错误 Google 登录于 Android

Question

我的应用说：

Google play services is not available. this application will close

我使用的代码是https://github.com/googleplus/gplus-quickstart-android

有什么建议吗？

Answer 1

不清楚您是否在检查设备上是否安装了 GooglePlayServices。我没有在您链接的代码中看到检查。

This webpage describes how to verify that GooglePlayServices is installed on a device and how to handle failures. The information is not completely current, but still provides a good outline of the processing. The GooglePlayServicesUtil class 提供检查是否安装了 PlayServices 的方法，如果缺少，则显示一个对话框以允许用户安装它。

部分代码来自网页：

private boolean checkPlayServices() {
    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (status != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(status)) {
            showErrorDialog(status);
        } else {
            Toast.makeText(this, "This device is not supported.",
                    Toast.LENGTH_LONG).show();
            finish();
        }
        return false;
    }
    return true;
}

private int REQUEST_CODE = 1234;

private void showErrorDialog(int code) {
    GooglePlayServicesUtil.getErrorDialog(code, this, REQUEST_CODE).show();
}

我在这里玩一些代码给你建议：

  strings.xml:

 <string name="lbl_play_service">This application needs Google Play Service, you must install it first.</string>
    <string name="play_service_url">market://details?id=com.google.android.gms</string>
<string name="play_service_web">https://play.google.com/store/apps/details?id=com.google.android.gms</string>

Some javas:

    @Override
protected void onResume() {
    super.onResume();
    checkPlayService();
}

/**
 * To confirm whether the validation of the Play-service of Google Inc.
 */
private void checkPlayService() {
    final int isFound = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (isFound == ConnectionResult.SUCCESS) {
       //Device has updated version of play-service.
    } else {
       //You need to store to update play-service.
        new Builder(this).setTitle(R.string.application_name).setMessage(R.string.lbl_play_service).setCancelable(
                false).setPositiveButton(R.string.btn_yes, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                dialog.dismiss();
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(Uri.parse(getString(R.string.play_service_url)));
                try {
                    startActivity(intent);
                } catch (ActivityNotFoundException e0) {
                    intent.setData(Uri.parse(getString(R.string.play_service_web)));
                    try {
                        startActivity(intent);
                    } catch (Exception e1) {
                        //Ignore now.
                    }
                } finally {
                    finish();
                }
            }
        }).create().show();
    }
}
