Isha，我们在android中每30秒重复一次任务有很多解决办法：所以你可以使用具有后延迟的android处理程序来完成它，它将在30秒后调用。

new Handler().post(new Runnable() {
            @Override
            public void run() {
                //code here which you need to repeat after 30 secs.
                Toast.makeText(MainActivity.this, "Call after 30 secs", Toast.LENGTH_SHORT).show();
                new Handler().postDelayed(this, 1000 * 30);
            }
        });

我希望它会对你有所帮助。如果您想阅读有关Handler的信息，可以点击以下链接： https://developer.android.com/reference/android/os/Handler.html#postDelayed(java.lang.Runnable，长）

如何在android中每隔30秒将Geo-location的新数据插入到SQLite数据库中？
