The app redirects the user to a web page (using a browser) and it does not works because it has not internet connection.

Examples

QKSMS

The following code snippets show the classes and files that are involved in the generation of the previuos issue.

In order to see how this error is generated, we need to review all the flow event. First, we have the layout that is displayed when the “Donate” option is selected from the menu, the following snippet shows the code related to the “Donate any amount” option with id “donate_paypal” selected by the user.

src/main/res/layout/dialog_donate.xml

    <LinearLayout
101.    android:id="@+id/donate_paypal"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="8dp">

        <com.moez.QKSMS.ui.view.QKTextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
110.        android:text="@string/donate_paypal_button"
            app:type="primary" />

        <com.moez.QKSMS.ui.view.QKTextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="@string/donate_paypal_button_summary"
            app:type="secondary" />

    </LinearLayout>

Once the user has selected the current option, the event flow lands in the “DonationManager” class that manages the donation process. First, at line 200 the previous layout snippet get assigned the event that will be triggered when the user clicks on it.

src/main/java/com/moez/QKSMS/common/DonationManager.java

      View view = mContext.getLayoutInflater().inflate(R.layout.dialog_donate, null);
      view.findViewById(R.id.donate_1).setOnClickListener(clickListener);
      view.findViewById(R.id.donate_5).setOnClickListener(clickListener);
      view.findViewById(R.id.donate_10).setOnClickListener(clickListener);
200.  view.findViewById(R.id.donate_paypal).setOnClickListener(clickListener);

Second, at line 190 the method used before is defined for the option selected for the user. It listens to a click event on the layout defined on the previous file and calls “donatePaypal” method.

src/main/java/com/moez/QKSMS/common/DonationManager.java

    public void showDonateDialog() {

        View.OnClickListener clickListener = view -> {
            switch (view.getId()) {
                case R.id.donate_1:
                    onDonateButtonClicked(SKU_DONATE_1);
                    break;
                case R.id.donate_5:
                    onDonateButtonClicked(SKU_DONATE_5);
                    break;
                case R.id.donate_10:
                    onDonateButtonClicked(SKU_DONATE_10);
                    break;
190.            case R.id.donate_paypal:
191.                donatePaypal();
                    break;
            }
        };

Third, at line 217 the “donatePaypal” method creates an implicit intent for the browser to solved it, but in any moment a connection state validation is made, then when the intent is solve the browser displays an error web page.

src/main/java/com/moez/QKSMS/common/DonationManager.java

    public void donatePaypal() {
217.    Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://bit.ly/QKSMSDonation"));
        mContext.startActivity(browserIntent);
    }
