파일 복사 후 성공 메시지 표시

Question

저는 Android 개발에 처음으로 익숙해 졌으므로 기본 응용 프로그램으로 시작할 것이라고 생각했습니다. 버튼을 누르면 코드에 기록 된 위치로 파일을 복사합니다 (아래 코드 참조). 설치 버튼을 누르면 파일이 그 위치에 복사 될 때 "파일을 복사하는 동안 성공적으로 설치되었거나 오류가 발생했습니다"라는 토스트 메시지가 나타납니다. 어떻게 구현할 수 있습니까?

public class TrialActivity extends Activity { 

private ProgressDialog progressDialog; 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 


    runDialog(5); 
} 

private void runDialog(final int seconds) 
{ 
    progressDialog = ProgressDialog.show(this, "Please Wait...", "unpacking patch in progress"); 

    new Thread(new Runnable(){ 
     public void run(){ 
      try { 
       Thread.sleep(seconds * 1000); 
       progressDialog.dismiss(); 
      } catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 
     } 
    }).start(); 

    ((Button)findViewById(R.id.button1)).setOnClickListener(new View.OnClickListener() 
    { 
     public void onClick(View paramView) 
     { 

     } 

    { 

       InputStream in = null; 
       OutputStream out = null; 
    String filename="savegame.bin";   
    try {  

       in = getResources().openRawResource(R.raw.savegame); 
       out = new FileOutputStream("/sdcard/Android/data/files/" + filename); 
       copyFile(in, out); 
       in.close(); 
       in = null; 
       out.flush(); 
       out.close(); 
       out = null; 
       } catch(Exception e) { 
        Log.e("tag", e.getMessage()); 
       }  

     } 
     private void copyFile(InputStream in, OutputStream out) throws IOException { 
      byte[] buffer = new byte[1024]; 
      int read; 
      while((read = in.read(buffer)) != -1){ 
      out.write(buffer, 0, read); 


      } 
     } 
     } 
    ); 
    } 

}

사용 다음 코드 :

private class AsyncTaskDialog extends AsyncTask<Void, Void, Void> { 
    Toast toastSuccess; 


    boolean flagSuccessCopy =false; 
      protected void onPreExecute() { 
       super.onPreExecute(); 


       } 
      } 

      protected Boolean doInBackground(Void... params) { 
       copyFiles(); 
       return null; 
      } 

      @Override 
      protected void onPostExecute(Boolean result) { 
       super.onPostExecute(result); 

       if (getActivity() != null) { 
       if(flagSuccessCopy){ 
        toastSuccess = Toast.makeText(context, "Success", duration); 
       }else{ 
         toastSuccess = Toast.makeText(context, "Error", duration); 
       } 
       toast.show();    
      } 
     }
