Different versions of apk cover installation.
There are usually several possible reasons for this problem. According to the query, I love learning network display.

1. Version number problem: The version number of the new version is lower or the same as the old version, which makes it impossible to overwrite the old version.

2. Application signature problem: The application signature of the new version is different from that of the old version, so the old version cannot be overwritten.

3. Installation path problem: The installation path of the new version is different from that of the old version, so the old version cannot be overwritten.

4. Solution: Confirm the version number: Confirm that the version number of the new version is higher than the old version, and choose to overwrite the old version when installing. If the version number is the same, you can try to modify the version number and reinstall.

5. Use the same application signature: When developing a new version of the application, you need to use the same application signature to sign the APK file, so as to overwrite the old version when installing.

6. Specify the installation path: When installing a new version of the application, you can specify that the installation path is the same as the old version to overwrite the old version. In short, when installing different versions of the same application, make sure that the version number, application signature and installation path are consistent or appropriate with the old version to avoid problems.
