推荐答案

您是否直接在 .apk 文件中编辑了 AndroidManifest.xml?如果是这样，那将不起作用.

Did you edit the AndroidManifest.xml directly in the .apk file? If so, that won't work.

每个 Android .apk 都需要签名，如果它将安装在手机上，即使您不是通过市场安装.开发工具通过使用开发证书签名来解决此问题，但 .apk 仍被签名.

Every Android .apk needs to be signed if it is going to be installed on a phone, even if you're not installing through the Market. The development tools work round this by signing with a development certificate but the .apk is still signed.

它的一个用途是让设备可以判断 .apk 是否是已安装应用程序的有效升级，因为如果是，则证书将相同.

One use of this is so a device can tell if an .apk is a valid upgrade for an installed application, since if it is the Certificates will be the same.

因此，如果您对应用进行任何更改，则需要重新构建 .apk 以使其正确签名.

So if you make any changes to your app at all you'll need to rebuild the .apk so it gets signed properly.
