Check phone for installed app?

pizzato16 · January 14th, 2011, 06:16 PM

Im putting together an app that has a function requiring an outside app to be downloaded ( if the user doesnt already have it) my question is, how would I code the activity to search the users phone for the installed app before auto downloading it? I dont want them to have to repeatedly download the app if its already on their phone. Thanks.

Should be able to use this to see what is installed and compare the package name against what you're looking for

Code:

PackageManager pm = getPackageManager();                
List<ApplicationInfo> list = pm.getInstalledApplications(0);
                
for (int i=0; i< list.size(); i++) 
{
    ApplicationInfo appInfo = list.get(i);
    String packageName = appInfo.packageName;
    String appLabel = (String) pm.getApplicationLabel(appInfo);
    Drawable icon = pm.getApplicationIcon(appInfo);
}
