Please see the logs as this way,
Log.e("ApiUrl = ", "MyApiUrl") (error)
Log.w("ApiUrl = ", "MyApiUrl") (warning)
Log.i("ApiUrl = ", "MyApiUrl") (information)
Log.d("ApiUrl = ", "MyApiUrl") (debug)
Log.v("ApiUrl = ", "MyApiUrl") (verbose)
The Tag is just used to easily find your output, because the Output of LogCat can be sometimes very long. You can define somewhere in your class:
private static final String TAG = "myApp";
and use it when debugging
Log.v(TAG, "did something");
You can apply as well a Filter to only search for the tag.
String one = object.getdata();
Log.d(one,"");
import android.util.Log;
and then
Log.i("the your message will go here");
Use android.util.Log
and the static methods defined there (e.g., e()
, w()
).
Recently I found this approach to writing logs in android, which I think is super awesome.
public static final boolean FORCED_LOGGING = true;
private static final int CALLER_STACK_INDEX = 3;
public static void showLogs(String message) {
if (FORCED_LOGGING) {
StackTraceElement caller = Thread.currentThread().getStackTrace()[CALLER_STACK_INDEX];
String fullClassName = caller.getClassName();
String className = fullClassName.substring(fullClassName.lastIndexOf('.') + 1);
String methodName = caller.getMethodName();
int lineNumber = caller.getLineNumber();
Log.i("*** " + className + "." + methodName + "():" + lineNumber + "\n" , message);
}
}
You can use my libary called RDALogger. Here is github link.
With this library, you can log your message with method name/class name/line number and anchor link. With this link, when you click log, screen goes to this line of code.
To use library, you must do implementations below.
in root level gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
in app level gradle
dependencies {
implementation 'com.github.ardakaplan:RDALogger:1.0.0'
}
For initializing library, you should start like this (in Application.class or before first use)
RDALogger.start("TAG NAME").enableLogging(true);
And than you can log whatever you want;
RDALogger.info("info");
RDALogger.debug("debug");
RDALogger.verbose("verbose");
RDALogger.warn("warn");
RDALogger.error("error");
RDALogger.error(new Throwable());
RDALogger.error("error", new Throwable());
And finally output shows you all you want (class name, method name, anchor link, message)
