无法将对象转换为JSON

问题描述

早上好，当我尝试通过虚拟设备进行注册或登录时出现此错误:

Good morning, I have this error when I try to register or login via my virtual device :

E/StorageHelpers: Failed to turn object into JSON   java.lang.NullPointerException: Attempt to invoke virtual method   'org.json.JSONObject com.google.firebase.auth.internal.zzm.zzbf()' on a null  object reference at com.google.firebase.auth.internal.zzz.zzi(Unknown Source) at  com.google.firebase.auth.internal.zzz.zzg(Unknown Source) at com.google.firebase.auth.FirebaseAuth.zza(Unknown Source) at com.google.firebase.auth.FirebaseAuth$zza.zza(Unknown Source) at com.google.firebase.auth.api.internal.zzbq.zzaa(Unknown Source) at com.google.firebase.auth.api.internal.zzcy.zzal(Unknown Source) at  com.google.firebase.auth.api.internal.zzcy.zza(Unknown Source) at com.google.firebase.auth.api.internal.zzdb.zza(Unknown Source) at com.google.firebase.auth.api.internal.zzci.dispatchTransaction(Unknown Source) at com.google.android.gms.internal.firebase_auth.zzb.onTransact(Unknown Source) at android.os.Binder.execTransact(Binder.java:453)

虚拟设备是Xperia Z3 Android 6.0.1 API23

The virtual device is an Xperia Z3 Android 6.0.1 API23

这是LoginActivity.java的代码:

And this is the code of the LoginActivity.java :

 mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
    @Override
    public void onComplete(@NonNull Task<AuthResult> task) {
        progressBar.setVisibility(View.GONE);
        if (task.isSuccessful()) {
            finish();
            Intent intent = new Intent(LoginActivity.this, menuPrincipal.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            startActivity(intent);
        } else {
            Toast.makeText(getApplicationContext(), task.getException().getMessage(), Toast.LENGTH_SHORT).show();
        }
    }
});

我认为错误来自此行:

因为.getMessageget关于java.lang.NullPointerException的警告，如错误消息中一样.

Because the .getMessageget a warning about a java.lang.NullPointerException, like in the error message.

我在profileImageUrl = taskSnapshot.getDownloadUrl().toString();处的profileRegistration.java中具有相同的警告:

I have the same warning in the profileRegistration.java at profileImageUrl = taskSnapshot.getDownloadUrl().toString(); :

private void uploadImageToFirebaseStorage(){
    StorageReference profilImageRef =    FirebaseStorage.getInstance().getReference("profilepics/" +   System.currentTimeMillis() + ".jpg");

    if (uriProfileImage != null) {
        progressBarImage.setVisibility(View.VISIBLE);
        profilImageRef.putFile(uriProfileImage)
                .addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                    @Override
                    public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                        progressBarImage.setVisibility(View.GONE);
                        profileImageUrl = taskSnapshot.getDownloadUrl().toString();
                    }
                })

您知道是什么原因或如何解决该问题吗?

Any idea what's causing it or how to fix it?

推荐答案

我能够通过将firebase-auth降级为15.0.0来解决此问题

I was able to fix the problem by downgrading firebase-auth to 15.0.0

implementation 'com.google.firebase:firebase-auth:15.0.0'
