Your Question is:- Get icons of all installed apps in android? you want list of install apps icon

Here is the code which help you to get install apps list with Application (icons,packages names).

**Declare variable in your Activity**

        appListMainArrayList = new ArrayList<>();
        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        List<ResolveInfo> resolveInfoList = packageManager.queryIntentActivities(intent, 0);

        for (ResolveInfo resolveInfo : resolveInfoList) {
            AppListMain appListMain = new AppListMain();
            appListMain.setAppIcon(resolveInfo.activityInfo.loadIcon(packageManager));
            appListMain.setAppName(resolveInfo.loadLabel(packageManager).toString());
