Google Drive API - the name must not be empty: null (But I had passed valid account name to GoogleAccountCredential)

Question

Recently, I have Android code which accesses to Google Drive. I'm using Google APIs Client Library for Java instead of 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();

The code works 100% fine for several years, if I use targetSdkVersion 21.

Recently, I migrate my app to targetSdkVersion 23, with 0 change on Google Drive related code.

However, the code crashes mystery at FileList fileList = request.execute();, with the following exception.

Error log while using 1.18.0-rc

If I google, I get Google Drive on android error: java.lang.IllegalArgumentException: the name must not be empty: null , which states that account name is not passed to credential object.

However, I'm pretty much sure that my credential object is passed with valid account name (in format [email protected])

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();
}

Also, I'm pretty sure that my OAuth 2.0 correctly through Google Developers Console (For both debug keystore & production keystore) Recently, Android 6 introduces run-time permissions. I was wondering, can this exception related to that?

I further try with latest library version 1.21.0. However, I still get similar error log

Update on my further testing

The above 2 error logs are generated while I'm testing using Nexus 5, Android version 6.0.1

However, if I conduct the same testing using Nexus 4, Android version 5.1.1, no error occurs! Both 1.18.0-rc and 1.21.0 are working fine

Hence, it seems the crash is strongly related to Android version.

Answer 1

It looks like the Drive API Client Library for Java calls into GoogleAuthUtil.getToken(), which requires the GET_ACCOUNTS permission. You need to have that permission in your manifest and request it at runtime, as appropriate.

UPDATE: With Google Drive REST v3 API, GET_ACCOUNTS permission is not required. Instead, Email permission is required. You can ask for it by calling GoogleSignInOptions.Builder.requestEmail.

Answer 2

I had the same problem, all permissions were granted and still I got this error.

My simple problem was, that the googleSignInAccount.getSignInAccount().getAccount() was null. This is the case, if you do NOT request the email permissions (GoogleSignInOptions.Builder.requestEmail). Seems like this account can't be created without the user email.

So make sure to add this permission to the GoogleSignInOptions...
