我正在使用 phonegap 从设备相机或图库中抓取图像。相机部分工作正常，但是当我单击调用galleryButton() 的按钮时，应用程序就会卡住。这是我正在使用的代码：

function cameraButton() {
    callLib(Camera.PictureSourceType.CAMERA);
}

function galleryButton() {
    callLib(Camera.PictureSourceType.PHOTOLIBRARY);
}

function callLib(sourceType) {
    navigator.camera.getPicture(onSuccess, onFail, {    quality: 50,
                                                        destinationType : Camera.DestinationType.DATA_URL, 
                                                        sourceType : sourceType, 
                                                        allowEdit : false,
                                                        encodingType: Camera.EncodingType.JPEG,
                                                        targetWidth: 512,
                                                        targetHeight: 512,
                                                        saveToPhotoAlbum: false } );
}

日志输出：

我有以下权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.CAMERA"/>

编辑 一切都很完美。galleryButton() 从未被调用 :P 我的错误。有人关闭这个问题。

这些可选参数仅用于自定义相机设置。allowEdit：假，encodingType：Camera.EncodingType.JPEG，targetWidth：512，targetHeight：512，

为 photolib 创建一个新函数，该函数将包含 quality : 40, destinationType : sourceType :
