没有静态方法 decodeBase64 - Google Credential

Question

我构建了一个带有服务帐户的 Android 应用程序，用于将文件上传到 Google Drive，该应用程序在模拟器和 Android Nougat 上完美运行。现在，我在装有 Android 8.1 的三星 Galaxy Tab A 上进行了尝试，在实施服务帐户之前一切正常。现在，当我尝试从中将文件保存到 google Drive 上时，出现错误：

java.lang.NoSuchMethodError: No static method decodeBase64(Ljava/lang/String;)[B in class Lorg/apache/commons/codec/binary/Base64; or its super classes (declaration of 'org.apache.commons.codec.binary.Base64' appears in /system/framework/org.apache.http.legacy.boot.jar)

有问题的代码是我登录的地方，特别是在fromStream 方法中：

private Credential authorize () throws IOException {
    InputStream in = getAssets().open("credentials.json");
    return GoogleCredential.fromStream(in)
            .createScoped(Collections.singleton(DriveScopes.DRIVE_FILE));
}

这些是实现的新库，我添加了 commons-codec:commons-codec:1.15 因为我读到它可能是由它引起的，但它仍然不起作用：

//API Google Drive
implementation 'com.google.android.gms:play-services-auth:19.0.0'
implementation('com.google.api-client:google-api-client-android:1.26.0') {
    exclude group: 'org.apache.httpcomponents'
    exclude module: 'guava-jdk5'
}
// https://mvnrepository.com/artifact/com.google.apis/google-api-services-drive
implementation('com.google.apis:google-api-services-drive:v3-rev136-1.25.0') {
    exclude group: 'org.apache.httpcomponents'
    exclude module: 'guava-jdk5'
}

implementation 'com.google.http-client:google-http-client-gson:1.26.0'

implementation 'commons-codec:commons-codec:1.15'

我该如何解决？

编辑：这些是我在整个项目中使用的唯一 apaches 库，但它们已用于在本地编写 .xlsx 文件，并且在实施服务之前从未在 Galaxt Tab A 上给我任何问题凭据：

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CellStyle;
import org.apache.poi.ss.usermodel.Font;
import org.apache.poi.ss.usermodel.HorizontalAlignment;
import org.apache.poi.ss.usermodel.IndexedColors;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

这是一个known issue，您使用的是google-api-client-android 的版本。解决方法是将版本从1.26升级到1.28（或者降级到1.25，见this comment）。

我能够使用 Empty Activity 项目和具有 API 级别 26 和目标 Android 8.0 (Google API) 的虚拟设备重现该问题

Build.gradle 内容：

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {

    //changing the version here from 1.26.0 to 1.28.0 resolves the issue
