我尝试根据 Google 手册使用 GCM 服务创建测试应用程序https://developer.android.com/google/gcm/client.html#app https://developer.android.com/google/gcm/client.html#app
但是当我收到消息时 - 我遇到了这个错误:
无法实例化接收器
com.example.testpushnotification.GcmBroadcastReceiver:
java.lang.ClassNotFoundException:未找到类
路径上的“com.example.testpushnotification.GcmBroadcastReceiver”:
DexPathList[[zip 文件
“/data/app/com.example.testpushnotification-2.apk”],
nativeLibraryDirectories=[/data/app-lib/com.example.testpushnotification-2,
/供应商/lib,/系统/lib]]
我一直在寻找所有相同的问题,但他们没有解决方案,或者解决方案没有帮助,或者它们已被弃用。
我的清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<category android:name="com.example.testpushnotification"/>
</intent-filter>
</receiver>
<service android:name=".GcmIntentService"/>
</application>
以及 com.example.testpushnotification 包中 GcmBroadcastReceiver 的源代码:
public class GcmBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// Explicitly specify that GcmIntentService will handle the intent.
ComponentName comp = new ComponentName(context.getPackageName(),
GcmIntentService.class.getName());
// Start the service, keeping the device awake while it is launching.
startWakefulService(context, (intent.setComponent(comp)));
setResultCode(Activity.RESULT_OK);
}
为什么 Dex 路径包含与我不同的包?
请问,如何解决?
FIXED改变了<receiver
android:name=".GcmBroadcastReceiver"
..
</receiver>
to <receiver
android:name="com.google.android.gcm.GCMBroadcastReceiver"
..
</receiver>
