How to launch another application from my application in android

Question

I want to open another application from my application. I know I should use Intent for that, but I am not sure how to use that.

Answer 1

You are right! Intent is used to launch applications. Note: you should know the ID of the application you wish to open.

Intent appIntent= getPackageManager().getLaunchIntentForPackage("<YOUR_PAKCAGE_NAME | APPLICATION ID>"); // Application id looks like this - com.example.yourapplication
// Check if the app exists with provided ID by checking for null
if (appIntent != null) {
    startActivity(appIntent);
}

Hope this helps!
