BroadCast和Activity之间的数据传输

Question

如何将数据从BroadcastReceiver传输到活动？ 我试图与意图，但它返回null。

MyBroadcastReceiver class: 

public class MyBroadcastReceiver extends BroadcastReceiver { 

    private static final String TAG = "MyBroadcastReceiver"; 
    @Override 
     public void onReceive(Context context, Intent intent) { 

     ...................................... 
      ...................................... 

     String phoneNumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); 
      Intent i = new Intent(context, CalendarCall.class); 
     i.putExtra("number", phoneNumber); 
      (startActivity(i)-> i can't start Activity under BroadcastReceiver,what is another way to do that?) 
     Log.d(TAG, phoneNumber); 
       } 
     } 
} 

} 

主要活动：

Intent intent = getIntent(); 
     String number = intent.getStringExtra("number"); 
     Log.d(TAG, "Number: " + number);

      ...................................... 

     String phoneNumber = extras.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); 
      Intent i = new Intent(context, CalendarCall.class); 
     i.putExtra("number", phoneNumber); 
     context.startActivity(i); 
     Log.d(TAG, phoneNumber); 
       }
