Android GPS 操作

强制关闭GPS：

// Intent GPSIntent = new Intent();
// GPSIntent.setClassName("com.android.settings",
// "com.android.settings.widget.SettingsAppWidgetProvider");
// GPSIntent.addCategory("android.intent.category.ALTERNATIVE");
// GPSIntent.setData(Uri.parse("custom:3"));
// try {
// PendingIntent.getBroadcast(this, 0, GPSIntent, 0).send();
// } catch (CanceledException e) {
// e.printStackTrace();
// }
