我正在为Android电视创建一个应用程序，其中Apk下载其更新并进行调整，但我尝试了两种情况
String command;
command = "adb install -r " + filename;
Process proc = Runtime.getRuntime().exec(new String[] { "su", "-c", command });
proc.waitFor();
这也是：
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive");
startActivity(intent);
首先成功下载第一个案例文件并在完成后在后台安装它将成功运行命令并使用接收器重新启动，但它没有更新应用程序它显示旧版本!!
在第二种情况下，它询问用户安装或取消，有时（用户确实找不到鼠标或遥控器）电视，所以我也不想显示此提示。 ！ 可以有人请推荐我更好的选项安装没有任何点击它可能背景或前景无关紧要。 请帮忙 ！！谢谢

你需要扎根，但这里是我在6.0上使用的一些代码来执行此操作。我没有在之前或更新版本上测试它，并且它使用Android私有API，因此它可能随时死亡。此外，如果应用程序自行更新，该应用程序将被强制关闭，因此您最好在第二个应用程序中运行此应用程序，以便在更新时重新启动您的活动。

我相信您需要的权限是<uses-permission android:name="android.permission.INSTALL_PACKAGES" />，但很难分辨，因为这是一个安装了许多权限的自助服务终端模式应用，因为无法正确更新列表。
