获取Android设备令牌

Question

我正在集成Pushwoosh API，用于需要设备令牌的推送通知。如何获取：

我得到空字符串使用这个：

String deviceToken=GCMRegistrar.getRegistrationId(getApplicationContext()); 

这些是我在AndroidMainfest.xml:中拥有的权限

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"/>
<uses-permission android:name="android.permission.INTERNET" />
<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" />
<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
<application ...>
    <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.example.gcm" />
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService" />
</application>

这是获取设备令牌的正确方法吗。

您的代码看起来很好，只需将您的AndroidManifest与下面的代码进行比较，以确保您没有遗漏任何内容-

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17"/>
<uses-permission android:name="android.permission.INTERNET" />
<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" />
<permission android:name="com.example.gcm.permission.C2D_MESSAGE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" />
<application ...>
    <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="com.example.gcm" />
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService" />
</application>

希望这有帮助：）

试试下面的代码，希望它能帮助你

    GCMRegistrar.checkDevice(getApplicationContext());
    GCMRegistrar.checkManifest(getApplicationContext());    
    final String regId = GCMRegistrar.getRegistrationId(this);
