Question

我正在使用Cordova和Worklight 6.3开发应用程序，使用camera.getPicture函数时遇到问题。

请查看下面的相机代码段。

var cameraOptions = {
    quality: 50,
    targetWidth: 720,
    targetHeight: 600,
    encodingType: Camera.EncodingType.JPEG,
    destinationType: Camera.DestinationType.DATA_URL,
    correctOrientation: true,
    sourceType: Camera.PictureSourceType.CAMERA
};

Android错误日志：

我关注ibm Fix但是同样的错误 https://www.ibm.com/support/knowledgecenter/SSHS8R_6.3.0/com.ibm.worklight.dev.doc/dev/t_android_cam_api_24.html

的AndroidManifest.xml

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

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true" >
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths" />

Answer 1

在default.xml中添加以下行

<preference name="applicationId" value="com.APPlol.test" /> 
// ID in widget is the value
<widget id="com.APPlol.test"></widget> // in config .xml

navigator.camera.getPicture在android中不起作用
