Problem
After you update ADT to 22.6.0, you create a new setup project, and the contents of appcompat_v7 appear. and create a new content that will appear. In fact, Appcompat_v7 is Google's own a compatibility package, a support library, to allow more than 2.1 full use of the 4.0 version of the interface.
Solve
- First solve the project after the completion of the APPCOMPAT_V7 package error. The test package has a red warning issue. Click "Project" on the menu bar, select "Clean", then "OK", and when clean is complete, you will find the APPCOMPAT_V7 package error. The problem with the red warning in the test package has been resolved, except that the test package has a yellow warning, just because the import class in Test's Java file is not being used, so it is completely out of control. If it does not work, then right-click Appcompat_v7 package, select Properties, click "Android", if the library under the "Is Library" box is not checked, tick, click "OK", then follow the above steps to perform "clean" Operation.
- After the APPCOMPAT_V7 package is deleted, the test project has various errors, stating that the test project is dependent on the APPCOMPAT_V7 package, so this APPCOMPAT_V7 package cannot be deleted. Then you don't have to take care of the bag.
- If you don't want the APPCOMPAT_V7 package to appear. Since the APPCOMPAT_V7 package is a support library that allows more than 2.1 to use the 4.0 version of the interface, then when we build the project, we select the Minimum SDK above Android4.0, and the Compatibility Pack will not appear.
