I want to use Grid Layout, but get the following error:
Error: No resource identifier found for attribute 'columnCount' in package 'android'
Is this because my API level is 9?
Does Grid Layout REALLY need API level 14?
(I use Version: 8.0.1.v201012062107-82219)
- If yes, what should I do? Please explain this step by step.
- If no, so what's the reason? I'm doing exactly the same as the example!
Here are the steps i spent to solve my problem:
To use GridLayout, i figured out many things should be upgraded.
- i had "jdk 7" installed on my system, so didn't need to upgrade it.
- i downloaded "installer_r20-windows.exe" and ran it.
- i downloaded "platforms" which contains "android-14", and copied it into android-sdk folder. (mine is: C:\ Android\android-sdk)
- i downloaded "system images" which contains "armeabi-v7a", and copied it into my sdk folder.
- i downloaded "platform-tools_r13-windows" and copied it into SDK folder.
- Then i found out also my eclipse is old, thus downloaded it's latest version, "eclipse 4.2_juno" (27 june 2012)
- i downloaded "Eclipse-plugins-ADT-20.0.zip". Then into eclipse: Help > Install New Software > Add > Archive > Eclipse-plugins-ADT-20.0.zip. Then select "Developer Tools" > click next > accept > click finish > restart eclipse.
- Again in eclipse: Window> Preferences > Android > SDK Location: path where my android-sdk folder exists.(e.g. mine is "C:\Android\android-sdk") > Apply > select "Android 4.0" > click OK.
- Then i created new AVD, from: eclipse > Window > AVD Manager > New..
- Finally, into sdk folder i created a new folder named "extras", into it another new folder named "android", into it another new folder named "support".
- Then i extracted content of "support_r09.zip" (which have downloaded it).
Now everything is ok..
Thanks to everybody helped me in this post (viperbone, Doomsknight, Matthieu, MemLeak,Jeroen).
GridLayout needs API 14
You can create a Layout for the other android versions -> Adapt layout to Android platform or API level
Yes, the GridLayout is only available if you run it on devices with API Level 14 or higher.
Not sure what that version 8.0.1.... is ? Definitely not the Android version.
If you plan to run your application on anything earlier than Ice Cream Sandwich I am afraid you have to use something else than that Layout. TableLayout maybe ? Or check this question
MORE (from comments):
Either you are ok with your app to run only on ICS or above (so somebody with a phone with Gingerbread will not be able to run it for example).
If yes, then:
- Download the latest Android SDK
- Set targetSDKversion="14" in your manifest
And this error should go away.
If no, then you CANNOT use GridLayout. You have a few options to replace it:
- Download the library from : https://github.com/dlew/android-gridlayout and use that
- Use some other layout (like TableLayout or LinearLayouts)
In your manifest use:
<uses-sdk minSdkVersion="14" />
However, this will mean that any device running an Android API below 14 will not be able to use your app
