每当我尝试在我的三星Galaxy S3上的Google Play商店下载一个应用程序时，它会一直说"包文件无效" ，不会让我下载任何内容。消息也有一个三角形！内部。
Whenever I try to download an app in the Google Play Store on my Samsung Galaxy S3, it keeps saying "package file invalid" and won't let me download anything. The message also has a triangle with a ! inside it.
Try downloading via WIFI.
I had this issue recently, same phone. Tried a few times; both on PC and on the device itself each failed. I realized WiFi was off (mobile data only). I turned WiFi on and the file downloaded first go.
This worked for me.
