Android上的Google+登錄

Question

我一直在嘗試將Google+登錄功能集成到我的Android應用中，但出現內部錯誤。

我已經在Android開發人員社區上嘗試過該代碼，但現在我收到此錯誤“發生內部錯誤”。

我在這里錯過了什么？

public class MainActivity extends Activity implements ConnectionCallbacks, OnConnectionFailedListener {
    private static final int RC_SIGN_IN = 0;

    private GoogleApiClient mGoogleApiClient;

    private boolean mIntentInProgress;

    private boolean mSignInClicked;
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(Plus.API)
                .addScope(Plus.SCOPE_PLUS_LOGIN)
                .build();
        Button btnLogin = (Button) rootView.findViewById(R.id.btn_signin);
        btnLogin.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (view.getId() == R.id.sign_out_button) {
                    if (mGoogleApiClient.isConnected()) {
                        Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
                        mGoogleApiClient.disconnect();
                        mGoogleApiClient.connect();
                    }
                }

            }
        });
    }
    @Override
    protected void onStart() {
        super.onStart();
        mGoogleApiClient.connect();
    }
    @Override
    protected void onStop() {
        super.onStop();

        if (mGoogleApiClient.isConnected()) {
            mGoogleApiClient.disconnect();
        }
    }
    @Override
    public void onConnectionFailed(ConnectionResult result) {
        if (!mIntentInProgress) {
            if (mSignInClicked && result.hasResolution()) {
                // The user has already clicked 'sign-in' so we attempt to resolve all
                // errors until the user is signed in, or they cancel.
                try {
                    result.startResolutionForResult(this, RC_SIGN_IN);
                    mIntentInProgress = true;
                } catch (SendIntentException e) {
                    // The intent was canceled before it was sent.  Return to the default
                    // state and attempt to connect to get an updated ConnectionResult.
                    mIntentInProgress = false;
                    mGoogleApiClient.connect();
                }
            }
        }
    }
    @Override
    public void onConnected(Bundle connectionHint) {
        mSignInClicked = false;
        Toast.makeText(this, "User is connected!", Toast.LENGTH_LONG).show();
    }

    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        if (requestCode == RC_SIGN_IN) {
            if (responseCode != RESULT_OK) {
                mSignInClicked = false;
            }

            mIntentInProgress = false;

            if (!mGoogleApiClient.isConnected()) {
                mGoogleApiClient.reconnect();
            }
        }
    }
}

對於google plus登錄集成，您無需創建api密鑰。但是您需要使用sha密鑰和包名稱在google api控制台中為您的應用創建一個auth客戶端。您還可以為debug sha和release創建多個auth客戶端沙。 希望這會幫助你。
