Question

我浏览了整个网络，可能的解决方案是使每个firebase依赖项的版本相同，但这样做会引发同样的错误。

Process: com.bookbud.hp.firebasebook, PID: 5025 java.lang.NoSuchMethodError:

主要活动。为简单起见，省略了import语句和其他不必要的代码。

package com.bookbud.hp.firebasebook;

import android.os.Handler;//others are also included

public class MainActivity extends AppCompatActivity implements 
SearchView.OnQueryTextListener,SwipeRefreshLayout.OnRefreshListener{
   private String n;
   private String c;
   private String a;
   private String cc;
   private String r;
   private String cn;
   private String e;
   private String p;
   private String d;
   private String i;
   private String contact;
   private String email;
   private String ed;
   private String pubi;
   private AdView mAdView;
   private SearchView mSearchView;
   private ListView listView ;
   private ArrayList<book> b;
   private SwipeRefreshLayout swipeRefreshLayout;
   boolean doubleBackToExitPressedOnce = false;
   private ShareActionProvider mShareActionProvider;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.word_list);
       request.isTestDevice(MainActivity.this);

       mAdView = (AdView) findViewById(R.id.adView);
       AdRequest adRequest = new AdRequest.Builder().build();
       mAdView.loadAd(adRequest);
       listView = (ListView) findViewById(R.id.listview_with_fab);
       mSearchView = (SearchView) findViewById(R.id.searchView1);

       b = new ArrayList<book>();
       swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipe_refresh_layout);
       swipeRefreshLayout.setOnRefreshListener(this);
       swipeRefreshLayout.setRefreshing(true);

       DatabaseReference connectedRef = 
       FirebaseDatabase.getInstance().getReference(".info/connected");

依赖关系，都是相同的版本。我不认为我错过任何一个。

compile 'com.google.android.gms:play-services-ads:10.2.1'
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-core:10.2.0'
compile 'com.google.firebase:firebase-ads:10.2.0'
compile 'com.google.firebase:firebase-database:10.2.0'
compile 'com.android.support:design:25.3.1'
compile 'com.google.firebase:firebase-appindexing:10.2.0'
compile 'com.google.firebase:firebase-storage:10.2.0'
compile 'com.google.firebase:firebase-auth:10.2.0'

Answer 1

您的play-services-ads版本为10.2.1，但您的firebase-ads版本为10.2.0。

他们需要是相同的版本。
