Unable to write jarlist cache file while creating android project

Question

While creating an android project in Eclipse, I get the error:

[2014-03-13 15:14:36 - appcompat_v7] WARNING: unable to write jarlist cache file C:\Users\Neelakanteshwar\AndroidFirst\appcompat_v7\bin\jarlist.cache

And appcompat_v7 folder is created along with project folder in Eclipse.

Can anyone please help me to get the solution.

Answer 1

If you go to appcompat_v7/bin folder, you'll see that file jarlist.cache doesn´t appear or is unsynchronized. You need to refresh the appcompat_v7 folder, only press F5 over that folder.

The appcompat_v7 folder is added because you use an action bar component.

Aah. To avoid a new appcompat_v7_XX folder when you are creating a new project, choose a LEVEL API 14 as Minimum Required SDK.

After that, you must modifier the AndroidManifest.xml and put the level that you need.

<uses-sdk
    android:minSdkVersion="14"   ------> change it
    android:targetSdkVersion="19" />` 

Heads up! Delete all appcompat_v7_XX. It is a bug.

With appcompat_v7, you will see that Eclipse creates two XML files:

• activity_main.xml
• fragment_main.xml

If you want to have an option to create a project in the old way only with activity_main.xml, do that:

• Make a copy of the folder "BlanckActivity" located in this path: \sdk\tools\templates\activities of an ADT previous version.

• Rename the folder as BlankActivityNoFragment, then edit the field name of the file template.xml such that, it reads name=BlankActivityNoFragment

• Copy the new folder in the same path of the new Eclipse IDE: sdk/tools/templates/activities

Now you´ll see the new template when you go to create a new project.

Remember to choose as Minimum Required SDK as API 14

Also got the same problem today.

• Install and configure all the required components.

• On the menu bar, go to: Project->Properties->Java build path.

• On the order and export tab: check all the project libraries. I checked Android 4.4.

Change Workspace path in starting Eclipse:

• from C:\Users\XXXXXXXX\workspace
• to, for example D:\My_Folder
