hello expert,
i want to get information of all apk in mobile, like name,icon,date etc....
i refer check it but there are not satisfied solution. so can you help me?
From your activity you should call
List<ApplicationInfo> applications = getPackageManager().getInstalledPackages(0);
Then you can get the information by running though the applications list.
You can check http://developer.android.com/reference/android/content/pm/PackageManager.html#getInstalledApplications(int) for more info on the falgs you can use.
If you want the icon and install/update of an application you should instead use
List<PackageInfo> applications = getPackagerManager().getInstalledPackages(0);
This will give you a list of PackageInfos. Then you can acces the information you seek:
for(PackageInfo info : applications){
Drawable icon = info.applicationInfo.loadIcon(getContext());
long firstInstalled = info.firstInstallTime;
long lastUpdate = info.lastUpdateTime;
}
Checkout http://developer.android.com/reference/android/content/pm/PackageInfo.html to see what else you can get from the packageinfo.
In addition to the above answer,
You should also have a look at http://developer.android.com/reference/android/os/Build.html.
It holds various informations regarding the cellphone (or tablet)

When I open the Android main menu on my Android smartphone, I get a set of apps like Youtube, Calculator, Email clients etc. No system stuff or any libraries are visible there.
To retrieve these apps programamtically, I do:
PackageManager.getInstalledApplications(flag: Int)
where I get a list of ApplicationInfo, which also contains alot more than mentioned installed standard apps. What flag do I have to set to get only the same apps, which I see when I swipe up on my Smartphone?
val mainIntent = Intent(Intent.ACTION_MAIN, null)
mainIntent.addCategory(Intent.CATEGORY_LAUNCHER)
val appList = context.getPackageManager().queryIntentActivities( mainIntent, 0)
You can try this to get all user apps (and the ones your launcher shows)
You might need to add additional permissions in your manifest above Android 10 though
Edit: If you want ApplicationInfo instead of ResolveInfo in your list you can retrieve it like this:
appList[your_index].activityInfo.applicationInfo
I'm developing a launcher application. I want to auto organize apps into folders with subjects as Game, Social Network, Entertainment, Tool... But I do not know based on the information of the application to know what type it.
Sample : http://dantri4.vcmedia.vn/tI0YUx18mEaF5kMsGHJ/Image/2014/07/APUS-Launcher-3-feb4a.jpg
As far as I know there is no straightforward way to achieve that.
The only thing that I could think about is to try to find some key words in the labels name of the apps.
Something like that:
private ArrayList<PackageInfo> searchPackageForString(PackageManager pm, String find){
List<PackageInfo> packs = pm.getInstalledPackages(0);
ArrayList<PackageInfo> results = new ArrayList<>();
for (PackageInfo pi : packs) {
if(pi.applicationInfo.loadLabel(pm).toString().toLowerCase().contains(find)){
results.add(pi);
}
}
return results;
}
Then you could try something like That:
searchPackageForString(getPackageManager(), "game");
I didn't try it but I thing that this is the only possibly direction.
Of course I can be wrong...
Edit:
Now that I looked in the pic you attached, I think that they check by find apps respond to Intents for action.
here some example:

I want to implement a listview showing android applications with their internet usage. Fir this, first i have to list all the apps, i have done this using PackageManager, like this:
packageManager = getPackageManager();
List<PackageInfo> packageList = packageManager
.getInstalledPackages(PackageManager.GET_META_DATA);
apkList = (ListView) findViewById(R.id.applist);
apkList.setAdapter(new ApkAdapter(this, packageList, packageManager));
But this code lists all system apps as well like : Android Sytem, Calculator,Calender, Status Bar, Live Wallpapers etc. which doesnt look appropriate. I tried to filter system apps using:
/*To filter out System apps*/
for(PackageInfo pi : packageList) {
boolean b = isSystemPackage(pi);
if(!b) {
packageList1.add(pi);
}
}
But then the code displays only installed apps, like whatsapp, tango, foursquare etc. It does not show apps like gmail, facebook, browser,maps.
Can anybody suggest how should i write the code that only displays list of application that actually use the internet. Thanks in advance!

One solution (maybe only one that works best and came to my head) is to use TrafficStats class that calculating data (TCP, UDP) transferred through network. Exactly in your case, you need to get data for each UID (each application has own UID).
All what you need to know if application trasfered more that zero bytes through network and when you know that, you can tell that "this application uses network".
Here is pseudo-code you could use:
List<Application> collection = new ArrayList<Application>();
Application app = null; // some custom object is good approach
PackageManager pm = getActivity().getPackageManager();
for (ApplicationInfo info: pm.getInstalledApplications(
PackageManager.GET_META_DATA)) {
// received data by application
long downloaded = TrafficStats.getUidRxBytes(info.uid);
// transmitted data by application
long uploaded = TrafficStats.getUidTxBytes(info.uid);
// filter system applications only
if ((info.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
// check if application has network usage
if (downloaded > 0 || uploaded > 0) {
// it's application you want
}
}
// non-system application
else {
if (downloaded > 0 || uploaded > 0) {
// it's application you want
}
}
}
It's important to say that TrafficStats is available from API 8 and also Before JELLY_BEAN_MR2, this may return unsupported on devices where statistics aren't available. I used this approach and never had a problems.
Note: Also I want to mention that maybe there are another possible approach(es) for example reading from some system files but this is (at least for me) hardcoded approach and i don't recommend to use it (also in various devices files can be on different places, have different content and different filename).
I hope it will help you solve your problem.
Application use internet will need Internet Permission
You can filter out those app by checked PackageInfo.permission
I need your help. I have two questions !
1) How can I know where an application I download comes from? Google Play or others.
I use something like that to get some informations about installed packages; but I didn't found the way to get where a package come from ! http://myandroidStore.com/myNewGame.apk for exemple.
List<PackageInfo> packages = getActivity() .getPackageManager()
.getInstalledPackages(0);
for (int i=0; i<packages.size(); i++) {
PackageInfo packageInfo = packages.get(i);
AppList tmpList = new AppList();
tmpList.applicationName = packageInfo.applicationInfo.loadLabel(getActivity()
.getPackageManager()).toString();
tmpList.packageName = packageInfo.packageName;
tmpList.versionName = packageInfo.versionName;
tmpList.versionCode = packageInfo.versionCode;
tmpList.provider = packageInfo.providers;
tmpList.firstInstallTime = packageInfo.firstInstallTime;
tmpList.lastUpdateTime = packageInfo.lastUpdateTime;
tmpList.signatures = packageInfo.signatures;
}
2) When "Unknown Sources" isn't selected I can't download application beyond Google Play.
Do you have an idea how Android check this verification?
1) How can I know where an application I download comes from? Google Play or others.
AFAIK the system provides no means for you to get this information. If you are interested in obtaining it you'd have to make seperate apk files with something unique embedded in them, that way you'd know based on that unique string where the apk came from at runtime.
2) When "Unknown Sources" isn't selected I can't download application beyond Google Play. Do you have an idea how Android check this verification?
I assume that the PackageManager is what is making the check for this. Not certain though.
Hi I want to get a list of all of the installed applications on the users device I have been googling for the longest time but can't find what i want this link was the closest though and works fine except me being new don't understand how to use the method getPackages(); and create a list with it
http://www.androidsnippets.com/get-installed-applications-with-name-package-name-version-and-icon
Any help on how to create the actual list would be a major help i have all that code already in just can't get the list to actually show thanks for any help
I was working on something like this recently. One thing I'll say up front is to be sure and perform this in a separate thread -- querying the application information is SLOW. The following will get you a list of ALL the installed applications. This will include a lot of system apps that you probably aren't interested in.
PackageManager pm = getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(0);
To limit it to just the user-installed or updated system apps (e.g. Maps, GMail, etc), I used the following logic:
List<ApplicationInfo> installedApps = new ArrayList<ApplicationInfo>();
for(ApplicationInfo app : apps) {
//checks for flags; if flagged, check if updated system app
if((app.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) {
installedApps.add(app);
//it's a system app, not interested
} else if ((app.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
//Discard this one
//in this case, it should be a user-installed app
} else {
installedApps.add(app);
}
}
EDIT: Also, to get the name and icon for the app (which is probably what takes the longest -- I haven't done any real deep inspection on it -- use this:
String label = (String)pm.getApplicationLabel(app);
Drawable icon = pm.getApplicationIcon(app);
installedApps should have a full list of the apps you need, now. Hope this helps, but you may have to modify the logic a bit depending on what apps you need to have returned. Again, it is SLOW, but it's just something you have to work around. You might want to build a data cache in a database if it's something you'll be accessing frequently.
