OnePlus 5無法通過音頻管理器在通話模式下啓動揚聲器

我試圖在通話模式下將設備音頻設置爲揚聲器。
它在我檢查的大多數設備上工作。OnePlus 5無法通過音頻管理器在通話模式下啓動揚聲器

我購買了OnePlus5設備，但沒有使用它。

final AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE); 
audioManager.stopBluetoothSco(); 
audioManager.setBluetoothScoOn(false); 
audioManager.setSpeakerphoneOn(true);

當我檢查的結果是假的：

audioManager.isSpeakerphoneOn() // return false

，我可以在logcat中看到，當我從原生撥號器，他們是用一些不同的對象設置揚聲器設置揚聲器：

我已經使用這個權限。 – motis10

我添加此權限可以在OnePlus5上運行！但仍然扔這個日誌。 – Blanke
