在客户端获取GCM令牌时出错

Question

包装nath.prem.com.premgcmproject；

进口android.content.Intent；

导入com.google.android.gms.iid.InstanceIDListenerService；

/** *由prem在22/7/16上创建。*公共类GCMTokenRefreshListenerService扩展InstanceIDListenerService {

//如果令牌被更改，则重新注册设备@覆盖公共无效的onTokenRefresh() {意向=新的意图(此，GCMRegistrationIntentService.class)；startService(意图)；}}

在客户端中获取GCM令牌时出错

致命例外: IntentService[]

java.lang.IncompatibleClassChangeError: android.support.v4.content.ContextCompat at com.google.android.gms.iid.zzd.zzdL(未知来源)

在…

(未知源)在com.google.android.gms.iid.InstanceID.zza(Unknown源(com.google.android.gms.iid.zzd.)在com.google.android.gms.iid.InstanceID.getInstance(Unknown源)

这是我在获取gcm令牌时遇到的错误

公共类GCMRegistrationIntentService扩展IntentService {//常量以表示公共静态最终字符串REGISTRATION_SUCCESS = "RegistrationSuccess"；公共静态最终字符串REGISTRATION_ERROR = "RegistrationError"；//类构造函数公共GCMRegistrationIntentService() {Super(“)；}@重写受保护的onHandleIntent(意图){//将gcm注册到设备registerGCM()；}私有无效registerGCM() {//注册完成意图初始为空意图registrationComplete =空；//寄存器令牌也为空//我们将获得成功的完全注册字符串令牌=空；PreferenceManager.getDefaultSharedPreferences(this)；sharedPreferences = SharedPreferences sharedPreferences=sharedPreferences sharedPreferences= instanceid InstanceID = InstanceID.getInstance(this)；/从实例id令牌获取令牌= instanceID.getToken(getString(R.string.gcm_defaultSenderId)，GoogleCloudMessaging.INSTANCE_ID_SCOPE，null)；//在日志中显示令牌，以便我们可以复制它以发送推送通知//您还可以通过将令牌存储到服务器Log.w("GCMRegIntentService"，“令牌：”+令牌)来扩展应用程序；//在注册时完成创建意图( registrationComplete =新意图(REGISTRATION_SUCCESS)；//将令牌发送给意图//registrationComplete.putExtra(“令牌”，令牌)；} catch (异常e) {//如果发生任何错误，则为Log.w("GCMRegIntentService"，“注册错误”)；registrationComplete =新意图(REGISTRATION_ERROR)；}//发送已完成注册的广播

--这是类的java代码

​

--这是我在project......But中最重要的文件--我在RegistrationIntentService:中看不到任何日志

，，试试这个

在compile 'com.google.android.gms:play-services-gcm:9.0.2'中添加build.gradle依赖项

 private void registerToGCM() {
        new AsyncTask<String, String, String>() {
            ProgressDialog progressDialog;
            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                progressDialog = new ProgressDialog(LoginActivity.this);
                progressDialog.setMessage(getString(R.string.gcm_register_message));
                progressDialog.setCancelable(false);
                progressDialog.show();
            }
            @Override
            protected String doInBackground(String... params) {
                String registryId = null;
                try {
                    InstanceID instanceID = InstanceID.getInstance(getApplicationContext());
                    registryId = instanceID.getToken(getString(R.string.gcm_defaultSenderId), GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);
                } catch (Exception ex) {
                    Log.e("MAINACIVITY", "gcm register Error " + ex.toString());
                }
                return registryId;
            }

            @Override
            protected void onPostExecute(String registeredId) {
                super.onPostExecute(registeredId);
                progressDialog.dismiss();
                // perform action here
            }
        }.execute("");
    }
