进口android.util.Log;
进口android.view.Menu;公共类MainActivity延伸活动{ @覆盖
公共无效的onCreate(捆绑savedInstanceState){
super.onCreate(savedInstanceState);
的setContentView(R.layout.activity_main);
Log.d(流动,1);
在意向=新意图(com.yal.Communication.Communicationservice);
this.startService(在);
// startService(新意图(MainActivity.this,Communicationservice.class));
Log.d(流动,2);
} @覆盖
公共布尔onCreateOptionsMenu(菜单菜单){
。getMenuInflater()膨胀(R.menu.activity_main,菜单);
返回true;
}
}
下面是Mainfest.xml
<应用
机器人:图标=@绘制/ ic_launcher
机器人:标签=@字符串/ APP_NAME
机器人:主题=@风格/ AppTheme> <活性GT; ...< /活性GT;
<服务机器人:启用=真正的机器人:名字=com.yal.Communication.Communicationservice>< /服务>
< /用途>
错误

解决方案
您需要检查意向过滤器。
下面片段将帮助你。
<服务机器人:名字=com.yal.Communication.Communicationservice>
&所述;意图滤光器>
<作用机器人:名字=com.yal.Communication.Communicationservice/>
&所述; /意图滤光器>
< /服务>
然后就可以调用这个服务,如如下:
意图serviceIntent =新意图(com.yal.Communication.Communicationservice);
startService(serviceIntent);
Here is my service class
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;
public class Communicationservice extends Service {
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
super.onCreate();
Log.d("I AM Service","Service Created");
}
@Override
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
}
}
Here is my Main Activity
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.util.Log;
import android.view.Menu;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.d("flow","1");
Intent in = new Intent("com.yal.Communication.Communicationservice");
this.startService(in);
//startService(new Intent(MainActivity.this,Communicationservice.class));
Log.d("flow","2");
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Here is Mainfest.xml
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity > ... </activity>
<service android:enabled="true" android:name="com.yal.Communication.Communicationservice"></service>
</application>
Error
11-02 16:34:17.939: D/flow(1390): 1
11-02 16:34:17.939: W/ActivityManager(92): Unable to start service Intent { act=com.yal.Communication.Communicationservice }: not found
11-02 16:34:17.939: D/flow(1390): 2
解决方案
you need to check Intent-Filter.
below snippet will help you.
<service android:name="com.yal.Communication.Communicationservice">
<intent-filter>
<action android:name="com.yal.Communication.Communicationservice" />
</intent-filter>
</service>
Then you can call this services like follows.
Intent serviceIntent = new Intent("com.yal.Communication.Communicationservice");
startService(serviceIntent);
