當有呼出和呼入時，toast 應該出現在螢屏上，但它沒有出現。代碼不正確？清單前提：
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
Manifast（接收器）：
<receiver android:name=".model.CallReceiver"
android:enabled="true"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
</intent-filter>
</receiver>
主要活動
if (ContextCompat.checkSelfPermission( this, READ_PHONE_STATE)!=PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions( this, new String[]{READ_PHONE_STATE} , 369);
}
班級：
public class CallReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context , Intent intent) {
if (intent.getStringExtra( TelephonyManager.EXTRA_STATE )==TelephonyManager.EXTRA_STATE_OFFHOOK){
showToastMsg(context,"phone call is Started...");
}else { if (intent.getStringExtra( TelephonyManager.EXTRA_STATE )==TelephonyManager.EXTRA_STATE_IDLE){
showToastMsg(context,"phone call is Ended...");
}else { if (intent.getStringExtra( TelephonyManager.EXTRA_STATE )==TelephonyManager.EXTRA_STATE_RINGING){
showToastMsg(context,"Incoming Call...");
}
}
}
}
private void showToastMsg(Context c,String msg) {
Toast.makeText( c, msg, Toast.LENGTH_LONG).show();
}
}

當應用程式關閉時，您需要該服務來處理來電或去電。清單檔案
<receiver android:name=".services.CallRecevier">

使用此代碼可在 android 11 和 9 上運行
