İşte kullandığım kod - 4000 sınırında satırları keserken, aynı zamanda satırın ortalarında değil de yeni satırlarda satırı kesiyor. Günlük dosyasının okunmasını kolaylaştırır.
Kullanım:
Logger.debugEntire("....");
Uygulama:
package ...;
import android.util.Log;
import java.util.Arrays;
public class Logger {
private static final String LOG_TAG = "MyRockingApp";
/** @see <a href="http://stackoverflow.com/a/8899735" /> */
private static final int ENTRY_MAX_LEN = 4000;
/**
* @param args If the last argument is an exception than it prints out the stack trace, and there should be no {}
* or %s placeholder for it.
*/
public static void d(String message, Object... args) {
log(Log.DEBUG, false, message, args);
}
/**
* Display the entire message, showing multiple lines if there are over 4000 characters rather than truncating it.
