Question

我一直在阅读很多并在互联网上搜索，我发现了类似的问题，但仍然没有答案。所以我会再试一次:)）

我正在开发一个带有phonegap 2.7的应用程序，我正在使用推荐的功能来上传图片。问题是某些用户在尝试选择图片时报告异常，而且应用程序崩溃了。

查看Google Play控制台，我可以看到此错误：

  java.lang.RuntimeException: Unable to resume activity 
  {com.xmile.events/com.xmile.events.MainActivity}: java.lang.RuntimeException: Failure

选择图像的功能就是这个：

function selectPicture() {
    pictureSource=navigator.camera.PictureSourceType;
    destinationType=navigator.camera.DestinationType;

    // Retrieve image file location from specified source
    navigator.camera.getPicture(
        onPhotoURISuccess, onFail, { quality: 25, 
        destinationType: destinationType.FILE_URI,
        sourceType: pictureSource.PHOTOLIBRARY });
}

所以我理解当用户选择一个图像然后回到主过程时会出现问题...不知何故它已经死了然后NPE出现了：'（更奇怪的是，它只发生在一些用户和我无法用手机重现它。

任何帮助都将受到高度赞赏！

我猜您正在尝试使用Android 4.1或4.2版。如果是这样的话，请参考这个答案： Phonegap : Upload picture crashes on Samsung mobile 4.1.2 but works fine on Google Nexus 4.3.0
