I wrote an app that handles incoming calls and answers them automatically. I want to set voice to phone's loud speaker and it works fine on android up to 4 but not 4.1 and 4.2.

Code:

AudioManager audioManager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
audioManager.setMode(AudioManager.MODE_IN_CALL);
audioManager.setSpeakerphoneOn(true);

I have required permission in my manifest:

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

I am getting a silent exception in my LogCat that says that I have not MODIFY_PHONE_STATE permission but I have defined this in manifest:

java.lang.SecurityException: Neither user 10046 nor current process has android.permission.MODIFY_PHONE_STATE.

根据docs，MODIFY_PHONE_STATE权限不适合您：

允许修改电话状态 - 开机、mmi 等。不包括拨打电话。

不供第三方应用程序使用。

它曾经在 2.3 之前工作，但从 v.2.3 开始进行了更改，因为该版本权限仅授予系统应用程序，这意味着要么预安装到 ROM 上的系统文件夹中，要么使用制造商的安全证书与制造商签署.

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

将上面添加到您的清单文件中
