從服務啓動意圖導致崩潰

Question

回覆：Move back to App after launching another App

我現在已經設立了服務但是，當涉及到實際發射運行命令我的應用程序部隊內的意圖來運行我的runCommand（）函數（見下文）關閉：

E/AndroidRuntime (5448): FATAL EXCEPTION: Thread-931 

E/AndroidRuntime (5448): android.util.AndroidRuntimeException: Calling startActvitiy() from outside of an Activity context requires the FLAT_ACTIVITY_NEW_TASK flas. Is this really what you want? 

E/AndroidRuntime (5448): at android.app.ContextImpl.startActivity(ContextImpl.java:864) 

E/AndroidRuntime (5448): at android.content.ContentWrapper.startActivity(ContextWrapper.java 276) 

E/AndroidRuntime (5448): at packagename.MainService.runCommand(MainService.java:164) 

所以我的問題是我將如何去啓動所需的意圖形式的服務？

我的服務類是：

public class MainService extends Service { 

boolean copied = false; 
private String mHandle; 
private static final int REQUEST_WINDOW_HANDLE = 1; 

@Override 
public IBinder onBind(Intent arg0) { 
    return null; 
} 

@Override 
public void onCreate() { 

} 

@Override 
public void onDestroy() { 

} 

@Override 
public void onStart(Intent intent, int startId) { 
    Thread usbUpdateThread = new Thread() { 
     public void run() {    
      while (true) { 
       while (!copied) { 
        try { 
         Thread.sleep(180000); 
        } catch (InterruptedException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
       } 
       runCommand("chmod -R 777 /media/cdrom/"); 
       copied = false; 
      } 
     } 
    }; 
    Thread InternetThread = new Thread() { 
     public void run() { 
      while (true){ 
        try { 
         Thread.sleep(3600000); 
        } catch (InterruptedException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
        runCommand("php update.php"); 

      } 
     } 
    }; 
    Thread CheckThread = new Thread() { 
     public void run() { 
      while (true) { 
        try { 
         Thread.sleep(300000); 
        } catch (InterruptedException e) { 
         // TODO Auto-generated catch block 
         e.printStackTrace(); 
        } 
        runCommand("sh check.sh"); 
       } 

     } 
    }; 

    InternetThread.start(); 
    CheckThread.start(); 
    usbUpdateThread.start(); 
} 


public boolean runCommand(String command) { 
    Intent intent = new Intent("jackpal.androidterm.RUN_SCRIPT"); 
    intent.addCategory(Intent.CATEGORY_DEFAULT); 
    intent.putExtra("jackpal.androidterm.iInitialCommand", command); 
    intent.putExtra("jackpal.androidterm.window_handle", MainActivity.mHandle); 
    startActivity(intent); 


    return true; 
} 

}

我的服務使用開始：

Intent intentService = new Intent(this, MainService.class); 
    this.startService(intentService); 

在我的主要活動

Answer 1

考慮增加此標誌：

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

Answer 2

試試這個，它會解決你的問題。

Intent mInMainAndroidAct= new Intent(getBaseContext(), myActivity.class); 
mInMainAndroidAct.addCategory(Intent.CATEGORY_DEFAULT); 
mInMainAndroidAct.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
mInMainAndroidAct.putExtra("jackpal.androidterm.iInitialCommand", command); 
mInMainAndroidAct.putExtra("jackpal.androidterm.window_handle", MainActivity.mHandle); 
getApplication().startActivity(mInMainAndroidAct);
