    <p>I am launching the default Youtube App installed on device to play a video. First, I want to check if the app exists on the device using PackageManager.</p> <p>If the app does not exists, I want to redirect the user to the Google Play to download the app.</p> <p>Below is the code snippet:</p> <pre><code> String appName = "com.google.android.youtube"; Boolean existFlg = false; Context context = getApplicationContext(); PackageManager packageManager = context.getPackageManager(); // get all installed app's info List&lt;PackageInfo&gt; pinfo = packageManager.getInstalledPackages(PackageManager.GET_ACTIVITIES); for (int i = 0; i &lt; pinfo.size(); i++) { String name = pinfo.get(i).packageName; if (name.equalsIgnoreCase(appName)) { existFlg = true; break; } } if (existFlg) { // start Youtube Native App Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube:"+video_id)); i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } // not installed else { // goto the market to download Youtube App Uri uri = Uri.parse("market://details?id=com.google.android.youtube"); Intent market = new Intent(Intent.ACTION_VIEW, uri); market.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); try { context.startActivity(market); } catch (android.content.ActivityNotFoundException ex) { // if market app not exist, goto the web of Google Play to download the Facebook App String googleURL = "https://play.google.com/store/apps/details?id=com.google.android.youtube"; Uri googleplay_webpage = Uri.parse(googleURL); Intent marketIntent = new Intent(Intent.ACTION_VIEW, googleplay_webpage); marketIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(marketIntent); } } </code></pre> <p>This code works perfectly well on <strong>Android 4.0.4</strong> and above. But when I am trying to run it on <strong>Android 2.3.4</strong> it ALWAYS redirects the user to the Google Play irrespective of whether the App is installed or not.</p> <p>Any idea as to how to make this compatible with Android 2.3.4 too ?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
