权限拒绝:不允许发送广播android.intent.action.AIRPLANE_MODE

标签: android broadcast securityexception

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,就好像我检查它返回的状态0(OFF)

尝试广播意图会引发以下异常:

小信息:

首先使用此权限..

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

进一步信息:请检查此conversation

答案 1 :(得分:0)

以下内容经过Android API 23&amp; S测试和验证。 26个模拟器;

所需的清单权限如下;

<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应该使用相关的平台密钥进行签名,以便上述工作。在模拟器测试中,APK是使用Google Sign Keys签名的。密钥取决于设备的OEM。
