在测试调用外部提供的ContentProvider时候报一下错误：
java.lang.SecurityException: Permission Denial: opening provider com.example.onehw.BookProvider from ProcessRecord{b2f1b230 8449:com.example.adtest/u0a53} (pid=8449, uid=10053) that is not exported from uid 10052

是权限的问题，在AndroidManifest.xml 加上红色部分就解决
<provider android:name="BookProvider" android:authorities="com.example.provides.bookprovider" android:exported="true" />
java.lang.SecurityException: Permission Denial: opening provider
