檢查它可以幫助你:

您的主要活動

package com.get_Logs; 

import java.io.BufferedReader; 
import java.io.File; 
import java.io.FileOutputStream; 
import java.io.IOException; 
import java.io.InputStreamReader; 
import java.io.OutputStreamWriter; 

import android.app.Activity; 
import android.os.Bundle; 
import android.util.Log; 
import android.widget.TextView; 

public class Get_LogsActivity extends Activity { 
    private TextView textv; 

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

     textv = (TextView)findViewById(R.id.textView1); 

     getallLogs(); 
    } 

    private void getallLogs() { 
     // TODO Auto-generated method stub 
     try { 
      Process process = Runtime.getRuntime().exec("logcat -d"); 
      BufferedReader bufferedReader = new BufferedReader(
        new InputStreamReader(process.getInputStream())); 

      StringBuilder log = new StringBuilder(); 
      String line; 
      while ((line = bufferedReader.readLine()) != null) { 
       log.append(line+"\n"); 
      } 

      File myFile = new File("/sdcard/mysdfile.doc"); 
      if (!myFile.exists()) { 
       myFile.createNewFile(); 
      } 

      Log.e("log---->", ""+log.toString()); 

      textv.setText(log.toString()); 

      FileOutputStream fOut = new FileOutputStream(myFile); 
      OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut); 
      myOutWriter.append(log.toString()); 
      myOutWriter.close(); 
      fOut.close(); 



     } catch (IOException e) { 
      Log.d("D: error generate log -->", "" + e.getMessage().toString()); 
     } 
    } 
}

是的,你可以。您可以保存日誌貓用這個命令

logcat -d -v threadtime -f /mnt/sdcard/LogCatApp.txt -s YOURTAG 

請注意,您將需要(「這裏的信息」,「YOURTAG」)添加Log.d;爲了看到的東西,你也可以保存一個完整的logcat這個

logcat -d -v threadtime -f /mnt/sdcard/LogCatApp.txt
