I am developing an application that uses the libraries appcompat v7 and support-v4. The application works correctly and its main theme is derived from Theme.AppCompat.

Problems arise when I try to add any module (android library project) to the main project: I always get an IllegalStateException.

At the moment the project library is completely empty: no Java classes or XML resources, there is only the file AndroidManifest:

MyLibrary AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.viewpagerindicator"
    android:versionCode="1"
    android:versionName="1.0">

    <uses-sdk
        android:minSdkVersion="7"
        android:targetSdkVersion="18" />
    <application />
</manifest>

I also tried to add the theme Theme.AppCompat to the Application section of MyLibrary:

<?xml version="1.0" encoding="utf-8"?>
[...]
    <application android:theme="@style/Theme.AppCompat" />
</manifest>

But the result is always the same exception:

我不知道到底发生了什么，但我想在资源合并过程中存在一些问题。

我会尝试从应用程序中删除这些依赖项build.gradle

compile 'com.android.support:appcompat-v7:+'
compile 'com.android.support:support-v4:+'

把它们留在图书馆里build.gradle。
