Android-Studio upgraded from 0.1.9 to 0.2.0 causin

问题:

My current project had been building with Gradle just fine, since I created it (about a month ago), after acquiring Android-Studio. [I installed some earlier updates to Android-Studio, and had no problems with those.]

But, today, after I upgraded Android-Studio's newest update to a "July 11th" build, going from version 0.1.9 to 0.2.0, my project started complaining that Gradle now needs to be at minimum of 0.5.0. (My project was asking for Gradle 0.4, and this new Studio upgrade flagged my Gradle build and stated it would NOW need this new higher minimum of Gradle.

So, what I'm unclear about: I've been assuming Gradle is PART of (bundled with) Android Studio.

Do I now need to get a newer Gradle, as a separate product/update?

I'm confused!!!

EDIT: (This is happening under Windows-7).

Solution for me without reinstalling or creating a new project:

Step 1: Change line in build.gradle from:

dependencies {
    classpath 'com.android.tools.build:gradle:0.4'
}

to

dependencies {
    classpath 'com.android.tools.build:gradle:0.5.+'
}

Note: for newer versions of gradle you may need to change it to 0.6.+ instead.

Step 2: In the <YourProject>.iml file, delete the entire<component name="FacetManager">[...]</component> tag.

Step 3 (Maybe not necessary): In the Android SDK manager, install (if not already installed) Android Support Repository under Extras.

Basically if you follow the issues in this link for 0.2 you'll likely get yourself fixed, I had the same problems with 0.2

回答3:

Ok, I finally resolved this, by completely de-installing Android-Studio, and then installing the latest (0.2.0) from scratch.

EDIT: I also had to use the Android SDK-Manager, and install the component in the 'Extras' section called the Android Support Repository (as mentioned elsewhere).

Note: This does NOT fix my old existing project...that one still will not build, as indicated above.

But, it DOES solve the issue of now being able to at least create NEW projects going forward, that build ok using 'Gradle'. (So, basically, I re-created my proj from scratch under a new name, and copied all my code and project xml-files, etc, from the old project, into the newly-created one.)

[As an aside: I've got an idea, Google! Why don't you refer to versions of Android-Studio using numbers like 0.1.9 and 0.2.0, but then when users click on 'About' menu item, or search elsewhere for what version they are running, you could baffle them with crap like 'the July 11th build' or aka, some build number with 6 or 8 digits of numbering, and make them wonder what version they actually have! That will keep the developers guessing...really will sort the wheat from the chaff, etc.]

For example, I originally installed a kit named: android-studio-bundle-130.687321-windows.exe

Today, I got the "0.2.0" kit???, and it has a name like: android-studio-bundle-130.737825-windows.exe

Yep, this version #ing system is about as clear as mud.
Why bother with the illusion of version#s, when you don't use them!!!???

Gradle should be updated already, you just need to let your previous projects know gradle has been updated.

Source

Edit your build.gradle file to show this:

dependencies {
classpath 'com.android.tools.build:gradle:0.5.+'
}

This should only be required for projects created with the previous version of Android Studio. New projects you create will have that by default.

回答5:

now you can use the last 1.0.0-rc1 this way :

classpath 'com.android.tools.build:gradle:1.0.0-rc1'

This needs Gradle 2.0 if you don't have it Android Studio will ask you to download it

回答6:

if you get this error

Gradle: 
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'assemble' not found in root project 'MyProject'.
* Try:
Run gradle tasks to get a list of available tasks.

You need to edit your Projects .iml file. not the one under src. the one that is like myappProject.iml' delete the whole component name = facetmanager

<module external.system.id="GRADLE" type="JAVA_MODULE" version="4">
<component name="FacetManager">
...remove this element and everything inside such as <facet> elements...
</component>
<component name="NewModuleRootManager" inherit-compiler-output="true">
...keep this part...
</component

For people who have this problem today(to example to switch from 2.8.0 to 2.10.0), move to file gradle-wrapper.properties and set distributionUrl with the value you need. distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip

I changed 2.8.0 to 2.10.0 and dont forget to Sync after
