在Android应用程序中将图像上载到服务器
在我的应用程序中，我正在捕获图像并将其上载到服务器。捕获和上传部分在我的500万像素安卓设备上运行良好 但拍照时，该应用程序偶尔会崩溃。我们注意到如果有人拿了 图片设置为高百万像素，照片无法上传，应用程序崩溃 如何减少800万像素照片的大小，以便能够在不崩溃的情况下上传？ 我必须压缩捕获的图像吗。下面是我捕获图像的代码在Android应用程序中将图像上载到服务器,android,camera,Android,Camera,在我的应用程序中，我正在捕获图像并将其上载到服务器。捕获和上传部分在我的500万像素安卓设备上运行良好 但拍照时，该应用程序偶尔会崩溃。我们注意到如果有人拿了 图片设置为高百万像素，照片无法上传，应用程序崩溃 如何减少800万像素照片的大小，以便能够在不崩溃的情况下上传？ 我必须压缩捕获的图像吗。下面是我捕获图像的代码 ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE,fi
