I use android studio with sdk v24. When I create my new application and just go to the MainActivity.jar It shows me many codes red? Here it is that I'm talking about:(screen shot)

I'm really confused. How can I fix these errors?

NOTE: my sdk is up to date (as you see here: https://dl.dropboxusercontent.com/u/100174344/Screenshot%202015-01-06%2008.22.28.png ) and I've added this code to my build.gradle(Module: app) :

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3' }

EDIT: I'm sorry I create a new project and still it show me the codes, red but I can run it in AVD. what's the problem?

You want To add android.support.v7.jar not added that y i think this error occurs.

add this in your project property file

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.+'
}

  • maybe. but when I write the import code manually I can write it up to here: "import import android.support.v7" but after that, it's going to crash – Mohammad Tahvildary Jan 06 '15 at 04:48
  • no first you orgnize import in studio. and then You can not see the v7 jar classes. measns it can not reference to your v7.jar – Dilavar Malek Jan 06 '15 at 04:51

Did you added android.support.v7.jar? Just make sure your sdk is updated and you've added android.support.v7.jar. Also check the dependencies.

You need to add appcompat v7 dependencies to the app gradle file. Ensure build.gradle(Module : app) is having the dependency. If not available then add and sync the project It should be like-

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.+'
}

  • You don't need to add android.support.v7.jar in the libs folder.Remove it and re sync. Post the Error Message you are getting. – Sanjeet A Jan 06 '15 at 05:39

I found the problem I don't know why but when I changed the theme by this structure the issue is up.
