hello everyone, thanks for your suggestions. i did copy the files to the path so maybe i'm going to follow +Deepanshu Gupta 's instructions. i'll try it later because my another PC's cannot be used right now. i'll confirm it later. thanks.

The Graphical Layout Editor should issue a warning to inform users that the feature is extremely unstable and may cause Android Studio to become unresponsive resulting in loss of work. Thoughts?

3 consecutive days with crashes + lost work. You think I would learn. It works fine initially, performance degrades over time....until it eventually blows up. Tor n team, you guys do a great job! This issue has been around forever, when will it get prioritized? Can I help? haha

Ask yourself : if people came to you with that little information, would you even be able to understand their question ? If the answer is no, you should probably rephrase ...

Red flag: You're using Android Studio 1.0.1 and a lot of work has been done between that and Android Studio 1.2. Upgrading / installing latest should fix you.

Next: I wonder if you have a missing / incomplete SDK install... Can you navigate to your Android SDK and check that you have <SDK>/tools/emulator.exe? If so, go to File -> Project Structure and make sure to set your SDK location. If emulator.exe is missing, download the latest SDK from here:

Hi everyone,

I was wondering if there is any way to get Android Studio to render fonts in the layout preview window?

In recent versions of the SDK (not sure if API 22 or M Preview) you can also see custom fonts in the preview editor. (see this answer from above stack overflow post posted by Pablo:

Dear Friends, can you please let me know the tool you use to show your app on Android phone in Windows PC? I did some search heard about Mobizon and Droid etc.. But would like to know which one is the best... Criteria - I need this for a demo one time, so looking for a free tool. Thanks in advance. And posting here as I believe screen cast should help developer explain the app. Sorry if it is a wrong forum. Regards

Does anyone else find it annoying/strange that (on OS X) Command Up/Down does not scroll to top/bottom like in most other editors?

I've since edited the Keymap, but shouldn't this be the default?

I apologize if this is already posted. I found this helpful.

I was tired of using USB cable to debug apps. I searched on google and found a way to debug apps without USB.

Screenshot itself is pretty explanatory.

P.S. To find your device IP address, head to
1. Settings > About > Status > IP address
2. WiFi > Advanced > IP address

you might need to enable "ADB over network" option from Developer options if any.

How can I set a different test and compile output directories for the Android gradle plugin?

I have a gradle task plugin that needs to do some class instrumentation on the compiled test classes and provide its output directory to the android test execution task.


my plugin task input directory = android test compile task output directory
android test input directory = my plugin task output directory

Android Test + Espresso + JaCoCo
If you try to run Espresso tests on device and at the same time grab the code coverage information, than your are looking on the right topic... Its all about this.

Unfortunately JaCoCo + Espresso does not work for everyone. 

Quick search will reveal a planty of reported issues and mostly no working solutions. I also ignore this problem till Michenux contact me and ask for help. (Good for us all in Sweden is a "red date" in calendar and I have some free time)

The issue and why it exists?
AndroidTest configuration produce a special APK. Inside it included source code of the original binary, libraries and instrumentation. Problem is that Android Dalvik is not 100% compatible JVM, so it does not support JVM javaagents (its the way how originally JaCoCo/Emma should be used with Java). So everything we need is inside the APK, but we cannot able to run it properly.           

That is why inside Android should be used a special way for code coverage instruments. Its known as a "JaCoCo offline mode". In two words - this is a pre-processing of *.class files and embedding into them of special Jacoco method, that executed from class constructor. So when you execute the tests, Jacoco is able to identify that and collect runtime information.


Android build system should do that all, but looks like it fails at the current moment. 

Steps that build system should do:
1) download and install dependency JaCoCo library - DONE
2) include JaCoCo Agent into APK - DONE
3) create classes with enabled jacoco (offline mode) - DONE
4) replace original files by "jacoco enabled" - NOT WORKING
5) define coverage result output path - NOT WORKING
6) run tests - DONE
7) PULL coverage file from device - NO
8) Generate HTML coverage report - NO

The Solution
all in this Gradle file:

Step #1: use the latest version of JaCoCo ("")
Step #2: Destination path can be defined by resource file - (~/src/androidTest/resources/ [for alternative look inside the org.michenux.espressotestcoverageapp.AndroidJacocoTestRunner class]

> #destfile =/sdcard/
> destfile=/data/data/{}/

Step #3: Modify build sequence. Place own customization tasks between "preDex${flavor}${buildType}AndroidTest" and "dex${flavor}${buildType}AndroidTest". I name them: "fixJacocoAgentAndroidTest${flavor}${buildType}" and "fixJacocoAndroidTest${flavor}${buildType}"

Step #3.1:
"fixJacocoAgentAndroidTest${flavor}${buildType}"  - this task include jacocoagent.jar into final binary (simply copy JAR into "${project.buildDir}/intermediates/pre-dexed/androidTest/${flavor}/${buildType}" folder). After that other tasks will use it during the compilation. 

Step #3.2:
"fixJacocoAndroidTest${flavor}${buildType}" - copy "jacoco enabled" classes on top of old classes.

Step #4:
Run the project. Inside the app folder you will find a "" with non-zero size. 


What's left:
- PULL file from device to PC (adb pull *)
- create JaCoCo HTML report (I did this in my older posts, just use the gradle from them, it will work if you pull coverage file into project build folder)

P.S. latest android gradle plugin (1.3-beta3) looks like partly resolves the issues

Oleksandr, thanks for your reply - I'm trying this now. The answer to your question - we didn't manage to run the tests using the app source so decided to go with app.apk, and still want to have the coverage for these tests
