In my libs folder i have added three jar files -> support design, supportV4, supportV7-appcompact, gcm(i have removed libraries in appcompact project library )

As well in my manifest i have changed my app theme to android:theme="@style/Theme.AppCompat" changed activity to AppCompatActivity, Now when i try to run my application it always through an exception. Kindly help me to fix this issue Searched through google but all the solution is for Android-Studio i am using eclipse

Thanks in advance

回答1:

import android-support-* jar files in libs, may causes error.

each library is android-project structure, jar file is not contain android-project structure (res, assets, etc).

import libraries projects and add reference.

check your project settings.

1. import 'android-support-v7-appcompat library' as project?
2. clean android-support-v7-appcompat library and your project.

3. check your project, referencing appcompat library.

4. check build path

if you still facing error, please comment.
