在我的应用程序中（在同一制造商的两种类型的电视盒上运行，并且所有设备都是根目录的），我会从自己的服务器上检查我的应用程序的最新版本，如果有新版本可用，我会下载apk文件并尝试使用 pm install 指挥部。虽然我从未启动过任何安装apk的活动，但它会自动从intent打开活动 Intent intent = new Intent(Intent.ACTION_VIEW); . 我从来没用过 Intent.ACTION_VIEW 在我的整个项目中，我假设android DownloadManager 自动打开此活动，我想阻止它这样做。知道怎么做吗？
这是我的密码：

//this is the method where I download the apk
//I'm putting only the important parts to make the question as short as possible
private void downloadApk() {
        if (status == State.DOWNLOADING)
            return;
        setStatus(State.DOWNLOADING);
        String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
        String fileName = appType + versionInfo.getVersionName() + ".apk";
        destination += fileName;
        Uri uri = Uri.parse("file://" + destination);

        String url = versionInfo.getUrl();

        DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
        request.setDescription("Downloading new Hub version");
        request.setTitle("Downloading");

        request.setDestinationUri(uri);
        downloadId = manager.enqueue(request);
        monitorDownloadPercentage();

        mContext.registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
    }

此方法仅计算文件下载的百分比，并使用该值调用回调。此计算值在其路径上更新一个progressbar，并设置为textview的文本。

private void monitorDownloadPercentage() {
        new Thread(new Runnable() {
            @Override
            public void run() {
                downloading = true;
                while (downloading) {
                    DownloadManager.Query q = new DownloadManager.Query();
                    q.setFilterById(downloadId);
                    Cursor cursor = manager.query(q);
                    cursor.moveToFirst();
                    int bytes_downloaded = cursor.getInt(cursor
                            .getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
                    int bytes_total = cursor.getInt(cursor.
                            getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));

                    if (upgradeStateListener != null) {
                        upgradeStateListener.onDownloading((float) bytes_downloaded / bytes_total * 100);
                    }
                    if (cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS)) == DownloadManager.STATUS_SUCCESSFUL) {
                        downloading = false;
                    }
                }
            }
        }).start();

    }

这是在下载完成时触发的广播接收器。我确信这个广播不会引起我的问题，因为代码中唯一可能引起它的地方是 onDownloadCompleted() 方法（它使用root权限安装apk，我已经对它的所有主体进行了注解，它仍然会弹出活动。

BroadcastReceiver onComplete = new BroadcastReceiver() {
        public void onReceive(Context ctxt, Intent intent) {
            long downloadId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, 0);
            final Cursor cursor = manager.query( new DownloadManager.Query().setFilterById(downloadId));
            if (cursor.moveToFirst()) {
                Uri uri ;
                final String downloadedTo = cursor.getString(
                        cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
                uri = Uri.parse(downloadedTo);
                Log.d(TAG, "onReceive: it's ok " + uri.getPath());
                upgradeStateListener.onDownloadCompleted(uri.getPath());
            }
            setStatus(State.DOWNLOADED);

            mContext.unregisterReceiver(this);

        }
    };
