自动开启 GPS

Automatically turn on GPS(自动开启 GPS)

问题描述

我在 google 上搜索了一下，找到了关于利用 Power Manager Bug 来解决这个问题的解决方案.但是由于该错误现已解决.那么现在我该如何解决这个应用程序启动时启动 GPS 的问题呢?请帮忙.

I googled about it and there were solutions regarding the exploitation of Power Manager Bug to resolve this issue. But as the bug has now been solved. So how can now I solve this issue of starting the GPS when the app starts? Please help.

推荐答案

使用这个函数:

private void turnGPSOn(){
    String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

    if(!provider.contains("gps")){ //if gps is disabled
        final Intent poke = new Intent();
        poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
        poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
        poke.setData(Uri.parse("3")); 
        sendBroadcast(poke);
    }
}

从 activity 的 onCreate() 方法调用此函数.

Make a call for this function from the onCreate() method of your activity.

或:

Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);

谢谢.
