Permission Denial：不允许发送广播 android.intent.action.AIRPLANE_MODE

Question

我正在尝试以编程方式设置飞行模式。

Settings.System.putInt(context.getContentResolver(), Settings.Global.AIRPLANE_MODE_ON, 1);

Intent aeroPlaneIntent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
aeroPlaneIntent.putExtra("state", true);
context.sendBroadcast(aeroPlaneIntent);

设置 Global.AIRPLANE_MODE_ON 失败，就像我检查它返回 0 (OFF) 的状态一样

尝试广播它引发以下异常的意图：

有没有办法将飞行模式设置为开/关？ 请帮忙

Answer 1

关于小信息：

首先使用此权限..

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

更多信息：请查看conversation

Answer 2

以下内容已在 Android API 23 & 26 Emulators 上进行了测试和验证；

需要的manifest权限如下；

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" tools:ignore="ProtectedPermissions"/>

代码如下；

boolean turnOnOffAirplaneMode(boolean isTurnOn) {
    boolean result = true;
    try {
        Settings.Global.putInt(context.getContentResolver(),
                Settings.Global.AIRPLANE_MODE_ON, isTurnOn ? 1 : 0);
        // The below old code is now not necessary @ API Level 23, 26 ...
        //Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
        //context.sendBroadcast(intent);
    } catch (Exception e) {
        result = false;
    }
    return result;
}

APK 应使用相关的平台密钥进行签名，以上内容才能正常工作。在模拟器测试中，APK 使用 Google 签名密钥进行签名。密钥取决于设备的 OEM。
