Question

我想在我的服务器上获取apk，在android上安装apk后

但是当我安装apk时，它会显示ActivityNotFoundException。

或许，许可问题？

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

感谢请给我建议

我猜您在将包名设置为Intent时会出现拼写错误。它应该是“application / vnd.android.pa ck age-archive”。所以整行都是：

webIntent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");

这就是为什么你得到ActivityNotFoundException，因为你提供错误的包裹，并且找不到合适的Activity。

我使用DownloadManager.ACTION_DOWNLOAD_COMPLETE但发生ActivityNotFoundException
