android - GooglePlayServicesUtil.getErrorDialog为空

我正在使用ACRA(arca.ch)生成自动错误报告。

我刚刚使用Google Maps Android API v2发布了我的应用程序的新版本。尝试显示GooglePlayServicesUtil.getErrorDialog返回的对话框时，EEEPad和Transformer Pad用户报告了一个错误。有谁知道为什么会这样？

这是acra报告的相关代码和Logcat:

拨打此行时:

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
if(resultCode != ConnectionResult.SUCCESS)
{
        //The dialog that comes back is null (probably due to the logcat message)
        Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, this, 69);
        //So when I call the next line, the app crashes with a NullPointerException
        dialog.show();
}
...

Logcat:

12-18 04:21:04.531 W/GooglePlayServicesUtil( 3977): Google Play Store signature invalid.
12-18 04:21:04.551 E/GooglePlayServicesUtil( 3977): Google Play services is invalid. Cannot recover.

在此先感谢您提供的任何帮助。

更新

google尚未解决该问题，一旦听到任何声音，我将更新此问题(有关Google Bug报告的链接，请参阅CommonsWare的回答)。同时，如果您遇到此问题并且不希望您的应用崩溃，这是我目前正在做的事情:

public void checkGooglePlayServicesAvailability()
{
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if(resultCode != ConnectionResult.SUCCESS)
    {
        Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, this, 69);
        if(dialog != null)
        {
            dialog.show();
        }
        else
        {
            showOkDialogWithText(this, "Something went wrong. Please make sure that you have the Play Store installed and that you are connected to the internet. Contact developer with details if this persists.");
        }
    }

    Log.d("GooglePlayServicesUtil Check", "Result is: " + resultCode);
}

public static void showOkDialogWithText(Context context, String messageText)
{
    Builder builder = new AlertDialog.Builder(context);
    builder.setMessage(messageText);
    builder.setCancelable(true);
    builder.setPositiveButton("OK", null);
    AlertDialog dialog = builder.create();
    dialog.show();
}

最佳答案

如果结果代码是getErrorDialog()，SERVICE_MISSING或SERVICE_VERSION_UPDATE_REQUIRED，则Google suggests(也在docs中)调用SERVICE_DISABLED。因此，可能是最后一个可能的状态码(SERVICE_INVALID)是引起问题的原因。

我正在使用以下代码，到目前为止，它似乎可以正常运行(在仿真器中，平台2.3.3进行测试):

int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(activity.getApplicationContext());
if (resultCode == ConnectionResult.SUCCESS) {
    activity.selectMap();
} else if (resultCode == ConnectionResult.SERVICE_MISSING ||
           resultCode == ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED ||
           resultCode == ConnectionResult.SERVICE_DISABLED) {
    Dialog dialog = GooglePlayServicesUtil.getErrorDialog(resultCode, activity, 1);
    dialog.show();
}
