我正在尝试让GCM在带有android 4.0.4的设备上运行。 首先,从设备发送到服务器到另一个设备是没有问题的,它是接收部分将无法工作。其次,我也在使用带有android 5的设备,在那款手机上它一切正常。我认为它可能与设备有关,但我不确定(MEDION p4013)。它是android 4.0.4所以你不需要一个谷歌帐户来使它工作,但要确保我也在手机上激活了一个帐户,但仍然没有结果。
这是我的清单:

广播接收器:
@Override
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(), GCMMessageHandler.class.getName());
Log.d("received", "message");
startWakefulService(context, intent.setComponent(comp));
setResultCode(Activity.RESULT_OK);
}
和处理程序:
private Handler handler;
public GCMMessageHandler() {
super("GCMMessageHandler");
}
@Override
public void onCreate() {
super.onCreate();
handler = new Handler();
}
@Override
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
final int challengeId = Integer.parseInt(extras.getString("challenge_id"));
final String message = extras.getString("message");
handler.post(new Runnable() {
@Override
public void run() {
if(challengeId == -1) {
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_LONG).show();
} else {
//TODO implementatie
}
}
});
GCMBroadCastReceiver.completeWakefulIntent(intent);
}
答案 0 :(得分:1)
好的,我找到了,
问题出在app的build.gradle中。 applicationId与应用程序的包名称不匹配。显然,对于旧版本的Android,您会遇到问题,但是对于较新版本,它会自动将其更改为某个地方。
