How many 'context' we can use at a time simultaneously in different tasks?

Question

In Android programming, How many context we can use at a time in different simultaneously executed Threads Or Asynchronous tasks ?

Different invoking methods by which you can get context

getApplicationContext(),
getContext(),
getBaseContext()
or this (when in the activity class).

Also check this :

When to call activity context OR application context?

If I am running many Threads at a same time so is it Ok to pass getApplicationContext() in all of them or Some issue will occurs ???

Yes, you can pass getApplicationContext() any number of time (Background Tasks ) you want, getApplicationContext() simply returns context of the application.

you can find many of answers about difference between Context uses, Link

every context method have some limit to use it.

If you want to use a only One method or only one way to initialise some method calling in entire Activity.

Then declare Context as Globally as below, it have no limit to use in Activity.

import android.app.Activity;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    private Activity thisActivity;  //Activity object instance

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        thisActivity = this;    // Initialise with this(Context)

           //Or thisActivity = MainActivity.this;
    }
}

use thisActivity in place of Context
