每次在我的应用程序中调用navigator.app.exitApp（）时，应用程序都会崩溃。请在我收到的崩溃日志下面找到。

以下代码是我的主要活动文件： -

public class MathWhiz extends CordovaActivity 
{
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        super.init();
        // Set by <content src="index.html" /> in config.xml
        super.loadUrl(Config.getStartUrl());

        //super.loadUrl("file:///android_asset/www/index_android.html");

        try {
            String pName = this.getClass().getPackage().getName();
            this.copy("Databases.db", "/data/data/" + pName + "/app_database/");
            this.copy("0000000000000001.db", "/data/data/" + pName
                    + "/app_database/file__0/");
        } catch (IOException e) {
            e.printStackTrace();
        }

       // super.loadUrl("file:///android_asset/www/index_android.html",3000);
    }

    void copy(String file, String folder) throws IOException {

        File CheckDirectory;
        CheckDirectory = new File(folder);
        if (!CheckDirectory.exists()) {
            CheckDirectory.mkdir();
        }

        InputStream in = getApplicationContext().getAssets().open(file);
        OutputStream out = new FileOutputStream(folder + file);

        // Transfer bytes from in to out
        byte[] buf = new byte[1024];
        int len;
        while ((len = in.read(buf)) > 0)
            out.write(buf, 0, len);
        in.close();
        out.close();

这个问题在phonegap版本2.9.0中没有出现。开始发生3.1.0。请告诉我与之相关的问题。提前谢谢。

Answer 1

根据file，设备插件注册接收器以侦听电话操作。因此，请确保您已添加所需的权限，以使Telephony在Android.Manifest.xml文件中正常工作。

navigator.app.exitApp（）在phonegap 3.1.0上崩溃了
