Question

我正在尝试将Google云端硬盘集成到我的应用程序中，但收效甚微。使用快速启动存储库中的代码，每次选择登录用户帐户时都会收到以下错误消息：

I/DriveDemo: GoogleApiClient connection failed: ConnectionResult{statusCode=SIGN_IN_REQUIRED, resolution=PendingIntent{867e070: android.os.BinderProxy@13cdfe9}, message=null}

我按照以下网址的说明进行操作：

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

并按照视频点击：

我还看了很多Stack Overflow问题和答案，不知道我做错了什么。

的manifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.lightkeeper54.chuck.drivedemo">

    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

代码：

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. Once connected, the camera is launched.
    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_CAPTURE_IMAGE:
            // Called after a photo has been taken.
            if (resultCode == Activity.RESULT_OK) {
                // Store the image data as a bitmap for writing later.
                mBitmapToSave = (Bitmap) data.getExtras().get("data");
            }
            break;
        case REQUEST_CODE_CREATOR:

                mBitmapToSave = null;
                // Just start the camera again for another photo.
                startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE),
                        REQUEST_CODE_CAPTURE_IMAGE);
            }
            break;
    }
}

@Override
public void onConnectionFailed(ConnectionResult result) {
    // Called whenever the API client fails to connect.
    Log.i(TAG, "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_RESOLUTION);
    } catch (IntentSender.SendIntentException e) {
        Log.e(TAG, "Exception while starting resolution activity", e);
    }
}

@Override
public void onConnected(Bundle connectionHint) {
    Log.i(TAG, "API client connected.");
    if (mBitmapToSave == null) {
        // This activity has no UI of its own. Just start the camera.
        startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE),
                REQUEST_CODE_CAPTURE_IMAGE);
        return;
    }
    saveFileToDrive();
}

@Override
public void onConnectionSuspended(int cause) {
    Log.i(TAG, "GoogleApiClient connection suspended");
}

Answer 1

根据文档 - SIGN_IN_REQUIRED

客户端尝试连接到该服务但用户未登录。客户端可以选择继续而不使用API。或者，如果hasResolution()返回true，则客户可以致电startResolutionForResult(Activity, int)以提示用户登录。在登录活动返回RESULT_OK后，进一步的尝试应该会成功。

您也可以查看@ Cheok的问题，SO post建议按要求正确添加SHA-1和包名称，并在项目凭据全部设置后启用API。

希望这些信息有所帮助。

Answer 2

我遇到了类似的问题，我确保每个APK版本都是由我在执行时使用的同一个密钥库签署的，并且＃34;获取Android证书并注册您的应用程序＆＃34;正如所描述的here

使用Studio时，我执行了＃34;自动签名＆＃34;按照＆＃34;配置构建过程以自动签署APK＆＃34;中所述的步骤正如here所述。显然，使用与注册应用程序时使用的密钥库相同的密钥库（上图）。

GoogleApiClient连接失败：ConnectionResult {statusCode = SIGN_IN_REQUIRED，
