Live Template not working in Kotlin

Question

Hope you have worked with Live Templates which is given by Android by default.

Like:

Generate debug log statement: "logd"+TAB Generate error log statement: "loge"+TAB Generate info log statement: "logi"+TAB Generate TAG declaration: "logt"+TAB Generate parameter logging: "logm"+TAB Generate method return log: "logr"+TAB 

Which it is not available in KOTLIN?

Is it not available in Android Studio 3.0 Canary Version?

Answer 1

Here is the step-by-step guide:

Firstly, Copy and paste AndroidLog templates to Kotlin (Just select them and use CMD+C, CMD+V (or Ctrl+C, Ctrl+V)
Secondly, You have to adjust them manually:

1. logd (loge, logv and others) Select the logd item and press "Edit variables"

Change expression to: kotlinMethodName()

Also, remove ; from the end of the template, as you don't need it in Kotlin.

Now your method name will be shown correctly

2. logt

This one is a bit trickier.
Solution 1: TAG = class name.

Template text :

private val TAG = "$className$" 

Edit variables -> Expression:

groovyScript("_1.take(Math.min(23, _1.length()));", kotlinClassName()) 

Solution 2: TAG = file name (can be used inside Companion)

Template text :

private const val TAG = "$className$" 

or:

companion object {     private const val TAG = "$className$" } 

Edit variables -> Expression:

groovyScript("_1.take(Math.min(23, _1.length()));", fileNameWithoutExtension()) 

Answer 2

Yet not added log template in Kotlin Live templates section in Android Studio.

Settings -> Editor -> Live Templates -> Kotlin for kotlin templates.

Settings -> Editor -> Live Templates -> AndroidLog for AndroidLog templates

.

So you can't get the same AndroidLog templates in Kotlin code.

So now Question is How to use same Log Functions using templates in Kotlin?

Ans: You can add same Log templates (AndroidLog Templates) in Kotlin Templates section in Android studio as below example.

Then It will be available in your Kotlin code!

I hope in this way you can get an advantage of Log functions templates in Kotlin.
