Android飞行模式的打开与关闭

在Android4.2以前可以做到使用代码进行飞行模式的开关，步骤如下：

1、首先需要在AndroidManifest.xml中加入权限：

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

2、java代码中首先进行一个putString操作，然后发送一个广播，注意不发送广播是不会生效的：

if (Settings.System.getString(mContentResolver,
    					Settings.System.AIRPLANE_MODE_ON).equals("0")) {
    	//0表示飞行模式已关闭，1表示飞行模式已打开			
            Settings.System.putString(mContentResolver,
    						Settings.System.AIRPLANE_MODE_ON, "1");
            sendBroadcast(intent);
    } else {
    	Settings.System.putString(mContentResolver,
    						Settings.System.AIRPLANE_MODE_ON, "0");
    	sendBroadcast(intent);
    }

对于Android4.2以后的版本，只能说没办法。

Some device settings defined by [ Settings.System][Settings.System] are now read-only. If your app attempts to write changes to settings defined in[Settings.System][] that have moved to [ Settings.Global][Settings.Global], the write operation will silently fail when running on Android 4.2 and higher.

Even if your value for [ android:targetSdkVersion][android_targetSdkVersion] and [ android:minSdkVersion][android_minSdkVersion] is lower than 17, your app is not able to modify the settings that havemoved to[Settings.Global][] when running on Android 4.2 and higher.
