我是android开发的新手。尝试将fb和Google +登录集成到Android网络视图中。 FB登录正常。但是Google登录名不允许登录。我提到的链接很少，但无法成功。
问题是在gmail中提供了用户名和密码后，我的网站未登录

Google不允许使用WebView的默认实现。因此，您需要为WebView设置自定义User-Agent：
webView.getSettings().setUserAgentString("YourAppName");
您可以使用任何字符串代替YourAppName。

最新答案，但将来可能会有所帮助。
实际上，Google会阻止通过嵌入式浏览器发出的OAuth请求。因此您可以在代码中编写类似的内容：
public static final String USER_AGENT = "Mozilla/5.0 (Linux; Android 4.1.1; Galaxy Nexus Build/JRO03C) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19";
mWebView.getSettings().setUserAgentString(USER_AGENT);
，您应该可以使用google登录。

您必须创建一个自定义的webchromeclient并处理来自webview的弹出窗口。每当需要从网站弹出窗口时，都必须将其加载到警报对话框中。
public class WebViewActivity extends AppCompatActivity {
private WebView webViewPopUp;
private AlertDialog builder;
private Context globalContext;
private String url = "https://www.bellyfulstore.com/";
private WebView webView;
private String userAgent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
webView = findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(url);
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Set User Agent
userAgent = System.getProperty("http.agent");
webSettings.setUserAgentString(userAgent + "yourAppName");
// Enable Cookies
CookieManager.getInstance().setAcceptCookie(true);
if(android.os.Build.VERSION.SDK_INT >= 21)
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
// Handle Popups
webView.setWebChromeClient(new CustomChromeClient());
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setSupportMultipleWindows(true);
globalContext = this.getApplicationContext();
// WebView Tweaks
webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
webSettings.setAppCacheEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webSettings.setSaveFormData(true);
webSettings.setEnableSmoothTransition(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
findViewById(R.id.progressBar).setVisibility(View.VISIBLE);
}
public void onPageFinished(WebView view, String url) {
// do your stuff here
findViewById(R.id.progressBar).setVisibility(View.GONE);
}
});
}
class CustomChromeClient extends WebChromeClient {
@Override
public boolean onCreateWindow(WebView view, boolean isDialog,
boolean isUserGesture, Message resultMsg) {
webViewPopUp = new WebView(globalContext);
webViewPopUp.setVerticalScrollBarEnabled(false);
webViewPopUp.setHorizontalScrollBarEnabled(false);
webViewPopUp.setWebChromeClient(new CustomChromeClient());
webViewPopUp.getSettings().setJavaScriptEnabled(true);
webViewPopUp.getSettings().setSaveFormData(true);
webViewPopUp.getSettings().setEnableSmoothTransition(true);
webViewPopUp.getSettings().setUserAgentString(userAgent + "yourAppName");
// pop the webview with alert dialog
builder = new AlertDialog.Builder(WebViewActivity.this).create();
builder.setTitle("");
builder.setView(webViewPopUp);
builder.setButton("Close", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int id) {
webViewPopUp.destroy();
dialog.dismiss();
}
});
builder.show();
builder.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
if(android.os.Build.VERSION.SDK_INT >= 21) {
cookieManager.setAcceptThirdPartyCookies(webViewPopUp, true);
cookieManager.setAcceptThirdPartyCookies(webView, true);
}
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(webViewPopUp);
resultMsg.sendToTarget();
return true;
}
@Override
public void onCloseWindow(WebView window) {
//Toast.makeText(contextPop,"onCloseWindow called",Toast.LENGTH_SHORT).show();
try {
webViewPopUp.destroy();
} catch (Exception e) {
Log.d("Destroyed with Error ", e.getStackTrace().toString());
}
try {
builder.dismiss();
} catch (Exception e) {
Log.d("Dismissed with Error: ", e.getStackTrace().toString());
}
}
}
@Override
public void onBackPressed() {
if (webView!=null){
if (webView.canGoBack()){
webView.goBack();
return;
}
}
super.onBackPressed();
}
}

如果您将Firebase用于您的应用程序。我认为您可以在这里找到解决方法： https://firebase.google.com/docs/auth/android/google-signin
祝你好运！
