我在應(yīng)用中使用Google通知，到目前為止，我在清單中做了以下操作：<!-- GCM --><uses-permission android:name="android.permission.GET_ACCOUNTS" /> <!-- GCM requires a Google account. --><uses-permission android:name="android.permission.WAKE_LOCK" /> <!-- Keeps the processor from sleeping when a message is received. --> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- This app has permission to register and receive data message. --> <!-- Creates a custom permission so only this app can receive its messages. NOTE: APP_PACKAGE.permission.C2D_MESSAGE -->   <permission android:name="com.myapp.permission.C2D_MESSAGE" android:protectionLevel="signature" /><uses-permission android:name="com.myapp.permission.C2D_MESSAGE" />    <!-- END GCM -->在我將Nexus 7更新為Android 5.0之前，它一直運(yùn)行良好?，F(xiàn)在，當(dāng)我嘗試使用Eclipse在此設(shè)備中安裝應(yīng)用程序時(shí)，出現(xiàn)以下錯(cuò)誤：INSTALL_FAILED_DUPLICATE_PERMISSION perm = com.myapp.permission.C2D_MESSAGE pkg = com.myapp我不明白這是怎么回事...直到Android 5.0，它都可以正常工作。我知道，我使用C2D_MESSAGE的兩條線(xiàn)，permission并uses-permission但我已經(jīng)復(fù)制從原來(lái)的谷歌GCM指南，代碼，因此它必須是罰款。
