Get icons of all installed apps in android

Question

I want to get icons of my all installed apps. Can I get that icons using package manager? Is there any function for it? Or any other way to get icons of all installed apps i

Try this way: Make a class called PackageInformation:

public class PackageInformation {

    private Context mContext;

    public PackageInformation(Context context) {
        mContext = context;
    }

    class InfoObject {
        public String appname = "";
        public String pname = "";
        public String versionName = "";
        public int versionCode = 0;
        public Drawable icon;


        public void InfoObjectAggregatePrint() { //not used yet
            Log.v(appname, appname + "\t" + pname + "\t" + versionName + "\t" + versionCode);
        }

    }

    private ArrayList < InfoObject > getPackages() {
        ArrayList < InfoObject > apps = getInstalledApps(false);
        final int max = apps.size();
        for (int i = 0; i < max; i++) {
            apps.get(i).prettyPrint();
        }
        return apps;
    }

    public ArrayList < InfoObject > getInstalledApps(boolean getSysPackages) {
        ArrayList < InfoObject > res = new ArrayList < InfoObject > ();
        List < PackageInfo > packs = mContext.getPackageManager().getInstalledPackages(0);
        for (int i = 0; i < packs.size(); i++) {
            PackageInfo p = packs.get(i);
            if ((!getSysPackages) && (p.versionName == null)) {
                continue;
            }
            InfoObject newInfo = new InfoObject();
            newInfo.appname = p.applicationInfo.loadLabel(mContext.getPackageManager()).toString();
            newInfo.pname = p.packageName;
            newInfo.versionName = p.versionName;
            newInfo.versionCode = p.versionCode;
            newInfo.icon = p.applicationInfo.loadIcon(mContext.getPackageManager());
            res.add(newInfo);
        }
        return res;
    }

}

tuck this away somewhere and now to access the info from your working Activity class do this:

PackageInformation androidPackagesInfo = new PackageInformation(this);
ArrayList < InfoObject > appsData = androidPackagesInfo.getInstalledApps(true);

for (InfoObject info: appsData) {
    Toast.makeText(MainActivity.this, info.appname, 2).show();
    Drawable somedrawable = info.icon;

}
