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:
Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(),“service work”,Toast.LENGTH_SHORT).show();
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:
Toast.makeText(context,“”+ phoneState +“”+ record,Toast.LENGTH_SHORT).show();
Toast.makeText(getApplicationContext(),“服务将被停止。”,Toast.LENGTH_SHORT).show();
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
}
答案 1 :(得分:1)
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;
}
