Answer 1

try {
    String pkg = "com.app.my";//your package name
    Drawable icon = getContext().getPackageManager().getApplicationIcon(pkg);
    imageView.setImageDrawable(icon);
} catch (PackageManager.NameNotFoundException ne) {

}

Above answers are pretty good.

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**

private CustomAppListAdapter customAppListAdapter;
private ArrayList<AppListMain> appListMainArrayList;
private AppListMain appListMain;

Just call below function loadApps() in your Activity onCreate()

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_app_list);
    loadApps();
    
}

public void loadApps() {
    try {
        packageManager = getPackageManager();
        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());
            appListMain.setAppPackage(resolveInfo.activityInfo.packageName);
            appListMainArrayList.add(appListMain);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

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;

}

Answer 4

I find it the easiest way:

private List<ResolveInfo> installedApps() {
    final Intent main_intent = new Intent(Intent.ACTION_MAIN, null);
    main_intent.addCategory(Intent.CATEGORY_LAUNCHER);
    return package_manager.queryIntentActivities(main_intent, 0);
}

Now to get the icons, use this:

for(ResolveInfo ri : installedApps()) { 
    // to get drawable icon -->  ri.loadIcon(package_manager)
}

Answer 5

Here below is the code with which you can get the icons of all installed Apps.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            try {
                // try getting the properly colored launcher icons
                LauncherApps launcher = (LauncherApps) this.getSystemService(LAUNCHER_APPS_SERVICE);
                List<LauncherActivityInfo> activityList = launcher.getActivityList(packageName, android.os.Process.myUserHandle());
                drawable = activityList.get(0).getBadgedIcon(0);
            } catch (Exception e) {
            }
        }

        if (drawable == null) {

            try {
                getPackageManager().getApplicationIcon(packageName);
            } catch (PackageManager.NameNotFoundException e) {
                e.printStackTrace();
            }
        }
