Toast will always show in UI Thread.
You have got error beacause new Thread will run seperate from UI Thread. you are try to show Toast inside a Thread seperate from UI Thread.
Use this code :
Using runOnUiThread call make If the current thread is not the UI thread, the action is posted to the event queue of the UI thread.
Thread background = new Thread(new Runnable() {
public void run() {
try {
// Now Again Toast is running in UI Thread
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getBaseContext(),"Iam inside thread",Toast.LENGTH_SHORT).show();
}
});
}
catch (Throwable t)
{
// Now Again Toast is running in UI Thread
runOnUiThread(new Runnable() {
public void run() {
Toast.makeText(getBaseContext(),"URL exeption!"+t,Toast.LENGTH_SHORT).show();
}
});
}
Show toast message inside run method of Thread.
