Google Drive API - 名称不得为空:null(但我已将有效的帐户名称传递给GoogleAccountCredential)

最近,我有Android代码访问Google云端硬盘.我正在使用Google API Client Library for Java而不是Google Play服务客户端库

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,代码可以在几年内完成100%罚款targetSdkVersion 21.

最近,我将我的应用迁移到targetSdkVersion 23了Google Drive相关代码的0更改.

但是,代码崩溃了FileList fileList = request.execute();,但有以下异常.

使用1.18.0-rc时出现错误日志

如果我谷歌,我得到谷歌驱动器上的Android错误:java.lang.IllegalArgumentException:名称不能为空:null,表明帐户名称不传递给凭证对象.

但是,我非常确定我的凭证对象是以有效的帐户名传递的(格​​式为xxx@gmail.com)

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);

Utils.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正确通过Google Developers Console(适用于调试密钥库和生产密钥库)最近,Android 6引入了运行时权限.我在想,这个例外可以与此相关吗？

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时出现错误日志

更新我的进一步测试

我在使用Nexus 5,Android版本6.0.1进行测试时会生成以上2个错误日志

但是,如果我使用Nexus 4,Android版本5.1.1进行相同的测试,则不会发生错误!1.18.0-rc和1.21.0都运行良好

因此,似乎崩溃与Android版本密切相关.

它看起来像是用于Java的Drive API Client Library调用GoogleAuthUtil.getToken(),这需要GET_ACCOUNTS权限.您需要在清单中具有该权限,并在运行时根据需要请求它.

2> prom85..：

我遇到了同样的问题，所有权限均被授予，但仍然出现此错误。

我简单的问题是，是，googleSignInAccount.getSignInAccount().getAccount()是null。如果您不请求电子邮件权限（GoogleSignInOptions.Builder.requestEmail），就是这种情况。好像没有用户电子邮件就无法创建此帐户。

因此，请确保将此权限添加到GoogleSignInOptions...

就我而言，除请求电子邮件权限外，还需要从“ credential.setSelectedAccountName（）”切换到“ credential.setSelectedAccountName（）”。
