在Intent.ACTION_PICK时，Gallery会抛出NullPointerException

标签： android android-intent

在我的应用中，我想从图库中选择一张图片：

Intent pickPhoto = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);

但有时候Android的画廊会停止。查看未过滤的日志我有以下错误（注意：我的代码中没有错误，系统抛出它）：

橙色：
