hello expert,

i refer check it but there are not sa开发者_如何转开发tisfied 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)
