How to save data in Android app

This post will be about saving data to text file in Android development. Android uses a class called SharedPreferences. Within your activity create an instance of the class

SharedPreferences sp;
TextView tv;
Button b1;
EditText et1;

Then name a string that will be the name of the file.

final static String filename = "MyData";

Within the onCreate bundle method make your declaration.

sp = getSharedPreferences(filename,0);

tv = (TextView)findViewById(R.id.textView1);

b1 = (Button)findViewById(R.id.button1);

et1 = (EditText)findViewById(R.id.edit1);

tv.setText(sp.getString("key","No data yet");


public void onClick() {

String test = et1.getText().toString();

SharedPreferences.Editor editor = sp.edit();

editor.putString("mykey",test);

sp.commit();


}

How to create a thread in Android Development

I figured it's been a while since making a post on Android development, so today I will provide an example of a thread. A thread is a way that multiple activities can occur simultaneously in Android while using memory in an efficient way. In an Android app, it is standard to have an intro screen begin before being passed to a home activity or menu. Below is an example.

Thread myTimer = new Thread() {

public void run() {

try {

int timer =0 ;
while(time<5000) {


timer = timer + 100;
sleep(100);

}

startActivity(new Intent("com.activityname.clear"));
} catch(Exception e) {

e.printstacktrace();

}


}



};

myTimer.start();
