我有一些奇怪的问题:

我在我的布局中添加了MediaRouteButton

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/group_right"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_alignParentRight="true"
    android:orientation="horizontal" >

    <LinearLayout
        android:id="@+id/right_btns"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:minWidth="@dimen/actionbar_icon_width"
        android:orientation="horizontal" >
    </LinearLayout>

    <android.support.v7.app.MediaRouteButton
        android:id="@+id/media_route_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
</LinearLayout>

它在我的新设备上工作得非常好.但对于3.1,3.3或更低版本的旧设备,我遇到了这个例外

我目前正在使用Firebase.目前我正在使用com.google.firebase:firebase-auth:10.0.1

创建用户,登录就像魅力一样.

现在我想为用户添加一个选项,用户可以在其中更改他/她的displayName和profileImage

在Activity AI中,通过单击按钮调用此方法:

   public void updateFirebaseUser(String newDisplayName, Uri newPhotoUri) {
      final FirebaseAuth auth = FirebaseAuth.getInstance();
      final FirebaseUser user = auth.getCurrentUser();
      if (user == null || (TextUtils.isEmpty(newDisplayName) && newPhotoUri == null)) {
         return;
      }
      UserProfileChangeRequest.Builder builder = new UserProfileChangeRequest.Builder();

      if (!TextUtils.isEmpty(newDisplayName)) {
         builder.setDisplayName(newDisplayName);
      }
      if (newPhotoUri != null) {
         builder.setPhotoUri(newPhotoUri);
      }
      UserProfileChangeRequest request = builder.build();
      user.updateProfile(request)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
               @Override
               public void onComplete(@NonNull Task<Void> task) {
                  Toast.makeText(context, "profile update success = " + task.isSuccessful(),
                        Toast.LENGTH_SHORT)
                        .show();
               }
            }); …
