我正在尝试将facebook与我在android studio中的应用程序集成。我是Kotlin语言的业余爱好者，可以用来实现自己的目标。
我遵循了Facebook开发者页面上的教程。问题是，一旦我按下登录按钮，它就会加载2到3秒钟，然后崩溃/关闭。
LoginActivity.kt file
val fblogin_button= findViewById<LoginButton>(R.id.login_button)
fblogin_button.setOnClickListener {
callbackManager = CallbackManager.Factory.create()
LoginManager.getInstance().logInWithReadPermissions(this,Arrays.asList("email"))
LoginManager.getInstance().registerCallback(callbackManager,
object : FacebookCallback<LoginResult>{
override fun onSuccess(result: LoginResult) {
Log.d("LoginActivity","Facebook token" + result.accessToken.token)
startActivity(Intent(baseContext,GradeActivity::class.java))
}
override fun onCancel() {
Log.d("LoginActivity","Facebook oncancel")
}
override fun onError(error: FacebookException?) {
Log.d("LoginActivity","Facebook onError")
}
})
}
在onCreate方法之外，我还有另一种方法。如下所示。
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
callbackManager?.onActivityResult(requestCode,resultCode,data)
}
Manifest文件的内容如下所示。

您可以看到onSuccess方法，如果登录成功，则GradeActivity应该打开，而关闭。
日志如下所示。
