Determine if Android app is being used for the first time

Question

I am currently developing an android app. I need to do something when the app is launched for the first time, i.e. the code only runs on the first time the program is launch

Answer 1

I made a simple class to check if your code is running for the first time/ n-times!

Example

Create a unique preferences

FirstTimePreference prefFirstTime = new FirstTimePreference(getApplicationContext());

Use runTheFirstTime, choose a key to check your event

if (prefFirstTime.runTheFirstTime("myKey")) {
    Toast.makeText(this, "Test myKey & coutdown: " + prefFirstTime.getCountDown("myKey"),
                   Toast.LENGTH_LONG).show();
}

Use runTheFirstNTimes, choose a key and how many times execute

if(prefFirstTime.runTheFirstNTimes("anotherKey" , 5)) {
    Toast.makeText(this, "ciccia Test coutdown: "+ prefFirstTime.getCountDown("anotherKey"),
                   Toast.LENGTH_LONG).show();
}

• Use getCountDown() to better handle your code

FirstTimePreference.java
