Android的 - 有结果编程安装应用程序 [英] Android - Install Application programmatically with result

问题描述

我是新来的Andr​​oid，我有其中包括在服务上的一些点服务需要安装一个新的apk（基本上是一个自动更新）的应用程序，目前安装像在$ C $完成ç娄不允许知道，当它完成或得到一个结果了它，我需要知道，为了执行驱动该结果的其他操作。

I am new to Android and I have an application which consists in a service and on some point the service needs to install a new .apk (basically an auto-update), currently the installation is done like in the code bellow which does not allow to know when it finishes or get a result out of it and I need to know that in order to perform other actions driven on that result.

File mFile = new File(Uri.parse(downloadedPackageUriString).getPath());
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
        .setDataAndType(Uri.fromFile(mFile), "application/vnd.android.package-archive")
        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
appContext.startActivity(promptInstall);

我想知道是否有这样做的一种方式？
谢谢你在前进。

I would like to know if there is a way of doing that? Thank you in advance.

推荐答案

的逻辑可能是：

1. 安装脚本


2. 等待5秒钟


3. 运行 appInstalledOrNot 功能


4. 如果没有安装，那么在1秒内再试

下面可能是code：

public void installApp(){
    File mFile = new File(Uri.parse(downloadedPackageUriString).getPath());
    Intent promptInstall = new Intent(Intent.ACTION_VIEW)
            .setDataAndType(Uri.fromFile(mFile), "application/vnd.android.package-archive")
            .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    appContext.startActivity(promptInstall);

    Thread t = new Thread(){
        public void run(){

            boolean installed = checkInstalled("vnd.android.package-archive");
            while(!installed)
            {
                System.out.println("Not Installed Yet..Waiting 1 Second");
                t.sleep(1000);
            }

            //Now it has been installed
            if(installed) {
                //This intent will help you to launch if the package is already installed
                Intent LaunchIntent = getPackageManager()
                    .getLaunchIntentForPackage("com.Ch.Example.pack");
                startActivity(LaunchIntent);

                System.out.println("App already installed on your phone");        
            }
            else {
                System.out.println("App is not installed on your phone");
            }
            }
    t.start();
}

private boolean checkInstalled(String uri) {
    PackageManager pm = getPackageManager();
    boolean app_installed = false;
    try {
        pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES);
        app_installed = true;
    }
    catch (PackageManager.NameNotFoundException e) {
        app_installed = false;
    }
    return app_installed ;
}
