Android Auto Installation Of Apks

I have a webview which basically is capable of intercepting all sorts of links, video, apks, hrefs. Now, what I want is once I download an APK from a url, that it'll be auto instal

Solution 1:

To download a file without the browser do sth. like this:

Stringapkurl="http://your.url.apk";
InputStream is;
try {
    URLurl=newURL(apkurl);
    HttpURLConnectioncon= (HttpURLConnection) url.openConnection();
    con.setRequestMethod("GET");
    con.setDoOutput(true);
    con.connect();
    is = con.getInputStream();
} catch (SSLException e) {
    // HTTPS can end in SSLException "Not trusted server certificate"
}

// Path and File where to download the APKStringpath= Environment.getExternalStorageDirectory() + "/download/";
StringfileName= apkurl.substring(apkurl.lastIndexOf('/') + 1);
Filedir=newFile(path);
dir.mkdirs(); // creates the download directory if not existFileoutputFile=newFile(dir, fileName);
FileOutputStreamfos=newFileOutputStream(outputFile);

// Save file from URL to download directory on external storagebyte[] buffer = newbyte[1024];
intlen=0;
while ((len = is.read(buffer)) != -1) {
    fos.write(buffer, 0, len);
}
fos.close();
is.close();

// finally, install the downloaded file
install(path + fileName);

Solution 2:

You can temp. download it to an sd card, install it with the package manager and then remove it again.

protectedvoidinstall(String fileName) {
    Intent install = newIntent(Intent.ACTION_VIEW);
    install.setDataAndType(Uri.fromFile(newFile(fileName)),
            "application/vnd.android.package-archive");
    startActivity(install);
}

Solution 3:

Due to Android security model it is not possible to install Apk file automatically.

Solution 4:

why not trying with a download manage and a broadcast receiver that would intercept when download is finished? Download manager works for ANDROID 2.3+ though

Example here:

myWebView.setWebViewClient(newWebViewClient() {
    @OverridepublicvoidonReceivedError(WebView view, int errorCode,
        String description, String failingUrl) {
            Log.d("WEB_VIEW_TEST", "error code:" + errorCode + " - " + description);
    }

    @OverridepublicbooleanshouldOverrideUrlLoading(WebView view, String url) {
            // handle different requests for different type of files// this example handles downloads requests for .apk and .mp3 files// everything else the webview can handle normallyif (url.endsWith(".apk")) {
                Uri source = Uri.parse(url);
                // Make a new request pointing to the .apk urlDownloadManager.Request request = newDownloadManager.Request(source);
                // appears the same in Notification bar while downloading
                request.setDescription("Description for the DownloadManager Bar");
                request.setTitle("YourApp.apk");
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                    request.allowScanningByMediaScanner();
                    request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
                }
                // save the file in the "Downloads" folder of SDCARD
                request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "SmartPigs.apk");
                // get download service and enqueue fileDownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
                manager.enqueue(request);
            }
            elseif(url.endsWith(".mp3")) {
                // if the link points to an .mp3 resource do something else
            }
            // if there is a link to anything else than .apk or .mp3 load the URL in the webviewelse view.loadUrl(url);
            returntrue;                
    }
});

Broadcast receiver to intercept when download has finished

privateBroadcastReceiveronDownloadComplete=newBroadcastReceiver() {
    @OverridepublicvoidonReceive(Context context, Intent intent) {
        Stringaction= intent.getAction();
        if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
            // toast here - download complete 
        }
    }
};

remember to recister recevier in the main activity like this:

registerReceiver(onDownloadComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
