Question

I need to write some util class by myself and I need the packagename of android app.
While I found the packageManager which only can be used in Activity and so on that has context. I only want to get packagename in my class which will be used in android app. So how can I do this? Thank you!

Answer 1

Use : getPackageManager().getPackageInfo(getPackageName(), 0).packageName
Or just MyContext.getPackageName()

You can also create a function:

public String getPackageName(Context context) {
    return context.getPackageName();
}
