無法從Android的服務類中啓動Activity

Hai嘗試使用service class.my服務函數獲取緯度和經度值。但我無法啓動gpsclass.am的活動，正在獲取force close.i加入清單文件也無法從Android的服務類中啓動Activity

清單文件中的類

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.javaorigin.android.sample.service"

我的代碼

public class MyService extends Service { 

String tag="TestService"; 
private Intent Information; 
@Override 
public void onCreate() { 
    super.onCreate(); 
    Toast.makeText(this, "Service created...", Toast.LENGTH_LONG).show();  
    Log.i(tag, "Service created..."); 
} 

@Override 
    public void onStart(Intent intent, int startId) {  
    super.onStart(intent, startId); 
    Intent i=new Intent(getBaseContext(),getLocation.class); 
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    this.startActivity(i);  Log.i(tag, "Service started..."); 
} 
@Override 
    public void onDestroy() { 
    super.onDestroy(); 
    Toast.makeText(this, "Service destroyed...", Toast.LENGTH_LONG).show(); 
} 

    @Override 
    public IBinder onBind(Intent intent) { 
    return null; 
}

應用此代碼，這將啓動接收機

 Intent myIntent = new Intent (context, getLocation.class); 
     myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     context.startActivity(myIntent);

嚴重......？

Caused by: android.util.AndroidRuntimeException: Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag. Is this really what you want?

Intent i = new Intent（getBaseContext（），getLocation.class）; i.addFlags（Intent.FLAG_ACTIVITY_NEW_TASK）; this.startActivity（i）;我也試過這個 – Mercy 2012-01-12 08:47:29

更新了以前的帖子。 – JoxTraex 2012-01-12 08:49:54

logcat messge？ – Mercy 2012-01-12 08:51:14

我ADDED在清單也應該更新我的清單文件 – Mercy 2012-01-12 09:11:37

請顯示您的清單... – 2012-01-12 09:14:25

我添加了我的清單文件 – Mercy 2012-01-12 09:22:37

您是否嘗試過除baseContext之外傳遞不同的上下文？我覺得我記得這方面可能不是你想要的東西，嘗試通過ApplicationContext以例如

Intent i=new Intent(getApplicationContext(),getLocation.class);

，而不是

Intent i=new Intent(getBaseContext(),getLocation.class);

同樣的力量close.i認爲問題是清單file.Hill我現在更新？ – Mercy 2012-01-12 09:14:28

是啊，如果你沒有它在清單中，那肯定是問題 – MikeIsrael 2012-01-12 09:19:53

我加了我的清單文件 – Mercy 2012-01-12 09:22:43

Intent myIntent = new Intent(getBaseContext(), myActivity.class); 
    myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    getApplication().startActivity(myIntent);
