onActivityResult: 传递结果失败 ResultInfo
onActivityResult: Failure delivering result ResultInfo
我正在尝试设置 google 登录我的登录 activity 但我在 onActivityResult
上收到此错误
java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=9001, result=-1, data=Intent { (has extras) }}
我检查并尝试了许多针对此错误的解决方案,这些解决方案已发布在其他问题上,但根本没有帮助!
这里是我如何在 activity class
中使用它
private lateinit var googleSignInClient: GoogleSignInClient
val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(GOOGLE_CLIENT_ID)
.requestEmail()
.build()
googleSignInClient = GoogleSignIn.getClient(this, gso)
startActivityForResult(googleSignInClient.signInIntent!!, RC_SIGN_IN)
这是 activity 结果
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode!=RESULT_CANCELED){
if (requestCode == RC_SIGN_IN && data!=null) {
Log.d(TAG, "onActivityResult $mPresenter : $requestCode : $resultCode : $data")
mPresenter!!.result(requestCode, resultCode, data) // line of the error 73
}
}
}
这里是错误的完整 logcat

此处日志中onActivityResult中的数据根本不为空
LoginActivity: onActivityResult c.d.a.a.a.e@97eb6e3 : 9001 : -1 : Intent { (has extras) }
这里是 Presenter 中的 result 方法和 Interactor 中的附加方法 class
// in presenter class
override fun result(requestCode: Int, resultCode: Int, data: Intent?) {
mInteractor!!.performResult(requestCode, resultCode,data)
}
// in interactor class
override fun performResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == RC_SIGN_IN) {
val task = GoogleSignIn.getSignedInAccountFromIntent(data)
try {
// Google Sign In was successful, authenticate with Firebase
val account = task.getResult(ApiException::class.java)!!
mListener!!.onStart(account.idToken!!)
} catch (e: ApiException) {
// Google Sign In failed, update UI appropriately
mListener!!.onFailure(e)
// Log.w(TAG, "Google sign in failed", e)
}
}
}
一般来说,您不应在代码中使用 !!
。选择双感叹号是为了向你尖叫,就像在 don't use it!!
中一样。当您使用 !!
时,您基本上禁用了 Kotlin 最好的功能之一 - 空安全。
但在你的情况下,这不是问题的根源。
正如我们在日志中看到的,您有一个 mPresenter 实例被引用为 c.d.a.a.a.e@97eb6e3
然后在崩溃日志中我们看到
Caused by: java.lang.NullPointerException
at c.d.a.a.a.d.a(:66)
at c.d.a.a.a.e.f(:34)
at com.googlemvp.signin.ui.LoginActivity.onActivityResult(:73)
注意通话记录是从下到上的,从你的activity第73行我们进入mPresenter
第34行,然后到其他classc.d.a.a.a.d.a
第 66 行实际发生 NullPointerException
的地方。
您应该遵循此日志并修复第三个 class.
