我的webview不适用于重定向到其他页面的网址.它从应用程序打开浏览器,但不加载webview.任何的想法？

webview的代码是:

webView = (WebView) findViewById(R.id.simpleWebView);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);

webView.setWebViewClient(new WebViewClient());

if(getIntent().getStringExtra("url")!=null){
    loadLink(getIntent().getStringExtra("url"));
}else{
    Toast.makeText(WebViewActivity.this, "Please try again later!", 
    Toast.LENGTH_SHORT).show();
    finish();
}

启用 proguard 时出现以下错误。

java.lang.UnsatisfiedLinkError: No implementation found for java.lang.String com.osolutions.otv.utilities.al.b() (tried Java_com_osolutions_otv_utilities_al_b and Java_com_osolutions_otv_utilities_al_b__)

我也使用初始化了 Cpp 类

static {
     System.loadLibrary("baseUrl");
}

如果我禁用 proguard 它工作正常。启用 proguard 时就是这种情况。

我将 Xcode 更新为版本 13.4，将 android studio 更新为 Chipmunk，在此之后，我在尝试为 ios 构建时遇到以下错误。此问题仅发生在 ios 版本中。

以下是我收到的日志。

我的相对布局为:

    <RelativeLayout
        android:id="@+id/iPay_btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:orientation="horizontal">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="· Use iPay"
            android:textColor="#686A86"
            android:textSize="18sp" />


        <Button
            android:layout_width="50dp"
            android:layout_height="35dp"
            android:layout_alignParentRight="true"
            android:background="@drawable/i_pay"
            android:textAllCaps="false"
            android:textColor="#ffffff" />

    </RelativeLayout>

我希望我的相对布局执行onCLickListener但不起作用.我能够执行setonclicklistener但它只适用于textview部分而不适用于图像.

    btniPay.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //for ipay

        }
    });

这仅适用于文本部分,但不适用于图像.知道我可能会缺少什么.

我有一个firebase数据库,结构如下:

rides{
     A{
       //related datas for a
     }
     B{
       //related datas for b
     }}

所以主要问题是我想得到节点A和B的所有值.我可以使用以下方法获取单个节点的值:

   final Firebase ridesDateRef = ref.child("A");

    // Attach an listener to read the data at our posts reference
    ridesDateRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot snapshot) {
            System.out.println(snapshot.getValue());

            availableRidesList = new ArrayList<>();
            System.out.println("There are " + snapshot.getChildrenCount() + " rides");
            for (DataSnapshot postSnapshot: snapshot.getChildren()) {
                AvailableRidesFirebaseObject rides = postSnapshot.getValue(AvailableRidesFirebaseObject.class);


                AvailableRidesFirebaseObject availableRidesFirebaseObject = new AvailableRidesFirebaseObject();
                availableRidesFirebaseObject.setAdded_on(rides.getAdded_on());
                availableRidesFirebaseObject.setCode(rides.getCode());
                availableRidesFirebaseObject.setDate_of_ride(rides.getDate_of_ride());
                availableRidesFirebaseObject.setDropoff_location(rides.getDropoff_location());
                availableRidesFirebaseObject.setDropoff_coordinate(rides.getDropoff_coordinate());
                availableRidesFirebaseObject.setFullname(rides.getFullname());
                availableRidesFirebaseObject.setOffered_by(rides.getOffered_by());
                availableRidesFirebaseObject.setPickup_location(rides.getPickup_location());
                availableRidesFirebaseObject.setPickup_coordinate(rides.getPickup_coordinate());
                availableRidesFirebaseObject.setSeats(rides.getSeats());
                availableRidesFirebaseObject.setShare(rides.getShare());
                availableRidesFirebaseObject.setVechile_type(rides.getVechile_type()); …
