为什么我总是得到“java.lang.IllegalStateException:DriveContents已经关闭。”

我正在制作一个最小的可行示例,以演示How to avoid from always loading cached app data from Google Drive中描述的错误

我已在https://github.com/yccheok/google-drive-bug

完成了代码

该代码旨在更新现有文本文件或写入新文本文件。

然而,在测试时,我总是在driveContents.commit

中获得异常
Status status;
try {
    status = driveContents.commit(googleApiClient, null).await();
} catch (java.lang.IllegalStateException e) {
    // java.lang.IllegalStateException: DriveContents already closed.
    Log.e(TAG, "", e);
    return false;
}

例外的细节如下。

java.lang.IllegalStateException: DriveContents already closed.

      at com.google.android.gms.drive.internal.zzv.commit(Unknown Source)

      at java.lang.Thread.run(Thread.java:818)

我已经调试了很长时间,但仍然不知道为什么。我认为我没有错过任何步骤。

设置正确的API密钥

    不确定我错过了哪些步骤,导致此行始终抛出异常 - https://github.com/yccheok/google-drive-bug/blob/master/app/src/main/java/org/yccheok/demo/Utils.java#L233

答案 0 :(得分:0)

根据https://developers.google.com/android/reference/com/google/android/gms/drive/DriveContents

  

提交此DriveContents实例后,用于   创建或丢弃,它变得封闭和任何后续方法   call将抛出IllegalStateException。

我不应在driveContents.commit之后致电driveFolder.createFile

我通过https://github.com/yccheok/google-drive-bug/commit/70919dcfe3fd9108c3af9ecf939a6c0ef03e07cc
