在Webview中通过Javascript启动新的Android活动

我有一个android测试应用程序，我正试图用我的JavaScriptInterface类调用一个函数。这个webview播放一个视频，当它结束时调用一个JS方法，该方法应该调用android方法来启动一个新的活动

这似乎根本没有发生，当视频完成时，就像webview重新加载并再次播放视频一样

有可能发起这样的活动吗？我可以在大约45分钟内提供示例代码

VideoActivity.java

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
    getActionBar().hide();
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    setContentView(R.layout.activity_main);


    try
    {
        WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.setWebChromeClient(new WebChromeClient() {
        });
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        Intent i = new Intent("com.example.myapplication.BlankActivity");
        myWebView.addJavascriptInterface(new JavaScriptInterface(this,i), "Android");
        myWebView.loadUrl("url");
    }
    catch(Exception e) {
        String msg = e.getMessage();
        String trace = e.getStackTrace().toString();
    }


}

public class JavaScriptInterface {
    Context mContext;
    Intent i;

    /** Instantiate the interface and set the context */
    JavaScriptInterface(Context c, Intent i) {
        mContext = c;
        this.i = i;
    }

    /** Show a toast from the web page */
    public void onComplete(String toast) {
        startActivity(i);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public class BlankActivity extends Activity {

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.blank, menu);
    return true;
}

}

BlankActivity.java

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
    getActionBar().hide();
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    setContentView(R.layout.activity_main);


    try
    {
        WebView myWebView = (WebView) findViewById(R.id.webview);
        myWebView.setWebChromeClient(new WebChromeClient() {
        });
        WebSettings webSettings = myWebView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        Intent i = new Intent("com.example.myapplication.BlankActivity");
        myWebView.addJavascriptInterface(new JavaScriptInterface(this,i), "Android");
        myWebView.loadUrl("url");
    }
    catch(Exception e) {
        String msg = e.getMessage();
        String trace = e.getStackTrace().toString();
    }


}

public class JavaScriptInterface {
    Context mContext;
    Intent i;

    /** Instantiate the interface and set the context */
    JavaScriptInterface(Context c, Intent i) {
        mContext = c;
        this.i = i;
    }

    /** Show a toast from the web page */
    public void onComplete(String toast) {
        startActivity(i);
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public class BlankActivity extends Activity {

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.blank, menu);
    return true;
}

}

下面是我在视频完成后webview运行的页面上的Javascript代码

function onComplete() {
    Android.onComplete();
}

显示适用的代码，将更容易确定问题所在。嘿，RGraham，感谢您的回复，我添加了示例代码。如果你还需要什么，我会把它寄出去。
