There are 2 type of Non - system applications :

1. Apps downloaded from Google Play Store
2. Preloaded apps by device manufacturer

This code will return a list of all above applications:

ArrayList mAllApp = 
        mPackageManager.getInstalledApplications(PackageManager.GET_META_DATA);

for(int i = 0; i < mAllApp.size(); i++) {
    if((mAllApp.get(i).flags & ApplicationInfo.FLAG_SYSTEM) == 0) {
         // 1. Applications downloaded from Google Play Store
        mAllApp1.add(mAllApp.get(i));
    }

    if((mAllApp.get(i).flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
        // 2. Applications preloaded in device by manufecturer
        mAllApp1.add(mAllApp.get(i));
    }
}
