报错：

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed with multiple errors, see logs

代码：

  <provider
            android:name="android.support.v4.content.FileProvider"
            android:authorities="aly.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />

解决：由于多个lib库中定义类相同所以冲突，集成FileProvider重写个类即可。

public class MyFileProvider extends FileProvider {

}

        <provider
            android:name=".fileProvider.MyFileProvider"
            android:authorities="aly.fileprovider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/file_paths" />
