如何检测是否安装了Google Play ?(不是市场)



无论安装的应用程序名为Google Play还是Market,包名都是相同的com.android.vending

我需要能够检测应用程序是Google Play还是Market,我已经检查了PackageInfo,除了versionCodeversionName之外没有什么可以帮助。

有谁知道第一个versionCode是什么或versionName是谷歌Play应用程序?

如果有人知道任何其他检测方法请告诉我

我知道如何检查应用程序标签。我正在使用调试器来查看packageInfo中返回的所有内容,这就是为什么我最初没有看到它的原因。

public static boolean isGooglePlayInstalled(Context context) {
    PackageManager pm = context.getPackageManager();
    boolean app_installed = false;
    try
    {
           PackageInfo info = pm.getPackageInfo("com.android.vending", PackageManager.GET_ACTIVITIES);
           String label = (String) info.applicationInfo.loadLabel(pm);
           app_installed = (label != null && !label.equals("Market"));
    }
    catch (PackageManager.NameNotFoundException e)
    {
           app_installed = false;
    }
    return app_installed;
}

您也可以尝试这个简化的解决方案:

public boolean isGooglePlayAvailable() {
        boolean googlePlayStoreInstalled;
        int val= GooglePlayServicesUtil.isGooglePlayServicesAvailable(LocationActivity.this);
        googlePlayStoreInstalled = val == ConnectionResult.SUCCESS;
        return googlePlayStoreInstalled;
    }

在我的应用程序中,我检查打开play store的可能性,然后像这样:

    public static boolean isResolveActivity(Intent intent) {
            return App.getInstance().getPackageManager().resolveActivity(intent, PackageManager.GET_RESOLVED_FILTER) != null;
        }
   public void isResolveActivity(String appPackage) {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackage));
      if(isResolveActivity(intent)){
      ...open intent
      }
  }

您可以使用这段简单的代码,它很简单,并且考虑到使用GooglePlayServicesUtil:

不需要重新发明轮子。
public static boolean isPlayStoreInstalled(Context context){
try {
    context.getPackageManager()
            .getPackageInfo(GooglePlayServicesUtil.GOOGLE_PLAY_STORE_PACKAGE, 0);
    return true;
} catch (PackageManager.NameNotFoundException e) {
    return false;
}
}

这将需要你把这个添加到你的依赖项中:

compile 'com.google.android.gms:play-services-base:[PLAY_SERVICES_VERSION]'

最新play-services版本:10.0.1

这可能是一个更好的例子,因为它允许状态',用户可以对它做一些事情,如重新认证或更新。基于GCM客户端示例项目中的代码:

 public static boolean checkPlayServices(Activity activity) {
        int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(activity);
        if (resultCode != ConnectionResult.SUCCESS) {
            if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
                GooglePlayServicesUtil.getErrorDialog(resultCode, activity,
                        PLAY_SERVICES_RESOLUTION_REQUEST).show();
            } else {
                Toast.makeText(activity.getApplicationContext(), "This device is not supported.", Toast.LENGTH_LONG).show();
                activity.finish();
            }
            return false;
        }
        return true;
    }
