I have a list activity which display all running applications in the device. it's displaying a default icon for all application . but I need to get actual application Icon for each application in the list.
public class ApplicationList extends ListActivity {
DataHelper dh;
ImageView vi;
private Drawable icon;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.applist);
dh = new DataHelper(getApplicationContext());
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
Log.d("Test1", "INSERTING APP LIST TO SERVER DB");
List<ResolveInfo> list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
ArrayList<String> applist = new ArrayList<String>();
for(ResolveInfo rInfo: list){
applist.add(rInfo.activityInfo.applicationInfo.loadLabel(pm).toString() );
}
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.installedapp, R.id.textView1, applist);
setListAdapter(adapter);
}
How to get the icon of other applications (Android)
I tried this link but I did not get things solved. so can any one help me out. thanks!
try like this
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
Drawable[] icons=new Drawable[packs.size];
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
icons[i]= p.applicationInfo.loadIcon(getPackageManager());
}
try this:
Icon icon = p.applicationInfo.loadIcon(getPackageManager());
imageView.setImageDrawable(icon);
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 getPackages() {
ArrayList apps = getInstalledApps(false); /* false = no system packages */
final int max = apps.size();
for (int i=0; i
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;
}

I am brand new to programming, and specially to android. I am trying to get all the installed application details, such as the label name and the icon to be displayed in a list view, and to launch it when a particular app is been clicked.. Currently I am trying to work with how to display them. i tried many of the source codes available in the net. Finally i ended up using this code which I got from this site, http://www.androidsnippets.com/get-installed-applications-with-name-package-name-version-and-icon. It seems to work but the output i get in the emulator is kind of weird..
I am kind of confused not knowing what to do.
My code:
public class SecondPage extends ListActivity {
private static final String TAG = "MyActivity" ;
ListView lv;
ArrayList al;
#Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
lv = getListView();
al = getPackages();
lv.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, al));
}
class PInfo {
private String appname = "";
private String pname = "";
private String versionName = "";
private int versionCode = 0;
private Drawable icon;
private void prettyPrint() {
Log.v(TAG, appname + "\t " + pname + "\t " + versionName + "\t " + versionCode);
}
}
private ArrayList<PInfo> getPackages() {
ArrayList<PInfo> apps = getInstalledApps(false); /* false = no system packages */
final int max = apps.size();
for (int i=0; i<max; i++) {
apps.get(i).prettyPrint();
}
return apps;
}
private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
ArrayList<PInfo> res = new ArrayList<PInfo>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null)) {
continue ;
}
PInfo newInfo = new PInfo();
newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(newInfo);
}
return res;
}
}
My XML file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#android:id/list"></ListView>
</LinearLayout>
And this is one line of the list view i get in the emulator:
com.example.sample3.app.$PInfo#b3ec49c0
Replace your getPackages() method with the following code
private ArrayList<PInfo> getPackages() {
ArrayList<PInfo> apps = getInstalledApps(false); /* false = no system packages */
ArrayList<String> appName = new ArrayList();
final int max = apps.size();
for (int i=0; i<max; i++) {
apps.get(i).prettyPrint();
appName.add(apps.get(i).appname);
}
return appName;
}
A new ArrayList of type String is used to store the appnames and this list is being given to the ListView
Hope this helps you.
Starting from this code
class PackageInfoData{
private String appname = "";
private String pname = "";
private String versionName = "";
private int versionCode = 0;
private Drawable icon;
}
private void getInstalledPackages() {
ArrayList<PackageInfoData> installedApps = getInstalledApps(false); /* false = no system packages */
for (int i=0; i<installedApps.size(); i++) {
Log.i("Instlled app","APp Name:"+installedApps.get(i).appname+"package:"+installedApps.get(i).pname);
}
return installedApps ;
}
private ArrayList<PackageInfoData> getInstalledApps(boolean getSysPackages) {
ArrayList<PackageInfoData> res = new ArrayList<PackageInfoData>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null)) {
continue ;
}
PackageInfoDatanewInfo = new PackageInfoData();
newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(newInfo);
}
return res;
}
That returns a list of applications installed in the device, i want that this list is collapsibile. So for example, i have a button and when i click it the list will appears and when i click again the button the list disappears. How can i do it?
i want the application list that is installed from google play or from any external storage, but not the pre installed system application.
i just use below code.....
class PInfo {
private String appname = "";
private String pname = "";
private String versionName = "";
private int versionCode = 0;
private Drawable icon;
private void prettyPrint() {
Log.v("", "*** appname = " + appname + " *** \n" + " packagename = " + pname + "\n" + " version name = " + versionName + "\n" + " version code = " + versionCode + " \n\n\n\n");
}
}
private ArrayList<PInfo> getPackages() {
ArrayList<PInfo> apps = getInstalledApps(true); /* false = no system packages */
final int max = apps.size();
int i = 0;
for (i=0; i<max; i++) {
apps.get(i).prettyPrint();
}
Log.v(TAG, "Total APPs = "+i);
return apps;
}
private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
ArrayList<PInfo> res = new ArrayList<PInfo>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null)) {
continue ;
}
PInfo newInfo = new PInfo();
newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(newInfo);
}
return res;
}
but this code gives me information of system application also.....
can anybody know how to get only installed application except the installed system application ?
thanks....
To discover if your application is a system application you can use the following code:
PackageManager pm = getPackageManager();
List<ApplicationInfo> installedApps = pm.getInstalledApplications(0);
for (ApplicationInfo aInfo: installedApps) {
if ((aInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
// system application
} else {
//user application
}
}
If you need to discover if an application is installed from a market you need to use the following method of Package: getInstallerPackageName. It will return the packageName of the application that installed your application.
public class AppList extends Activity {
private ListView lView;
private ArrayList results = new ArrayList();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lView = (ListView) findViewById(R.id.list1);
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list) {
results.add(rInfo.activityInfo.applicationInfo
.loadLabel(pm).toString());
Log.w("Installed Applications", rInfo.activityInfo.applicationInfo
.loadLabel(pm).toString());
}
lView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, results));
}
}
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 in bitmap?
Thanks!
try {
String pkg = "com.app.my";//your package name
Drawable icon = getContext().getPackageManager().getApplicationIcon(pkg);
imageView.setImageDrawable(icon);
} catch (PackageManager.NameNotFoundException ne) {
}
Check here for more details.
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();
}
}
Here is Link for reference
OR
You can download custom launcher code from My Github repository
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)
}
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;
}
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();
}
}
Okay i managed to make a button list all installed applications like this:
public void launcher(View v){
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
Intent pickIntent = new Intent(Intent.ACTION_PICK_ACTIVITY);
pickIntent.putExtra(Intent.EXTRA_INTENT, mainIntent);
myMenu.this.startActivity(mainIntent);
So when I click the button a window pops up like a dialog and lists all the applications. However, when I click any of the applications the dialog closes and nothing happens. how can I make these applications clickable?
Code would be preferrable and I'm a noobie so please be specific in your answer.
Thanks! :)
Here i am give one example which basically get all information of all install app from your device.
class PInfo {
private String appname = "";
private String pname = "";
private String versionName = "";
private int versionCode = 0;
private Drawable icon;
private void prettyPrint() {
Log.v(appname + "\t" + pname + "\t" + versionName + "\t" + versionCode);
}
}
private ArrayList<PInfo> getPackages() {
ArrayList<PInfo> apps = getInstalledApps(false); /* false = no system packages */
final int max = apps.size();
for (int i=0; i<max; i++) {
apps.get(i).prettyPrint();
}
return apps;
}
private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
ArrayList<PInfo> res = new ArrayList<PInfo>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null)) {
continue ;
}
PInfo newInfo = new PInfo();
newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(newInfo);
}
return res;
}
