I know this question already exists, but I'm not sure how to implement it in my case...
First I created an DataOutuputStream that will write in a file with .uedl extension:
private static DataOutputStream os;
public static final String BASE_PATH = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myApp/logs/"
public static void startReceiveLogs() {
if (debugBaudRate > -1) {
mReadFlag = true;
String time = TimeUtils.getCurrentTime(TimeZone.getDefault());
try {
os = new DataOutputStream(new FileOutputStream(BASE_PATH + time + "_logs.uedl"));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
mReceiveLogsThread = new Thread(new ReceiveLogsThread());
mReceiveLogsThread.start();
}
}
Here is the writing stuff:
public void run() {
byte[] rbuf = new byte[64];
while (mReadFlag) {
try {
int len = mSerial.readLog(rbuf, mSerialPortLog);
if (len > 0) {
os.write(rbuf, 0, len);
}
} catch (NullPointerException e1) {
e1.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Once this thread stops running, I'd like to compress that file at the same path.
You try this it will help for you
public boolean zipFileAtPath(String sourcePath, String toLocation) {
final int BUFFER = 2048;
File sourceFile = new File(sourcePath);
try {
BufferedInputStream origin = null;
FileOutputStream dest = new FileOutputStream(toLocation);
ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
dest));
if (sourceFile.isDirectory()) {
zipSubFolder(out, sourceFile, sourceFile.getParent().length());
} else {
byte data[] = new byte[BUFFER];
FileInputStream fi = new FileInputStream(sourcePath);
origin = new BufferedInputStream(fi, BUFFER);
ZipEntry entry = new ZipEntry(getLastPathComponent(sourcePath));
entry.setTime(sourceFile.lastModified()); // to keep modification time after unzipping
out.putNextEntry(entry);
int count;
while ((count = origin.read(data, 0, BUFFER)) != -1) {
out.write(data, 0, count);
}
}
out.close();
} catch (Exception e) {
e.printStackTrace();
return false;
}
return true;
}
private void zipSubFolder(ZipOutputStream out, File folder,
int basePathLength) throws IOException {
final int BUFFER = 2048;
File[] fileList = folder.listFiles();
BufferedInputStream origin = null;
for (File file : fileList) {
if (file.isDirectory()) {
zipSubFolder(out, file, basePathLength);
} else {
byte data[] = new byte[BUFFER];
String unmodifiedFilePath = file.getPath();
String relativePath = unmodifiedFilePath
.substring(basePathLength);
FileInputStream fi = new FileInputStream(unmodifiedFilePath);
origin = new BufferedInputStream(fi, BUFFER);
ZipEntry entry = new ZipEntry(relativePath);
entry.setTime(file.lastModified()); // to keep modification time after unzipping
out.putNextEntry(entry);
int count;
while ((count = origin.read(data, 0, BUFFER)) != -1) {
out.write(data, 0, count);
}
origin.close();
}
}
}
public String getLastPathComponent(String filePath) {
String[] segments = filePath.split("/");
if (segments.length == 0)
return "";
String lastPathComponent = segments[segments.length - 1];
return lastPathComponent;
}
