java - Android强制关闭: could not find newChooseAccountIntent

Question

我在开发 Android 应用程序时遇到了一些问题。我创建了一个应用引擎连接的 Android 应用程序。后端已部署，我正在向端点添加身份验证。代码编译没有错误并在我的设备上启动，但是当我按下按钮进入注册 Activity 时它强制关闭。我检查了 Logcat，它说:

could not find method com.Google.api.client.googleapis.extensions.android.GMs.auth.GoogleAccountCredential.newChooseAccountIntent, referenced by RegistrationActivity.chooseAccount

我该怎么做才能解决这个问题？

Answer 1

所有这些行都必须在 onCreate 方法中:

提示:已经有人告诉您将按钮放在哪里。请参阅代码中的 //Place button here。

protected void onCreate(Bundle savedInstanceState) {

    ...

    //text fields and button stuff [FROM HERE]
    EditText fn = (EditText) findViewById(R.id.firstName); 
    EditText ln = (EditText) findViewById(R.id.lastName);
    EditText org = (EditText) findViewById(R.id.editText1);
    EditText email = (EditText) findViewById(R.id.editText2);
    Button regBut = (Button) findViewById(R.id.regButton);

对于下面几行，你可以像这样保留声明:

private String firstName;
private String lastName;
private String organization;
private String emailAddress;

然后再次在 onCreate 中，将 View 转换到 EditText 之后，您可以像这样读取它们的值:

firstName = fn.getText().toString();
lastName = ln.getText().toString();
organization = org.getText().toString();
emailAddress = email.getText().toString();
