android - GooglePlayServicesUtil.getErrorDialog 为空

Question

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。我在尝试显示 GooglePlayServicesUtil.getErrorDialog 返回的对话框时收到 EEEPad 和 Transformer Pad 用户报告的错误。有谁知道为什么会发生这种情况？

这是acra报告的相关代码和Logcat:

调用此行时:

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.

提前感谢您提供的任何帮助。

更新

谷歌尚未解决此问题，我将在听到任何消息后更新此问题(请参阅 CommonsWare 对 Google 错误报告链接的回答)。同时，如果您遇到此问题并且不希望您的应用崩溃，我目前正在做的是:

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();
}

Answer 1

谷歌 suggests (也在 docs 中)如果结果代码是 SERVICE_MISSING、SERVICE_VERSION_UPDATE_REQUIRED 或 SERVICE_DISABLED，则调用 getErrorDialog()。所以可能是最后一个可能的状态代码 (SERVICE_INVALID) 是造成问题的原因。

我正在使用以下代码，到目前为止它似乎工作正常(在模拟器中测试，平台 2.3.3):

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();
}
