• Stream the logcat output to

Answer 1

I repost my answer here so @JPM and others can see... The code basically just execute the logcat command and then build the log from the input stream.

final StringBuilder log = new StringBuilder();
try {        
    ArrayList commandLine = new ArrayList();
    commandLine.add("logcat");
    commandLine.add("-d");
    ArrayList arguments = ((params != null) && (params.length > 0)) ? params[0] : null;
    if (null != arguments){
        commandLine.addAll(arguments);
    }

    Process process = Runtime.getRuntime().exec(commandLine.toArray(new String[0]));
    BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(process.getInputStream()));

    String line;
    while ((line = bufferedReader.readLine()) != null){ 
        log.append(line);
        log.append(LINE_SEPARATOR); 
    }
} 
catch (IOException e){
        //
} 

return log;
