Check if application is installed - Android

Try this:

private boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        packageManager.getPackageInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

It attempts to fetch information about the package whose name you passed in. Failing that, if a NameNotFoundException was thrown, it means that no package with that name is installed, so we return false.

Note that we pass in a PackageManager instead of a Context, so that the method is slightly more flexibly usable and doesn't violate the law of Demeter. You can use the method without access to a Context instance, as long as you have a PackageManager instance.

Use it like this:

public void someMethod() {
    // ...
    
    PackageManager pm = context.getPackageManager();
    boolean isInstalled = isPackageInstalled("com.somepackage.name", pm);
    
    // ...
}

Note: From Android 11 (API 30), you might need to declare <queries> in your manifest, depending on what package you're looking for. Check out the docs for more info.

Since Android 11 (API level 30), most user-installed apps are not visible by default. In your manifest, you must statically declare which apps you are going to get info about, as in the following:

<manifest>
    <queries>
        <!-- Explicit apps you know in advance about: -->
        <package android:name="com.example.this.app"/>
        <package android:name="com.example.this.other.app"/>
    </queries>
    
    ...
</manifest>

Then, @RobinKanters' answer works:

private boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        packageManager.getPackageInfo(packageName, 0);
        return true;
    } catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

// ...
// This will return true on Android 11 if the app is installed,
// since we declared it above in the manifest.
isPackageInstalled("com.example.this.app", pm); 
// This will return false on Android 11 even if the app is installed:
isPackageInstalled("another.random.app", pm);

Robin Kanters' answer is right, but it does check for installed apps regardless of their enabled or disabled state.

We all know an app can be installed but disabled by the user, therefore unusable.

This checks for installed AND enabled apps:

public static boolean isPackageInstalled(String packageName, PackageManager packageManager) {
    try {
        return packageManager.getApplicationInfo(packageName, 0).enabled;
    }
    catch (PackageManager.NameNotFoundException e) {
        return false;
    }
}

You can put this method in a class like Utils and call it everywhere using:

boolean isInstalled = Utils.isPackageInstalled("com.package.name", context.getPackageManager())
