**1、处理闪屏的问题需要在valus下的styles.xml下处理**

下面是路径没有就新建一个

主要的就是选中的那个

在AndroidManifest.xml配置一下

上面配合完成就不闪了

2、启动太慢怎么处理的问题

我使用的是

InitService

import android.app.IntentService;
    import android.content.Context;
    import android.content.Intent;
    import android.os.Build;
    
    import com.umeng.analytics.MobclickAgent;
    
    
    import cn.jpush.android.api.JPushInterface;
    
    /**
     * An {@link IntentService} subclass for handling asynchronous task requests in
     * a service on a separate handler thread.
     * <p>
     * <p>
     * app  开启的时候 初始化 操作  减少app 开启的效率
     * TODO: Customize class - update intent actions, extra parameters and static
     * helper methods.
     */
    public class InitService extends IntentService {
        // TODO: Rename actions, choose action names that describe tasks that this
        // IntentService can perform, e.g. ACTION_FETCH_NEW_ITEMS
        private static final String ACTION_FOO = "com.xinli.vkeeper.services.action.FOO";
    
    
        /**
         * Instantiates a new Init service.
         */
        public InitService() {
            super("InitService");
        }
    
        /**
         * Starts this service to perform action Foo with the given parameters. If
         * the service is already performing a task this action will be queued.
         *
         * @param context the context
         * @see IntentService
         */
    // TODO: Customize helper method
        public static void startActionFoo(Context context) {
            try {
                Intent intent = new Intent(context, InitService.class);
                intent.setAction(ACTION_FOO);
    
            /*    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    context.startForegroundService(intent);
                } else {*/
                    context.startService(intent);
               // }
            } catch (Exception e) {
                e.printStackTrace();
    
            }
    
        }
    
    
        @Override
        protected void onHandleIntent(Intent intent) {
            if (intent != null) {
                final String action = intent.getAction();
                if (ACTION_FOO.equals(action)) {
                    LoadInit();
                }
            }
        }
    
    
        /**
         * 初始化操作数据
         */
        private void LoadInit() {
            CrashHandler crashHandler = CrashHandler.getInstance();
            crashHandler.init(MyApplication.getAppContext());
            JPushInterface.init(MyApplication.getAppContext());
            if (JPushInterface.isPushStopped(MyApplication.getAppContext())) {
                JPushInterface.resumePush(MyApplication.getAppContext());
            }
            MobclickAgent.setCatchUncaughtExceptions(true);
            MobclickAgent.startWithConfigure(new MobclickAgent.UMAnalyticsConfig(MyApplication.getAppContext(), Config.KEY,"Umeng", MobclickAgent.EScenarioType.E_UM_ANALYTICS_OEM,true));
    
            MobclickAgent.enableEncrypt(true);
            MobclickAgent.setCheckDevice(true);
    
        }
    
    }

在application中这样使用就好了

InitService.startActionFoo(context);
