android logcat不會每次都讀取日誌

Question

我嘗試讀取我應用中的所有android logcat記錄並將它們顯示在列表視圖中。 在我的代碼有時我可以閱讀日誌，但somtimes不能。 如果我打開logcatactivity我可以讀取所有的日誌，但然後我不能讀

oReadLogTask = new ReadLogTask(); 
    oReadLogTask.execute(); 

private class ReadLogTask extends AsyncTask<Integer, Integer, Boolean> 
{ 
    private ProgressDialog oProgressDialog; 

    @Override 
    protected void onPreExecute() 
    { 
     oLogVeriler = new ArrayList<LogCatVeri>(); 

     oProgressDialog = ProgressDialog.show(LogCat.this, "", "Log loading..."); 
     oProgressDialog.show(); 
     oProgressDialog.setCancelable(true); 
     oProgressDialog.setOnCancelListener(new DialogInterface.OnCancelListener() 
     { 
      public void onCancel(DialogInterface dialog) 
      { 
       oSayfaYukleTask.cancel(true); 
      } 
     }); 
    } 

    protected void onProgressUpdate(Integer... progUpdate) 
    { 
     oProgressDialog.setMessage("Log load... " + progUpdate[0] + "/" + progUpdate[1]); 
    } 

    @Override 
    protected Boolean doInBackground(Integer... params) 
    { 
     if (params == null) 
     { 
      return false; 
     } 
     try 
     { 
      List<String> progs = new ArrayList<String>(); 
      progs.add("logcat"); 
      progs.add("-v");     
      progs.add("time"); 
      progs.add("*:" + "V"); 
      logcatProc = Runtime.getRuntime().exec(progs.toArray(new String[0])); 
      mReader = new BufferedReader(new InputStreamReader(logcatProc.getInputStream()), 1024); 
      int LineAdetTum = 0; 
      int LineAdetAranan = 0; 
      String LogTagAdKucuk = LogTagAd.toLowerCase(); 
      String line; 
      while ((line = mReader.readLine()) != null) 
      { 
       LineAdetTum++; 
       publishProgress(LineAdetAranan, LineAdetTum); 

       if (!line.toLowerCase().contains(LogTagAdKucuk)) 
       { 
        boolean ready = mReader.ready(); 
        if (!ready) 
         break; 
        else 
         continue; 
       } 
       else 
       { 
        boolean ready = mReader.ready(); 
        if (!ready) 
         break; 
       } 

       LineAdetAranan++; 
       publishProgress(LineAdetAranan, LineAdetTum); 

       LogCatVeri oLogVeri = new LogCatVeri(line, LogTagAdKucuk, LogTagAd); 
       oLogVeriler.add(oLogVeri); 
      } 
      return true; 
     } 
     catch (IOException ex) 
     { 
      Log.e("alogcat", "Log read err" + ex.getMessage(), ex); 
      return false; 
     } 
     catch (Exception ex) 
     { 
      Log.e("alogcat", "Log read err2" + ex.getMessage(), ex);

     } 
     finally 
     { 
      if (logcatProc != null) 
      { 
       logcatProc.destroy(); 
       logcatProc = null; 
      } 
      if (mReader != null)

      } 
     } 
    } 

    @Override

     if (result) 
      ShowRes(); 
     else 
      Toast.makeText(getApplicationContext(), "Log rec err", Toast.LENGTH_LONG).show(); 

     oProgressDialog.dismiss(); 
    }

public void ShowRes() 
{ 
    mLogEntryAdapter = new LogCatAdapter(this, R.layout.lc_log_cat_list, oLogVeriler); 
    mLogList.setAdapter(mLogEntryAdapter); 
}

試試這個。 只看完所有日誌到目前爲止

Log.e("Log", " 111"); 
Log.e("Log", "222"); 

    try 
    { 
     // read 
     Process process = Runtime.getRuntime().exec("logcat -d *:e"); 
     BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream())); 

     StringBuilder log=new StringBuilder(); 
     String line = ""; 
     while ((line = bufferedReader.readLine()) != null) 
     { 
      log.append(line); 
     } 
     TextView tv = (TextView)findViewById(R.id.textView1); 
     tv.setText(log.toString()); 

// clear 
     Runtime.getRuntime().exec(new String[]{"logcat", "-c"}); 
    } 
    catch (IOException e) 
    { 
    }
