这是我的Gradle控制台的输出,我无法构建我的项目

我在我的应用上实现了GCM通知.我正在尝试在用户注销时取消注册应用程序.我使用以下代码.执行此代码时,它会导致应用程序与以下logcat崩溃:

java.lang.IllegalAccessError: Method 'void android.support.v4.content.ContextCompat.<init>()' is inaccessible to class 'com.google.android.gms.iid.zzd' (declaration of 'com.google.android.gms.iid.zzd' appears in /data/app/com.example.packagename-1/base.apk)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

这是代码:

InstanceID instanceID = InstanceID.getInstance(WelcomeActivity.this);
try {
   instanceID.deleteInstanceID();
   Utility.logCatMsg("Logged Out Success!!!");
} catch (IOException e) {
   Utility.logCatMsg("Exception while logging out: "+e.getMessage());
   e.printStackTrace();
}

我面临的问题是，当时间更改时，TIME_TICK 仅在应用程序运行时调用。但我希望即使应用程序正在运行或不使用广播接收器也能调用它。

主要活动

public class MainActivity extends Activity {
      @Override
      public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      Toast.makeText(getApplicationContext(), "Checking", Toast.LENGTH_LONG).show();
      }
    } 

我的广播接收器

public class MyBroadastReceiversextends BroadcastReceiver
{

    @Override
    public void onReceive(Context arg0, Intent arg1) {

        Toast.makeText(arg0, "Toast Receive", Toast.LENGTH_LONG).show();
    }
}

菜单文件

    <receiver android:name="com.example.serviceschecking.MyBroadastReceivers" android:enabled="true" android:exported="true">  
       <intent-filter >
           <action android:name="android.intent.action.TIME_TICK"/>
       </intent-filter>
</receiver>
