android - Google Drive API - 名称不能为空 : null (But I had passed valid account name to GoogleAccountCredential)

Question

最近，我有访问 Google Drive 的 Android 代码。我使用的是 Google APIs Client Library for Java 而不是 Google Play services client library

private static GoogleCloudFile searchFromGoogleDrive(Drive drive, String qString, HandleUserRecoverableAuthIOExceptionable h, PublishProgressable p) {
    try {
        Files.List request = drive.files().list().setQ(qString);

        do {        
            if (p.isCancelled()) {
                return null;
            }

            FileList fileList = request.execute();

如果我使用 targetSdkVersion 21，该代码可以 100% 正常工作数年。

最近，我将我的应用程序迁移到 targetSdkVersion 23，Google Drive 相关代码的更改为 0。

但是，代码在 FileList fileList = request.execute(); 处神秘崩溃，但出现以下异常。

使用 1.18.0-rc 时的错误日志

如果我用谷歌搜索，我会得到 Google Drive on android error: java.lang.IllegalArgumentException: the name must not be empty: null ，它指出帐户名称未传递给凭据对象。

但是，我非常确定我的凭据对象是通过有效的帐户名(格式为 xxx@gmail.com)传递的

protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
    switch (requestCode) {
    case RequestCode.REQUEST_ACCOUNT_PICKER_LOAD_FROM_CLOUD:
        if (resultCode == RESULT_OK && data != null && data.getExtras() != null) {
            String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
            Log.i("CHEOK", "accountName = " + accountName);
            if (accountName != null) {
                JStockApplication.instance().getJStockOptions().setUsername(accountName);
                Utils.getGoogleAccountCredential().setSelectedAccountName(accountName);

实用程序.java

public static GoogleAccountCredential getGoogleAccountCredential() {
    return googleAccountCredential;
}

private static final GoogleAccountCredential googleAccountCredential = GoogleAccountCredential.usingOAuth2(JStockApplication.instance(), 
    Arrays.asList(
        DriveScopes.DRIVE_APPDATA,
        // Legacy. Shall be removed after a while...
        DriveScopes.DRIVE
    )
);

private Drive getDriveService() {
    return new Drive.Builder(AndroidHttp.newCompatibleTransport(), new GsonFactory(), Utils.getGoogleAccountCredential()).build();
}

此外，我非常确定我的 OAuth 2.0 可以通过 Google Developers Console 正确使用(对于调试 keystore 和生产 keystore )最近，Android 6 引入了运行时权限。我在想，这个异常是否与此有关？

我进一步尝试使用最新的库版本 1.21.0。但是，我仍然得到类似的错误日志

使用 1.21.0 时的错误日志

我进一步测试的更新

以上 2 个错误日志是在我使用 Nexus 5，Android 版本 6.0.1 进行测试时生成的

但是，如果我使用 Nexus 4、Android 版本 5.1.1 进行相同的测试，则不会出现错误! 1.18.0-rc 和 1.21.0 都工作正常

因此，崩溃似乎与 Android 版本密切相关。

看起来 Drive API Client Library for Java 调用了 GoogleAuthUtil.getToken()，这需要 GET_ACCOUNTS 权限。您需要在您的 list 中拥有该权限并在运行时根据需要请求它。

更新:使用 Google Drive REST v3 API，不需要 GET_ACCOUNTS 权限。相反，需要电子邮件许可。您可以通过调用 GoogleSignInOptions.Builder.requestEmail 请求它。
