AsyncTaskのアンドロイドの余分なガベージコレクタ

Question

URLを使用してjsonオブジェクトをダウンロードしようとしています。そのためには、1つのAsyncTaskが作成されています。アプリケーションを起動するたびに、余分なガベージコレクタが起動します。私はどこに間違いがあるのだろうか。私はちょうどjsonレスポンスのためにAPIを呼び出そうとしている、大量のメモリ使用量のタスクを実行していない。

MainActivityコード：

public class MainActivity extends AppCompatActivity { 


public class DownloadTask extends AsyncTask<String,Void,String>{ 

    @Override 
    protected String doInBackground(String... urls) { 

     String result=null; 
     URL url; 
     HttpURLConnection httpURLConnection=null; 

     try { 
      url= new URL(urls[0]); 
      httpURLConnection= (HttpURLConnection) url.openConnection(); 
      InputStream inputStream= httpURLConnection.getInputStream(); 
      InputStreamReader inputStreamReader= new InputStreamReader(inputStream); 
      int data= inputStreamReader.read(); 
      while(data !=1){ 
       char current= (char) data; 
       result +=current; 
       data= inputStreamReader.read(); 
      } 
      return result; 

     } catch (MalformedURLException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
     return null; 
    } 

    @Override 
    protected void onPostExecute(String result) { 
     super.onPostExecute(result); 
     Log.i("webssite Content :",result); 
    } 
} 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    DownloadTask downloadTask= new DownloadTask(); 
    downloadTask.execute("http://api.openweathermap.org/data/2.5/weather?q=London&appid=5868b18238384fb4bdb3123jn9f0847cc"); 
}}

Answer 1

あなたのコード内のしばらくので、私は思う（！データ= 1）、正しいはしばらく（データでなければなりません！ = -1）。ループは無限です
