应用无法安装：INSTALL_PARSE_FAILED_NO_CERTIFICATES。

Question

11:45   Gradle build finished in 38 s 984 ms

11:45   Failed to commit install session 80875563 with command cmd package install-commit 80875563.

 Error: INSTALL_PARSE_FAILED_NO_CERTIFICATES: Package /data/app/vmdl80875563.tmp/0_app-release has no certificates at entry AndroidManifest.xml

11:45   Session 'app': Installation did not succeed.
                The application could not be installed: INSTALL_PARSE_FAILED_NO_CERTIFICATES
                Retry

我已经尝试过以下操作：

1. 使应用程序无效并重新启动。
2. 构建Bundle/APK。
3. 删除应用程序后在手机上安装APK并运行APK。
4. 增加版本代码和版本名称。

生成apk文件是有效的，但是使用apk文件安装并运行时出现问题。 可以通过以下步骤生成签名的Bundle或APK：进入工具→生成签名的Bundle或APK→选择现有项→下一步→勾选V1 Debug、Release→完成。 虽然这种方法能够生成apk文件，但是我的手机不能够安装该apk文件。

Answer 1

我的情况是我们的应用程序包名为com.a.b，并依赖于一个名为com.a.c的库，但同时该库还有演示应用程序com.a.c.d。
在删除com.a.c.d后，我的应用程序成功安装。

当我使用不可靠的USB连接电缆时，也会出现这个问题。
