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;
    }
}

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.

How it works:

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.

How to use:

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