请帮帮我...

Answer 1

你必须使用安卓版本的iTextPDF。

下载 "itextg-5.4.3.jar"

Answer 2

对于意外的顶级异常：

应用分级：

defaultConfig {
              multiDexEnabled true
              }

外部标签：

afterEvaluate {
    tasks.matching {
        it.name.startsWith('dex')
    }.each { dx ->
        if (dx.additionalParameters == null) {
            dx.additionalParameters = ['--multi-dex']
        } else {
            dx.additionalParameters += '--multi-dex'
        }
    }
}

如果仍然错误，则可以增加堆大小。

 android.dexOptions {
        javaMaxHeapSize "4g"
        preDexLibraries false
    }
