Below is the code for simple get request and res variable is not available inside Ui thread. How this can be achieved in android?
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread thread = new Thread(new Runnable(){
@Override
public void run(){
try {
String res = Utils.GetRequest("http://www.google.com");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, res, Toast.LENGTH_SHORT).show();
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
Answer
Okay, I found out that I haven’t declared the res variable as final.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Thread thread = new Thread(new Runnable(){
@Override
public void run(){
try {
final String res = Utils.GetRequest("http://www.google.com");
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, res, Toast.LENGTH_SHORT).show();
}
});
} catch (IOException e) {
e.printStackTrace();
}
}
});
thread.start();
}
