Question

我创建并发布了一个非常简单的Android应用程序，主要由WebView组成。我没有收到任何关于崩溃或错误的报告，除了我的一个朋友甚至无法启动应用程序。有问题的手机是运行Android 2.2.2版本的摩托罗拉Defy（MB525）。每当我的朋友尝试打开应用程序时，都会显示一条错误消息，指出进程已意外停止，请重试。

我已经在虚拟设备上运行该应用程序，摩托罗拉Droid运行Android版本2.3.7，这与我的朋友的手机尽可能接近，但由于应用程序运行顺利，我无法重现问题。在Motorola Defy或Android 2.2.2版上使用WebView的应用程序是否存在任何已知问题？或者有人可以给我任何关于如何解决这个问题的提示吗？

MainActivity.java

import com.google.android.gms.ads.AdRequest;

import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;

public class MainActivity extends Activity {

//***Not used***
@SuppressWarnings("unused")
private boolean services() {
    int isAvailable = GooglePlayServicesUtil
            .isGooglePlayServicesAvailable(this);
    if (isAvailable == ConnectionResult.SUCCESS) {
        return true;
    } else {
        Toast.makeText(this, "Google Play Services ej tillgänglig", Toast.LENGTH_SHORT)
                .show();
    }
    return false;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    //***AdMob Banner***
    AdView adView = (AdView)this.findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);



    //***WebView start***
    WebView myWebView = (WebView) findViewById(R.id.webView1);

    myWebView.setWebViewClient(new WebViewClient());
    WebSettings webSettings = myWebView.getSettings();
    //Zoombuttons
    myWebView.getSettings().setBuiltInZoomControls(true);
    myWebView.getSettings().setUseWideViewPort(true);

    webSettings.setSupportZoom(true);
    webSettings.setJavaScriptEnabled(true);
    myWebView.loadUrl("http://www.sebastianliljegren.se/inoff/android/lista.php");
    //***Webview end***
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    WebView myWebView = (WebView) findViewById(R.id.webView1);
    // Check if the key event was the Back button and if there's history
    if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {
        myWebView.goBack();
        return true;
    }
    // If it wasn't the Back key or there's no web page history, bubble up to the default
    // system behavior (probably exit the activity)
    return super.onKeyDown(keyCode, event);
}

}

Answer 1

由于在Android 2.2上缺乏对Google Play服务的支持，因此无效。立即行动！

WebView应用程序无法使用Motorola Defy（MB525）和/或Android 2.2.2
