    <p>I'm trying to install apps from Google Play. I can understand that on opening the Google Play store URL, it opens the Google Play and when I press the back button, the activity resumes.</p> <pre><code>Intent marketIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(appURL)); marketIntent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET); startActivity(marketIntent); </code></pre> <p>When I went back to the activity, I tried calling this <code>onResume()</code> to check if the app is installed, but I receive an error:</p> <pre><code>@Override protected void onResume() { super.onResume(); boolean installed = false; while (!installed) { installed = appInstalledOrNot(APPPACKAGE); if (installed) { Toast.makeText(this, "App installed", Toast.LENGTH_SHORT).show(); } } } private boolean appInstalledOrNot(String uri) { PackageManager pm = getPackageManager(); boolean app_installed = false; try { pm.getPackageInfo(uri, PackageManager.GET_ACTIVITIES); app_installed = true; } catch (PackageManager.NameNotFoundException e) { app_installed = false; } return app_installed ; } </code></pre> <p>The error is as follows:</p> <blockquote> <p>E/AndroidRuntime(796): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.appinstaller/com.example.appinstaller.MainActivity}: android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=market://details?id=com.package.name flg=0x40080000 }</p> </blockquote> <p>I guess the activity is <code>onPause()</code>. Is there a better way to implement it? I'm trying to check if the app has finished installing.</p>

    2. CO@SiddharthanAsokan If I understand correctly, what you are trying to achieve here is, start your app -> go to play store-> click install -> come back to your own activity -> start the newly installed app.. is that right?

    3. CONope go back to the app which I opened initially. I need to get to get some info about the installed app using PackageManager. This information retrieval starts after I install the app from the initial which used opened the web url.

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.
