我需要根据服务器的最新版本卸载并重新安装 apk 文件。当我不在 Google Play 中更新我的应用程序时，如何卸载并重新安装该应用程序？我的卸载代码：

public void UnInstallApplication(String packageName)// Passing com.example.homelauncher as package name.
    {

        Uri packageURI = Uri.parse(packageName.toString());
        Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
        uninstallIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(uninstallIntent); 
    }

我收到以下错误：

谁能告诉我如何在不使用 Google Play 的情况下做到这一点？

你的形成URI不正确。有关相关问题，请参阅此 SO 帖子（几乎是重复的）。我已经复制了下面的相关细节：基本上你需要使用下面的代码来构造URIIntent 方法才能工作。

Intent intent = new Intent(Intent.ACTION_DELETE, Uri.fromParts("package",
getPackageManager().getPackageArchiveInfo(apkUri.getPath(), 0).packageName,null));
startActivity(intent);

如果您的设备是 rootet，您可以使用在 Android Linux shell 中执行的 adb 命令卸载 apk。

String command = "pm uninstall com.my.first.program ";
