Simple android logger (2020)
Java version:
Kotlin version:
- Add the dependency from jCenter to your app's (not project) build.gradle file:
repositories {
jcenter()
}
dependencies {
implementation 'net.alexandroid.utils:mylogkt:1.13'
}- Consider adding following proguard rule:
# Remove all log* methods from prpject
-assumenosideeffects class net.alexandroid.utils.mylogkt.MyLogKtKt { *; }
# Remove specific logger methods
-assumenosideeffects class net.alexandroid.utils.mylogkt.MyLogKtKt {
public static *** logD$default(...);
public static *** logW$default(...);
}- Next (All the settings below are optional):
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
// Kotlin from Kotlin (Optional, to allow isPackageNameVisible = true)
MyLogKt.packageName = packageName
MyLogKt.isLogsShown = BuildConfig.DEBUG
MyLogKt.tag = "STATIC CUSTOM TAG"
// Other Kotlin version configurations
MyLogKt.packageName = ""
MyLogKt.isLogsShown = true
MyLogKt.isThreadNameVisible = false
MyLogKt.isTimeVisible = true
MyLogKt.isPackageNameVisible = false
MyLogKt.isClassNameVisible = true
MyLogKt.isMethodNameVisible = true
MyLogKt.isLengthShouldWrap = true
MyLogKt.classNameLength = 15
MyLogKt.packageAndClassNameLength = 35
MyLogKt.methodNameLength = 15
MyLogKt.threadNameLength = 6
MyLogKt.timeFormat = "HH:mm:ss.SSS"
}
}- Also don't forget to add: android:name=".MyApplication" at your application tag in AndroidManifest.xml
<application
android:name=".MyApplication"
...> logD("Empty 1")
logI("Empty 2")
logW("Empty 3")
logE("Empty 4")
logV("Empty 5")
// Same functions
debug("Empty 1")
info("Empty 2")
warn("Empty 3")
error("Empty 4")
verbose("Empty 5")
logD("Custom tag example 1", "CustomTag1")
logE("Show Exception", t = NullPointerException())
