嗨,我已经开发了一个用于获取位置并将其发送到服务器的 android 应用程序,它运行良好,但位置更新不起作用,一旦我必须获取位置并在半小时内发送到服务器一次,它当前正在运行,这个过程应该运行只有 9 小时到 17 小时,我该怎么做,请帮帮我..!
我的代码:
@Override

if (!provider.contains("gps")) { // if gps is disabled
final Intent poke = new Intent();

"com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
this.sendBroadcast(poke);
