APPCOMPAT_V7 Error in Android6.0

Updated ANDROIDSDK after a variety of errors, a new project will be attached to a appcompat_v7, you just know that this is a compatibility package can be, the specific features can see the relevant introduction, in fact, nothing special is to be compatible with the lower version of the chant,

However, this leads to a variety of errors, and the following are the errors that occur:

After several hours of adjusting supervised, a variety of articles that need to restart Eclipse, in fact, it doesn't matter, important or configuration, the following is the solution:

The first step: select Appcompat_v7-->properties-->android--> to select the highest API version and make sure that the is library in the library is selected, which means to ensure that the project is a class library project Cannot be started.

Step two: After determining the first step, choose Project-->clean, and you can see that the APPCOMPAT_V7 error has disappeared;

The third step: The second step of apply after your project is still an error, will show you referenced in the class library style error, this is because the API version of your new project is too low to recognize the class library related properties, modify the properties of your current project file

I changed from 15 to 23:

Fourth step: Although setting the project properties target setting is API23 version, the USE-SDK in the manifest file is still the lowest SDK version number you expect, and the target version number does not affect the run because I tested it, Want to create a Android6.0 simulator there is no matching CPU, my host is Interl core 7 can not do it.

After the last step, clean it, the problem is guaranteed to be resolved. Because I just learned a few days, I hope that we have a lot of advice, but also hope that their own detours, can create a new continent for others
