在客户端获取GCM令牌时出错-Java 学习之路

包nath.prem.com.premgcmproject;

import android.content.Intent;

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

/ ** *由22/7/16的房屋创建 . * / public class GCMTokenRefreshListenerService扩展InstanceIDListenerService {

//如果更改了令牌，则再次注册设备@Override public void onTokenRefresh（）{Intent intent = new Intent（this，GCMRegistrationIntentService.class）; startService（意向）; }}

Error while getting GCM token in client side

致命异常：IntentService []

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

在

com.google.android.gms.iid.zzd . （未知来源）com.google.android.gms.iid.zzd . （未知来源）com.google.android.gms.iid.InstanceID.zza（未知来源））在com.google.android.gms.iid.InstanceID.getInstance（未知来源）

this is the error I am getting while getting gcm token

公共类GCMRegistrationIntentService扩展IntentService {//成功和错误的常量public static final String REGISTRATION_SUCCESS =“RegistrationSuccess”; public static final String REGISTRATION_ERROR =“RegistrationError”; //类构造函数public GCMRegistrationIntentService（）{super（“”）; } @Override protected void onHandleIntent（Intent intent）{//将gcm注册到设备registerGCM（）; } private void registerGCM（）{//注册完成意图最初为null Intent registrationComplete = null; //注册令牌也为空//我们将在成功注册时获取令牌String token = null; SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences（this）; try {//创建instanceid InstanceID instanceID = InstanceID.getInstance（this）; // // //从实例id获取令牌令牌= instanceID.getToken（getString（R.string.gcm_defaultSenderId），GoogleCloudMessaging.INSTANCE_ID_SCOPE，null）; //在日志中显示令牌，以便我们可以将其复制以发送推送通知//您还可以通过将令牌存储到服务器Log.w（“GCMRegIntentService”，“token：”令牌）来扩展应用程序; //注册完成注册成功完成注册完成=新意图（REGISTRATION_SUCCESS）; //将令牌放入intent // registrationComplete.putExtra（“token”，token）; } catch（Exception e）{//如果发生任何错误Log.w（“GCMRegIntentService”，“Registration error”）; registrationComplete = new Intent（REGISTRATION_ERROR）; } //发送注册完成的广播LocalBroadcastManager.getInstance（this）.sendBroadcast（registrationComplete）; }}

this is the java code of that class

this is my menifest file in the project......But I cannot see any of the logs in RegistrationIntentService:

Try this,

在 build.gradle 中添加 compile 'com.google.android.gms:play-services-gcm:9.0.2' 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("");
    }
