这是我的ParseUtils.java类

  public class ParseUtils {private static String TAG = ParseUtils.class.getSimplename();public static voID verifyParseConfiguration(Context context) {    if (TextUtils.isEmpty(AppConfig.PARSE_APPliCATION_ID) || TextUtils.isEmpty(AppConfig.PARSE_CLIENT_KEY)) {        Toast.makeText(context, "Please configure your Parse Application ID and ClIEnt Key in AppConfig.java", Toast.LENGTH_LONG).show();        ((Activity) context).finish();    }}public static voID registerParse(Context context) {    // initializing parse library    Parse.initialize(context, AppConfig.PARSE_APPliCATION_ID, AppConfig.PARSE_CLIENT_KEY);    ParseInstallation.getCurrentInstallation().saveInBackground(); //Shows error heree    ParsePush.subscribeInBackground(AppConfig.PARSE_CHANNEL, new SaveCallback() {        @OverrIDe        public voID done(ParseException e) {            Log.e(TAG, "Successfully subscribed to Parse!");        }    });}public static voID subscribeWithEmail(String email) {    ParseInstallation installation = ParseInstallation.getCurrentInstallation();    installation.put("email", email);    installation.saveInBackground();    Log.e(TAG, "Subscribed with email: " + email);}}

这是MyApplication

    public class MyApplication extends Application {private static MyApplication mInstance;@OverrIDepublic voID onCreate() {    super.onCreate();    mInstance = this;    // register with parse    ParseUtils.registerParse(this);}public static synchronized MyApplication getInstance() {    return mInstance;}}

这是NotificationUtils类

public class NotificationUtils {private String TAG = NotificationUtils.class.getSimplename();private Context mContext;public NotificationUtils() {}public NotificationUtils(Context mContext) {    this.mContext = mContext;}public voID showNotificationMessage(String Title, String message, Intent intent) {    // Check for empty push message    if (TextUtils.isEmpty(message))        return;    if (isAppIsInBackground(mContext)) {        // notification icon        int icon = R.mipmap.ic_launcher;        int smallicon = R.drawable.ic_push;        int mNotificationID = AppConfig.NOTIFICATION_ID;        PendingIntent resultPendingIntent =                PendingIntent.getActivity(                        mContext,                        0,                        intent,                        PendingIntent.FLAG_CANCEL_CURRENT                );        NotificationCompat.InBoxStyle inBoxStyle = new NotificationCompat.InBoxStyle();        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(                mContext);        Notification notification = mBuilder.setSmallicon(smallicon).setTicker(Title).setWhen(0)                .setautoCancel(true)                .setContentTitle(Title)                .setStyle(inBoxStyle)                .setContentIntent(resultPendingIntent)                .setSound(ringtoneManager.getDefaultUri(ringtoneManager.TYPE_NOTIFICATION))                .setLargeIcon(BitmapFactory.decodeResource(mContext.getResources(), icon))                .setContentText(message)                .build();        notificationmanager notificationmanager = (notificationmanager) mContext.getSystemService(Context.NOTIFICATION_SERVICE);        notificationmanager.notify(mNotificationID, notification);    } else {        intent.putExtra("Title", Title);        intent.putExtra("message", message);        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_top);        mContext.startActivity(intent);    }}/** * Method checks if the app is in background or not * * @param context * @return */public static boolean isAppIsInBackground(Context context) {    boolean isInBackground = true;    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);    if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT_WATCH) {        List<ActivityManager.RunningAppProcessInfo> runningProcesses = am.getRunningAppProcesses();        for (ActivityManager.RunningAppProcessInfo processInfo : runningProcesses) {            if (processInfo.importance == ActivityManager.RunningAppProcessInfo.importANCE_FOREGROUND) {                for (String activeProcess : processInfo.pkgList) {                    if (activeProcess.equals(context.getPackagename())) {                        isInBackground = false;                    }                }            }        }    } else {        List<ActivityManager.RunningTaskInfo> taskInfo = am.getRunningTasks(1);        Componentname componentInfo = taskInfo.get(0).topActivity;        if (componentInfo.getPackagename().equals(context.getPackagename())) {            isInBackground = false;        }    }    return isInBackground;}}

请帮我.

解决方法:

通过删除解决了错误

  ParsePush.subscribeInBackground(AppConfig.PARSE_CHANNEL, new SaveCallback() {    @OverrIDe    public voID done(ParseException e) {        Log.e(TAG, "Successfully subscribed to Parse!");    }});

并且仅使用

  ParseInstallation.getCurrentInstallation().saveInBackground();
