sendwakefulwork并非总是使用CWAC-Wakeful-1.1.0打电话

Question

我已经有很长时间了，我发现了CWAC-Wakeful，这可以解决我的所有问题。我想... ：'（简而言之，为了解决问题，我已经实施了一个最简单的应用程序，该应用程序每60秒钟安排一次警报并每次记录。这是我的代码：

主动脉：

package com.par.hasard.mysimpleapplication;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = (Button)findViewById(R.id.myExportButton);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                MyLogManager.copyLogToClipboard(view.getContext());
                MyLogManager.emptyLogFile(view.getContext());
            }
        });
        try {
            MyLogManager.createLogFile(this);
            MyLogManager.write(this, "Application launchedn");
            MyAlarmPlanner.planAlarm_v2(this);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

myalarmplanner：

package com.par.hasard.mysimpleapplication;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.SystemClock;
import android.widget.Toast;
import com.commonsware.cwac.wakeful.WakefulIntentService;
import java.io.IOException;
public class MyAlarmPlanner {
    public static void planAlarm_v2(Context context) throws IOException {
        MyLogManager.write(context, "Beginning of planAlarm_v2n");
        WakefulIntentService.scheduleAlarms(new MyAppListener(), context, true);
        MyLogManager.write(context, "End of planAlarm_v2n");
    }
}

myAppListener：

package com.par.hasard.mysimpleapplication;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.os.SystemClock;
import com.commonsware.cwac.wakeful.AlarmReceiver;
import com.commonsware.cwac.wakeful.WakefulIntentService;
import java.io.IOException;
public class MyAppListener implements WakefulIntentService.AlarmListener {
    @Override
    public void scheduleAlarms(AlarmManager alarmManager, PendingIntent pendingIntent, Context context) {
        try {
            MyLogManager.write(context, "Beginning of scheduleAlarmsn");
            alarmManager.setExact(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime()+60000, pendingIntent);
            MyLogManager.write(context, "End of scheduleAlarmsn");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    @Override
    public void sendWakefulWork(Context context) {
        try {
            MyLogManager.write(context, "Beginning of sendWakefulWorkn");
            WakefulIntentService.sendWakefulWork(context, MyAppService.class);
            MyLogManager.write(context, "End of sendWakefulWorkn");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    @Override
    public long getMaxAge(Context context) {
        return (AlarmManager.INTERVAL_FIFTEEN_MINUTES * 2);
    }
}

myAppService：

package com.par.hasard.mysimpleapplication;
import android.content.Intent;
import com.commonsware.cwac.wakeful.WakefulIntentService;
import java.io.IOException;
public class MyAppService extends WakefulIntentService {
    public MyAppService(){
        super("MyAppService");
    }
    @Override
    protected void doWakefulWork(Intent intent) {
        try {
            MyLogManager.write(this, "Beginning of doWakefulWorkn");
            MyAlarmPlanner.planAlarm_v2(this);
            MyLogManager.write(this, "End of doWakefulWorkn");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

wawsful.xml：

<WakefulIntentService
    listener="com.par.hasard.mysimpleapplication.MyAppListener"
    />

所有这些都可以很好地工作，但是有时它不会记录任何内容。我认为这是由于我的手机睡眠模式（索尼Xperia）。但是在其他手机上似乎具有相同的行为。这是日志的示例：

有人可以帮我吗？

就时间间隙而言，很可能是在Android 6.0 设备上遇到打doe模式，或者某些制造商在较旧设备上提供的等效产品（例如，索尼的耐力模式）。除了将您的应用程序添加到适当的白名单（例如，为打dos，设置> Apps>（Gear Icon）>特殊访问>优化电池）之外，您几乎无法做到。

欢迎您切换到API级别23 设备上的setExactAndAllowWhileIdle()，但是：

• 您不会每分钟得到控制（我认为它仅限于每9分钟）

• 当您获得控制时，您将无法获得Internet访问（可能是您尝试实现的任何方法所必需的）

• 这对制造商特定的Pre-6.0设备无济于事（因为该方法不存在）

总体而言，设计您的应用程序来处理打ze模式，并且不认为它将在后台得到太多的控制，这是一种更可靠的方法。
