android - GoogleApiClient 连接失败，ConnectionResult 状态码为 SIGN_IN_REQUIRED

Question

[编辑] - 赏金

我正在尝试将我的 Android 应用程序与 Google Drive 连接以同步 MP3 音频文件。需要使用 GoogleDriveAndroidApi 和 GoogleApiClient 连接 Google Drive 的工作代码/示例(除了下面给出的链接)。

这个问题已经被问过很多次了，但是没有一个解决这个问题。所以，我再次提出这个问题。

我是第一次使用 Google Drive Android API，无法通过“为‘APP NAME’选择帐户”屏幕。这是我现在所做的:

1. 尝试访问以下网址:

https://developers.google.com/drive/android/get-started

https://github.com/googledrive/android-quickstart

https://www.numetriclabz.com/integrate-google-drive-in-android-tutorial/

1. 在我的 build.gradle 中使用 compile 'com.google.android.gms:play-services-drive:10.0.1'(如果有任何不同)

2. 到目前为止尝试的代码:

    public class ARCBackupActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks,
               GoogleApiClient.OnConnectionFailedListener {
   
           private static final int REQUEST_CODE = 1;
   
           private GoogleApiClient mGoogleApiClient;
           private Toolbar mToolbar;
   
           @Override
           protected void onCreate(Bundle savedInstanceState) {
               super.onCreate(savedInstanceState);
               setContentView(R.layout.arc_activity_backup);
   
               mToolbar = (Toolbar) findViewById(R.id.toolbar);
               setSupportActionBar(mToolbar);
   
               getSupportActionBar().setDisplayShowTitleEnabled(false);
               getSupportActionBar().setDefaultDisplayHomeAsUpEnabled(true);
               getSupportActionBar().setDisplayHomeAsUpEnabled(true);
   
           }
   
   
           @Override
           protected void onResume() {
               super.onResume();
               if (mGoogleApiClient == null) {
                   // Create the API client and bind it to an instance variable.
                   // We use this instance as the callback for connection and connection
                   // failures.
                   // Since no account name is passed, the user is prompted to choose.
                   mGoogleApiClient = new GoogleApiClient.Builder(this)
                           .addApi(Drive.API)
                           .addScope(Drive.SCOPE_FILE)
                           .addConnectionCallbacks(this)
                           .addOnConnectionFailedListener(this)
                           .build();
               }
               // Connect the client. 
               mGoogleApiClient.connect();
           }
   
           @Override
           protected void onPause() {
               if (mGoogleApiClient != null) {
                   mGoogleApiClient.disconnect();
               }
               super.onPause();
           }
   
           @Override
           protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {
               switch (requestCode) {
   
                   case REQUEST_CODE:
   
                       if (resultCode == Activity.RESULT_OK) {
                           mGoogleApiClient.connect();
                       }
                       break;
               }
           }
   
           @Override
           public void onConnectionFailed(ConnectionResult result) {
               // Called whenever the API client fails to connect.
               Log.i(Const.DEBUG, "GoogleApiClient connection failed: " + result.toString());
               if (!result.hasResolution()) {
                   // show the localized error dialog.
                   GoogleApiAvailability.getInstance().getErrorDialog(this, result.getErrorCode(), 0).show();
                   return;
               }
               // The failure has a resolution. Resolve it.
               // Called typically when the app is not yet authorized, and an
               // authorization
               // dialog is displayed to the user.
               try {
                   result.startResolutionForResult(this, REQUEST_CODE);
               } catch (IntentSender.SendIntentException e) {
                   Log.e(Const.DEBUG, "Exception while starting resolution activity", e);
               }
           }
   
           @Override
           public void onConnected(Bundle connectionHint) {
               Log.d(Const.DEBUG, "API client connected.");
   
               //saveFileToDrive();
           }
   
           @Override
           public void onConnectionSuspended(int cause) {
               Log.d(Const.DEBUG, "GoogleApiClient connection suspended");
           }
       }
   

   我在这里缺少什么？非常感谢任何具有良好解释的完整示例。

   如果我在构建 googleApiClient 时添加 Plus.API，它会解决卡在选择帐户循环中的问题。但是，Plus.API 已被弃用，是否有仅通过使用 GoogleApiClient 的解决方法？

   这里是修改后的代码:

    @Override
       protected void onResume() {
           super.onResume();
   
           if (mGoogleApiClient != null && mGoogleApiClient.isConnected()) {
               Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
               mGoogleApiClient.disconnect();
           }
   
   
           if (mGoogleApiClient == null) {
               // Create the API client and bind it to an instance variable.
               // We use this instance as the callback for connection and connection
               // failures.
               // Since no account name is passed, the user is prompted to choose.
               mGoogleApiClient = new GoogleApiClient.Builder(this)
                       .addApi(Drive.API)
                       .addApi(Plus.API)
                       .addScope(Drive.SCOPE_FILE)
                       .addConnectionCallbacks(this)
                       .addOnConnectionFailedListener(this)
                       .build();
           }
           // Connect the client.
           mGoogleApiClient.connect();
       }
   

仍在寻找正确的实现方式...

看来你的问题是因为

@Override
protected void onPause() {
    if (mGoogleApiClient != null) {
        mGoogleApiClient.disconnect();
    }
    super.onPause();
}

让我解释一下。当帐户选择器出现时，它使您的 Activity 调用 onPause()。在 onPause() 中调用 mGoogleApiClient.disconnect()。

因此，在选择帐户后(调用 onResume 和 onActivityResult 时)您将拥有新的 GoogleApiClient。

要解决此问题，只需将 mGoogleApiClient.connect() 和 mGoogleApiClient.disconnect() 放在您 Activity 的 onStart()/onStop() 方法中或使用 enableAutoManage(Activity, OnConnectionFailedListener) 为您的 GoogleApiClient。

编码愉快! :)
