我试图实施新 GCM客户端在Android下，从谷歌的指导方针（的 https://developers.google.com/cloud-messaging/android/client ）。 我收到稍有不同的错误了两个不同的设备。我注意到，我收到的NoSuchMethodError的方法getNoBackupFilesDir这两个设备。 这是logcat的一个Android 4.2.2：

I'm trying to implement the new GCM Client on Android following the guidelines from Google (https://developers.google.com/cloud-messaging/android/client). I'm receiving slightly different errors for two different devices. I noticed that I receive NoSuchMethodError for method getNoBackupFilesDir for both the devices. This is the logcat for an Android 4.2.2:

目前行113我有这样的：

At line 113 I have this:

InstanceID instanceID = InstanceID.getInstance(applicationContext);

这里使用的：

Used here:

// AsyncTask to register Device in GCM Server
private void registerInBackground() {
    new AsyncTask<Void, Void, String>() {
        @Override
        protected String doInBackground(Void... params) {
            String msg = "";

            InstanceID instanceID = InstanceID.getInstance(applicationContext);
            try {
                regId = instanceID.getToken(GCM_SENDER_ID,
                        GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
            } catch (IOException e) {
                e.printStackTrace();
            }

            return msg;
        }

        @Override
        protected void onPostExecute(String msg) {
            if (!TextUtils.isEmpty(regId)) {

                Toast.makeText(
                        applicationContext,
                        "Registered with GCM Server successfully.\n\n"
                                + msg, Toast.LENGTH_SHORT).show();
                Log.e(TAG, "Registered with GCM Server successfully. RegID: " + regId);

            } else { 
                Toast.makeText(
                        applicationContext,
                        "Reg ID Creation Failed.\n\nEither you haven't enabled Internet or GCM server is busy right now. "
                        + "Make sure you enabled Internet and try registering again after some time."
                                + msg, Toast.LENGTH_LONG).show();
                Log.e(TAG, "Reg ID Creation Failed!!!");
            }
        }
    }.execute(null, null, null);
}

我正确导入了谷歌播放服务库，如文档中描述的。（的 https://developers.google.com/android/guides/setup ）

I correctly imported the Google Play Services library as described in the documentation.(https://developers.google.com/android/guides/setup)

有没有人遇到过这种错误？我该如何解决此问题？

Has anyone encountered this errors? How can I resolve this?

推荐答案

我看到，该方法 getNoBackupFilesDir 在android.support.v4.content.ContextCompat发现。

I saw that the method getNoBackupFilesDir is found in android.support.v4.content.ContextCompat.

看来，问题是，我有一个老appcompat-V7包含在项目中。下载与 SDK管理器 的最后一个版本的Andr​​oid支持库键，然后按照步骤进行的添加库与和库添加到您的应用程序项目资源

Seems that the problem was that I had an old appcompat-v7 included in the project. Download with the SDK manager the last version of Android Support Library and then follow the steps for Adding libraries with resources and add the library to your application project.
