I need to somehow monitor the LogCat log, meaning that while my service is running I need to read the LogCat for new entries. At this moment I know only how to retrieve once the Log:
Process mLogcatProc = null;
BufferedReader reader = null;
try
{
mLogcatProc = Runtime.getRuntime().exec(new String[]
{"logcat", "-d", "ActivityManager:I *:S" });
reader = new BufferedReader(new InputStreamReader
(mLogcatProc.getInputStream()));
String line;
final StringBuilder log = new StringBuilder();
String separator = System.getProperty("line.separator");
while ((line = reader.readLine()) != null)
{
log.append(line);
log.append(separator);
}
If I remove the -d option it will not exit but also it will not either work. So how can I modify the bellow code in order to continuously read new entries from LogCat?
This is how I did it, using Jiahao Liu's suggestion:
ReadThread thread;
public void startRecordingLogs()
{
if(thread == null || !thread.isAlive())
{
ReadThread thread = new ReadThread();
thread.start();
}
}
public String stopRecordingLogs()
{
String results = thread.stopLogging();
return results;
}
private class ReadThread extends Thread{
String results;
Process process;
Object lockObject = new Object();
public void run(){
synchronized(lockObject)
{
process = Runtime.getRuntime().exec("logcat -v time");
reader = new BufferedReader(new InputStreamReader (process.getInputStream()));
String line;
final StringBuilder log = new StringBuilder();
String separator = System.getProperty("line.separator");
while ((line = reader.readLine()) != null)
{
log.append(line);
log.append(separator);
}
}
results = log.toString();
}
public String stopLogging()
{
process.destroy();
synchronized(lockObject)
{
return results;
}
}
}
