如何写contacts到sim card中？

需要验证sim contacts list full的情况，写了code，往sim card中添加contacts

 

ContentValues values = new ContentValues();
		values.put("tag", "allenpettle");
		values.put("number", "1234567");
		Uri uri = Uri.parse("content://icc/adn");
		ContentResolver resolver = getContentResolver();
		//add 100 contacts one time.
		for(int i=0; i<100; i++){
			resolver.insert(uri, values);
		}

 别忘了在manifest中添加permission: android.permission.WRITE_CONTACTS
