installing app and get result
<p>I installed an app to my device:</p>

<pre><code>Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(apk_file, "application/vnd.android.package-archive");
</code></pre>

<p>But how can I receive a result of installing (is app installing ok or user cancel installing)</p>
