package com.demo.office;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

Hello,

你好，感谢您分享更多信息。
针对较高版本，我们产品目前兼容得不是很好。建议你使用较低版本，例如：Gradle：4.4，Gradle plugins：3.1 ，sdk build tools：27。
今后产品针对较高版本兼容性有优化时，我们会及时告知您。

Is it planned to also make the free version kompatible?

[Lisa.Li]

Hello fabian,

Thanks for your message.
Sorry that we only upgrade our free version irregularly. I suggest that you download our latest commercial version Spire.PDF for Android via Java Version:9.5.1 to do your tests, since the latest version contains more features and bug fixes. We are willing to provide a temporary license(one month free) to help you remove the warning message and evaluate our commercial version better. If you need it, just feel free to contact us.

Sincerely,
Lisa
