Install Intent plugin in Phonegap 3.0

Hi, I am working on a Phonegap project in Android where among others I have a page with a button that will trigger a download process to sdcard/download/ and after that an installation process.

In this tip I will write my solution that works at the moment. There are probably better solutions, but I am still learning all these technologies and I am happy that at least works.

So, the first step would be to create a Java class in your project that extends CordovaPlugin class. I called it "InstallIntent.java". It is a very simple class, where all that matters is the "execute" method:

import java.io.File;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.PluginResult;
import org.json.JSONArray;

import android.content.Intent;
import android.net.Uri;
import android.os.Environment;
import android.util.Log;
import android.widget.Toast;

public class InstallIntent extends CordovaPlugin {

    @Override
    public boolean execute(String action, final JSONArray args, final CallbackContext callbackContext) {
        if (action.equals("install")) {
            cordova.getThreadPool().execute(new Runnable() {//
                @Override
                public void run() {
                    String apkPath = Environment.getExternalStorageDirectory().toString() + "/download/YourAPK.apk";
                    Intent install = new Intent(Intent.ACTION_VIEW); 
                    install.setDataAndType(Uri.fromFile(new File(apkPath)),"application/vnd.android.package-archive");
                    cordova.getActivity().startActivity(install);
                    Log.d("my tag", "after the install action");
                    //showToast("App cache is deleted.","short");
                }
            });
        callbackContext.sendPluginResult(new PluginResult(PluginResult.Status.OK));
        return true;
    } else {
            Log.e("PhoneGapLog", "CacheCleaner Plugin: Error: " +     PluginResult.Status.INVALID_ACTION);
            callbackContext.sendPluginResult(new     PluginResult(PluginResult.Status.INVALID_ACTION));
            return false;
        }
    }
}

The action in this case is called "install" and is important, as it will be called from Javascript.

In your Phonegap project in the particular assets/www/js folder create install-intent.js

cordova.define("cordova/plugin/installation", function (require, exports, module) {
    var exec = require("cordova/exec");
  module.exports = {
        install: function (win, fail) {
            exec(win, fail, "InstallIntent", "install", []); //InstallIntent is the name of the Java class and install is the method called from the front end side. 
        }
    };
});

In the manifest file I included the following permissions:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.RESTART_PACKAGES"/>

In your index.html include cordova.js, install-intent.js files and the file with your custom scripts, for example custom.js where you can call your install_intent like this:

var installation = cordova.require("cordova/plugin/installation");
installation.install(function() {
        console.log("PhoneGap Plugin: InstallIntent: callback success");
    },
    function() {
        console.log("PhoneGap Plugin: InstallIntent: callback error");
    }
);

In the end add the following line to your config.xml (the one under ProjectName\platforms\android\res\xml)

<feature name="InstallIntent">
    <param name="android-package" value="com.your.package.name.InstallIntent" />
</feature>

Again, this plugin will trigger an installation process of .apk file from external directory / download. I hope it helps anybody.

thanks for this! any idea how to get the apk to launch after it gets downloaded and installed?

Hi, I think It should automatically ask for the opening of the file, and so installing the .apk. I gave up at the Phonegap project and made everything from scratch, so that would not be for much help for you. Florin

Just to respond, it actually installs the app and then the window disappears completely, it's not like when u normally install an app where it has an "open this app" button. Not too big of a deal I was just curious. Thanks again :)
