如何在Android上使用Apache Tika

Question

我正在尝试使用Apache Tika解析一些文档，但它给了我很多错误和警告。

build.gradle

dependencies {
    ...
    compile ('org.apache.tika:tika-parsers:1.14'){
        exclude group: 'org.json', module: 'json'
        exclude group: 'commons-logging', module: 'commons-logging'
        exclude group: 'org.apache.httpcomponents', module: 'httpclient'}
...
}

为了让这个问题更容易阅读，我不会在这里粘贴警告（它们有600多个），我会忽略它们，但错误是这些：

请问您有解决这个问题的方法吗？或者，您知道一个更好的库可以用来提取文档的元数据吗？
