Android listing installed apps

How to get list of Installed Apps in Android

Android PackageManager class is used for retrieving various kinds of information related to the application packages that are currently installed on the device. You can get an instance of this class through getPackageManager().

Project Description

• In this Android 4 example, we will get list of installed apps in Android device and create custom ListView and populate its items using custom BaseAdapter.
• Here, we are going to implement OnItemClickListener event listener which calls onItemClick() callback method where we retrieve a particular row and create a object containing android application information and start another activity to display the installed app information such as Application name, package name, version, features, required permissions, path info, target SDK version, installed and modified date.

Environment Used

• JDK 6 (Java SE 6)
• Eclipse Indigo/Juno IDE for Java EE Developers
• Android SDK 4.0.3 / 4.2 Jelly Bean
• Android Development Tools (ADT) Plugin for Eclipse (ADT version 21.0.0)
• Refer this link to setup the Android development environment or this link to update to a latest version of Android SDK

Prerequisites

Create Android Project

• Create a new Android Project and enter the Application name as AppsList.
• Project name as AppsList.
• Enter the package name as com.ibc.android.demo.appslist.activity.
• Enter the Activity name as ApkListActivity.
• Enter the Layout name as main.
• Click Finish.

strings.xml

Open res/values/strings.xml and replace it with following content.

XML layout files

main layout file (main.xml)

This file defines a layout for displaying the result of installed apps in ListView widget. Open main.xml file in res/layout and copy the following content.

ListView row item layout file (apklist_item)

This layout defines only TextView widget. We can display of the icon of installed app in TextView using setCompoundDrawables() method.

Second Activity’s layout file (apkinfo.xml)

Create AppData class

This class extends android.app.Application which is used to maintain global application state, in this case contains an instance variable android.content.pm.PackageInfo. PackageInfo contains overall information about the contents of a package. This corresponds to all of the information collected from AndroidManifest.xml.

Create a new Java class “AppData.java” in package “com.ibc.android.demo.appslist.app” and copy the following code.

Custom BaseAdapter class

Create a new class “ApkAdapter” in “com.ibc.android.demo.appslist.adapter” package and copy the following code. This class extends android.widget.BaseAdapter to provide custom row layout and data for ListView.

Activity class

MainActivity class (ApkListActivity.java)

Open this activity class and copy the following code. In onCreate(), we get the list of installed apps and filtering out system app.

Second Activity class (ApkInfo.java)

Create a new class “ApkInfo.java” in package “com.ibc.android.demo.appslist.activity” and copy the following code.

AndroidManifest.xml

Output

Run your application
First Screen/Activity

Second Screen/Activity

And for just the packages:

adb shell ‘pm list packages -f’ | sed -e ‘s/.*=//’ | sort

Need to delete a bunch of things? This gives you an uninstall for everything that’s installed; cut and paste to adjust:

adb shell ‘pm list packages -f’ | sed -e ‘s/.*=//’ | sed -e ‘s/^/adb uninstall /’ | sort | less

how to save it as a notepad text file?
I found the answer:
adb shell pm list packages -f > b:\1.txt

Building up on banshee’s one liner, for me there was a trailing \r, removing it was needed, as such:

adb shell ‘pm list packages -f’ | sed -e ‘s/.*=//’ | sed ‘s/\r//g’ | sort

Only then I was able to do get the following to work:

How to Get List of Installed Apps in Android

Android PackageManager class is used to retrieve information on the application packages that are currently installed on the device. You can get an instance of PackageManager class by calling getPackageManager() . PackageManager provides methods for querying and manipulating installed packages and related permissions, etc. In this Android example, we we get list of installed apps in Android.

packageManager.getInstalledApplications() return a List of all application packages that are installed on the device. If we set the flag GET_UNINSTALLED_PACKAGES has been set, a list of all applications including those deleted with DONT_DELETE_DATA (partially installed apps with data directory) will be returned.

1. Creating application layout in xml

activity_main.xml

As you can see in the attached screenshot, we will be creating a ListView to show all of the installed applications in android.

snippet_list_row.xml

This layout is being used by the ListView Adapter for representing application details. It shows application icon, application name and application package.

2. Writing Java class

AllAppsActivity.java

This is the main application class that is used to initialize and list the installed applications. As getting the list of application details from PackageManage is a long running task, we will do that in AsyncTask. Also, this class is using custom Adapter “ApplicationAdapter” for custom ListView.

ApplicationAdapter.java

How to get a list of installed apps in Android 11

In Android 11, we can see a lot of updates that improve privacy. If your app uses the PackageManager methods to get the list of installed apps in the user’s device, you will have to make some changes in your code for devices using Android 11. In this blog post, we will be discussing all our options.

If you are already querying the user’s installed apps, the following code snippet will look familiar. This is how you can get a list of installed apps of the user.

Now for your users using Android 11, the code remains the same but it won’t work unless you add some additional elements in the AndroidManifest .

There are 3 different ways of querying installed apps of the user in Android 11. Let’s have a look at them:

Query specific packages

If you already know which apps you want to query just mention the package names inside the element in the AndroidManifest .

Query using intent filter

In case you don’t know all the package names of the apps that you want to query but there is a set of apps with similar functionality that you want to query then you can use an intent filter inside the element according to your requirements like it has been done in the code snippet below.

The element looks like but there are few differences. element has the following restrictions:

Query all the apps

If you want to query all the apps of the user like you were doing earlier, you need to include QUERY_ALL_PACKAGES permission in the AndroidManifest . It is a normal permission and it is granted as soon as the app is installed.

Ideally one should request the least amount of packages and respect the user’s privacy. In most cases this permission won’t be required, only for apps like launchers it makes sense to ask the user for permission to query all the installed apps on their phone.

There is one loophole that I noticed while exploring the element if you add android.intent.action.MAIN as the action element in the intent filter, you can see almost all the apps of the user without adding the permission since almost all apps would have this element in the AndroidManifest .

Package visibility in Android 11

On Android 10 and earlier, apps could query the full list of installed apps on the system using methods like queryIntentActivities() . In most cases, this is far broader access than is necessary for an app to implement its functionality. With our ongoing focus on privacy, we’re introducing changes on how apps can query and interact with other installed apps on the same device on Android 11. In particular, we’re bringing better scoped access to the list of apps installed on a given device.

To provide better accountability for access to installed apps on a device, apps targeting Android 11 (API level 30) will see a filtered list of installed apps by default. In order to access a broader list of installed apps, an app can specify information about apps they need to query and interact with directly. This can be done by adding a element in the Android manifest.

For most common scenarios, including any implicit intents started with startActivity() , you won’t have to change anything! For other scenarios, like opening a specific third party application directly from your UI, developers will have to explicitly list the application package names or intent filter signatures like this:

If you use Custom Tabs to open URLs, you might be calling resolveActivity() and queryIntentActivities() in order to launch a non-browser app if one is available for the URL. In Android 11 there’s a better way to do this, which avoids the need to query other apps: the FLAG_ACTIVITY_REQUIRE_NON_BROWSER intent flag. When you call startActivity() with this flag, an ActivityNotFoundException will be thrown if a browser would have been launched. When this happens, you can open the URL in a Custom Tab instead.

In rare cases, your app might need to query or interact with all installed apps on a device, independent of the components they contain. To allow your app to see all other installed apps, Android 11 introduces the QUERY_ALL_PACKAGES permission. In an upcoming Google Play policy update, look for guidelines for apps that need the QUERY_ALL_PACKAGES permission.

When targeting API level 30 and adding a element to your app, use the latest available release of the Android Gradle plugin. Soon we’ll be releasing updates to older Android Gradle plugin versions to add support for this element. You can find more information and use cases about Package Visibility in the developer documentation.
