Android Debugging

Two great ways to debug better. Happy testing.

1. In Android Studio add font color to logcat.

• How to add color font to logcat follow the below steps:

1.  Open Android Studio
2. Preferences -> Editor -> Colors & Fonts -> Android Logcat.
3. Click button ‘Save As’, and name your new Scheme. (uncheck ‘Use inherited attributes’)
4. In the right side select a color for each component: Assert, Debug, Error, Info, Verbose, Warning.

2. Add color to terminal adb logcat.

• Take a look at this tool from Jake Wharton pidcast:

Easy to use.

Install: $brew install pidcat

Use: $adb logcat -v brief | pidcat com.myPackage.Name 

Third party tool optioon: Mac tool LogRabbit  http://lograbbit.com $10


Let me know if you have any questions.

Update Android SDK and Tools from terminal

1. Open Terminal and type below commands.

Opens Android SDK Manager UI. (same as
$android

Software available to update
$android list sdk -a

Install software
$android update sdk -a -u -t #
$enter 'y' to accept license

-----------------------------------------
Example
$android list sdk -a

outputs:
140- GPU Debugging tools, revision 3.1
141- GPU Debugging tools, revision 1.0.3
142- Android Support Repository, revision 34

We want to update "Android Support Repository, revision 34".
we need to use below command:
$android update sdk -a -u -t 142
$enter 'y' to accept license 
Done command installs Android Support Repository, revision 34 :)

 

In Android Studio 2.2 gradlew command can donwload android.sdk dependencies

For more info watch video from GoogleIO 2016 What's new in Android Development tools (min 11:55-12:15)

Gradle Build System release notes

Add to gradle.properties:
android.builder.sdkDownload=true

According to this post:
Command will only download android sdk, it will not download google service, repository etc..

Kotlin Tutorials

Kotlin could be the future of Android Development :)

Book: https://leanpub.com/kotlin-for-android-developers/
ebook sample: file:///Users/andres/Downloads/kotlin-for-android-developers-sample.pdf

Testing:
*** read http://blog.wittchen.biz.pl/hello-kotlin/
It’s also worth mentioning that there is a project created in Kotlin by JetBrains called Spek which is a specification framework for the JVM and you can use it for writing unit tests in the JVM projects in order to get human readable output.
