这是我使用的代码，它不适用于webview，但你可以轻松覆盖网址加载并应用此代码。底部的意图是你问题的答案。

/**

 * When started, will download latest version of AN APPLICATIONand launch an install
 * Is just a dialog
 * 
 * REQUIRES SDCARD

public class Main extends Activity {
ProgressDialog dlDialog;
String path = Environment.getExternalStorageDirectory()+ "/"; // Path to where you want to save the file
String inet = "http://www.google.com/test.apk"; // Internet path to the file
String cachedir = "";                                       
String filename = "TMC.apk";                                

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TextView webview = new TextView(this);
    setContentView(webview);

    File getcache = this.getCacheDir();
    cachedir = getcache.getAbsolutePath();

    dlDialog = new ProgressDialog(Main.this);
    dlDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
    dlDialog.setTitle("Downloadin");
    dlDialog.setMessage("Connecting");
    dlDialog.show();

    new Thread(new Runnable() {

        public void run() {

            String filePath = path;

            InputStream is = null;
            OutputStream os = null;
            URLConnection URLConn = null;

            try {
                URL fileUrl;
                byte[] buf;
                int ByteRead = 0;
                int ByteWritten = 0;
                fileUrl = new URL(inet);

                URLConn = fileUrl.openConnection();

                is = URLConn.getInputStream();

                String fileName = inet.substring(inet.lastIndexOf("/") + 1);

                File f = new File(filePath);
                f.mkdirs();
                String abs = filePath + fileName;
                f = new File(abs);                      


                os = new BufferedOutputStream(new FileOutputStream(abs));

                buf = new byte[1024];

                /*
                 * This loop reads the bytes and updates a progressdialog

                while ((ByteRead = is.read(buf)) != -1) {

                    os.write(buf, 0, ByteRead);
                    ByteWritten += ByteRead;

                    final int tmpWritten = ByteWritten;
                    runOnUiThread(new Runnable() {

                        }

                    });
                }

                runOnUiThread(new Runnable() {

                        dlDialog.setTitle("Startar");

                is.close();
                os.flush();
                os.close();


                Thread.sleep(200);

                dlDialog.dismiss();

                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setDataAndType(Uri.fromFile(new File(abs)),
                        "application/vnd.android.package-archive");
                startActivity(intent);
                finish();

            } catch (Exception e) {
                e.printStackTrace();

            }

        }
    }).start();

}
}

您无法强制安装APK ...

如果是这样，任何人都可以在某些服务器上隐藏病毒或间谍软件，当用户点击链接时，它会自动安装......

只需将要安装的apk文件放在服务器上，让超链接指向它...就像zip-archive，movie或其他可执行文件一样。

浏览器只需下载apk并安装它（如果用户需要）。用户当然需要在他的设置中激活非市场应用程序......（如上面的链接所述）

我希望这可以帮助你...
