更新
我的应用程序不断在实时应用程序中崩溃。每周有100-200次崩溃。所以我开始悬赏这个问题。如果有人解决了。请帮忙。
但是,有99%的用户没有崩溃。这些崩溃可能会影响我的应用在Play商店上的存储库。因此,如果我没有解决方案,那么我将最终删除此功能,以在FirebaseAuth中通过电子邮件/密码登录:/
问题:
我在Android应用程序Firebase Auth Login中发生了多次崩溃(来自249个用户的295次崩溃)。尝试通过电子邮件密码登录的1-2%用户遇到此崩溃。我研究了此错误,并得到了提示,当this answer.不能运行播放服务时会发生这种情况
仅供参考,google / facebook身份验证运行正常。此问题仅在通过电子邮件密码登录中。
我尝试了什么?
我试图在登录方法上放置一个try-catch块。并尝试捕获此异常。作为解决方案,我想显示一个对话框,通知用户播放服务未运行。而且他可以手动打开Play商店以启动播放服务,然后再访问此页面。
但是,正如我在Fabric上看到的那样,崩溃永远不会引起阻塞,并且当发生此异常时应用程序崩溃。因为FirebaseAuth SDK中会引发此错误。
需要什么?
首先,我想确定此异常的原因。如果由于播放服务未运行而发生这种情况,那么我想向用户显示一个对话框。当前从不显示,并且在发生以下异常后崩溃。

尝试此代码
bt.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (Validation.loginValidation(edtEmail, edtPass)) {
loginFirebase(edtEmail.getText().toString(), edtPass.getText().toString(), firebaseAuth);
}
}
});
public void loginFirebase(String email, String pass, FirebaseAuth firebaseAuth) {
progressDialog.setTitle("Please Wait.....");
progressDialog.setMessage("Processing....");
progressDialog.setCancelable(false);
progressDialog.show();
(firebaseAuth.signInWithEmailAndPassword(email, pass)).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
progressDialog.dismiss();
Toast.makeText(getActivity(), "Login Successful", Toast.LENGTH_LONG).show();
Intent i = new Intent(getActivity(), DrawerMain.class);
startActivity(i);
edtEmail.setText("");
edtPass.setText("");
} else {
Log.e("Error", task.getException().toString());
Toast.makeText(getActivity(), task.getException().getMessage(), Toast.LENGTH_LONG).show();
}
}
});
}
希望能对您有所帮助!
谢谢。

使用addOnCompleteListener
时,始终需要检查task
是否成功。
尝试以下操作,
somethingTask().addOnCompleteListener(task -> {
if (!task.isSuccessful()) {
Log.wtf(TAG, "somethingTask:ERROR", task.getException());
return;
}
Log.i(TAG, "somethingTask:SUCCESS");
// Now we are logged in, let's write next code!
}
我正在根据您的错误堆栈跟踪来写此答案,该跟踪在getResult
方法中引发了tryLogin
的错误。
+ ,因为addOnCompleteListener
是一种asynchronous
方法,所以您不会捕获这种异常。
