beispiel.

Ich erhalte die folgende Fehlermeldung

07-12 18:18:00.706: E/Web Console(17837): Uncaught TypeError: Cannot read property 'SAVEDPHOTOALBUM' of undefined at file:///android_asset/www/index.html:98

07-12 18:17:59.456: E/Web Console(17837): Uncaught ReferenceError: Camera is not defined at file:///android_asset/www/index.html:67

Ich habe versucht, alle anderen Ziel-Typ. Es dint Arbeit

destinationType: destinationType.FILE_URI
destinationType: Camera.DestinationType.FILE_URI
destinationType: destinationType.DATA_URL

Außerdem habe ich noch die Berechtigung für die Kamera und hardware-Kamera-Berechtigung. Aber es scheiterte

Hier ist die folgende

  • Es klingt wie Sie sind nicht immer das deviceready-Ereignis. Sollten Sie eine Konsole.log in onDeviceReady, um zu sehen, wenn es aufgerufen wird.
