Android 钉钉自动打卡

提前准备

首先我们需要一直不用的Android手机，插上公司的电源。下载安装钉钉并设置为极速打卡。

自动打开

我们只需要启动一个服务，定时打开钉钉应用后再返回即可。

防止熄屏

这华为手机并没有永不息屏的选项，所以我们需要设置一下防止自动息屏。

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // 设置不自动息屏
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON, WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        setContentView(R.layout.activity_main);
    }

打开钉钉，签到后返回

核心程序

/**
     * 
     * @param packageName 包名
     */
    public void openApplication(String packageName) {
        PackageManager packageManager = getPackageManager();
        PackageInfo pi = null;
        try {
            pi = packageManager.getPackageInfo(packageName, 0);
        } catch (PackageManager.NameNotFoundException e) {
        }
        Intent resolveIntent = new Intent(Intent.ACTION_MAIN, null);
        resolveIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        resolveIntent.setPackage(pi.packageName);
        List<ResolveInfo> apps = packageManager.queryIntentActivities(resolveIntent, 0);
        ResolveInfo resolveInfo = apps.iterator().next();
        if (resolveInfo != null) {
            String className = resolveInfo.activityInfo.name;
            Intent intent = new Intent(Intent.ACTION_MAIN);
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            ComponentName cn = new ComponentName(packageName, className);
            intent.setComponent(cn);
            startActivity(intent);
        }
    }

• 打开cmd查找钉钉的包名

adb devices

adb shell

pm list package | grep alibaba 查找阿里巴巴相关的所有包名，也可以直接pm list package查找所有包名

// 打开钉钉
String packageName = "com.alibaba.android.rimet";
                    openApplication(packageName);

// 延迟2s,自动打开
try {
                        Thread.sleep(2000); 
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

// 返回自动打卡app
String packageNameNew = "com.example.dingding";
                    openApplication(packageNameNew);

创建一个service来进行自动打卡,使用java的cron4j库来执行定时任务,使用可以参见以前的博客。JFinal用cron4j执行定时任务

• cron4j.jar下载地址

public class DingService extends Service {

    private final String TAG = "DingService";
    
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();

        Log.e(TAG, "Service Start!");

        ClockThread ct = new ClockThread();
        ct.start();

    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
    }

    /**
     *
     * @param packageName 包名
     */
    public void openApplication(String packageName) {...}

    public class ClockThread extends Thread {

        public void run() {

            Scheduler scheduler = new Scheduler();
            
            //设置打开时间为工作日的 7:50,11:50,13:50,17:50
            scheduler.schedule("50 7,11,13,17 * * mon,tue,wed,thu,fri", new Thread() {
                @Override
                public void run() {

                    String packageName = "com.alibaba.android.rimet";
                    openApplication(packageName);

                    try {
                        Thread.sleep(2000); 
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                    String packageNameNew = "com.example.dingding";
                    openApplication(packageNameNew);

                }
            });

            scheduler.start();

        }

    }
}

最后在MainActivity中启动服务即可。

随机时间

为了让打卡更加真实，每天的打卡时间尽可能尽量不一样。我们用一个Scheduler(调度任务)每天在固定时间如每天早上6点，创建四个时间随机的调度任务来完成每日的打卡。

    public class ClockThread extends Thread {

        public void run() {

            scheduler = new Scheduler();

            scheduler.schedule("0 6 * * mon,tue,wed,thu,fri", new Thread() {
                @Override
                public void run() {

                    if(scheduler1 != null){
                        scheduler1.stop();
                        scheduler1 = null;
                    }
                    if(scheduler2 != null){
                        scheduler2.stop();
                        scheduler2 = null;
                    }
                    if(scheduler3 != null){
                        scheduler3.stop();
                        scheduler3 = null;
                    }
                    if(scheduler4 != null){
                        scheduler4.stop();
                        scheduler4 = null;
                    }
                    // 随机在7:00 ~ 7:27之间打卡
                    // scheduler1  scheduler.schedule(new Random().nextInt(28)+" 7 * * *",new Thread())
                    // 随机在11:30 ~ 11:57之间打卡
                    // scheduler2  scheduler.schedule((30 + new Random().nextInt(28))+" 11 * * *",new Thread())
                    // 随机在13:00 ~ 13:27之间打卡
                    // scheduler3  scheduler.schedule(new Random().nextInt(28)+" 13 * * *",new Thread())
                    // 随机在17:30 ~ 17:57之间打卡
                    // scheduler4  scheduler.schedule((30 + new Random().nextInt(28))+" 17 * * *",new Thread())


                }
            });

            scheduler.start();

        }

    }
