我正在使用firebase存储来上载文件,但是当我上载时,我得到了这个错误
E/StorageUtil: error getting token java.util.concurrent.ExecutionException: com.google.android.gms.internal.zzand: Please sign in before trying to get a token.
我用谷歌搜索了一下,但找不到答案!
我已经在firebase登录了。
最佳答案
我想你在上传文件之前没有签名。在启动程序活动的oncreate()中,尝试以下代码
FirebaseAuth mAuth = FirebaseAuth.getInstance();
然后在onstart()中,
FirebaseUser user = mAuth.getCurrentUser();
if (user != null) {
// do your stuff
} else {
signInAnonymously();
}
显著地()
private void signInAnonymously() {
mAuth.signInAnonymously().addOnSuccessListener(this, new OnSuccessListener<AuthResult>() {
@Override
public void onSuccess(AuthResult authResult) {
// do your stuff
}
})
.addOnFailureListener(this, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
Log.e(TAG, "signInAnonymously:FAILURE", exception);
}
});
}
这可以解决你的问题
