Default FirebaseApp is not initialized android studio

问题

当我运行应用程序时，启动应用程序时出现错误。它告诉我忘记在Firebase上做某些事情，并显示以下内容：java.lang.IllegalStateException: 在此进程com.t.androiduberremake中未初始化默认的FirebaseApp。请确保首先调用FirebaseApp.initializeApp(Context)。

以下是您的代码：

  1. private final static int LOGIN_REQUEST_CODE = 7171;
  2. private List<AuthUI.IdpConfig> providers;
  3. private FirebaseAuth firebaseAuth;
  4. private FirebaseAuth.AuthStateListener listener;
  6. @Override
  7. protected void onCreate(Bundle savedInstanceState) {
  8.     super.onCreate(savedInstanceState);
  9.     FirebaseApp.initializeApp(this);
  10.     init();
  11. }
  13. private void init() {
  14.     providers = Arrays.asList(
  15.             new AuthUI.IdpConfig.PhoneBuilder().build(),
  16.             new AuthUI.IdpConfig.GoogleBuilder().build());
  18.     firebaseAuth = FirebaseAuth.getInstance();
  19.     listener = myFirebaseAuth -> {
  20.         FirebaseUser user = myFirebaseAuth.getCurrentUser();
  21.         if (user != null)
  22.             delaySplashScreen();
  23.         else
  24.             showLoginLayout();
  25.     };
  26. }
  28. private void showLoginLayout() {
  29.     AuthMethodPickerLayout authMethodPickerLayout = new AuthMethodPickerLayout
  30.             .Builder(R.layout.layout_sign_in).setPhoneButtonId(R.id.btn_phone_sign_in)
  31.             .setGoogleButtonId(R.id.btn_google_sign_in).build();
  33.     startActivityForResult(AuthUI.getInstance()
  34.             .createSignInIntentBuilder()
  35.             .setAuthMethodPickerLayout(authMethodPickerLayout)
  36.             .setIsSmartLockEnabled(false).setAvailableProviders(providers)
  37.             .build(), LOGIN_REQUEST_CODE);
  38. }
  40. private void delaySplashScreen() {
  41.     Completable.timer(5, TimeUnit.SECONDS, AndroidSchedulers.mainThread())
  42.             .subscribe(() -> Toast.makeText(SplashScreenActivity.this, "Splash Screen done!! ", Toast.LENGTH_SHORT).show());
  43. }
  45. @Override
  46. protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
  47.     super.onActivityResult(requestCode, resultCode, data);
  49.     if (requestCode == LOGIN_REQUEST_CODE) {
  51.         IdpResponse response = IdpResponse.fromResultIntent(data);
  52.         if (resultCode == RESULT_OK) {
  53.             FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
  54.         } else {
  55.             Toast.makeText(this, "[ERROR]: " + response.getError().getMessage(), Toast.LENGTH_SHORT).show();
  56.         }
  57.     }
  58. }

这是当我尝试运行给定的应用程序时控制台向我显示的内容：

  1. java.lang.RuntimeException: 无法启动Activity ComponentInfo{com.t.androiduberremake/com.t.androiduberremake.SplashScreenActivity}：java.lang.IllegalStateException：在此进程com.t.androiduberremake中未初始化默认的FirebaseApp。请确保首先调用FirebaseApp.initializeApp(Context) first。

When I run the app I get an error while launching the app. It shows me that I forgot to do something with FireBase and it shows me this as well: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.t.androiduberremake. Make sure to call FirebaseApp.initializeApp(Context) first.

there&#39;s my code

  1. private final  static int LOGIN_REQUEST_CODE =7171;
  2. private List&lt;AuthUI.IdpConfig&gt; providers;
  3. private FirebaseAuth firebaseAuth;
  4. private FirebaseAuth.AuthStateListener listener;
  5. @Override
  6. protected void onCreate(Bundle savedInstanceState) {
  7. super.onCreate(savedInstanceState);
  8. FirebaseApp.initializeApp(this);
  9. init();
  10. }
  11. private void init() {
  12. providers = Arrays.asList(
  13. new AuthUI.IdpConfig.PhoneBuilder().build(),
  14. new AuthUI.IdpConfig.GoogleBuilder().build());
  15. firebaseAuth  =FirebaseAuth.getInstance();
  16. listener  = myFirebaseAuth -&gt;{
  17. FirebaseUser user = myFirebaseAuth.getCurrentUser();
  18. if(user != null)
  19. delaySplashScreen();
  20. else
  21. showLoginLayout();
  22. };
  23. }
  24. private void showLoginLayout() {
  25. AuthMethodPickerLayout authMethodPickerLayout = new AuthMethodPickerLayout
  26. .Builder(R.layout.layout_sign_in).setPhoneButtonId(R.id.btn_phone_sign_in)
  27. .setGoogleButtonId(R.id.btn_google_sign_in).build() ;
  28. startActivityForResult(AuthUI.getInstance()
  29. .createSignInIntentBuilder()
  30. .setAuthMethodPickerLayout(authMethodPickerLayout)
  31. .setIsSmartLockEnabled(false).setAvailableProviders(providers)
  32. .build(), LOGIN_REQUEST_CODE);
  33. }
  34. private void delaySplashScreen() {
  35. Completable.timer(5, TimeUnit.SECONDS, AndroidSchedulers.mainThread())
  36. .subscribe(() -&gt; Toast.makeText(SplashScreenActivity.this, &quot;Splash Screen done!! &quot;, Toast.LENGTH_SHORT).show());
  37. }
  38. @Override
  39. protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
  40. super.onActivityResult(requestCode, resultCode, data);
  41. if(requestCode == LOGIN_REQUEST_CODE){
  42. IdpResponse response = IdpResponse.fromResultIntent(data);
  43. if(resultCode == RESULT_OK){
  44. FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
  45. }
  46. else {
  47. Toast.makeText(this, &quot;[ERROR]: &quot;+ response.getError().getMessage(), Toast.LENGTH_SHORT).show();
  48. }
  49. }
  50. }

that is what console shows me when I try to run a given app:

  1. java.lang.RuntimeException: Unable to start activity ComponentInfo{com.t.androiduberremake/com.t.androiduberremake.SplashScreenActivity}: java.lang.IllegalStateException: Default FirebaseApp is not initialized in this process com.t.androiduberremake.

答案1

得分: 1

你还没有将google-services插件添加到你的build.gradle中。这很重要。
根据文档，你还需要添加：

  1. apply plugin: 'com.google.gms.google-services'
英文:

You haven't added the google-services plugin to your build.gradle. Its important.
According to the documentation, you also have to add:

  1. apply plugin: &#39;com.google.gms.google-services&#39;
