为什么服务在 BOOT_COMPLETED 之后不启动？

Question

我完美地添加了我的后台服务运行但是我的 phone 关闭并打开然后我的接收器 class 在 get action android.intent.action.BOOT_COMPLETED.but 服务中没有 start.my 下面的代码请帮帮我！！！

public class ReceiverCall extends BroadcastReceiver {
    static final String ACTION = "android.intent.action.BOOT_COMPLETED";
    static final String ACTION1 = "android.intent.action.QUICKBOOT_POWERON";
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.v("log_tag", "Action :: "+intent.getAction());
         if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
                /* Setting the alarm here */
                Intent alarmIntent = new Intent(context, MyAlarmService.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
                AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
                Calendar calendar = Calendar.getInstance();
                calendar.setTimeInMillis(System.currentTimeMillis());
                manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), + (1000 * 60 * 2), pendingIntent);
                Log.v("log_tag", "REPEAT");
            }
    }

而且我还在manifeast中添加了权限。

    <uses-permission android:name="com.employeemanager.app.permission.C2D_MESSAGE" />
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

Answer 1

有可能您的应用安装在外部存储上，无法接收启动完成事件。您应该在清单中添加 android:installLocation="internalOnly"。

Answer 2

也许你打错了，但如果你想让 Intent 工作，你应该打电话给：

context.startService(alarmIntent);

让我知道这个日志 Log.v("log_tag", "Action :: "+intent.getAction()); 是否显示在您的 Logcat 上，也请告诉我这个 Log.v("log_tag", "REPEAT");。

我建议你的 BroadcastReceiver 是这样的：

public class ReceiverCall extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    Log.v("log_tag", "Action :: "+intent.getAction());
     if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {
            //make an intent to your Service as follows 
            Intent serviceIntent = new Intent(context, MyAlarmService.class);
            context.startService(serviceIntent);
        }
}

然后在你的 Service 在你的 Service 的 onCreate 添加这个：

/* Setting the alarm here */
Intent alarmIntent = new Intent(context, Whatever.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);
AlarmManager manager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), + (1000 * 60 * 2), pendingIntent);
Log.v("log_tag", "REPEAT");

我还建议您创建一个新的 BroadcastReceiver 并在其上执行您想重复的操作，然后将 whatever.class 替换为您的 BroadccastReceiver。
