我在对话框片段中使用了firebase数据库。当下面的代码已运行FirebaseDatabase.getInstance（）崩溃
private FirebaseDatabase firebaseDatabase=FirebaseDatabase.getInstance();
我找遍了所有的解决方案，如的gradle变化的依赖性和下载谷歌，service.json文件
等它越来越崩溃，但问题仍未解决。我附上我的代码的所有细节，请给出正确的解决方案。由于
public class FireViewFragment extends DialogFragment {
TextView name, email, username;
Button ok;
MyDialogInterface myDialogInterface;
private FirebaseDatabase firebaseDatabase = FirebaseDatabase.getInstance();
public FireViewFragment(MyDialogInterface myDialogInterface) {
this.myDialogInterface = myDialogInterface;
Log.d("Interface", "Constractor");
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_fire_view, container, false);
name = (TextView) view.findViewById(R.id.dis_name);
email = (TextView) view.findViewById(R.id.dis_email);
username = (TextView) view.findViewById(R.id.dis_uname);
ok = (Button) view.findViewById(R.id.ok);
ok.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
myDialogInterface.setMyDialogInterface("hi", false);
}
});
return view;
}}
的build.gradle（Module.app）
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile('com.crashlytics.sdk.android:crashlytics:[email protected]') {

我猜猜它与不同版本的Firebase和地图有关。尝试使用'compile'com.google.android.gms：play-services-maps：9.2.0'，与firebase相同的版本是... – Opiatefuchs
@Opiatefuchs您给出了很好的解决方案。没有这个，我已经改变了gradle依赖关系中的所有更改。 Yhaaa。，它的工作谢谢 –
很高兴帮助... – Opiatefuchs
