Sory大家。首先,由于AUTO START MANAGER,在我的设备上关闭应用程序时,我的接收器无法工作。我感到愚蠢......当我试图解决它时,我学到了非常重要的东西。

首先是Android 6.0权限请求 Broadcast Receivers not working in Android 6.0 Marshmallow

其次:Android - Lollipop上的重复电话状态广播

...谢谢

我是Android的新手,我想学习BroadcastReceiver& Service。这个代码BroadcastReceiver监听摘机和闲置状态我的手机和发送意图服务做的事情。虽然应用程序运行正常。关闭应用程序后,BroadcastReceiver和Service不起作用。

更新:我注意到应用程序运行时和每个正常情况下,服务启动两次并停止两次。

我在服务启动时看到此消息:

  1. Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();

  2. Toast.makeText(getApplicationContext(),“service work”,Toast.LENGTH_SHORT).show();

  3. 再次1. Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();

    再次2. Toast.makeText(getApplicationContext(),“service work”,Toast.LENGTH_SHORT).show()

    我在服务停止时看到此消息:

    1. Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();

    2. Toast.makeText(getApplicationContext(),“服务将被停止。”,Toast.LENGTH_SHORT).show();

    3. 再次1. Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();

      再次2. Toast.makeText(getApplicationContext(),“服务将被停止。”,Toast.LENGTH_SHORT).show();

      一切都在重复。

以粘性方式启动服务。更改您的onStartCommand服务方式,如下所示

public int onStartCommand (Intent intent, int flags, int startId){

    boolean record = intent.getBooleanExtra("record", false);
    if (record) {
        Toast.makeText(getApplicationContext(), "service work", Toast.LENGTH_SHORT).show();
    }
    else {
        Toast.makeText(getApplicationContext(), "service will be stopped.", Toast.LENGTH_SHORT).show();
        stopSelf();
    }
     return START_STICKY;  // or START_REDELIVER_INTENT or START_STICKY_COMPATIBILITY
}

您必须在服务类

中添加以下内容
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

           // your business logic 

        return START_STICKY;
}
