현재 실행중인 activity 구하기

현재 실행중인 activity를 구하는 방법에 대해 살펴보았다.

검색해보니 topActivity 를 이용해서 구하면 되겠구먼... 별거 아니네

private void test100()
{
 ActivityManager activityManager = (ActivityManager)this.getSystemService (Context.ACTIVITY_SERVICE);
    List<RunningTaskInfo> services = activityManager.getRunningTasks(Integer.MAX_VALUE);

    for (int i = 0; i < services.size(); i++) {
        Log.e("xxx",services.get(i).topActivity.toString());
    }
}

잘되는 것처럼 보임

위의 예제는 현재의 app에서 확인하는 테스트였다. 그렇다면 다른 app이 올라와 있는 상태라면 어떨까 그래서 broadcast receiver에 등록하여 제대로 처리하는지 알아보았다.

다른 app은 잘읽어 오는지 확인을 위해서 CONNECTIVITY_CHANGE 에 등록하였음

        if (action.equals("android.net.conn.CONNECTIVITY_CHANGE"))
        {
         NetworkInfo          mNetworkInfo;
         mNetworkInfo = (NetworkInfo) intent.getParcelableExtra("networkInfo");
         Log.d(TAG,"info:"+mNetworkInfo.getType() + " :: "+mNetworkInfo.getDetailedState());
         
         ActivityManager activityManager = (ActivityManager)context.getSystemService (Context.ACTIVITY_SERVICE);
         List<RunningTaskInfo> tasks = activityManager.getRunningTasks(Integer.MAX_VALUE);

         for (int i = 0; i < tasks.size(); i++) {
             Log.e("xxx",tasks.get(i).topActivity.toString());
         }
        }

결과는 이전과 동일... 이게 제대로 나왔다면 동작중인 app의 activity이름이 나와야 하는데...음 아무래도 서비스로 테스트를 해봐야겠음.

서비스로 변경해서 테스트

 public class ServiceClass extends Service{
  private Context mContext = null;
  Thread mThread;
  Runnable mRun = new Runnable() {  
   public void run() {
    try{
     for(;;){
      if( mContext == null ) break;
      printLog();
      Thread.sleep(5000);
     }
    }catch(Exception e){
     e.printStackTrace();
    }
   }
  };
  
     @Override
     public IBinder onBind(Intent intent) {
         return null;
     }
   
     @Override
     public void onStart(Intent intent, int startId) {
         Log.d("slog", "onStart()");
         mContext = this;
         super.onStart(intent, startId);
         mThread = new Thread(mRun);
         mThread.start();
     }
 
     public void printLog()
     {
   ActivityManager activityManager = (ActivityManager)mContext.getSystemService (Context.ACTIVITY_SERVICE);
      List<RunningTaskInfo> tasks = activityManager.getRunningTasks(Integer.MAX_VALUE);
 
      for (int i = 0; i < tasks.size(); i++) {
          Log.e("zdg",tasks.get(i).topActivity.toString());
      }
     }
 
     @Override
     public void onDestroy() {
         Log.d("slog", "onDestroy()");
         mContext = null;
         try {
    mThread.join();
   } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
         super.onDestroy();
     }
 
 }
 
         <service android:name="ServiceClass" >
                 <intent-filter>
                        <action android:name="com.example.zdgtest2.service"/>
                        <category android:name="android.intent.category.DEFAULT"/>
                 </intent-filter>
          </service>
 
 private void serviceStart()
 {
  startService(new Intent("com.example.zdgtest2.service"));
 }

결과는 에러남 ㅠㅠ

아래와 같이 변경하여 테스트

 private void serviceStart()
 {
  Intent startIntent = new Intent(this, ServiceClass.class);
  this.startService(startIntent);
  
  //startService(new Intent("com.example.zdgtest2.service"));
 }

결과가 엉망이네
이쯤에서 포기하고 인터넷 검색질.... 나같은 사람이 있었군
완전 망함

아래 검색 결과 테스트 해보고 사용하시길 바랍니다.
