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）

标签： android google-drive-api

最近，我有Android代码访问Google云端硬盘。我使用 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targetSdkVersion 21，则代码可以正常工作几年。

最近，我将我的应用迁移到targetSdkVersion 23，对Google云端硬盘相关代码进行了0次更改。

然而，代码在FileList fileList = request.execute();崩溃了，但有以下例外。

使用1.18.0-rc时的错误日志

如果我谷歌，我会得到Google Drive on android error: java.lang.IllegalArgumentException: the name must not be empty: null，其中说明帐户名称未传递给凭据对象。

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，我非常确定通过Google Developers Console正确使用我的OAuth 2.0（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时的错误日志

我的进一步测试更新

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都正常工作

因此，似乎崩溃与Android版本密切相关。

5 个答案:

答案 0 :(得分：13)

看起来，用于Java的Drive API客户端库调用GoogleAuthUtil.getToken()，这需要GET_ACCOUNTS权限。您需要在清单中拥有该权限，并在运行时根据需要请求它。

答案 1 :(得分：4)

我遇到了同样的问题，所有权限都被授予了，但我仍然遇到了这个错误。

我的简单问题是googleSignInAccount.getSignInAccount().getAccount()是null。如果您不请求电子邮件权限（GoogleSignInOptions.Builder.requestEmail），则会出现这种情况。似乎此帐户无法在没有用户电子邮件的情况下创建。

因此，请务必将此权限添加到GoogleSignInOptions ...

答案 2 :(得分：2)

这是因为从stdout开始，您需要在调用Google端点之前获取“联系”权限。

您可以在此处查看完整的详细信息 - https://developer.android.com/training/permissions/requesting.html

仅适用于危险权限和权限组（基于它们与用户隐私的关联程度）。更多详情 - https://developer.android.com/guide/topics/security/permissions.html#perm-groups

答案 3 :(得分：1)

就我而言（Google Drive REST API v3），ProGuard是罪魁祸首，因为代码在调试模式下运行良好。

只需在ProGuard规则中添加d = { key: value } | d 即可解决问题。

PS：我必须打-keep class com.google.** { *;}，但我没有要求任何requestEmail()许可。

答案 4 :(得分：1)

我使用google api客户端

remote
// Dependency of Google Api client
implementation 'com.google.api-client:google-api-client:1.30.9'
implementation 'com.google.api-client:google-api-client-android:1.30.9'
implementation 'com.google.apis:google-api-services-drive:v3-rev20200413-1.30.9'

您可以从GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) .requestScopes(new Scope(Scopes.DRIVE_APPFOLDER)) //requestEmail required .requestEmail() .build(); GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(this, gso); // in onActivityResult method Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data); GoogleSignInAccount account = completedTask.getResult(ApiException.class); // androidAccount will be null if no email android.accounts.Account androidAccount = account.getAccount(); 的源代码中看到它

android.accounts.Account
