我想在 ACTION_CALL 的帮助下按下我的移动应用程序中的按钮来拨打紧急号码，但我没有。 为什么？

Question

i want to make call on an emergency number by pressing the button in my mobile app with help of ACTION_CALL but i didn't. why?

I implemented CALL_PHONE permission in my manifest file.

<uses-permission android:name="android.permission.CALL_PHONE"/>

and this is my java code to call.

public void makeCall(View v){
        if (ActivityCompat.checkSelfPermission(this,Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED){
            Toast.makeText(getApplicationContext(), "making call", Toast.LENGTH_LONG).show();
            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_NO_USER_ACTION);
            callIntent.setData(Uri.parse("tel:108"));
            startActivity(callIntent);
        }else{
            Toast.makeText(getApplicationContext(), "making call is not possible", Toast.LENGTH_LONG).show();
            ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.CALL_PHONE},MY_PERMISSIONS_REQUEST_CALL_PHONE);
        }
    }

this code takes me onto default dialer of mobile.

How can i call on an emergency number directly by my app without reaching on default dialer?

Answer 1

 Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:"+123));//change the number

    if (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE},12);
    }else{
        startActivity(callIntent);
    }
