報錯：

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

程式碼：

  <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" />
 

解決：由於多個lib庫中定義類相同所以衝突，整合FileProvider重寫個類即可。

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" />
