java - Android APK 无法安装在设备上

Question

//无法在我的手机上安装 apk，当我从 adb 推送应用程序时，它会抛出以下错误

我正在使用 mmm/root/android/system/packages/apps/Contacts/进行编译

我的疑问是，当我最近重新启动计算机时，已安装应用程序的输出目录从旧路径:/root/android/system/out/target/product/vision/system/app到新路径:/root/android/system/out/target/product/generic/system/app

我的所有其他应用程序都存在于旧路径中，当我从旧路径安装contacts.apk时，它会正确安装，并且在我重新启动计算机后，当我尝试从构建它的新路径安装时，它会给出我出现以下错误。我不明白这可能是什么环境问题？任何人都可以建议我可以做什么吗？

adb Push Contacts.apk/system/app/Contacts.apk

你在 build 之前忘记吃午饭了。这就是为什么它构建在 out/target/product/generic 而不是 out/target/product/vision 中。看来您的通用构建已设置为构建 odexed apk，这就是 apk 内没有 classes.dex 的原因。
