使用android拨打电话而无需离开应用

Question

I have an app that, due to lack of mobile data in all areas, uses phone connection to make a phone call. There is some important information on the screen in my app, so I want to place the call without leaving my app screen. Is there any way to do this?

Answer 1

Add the following permission in mainfest file

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

Use the below code to start calling

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "123456789" ));
startActivity(intent);
