I want list of all applications installed on the device which use a specific permission like INTERNET.
i am using this code , but not able to retrieve results , please help .
private ArrayList<String> getInstalledApps(Context context) {
ArrayList<String> results = new ArrayList<String>();
PackageManager packageManager = context.getPackageManager();
List<PackageInfo> applist = packageManager.getInstalledPackages(0);
Iterator<PackageInfo> it = applist.iterator();
while (it.hasNext()) {
PackageInfo pk = (PackageInfo) it.next();
if (PackageManager.PERMISSION_GRANTED == packageManager.checkPermission(Manifest.permission.INTERNET, pk.packageName))
results.add("" + pk.applicationInfo.loadLabel(packageManager));
}
for (int i = 0; i <= results.size(); i++) {
Log.v("app using internet = ", results.toString());
}
return results;
}
I tried the code on android 2.2 emulator and it was working fine. Following is the working code:
private ArrayList<String> getInstalledApps(Context context) {
ArrayList<String> results = new ArrayList<String>();
PackageManager packageManager = context.getPackageManager();
List<PackageInfo> applist = packageManager.getInstalledPackages(0);
Iterator<PackageInfo> it = applist.iterator();
while (it.hasNext()) {
PackageInfo pk = (PackageInfo) it.next();
if ((pk.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
Log.v("system app using internet = ", ""+pk.applicationInfo.loadLabel(packageManager));
continue;
}
if (PackageManager.PERMISSION_GRANTED == packageManager
.checkPermission(Manifest.permission.INTERNET,
pk.packageName))
results.add("" + pk.applicationInfo.loadLabel(packageManager));
}
Log.v("app using internet = ", results.toString());
return results;
}
i had the same scenario, i solved it using the following check
PackageInfo p = packs.get(i);
ApplicationInfo a = p.applicationInfo;
if (PackageManager.PERMISSION_GRANTED != pm.checkPermission(Manifest.permission.INTERNET, p.packageName)) {
continue;
}
the packs variable is a array of class that holds information about the application installed and it consists of the objects with info of all the applications currently installed in system

I Already know how to get the package names of applications installed by the user.
But i cannot figure out how to get the package names of applications that are preinstalled or are system-ware like (Samsung Fit, Calender etc.) ??
List<ApplicationInfo> packages = context.getPackageManager().getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo packageInfo : packages) {
Log.d(TAG, "Package :" + packageInfo.packageName);
Log.d(TAG, "Launcher Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName));
}
ApplicationInfo is having a packageName field which provides you package name of the application.
You can use below code to get the list of system application PackageInfo,
public static ArrayList<PackageInfo> getSystemPackageInfos(final Activity context) {
ArrayList<PackageInfo> list = new ArrayList<PackageInfo>();
ArrayList<String> packageNames = new ArrayList<String>();
PackageManager pm = context.getPackageManager();
List<PackageInfo> pinfoList = pm.getInstalledPackages(0);
Collections.sort(pinfoList, PackageNameComparator);
for (PackageInfo pinfo : pinfoList) {
packageNames.add(pinfo.packageName);
boolean isSystem = false;
if (((pinfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) == 0)) {
isSystem = false;
} else {
isSystem = true;
}
if (pinfo.applicationInfo.sourceDir.startsWith("/data/app/") && isSystem) {
//Non-system app
isSystem = false;
}
if (!isSystem) {
continue;
}
Bitmap icon = null;
Drawable apkIcon = getApplicationIcon(pinfo.applicationInfo, context);
try {
icon = Bitmap.createBitmap(apkIcon.getIntrinsicWidth(), apkIcon.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(icon);
apkIcon.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
apkIcon.draw(canvas);
} catch (ClassCastException e) {
}
String name = pinfo.applicationInfo.loadLabel(pm).toString();
long apkSize = new File(pinfo.applicationInfo.sourceDir).length();
list.add(pinfo);
}
return list;
}
i have tried the code i pasted below ..but that gives me every application installed but then i need to check each of the app is mine or not by checking with the package name...Is there a code to where i can pass the package name to the phone system so that it gives me all the apps installed based on that package name.
PackageManager manager = getPackageManager();
Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
mainIntent.addCategory(Intent.CATEGORY_DEFAULT);
final List<ResolveInfo> apps = manager.queryIntentActivities(mainIntent, 0);
Collections.sort(apps, new ResolveInfo.DisplayNameComparator(manager));
ArrayList<String> oArrInstalledHomeApps = new ArrayList<String>();
if (apps != null)
{
final int count = apps.size();
for (int i = 0; i < count; i++)
{
ResolveInfo info = apps.get(i);
String strpackageName = info.activityInfo.applicationInfo.packageName;
if(strpackageName.contains ("com.ZZ."))
{
oArrInstalledHomeApps.add(strpackageName);
}
}
return oArrInstalledHomeApps;
}
Theres a cleaner way to do that.
final PackageManager pm = getPackageManager();
ArrayList<String> oArrInstalledHomeApps = new ArrayList<String>();
// get a list of installed apps.
List<ApplicationInfo> packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo packageInfo : packages)
{
Log.d(TAG, "Installed package :" + packageInfo.packageName);
Log.d(TAG, "Launch Activity :" + pm.getLaunchIntentForPackage(packageInfo.packageName));
if (packageInfo.packageName.contains("com.ZZ."))
{
oArrInstalledHomeApps.add(packageInfo.packageName);
}
}
return oArrInstalledHomeApps;
Copied shamelessly from this link
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));
}
}
How can I check that? Do i have to use PackageManager? Thank you :D
I check it this way (check if the returned value is unequal to null):
public static Intent findFacebookClient(Context con)
{
final String[] FacebookApps = {"com.facebook.android", "com.facebook.katana"};
Intent facebookIntent = new Intent();
facebookIntent.setType("text/plain");
final PackageManager packageManager = con.getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(facebookIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (int i = 0; i < FacebookApps.length; i++)
{
for (ResolveInfo resolveInfo : list)
{
String p = resolveInfo.activityInfo.packageName;
if (p != null && p.startsWith(FacebookApps[i]))
{
facebookIntent.setPackage(p);
return facebookIntent;
}
}
}
return null;
}
final PackageManager pm = getPackageManager();
List<ApplicationInfo> packages = pm
.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo packageInfo : packages) {
Log.d(TAG, "Installed package : " + packageInfo.packageName);
}
Then you can check if packageInfo.packageName is equal to some string which contains the package name of that application.
I have the following code and it works well to fetch the details of all applications installed in android but when i use a filter using isSystemPackage(ResolveInfo) it gives force close.
try {
lView = (ListView) findViewById(R.id.list1);
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
{
List<ResolveInfo> list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list) {
if (isSystemPackage(rInfo)) {
results.add(rInfo.activityInfo.applicationInfo.loadLabel(pm).toString());
Log.w("Installed Applications", rInfo.activityInfo.applicationInfo
.loadLabel(pm).toString());
}
}
}
} catch(Exception ex) {
Toast.makeText(getApplicationContext(), ex.toString(), 4000).show();
}
it generates force closed
isSystemPackage() code is
private boolean isSystemPackage(ResolveInfo ri){
return ((ri.activityInfo.applicationInfo.flags&ApplicationInfo.FLAG_SYSTEM)!=0)?
true:false;
}
I tried to debug it but can't able to do it.
Got my Answer, This is for others to use this code.
List<ApplicationInfo> list = getPackageManager().getInstalledApplications(PackageManager.GET_UNINSTALLED_PACKAGES);
for (int n=0;n<list.size();n++) {
if((list.get(n).flags & ApplicationInfo.FLAG_SYSTEM)!=1)
{
results.add(list.get(n).loadLabel(pm).toString());
Log.w("Installed Applications", list.get(n).loadLabel(pm).toString());
}
}
cheers :)
Please try this approach. It works for me:
List<ApplicationInfo> applications = getPackageManager().getInstalledApplications(PackageManager.GET_UNINSTALLED_PACKAGES);
for (int n=0; n < applications.size(); n++)
{
if ((applications.get(n).flags & ApplicationInfo.FLAG_SYSTEM) != 1)
{
Log.i(tag , "Non-System Aplication name " + applications.get(n).name);
}
}
