在尝试登录Googleplus时，Android应用程序无一例外地会崩溃

Question

我正在开发一个应用程序，它有一个带有谷歌+登录按钮的LoginActivity。我已经在Google的API控制台中启用了Google+API，并创建了一个Oauth帐户。

这是我代码的相关部分：

活动类声明：

    public class LoginActivity extends Activity implements OnClickListener,
            ConnectionCallbacks, OnConnectionFailedListener, PlusClient.OnAccessRevokedListener {
  private PlusClient mPlusClient;
  private ConnectionResult mConnectionResult;
  private static final int REQUEST_CODE_SIGN_IN = 2

onCreate：

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity").build();

on点击：

     public void onClick(View view) {
        Utils.LOGD("onClick - View = " + view);
        if (view.getId() == R.id.sign_in_button) {
            Utils.LOGD("onClick  : mPlusClient status  = " + mPlusClient);
            if (mPlusClient.isConnected()) {
                Utils.LOGD("onClick - mPlusClient is connected");
                Toast.makeText(this, "you are already signed in!", Toast.LENGTH_LONG).show();
            } else {
                    Utils.LOGD(" mConnectionResult before trying to connect = " + mConnectionResult);
                    if (mConnectionResult == null) {
                        return;
                    }
                try {

                    mConnectionResult.startResolutionForResult(LoginActivity.this, REQUEST_CODE_SIGN_IN);
                } catch (IntentSender.SendIntentException e) {
                    Utils.LOGD( "Exception caught : ) " +  e.getMessage()) ;
                    mPlusClient.connect();
                }
            }

onActivityResult:

       @Override
      public void onActivityResult(int requestCode, int resultCode, Intent data) {
            if (requestCode == REQUEST_CODE_SIGN_IN) {
                  if (resultCode == RESULT_OK && !mPlusClient.isConnected()
                          && !mPlusClient.isConnecting()) {
                        // This time, connect should succeed.
                        mPlusClient.connect();
                        Utils.LOGD("onActivityResult : mConnectionResult AFTER  trying to connect = " + mConnectionResult);
                        Utils.LOGD(" onActivityResult result code   = " + resultCode);
                     
                  }
            }
      }

问题是在我点击登录按钮后，谷歌的内置"；正在加载"进度条显示，应用程序突然退出手机主屏幕，设备本身或日志中没有任何错误显示！

此外，当我在应用程序崩溃后返回时，我看到登录已成功完成，onConnected已被调用，并且我使用我的谷歌帐户登录。（登录后我有一个显示我名字的editText）

这种情况几乎每次我点击按钮时都会发生，但并非总是如此。我还注意到，当在模拟器上运行应用程序时，这种崩溃几乎从未发生过。（尽管这种情况发生过几次）

我还添加了日志，以查看onConnected onStop和onDestroy何时被称为

这是从我点击登录到崩溃后的日志：

调试后，我看到应用程序正好在线路上崩溃mConnectionResult.startResolutionForResult（LoginActivity.this，REQUEST_CODE_SIGN_IN）

怎么了？我该怎么办？

Answer 1

从清单中LoginActivity的<activity>定义中删除android:noHistory="true"。我很确定noHistory设置会导致Android在启动Google+登录活动时完成LoginActivity。既然活动已经完成，就没有任何东西可以调用onActivityResult()了。你的应用程序实际上并没有崩溃，只是完成了。

如果你想确保用户不会返回到你的LoginActivity，你就必须用另一种方式来解决这个问题（覆盖onBackPressed()或其他东西）。

Answer 2

android:noHistory="true"的解决方案是覆盖活动B的onBackPressed方法。

private static final int TIME_INTERVAL = 2000;
private long mBackPressed;
@Override
public void onBackPressed() {
    if (mBackPressed + TIME_INTERVAL > System.currentTimeMillis()) {
        // exiting app
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            finishAffinity();
        }
        else {
            finish();
            System.exit(0);
        }
        return;
    } else {
        showSnackBar(R.string.exit_app);
    }
    mBackPressed = System.currentTimeMillis();
}
