Collect All Log.d From Class And Save It Into Sdcard

Hey is it possible in Android to collect all Log.d from one class and keep on appending it and save it into SDCard ? For example : Class Android { private final static String

Solution 1:

You can get all logs with the logcat command. You can try something like:

publicstaticvoidprintLog(Context context){
    Stringfilename= context.getExternalFilesDir(null).getPath() + File.separator + "my_app.log";
    Stringcommand="logcat -d *:V";

    Log.d(TAG, "command: " + command);

    try{
        Processprocess= Runtime.getRuntime().exec(command);

        BufferedReaderin=newBufferedReader(newInputStreamReader(process.getInputStream()));
        Stringline=null;
        try{
            Filefile=newFile(filename);
            file.createNewFile();
            FileWriterwriter=newFileWriter(file);
            while((line = in.readLine()) != null){
                writer.write(line + "\n");
            }
            writer.flush();
            writer.close();
        }
        catch(IOException e){
            e.printStackTrace();
        }
    }
    catch(IOException e){
        e.printStackTrace();
    }
}

You can get more information about logcat here: http://developer.android.com/tools/help/logcat.html

Solution 2:

You can override the Log class and do that yourself. But is it really required for your purposes?

Solution 3:

no, Log.* methods write to the console, however you can use Logger http://developer.android.com/reference/java/util/logging/Logger.html and a FileHandler

Solution 4:

If you want to add logs with tag name and

logcat -s <Tagname>

Is not working for you then you can do this trick

//... Brtle 's code..(accepted one )
    file.createNewFile();
       FileWriterwriter=newFileWriter(file);
         while((line = in.readLine()) != null){
             if(line.contains("TAG_NAME")){ // Trick :-)
                writer.write(line + "\n");
               }
             }
