从GCM获取令牌时出错

Question

import com.google.android.gms.gcm.GoogleCloudMessaging;

public class MainActivity extends AppCompatActivity{

    Button btnRegId;
    EditText etRegId;
    GoogleCloudMessaging gcm;
    String regid;
    String PROJECT_NUMBER;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnRegId = (Button) findViewById(R.id.GCMButton);
        System.out.println("Here!");
        etRegId = (EditText) findViewById(R.id.GCMId);
        PROJECT_NUMBER = "507533032900";
        btnRegId.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                System.out.println("I am here");
                Intent intent = new Intent(v.getContext(),RegistrationIntentService.class);
                startService(intent);

            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

 </manifest>

I have the configuration file generated and stored - as in the Tutorial by Google

I get an error saying

 Failed to complete token refresh
java.lang.SecurityException: Not allowed to start service Intent { act=com.google.android.c2dm.intent.REGISTER pkg=com.google.android.gms (has extras) } without permission com.google.android.c2dm.permission.RECEIVE

What is the error? And how Do I resolve this ?

Answer 1

You resolve this by adding the following permission in your manifest file:

 <!-- [START gcm_permission] -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="com.mypackage.myapp.permission.C2D_MESSAGE" />
 <!-- [END gcm_permission] -->
